我公司以前生产的汽车车架纵梁,由于受设备和整体压模的限制,不能一次成型,只能分段压制,成型后的产品尺寸精度和形位公差均达不到要求。要制造整体压模,投资大,周期长,工艺要求高,加之车架纵梁品种多(见图1、图2、图3),更难以下手。后来经过研究与学习,设计制造了组合镶块压弯成型模,只要更换不同尺寸的镶块及镶块安装板,就能方便地压制多 The car frame longitudinal beam produced by our company can not be formed in one time due to the limitation of the equipment and the whole stamper, and the dimension precision and shape position tolerance of the finished product after molding are all less than the requirements. To create the overall die, large investment, long cycle, high process requirements, coupled with a variety of frame rails (see Figure 1, Figure 2, Figure 3), more difficult to start. Later, after research and study, the design and manufacture of a combination of insert compression bending mold, as long as the replacement of different sizes of inserts and inserts mounting plate, you can easily suppress more
