Design of punching progressive die for connecting plate
 
Abstract
 
Motor rotor core which belongs to the typical punching parts, based on the analysis of the process, according to the production requirements, determine the structure of progressive die. This design is mainly the design of the blanking punch and die and punch and die, need to calculate the punch and die clearance, part dimensions and tolerances. In addition, also need to determine the overall size of mold parts and structural parts and mould, and then according to the design drawing mold assembly diagram above.
