Deep Drawing Press with Die Cushion
2022-05-10 13:51:17
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.
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 hydraulic cylinder, the lower hydraulic cylinder piston is forced to descend when the upper hydraulic cylinder slide is pressed down. The oil in the lower chamber of the upper hydraulic cylinder enters the upper chamber of the lower hydraulic cylinder, and the oil in the lower chamber of the lower hydraulic cylinder flows back to the oil tank through the relief valve 16 of the lower hydraulic cylinder, which can be adjusted by adjusting the opening pressure value of the relief valve 16 The required jacking force of the lower hydraulic cylinder.
According to the size characteristics of the workpiece, the deep drawing press with die cushion has two types of fuselage structure: four-column type and frame type. The speed control of the second stage of the movable beam of the hydraulic press machine is no-load high-speed, slow-speed die drawing. The upper and lower limit protection of the movable beam, the stroke can be adjusted. It has an independent electrical control system, reliable, audio-visual, and convenient for maintenance, centralized control of buttons, adjustment, semi-automatic, automatic. Operation panel, continuous stroke and pressure, with pressure control and time delay function. Stroke and pressure can be adjusted according to actual use. Use die cushion for deep drawing press.
