简介:在一种零件上设计有许多对称相同的弯曲结构件,采用斜楔式顺序弯曲模一次弯曲成形。侧弯曲凸模在侧弯曲凸模凸轮压块的楔面作用下顺序进入凹模冲压成型。然后在凸轮滑动块拉杆的作用下带动侧弯曲凸模凸轮滑动块滑动,使侧弯曲凸模在弹簧作用下复位。

简介:铜拉链的拉头加工工艺,在冲裁、弯形和对折弯形后整形。使处于2.7±0.05mm空间中的倒U字形条,整形成2.60-0.15×4.3mm×63°10'的V字形条。整形后V字形条要与拉头外形的中心线对称,由于拉链的产量大,价格便宜,故铜拉头冲压整形是关键性的工序。而要从两边仅为0.05㎜的单边间隙中,将倒U字形条整形成V字形条。可采用支承块支撑拉头,压板是依靠橡皮弹力轻压拉头,并需要进行完全定位。然后,在左右斜块作用下,使安装在左右滑块上左右挤板产生挤压,将U字形条整形成V字形条。这种整形成形效果不仅使成形的效率高,而且是整形成形的对称性好,整形的质量高、价格便宜。
