薄壁零件的边(口)部应先切齐再弯卷。使薄壁零件边(口)部实现切卷变形的操作的全过程即为“切卷工艺”。一、现有切卷工艺装置的几种类型 1.丝杆一螺母式切卷边。这种切卷装置可用废旧车床改装;其特点是手动进、退刀,其次是司切与司卷的两个刀架分置在主轴两侧。因此,主要工步包括:切边进刀(卷边退刀),边齐,切边退刀,卷边进刀(卷成),、切刀前 Thin-walled parts of the edge (mouth) Department should be cut before the first curl. The entire process of cutting and deforming the edge (mouth) part of the thin-walled part is the “cutting process”. First, there are several types of existing cutting process device 1. Screw a nut-type cut edge. This type of rolling device can be used to modify the old lathe; characterized by manual feed, retractable knife, followed by Secretary Division and Division two turret knife placed on both sides of the spindle. Therefore, the main steps include: trimming the edge of the knife (curled edge retraction), edge Qi, trimming edge retraction, curling into the knife (rolled into), before the cutter
