Device for repairing brake tubes. Rolling for brake pipes do it yourself

The horse is not iron. Although it is called pensioners, but the car is only partially consisting of steel. The rest is plastic, rubber, glass and non-ferrous metals, to which you need a special attitude. Today we will talk about how to properly handle copper and aluminum tubes, which the modern car is simply used.

Non-ferrous metal tubes in car systems

The radiators still do not touch, this is a separate topic. Interesting tubes that are responsible for the work of brake and fuel Systems car. Rotten brake tubes - this is a problem not only old soviet carsBut also newer foreign cars that drove on the roads, generously sprinkled with salt and any chemistry for several years. The tubes come into disrepair primarily due to the fact that they affect the aggressive chemical environment. In winter, we have under the wheels of this medium - full. With human road surface, salt comes from roads along with snow, and at our roads, it can go to the next winter.

Causes of breakdowns of brake tubes

But not only in this cause of wear of hermetic tubes. From salt, they only rot, and from constant strong breaths of fittings, improper fixation, fesomes and infrections, they receive severe mechanical damage incompatible with life. Wines in this not tubes, but grief masters who do not know how to properly handle a soft or fragile metal. Anyway, it comes the time of replacement of the tubes, and if the desired configuration is not found, which is almost impossible, then you have to do the tube yourself. Cut the desired piece, wear fittings and ruin. And it is necessary to be able to. Rolling brake pipes With your own hands - the task is not difficult, fast, and inexpensive.

Set for brake tubes

Naked hands will not prepare a copper tube to use. To do this, you need to have at least minimal fixtures. Metal, though soft, but the end of the tube must accurately match the seating cone, otherwise we will not achieve the system tightness. Ideally, for the roller of the tubes, the machine must be used to buy, but if we have the opportunity, you can use the homemade set, which by doing once, we will use for many years. And it will come in handy more than once, believe me. Here is his drawing.

It does not mind anything difficult. This is a bed, made of two corners with a thickness of 5mm and a 32 mm shelf. The length of each corner is 100 mm. The drawing shows that the set is adapted for tubes with a diameter of 9 and 12 mm. The bed itself is performed in ten minutes in the presence of a sharpening machine, drilling machine and a grinder. Both corners are bonded by two M8 bolts, holes and chamdes in them are drilled in the assembled form. The mandrels will have to be ordered or to order from tokar, which is not completely problematic, or to pull themselves. But with this set, any tube turns into an ideally prepared part. The rolling process occurs just as well as using the machine, which we will tell on.

Machine for brake rolling machine

the easiest machine for rolling tubes will cost you 600-700 rubles. But it will be not the highest quality product. We would recommend not to descend below 1800, otherwise there is a chance to spend money in vain. Several sets and machines we have shown in the photo. One of them is more expensive, the second cheaper, but they have one essence.

It consists of a machine from a plank that holds the cutting. Actually, our homemade set also has the same structure, only in branded kits are compulsory:

More expensive models have even greater equipment, but we will consider only the most minimal configuration.

The collapse can be three species, but the first two we are interested in little, because they are used mainly in refrigerators and air conditioners. The collapse occurs as follows:

Thus, we obtain a neat collapsed brake tube, which can be safely replaced by the old one, failed. We cannot say that the machine for rolling tubes should be in every garage, but as a rule, the most valuable things are those that are not always at hand. Watch out for the state brake systemAnd good luck on the roads!

Repair of many car mechanisms can be carried out with their own hands, the collapse of the brake tubes is also able to even inexperienced owner, you just need to correctly determine the need for such an operation. We will tell about it in the article.

What role is the brake pipes play?

In order to understand how important these elements cannot be considered separately, and you should familiarize yourself with the work of the entire braking system as a whole. In order to sharply reset the speed, we click on the appropriate pedal, at this time under the action of the piston pressure, which is in the main cylinder, the special fluid begins to move to the wheels. Its movement is carried out on the highway, which, in fact, consists of brake tubes and hoses.

The transfer of fluid in the system is carried out in the main and duplicate contour. In the case when one of them fails, the second will necessarily work as a safety. When there are no violations in their work, they both operate as the main. If any element of the braking system breaks or will not work well enough, it will violate the work of the entire mechanism, and, it means that the car will be unsuitable for operation.

In which case will the brake tube flavor take?

An explicit feature that it is time to prepare a set for braking tubes, serves the next behavior of the car. With an emergency stop, a characteristic creaking and ripple occurs during the press on the pedal. Also will increase significantly braking distances. In addition, the course of the pedal responsible for an urgent stop will be more free. It is possible that fluid leak will appear from the system, will begin to overheat much, and the pads are unevenly inhabited. Also very often, with such malfunctions, the car leads during the move towards, but this can be considered an indirect sign.

