Quite often, twisted pipes can be found in various applications. What are they for, what is the process of their manufacture? These products are mainly used as decorative items. Moreover, they do not always perform the function of a specific conductor of any liquid. Let us consider in more detail the scope of pipes, as well as the features of their production, the ability to do the work with your own hands and how the home-made material will look like, whether it is worth spending additional effort and money on the manufacture of the machine.

Application

The machine for making twisted pipes is a useful thing in various fields. For example, it can be used in the manufacture of furniture, oddly enough. This is because twisted pipes can be used as structural elements of various furniture options. Modern furniture production technologies are a non-standard approach and the use of high-quality and reliable materials. Twisted pipes in the furniture industry can be found as elements of:

tables;
chairs;
legs of upholstered furniture;
bar counters;
shelves;
beds;
shelving.

Having a small production of furniture, a twisted pipe machine can give a new round in production: push for fresh ideas, expand the product range.

Another industry where twisted pipes can often be found is construction, or rather, the design of the exterior and interior of a building. In the first case, supports for a canopy, porch railings, railings for stairs, balcony racks and much more can be made from a twisted pipe, in the second case, pipes have also found application. They can form a composition for a decorative addition to the design, for example, as a stand for flowerpots. The twisted pipe machine will be useful in the production of stairs, structural decorative and functional elements of buildings. It can also be used in the production of awnings, gazebos.

In some cases, heated towel rails are made from a twisted pipe. Due to the fact that the pipe is made of metal, it can be used as a cavity for filling with hot liquid, water or oil. A twisted shape will create a more original appearance. Moreover, such pipes can be coated with a special heat-resistant paint - this will provide additional solutions for decorating the bathroom.

Machine manufacturing

To make a machine for a twisted pipe with your own hands, you need some engineering and technical knowledge. The main thing in do-it-yourself production will be the correct drawing up of drawings. Only correctly calculated and executed drawings will give all the necessary parameters for the production of precision equipment. However, if there is no time, effort and special need for serious brainstorming, it is quite possible to buy this machine. Despite its considerable cost, it quickly pays off. Although, of course, it would be more practical to take it as an addition to an existing production line, and not as an independent device.

Usage

The most important thing in the operation of a machine for the production of twisted pipes can be called ease of use. If serious calculations, drawings and a lot of time are needed to create such a device, then it is enough to watch the video once or twice or use photo instructions to use it.

The principle of operation lies in the special rolling of the pipe layer, without cutting the entire metal. During preparation, the operator sets the position of the sliders according to the adjustment nanogram. The position comes with a clear correspondence with the thickness of the material. You can use products with a diameter of 1-15 cm. After that, it is important to rotate the screws, making marks on the sliders. Installation takes place opposite the marks on the ruler, which is located on the working plate.

As soon as the preparatory work is completed, it is necessary to turn off the machine. The pipe can rotate clockwise. The knives create the necessary cuts without completely damaging the metal. The angle of elevation of the pipe coil will also depend on the device. The most common are angles of 35, 45, 55, 90 degrees. The productivity of the device is up to 120 m/h, but it depends on the model and manufacturer. Therefore, if this parameter is important, it is better to specify it separately and in advance when choosing a machine.

With a sufficient level of orders, the machine usually pays for itself in just a few days. Therefore, before buying, it is advisable to evaluate the amount of existing and subsequent work. Moreover, it is desirable to give an assessment of the most critical indicators. Then the issue of payback will not be affected.

Summing up, it is worth noting that such a machine is an auxiliary device. Although, if you get regular orders specifically for a twisted pipe, you can take more than one machine, specializing only in such production.

For a long time, people have learned to make elegantly shaped products from metal. These can be ornate lanterns, canopies, fireplace elements, wrought iron furniture, awnings and fences. Until recently, such products were created in the process of painstaking and complex work of a blacksmith.

To date, modern equipment has appeared on the market, with which you can create forged structures without heating the metal. The advantage of manual cold forging is that now it is not necessary to master any complex technology and make physical efforts to work with metal. It will be enough to know how the equipment works and how to use it correctly.

Varieties of equipment for manual cold forging of metal

Most often, for the manufacture of forged products, machines, presses and other special devices are used.

