不对称Ｖ形件铰链式弯曲模王成璞（南京汽车附件七厂邮编２１００１２）不对称ｖ形件在弯曲过程中，往往产生滑移，孔至边的距离、弯曲角度等难以保证。一般多采用将工件夹紧或用定位销定位的方法（见图１所示），阻止工件滑移。然而，对一些呈明显不对称形状且弯曲精度要... Asymmetric V-shaped hinged bending die Wang Chengpu (Nanjing Automobile Annex VII Factory Zip Code 210012) Asymmetric v-shaped pieces in the bending process, often produce slip, hole to the edge of the distance, the bending angle is difficult to guarantee. Generally use the workpiece clamping or positioning pin positioning method (see Figure 1), to prevent the workpiece slip. However, for some clearly asymmetric shapes and bending accuracy to ...
