How to make a nail from wire. Nails - types and applications. Features of nail making machine

How did ancient people make nails? The first nails were invented back in primitive times; they were made from hard wood, fastening together the wooden parts of a home or other buildings. Nails were also made from other natural materials, using fish bones or sharp plant thorns. In the Borovichi district there is a nail museum, where you can see nails from different times, ranging from wooden ones, of different sizes and brands.

By the way, wooden nails have never lost their relevance. At the beginning of the 20th century, village shoemakers skillfully hammered miniature birch nails into the soles of their boots. The birch stilettos swelled from the water and held the soles tightly.

The answer to the question of when and from what metal nails were made in the old days suggests itself. The first metal nails began to be made in the Bronze Age, casting or forging them from copper and bronze, and subsequently, in the Iron Age, from a more durable material - iron.

Nails are one of the most popular and oldest rolled metal products in its entire history.

The first nails were essentially forged products; at the moment, due to the invention of wire and its enormous distribution, this technology has been safely forgotten. A better and much easier way to produce nails was found than ordinary forging (and there were not enough blacksmiths).

The appearance of wire not only simplified and made it cheaper to produce nails, but also made it possible to significantly expand the range of products.

Following the wire, special nailing machines appeared, the task of which was to make nails from wire.

These nailing machines create nails using the cold forging principle.

Considering the modern process of creating nails, it is worth noting that not any metal is suitable for the production of nails (soft metal is not suitable, since when driving a nail with a hammer it simply...

Information for the material on the production of nails was taken from the book by S. I. Dashevsky “Production of Nails”, published in 1960. The book is old, so perhaps modern nails are made a little differently, but the basic technology has probably remained unchanged, since the appearance and purpose of the nail have not changed over the past 50 years.

In the mass production of nails, the following technological scheme has been adopted: threading unwinding devices - threading wire into the machine - straightening the wire - feeding wire to the size of the nail - clamping the wire with dies - biting off the wire with trimming knives - dropping nails by rebound - landing...

Nails. Their types and applications

Ordinary nails are made from thermally untreated steel and even from steel wire (soft). They are marked with two numbers: the first indicates the diameter of the rod, the second indicates the length in millimeters. They have a flat, smooth or corrugated cap. Wire nails with a countersunk head are used when you need to hide the head. By driving a nail using a countersink, you can prepare the surface of the board for further putty.

Corrugated, screw, club nails and brushes for hanging pictures have a shaft with longitudinal, transverse, helical grooves, dents or burrs. They have greater resistance to pulling.

Nails made of heat-treated steel (hardened) can be driven into walls made of brick and even lightweight concrete. But these nails are fragile, which must be taken into account when working with them.

Plaster, tar paper, and wallpaper nails are used for fastening low-strength materials to a rigid base. They have a shorter...

History of the nail

Do you remember what chaos began in the house when one of the characters in Jerome K. Jerome’s story “Three Men in a Boat (Not Counting the Dog)” - Uncle Podger - undertook to do something around the house? One day he decided to hang a picture. Where did you start? From the nails... “He sends the maid to buy sixpence worth of nails, and after her one of the boys to tell her what size the nails should be.”

It is probably not an exaggeration to say that one of the most popular household goods is the most common nail. And in any house there will probably be nails. How else? After all, without them, you can’t make repairs, or hang a picture on the wall, and often they help a home handyman fix shoes. But a nail is needed not only in everyday life. Without large nails - crutches - it is impossible to lay a railway; neither furniture, nor shoe, nor other factories can do without a nail. It is needed in construction and shipbuilding - in a word, not...

The first nails were made from natural materials, such as fish bones and plant thorns, or hewn from hard wood.

The appearance of the first metal nails dates back to the Bronze Age, when they were cast or forged. Subsequently, wire - iron or copper - began to serve as the material for the production of nails. Thus, the Bible reports on the purchase of iron for nails by King David. Bronze nails have been found during excavations of buildings in Ancient Egypt and other ancient cultures. Historical sources report the use of nails in the Roman Empire to nail criminals to wooden crosses. In Russia, references to nail masters have been known since the 13th century.

