Background

Progressive die (also called progressive die and jump die) refers to a die which is used for finishing multiple working procedures at different positions in sequence in one stroke of a press. The blanking piece is formed step by step in a continuous die, and the continuous forming is a process method with concentrated working procedures, so that various working procedures such as trimming, cutting, grooving, punching, plastic deformation, blanking and the like can be finished on a pair of dies. According to the actual requirement of the stamping part, a plurality of stamping working procedures (called stations in a progressive die) are arranged in a certain sequence for continuous stamping. The punching die not only can complete the punching process, but also can complete the forming process, even the assembly process, and a plurality of complex stamping parts requiring multi-process stamping can be completely formed on one die, so that the advantage is provided for high-speed automatic stamping. Therefore, the continuous die is a blanking die with multiple stations and high efficiency.
