The working speed of the hydraulic press machine is very slow? Can't it be faster like the return speed? Is it deliberately limited during the design, or can it not be achieved?

The hydroforming process of hydraulic press machine is widely used in the automotive, aviation, aerospace and pipeline industries. It is mainly suitable for: circular, rectangular or special-shaped cross-section hollow structural parts that change along the component axis, such as special-shaped pipe fittings for automobile exhaust systems, non-circular Cross-section hollow frames, such as engine brackets, instrument panel brackets, body frames (accounting for about 11% to 15% of the mass of the car), hollow shafts and complex pipe fittings, etc.

                                        

The operating speed of the hydraulic press machine is determined by the working flow. The power of the hydraulic pump is proportional to the product of working pressure and flow, that is, pump power = P*Q. When the hydraulic press returns, the load of the hydraulic press is small and the working pressure is low, so The flow rate can be increased while ensuring that the output power of the hydraulic pump is not exceeded, that is, the operating speed of the hydraulic press is increased. When the hydraulic machine is in operation, the load of the hydraulic machine is large and the working pressure is high. Therefore, to ensure that the hydraulic pump is not overloaded, the flow rate needs to be reduced, which reduces the working speed of the hydraulic machine. In short, it is necessary to ensure that the hydraulic pump (pump motor) is not overloaded. The flow rate is low when the pressure is high, and the flow rate is high when the pressure is low. The operating speed of the hydraulic machine is only related to the flow rate, that is, the flow rate is large, the speed is fast, and the flow rate is high. Small and slow.
