Working principle of Hydraulic Press Machine

  How the Deep Drawing Hydraulic Press works. The areas of the large and small plungers are S2 and S1 respectively, and the forces acting on the plungers are F2 and F1 respectively. According to Pascal's principle, the pressure of a sealed liquid is equal everywhere, that is, F2/S2=F1/S1=p;F2=F1(S2/S1). Represents the gain effect of hydraulic pressure. Like mechanical gain, the force increases, but the work does not gain. Therefore, the movement distance of the large plunger is S1/S2 times the movement distance of the small plunger.

 The Hydraulic Hot Pressing Press is that the oil pump delivers hydraulic oil to the integrated cartridge valve block, and distributes the hydraulic oil to the upper or lower chamber of the oil cylinder through each one-way valve and relief valve. Under the action of high-pressure oil, the oil cylinder is moved.automatic hydraulic press It is a device that uses liquid to transmit pressure. Hydraulic Stamping Press is a device that uses liquid to transmit pressure. The hydraulic transmission system of the four-column hydraulic press consists of a power mechanism, a control mechanism, an actuator, an auxiliary mechanism and a working medium.The power mechanism usually uses an oil pump as the power mechanism, usually a positive displacement oil pump. In order to meet the requirements of the movement speed of the actuator, one oil pump or multiple oil pumps are selected. Low pressure (oil pressure less than 2.5MP) uses a gear pump; medium pressure (oil pressure less than 6.3MP) uses a vane pump; high pressure (oil pressure less than 32.0MP) uses a plunger pump. Pressure processing and forming of various plastic materials, such as extrusion, bending, deep drawing of stainless steel plates and cold press forming of metal parts. It can also be used for the suppression of powder products, grinding wheels, bakelite, and resin thermosetting products.
