对于圆筒形拉深件(图1)在拉深后通常要进行切边加工。过去常采用车削、专用切边机进行加工,切边后口部质量较差、毛刺较大、工件高度一致性差、生产效率低。现介绍一种旋转式切边模(图2)。该模具在切边间隙合理、刃口锋利的情况下,切边质量好、毛刺小、工件高度一致性好、效率高 For cylindrical parts (Figure 1) after the drawing is usually carried out trimming. In the past, turning and special trimming machines were used for machining. The quality of the mouth after trimming was poor, the burrs were large, the workpiece consistency was poor, and the production efficiency was low. Now introduce a rotary trimming die (Figure 2). The mold in the trimming gap is reasonable, cutting edge sharp case, the trimming of good quality, small burr, the workpiece is highly consistent, high efficiency
