The design of multi-position progressive die for side-bending stents
Abstract: The technological property of a side bend bracket was analyzed in this graduation project,and a progressive die was designed to produce qualified products based on this analysis.The mainly process of this progressive die includes punching, cutting tongue and bending;the die design includes layout design,the design and calculation of blade sizes of punch and matrix dies, the calculation of blanking force and the confirmation of the pressure center of a mould,the design and calculation of non-standard die pieces;the choice and check of the press.
Key words: craft;the level enters the mold;punch holes; cutting edge
