Drawings of someone who assembled a mill for corrugated sheets himself. Inexpensive and high-quality machines for corrugated sheets

The equipment necessary for the production of corrugated sheets is divided into three main groups:

• Manual machine for the production of corrugated sheets;
• Automated and semi-automatic production lines;
• Mobile equipment.

In the second case, all technological operations are performed with minimal participation of technological personnel or completely without requiring human participation.

Automatic and semi-automatic lines are also available in mobile versions. Such machines are convenient to use in the construction of modular buildings or arched structures at remote construction sites, when the cost of delivering finished profiled sheets is very high.

Example of a manual machine for corrugated sheeting

Finally, manual machine for the production of corrugated sheets it is driven by human muscular power. Typically, such machines are used for the manufacture of small products or various additional elements. This machine is extremely easy to use and it is on this that we will discuss in detail further.

Manual machine for corrugated sheeting - what are the advantages of such a solution?

Currently, many machine-building enterprises produce such equipment, and anyone can buy a manual machine for corrugated sheeting. Its main advantage is that such a machine does not require external sources energy, since human physical strength is enough to activate it.

In order to set up the production of profiled sheets on a manual machine in a matter of hours, you only need small room(although even this is not necessary, just a regular canopy is enough) and two workers familiar with the structure of the machine.

A manual machine for making corrugated sheets is indispensable for a small construction company, which is often faced with the need to use a small number of products from profiled sheets. It is simply not practical to order them because the cost of delivery to the site is too high.

Using this machine you can produce directly on construction site and various additional elements, necessary, for example, when installing a roof. A manual machine for the production of corrugated sheets is so simple that it requires virtually no maintenance other than periodic lubrication.

The advantages of such a machine include its relatively low cost. A manual machine for corrugated sheets, the price of which is about 2000 US dollars, will pay for itself after producing 750-800 m² of profiled sheets, which is approximately its daily productivity. And this does not take into account the cost of delivering this corrugated sheet to the construction site if it is purchased. But you can also buy a machine that has already been used. It will cost several times less, and will last for many more years, since the forces acting on its main components are negligible and their wear is minimal.

Disadvantages of a manual machine for corrugated sheets

A manual machine for the production of corrugated sheets also has some disadvantages. First of all, this is the short length of the resulting corrugated sheet. It is usually 2.0-2.5 m. When large sizes working plate, uneven bending of the profile in the form of an arc is possible, which occurs due to different compression forces in different parts of the pressure lip.

In addition, it is worth noting that on a manual machine for corrugated sheets it is possible to produce only one brand of corrugated sheet. However, machines with a replaceable matrix are now being produced, which makes it possible to produce corrugated sheets with various shapes and the height of the trapezoid. In this case, the bending dies must be replaced manually.

And the most main drawback is that using a manual machine you can produce profiled sheets only from galvanized steel. When deformed, the polymer coating of the metal may become covered with small cracks, which will subsequently lead to premature corrosion of the corrugated sheet.

This problem is solved using special modern manual machines for processing thin sheet steel with polymer coating. However, they are significantly more expensive standard options. In addition, galvanized profiled sheets can be painted. Wherein modern technologies applying paint and varnish coatings, such as, for example, powder painting, creates a decorative and protective layer that is in no way inferior, and maybe even superior in quality, to a polymer protective and decorative coating.

Design and principle of operation of a manual machine for making corrugated sheets

The manual machine for profiled sheets consists of three main units.

The main working body is a bending mechanism installed on a special frame. The bending mechanism itself, in turn, consists of hinges and gears that can be rotated using manual levers, as well as a replaceable bending matrix and a pressure beam.

In addition, each manual loom has a feed (back) table. A sheet steel blank is placed on it, which is moved to in the necessary direction and “tucked” into the bending mechanism. A special roller knife is also installed here, usually included with the machine. It is made from high-strength steel, the quality of which allows cutting 25 km of steel with a thickness of 0.5 mm. If necessary, the knife can be sharpened or replaced.