With the help of various manual forging equipment, you can make separate decorative elements and assemble complex forged structures from them in the form of fences, gates, gates, etc.

Hand tools for forging. Price

For the manufacture of complex forged structures, professional equipment with an electric motor or hydraulics is used. The most affordable to use and at a price is a hand tool for cold forging, which can be bought in specialized stores.

Products are twisted in a section of 500 mm, however, the length can be increased independently. The price of such a device is 35,577 rubles.

Machine "Snail" do-it-yourself

Some home crafters make their own cold forging equipment. Using the drawings given on the Internet, you can quite easily assemble the Snail machine.

Necessary tools and metal parts:

First of all, a drawing of a spiral with three turns must be applied to a sheet of paper. After that, you need to check the dimensions so that a reinforced rod with a diameter of 10 mm is placed in the thread. Now you can start making the machine.

Plates are cut from a steel sheet with a grinder: 130x130 mm and 100x100 mm.
Next, the sections of three steel strips and a three-centimeter rod are cleaned with emery.
According to the template, with the help of pliers, the steel strips are bent so that three spirals of different lengths are obtained.
All elements of the machine are welded according to the scheme.
A steel pipe is welded at the bottom center of the tool.

Welding work must be performed with high quality, since it is on them that the life of the machine depends.

Conclusion

Despite the fact that the cost of machines with which metal is forged is rather big, some types of manual equipment are quite affordable. Those who have experience in such work and beginner blacksmiths can easily pick up an inexpensive version of the tool that will help create a forged product of a certain type.

In addition, some types of machine tools can be made independently.

Due to their beauty and sophistication, metal products made by forging have long become very popular. Such decorative elements are quite expensive and it is not always possible to order all the desired decorations for an interior or a country house. But, in addition to the hot type of forging, which is needed in order to create metal decorative structures, there is a cold version of it. The latter option can be implemented independently, for this you need to build a cold forging machine with your own hands, after which you can begin to implement all your ideas and ideas.

Types of machines

Basically, all devices that are designed for the manufacture of metal parts using cold forging are characterized by a manual drive. Few of them work on the principle of an electric drive, although it is possible to build such a structure with each of the devices. The only question regarding the drive is expediency, because the cost of the energy resource that feeds the unit and the complexity of the installation process of the mechanism may not justify itself if we correlate them with the amount of work performed and its regularity.

The table lists all the fixtures that are operated by a manual drive type related to the cold forging process.

Device	Short description
twister	With the help of such a device, the metal is twisted, spirals and curls with a narrow core are formed.
Torsion type machines	With the help of such a machine, screw-type rods are twisted, and it is also possible to manufacture large-sized spirals and filaments (baskets, lanterns and bulbs).
Inertial stamping machines	They are intended for making connecting parts with decorative components, making patterned tips and various small patterns and reliefs.
Bending machines	There are several varieties of such machines: pressure, broaching and combined types. The first variety is needed in order to get wavy bends or zigzag bend the rod. The lingering variety is in demand when it is necessary to make a ring, curl or spiral with a wide core. Using the combined variety, you can build any of the listed elements.

Reference: very often in some sources you can find the name of machines designed for torsion as well as for machines that make winding - twisters. However, this is not entirely true, machines that twist metal are torsion-type machines.

Differences of cold forging

There is such a thing as "stamping", which is sometimes confused with cold forging. Cold forging itself has 2 principles by which this process can occur. The table shows the process differences.

Process	Description
Stamping	The stamping process can be described as extruding certain shapes using a punch that works at a high level of pressure. An example of a stamping process is an aluminum can. The heating of the metal is not used. It is hardly possible to apply such technology at home, since it is impossible to create the necessary conditions for this.
Cold forging type (riveting)	This kind of cold forging, in fact, is hardening, namely, a certain number of blows of a very large force are carried out in the process, which allows the structure of the metal to change and become the required parameters in size and shape. Such manipulation is carried out with the help of a hammer, which can also be built with your own hands.
Cold forging type (bending)	Another variety is bending. With this technology, the metal structure remains the same, without changing its characteristics. This type of forging is possible for use at home, for it you just need to start creating a cold forging machine with your own hands.

