Design of Civil Low-Pressure Vessel’s "4 in 1" Stamping Compound Dies

Traditional stamping process of civil low-pressure vessel deals with blanking, drawing, trimming and flaring process in different processing station separately, work-piece transmission between different processing stations increases the auxiliary time, and the work-piece needs reinstallation, reduce production efficiency and increase production cost. In order to overcome the above disadvantages, the optimized stamping technology process is designed, compress four process (blanking、drawing、trimming and flaring) into a integrity process, and the development of a "4 in 1" stamping compound dies, that makes stamping automation realize easily, improve processing efficiency, easy operation, and reduce the product processing cost and labor costs, and enhance economic performance.