Brake tubes most often fail due to the destruction of the hexagon head structure. Also, there is also often clogging of threaded connections or their encryption when the liquid gets during the operation of the car. Corrosion, microcracks, pollution and other defects lead to the leakage of "TORROSUhi" and incorrect system operation. In order to avoid an unforeseen breakdown, follow the condition of the car, this mechanism should be diagnosed at least once every two years.. Drivers who mercilessly exploit their " iron horse"It is recommended to check the state of this system after every fifty thousand mileage.

The machine for the collapse of the brake tubes - how to apply it?

Most often, the idea that you will have to climb so deeply, causes panic. However, everything is not so scary, as it may seem at first glance, the most important thing is to purchase a tool for the brake tubes, and then can be repaired even independently. If any difficulties arise, or simply do not want to mess around, you can always seek the help of professionals who decide this problem In a matter of hours. But for especially Yarh enthusiasts, we will tell you how to make the ruler on their own.

Primarily, we will need: Truborez, mites, drill, fitting and a special machine for brake tubing rolling. In addition, you need a little gasoline. Then, having prepared everything you need, you can proceed directly to work. By reloading the brake tube from the caliper or the cylinder, with the help of a pipe, we remove its damaged area. Then its cropped edge is dengulated with gasoline. Next, take pincers, clamp the remaining plot so that the protruding edge is about five centimeters, and remove the chamfer drill from this edge inside the pipe. Removing the whole chips, put a fitting on it. Now it will also be necessary for the device for the collapse of the brake pipes, into which its edge is inserted and repair is carried out.

As a result, we must get a neat fungus (expansion) at the end, which will ensure the tightness of the combination of the braking system elements. The size depends on the specifics of your car, but in the repair kit, there are milets into several diameters, so that the preparation of the tool for work and the process itself will not take a long time. Further, all items are installed in place, poured, driven out, and the car is tested for the presence of signs that we described in the paragraph about the diagnosis.

People who drive a lot are quite quickly starting to be interested in the question of how to unravel the brake tube with their own hands. First of all, it is caused by a completely understandable desire for manufacturers of manufacturers to save: in the former times, copper is used to make these parts, which is much more resistant to aggressive conditions of existence and temperature differences. Now they are set steel, which corrosive where as faster.

The second culprit of the unscheduled wear of the brake pipes should be considered utilities. Chemical reagents and salt, generously scattered for the struggle, for example, with a holler, are at times accelerating metal rust and reduce the life expectancy of many details released by the factory. And the third factor forcing the brakes prematurely - sadly glorified russian expensive.

Rytvins and bumps create an unfortunate physical activity, due to which the tubes are deformed, and even burst; In addition, they act as storage of chemical reagents even when the snow has already saved (in spring). All together leads to the fact that the items mentioned are out of 70-100 thousand km, as the manufacturer calculated, and already in 30-50, and even that - in better cases.

How to unraut the brake tube with your own hands: the process is pretty simple, but will require a purchase, independent manufacture, leasing or leaving the neighbor on the garage of a special device for these works. But if you decide to buy a rolling machine, do not seduce the most cheap options on the market. Yes, you can take the adaptation of rubles for 700-800, but it will definitely be very disposable. Experienced way It has been established that a more or less high-quality machine cannot cost 1800-2000 rubles or more expensive.

When is it time to change the tubes?

Symptoms that you need to look for a set for ruin, are:

• During emergency braking, when you click on the pedal, a very characteristic creak is heard;
• Under the same outgoing conditions, rhythmic vibration is felt;
• The brake path of your car is noticeably extended;
• The course of the brake pedal becomes more free, it seems to dangle;
• It is possible to leap the brake fluid (this is especially seen with a sufficiently long parking lot of the car overnight);
• Often there is a significant overheating of brake drums and premature uneven wear of the pads;
• In indirect symptoms - Lavigating the car of the WBOV during the straight movement.

Rolling and its details

Often the main body in the brake tube remains as a whole, but the structure of its 6-face head is destroyed. There may be other options: coking of threaded compounds as a result of liquid falling on them, clogging them, etc. In such situations, if the length allows, you can simply trim the defective part. But it is better to replace the phone completely if there are similar repair. In addition to the collapse machine, mites, pipe cutting, fitting and drill will be needed. From materials - a few acetone.

The brake system of the car is the basis of security and needs professional maintenance. After all, it is from her that the safety of movement by car depends. Today we will tell you about the most terrible breakdowns of the brake system, we describe in detail what kind of braking tubes, for which it is needed and with the help of which tools it is produced.

