Why are riveting machines needed and what are they?

In the mechanical engineering field, it is difficult to do without special devices. The most common group includes a riveting machine for car pads. There are several types of such machines. They have the same purpose, but differ in technical characteristics.

Riveting machines are special devices, the purpose of which is to rivet and rivet linings on clutch discs and brake pads. Simply put, with the help of such equipment, you can make timely and high-quality car repairs.

Now such machines are very popular due to the increase in the number of cars. Repairs are cost effective for the vehicle owner compared to purchasing new parts. In addition, some are suitable for additional operations, for example, for boring chainsaw chains.

According to the principle of operation, all riveting machines are divided into several categories. The first three include the most common models of machine tools (they are also called orbital). The fourth and fifth categories are less popular machines, but they are also used in garages.

The groups are as follows.

• Pneumatic - these are the most common and inexpensive machine models. They are often used in car services of various levels. For this type of machine, a connection to a compressed air supply is required. In this case, work is carried out using special pneumatic cylinders. They are the main working part that participates in the riveting process.

• Pneumohydraulic - in this category there are machines that are as close as possible to the first category. Operation also requires a connection to a compressed air source. The only difference is that a special hydraulic cylinder exerts pressure on the rivets. With the help of compressed air, oil is supplied to it, it begins its work, performing the main and additional functions.

• Hydraulic - machines of this type are rarely used on a professional level. More often this option can be found in garages. They are intended for the repair of car parts. A distinctive feature of these machines from the representatives of the two previous categories is manual control. In this case, productivity decreases several times, but the quality remains unchanged.

The fourth and fifth group includes mechanical and electrical machine tools. They are less popular due to some technical features.

A few years ago, only large car workshops could afford such equipment. Now the assortment on the market is much wider. Small riveting machines are often bought both for their own garage and for small car services.

In each of the above categories, there are the most popular devices, which differ from each other in technical characteristics.

If we talk specifically about pneumatic devices for repairing pads, then here the most popular representative is rightfully considered an apparatus called Nordberg NR6... The machine is presented in gray-blue color, has a standard shape. The main purpose of such a device is to install and remove rivets up to 10 mm in diameter. The main advantages are:

• high speed of parts processing;

• ease of use;

• the ability to adjust the riveting force;

• runs on compressed air;

• can handle rivets from various materials - copper, steel and aluminum.

The weight of such a machine is about 92 kg. The cost is relatively high - from 77 to 72 thousand rubles.

In the category of pneumatic-hydraulic devices, the most common model is considered Nordberg NR6H machine... It will be required when installing rivets with a maximum diameter of 10 mm. And also the machine will come in handy if the pads on the clutch discs are being replaced. The advantages of this device are:

• stable centering;

• high performance;

• complete set with an additional bracket designed for the convenience of working with brake pads.

The weight of the device is exactly 100 kg, and the cost varies from 100 to 103 thousand rubles.

These two machines are large and are more suitable for mechanical workshops or large auto repair shops where trucks are being repaired.

For private use, it is recommended to purchase a more compact model - riveting machine JTC-1517... It is made in red, and the weight of such equipment is only 30 kg (that is, three times less than in previous versions). Machine advantages:

• small dimensions;

• good performance;

• the ability to work with rivets of different diameters (4, 6 and 8 mm).

And also it is equipped with additional accessories. Among the disadvantages, it should be noted the relatively high cost. It varies from 88 to 90 thousand rubles. The price is almost the same with large-sized devices. But in this case, the undeniable advantage is the portability of such a device. It is easy to move it from place to place, while options 1 and 2 are problematic to move.
