CP—20卡槽零件一次滚弯成形

ONE-STEP ROLL FORMING OF CP-20 CHANNEL SECTION PART

介绍了在自制简易滚床上，改进滚模设计，替代原滚边──折弯相结合的工艺方法，实现一次滚弯成形。改进后的成形方法，保证了产品质量，提高工效8倍，原材料也得到充分利用。

This paper introduces the technique of modified folling die to make one-step roll forming instead of initial crimping-folding process on a self-made simply-constructed roller modified. Themodified process ensure product quality, increases work efficiency by eight times and makes full use of raw materials.
