Abstract
Hot stamping technology is widely used to produce car body components with more complex shape, higher strength, and less springback. A pair of optimal hot stamping tool should have a long service life, low manufacturing cost, and good cooling performance simultaneously. Consequently, a new manufacturing method of hot stamping tool with CCC (conformal cooling channels) is introduced in this study. Besides, CuCrZr and Fe-based alloy were welded on the specimens as intermediate layer and surface layer respectively, high-temperature compressive yield strength, the heat conductivity, and thermal expansion coefficient of welding materials were measured. The whole stamping process of the new hot stamping tool is simulated and discussed. The simulation results indicate the maximum stress in each area of the new tool was less than the yield strength of the corresponding welding materials, which demonstrated that the new tool manufactured by surfacing technology could meet the strength requirement and deserve further research.
