[0022] Please refer to the attached Figure 1-3 A can cover stamping forming equipment comprises a support plate 1, a hydraulic rod 7 is connected and fixed to the lower surface of the support plate 1, a connecting block 3 is connected and fixed to the movable end of the hydraulic rod 7, a convex groove is arranged on the front of the connecting block, and a stamping die 6 is inserted into the convex groove, through grooves communicating with the convex groove are arranged on the left and right sides of the connecting block 3, and screws 5 are inserted into the through grooves, and a clamping plate 13 is slidably contacted on both the front and rear sides of the stamping die 6, and the clamping plate 13 is slidably contacted with the front side of the stamping die 6, and the two ends of the clamping plate 13 are respectively connected and fixed with two screws 5, and nuts 4 are slidably connected on both the left and right sides of the connecting block 3, and the nuts 4 are threadedly connected with the screws 5.

[0023] By installing the stamping die 6 in the connecting block 3, and clamping the left and right sides of the stamping die 6 through a clamping mechanism composed of a clamping plate 13, a screw 5 and a nut 4, the clamping mechanism is used to limit the position of the stamping die 6 in the convex groove, so that the replacement of the stamping die 6 is more convenient, thereby meeting the use of stamping dies 6 of different models and increasing the applicability of the device.

[0024] A plurality of circular holes penetrating the connecting block 3 are provided on the side of the stamping die 6 facing the support plate 1, and a round rod 2 is inserted into the circular hole. The end of the round rod 2 away from the stamping die 6 is connected and fixed to the support plate 1, and an L-shaped hole 10 is provided on the side of the round rod 2 away from the support plate 1. A hinged plate 8 is hinged at a corner in the L-shaped hole 10, and an elastic member 9 is connected and fixed on one side of the hinged plate 8. The elastic member 9 is a spring. The elastic member 9 is in a normal state, and the end of the elastic member 9 away from the hinged plate 8 is connected and fixed in the L-shaped hole 10.

[0025] By installing a one-way structure consisting of a hinge plate 8 and an elastic member 9 at the inner corner of the L-shaped hole 10, the one-way structure is used to enable the hydraulic rod 7 to drive the stamping die 6 to form the can cover so as to store air. When the hydraulic rod 7 drives the stamping die 6 to contract, the stored air is discharged from the side of the stamping die 6 that contacts the can cover, thereby preventing the can cover from adhering to the stamping die 6 after the stamping is completed.

[0026] In order to prevent the punching die 6 from punching the can cover and causing unevenness when the round rod 2 fails to block the round hole, a fixed abutting block 11 is connected to the bottom of the round hole, and a plurality of small holes 12 are opened on the lower surface of the abutting block 11.

[0027] The specific operation process of the utility model is as follows: the stamping die 6 is inserted into the convex groove, and the stamping die 6 is clamped by two clamping mechanisms composed of a clamping plate 13, a screw rod 5 and a nut 4 in front and behind.

[0028] The movable end of the hydraulic rod 7 extends to drive the stamping die 6 to move downward and stamp the can cover raw material. Since the round rod 2 is inserted in the stamping die 6, when the stamping die 6 moves downward, the round rod 2 moves upward in relative position in the stamping die 6. At this time, negative pressure is generated in the circular hole, and the circular hole sucks in air for replenishment through multiple small holes 12 and L-shaped holes 10 opened on the lower surface of the supporting block 11. When the stamping die 6 contacts the can cover raw material, the circular hole is only replenished with air through the L-shaped hole 10. When the can cover raw material is stamped, the movable end of the hydraulic rod 7 drives the stamping die 6 to move upward. At this time, the round rod 2 moves downward in relative position in the stamping die 6, so that the air in the circular hole is discharged through the small holes 12, and the can cover adhered to the outer surface of the stamping die 6 is separated from the stamping die 6.

[0029] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
