Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Reference Figure 1-Figure 3 A punching device for processing hardware accessories includes a machine base 1 and a platform 15. A support column 2 is welded on the top of the machine base 1. A switch 4 is arranged on the outer wall of the support column 2. A support platform 5 is welded on the inner wall of the support column 2. A box body 1 is fixedly connected to the right side wall of the support platform 5. A hydraulic cylinder 3 is fixed in the box body 1. A detachable punch is fixed to the end of the driving shaft of the hydraulic cylinder 3 by bolts. A No. 1 gear 6 is installed in the box body. A sawtooth 1 meshing with the No. 1 gear 6 is arranged on the right side wall of the hydraulic cylinder 3. A push plate 7 located on the right side of the No. 1 gear 6 and meshing with the sawtooth 1 is arranged in the box body 1. A movable connecting rod 8 is inserted into the outer wall of the box body 1 for sliding. The upper and lower ends of the push plate 7 are respectively integrally formed with extended edges located on the upper and lower sides of the end of the movable connecting rod 8. The extended edges are contacted with the movable connecting rod 8 to push and move. A box body 2 is fixed on the lower side wall of the machine base 1. A meshing No. 2 gear 19 and a No. 3 gear 20 are installed in the box body 2. The end of the movable connecting rod 8 The end is slidably inserted on the outer wall of the second box body and is fixedly connected with a power tooth 22 meshing with the second gear 19. A lower die 13 is provided on the upper side wall of the machine base 1, and a support plate is placed in the lower die 13. A pushing column 21 with an upper end located in the lower die 13 is slidably inserted on the lower side wall of the machine base 1. The left side wall of the pushing column 21 is provided with a sawtooth 2 meshing with the third gear 20. An opening is provided on the outer wall of the box body one, and a guide rod is fixedly connected in the opening. The movable connecting rod 8 is slidably sleeved on the outer wall of the guide rod. The workpiece material is placed on the lower die 13, the movable plate 12 and the raw material position are manually moved, and then the fastening screws 14 are unscrewed to fix the movable plate 12. The switch 4 is manually started, and the driving end of the hydraulic cylinder 3 starts to move toward the raw material direction. The punch contacts the raw material and pushes the raw material into the lower die 13, so that the material is separated or plastically deformed, thereby obtaining the required parts in the lower die 13. When the driving end of the hydraulic cylinder 3 shrinks upward, the stamping is completed.

[0019] When the hydraulic cylinder 3 completes the stamping, the driving end of the hydraulic cylinder 3 is retracted, and the serrations on the driving end drive the No. 1 gear 6 to rotate, and the No. 1 gear 6 drives the push plate 7 to move downward, and the extended edge of the push plate 7 contacts the end of the movable connecting rod 8, causing it to move downward, and at the same time the movable connecting rod 8 moves downward and drives the flat plate 10 to move downward.

[0020] The upper side wall of the platform 15 is fixedly connected to a vertically arranged shaft column 9, the upper end of the shaft column 9 is rotatably connected to a balance bar 18, a metal ball 17 is arranged at the end of the balance bar 18, a buffer spring 16 is fixedly connected between the balance bar 18 and the shaft column 9, and a plurality of flat plates 10 are fixedly connected to the inner side wall of the movable connecting rod 8, the end of the flat plate 10 is located on the upper side of the end of the balance bar 18, and the flat plates 10 are evenly spaced. When the flat plates 10 are in contact with the balance bar 18, the metal ball 17 moves upward, and the buffer spring 16 is in a stretched state. When the flat plates 10 are out of contact with the balance bar 18, under the reverse elastic force of the buffer spring 16 and the gravity of the metal ball 17, the balance bar 18 is The left end of the lower die 13 rotates downward, and the metal ball 17 falls and contacts the lower die 13, knocking the lower die 13 to vibrate. Through the contact between the multiple flat plates 10 and the end of the balance bar 18, the balance bar 18 rotates intermittently, and the metal ball 17 knocks the lower die 13 intermittently, and the vibration loosens the molded part. While the movable connecting rod 8 moves upward, the power tooth 22 drives the second gear 19 to rotate, and the engagement of the second gear 19 with the third gear 20 drives the third gear 20 to rotate, and then the engagement of the third gear 20 with the second sawtooth drives the push column 21 to move upward, realizing the process of pushing the column 21 upward to eject the molded part after the metal ball 17 knocks the lower die 13 to loosen the molded part. After the action is completed, you only need to manually pick up the molded part, and there is no need to manually take out the molded part from the lower die 13, which greatly improves the stamping efficiency.

[0021] A clamping frame 11 is fixedly provided on both sides of the lower die 13, and a movable plate 12 is slidably provided in the clamping frame 11. The upper side wall of the clamping frame 11 is threadedly connected with a fastening screw 14 for fixing the movable plate 12. After the workpiece material is placed on the lower die 13, the movable plate 12 is manually moved to contact the workpiece material, and then the fastening screws 14 are unscrewed to fix the movable plate 12 to prevent the workpiece material from moving outward, thereby ensuring the stability of the workpiece material during the stamping process.

[0022] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