Initially, nail production was manual and expensive. Nails became an affordable commodity only at the beginning of the 19th century with the advent of machines for making forged nails and wire nails (the first machine, put into mass production in the early 1800s, was patented in 1790). By the end of the XIX...

Nail production technology

A little history:
The first nails were forged. It is known that in ancient times the Greeks and Romans used rather long nails forged from a copper alloy to build ships. These nails were tetrahedral in cross-section and tapered from the head to the sharp end.
With the development of iron processing, nails using the hot forging method naturally began to be made from iron, which was less expensive than copper. Blacksmiths forged them both for construction and for attaching horseshoes to horses' hooves.
Nails for fastening horseshoes are called uhnals. Until now, they are mainly made using the hot forging method, since they have a rather complex shape. They are rectangular in cross-section with a rather high head (5-8 mm). The head also has a rectangular cross-section (Fig. 1)

It would seem that it is simpler than an ordinary nail? Meanwhile, this is a product that can be produced in the required quantity with the proper quality, only using high-tech equipment and proven raw materials. Of course, we are talking specifically about the product, and not about the “model”.

The starting material for nails is wire. Each type of product uses its own wire size and material. The most common steel upholstery nails are made from non-heat-treated steel, grades St 3 KP, St3 PS, St 1 KP, St 2 KP. In general, the wire can be copper or even aluminum. Wire for the production of nails is supplied in coils that are convenient for unwinding (Fig. 1).

Modern equipment for the production of nails is a compact automatic line. In appearance this is one “machine”, but in fact it is several pieces of equipment compactly integrated into a common body (Fig. 2).

A nail is the simplest fastening tool, known since ancient times. The nail has been in human use for about five thousand years.
The nail is used everywhere and for various purposes. Without a nail, they can neither make repairs nor hang a picture on the wall, and they often help a home handyman repair shoes. But a nail is needed not only in everyday life. Without large nails - crutches - it is impossible to lay a railway; neither furniture, nor shoe, nor other factories can do without a nail. It is needed in both construction and shipbuilding.

Nails appeared in primitive man. He used fish and animal bones, plant thorns, pointed roots and tree chips as nails. They were used to fasten parts of buildings and boats, and to nail down skins that served as protection from wind and snow.

Excavations in one of the oldest centers of civilization - Ancient Mesopotamia, located between the Tigris and Euphrates rivers in Western Asia, discovered pointed clay rods, shaped very similar to acorns. This...

There are all sorts of nail heads: grooved, smooth, with a screw. There are dozens of types of nails. In this article we will try to figure out where to drive a nail, and where rust will simply eat it.

Nail fastening is often considered one of the simplest fastening methods, although it is not always reliable or durable if the nail is not handled correctly.

Construction professionals use different types of nails of different sizes and with different heads. For boards you need stainless nails, for logs - galvanized nails, for concrete - brass or copper nails, for drywall - plastic nails, and you should also be careful when choosing nails with a wide, narrow head or no head at all.

Forge; - anvil; - blacksmith hammer; - tongs; - vice; - cutting (chisel); - nail shop; - round bar.

Instructions

Take a round rod about a meter long and 10-12 mm in diameter. Heat one end of it in a forge. At a distance of about 50 mm from the beginning of the rod, make a pinch in one plane. Rotate the rod 90 degrees along the longitudinal axis and perform the same clamping in another plane. As a result, the cross-section of the workpiece in the pinched area will be square, approximately 10x10 mm in size.

Pull the rod from the pinched area onto a 100 mm long square pyramid with a pointed top. To do this, place the workpiece on the anvil horn and apply several quick and strong blows, turning the rod 90 degrees. While the part is still warm, trim the edges on the flat surface of the anvil.

On the edges of the pyramid, use a chisel to knock out several notches at an angle of 45 degrees. According to this hook...

- one of those areas where large production capacities and technological equipment are not needed to organize a profitable business. At the same time, the product is in demand in the construction market, the scope of application is huge and this simple product does not need advertising.