Brake system malfunctions

Almost all drivers know that the car braking system consists of a control drive, distribution systems and executive (working bodies). All parts of the brake system are connected using brake tubes (highways). On these tubes moves brake fluidunder pressure. In the process of pressing the brake pedal, the pressure on the DW increases and it affects the working body of the system that performs the locking of the wheel and the full stop vehicle.

During the operation of the brake system, the following faults may occur:

• Violation of tightness brake pipes and pistons in which the fluid is under pressure.
• Mechanical breakdown of working bodies. It is possible to include all sorts of brake cylinders and so on.
• Violation of the free stroke of the pedal. Such a malfunction is discomfort to the driver during the operation of the car.

In this article, it will be discussed precisely about the first fault - a disruption of the tightness of the combustion tubes with working mechanisms.

The brake fluid of the car in its composition contains an acid that adversely affects the thin-leaf metal products. In addition, constant impact ambient It may cause corrosion on metal parts. In this regard, the locations of the brake tubes with the working parts of the system may be subject to corrosion and start producing from the braking system special fluid. Another side of the problem is the appearance of air in the system. This phenomenon reduces the pressure inside the brakes and contributes to deterioration. brake properties car.

In order to save money on the purchase of new brake pipes, drivers go to the restoration of the old tube, which passes very successfully. This process was called the collapse.

Rolling brake tubes using a set and device

The collapse is called any deformation or a change in the shape of the tube, which is further fastened to a special product performing a tube connection with a system working body.

This concept refers to the brake system of the car. To make the roller, you need to have a special set for the collapse. It includes a set of devices, such as, cutting device, a deforming device and a set of means for cutting threads on the brake tube.

To carry out the collapse, it is necessary to install a car or overpass and immobilize. From the tank and the main brake cylinder the brake fluid merges. After all the events, it is recommended to replace the new one that in the future it does not climb again under the car. Damaged brake tube unifakes from your landingAnd then remove it from the tube itself.

Cut the damaged plot of the highway, about 5 centimeters. To cut the pipe, you need to install it in a special device and go through the blade across the circumference. After that, the cut end of the pipe is processed to get rid of the irregularities capable of disrupting the shape of the pipe, which means its tightness of the compound.

After that, fix the end of the pipe in a special device and insert the roller fungus into it. A thread shaft is put on top of the fungus, which is attached on another fixing device. Rotate the lever occurs a change in the shape of a cut part of the pipe. Then, depending on the presence or absence of threads, it cuts it on the pipe. In most cases, all brake tubes are manufactured without it.

Install the new end of the tube into the mounting device and tighten the mount nut. Before installing a new tube, it is necessary to clean the sealed part from fat. To do this, it is enough to treat it with acetone or gasoline. After all these events, the fitting is installed in its place, the brake fluid is poured into the system, it is pumping out and after that the car can be operated again.

On this, the brake tubing is complete. As you can see, it is not a complicated procedure and it will be able to cope with almost any car enthusiast, which will have a set of roller set and other garage inventory.

What are the devices for the brake tubing flapping?

In the Arsenal of the car owner who is used to independently repairing his car, in addition to the standard set of tools, including various screwdrivers, wrenches, montits, jack, etc. There must be some special devices that allow you to make one or another effectively. repair work. In this article, I would like to discuss the problem of the rolling of pipes, or rather, to pay attention to the adaptation, with which the specified process is carried out, especially since many motorists consider it a very useful tool.

1. What is the roller tube?

The rolling of the tubes is technological process (operation), the essence of which consists in deforming a certain part of the part in order to increase its diameter (if the diameter decreases, the process is called "rolling"). The specified procedure is carried out in order to obtain a hermetic and durable connection of two pipes, or a tube grid - a collector. In the automotive world, the concept of "collapse" is usually associated with brake tubes, which have to be repaired due to strong wear or leaks.

The entire rolling process is divided into three main stages: the first provides a selection of the gap between the pipe and the tube grille; The second operation is carried out to jointly deform the pipe and the tube lattice; And the third (final) - responsible for removing the load from the inner surface of the pipe.

In the course of the joint deformation stage, the metal pipe is preferably translated into the plastic deformation zone, and the metal tube grid is in the zone of elastic deformations. To ensure such a result, the rule should be observed that it says that the hardness of the lattice material must exceed the hardness of the material from which the pipe is made, due to which, after completing the rolling process, the pipe grille can "clamp" the pipe.

