[0035] For example Figure 7 -example Figure 9 Shown:
[0036] Wherein, the rebound device a1 is mainly composed of a return spring a11, a movable rod a12, and a blocking block a13. The return spring a11 is fixed on the outer position of the movable rod a12. The other end of the movable rod a12 is in clearance fit with the movable block a2, and the blocking block a13 is embedded and fixedly connected with the movable rod a12. The trajectories match.
[0037] Wherein, the front end of the rubber block a3 is provided with rubber bumps a31, and the rubber bumps are provided with thirty-six, and are evenly distributed on the front end surface of the rubber block a3, which can strengthen the surface of the rubber block a3 and the lifting rod 613. friction, thereby improving the cushioning effect of the buffer mechanism 616 on the lifting rod 613 .
[0038] Wherein, the rubber bump a31 is mainly composed of a stress groove a311, an elastic segment a312, and a concave-convex con...

Abstract
The invention discloses a punching and blanking mold, which comprises a mold, an upper mold base, a convex plate, a base, a guide sleeve, a concave mold plate, a guide post, a punching punch, and a concave mold groove. At the upper end position, the convex formwork is embedded and connected with the upper die base, and the base is fixed at the lower end of the mold. There are three die grooves on the concave formwork. When the punching punch on the convex formwork processes the material on the concave formwork, the punching The hole punch exerts pressure on the lifting plate, so that the parts separated from the material fall into the groove of the die, and the round roller on the movable block fits the surface of the lifting rod, so that the lifting rod is more stable when it is lowered, and when the processing is completed Finally, an upward force is transmitted through the spring in the conduit, which can make the lifting rod rise upwards, so that the lifting plate connected to the lifting rod drives the parts to rise upward, and the rising speed of the lifting rod can be slowed down by the rubber block on the buffer mechanism.
Description
technical field [0001] The invention relates to the field of molds, in particular to a punching and blanking mold. Background technique [0002] The punching and blanking die is a pressure processing method that uses the mold on the pressure device to apply pressure to the material to separate the parts from the material, thereby obtaining the required parts. The punching and blanking die can be used for punching, blanking, Forming processes such as bending and deep drawing, based on the above description, the inventors found that the existing punching and blanking die mainly has the following deficiencies, for example: [0003] During the processing of the punching and blanking die, since the stamped parts fall into the groove of the die and fit closely with the inner wall of the die groove, when the whole part is tilted during the removal process, it is easy to cause the parts to be stuck in the die The situation in the groove will affect the processing process to a certa...
