该发明介绍有关剪床切断圆棒料和方棒料的剪切方法,其目的是为了获得接近垂直的材料剪切断面,以使后来的加工更加容易。从前,用图1所示的剪床剪切圆棒料或方棒料时,就会像图3所示的那样,在碰上刀刃的地方产生β°的倾斜,切落材料的剪切面出现α°的倾斜,而余料的剪切面则约为90°。因此,被切下的材料就会出现图5所示的那样, This invention describes the shearing method of shear bar and square bar cuttings for the purpose of obtaining a nearly vertical shear section of material to make subsequent machining easier. In the past, when a bar or square bar was sheared with the shearer shown in FIG. 1, as shown in FIG. 3, a tilt angle of β ° occurred at a blade edge, and the shear surface of the cut material An inclination of [alpha] [deg.] Occurs, while the shear of the remainder is about 90 [deg.]. Therefore, the cut material will appear as shown in Figure 5,
