补充资料:薄壁件拉深切边模
在冲压生产中,经常遇到无凸缘壁件的拉深加工,如果薄壁件形状较为复杂,在冲模设计中就要解决两个主要问题:(1)因出料要求凹模不能采用整体形状,但由于工件开头复杂,凹模需整体加工,这个矛盾在设计中应予以考虑。(2)由于拉深件下料进要留出修边量,故在拉深后应有切边工序,无论在车床上用专用夹具加工还是留修边最后磨削加工,都趣在效率低,易破坏工件外形等问题。

我厂生产的YJH256液力变矩器泵轮外环(见图1),就属于此种类型零件,为适应生产需要,设计了如图2所示的拉深模具。
 



1.下接盘 2.顶杆 3.压料板 4.导向装置 5.连接圈 6.上接盘 7.凹模板 8.压块 9.上出料装置 10.退料圈 11.上模座 12.凸模 13.下出料装置 14.切边环 15.凸模座 16下模座


工作原理:(1)顶杆2推出压料板3,压在凹模块7上。(2)凹模整体(凹模块7,连接圈5,上接盘6,压块8,退料圈10,上模座11)下降,工件成形,降至切边环刃处,切掉凸缘。(3)凹模抬起,同时油压机上缸活塞顶出,上出料装置9下压退料圈10下行,工件退出凹模。(4)下出料装置13中的弹簧顶出推杆,将切边余料从切边环上退出。

设计中的注意事项:(1)由于出料要求,凹模采用分体式,但要整体加工,故退料圈10应现与上接盘6配钻螺孔,装配后与凹模块7一起进行车削。(2)连接圈5与凹模块7制成分体式,凹模块磨损后可更换。(3)切边环采用工具钢制造,要求淬火,并采用见风使快换嵌入式。(4)此装置应带有导向机构。
