COMBINED FLOWING STAMP

摘要

This die is used in metalworking and machine engineering for producing polar stars, with a semi-plug, for a generator. It enhances the wear resistance of the elements and the pressing efforts are reduced. The die consists of a top mobile plate /15/, to which is attached a deforming punch /16/. The top plate is connected to a bottom static plate /1/ with columns /13/. The bottom plate holds a compound matrix /8/, located on at least three spiral springs /9/. The opening of the matrix holds a hollow ejector /7/, which encloses a bottom deforming punch /5/ and touches three ejecting pins /11/, located in the bottom plate, and connecting with a compact ejector /12/, located below the bottom plate.
