The stamping process and mould design for the beam back suspension track bar of automotive
[Abstract] Stamping process is a kind of very wide application processing technology. Stamping parts in various industries in both occupy a large proportion, in aviation, automobile, tractor, electric appliances, precision instruments, light industry occupies a very important position in the processing. According to preliminary statistics, only the automobile manufacturing industry is almost60%-75% parts using high pressure processing technology. This paper mainly describes the car beam rear suspension thrust rod stamping process and die design of the specific steps. In the paper on the punching, blanking, bending and other steps, at the same time to spare parts plate layout, blanking force calculation, mold edge size calculation of key issues, are given in detail the calculation process. This paper is the application of the CAD, software such as UG, drawing, so that the subject is more intuitive, three-dimensional, more convenient for us to know.
[Key words]: Stamping; mold design; bending; thrust rod
