EDM Surface Strengthening Research on Rubber Mold

Abstract:

Spark deposition technology is a kind of important means on rubber mold surface strengthening and repair .The temperature field for 2A12 Aluminum Alloy during EDM surface strengthening is simulated and analyzed through establishing proper finite element model based on finite element software. The results show that: During the strengthening, temperature field is mainly concentrated on the surface of work-piece and has little influence on the internal of work-piece. The temperature field of the surface of work-piece has the dynamic effects, which moves with the movement of the strengthening point and becomes stable as time passes. During the strengthening, the temperature for nodes on the surface decreases slowly after rising rapidly, and the strengthening point has the highest temperature. The barrier of the insulated boundary has a great influence on the distribution of temperature.