Nails are one of the most used types of fasteners, so it’s difficult to stay here without a buyer.

Nails as a product are a very simple subject, especially when it comes to their most common types - round construction nails, wallpaper nails, and so on. Manufacturing is a more complex process; it will require special equipment and a more complex production line.

For most types of products, the production technology turns out to be very similar.

• The basis for them is wire of different sections and from different materials. The wire is offered in spools, so the first stage of production consists of unwinding and straightening the material.
• Then the wire goes to a roller straightening device - these are 2 teeth fixed into mandrels. The chisels grab the wire and push it into the impact structure of the nailing machine.
• The nailing machine cuts blanks to specified sizes. To do this, the wire is inserted into the impact device until it stops, clamped and cut off. During the reverse movement, the workpiece is released and held by the sleeve. A cap will be formed on the workpiece in place of the cut fragment. The impact device returns to its original position.
• Formation of the cap, production of notches and points - the heads are obtained using 2 semicircular disks with grooves. When formed, the clamping device secures the discs so that the grooves face each other, forming a round hole. Due to this, notches are formed on the head. The sharp end of the nail with a point angle of no more than 40 degrees is formed automatically due to the design of the pliers.
• Finished products are dumped into a bunker, sent to a warehouse and packaged.

The production of different types excludes some operations - for example, a machine nail does not have a point, or includes additional ones - applying a protective layer of zinc, copper, brass, but the general technological scheme remains unchanged.

The video below discusses the nail production technology:

What you will need

To manufacture products you will need premises, raw materials and a production base. All 3 components are quite accessible, since the production process does not require any special conditions - pressure, humidity, or complex technological operations.

Raw materials

The vast majority of nails are made from low-carbon steel grade St. 1, Art. 2, Art. 3, Art. 5, Art. 10, Art. 15. The material is manufactured at any metal rolling plant and is regulated by GOST 3283-74 wire parameters. Wire is supplied in reels weighing from 0.7 to 1.8 tons. The latter is important not only for the cost of the material, but also for the equipment: if the reel weighs heavily, you will have to purchase a more solid unwinding machine.

The price varies quite widely - from 24 to 35 thousand rubles. per ton, as it is determined by the nature of the material and the diameter of the wire for the production of nails.

• For example, you can use ordinary steel wire for manufacturing, and then coat the finished products with zinc. You can do otherwise and purchase galvanized wire. In this case, the raw materials will be more expensive, but due to the absence of such an energy-intensive stage as galvanizing, the production itself will be cheaper. The choice here depends on the supplier.
• For production you will need high-carbon steel that has undergone heat treatment. This type of raw material is much more expensive, and the production of nails is not cheap. Conventional hardened nails are just a by-product, as their scope of application is limited.

Control of raw materials is very important. It is necessary to organize a check not only of the weight of the reel, but also of the characteristics of the wire: color, steel grade, etc.

Another nuance is the container. As a rule, finished nails are packaged in cardboard boxes, and the products are poured into boxes at the last stage of production.

We’ll talk about the equipment for producing nails and its price below.

Equipment

A mini-shop for the production of nails can be opened even in an ordinary garage, the corresponding equipment is so compact. The simplest production line consists of 2 modules.

• Telfer– a device for unwinding a bobbin. The simplest manual device with a lifting capacity of up to 2 tons costs about 20 thousand rubles. and is considered sufficient for small production. Automatic will cost more.
• Wire nailing machine or machine (or mini nail machine)– a wide variety of devices, manual and multifunctional, are produced. Here the choice depends on the volume of expected production and the type of nails. To avoid making mistakes when considering options, consider the following factors:
  • power – ranges from 3 to 20 kW, which is decisive for the volume of finished products;
  • the ability to produce nails of different lengths - from 12 to 32 mm;
  • ability to work with wire of different diameters - from 1.2 to 9 mm. This option significantly expands the range;
  • production speed – on average ranges from 100 to 600 products per minute;
  • adjusting the diameter of the head allows you to produce different types of nails - construction nails, and so on;
  • weight – this matters when choosing a room. A device weighing 0.7 tons can be placed in a garage, but a device weighing 2 tons will require a solid concrete foundation.
• Thread rolling machine appears on the line if a different kind of release is expected. The device is controlled by a controller and carries out knurling according to the specified parameters.

