If the pump supply volume is constant, then the working speed of the oil press is fixed. Therefore, the hydraulic press tends to drive the working speed and the work pressure.
  Widely used in parts of the automotive industry and the processing industry of many kinds of products, stereotypes, trimming correction and footwear, handbags, rubber, mould, shaft, shaft sleeve pressing, stamping molding, sheet metal bending, stamping, sleeve drawing process, washing machine, electric motors, motor cars, air conditioner motor, micro motor, servo motor, wheel damper, and motorcycle manufacturing, machinery and other industries.
  The pump pressure and the power consumed are related to the deformation resistance of the workpiece to be machined, the deformation resistance of the work is large, the pump pressure and the consumed power are also large, whereas the opposite is small.
  Basic investment, small footprint, simple daily maintenance and maintenance.
  The utility model can be used as a signal of an operation distributor to realize the automatic control of an oil pressure machine by utilizing the characteristics of the constant flow speed of the flow beam beam and the change of the pressure of the pump supply fluid. Hydraulic pump direct drive system were selected according to the press the maximum working speed and working pressure, and oil press in liquid filling and return stroke, the auxiliary process and the required working pressure is small, the hydraulic pump are not fully utilized, especially large tonnage hydraulic machine, the utilization coefficient is very low.
  The stroke speed of the flow beam of the hydraulic press depends on the amount of liquid supplied by the pump, and has nothing to do with the deformation resistance of the forging in the process.
