Finite Element Analysis and Wear Mechanism Research on Feed Punch of Die-casting Machine
The friction between the punch and the fusing cylinder in feeding process of die casting machine was simulated by finite element analysis method.The stress distribution of the punch during feeding process was obtained based on finite element model and material constitutive relations of the punch and fusing cylinder.The results show that the simulation results are consistent with the test results in actual situation,which provides a strong support for researching punch's wear and increasing punch’s life.