Finally, one more element is absolutely necessary - a receiving table with special stops. They can be customized depending on the specified dimensions of the profiled sheet that needs to be produced. A plate is also installed here, with the help of which the required bending angle is set and the steel sheet is fixed.

The entire process of manufacturing profiled sheets on such a machine consists of the following steps:

1. The steel sheet is placed on the table and fixed with a special clamp.
2. Using a matrix, a steel beam forms a trapezoid or wave profile (the bending force is adjusted depending on the thickness of the metal of the workpiece).
3. Mechanical control sensors stop metal bending at the right moment.
4. The travel of the traverse and the bending angle of the metal are controlled using a special scale.
5. After bending, the steel roll is unwinded and the process is repeated again from steps 1 to 5.
6. Once the required length is reached, the steel is cut with a special guillotine knife.

Design cam mechanism manual drive provides the ability to work with one hand. The presence of a roller knife and the installation of an unwinder make it possible to use rolled thin-sheet steel without preliminary cutting.

Today, corrugated sheets are increasingly popular among those who build modern buildings, erects fences, reliably strengthens partitions, and renews the appearance of old buildings. Also, with profiled steel, wide possibilities for construction become available. original roof residential building or office building. Thanks to high quality Rolled steel sheets can be used during the construction of structures such as warehouses and hangars.

Sheets of corrugated sheets can be used as a material for the following purposes:
walling different types structures;
roofing for buildings for various purposes;
production of formwork;
installation of partitions and fences.

How to prepare supports and table for feeding workpieces

Next you need to start assembling the table, along the surface of which the workpiece will be fed into the machine. The table should have a length that is several times the length of the finished product. There must be enough free space on the surface to accept the finished product. Optimal material table surface – aluminum sheet.

How to install rolling shafts and run the device

We do not tighten all the bolts to full strength - now our homemade manual machine for making corrugated sheets can be used for the first running-in of the material. If the corrugated sheet produced by the machine has the required shape, we fix the parts in place and tighten all the bolts firmly. If the shape of the corrugated sheet does not meet our requirements, we adjust certain details and repeat the procedure.

It must be remembered that a machine for producing corrugated sheets is equipment that is dangerous to operate. This machine is equipped big amount cutting and piercing elements, which, if safety precautions are not followed, can cause injury to the operator. Therefore, it is allowed to work on the machine only in protective clothing and safety glasses.

Corrugated sheeting is the most versatile and modern covering. Today you can easily make corrugated sheeting for a facade or roof. Our article will tell you about the installation of profiled sheets and the technologies for producing the material.

Corrugated sheets can be used as:

Production stages profile sheets:

• project development taking into account parameters;
• production on rolling equipment;
• transportation and delivery of products.

Requirements and production of material

Metallic profile for roofing is made from steel using the cold method. Corrugated sheets come in both protective coating(polymer, enamel), and without it.

Each type of corrugated sheet has its own thickness. When using high-quality raw materials (for example, steel), the material is produced with a zinc coating of 26 microns.

If the thickness of the coating is reduced by half, then wear of the material increases. Therefore, it is very important to use both first-class raw materials and high quality equipment.

Requirements for designing the production of corrugated sheets:

• the presence of a concrete floor with a flat surface in production premises;
• use of equipment with a carrying capacity of more than five tons;
• the minimum room temperature should be 4 degrees;
• availability of special gates for unloading and loading finished material;
• availability of premises for storing steel coils;

Requirements for equipment placement:

• convenient location of machines for their unhindered maintenance and repair;
• installation of unwinding devices near raw material storage areas;
• if there is not enough space in the premises, place the warehouse in a neighboring building.

Technology and process of manufacturing profiled sheets

The first step is to draw up a design sketch and make mathematical calculations. After this, the color and thickness of the future material are selected.