A special module will also be required if the finished products are coated with an additional layer - brass, copper, zinc. When production volumes are large enough, it turns out to be more profitable to galvanize products on site than to use ready-made wire.

The price of a nail production machine depends on all of the above factors, as well as on the country of origin. Taiwanese products are considered optimal today. The price range is very wide - from 350 thousand rubles. up to 900 thousand rubles Used equipment can be purchased at a much lower price - from 120 thousand rubles. You can also try to make a machine for making nails with your own hands.

Now you know how much a machine for producing nails costs, then you will find a business plan model for production, which, according to reviews, is the most acceptable.

This video will tell you what it is nail making machine:

Manufacturing as a business

Judging by reviews from manufacturers in this area, the complexity of organizing an enterprise is average. Most of the difficulties are not related to the equipment and installation of the industrial line itself, but to documentation and registration. The latter is mandatory, since wholesale buyers do not agree to cooperate with enterprises that are not registered.

Necessary

Setting up a business will require a fairly simple sequence of actions.

• Product Selection – There are many types of nails, and to develop a plan it is important to know which products you intend to produce. The nature of the raw materials, the power of the machine, and the capabilities of the technological line for the production of nails depend on this.
• Registration of a form of management - there is little choice here: a private entrepreneur or a limited liability company. You also need to choose a taxation system. The most common choice is the simplified tax system, that is, 15% of the profit. In this matter, you will need to consult a lawyer.
• Choosing a room - the requirements for it are minimal. For placement and maintenance of 1 nailing machine it will require 15–20 sq. m. The second condition is high-quality electrical wiring. Most devices require a 380 V network to operate. Additional space is also needed for storing raw materials and storing products.
• Purchase of equipment corresponding to the project.
• Hiring personnel – one trained person is enough to operate the machine. Preference is given to physically strong people: such work requires physical effort.
• Searching for buyers - the best option is wholesale buyers, especially permanent ones: construction companies, hardware stores, wholesale centers, furniture manufacturing enterprises, and so on. The search is carried out using different methods: from advertising in the media to “cold calls”.

Payback

The profitability of the nail production business is determined by the demand for products in a given region and the cost of raw materials. Despite the average occupancy of the market, competition here is quite high.

The initial estimate includes the following costs:

• the cost of equipment depends on the power and functionality of the devices, their quantity and variety of assortments. You can reduce costs by purchasing used machines. On average, the figure will be 400–550 thousand rubles;
• rental of premises - depends on the region, but, as a rule, fits into 15 thousand rubles. per month;
• purchase of raw materials – including containers. The amount depends on the nature of the material, usually 25–35 thousand rubles. per ton;
• business registration;
• payment for staff work.

The average payback period is 6 months. In practice, everything depends on established sales. Provided that all products are sold and the workshop productivity is 4.0–4.5 tons per month, the initial costs can be recouped in a year, which means the profitability of the enterprise will be 29%.

The production of nails is a fairly promising option for small and medium-sized businesses, since this type of fastener is always in demand on the market. However, the success of an enterprise is determined not only by the type of product, but also by demand in the region and the cost of raw materials.

A business plan for the production of nails is discussed in this video:

The smart nails puzzle is a classic one, consisting of two identical nails.

The gap where the nails intersect is wider than the thickness of the nails themselves, so the nails can be connected to each other as well as separated without the use of force.

The apparent simplicity of this puzzle is what makes it great, and the solution to the puzzle is not as obvious as it seems at first glance.

This tutorial will show you how to shape the nails into the correct shape and, of course, how to solve the puzzle itself.

Step 1: Bending Machine

The secret to creating this puzzle is understanding how to make 2 nails in the correct shape.

The simplest way is to create a bending device, which consists of two 7.5 centimeter metal rods and a wooden block. The rods can be made from two bolts by tightening them in a vice and cutting off the heads and threaded parts. The sharp edges remaining after the cut must be carefully sanded.

