目前,有三种通用的弯曲法:V 型模弯曲和 U 型模弯曲。但另一种名为旋转弯曲的,可能成为最常用的弯曲法。已获得专利的旋转弯曲法,是由美国 Ready Tools 有限公司总经理 R.T.gargrave 推出的。旋转弯曲的基本优点是大大降低了弯曲所需的力。由于冲压弯曲最类同于旋轮弯曲,因而有必要对冲压弯曲所需的力作一番考虑。冲压弯曲必须有一个对压料板或卸料 Currently, there are three general bending methods: V-die bending and U-die bending. But another type of bending called rotation may become the most commonly used bending method. The patented spin-bending method was introduced by R. T. Gargrave, general manager of Ready Tools Inc., USA. The basic advantage of rotating bending is that the force required to bend is greatly reduced. Because stamping is most similar to bending, it is necessary to consider the force required for stamping and bending. Stamping bending must have a pressure on the board or discharge
