Description

technical field [0001] The invention belongs to the technical field of moulds, and in particular relates to a structurally improved progressive punching die. Background technique [0002] The progressive die is composed of multiple stations, and each station is connected in sequence to complete different processing, and a series of different stamping processes are completed in one stroke of the punching machine. After one stroke is completed, the punch feeder moves the material forward according to a fixed step distance, so that multiple processes can be completed on a pair of molds, but the existing punching progressive dies are difficult in punching and unloading. There are flaws and needs to be improved. Contents of the invention [0003] The object of the present invention is to solve the above technical problems and provide a structurally improved progressive punching die. [0004] To achieve the above object, the present invention adopts the following technical sol...
