| Objective To determine reasonable and feasible forming solutions. Methods The forming characteristics of the thermal baffle was analyzed, and finite element software was used to conduct numerical simulation for drawing forming of the part. When designing the orthogonal experiment, BHF, full clamping force of 1 and 3 drawbeads, full clamping force of 2 and 4 drawbeads and the friction coefficient were set as the independent variables, and the maximal thickness reduction rate, rupture as well as size of insufficient deformation zone were set as the optimization targets. Results The 2nd and the 4th drawbeads were the main influencing factors of the thermal baffle forming, when both clamping forces were 60 N /mm, the thermal baffle formed better. Conclusion Optimized process parameters were obtained through analysis of the impact of various factors on the optimization targets, which provides guidance for the actual production of the part. |