Using a 0.8cm bit, I drilled two holes in the piece of wood about 2.5cm apart. One hole was about 2.5cm deeper than the other - this is important.

Step 2: Clamp the bending machine in a vice

Metal rods need to be driven into the holes, and a wooden block must be tightened in a vice.

You can create a device like this using a variety of materials and tools - the idea is that you need two strong poles mounted close to each other on a fixed base.

Step 3: Nails

I tried different nails, but the ones I liked the most were the 16D 3 1/2″ standard nails. Try making puzzles using several types of nails, or you can also make them with wire, to find the perfect one.

If the nails are coated with anti-corrosion grease, it is better to wipe them off, otherwise, by the time you finish the job, all this grease will end up on your hands.

Step 4: Bend the nails

Holding the nail firmly in the pliers, place it between the rods as shown in the picture and bend the nail around the longer rod.

It may take a few tries to get good results, but after a couple of bent nails you'll get the hang of it.

Step 5: Almost done

The nails should look like this.

Step 6: Clearance

The key is to get the correct gap where the nail crosses itself.

The gap should be slightly wider than the thickness of the nail itself.

If necessary, carefully tap the bent nail with a hammer until an identical nail cannot fit through the gap.

Step 7: Do more and more...

Obviously, you need two nails for one puzzle. But I recommend making a lot of puzzles simply because it will be a great gift for those people you come into contact with.

Step 8: How to Solve the Puzzle

First you need to put the nails together. The process is the reverse of how to separate them. The solution is in the second and third pictures - the movement requires a lot of rotation. The two nails should wrap around the midpoint where they touch.

Just play with them and apply a little force at different angles and you'll get the hang of it.

But, everything is not as simple as it seems, and for the joy of solving, I highly recommend following the photos just to collect the nails. And try to disconnect without peeking.

Bent Nails is a classic DIY puzzle that should delight you and anyone you give it to.

To get a decent profit, it is not at all necessary to organize a technically complex production with large capacities and high-tech equipment. There are also areas of activity that do not require large capital investments from the entrepreneur, but with products that are in great demand on the market. Without a doubt, we will include this as a nail manufacturing workshop. If you buy a machine for producing good quality nails, you can start a business literally at home. Fastening materials do not require advertising, the sales market is huge, the technology is extremely simple, the devices are relatively inexpensive - all this makes this line of business very promising.

Our business assessment:

Starting investment – ​​400,000 rubles.

Market saturation is average.

The difficulty of starting a business is 5/10.

What nuances does a businessman need to think through before opening a mini production of nails in Russia? Despite the fact that a small workshop is planned, there is a lot of work ahead.

Registration of a future enterprise

It is unlikely that any wholesale client will cooperate with a company that is not officially registered. Therefore, first of all, we set off to officially register our workshop. The IP form may well be suitable for a mini-factory.

Due to lack of time, the collection of documents and permits can be entrusted to a qualified lawyer.

GOST does not impose any special requirements for organizing a workshop for the production of fasteners, and therefore it should not take a lot of time and money to collect the necessary documents.

Nail manufacturing technology

The production of nails as a business is especially good because the technological process of production is extremely simple. In addition, all stages are performed on special equipment. And this saves a lot of money for the entrepreneur, since there is no need to hire highly qualified personnel. If you wish, you can train workers to operate the machine yourself.

The technology for making nails is as follows:

• The wire unwinds from the reel and enters the machine.
• The wire is cut in accordance with the specified parameters.
• At the other end, through a blow, a cap is formed.

The technology may differ slightly depending on what product is planned to be produced. For example, the production of galvanized nails implies the presence of one more stage - galvanization. But it can also be omitted, since it is possible to immediately purchase ready-to-use raw materials - galvanized wire. And this is sometimes more economically profitable, because it does not require additional equipment in the workshop.

