The bottom of deep drawing press is equipped with a hydraulic pad, which can be selected through the operation panel. This series of hydraulic presses are suitable for various stamping processes such as deep drawing, bending, forming, blanking and flanging. Die Cushion Of Deep Drawing Press Principle Some molds need to be pressed and drawn when the workpiece is working. When the mold is used as a thin plate deep-drawing edge holder on a four-column hydraulic press, the lower slider is required to rise to a certain position to realize the clamping of the upper and lower molds, so that the clamped mold can not only maintain a certain pressure to clamp the workpiece, but also make the mold. Descends as the upper slider is pressed down (edge press). At this time, the lower cylinder reversing valve 14 is in the neutral position. Since the pressing force of the upper hydraulic cylinder is far greater than the upward pushing force of the lower hyd...
