What is a hydraulic press and how does it work?

Many auto repair jobs require strong pressure or even pressing on parts. hydraulic press. The device, with minimal effort, exerts a lot of pressure on objects, which is explained by the laws of physics. The catalog of the Grand Instrument website contains hydraulic presses from leading manufacturers.

Peculiarities of using a hydraulic press

A hydraulic press consists of two connected vessels, a liquid, a rod and two pistons of different sizes. During the use of the unit, the small piston exerts pressure on the oil, the oil on the large cylinder, which drives the rod. The rod with the nozzle, in turn, acts on the part.

The clamping device can be used for:

• forging metal products;
• correcting the geometry of parts made of metal;
• pressing or joining parts;
• creating bends.

The workshop press is small and easy to transport. According to the principle of operation, the device can be mechanical or electrical. In the first case, for pressing, you need to exert pressure on the lever, in the second, press the corresponding button. Press pressure is an important indicator that requires attention. Productivity in the range of 15–30 tons is a value suitable for working with car parts, including silent blocks. Units with a pressure of 50 to 100 tons cope with the spare parts of trucks and SUVs.

Rules for choosing a hydraulic press

To work with a hydraulic press efficiently, during his purchases need to consider a few details. The first is the dimensions and installation method. For a small box, choose a portable desktop model. In a large room, you can install a stationary full-size press.

The ease of workflow directly depends on the functionality of the press. For safety, the design of the device must provide for the possibility of blocking operation during a breakdown. The rotation of the cylinders and the function of controlling the applied forces make the process partially automated.

When choosing a press, pay attention to what size of the part you will use in your work and, based on this, select the power of the unit. In the online store Grandinstrument you can buy a pressing device with a force of 10 to 75 tons.
