铜拉链拉头整形模设计

Design of Sizing Die for the Pull Head of the Copper Zipper

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。

The head of copper zipper pull processing technology, after blanking, bending andfoldind is forming. Made at 2.7 ± 0.05 mm of inverted U glyph of space, the forming of the2.60-0.15× 4.3mm × 63° 10＇article V. Forming article V to pull head shape after the center line ofsymmetry, because the zipper production is big, price is cheap, so the copper pull head pressingforming is a crucial process. Instead of just 0.05 mm from both sides of the unilateral clearance,the pull head will be inverted U the whole forming V. Supporting block can be used to supporthead, platen is depend on the rubber elastic light pressure head, and need to be completelypositioning. Then, under the effect of inclined block around, make left and right sides is installedon the slider around squeeze board, will U a whole forming V. This effect not only has highforming efficiency, sizing forming good symmetry, sizing of high quality and cheaper prices.
