Abstract
The invention discloses a hook-type side punching oblique wedge mechanism which comprises a sliding block, punches, a base, an upper die holder and a lower die holder. A first slope and a second slope are respectively arranged on two sides of the bottom end of the sliding block. The sliding block is connected with the upper die holder in a sliding manner. The punches are fixedly connected with the first slope. A negative included angle is formed between each punch and the longitudinal axis of the sliding block. A third slope is arranged on the base. The base is fixedly connected with the lower die holder. The sliding block can slide to enable the second slope to be matched with the third slope. According to the invention, when the upper die holder drives the sliding block to move downwards till the second slope is in contact with the third slope, under the guiding action of the third slope, the sliding block moves left and right along the upper die holder, so that holes in the inner side of a workpiece can be punched by the punches, integral punching of the holes in the inner side of the workpiece and the workpiece is completed, the punching process of the holes in the inner side in the later period is reduced, errors caused by punching and repositioning in the later period are avoided, and the production efficiency and the punching precision are improved.
