Blocking finger for bending machine

The utility model discloses a stop finger for a bending machine. The stop finger comprises a sliding seat, a base, a front stop block and a rear stop block, the base is arranged on the sliding seat, the rear check block is installed on the base, the front end of the rear check block is hinged to the rear end of the front check block, and the front end of the front check block is in a multi-step shape. By means of the arrangement, workers can conduct graded positioning according to the machining conditions of the plates, the retreating distance needed by the blocking fingers is reduced, and therefore the coping capacity of the blocking fingers for different feeding conditions is improved, and the workers can bend the metal plates conveniently. 本实用新型公开了一种用于折弯机的挡指，包括滑座、底座、前挡块和后挡块；底座设置在滑座上，后挡块安装在底座上，后挡块的前端与前挡块的后端铰接，前挡块的前端为多级台阶状；通过上述设置，工作人员可以根据板材的加工情况进行分级定位，减少挡指所需的后退距离，从而提高挡指对不同进料情况的应对能力，便于工人对金属板材折弯加工。
