Hydraulic Quick die clamping system (HQDCS) mainly focuses on rapid clamping and unclamping die. It is concerned particularly with the productivity improvement by reducing the timing of die clamp-unclamping. HQDCS is a system, which is a safe, quick and simple way to clamp dies, workpieces. The organizations are facing the problem of reduction in productivity and it is due to maximum loading and unloading time of die. To achieve these objectives there is need to study the various clamping system, hydraulic system and improvement in productivity by HQDCS system. With HQDC system, only button operation is required to lock the die. Die change time would only take a few minutes. A further object of this invention is to provide a hydraulic clamp for quick die clamping of the press machine and makes the use of the already existing hydraulic system. Implementation of HQDCS improves machine efficiency, clamping time and this ultimately improves production rate.
