How to adjust the punching pressure of hot die forging press?
hot die forging forming pressIt is the key equipment of modern forging forming, and has a wide range of application processes, including multi-directional extrusion, upsetting, punching, closed-die forging, etc. It is mainly applicable to the forging production of all kinds of special-gauge forgings, shafts, discs and special-shaped parts, such as bearing inner rings, flanges, half shafts, joints, crossheads, hubs, train wheels, etc. Different forgings use different machine pressures, so how to adjust the stamping pressure of the hot die forging press?
Hot die forging press pressure adjustment method: You can look at the pressure gauge to adjust the pressure of the pump, and then adjust the pressure of the hydraulic cylinder. The pressure can be adjusted by simply combining the two. The pressure of the hot die forging press system cannot be higher than that of the pump. Unless it is increased, whether to test the press depends mainly on the load and is automatically generated rather than debugged. The given pressure should be the maximum pressure value for the normal operation of the hydraulic press. Lower the pressure of the overflow valve, close the outlet of the pump in the middle of the throttle valve and the reversing valve, debug the overflow valve, and the pressure at the outlet of the pump rises until it reaches the required value.
In fact, the maximum working pressure of the hot die forging press is the nominal pressure, which is a fixed number. The minimum working pressure of the oil cylinder is the jacking force, and the minimum pressure of the oil cylinder returning or returning is the return force. In short, the tonnage of the hydraulic press is converted into Kg, and then multiplied by 9.8N/Kg is the nominal force of the hydraulic press. The maximum pressure of the working liquid is obtained by dividing the total working area of the total working plunger of the working plunger of the hydraulic press, now do you understand?
