Often there are situations when it is impossible to carry out actions for servicing vehicles on your own or when you encounter difficulties during repair and installation work due to lack of physical effort. The best manufacturers have launched the production of hydraulic presses, which have become the most reliable assistants. At the same time, it is called a press conditionally, since it is often used in heavy industry (for stamping parts).

What it is? The hydraulic press belongs to the category of special equipment designed to create increased pressure in the process of processing various materials and metals. Structural elements are several cylindrical vessels equipped with pistons of different diameters. The operation is based on the law of hydraulics, which involves the transfer of the indicated pressure indicator of the liquids in the containers in any direction. To improve efficiency, a special oil is poured into the press, due to which the pressure indicator increases to the required indicator.
The most common device of this type is considered to be jacks, which allow an ordinary person to lift a significant load without making significant efforts. A similar system of functioning for drives, shock absorbers, brakes and pumps. The unit gained popularity largely due to the ability to simplify the work of a person by transferring a designated energy flow to flexible and thin hoses.
Several types of devices are available:
Equipment classification is shown in the comparative table:
Options | Name |
---|---|
By arrangement of cylinders | Vertical and horizontal. |
By type of work performed | Forging, stamping, bending and beading and flanging. |
By the type of bed used | Rack and column. |
There are differences in the principle of execution, in connection with which the following types are distinguished:
If you look at the rating of quality products, then all modern options are equipped with CNC. You can set the required operating mode and select the pressure. Permanent human monitoring of the machine is not provided. This function is transferred to the computer.

Today, you cannot find a production facility that does not use hydraulic presses. This device is designed to perform numerous functions, such as:
It should be borne in mind that the design of the device is quite simple, and it is not particularly difficult to work on it. In addition, it completely mechanizes manual labor. Due to these characteristics, the instrument has been very popular in various spheres of life for a long time. However, it is not recommended to work on it without prior preparation and listening to instructions, as well as without a medical examination and special equipment, according to safety regulations.
The main task of the device is to compress the material strongly, for which there is not enough human strength. It is mainly used where there is a need to deform parts or to pack materials into dense briquettes with the subsequent manufacture of various products.
The design has been used by our ancestors since time immemorial. It was endowed with special functions that made it possible to squeeze out grape or apple juice quickly and efficiently. She was an indispensable unit in the manufacture of oil.
There are many types of equipment that differ in size, weight, configuration, functionality, cost. Compact versions of the manual type are available for crimping products with aluminum and copper lugs. And there are also massive ones, weighing up to half a ton, with significant dimensions and high power. These are installed in furniture factories and production workshops of large industrial enterprises, where they are used for the manufacture of plywood, plastic products, MDF sheets, and so on.