Cold-type forging, which is carried out according to the principle of bending, is quite simple to do, especially if there is special equipment of a stationary type, which greatly facilitates the process. The advantage of this variety is that you can assemble almost any cold forging machine with your own hands without spending a lot of money on it.

Cold forging machines

Each device in order to be able to engage in cold forging has its own characteristics and parameters. In order to easily make a cold forging machine with your own hands, you need to figure out what each of them is.

Machine		Device
Bending machines		The design of this device is such that by changing the rollers and wedges, the size of the waves and bends changes. They can bend rods up to 16 mm. The only caveat of this device is that it cannot be made independently, because it requires processing and turning many parts of the exact size. The cost of such a device is low.
twister		The unit works thanks to equipping it with a special template, to which the processed piece of metal is pressed. The pressure must be very high, so those who work on the twister must have sufficient strength for this. In addition, the safety of the template itself is ensured by the presence of a persistent horn (terminal). As for the middle horn, which is otherwise called circumferential, it should be done in such a way that it can change its position and be fixed in it. The efficiency of work depends on this, especially for those who start the process for the first time.
Base with spacers		Such a unit will allow you to make patterns of absolutely any variations. The design itself is very simple and is a plate of durable and reliable material, into which spacers are screwed at a certain distance. For such purposes, bolts with sizes from m8 to m24 can be used. The thickness of the metal in this case depends only on the skill of the one who works on the machine. Basically, such a device is well suited for metal with a thickness of 6 mm.
Snails Loom-twister	with collar	Such an installation is a base plate on which there is a special coil. Such a coil is used as a template for a future product. The peculiarity of the machine is that the “snail” template is divided into several parts, which are fixed to each other with the help of special connecting elements, which allows the template to vary in shape during operation, which creates various kinds of waves and bends. There are also disadvantages in this design, because in order to make such a cold forging machine with your own hands, you need to select a very durable material that will not bend over time. Also think over the connecting loops, which are quite vulnerable, given the amount of force with which the entire process of bending the metal takes place.
	lever type	In this type of machine "snail" the template is attached very firmly to the base. Due to this fact, his performance is less, however, the reliability is greater. using a special lever, the metal plate is pressed against the template; at the same time, it is necessary to move the mobile roller in the process. To make such a cold forging machine with your own hands, you can use steel material, which is distinguished by its strength, and the roller can be made from a conventional roller bearing. In general, the design is similar to a pipe bender.
Torsion machine		Such a device will help well in the helical twisting of the rods. Such a machine is made from a cylindrical metal base and two fastening and simultaneously twisting elements. It is advisable to equip such a design with a special pair of paws that will not allow the metal being processed to bend inappropriately. The principle of operation on the machine is such that the rod is placed in the elements holding it, clamped at one end, and twisted at the other end with the help of a rotating spindle to the desired size of the helical wave.

Electrically driven torsion machine for cold forging

In order to improve not only the efficiency of the cold forging machine by twisting the rods into a helical wave, but also to increase the speed, as well as ensure stability and not be subject to overwork, an electric type drive can be installed.

Working by hand, it is quite difficult to make all the decoration elements from metal rods the same, since the uniformity of the torque in this situation will vary greatly. In order to avoid errors in the manufacture of products, you can use:

axle shaft from the car, which is installed on the drive axle;
you will also need a differential gear pair;
Use a cover for protection.

Of these devices, you can build an electric drive to the torsion bar. Such an engine is better not to exceed power ratings of 900 rpm and 3 kW.

Building a curl for the machine with your own hands

Before you start creating a machine for cold forging with your own hands, you need to be able to calculate the parameters of the template spiral, because there are practically no special programs for such purposes. Such a template should not only be technically literate, but also have an attractive appearance.

The calculation of such a template is based on a logarithmic spiral. Some of the nuances in the construction can be distinguished in the following list:

the beginning of the construction is taken at the point R0;
the turning radius will be equal to the fixed angle;
the indicator of the length of such an angle must be multiplied by the divergence of the coil;
the discrepancy in the standard version is basically taken equal to 1.2;
for ease of calculation, as well as maintaining accuracy, the bending angle is best taken at an angle of 45 degrees;
if there is a need to build a template that will have a denser spiral, then the 8th part (s) of a unit distance from the spiral should be added to the radius value;
as for r0, it must be equal in size to the size of the cross section of the diameter that the workpiece for the spiral has.