As a result, a press compound is obtained, the tightness and strength of which is ensured by contact pressure, which is formed between the outer surface of the pipe and the surface of the lattice hole (or the second pipe). In some cases, when connecting pipes with pipe lattices, welding use with the collapse, calling such compounds with combined.

In everyday life, the roller is used when it is necessary to fix pipes in boilers, oil coolers, capacitors, steam generators and some other types of heat exchange devices. For the full implementation of the fraud procedure, in addition to the machine itself, with which the operation is performed, you also need to have an electric, pneumatic or hydraulic drive With the ability to control torque. The presence of such a drive will ensure proper quality of the compounds.

2. Principle of action of fixture for rolling tubes

To date, the industry produces a large number of a wide variety of pipes and small tubes used for the operation of various devices and mechanisms. The parts based on the hollow round profile of a constant section are made from cast iron, iron, stainless steel and non-ferrous metals, plastics, metalplastic, rubber and other materials.

In addition, different products are used in different household and industrial conditions. For example, for heating or water supply, for sewage or passage of exhaust gases, for wells or aisle technical fluids. The diameter of the produced pipes may vary from several millimeters to several meters, and for their processing, a large number of different equipment and tools are used. Starting from the collars and ending with bending devices and machines for processing the edges of the parts.

Device (tool) for rolling tubes (no matter, copper they, brake or any other), makes it possible to quickly create a desired profile having a bell shape. As a rule, at the beginning of the rolling process, the tube is cut off with pipe cutters, after which the nut-fixer dresses on it and with the help of a flawer, by rotating the screw, the cone creates a similar profile on the tube.

In other words, the expansion of the cross section by increasing the diameter of the tube makes it possible to create a small fallen at its end. It is he who is a priority, which ensures the implementation of infinity connections of different elements. Having obtained the desired extension, you can insert a smaller diameter tube into the socket and secure it to secure it at the connection site.

Probably, it is worth mentioning about the principle of the operation of the tool for the rolling, because it is often necessary to reduce the diameter of the pipe by narrowing the cross section, so that it can easily enter the fool. Professional device that allows you to qualitatively perform rolling pipes, are special ticks. And in order for processing to require smaller physical effort, it is necessary to choose models with a long handle.

Basically, the specified toolkit is intended for working with copper products. Although copper and cheap material, but in some cases have significant advantages over the rest.

3. Choice of fixture for rolling tubes

Due to the huge variety of all sorts of instruments and materials, choose a suitable device for rolling tubes is very difficult. First of all, when selecting, you should have sufficient information about the parameters and characteristics of the systems for which they will be used.. And the tool itself can be used both to create accurate frames on brass, copper, steel and aluminum pipes, and for their expansion or exhaust.

The collars of copper tubes are manufactured not only by well-known companies specializing in the tools of various kinds, but also little-known manufacturers who are on the market not so long ago. You can pick up simple models consisting of a pair of galvanized plates and a bolt equipped at the end of a cone, and you can also purchase a whole professional set, which includes several dozen individual elements made of chromovanadium alloy.

Such kits, in addition to convenient packaging, represented as a case with a prisoner under each individual element of the device itself, can be supplemented by the brake tubes, and the chamfer processing, a pair of clamping slats with various holes (often, have a knocked outage value) and fragrant nozzles . Depending on the selected model, pipe flawers can be created as a standard cone (at an angle of 450) and some other types of its types, for example, a double seal cone.

Before buying a collaborating tool, you need to have the following information:

The diameter value of the pipe (tube);

Data on the depth of the collapse;

The presence of welding seams;

The characteristics of the material from which the item is made.

The standard rolling tool provides the manufacture of conventional simple frames by 45 °, in the tubes with a wall thickness of 1 millimeter. Low weight and small dimensions make it possible to use this device in the collapse of the joints of the vehicle brake system and cooling systems.

The implementation of the procedure using a tool with a ratchet mechanism requires the master of minimal physical efforts, and smooth and smooth exit are obtained. The ruined cone made of hardened steel is installed in needle bearings eccentric and rotates until a uniform plastic metal deformation. This provides a fully homogeneous state of the filling walls, without any furniture.

Rolling and rolling pipes using a compact collapse (so called the appropriate device), makes it possible to get a special thread, without damaging the material, and the clamping lips, thanks to the multiple capture, allow you to quickly and secure the instrument quickly and securely, without allowing the product slipping. If you additionally apply a metric and inch markup on the matrix, it will greatly facilitate work with pipes of different manufacturers. The special form of a single tool nozzle allows you to apply a ruin and in working with long pipelines, and with pipes, the thickness of the walls of which is less than one millimeter.
