[0002] Hydraulic forging press is mainly used for the drawing forming, the turn, the bending and the stamping process of metal sheet parts, and can also be used for general pressing process. In addition, it can also be used for the pressing process of shaft parts, the calibration of profile, the buckling, the pressing process and the bending of plate parts, such as stamping, bending, flanging, thin drawing and other operations.

It does not have the function of intercepting and filtering the impurities in the hydraulic oil, and lacks the control of the viscosity of the hydraulic oil. If the viscosity of the hydraulic oil in the hydraulic cylinder is too large, it will increase the viscous resistance loss, reduce the suction performance of the pump, make it difficult to start, even cause cavitation, and reduce the control sensitivity. If the viscosity is too low, it will increase the leakage of the hydraulic oil and reduce the volumetric efficiency.
