[0025] During specific implementation, the user can first use the stamping die head 9 to cooperate with the hydraulic cylinder 5 to perform stamping work. When the stamping die head 9 needs to be replaced, the user can first lift the pull block 22 upward to make the clamping rod 20 leave the square groove 18, so that the clamping rod 20 The limit of the docking sleeve 17 disappears, and the docking sleeve 17 is pushed at this time. During the process of pushing the docking sleeve 17 forward, the second conical block 16 will be pushed against the second conical block 16, and the second conical block 16 will be pushed toward the telescopic block 11. When one end of the second conical block 16 hits the inclined surface of the telescopic block 11, the telescopic block 11 will be pushed upward until the largest diameter of the second conical block 16 passes through the bottom end of the telescopic block 11. The telescopic block 11 will be reset by the elastic force of the reset spring 12. At this time, the second conical block 16 and the first A conical block 15 is simultaneously on the right side of the telescopic block 11. At this time, the push handle 14 is pulled to drive the round rod 13 to move. After the round rod 13 moves, the first conical block 15 will push the second conical block 16 to move to the left together. During the movement, the inclined surface of the second conical block 16 is in direct contact with the telescopic block 11, and the telescopic block 11 will also be pushed upward until the second conical block 16 and the first conical block 15 pass under the telescopic block 11 at the same time, and the telescopic block 11 will be reset. When the second conical block 16 and the first conical block 15 are simultaneously separated from the limit of the telescopic block 11, the user can also take out the round rod 13 and the docking sleeve 17 from the connecting block 8, and the stamping die head 9 is fixedly connected to the bottom of the docking sleeve 17, so the stamping die head 9 can also be easily taken out.
[0026] When installation is required, it is only necessary to restore the docking sleeve 17 and the second conical block 16 to their initial state, and then push the round rod 13 into the clamping groove 10, and the first conical block 15 will form a clamping effect with the telescopic clamping block 11 again, and the clamping of the square groove 18 and the clamping rod 20 can fully fix the stamping die head 9, and when the stamping die head 9 is used for stamping, the reaction force received by the stamping die head 9 will act more on the bottom surface of the connecting block 8 with a larger contact surface with the stamping die head 9, and will not have too much impact on the docking assembly.
[0027] By setting up the docking assembly, the connection structure between the punch die head 9 and the connecting block 8 is optimized, making the replacement process simpler and faster, which greatly shortens the replacement time of the die head, thereby improving production efficiency. At the same time, when the punch die head 9 is worn or damaged, it can be quickly replaced, avoiding the losses caused by long-term downtime for maintenance and reducing maintenance costs.
[0028] See also Figure 4 In the initial state, the second conical block 16 is arranged between the first conical block 15 and the docking sleeve 17, and the other end of the round rod 13 is fixedly connected with the push handle 14. By setting the other end of the round rod 13 to be fixedly connected with the push handle 14, the round rod 13 and the docking sleeve 17 can be pulled more easily.
[0029] See also Figure 2-4 A retaining block 19 is fixedly installed on the outer wall of the connecting block 8, and a slidable card rod 20 is installed inside the retaining block 19. A pull block 22 is fixedly installed on the top of the card rod 20. Two resistance springs 21 are fixedly connected between the bottom surface of the pull block 22 and the top surface of the retaining block 19. A square groove 18 is opened on the outer wall of the docking sleeve 17, and the square groove 18 is adapted to the card rod 20. By setting a slidable card rod 20 installed inside the retaining block 19, and setting a square groove 18 to adapt to the card rod 20, the user can clamp the square groove 18 through the card rod 20 after completing the installation of the stamping die head 9, further limit the docking sleeve 17, and prevent the docking sleeve 17 from moving back and forth. By fixing the pull block 22 on the top of the card rod 20, and fixing two resistance springs 21 between the bottom surface of the pull block 22 and the top surface of the retaining block 19, the card rod 20 will not be easily opened without human power.
[0030] See also Figure 1 A connecting plate 6 is fixedly connected to the bottom of the hydraulic cylinder 5, a connecting block 8 is fixedly installed on the bottom surface of the connecting plate 6, a guide rod 7 is fixedly installed on the bottom surface of the mounting plate 3, and the connecting plate 6 is slidably sleeved on the outer wall of the guide rod 7. By setting the connecting plate 6 fixedly connected to the bottom of the hydraulic cylinder 5 and the connecting plate 6 being slidably sleeved on the outer wall of the guide rod 7, the connecting plate 6 is more stable during the descending process.
[0031] It should be noted that the bottom surface of the telescopic card block 11 is inclined, and in the initial state, the inclined surface of the telescopic card block 11 faces the opening of the card slot 10 .
[0032] Working principle: the user can first use the stamping die head 9 to cooperate with the hydraulic cylinder 5 to perform stamping work. When the stamping die head 9 needs to be replaced, the user can first lift the pull block 22 upward to make the clamping rod 20 leave the square groove 18, so that the clamping rod 20 The limit of the docking sleeve 17 disappears, and the docking sleeve 17 is pushed at this time. During the process of pushing the docking sleeve 17 forward, the second conical block 16 will be pushed against the second conical block 16, and the second conical block 16 will be pushed toward the telescopic block 11. When one end of the second conical block 16 hits the inclined surface of the telescopic block 11, the telescopic block 11 will be pushed upward until the largest diameter of the second conical block 16 passes through the bottom end of the telescopic block 11. The telescopic block 11 will be reset by the elastic force of the reset spring 12. At this time, the second conical block 16 and the first A conical block 15 is simultaneously on the right side of the telescopic block 11. At this time, the push handle 14 is pulled to drive the round rod 13 to move. After the round rod 13 moves, the first conical block 15 will push the second conical block 16 to move to the left together. During the movement, the inclined surface of the second conical block 16 is in direct contact with the telescopic block 11, and the telescopic block 11 will also be pushed upward until the second conical block 16 and the first conical block 15 pass under the telescopic block 11 at the same time, and the telescopic block 11 will be reset. When the second conical block 16 and the first conical block 15 are simultaneously separated from the limit of the telescopic block 11, the user can also take out the round rod 13 and the docking sleeve 17 from the connecting block 8, and the stamping die head 9 is fixedly connected to the bottom of the docking sleeve 17, so the stamping die head 9 can also be easily taken out.
[0033] When installation is required, it is only necessary to restore the docking sleeve 17 and the second conical block 16 to their initial state, and then push the round rod 13 into the clamping groove 10, and the first conical block 15 will form a clamping effect with the telescopic clamping block 11 again, and the stamping die head 9 can be fully fixed by the clamping of the square groove 18 and the clamping rod 20.
[0034] By setting up the docking assembly, the connection structure between the stamping die head 9 and the device is optimized, making the replacement process simpler and faster, which greatly shortens the replacement time of the die head, thereby improving production efficiency. At the same time, when the stamping die head 9 is worn or damaged, it can be quickly replaced, avoiding the losses caused by long-term downtime for maintenance and reducing maintenance costs.
