Study on Factors of 22MnB5 Steel Anisothemal Drawability

Abstract:

A finite element model was established for analyzing 22MnB5 steel anisothemal drawing of square box at high temperatures. Based on the orthogonal experiment, the effect of tool temperatures, including die temperature, binder temperature and punch temperature, on the drawability of 22MnB5 steel was analyzed through the FE model. The results indicate that increasing the temperature of punch, die and holder all can improve the drawability of 22MnB5 steel. But the effect of the die temperature is the most significant while effect of punch temperature is not so pronounced. The effect of geometric parameters, including punch radius, die radius and corner radius, was also investigated. It has been found large dimension of punch and die radiuses have a positive effect on the drawability of 22MnB5 steel; a great corner radius can improve the antiwrinkle performance of the corner region.
