采用旋转压模压弯金属薄板,可以不使用支承衬垫,节省动力。旋转压模包括三个部分:带有V型槽口的摆动轴、滑动座架和固定机座。开始加压弯曲时,V型槽口的两个突角接触工件。继续压弯时,摆动杆在座架内旋转,一个突角压住工件,另一个突角迫使金属薄板的外伸部分沿着固定机座弯曲。摆功杆的运动行程要比预想得到的弯曲角度稍大—些,以补偿金 Rotating the stamper to bend the metal sheet, you can save the power without the use of bearing pads. Rotary die includes three parts: a swinging shaft with V-notch, a sliding mount, and a fixed mount. When you start to press and bend, the two corners of the V-notch contact the workpiece. When bending continues, the rocking lever rotates within the frame, one corner presses against the workpiece and the other corner forces the overhang of the sheet metal to bend along the fixed base. Pole exercise stroke than the expected bending angle slightly larger - some to compensate for the gold
