Abstract: The automotive reinforcement-seat with complicated shape and high forming precision was formed by piercing, trimming, drawing, flanging, sizing, side trimming and cutting. Through analyzing the stamping process and scheme of the automotive reinforce-ment-seat, it was detemined that the left and right automotive reinforcement-seats were fomed in the same die with the double-row layout and intermediate carrier, and the progressive stamping process with eleven positions were put forward. Then, the side trimming, feeding mechanism and whole die structure were analyzed, and the multi-position progressive die was manufactured based on the above design scheme. After the die is tested, the results show that the layout scheme and the die structure are reasonable and feasible. Thus, the di-mensional precision of part meets the drawing requirement, which meets the requirement of mass production.
Key words: automotive reinforcement-seat; multi-position progressive die; stamping; layout; inclined wedge trimming; carrying mechanisms

模制造。目前，世界上许多超大型汽车制造企业，其冲压件约有30%~40%是用多工位连续模制造的。随着计算机技术以及加工工艺的发展，可以设计、制造出形状更加复杂和精度更高的零件，促使汽车结构件连续模也向着大型化、复杂化的方向发展[1-3]
