Structural Characteristics of Hydraulic Press 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. Under the control of the electrical device, the power mechanism realizes the conversion, adjustment and delivery of energy through pumps, oil cylinders and various hydraulic valves, and completes the cycle of various technological actions.

hydraulic press machine structural characteristics
The hydraulic press machine 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 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 machine, 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 the large-tonnage hydraulic press has a very low utilization factor. Therefore, the hydraulic press machine tends to transmit the working speed and working pressure in stages.
