In high-efficiency mechanical press, they can reduce the sliding impact on workpieces or strengthen the drawing force in the whole drawing stroke in the optimal way. This means that the material flow can be controlled during the forming process, so that complex geometries can be manufactured without tearing or wrinkling the workpiece. The pre-acceleration of the hydraulic cushion equipment further improves the process, realizes longer mold service life, causes less surface damage to the mold and has lower noise level of the machine. The hydraulic cushion equipment is composed of a top crown, a hydraulic cylinder, a hydraulic valve station, a pipeline system, a pump set and a control system.
