Abstract: To mine car frame girder for forming process analysis, with AutoForm software rebound calculation, the results of the analysis according to the rebound in ThinkDesign to girder local for the springback compensation, in the mold structure design also takes into account to springback control. Through the forming process of the optimization and reasonable die structure design, got to meet quality requirements of the girder products, and meet the needs of the mass production.
