Characteristics and Use of Hydraulic Press Machine

I. Learn about the hydraulic press machine

Hydraulic press machine is one of compression machine types 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 groups in the cylinder/piston. The seals that cooperate 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. The hydraulic press machine consists of two parts: the main engine and the control mechanism. The main part of the hydraulic press machine includes the fuselage, the main cylinder, the ejector cylinder and the liquid filling device. The power mechanism consists of a fuel tank, a high-pressure pump, a low-pressure control system, an electric motor, and various pressure valves and directional valves.

II. Characteristics of hydraulic press machine

1. The stroke speed of the movable beam of the horizontal hydraulic press machine 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 volume of the pump is constant, the operating speed of the hydraulic press machine is constant.

2. The hydraulic pressure of the pump and the power consumed are related to the deformation resistance of the workpiece to be processed. The deformation resistance of the operation is large, and the hydraulic pressure of the pump and the power consumed 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 to operate the distributor to complete the automatic control of the hydraulic press machine.

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 operating speed and operating pressure of the hydraulic press machine, and the hydraulic pump cannot be fully utilized when the hydraulic press machine has a small filling stroke, return stroke, auxiliary process and required operating pressure. It is a large-tonnage hydraulic press machine, and its utilization coefficient is very low. Therefore, the ezhong hydraulic press machine tends to transmit the working speed and working pressure in stages.

III. Use of hydraulic press machine

Hydraulic press machines are widely used in the processing of spare parts in the automobile industry and the shaping, edge punching, calibration of various products in various industries, and the pressing, embossing, and plate parts of shoemaking, handbags, rubber, molds, shafts, and bushings. Bending, embossing, sleeve stretching and other processes, washing machines, electric motors, automobile motors, air-conditioning motors, micro motors, servo motors, wheel production, shock absorbers, motorcycles and machinery industries.