Purchase of quality raw materials

Having understood all the nuances of the technology, you can begin to search for suppliers of raw materials. And this is a very important stage in organizing a business, since the quality of the finished product will depend on the quality of the raw materials. And the main component here is steel wire. Wire for the production of nails is usually supplied to workshops in the form of large coils of 500 kg each. There are also larger spools weighing up to 1.8 tons. And the exact form in which to purchase the wire will depend on the equipment purchased, since not every machine can “handle” the large weight of the skein.

The cost of the wire will depend on its type and the pricing policy of the specific supplier. On average, the price range ranges from 25,000 rubles. up to 35,000 rub. per ton.

In order for a nail production plant to produce only high-quality products, it is important to organize careful incoming control of raw materials at the enterprise. Here the compliance of the actual parameters (skein weight, color, brand) of the wire with those specified in the accompanying documentation is monitored. And good raw materials will not only be the key to producing a high-quality product, but will also save equipment from premature wear.

In addition to wire, the workshop needs to arrange supplies of wooden containers - boxes. Finished products will be poured here during the manufacturing process. And right in these boxes, finished products can be supplied to wholesale customers.

Workshop technical equipment

There should not be any problems with the technical equipment of the workshop, since there are a lot of offers for equipment on the market today - from the cheapest manual machines to entire production lines. And how much a mini machine for making nails with your own hands costs will depend on the power of the device, brand, configuration and degree of automation.

An entrepreneur can choose machines of both foreign and domestic production. And it is impossible to say unequivocally which option is better here, since in terms of the technical component they are very similar. The main difference is the price. But is it worth overpaying for foreign devices if they work with the same raw materials and the same technology?

Automatic machine for the production of nails

Since almost every nail production line is equipped in the same way, when choosing suitable machines it is better to pay attention to their individual characteristics:

• The speed of obtaining the finished product is of great importance.
• It’s good if the machine can work with wire of different diameters - 1.2-2 mm.
• Obtaining nails with different shaft lengths (15-60 mm) will expand the range of products.
• If it is possible to adjust the diameter of the nail head, it will be possible to obtain products for various purposes.

The issue of the cost of technical equipment in many cases will be decisive in the choice. And this business is also good because the price of equipment for the production of nails varies over a wide range. Completely manual equipment, which can easily fit in an ordinary garage, will cost the entrepreneur no more than 400,000 rubles. But if we talk about more powerful machines, then for such equipment you will have to pay much more - up to 1,000,000 rubles. For example, the AG4116 machine, which is popular today with average productivity, costs ≈700,000 rubles.

And if the available money is not enough for even the cheapest equipment, then you can think about purchasing used equipment for the production of nails. This will save you a lot of money - practically new devices can be bought 2-3 times cheaper.

Modern automatic nail release machines are very easy to operate, and therefore you can start a business even without outside help - with small volumes of production, even one person can handle servicing the equipment.

Taking into account the fact that in the process of manufacturing finished products, huge spools of wire are used, it is advisable to supplement the automatic nail production machine with an electric or manual forklift. This equipment will greatly facilitate the process. A manual lever hoist (with a load capacity of up to 2 tons) can be bought for about 20,000 rubles. – it will be quite enough for a small workshop.

Problems of selling finished products

It’s great if, even at the stage of business planning, an entrepreneur evaluates the competition in the regional sales market. This will help in the future to plan the enterprise development strategy and customer search plan.

As in many other manufacturing areas, in this niche we rely on wholesale buyers. Even a low-power machine will produce large volumes of products that private individuals simply will not buy up.

It is absolutely clear that the price of a machine for producing nails will pay off the faster the sooner contracts for the supply of finished products are concluded. Potential wholesale consumers:

• furniture factories,
• construction companies,
• construction bases and shops.

Surely, large companies are already cooperating with someone, which means that it will not be easy to win them over to your side, only if you reduce the price of the product. And let the entrepreneur lose a little profit here, but this will allow him to immediately ship the manufactured products. With the development of the workshop, prices for products can be raised, covering new markets.

Since our target is wholesalers, there is no point in launching a large-scale advertising campaign. But you can still make yourself known - advertisements in newspapers and the Internet, articles in specialized magazines.

How profitable is the nail making business?

