The Use And Characteristics Of Hydraulic Press

2022-10-31

Hydraulic press (a type of hydraulic press) is a kind of hydraulic press that uses special hydraulic oil as the working medium, uses the hydraulic pump as the power source, and relies on the force of the pump to make the hydraulic oil enter the cylinder/piston through the hydraulic pipeline, and then there are several parts in the cylinder/piston. The seals that are matched with each other have different seals at different positions, but they all play a role in sealing, so that the hydraulic oil cannot leak.

Finally, the hydraulic oil is circulated in the oil tank through the one-way valve to make the cylinder/piston cycle work to complete a certain mechanical action as a kind of productivity machine.

Features

The hydraulic press directly driven by the hydraulic press pump has the following characteristics

1. The stroke speed of the movable beam of the hydraulic press depends on the liquid supply of the pump, and has nothing to do with the deformation resistance of the forging in the process. If the liquid supply of the pump is constant, the working speed of the hydraulic press is constant.

2. The hydraulic supply pressure and power consumption of the pump are related to the deformation resistance of the workpiece to be processed. The working deformation resistance is large, and the hydraulic supply pressure and power consumption of the pump are also large, and vice versa.

3. The characteristics of the constant travel speed of the movable beam and the change of the hydraulic pressure of the pump can be used as the signal for operating the distributor to realize the automatic control of the hydraulic press.

4. The basic investment is low, the floor area is small, and the daily maintenance and maintenance are simple. The hydraulic pumps in the pump direct drive system are selected according to the maximum working speed and working pressure of the hydraulic press, and the hydraulic pump cannot be fully utilized when the hydraulic press has a small filling stroke, return stroke, auxiliary process and required working pressure, especially It is a large-tonnage hydraulic press, and its utilization coefficient is very low. Therefore, the hydraulic press tends to transmit the working speed and working pressure in stages