Important: r0 can take any value, it all depends on what characteristics the metal is used for the workpiece, namely, on its density.

Considering all the nuances, you can start making a “snail” template, for this it is best to be able to solve equations that have a cubic degree and higher. There is no exact formula for calculating such a device, but there is one that allows you to achieve the best result. The sequence when building a spiral pattern can be as follows:

the initial point r0 is determined first;
the turns that the template will have are taken arbitrarily, their number can be any;
using tabular data, you should calculate the diameter (b), while making sure that it is smaller in width in the opening for the template;
using the formula, the radius R is calculated;
the last step is to transfer all the obtained points in accordance with the scale, after which you can proceed directly to the construction. In the process, let's adjust using a similar formula to the radius R in the final version.

Reference: if it becomes necessary to calculate intermediate values, then this is done in accordance with the geometric proportion.

Construction of a cold forging machine

When drawing up a drawing for further creating a template for the machine, it is best to make sure that it has the maximum number of different variations regarding bends and waves. Having such blanks, it is possible to create a cold forging machine with a variety of interchangeable nozzles, which will make it possible to produce various patterns and monograms.

The sequence of actions when creating a device:

Initially, you need a metal sheet, the size of which will depend on the number of patterns placed on it. The templates themselves should be placed in such a way that there is room for the manufacture of products, because during the process the material from the nozzles may move due to lack of space. Also, if the templates are not sufficiently removed from each other, complications may arise in the work.
As for the variations of the templates themselves, they can be either simple or contain more than one turn of the monogram. You can make a similar snail of the share type and think over the design of the bends in the disassembled and assembled state. At the same time, you should be careful when choosing the material for fixing the sliding parts - it should be as strong as possible.
The change of nozzles can be ensured by making a rectangular slot, it will be possible to insert interchangeable forging templates into it. They should all be attached to metal plates having the shape of a rectangle. The fastening of such nozzles will be provided with the help of bolts.

Device assembly

This version of the machine is used as an example because of its simplicity. Knowing the basic principles and sequence of equipment design, it can be upgraded as desired. To assemble all parts of the equipment into a single whole, you will need to use:

drill with carbide type drills;
apparatus for welding;
a saw that cuts metal, or a hacksaw;
metal sheet of the selected size;
round metal pipe;
metal rod;
bearings of different sizes;
M8 bolts.

To assemble a cold forging machine with your own hands, you need to use a proven sequence of actions:

Conclusion

Those who decide to seriously engage in forging and make a cold forging machine with their own hands should be very scrupulous at the stage of creating drawings and calculations. Otherwise, the creation process is quite simple, and having understood the principle of equipment design, you can come up with various kinds of variations that will help improve products.

Hot stamping technology is used to obtain three-dimensional decorative images on flat and shaped surfaces of furniture boards made of solid wood, MDF, plywood or veneer. To implement this method on a baguette, moldings or frames in furniture production, a wood embossing machine is used.

Technology features

Compared to milling, embossing makes it faster and easier to reproduce carved, braided, braided or voluminous textures of expensive woods on cheaper panels.

Hot pressing is more of a thermal molding of wood. Under the influence of temperature, the natural polymers contained in wood become soft and elastic.

How wood hot stamping machine works

Relief rolling is carried out on embossing machines. A heated roller with an engraved pattern is rolled over the surface of the workpiece and applies a relief image. The pattern can be applied to a flat surface and radius elements.

Design features

The main element is the unit for embossing flat and radius blanks. The hot embossed roller is mounted on the machine support spindle.
The shaft is heated by electrical resistance or by gas burners. The roller is placed in a closed casing and fixed on the bearing column. A thermostat and a temperature sensor are designed to maintain a constant temperature.
The water-type cooling system ensures safe operation without bearing jamming due to overheating during long-term use.
The efficiency of applying the pattern is emphasized by the finish. After applying coatings and patina, the drawing decorates profiles and baguettes very beautifully, giving them sophistication and originality.

