Recently manufacturing field of Automobile has been requested cost reduction and long life, various studies have been developed by changing the forming method reducing cost with same quality level. The product in this paper is one of automobile auto-transmission parts changed forming method from hot forging to cold thick plate forming.
The objective of this paper is a research work for the improvement of formability of thick plate considering the clearance between punch and die as clod thick plate forming. In order to find an optimized clearance between punch and die with a thick plate that is 6mm thickness based on S53C material, tensile test was carried out for the finite element analysis (FEA). The computational analysis and experiment were tested. They were compared each other with 3 cases; 5%, 10%, 15% clearance between punch and die. Thus, the best shear surface was shown at 5%, 10% clearance from the computational analysis and it was shown the same result from the experiment. However, it showed that the experiment shows damaged portions in both die and punch. In conclusion, the optimum condition for a good shear surface or protecting die is 13% clearance between punch and die. Moreover, it can expect that the percentage of the clearance can improve a die life.
