厂家在操作钣金加工自由拔缘的方法

所谓自由拔缘是钣金加工中通用的拔缘工具,在板料上进行拔缘,基本程序如下:

(1)将拔缘毛坯边缘上的毛刺锉光。

(2)在毛坯上划出拔缘的宽度线。

(3)在铁毡上用锤子敲打进行拔缘。

外拔缘,先弯边,后再万变上打出波折,再打平波折,使弯边收缩成凸边。

内拔缘,是用放边的方法制成弯边,在拔缘时,因材料延伸,易产生裂纹,在拔缘前要用砂纸打光边缘。在边缘过程中如产生裂纹,要用剪刀剪切裂纹,用砂纸大关后在拔缘。

The so-called free pull edge is a universal edge removal tool in sheet metal processing. The basic procedures are as follows:

(1) to file the burr on the edge of the blank.

(2) the width line of the drawing edge is drawn out on the blank.

(3) strike the edge with a hammer on the iron felt.

Pull out the edge, bend the edge first, then change the curve, then beat the flat wave to make the curved edge shrink into a convex edge.

The internal pulling edge is made by bending the edges. When the edge is drawn, the material is easy to crack. If cracks occur in the edge process, scissors should be used to cut the cracks, and then use the sandpaper to mark the edge.
