A new type of hydraulic die pad for 500 tons punch press

Abstract

The invention discloses a novel 500-ton punch press oil-pressure die pad. The novel 500-ton punch press oil-pressure die pad comprises a punch press body, an upper die pad, a lower die pad and lower press material cylinders, wherein the punch press body is provided with a cavity, and a mounting block is fixedly connected to the top end of the cavity; the upper die pad is fixedly connected to the bottom end of the mounting block, the upper die pad is provided with counterbores, and protective sleeves are installed in the counterbores; sealing plates are installed at the bottom ends of the protective sleeves, upper press material cylinders are installed in the protective sleeves, an upper die is fixedly connected to the ends, extending out of the sealing plate, of the upper press material cylinders; and the low die pad is fixedly connected to the bottom end of the cavity, and the low die pad is further provided with counterbores. According to the novel 500-ton punch press oil-pressure die pad, the positions of the dies can be conveniently adjusted to adapt to different product processing, a plurality of sets of cylinders are arranged, and the cylinders occupy small space, installation and maintenance are easy, the recoil speed can further be adjusted to facilitate taking materials, the sound made by a punch press is effectively reduced, the hearing health of workers is facilitated, the service life of the punch press is prolonged, and the practicability is higher.

Description

technical field [0001] The invention relates to the technical field of punch press hydraulic die pads, in particular to a novel 500-ton punch press hydraulic die pad. Background technique [0002] Pneumatic die pads and hydraulic die pads are commonly used for punch presses. Pneumatic die pads need to be equipped with pits with the enlargement of pneumatic cylinders, which leads to larger devices, and pneumatic die pads are caused by compressive fluids. Pressure fluctuations and vibration during collisions accompanied by insufficient tilt, so the pneumatic die pad can also be called an old-style die cushioning device, while the existing hydraulic die pad cannot be adjusted in position, maintenance is troublesome, and it is difficult to operate in actual operation. Problems are prone to occur in the process, and insufficient hardness in use may easily lead to cracks in the product forming process, which is not suitable for long-term use. [0003] Therefore, a new type of 500...
