Taking the automobile engine bracket as the research object, in order to reduce the blank when processing, three schemes were proposed according to numerical simulation result, and the optimized plan with 15% reduction of the original blank volume was determined. And on this basis, the orthogonal experiment was established to optimize the process parameters of the optimized blank. The results show that the size of blank has a major effect on the folding. The best process parameters were determined with the combination of folding angle, mold load and stress distribution and other factors. When the working speed of the press is 85 mm·s-1, the concave cavity radius is 90 mm, the blank initial temperature is 420 ℃, the friction coefficient is 0.3, the forging forming quality is better. Through the actual production verification, the qualified product was obtained.
