由于受结构形式的限制,角铁圆弧弯曲一直是较难解决的问题。最近,根据产品开发的需要,我厂要加工一批如图1所示的工件。如果采用热弯敲打工艺或内面割槽敲打成形法加工,其形状很不美观,尺寸也很难保证,且效率很低。为解决这一问题,我们设计了一种特殊的角铁成形模,在普通卷板机上完成了这一工件的成形,达到了理想的效果。
Due to the structure of the restrictions, angle iron arc bending has been more difficult to solve the problem. Recently, according to the needs of product development, I plant to process a number of the workpiece shown in Figure 1. If the use of hot beating or tapping process inside the beat forming process, its shape is not beautiful, the size is difficult to guarantee, and the efficiency is very low. In order to solve this problem, we designed a special angle iron forming die, which completed the forming of the workpiece on a normal coiling machine to achieve the desired result.
