冲压件(图1)为BJ130汽车发动机前悬挂软垫盖板。 原来此冲压件的冲压工序是:落料、拉延、修边(四个边分四次切边冲压)、冲孔等四道工序。现做了一副四工序复合模(见图2),一次冲压成形,同时利用新压床的自动接料器实现连续冲压。通过近6年多的生产验证,该模具结构较为满意可行。 下面就此副模具设计中几个考虑的重点 Stamping parts (Figure 1) are BJ130 car engine front suspension cushion cover. The stamping of the original stamping process is: blanking, drawing, trimming (four edge points four times trimming punching), punching and other four processes. Are doing a four-process compound mold (see Figure 2), a stamping, while using the new automatic press feeder automatic stamping. Through nearly 6 years of production verification, the mold structure is more satisfactory. Below this deputy mold several key considerations in the design