Stages of corrugated sheet production:

1. Installation of rolled steel into the unwinding device of the machine.
2. Movement of corrugated sheeting along the machine to special scissors. They cut off the excess sheet.
3. Adjusting the length and number of sheets using the control panel.
4. Automatic rolling of steel sheets.
5. Their further cutting in accordance with previously established parameters.
6. Marking and packaging of finished sheets in film.

Rolling machines for the production of corrugated sheets

Production equipment includes in its structure a cold rolling method and a hot processing method metal sheets. The most common method is cold processing. It does not require complete heating of the raw material at the beginning of work.

Thanks to special lines, the material is rolled and cut. perhaps in the form of profiling, that is, the material takes on a profile shape.

Profiled sheets come in various modifications. The machine equipment is responsible for this. After the production of corrugated sheets, the type is determined.

In accordance with the stages of mechanization, the machine for metal profiles varies:

• automated equipment;
• manual machine for rolling corrugated sheets;
• removable and mobile equipment.

Mobile equipment is used for the production of arched corrugated sheets. It is advisable to produce such sheets directly on the construction site. Arched corrugated sheets are used in the construction of hangars, grain storage rooms or airfields.

Composition of the profile production line:

• roll unwinder;
• rolling mill for profile formation;
• guillotine-shaped scissors;
• receiving device;
• automation.

Equipment workflow stages:

1. Placing the galvanized sheet on a special unwinder;
2. Receipt of strip feedstock into a special machine for rolling corrugated sheets, which contains a certain number of pairs of stands. This affects the quality of the product.
3. After passing through the stands, the steel sheet acquires the previously planned geometry.

It is worth noting that today the demand for corrugated sheets is growing every year. Therefore, many experts believe that investments in the production of rolled steel quickly pay off. Big choice construction companies provides a wide range of similar services.

Your own machine for corrugated sheeting will help you not only make good material, for example, for suburban construction, but also start profitable business, however, for this you need to know many nuances.

Such a device is quite easy to make at home with your own hands, if you understand the principle of its operation.

Considering that almost no construction site today can be completed without this material, it is widely used in everyday life, and if you make your own machine, you can make goods for sale.

Corrugated sheeting is an extremely popular coating today. It is used as a picket fence, material for walls and roofs, and cladding material.

Moreover, such sheets are characterized by relatively low cost and ease of installation.

However, it is worth understanding that strict operational requirements, which need to be taken into account, especially if you make the material yourself on a homemade machine.

There are several types of corrugated sheets, in the manufacture of which various raw materials are used. For example, metal corrugated sheeting is very popular.

It is made from steel using the cold rolling method.

For structures that will be used outdoors, for example, for a picket fence, you can make sheets coated with an additional protective coating - enamel, polymers, fiber.

Each type of raw material gives its own sheet thickness.

In the case of steel, we can get high-quality corrugated sheeting, which can also be galvanized to increase strength and resistance to aggressive environments.

If you make sheets without any coating at all, the material will wear out faster. Therefore, we can say that not only the machine itself, but also the raw materials play a big role.

It is better to assemble a rolling machine for corrugated sheets indoors, where there is a flat concrete floor.

In this case, the temperature in the room also plays a big role: it must be heated, without sudden changes. We choose a temperature not lower than 4 degrees.

If you plan to constantly produce such material, then it is better to immediately prepare rooms for storing rolls, dry and warm.

Varieties of design and principle of operation

To make a device such as a machine with your own hands, you need to understand the operating principle of industrial models.

This approach will help compensate for many shortcomings by replacing parts with more affordable ones.

Any corrugated sheet is produced by cold rolling smooth sheet raw materials through special nozzles and shafts.

The end result is a corrugated sheet of a given shape, which can be used as a picket fence, a fence, or a wall.

Even at home, a machine for the production of corrugated sheets requires the purchase of high-quality raw materials. It is bought in rolls for ease of use.