KAMI offers a wide range of baguette finishing machines – you can buy machines for hot stamping, paste and primer application at an affordable price.

Today, artificial stone is a very popular building material. It is widely used both for cladding the facade of houses, and for laying out paths in areas, creating tiles and even fence elements.

The variety of colors, greater strength and lower price make this material more affordable and more popular among both professionals and people who simply planned repairs. Due to the fact that the price of equipment for the production of decorative stone is quite affordable, the technologies are not secret, the production of artificial stone can be an excellent business development.

The stone of own production will turn out cheaper than the purchased one, and the owner can choose and improve the texture and quality on his own. All that is needed is to understand the details: what material and how much to buy, what molds are needed for the production of decorative stone, to purchase a convenient production room and the entire set of required equipment.

Production room

Like any other, the stone manufacturing process requires compliance with certain technical and thermal conditions.

So the area of the main production facility can be from fifty to one hundred square meters.

There must be a warehouse for storing raw materials separately from the workshop.

The temperature in the room should not exceed 25 degrees. Heating can only be carried out in the production workshop. Lighting should be both general and local in those places where machines for the production of decorative stone are located. It is necessary to carry out plumbing in the room and equip the sewer drain. Be sure to install a high-quality ventilation system to ventilate the workshop.

Necessary equipment

When the premises are ready and equipped in compliance with all safety standards, the next step is to choose what equipment will be needed for the production of decorative stone. The following devices are often used:

Vibrating table (cost from 50,000 to 70,000 rubles).
Concrete mixer (5,000 - 13,000 rubles).
Electronic scales (15,000 - 25,000 rubles).
Multiple desktops.
Tanks for bulk materials.
Construction mixer (2,500 - 5,000 rubles).
Stone molds that you can buy or make yourself.
Pallets for molds.
Various small tools such as shovels, shovels, wheelbarrows, trowels, etc.

The vibrating table is needed in order to remove air bubbles from the solution using vibration. You can buy such a table or make it yourself according to the drawings and separately purchase a vibration motor to move the table.

Polyurethane molds can also be made by yourself, which saves money at the beginning of production. But the quality of the form itself directly affects the properties of the product, its durability and aesthetics. Therefore, it is better not to save on the quality of polyurethane. Experts advise using the product of German and American manufacturers.

Raw material

It is important to decide on the material from which the stone will be made: gypsum or concrete, and then purchase all the necessary mixtures. You may need:

The cement is white and grey.
Sand (river or quartz).
Pigment and dye.
Plasticizers for gypsum and concrete.
Gypsum, gypsum polymer.
Chemical mixtures.
Fiberglass.

Artificial stone can be painted in various colors. To do this, use a compressor with spray nozzles and an airbrush. You can also use brushes of various shapes to achieve the desired texture and color. The pigment can be added both to the finished stone surface and to the mixture itself.

Finished products

Purchased equipment for the production of decorative stone can be used for personal needs or for the manufacture of products for sale. It is advisable to pack the finished stone in order to protect it from damage during transportation and storage in warehouses. It is better to pack in cardboard boxes, laying the stone in layers. Each layer must be separated with a layer of cardboard or packaging film.

Production technology

Decorative stone can be made in several ways. The most common are vibrocasting and vibrocompression. Both methods are good in their own way and have a number of special advantages.

It is cheaper to manufacture equipment for the production of decorative stone by vibrocasting than to purchase a vibropress. This technique is easier to work with and set up. Manufacturing in this way will retain more moisture in the product, since there is no need to steam the stone; as a result, the finished product turns out to be more saturated coloring. The vibrocasting process takes place in several stages:

Preparation of a mixture of cement, pigments, modifiers and mineral fillers. The solution can be kneaded both with a manual construction mixer and with a special concrete mixer.
Pouring the solution into ready-made molds mounted on a vibrating table. The product must be in shape for at least 48 hours.
Separation of the product from the mold, removal of chips, packaging of the finished material.

The vibropress, in turn, makes it possible to produce material that is less expensive at cost. This process can be almost completely mechanized, which will increase productivity. Thanks to this choice, the future owner of the production can decide for himself which technology will be used depending on the expected performance.
