Abstract

It is found the hot forming quality has close related to the initial temperature of the pressing die, the blank, pressing speed, cooling rate and the friction between the part and tools. Through the design of orthogonal test and multiple regression analysis, the regression model of thinning rate and these factors are obtained. The model has 99% significance and credibility. By the variance analysis of independent variables and dependent variables, the confidence level is 99.91%, and the residual analysis results show a good correlation between the measured values and the calculated values. The results show that the modified model has high reliability.