Such rolls still need to be unrolled, and here everything depends on the thickness of the raw material.

If you initially aim to make subtle modifications to the corrugated sheeting, then there should be no problems - the sheets can be straightened by hand.

But if you need to produce fairly thick products, then you can’t do without a bending machine.

The machine for corrugated sheeting can be made in two types: manual and automated.

The first one has a simpler principle of operation, it is easy to do it yourself and the cost of the design will be more affordable.

However, here the feed and adjustment of the shaft is carried out independently using its own force.

It is almost impossible to construct an automatic device at home on your own. This is economically unprofitable and also extremely difficult.

It is noteworthy that difficulties arise in final stages rental

The fact is that the rolls have a decent length, so to get finished goods, which can immediately be used as a picket fence or a fence, you also need to provide a method for cutting the sheets.

Special guillotines can help here. These scissors are made of very well sharpened steel and are also equipped with protective boxes and mechanisms for safe operation.

The best option would be to buy ready-made blades, since they follow the shape of the finished sheet.

Also, a manual machine for the production of corrugated sheets, like an automated one, can be designed using both simultaneous and sequential profiling technology.

In the first case, corrugation is produced simultaneously on both sides of the sheet. In the second, you need to run the sheet twice on both sides.

Of course, you can make corrugation on only one surface, but such sheets are not suitable for all purposes.

For example, for a home picket fence it is better to make two sides.

There are also machines that work with the hot rolling method.

But they are not used at home, since it is initially necessary to heat the steel and pour it into a mold that practically melts.

Ready-made sheets are suitable for a picket fence, but are unlikely to be used as cladding or for building walls.

Step-by-step instructions for assembling the machine at home

The main difference between corrugated sheets and other metal sheets is the trapezoidal corrugation. It seems that it is impossible to make such material at home, but this is not so.

It is quite possible to make a machine for making corrugated sheets made by yourself using a sheet metal folding machine.

However, it is worth understanding that a home device will not always be able to help in the manufacture of products that are too thick.

Thus, the maximum thickness of galvanized steel that can be bent should not exceed 5 millimeters.

With such a device you can make not only sheets for picket fences, but also ridges, cornice strips, and so on.

First of all, the frame of the machine is assembled. He has small sizes, and also does not require complete closure of the walls.

It will be enough to make good supports and secure them to concrete floor using screws. Next, you need to prepare a table on which the sheet will be served.

Usually its length should be at least a couple of times greater than the expected length of the product, because there should still be room to receive the finished sheet. The table can be made from aluminum plywood.

The main thing here is to make a special bar that will allow you to secure the roll or raw material. It is pulled tightly to the table using bolts. The hand lever is secured in the same way.

It is needed to move sheets across the table and adjust the feed angle. For greater reliability, this design can be equipped with a control spring.

It is worth understanding that some parts need to be purchased ready-made. For example, rolling shafts. It is impossible to make them at home from available materials.

But you can order them - today this is not a problem, and the cost for home workshop will be very low.

They are fixed to the frame and brought to the lever. The shafts should be secured using brackets made from pieces of metal corners.

With this procedure, it is necessary to carry out preliminary assembly. The first running-in of corrugated sheets is also carried out on it. All bolts are not tightened to full strength, and sheets are fed extremely carefully.

It is necessary to be guided by the fact that during operation the shelf of the corner and the shelf of the frame must be on the same plane.

If you manage to give the corrugated sheet the desired shape, then all the parts can be secured. However, do not forget about safety precautions.

This is especially true if guillotines are installed.

The work should be done extremely carefully, without haste, even if you experienced master, since there is an increased chance of injury.

The mechanism of operation of the device is quite simple, which is why it is possible to make such a machine at home. First we place the sheet of metal on the table. It is fixed using paws or a bar.

You can also cover corrugated sheets with different compositions, but for this you need to equip a special table.

At all stages you must wear protective clothing, gloves, and use safety glasses.
