我厂某产品中有一用角钢(20×20)弯制而成的工件(图1)。R8处弯度原来加工工序为锯割缺口、弯曲、补焊、打磨、修整,工序多而外观差。为此,我们制作了简易折弯夹具(图2)。使用时将固定弯杆7夹持在台虎钳上,并使活动弯杆3与共成一直线。将被弯工件端面与活动杆3上的定位刻线对齐,用几个夹块来夹紧,其中固定弯杆上的夹块可稍松,以便角钢在弯曲过程中移动。准备好后,手握加力管沿 I plant a product with a angle (20 × 20) bent from the workpiece (Figure 1). R8 Department of the original bending process for cutting the gap, bending, welding, grinding, trimming, processes and more and poor appearance. To this end, we made a simple bending fixture (Figure 2). When used, the fixed bending rod 7 is clamped on the bench vise, and the movable bending rod 3 and the common line are formed. Align the end face of the bent workpiece with the alignment mark on the movable rod 3, and clamp it with several clamps. The clamp on the fixed bent rod can be slightly loose so that the angle steel can move during bending. When ready, hold the force tube along
