Abstract：

Online roller punching is a new process for the need of high speed punching in the cold roll forming line. A new type of roller punching set in which the new mould structure of steel punching pairing polyurethane die was developed, and high speed continuous punching of low carbon steel strip with the thickness less than 1 mm could be finished. During the development of the moulds, Deform 3D FEM software was used to simulate the polyurethane punching process in detail, and the optimization design of punch was analyzed. With the analysis of the simulation and test results, the inner oblique edge punch has a very excellent punching process of the hole shape and punching load.
