Abstract：

The closed forging process scheme and mold assembly drawing of the 20CrMnTi work clamping piece were designed based on its structure analysis. In order to verify the feasibility of the design process, reduce trial cycle and save production cost, three-dimensional dynamic simulation model of the working clip closed forging deformation was established by the Deform-3D finite element simulation software. Then, a production cycle of forging process was simulated. The simulation results show that the designed closed forging process is feasible and the mold structure is reasonable. Furthermore, the force distribution of the die is more complex than that of the punch, and the force distribution of punch 1 is more complex than that of punch 2. Therefore, the die should be prioritized when the mold is designed. The test results show that the qualified work clamping piece can be obtained by the optimized process, namely that the mold materials is 3Cr2W8V, initial forging temperature is 1200 ℃ and final forging temperature is 900 ℃.
