现行的管子封口工艺一般均采用在车床上用无刃车刀,利用摩擦力来挤压成形,从而达到封口的目的。但我厂在加工图1所示的零件时,由于工件管壁较薄,而用无刃刀单向挤压成形,一定要克服纵向、横向两种力,其中纵向力可以用内定位挡块克服,要克服横向力只有增大夹紧力,但夹紧力增大后,会引起工件变形(材料外径最大加工余量只有0.26mm),因此如
The current tube sealing process are generally used in the lathe with a non-edge turning tool, the use of friction to squeeze forming, so as to achieve the purpose of sealing. But I plant in the processing of parts shown in Figure 1, due to the workpiece wall is thin, and one-way extrusion with no blade, be sure to overcome the vertical and horizontal two kinds of force, which longitudinal force can be used to locate the stopper To overcome, to overcome the lateral force only increases the clamping force, but the clamping force increases, it will cause the workpiece deformation (material maximum allowance for the outer diameter of only 0.26mm), so
