|
The shape and structure of automotive lining parts are complex, the surface quality requirements are high, and the outline sizes are larger. For the problems of slip, springback, wrinkling，crack and other defects in the forming process, the stamping process property of a certain automobile lining part was analyzed in detail, and the forming process plan of fourteen positions including punching, drawing, embossing, flanging and bending was designed. In order to avoid repeated on-site die debugging in the later stage, the forming process and quality defects in the early stage of stamping process design were predicted and evaluated by analysis software CAE. In addition, a series of key points of die structure design were introduced, such as lifting shockproof structure and springback compensation structure etc., and the working process of multi-position progressive die was expounded. Furthermore, the feeding mode adopted automatic feeder to realize the fully automatic production of automotive lining parts and ensure the production efficiency of products.
