Experimental and continuous stamping simulation study on surface wear of hardened steel mold
Abstract Many researches on mold wear are based on numerical simulation of single stamping, which is difficult to reflect the cumulative wear caused in the real continuous stamping process. By designing the stamping trajectory, a numerical simulation method based on continuous stamping is proposed. The modeling of the mold is analyzed and the formula of the wear amount is deduced. And a series of tests are designed to analyze the surface morphology which provided the theoretical and factual basis for numerical simulation and verifies the correctness of the numerical simulation method. Then the variation of heat, wear and stress field distribution during continuous stamping process are investigated by numerical simulation. The relationship between the stress and wear increment of the mold is studied. Finally, the variation rule of the wear amount after continuous stamping is summarized and the criterion of entering the steady wear state is given. The maximum wear depth is fitted linearly and the service life is predicted. This provides a theoretical basis for studying the wear rules of the dies in the continuous stamping process.
