[0001] The utility model relates to the technical field of progressive dies, and specifically relates to an adjustable pitch progressive die. Background Technique

[0002] A progressive die (also called a continuous die) consists of multiple workstations. Each workstation is sequentially associated to complete different processes. A series of different stamping processes are completed in one stroke of the punching press. After one stroke is completed, the material is moved forward by a fixed pitch by the feeder of the punching press. In this way, multiple processes can be completed on a set of dies, generally including punching, blanking, bending, trimming, drawing, and so on.

[0003] Existing progressive dies usually use roller, chain or gear systems to adjust the pitch between workpieces. However, during processing such as punching and blanking, certain impact force and vibration will be generated, which can easily cause the rotation of the roller, chain or gear system, resulting in displacement, and reducing the stability of the pitch adjustment of the workpiece. Therefore, an adjustable pitch progressive die needs to be proposed. Content of the Utility Model
