摘要

According to processing characteristics of getting rectangular holes after forming of the cylindrical part with prefabricate-holes, the optimum blank shape of the cylindrical part is necessary to improve product quality and reduce production cost. Theory analysis and numerical simulations combined with inverse finite element method and forward finite element method by using ETA/DYANFORM were employed to investigate the influence on blank shape by the holes, modify the reverse blank shape and optimize the deep drawing by forward simulation, and finally obtain the forming law of the cylindrical part with prefabricate-holes.
