加工方法概要本加工法采用图a所示的弯曲模。弯曲模有四个工位,安装在通用的板料折弯压力机上进行工作。对应滑块上下运动,从第一工位开始按所定送进长度把板料顺次断续地送入模具内。第一工位和第二工位进行U成形,接着第三工位和第四工位进行O成形。这里,第一工位和第三工位的模具在纵向有一定倾斜,这是此加工方法的特点。在第一、三工位,当滑块到达行程的下死点时,由于上模和下模的实际成形行程是连续变化的,
Processing Method Summary This method uses the bending die shown in Figure a. The bending die has four stations, mounted on a universal sheet bending press for work. Corresponding to the slider up and down movement, starting from the first station according to the length of the feed into the intermittent intermittent feeding into the mold. The first station and the second station are U-formed, followed by O-forming at the third station and the fourth station. Here, the mold of the first station and the third station is tilted in the longitudinal direction, which is characteristic of this processing method. In the first and third stations, when the slider reaches the bottom dead center of travel, the actual forming stroke of the upper and lower dies continuously changes,