Every business plan for the production of nails, even if we are talking about organizing a home business, must contain a section proving the profitability of the planned workshop.

But before we talk about profits, it is necessary to calculate capital costs. And here everything depends on specific conditions - the cost of equipment, the availability of production premises, the terms of the contract for the supply of raw materials. On average, 1,000,000 rubles will be enough to organize a full-fledged workshop.

This will include the following expense items:

• Purchase of medium power machines (≈350pcs/min) and their commissioning.
• Rent a small room.
• Providing a raw material base.
• Official registration of the workshop.

But if you purchase used equipment and install it in your own garage, then the entrance ticket to this niche will cost no more than 400,000 rubles.

Practice shows that the production and sale of nails with established distribution channels can bring a consistently high income to an entrepreneur. But it is impossible to indicate an exact figure for income, since everything here is strictly individual. And to understand how profitable this area is for an entrepreneur, you can take the following profitability indicators as a basis: the cost of a ton of products is ≈30,000-38,000 rubles, the selling price of nails ranges from 40,000-45,000 rubles/t.

Making nails is one of the most cost-effective manufacturing processes. For a full operating cycle, you will need special equipment and several additional accessories. An important step is to become familiar with the specific design of the nailing machine and the principle of its operation.

Description of the nail structure

Modern nailing is a complex production complex that is designed to perform several types of operations. Because of this, making it yourself will be very problematic.

The main manufacturing material is wire made of steel, copper or brass. It is supplied in coils, so before production begins it is necessary to carry out its processing - unwinding and straightening. Then you can start producing finished products.

Stages of nail production using a special machine.

1. Installation of wire into the gripping mechanism of the equipment.
2. Pulling the workpiece, as a result of which it is leveled.
3. Forming the nail head. Screw-cutting heads are used to fix the workpiece. The wire end is deformed using an impact mechanism. As a result of this, flattening and formation of the cap are performed.
4. The workpiece is pulled to a specified length. A pair of cutters cut on both sides, thereby forming the sharp end of the nail.

This is a general description of the production process using a nailing machine. Despite the slight difference in the layout of equipment models, the production process technology remains unchanged.

In order to optimize the cost of purchasing equipment, you can make an unwinding device yourself. It is a conical metal structure mounted on a vertical support post.

List of main technical characteristics

The next step is to determine the required technical and operational qualities of the machine. The defining indicator of nailing equipment is its productivity, i.e. speed of production of finished products by the machine. But in addition to this, a number of other factors should be taken into account.

The drive of all moving mechanisms is often carried out through cam units. They are connected to the electric motor. The speed of operations, as well as the maximum diameter of the steel workpiece, depends on it. Setting up the equipment is carried out by adjusting the wire feed units, setting the force of the impact mechanism to form the nail head. In this way, you can set the operating frequency of all machine mechanisms.

Main technical characteristics of equipment for making nails:

• maximum and minimum diameter of the rod;
• limits for changing the length of the workpiece;
• performance;
• weight and dimensions of equipment;
• power consumption of the electric motor.

The diameter of the finished nail head depends on the cross-section of the wire. The impact mechanism has a standard size. During the production process, you can only change the amount of force exerted on the workpiece.

The advantage of modern nail production machines is the almost complete automation of their operation. It is important to correctly configure the primary parameters and timely feed the wire into the gripping unit of the machine.

Optional equipment

In addition to the above, it is recommended to purchase several additional units for the production installation to optimize the production process. They are designed for subsequent processing of nails and their packaging.

The wire used has a protective layer of lubricant that prevents it from rusting during storage. However, this gives the finished product a non-marketable appearance. Therefore, for final processing of nails, it is recommended to purchase or make your own industrial rotating drum.

It is a container installed on a supporting structure. On one side the drive from an electric motor is connected. The drum is filled with a small amount of caustic soda and ready-made nails. During the rotation process, the surface of the products is cleaned. After this treatment, the nails are completely ready for packaging.

Additionally, you can buy a filling machine. With its help, even at the production stage, you can make packaging of finished products for further storage or sale. You must first purchase containers for packaging the finished product.
