Often there are situations when it is not possible to independently carry out actions to service vehicles or have encountered 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 type press belongs to the category of special equipment designed to create increased pressure in the process of processing various materials and metals. The 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 liquids in containers in any direction. To improve efficiency, special oil is poured into the press, due to which the pressure indicator rises 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 significant effort. 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 the indicated energy flow to flexible and thin hoses.
Several types of devices are available:
Equipment classification is given in the comparative table:
Options | Name |
---|---|
According to the location of the cylinders | Vertical and horizontal. |
By type of work performed | Forging, stamping, bending and for beading and flanging. |
By type of machine 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 goods, then all modern options are equipped with CNC. You can set the required operating mode and select the pressure. Permanent control of the machine by a person is not provided. This function passes to the computer.
Let us dwell in more detail on the main types of presses.
