Abstract：

During the production of L-shaped section ring forgings, if the dimensions and structure of the blank are designed unreasonable, then it is prone to engender defects of groove, clip skin and burr in rolling process,which directly affect the service life of mould. According to its volume principle and metal distribution principle in forging process, and based on rigid translation principle , the blocking technology was put forward, then the interface was correctly chosen, the blank was designed optimally, and the shape and dimensions of mask mode were confirmed. With the finite element numerical simulation , the rolling process was simulated and analyzed optimally. The experiments show that the mask mode designed by this technology can effectively avoid that defects, and the simulation results coincide with experimental data well.
