The Design of Multifunctional Corkscrew Punch Technology and Mould
Abstract: This design mainly expounds a kind of multi-functional corkscrew stamping mould main design process, the main principle is to use convex, concave die cutting processing for the target parts. The main purpose is to design multi-function corkscrew punching blanking forming composite die. This paper mainly the blanking pieces of technology and layout mode. In the process of cutting force hedge process and pressure center has been calculated and analyzed, and hedge die size of the blade of calculations. The structure of the die cutting a hedge design and calculation, and at the same time for each of the mould manufacturing main parts structure size is calculated, according to the material to select the suitable parts to ensure the mould manufacturing. This figure, and drawing equipment mould of important the standard parts chart drawing.
