按照现有的理论,圆盘剪剪切板材的过程被看作是两个斜剪刃的剪切过程。这种观点不能解释圆盘剪剪切板材时的一系列运动学和动力学问题。实际上,尽管圆盘剪剪切板材的过程和它的最终结果与轧制板材不同,但还是有好多共同之处的。为了确定板材的运动速度和剪切时的作用力,本文研究了板材在圆盘剪(剪刃中心线在同一个垂直平 According to the existing theory, the process by which the disc shears cut the slab is considered as the shearing process of the two diagonal cutting edges. This view does not explain a series of kinematic and kinetic problems with disc shears when shearing sheets. In fact, although the process of cutting a sheet with a disc shearer and its end result are different from those of rolling a plate, there are still many things in common. In order to determine the speed of sheet metal and shearing force, this paper studies the plate in the disc shears (cutting edge centerline in the same vertical plane
