Background
In recent years, with the development of science and technology, the appearance of novel materials and various requirements such as complicated product shapes and the like are met, so that the traditional press can not meet various processing requirements any more, and the press is produced at the same time. The blank holder force acts on the sheet through the blank holder, so that the sheet generates friction force between the blank holder and the die to control the flow of the sheet and avoid wrinkling. At the same time, this also causes an increase in the tensile stress in the material. The reasonable blank holder force is very important, and the blank holder force is too small to control the flow of the plate material, so that wrinkling is caused; the blank holder force is too large, and although wrinkling can be effectively avoided, tensile stress is increased, and tensile crack can be caused. In press systems, the press air cushion then acts to control blank holding pressure.
Press cushions are an accessory system of presses that function to hold the sheet prior to drawing and hold it down during the forming process to prevent wrinkling due to too rapid material flow during the material forming process. The traditional press air cushion generally adopts a hydraulic device, and the air cushion can guide the energy of a flywheel into a hydraulic cylinder in the return stroke. Energy waste in the whole stamping stroke is serious. In addition, the conventional press machine air cushion such as a pure air cushion, a numerical control hydraulic air cushion and the like has limitations, such as low working pressure, high energy consumption and the like. This forces people to find a more suitable air cushion device based on the original air cushion.
