The punching mechanism 3 includes a hydraulic cylinder 301 fixedly connected to the frame 2. A punching seat 302 is fixedly connected to the output end of the hydraulic cylinder 301. A fixed punch 303 is fixedly connected to the center of the punching seat 302. Adjustable movable punches 304 are provided on both sides of the fixed punch 303.

[0032] By adopting the above technical solution, it is possible to simultaneously fix the metal chain plate while punching holes in it, thereby increasing the convenience and stability of punching the metal chain plate. At the same time, it is easy to adjust the movable punch 304, so the distance between the movable punch 304 and the fixed punch 303 can be adjusted, thus improving the practical flexibility of this utility model.

[0033] The side of the punching seat 302 is provided with an adjustment groove 3041. An adjustment bolt 3042 is rotatably mounted on the side of the inner wall of the adjustment groove 3041 via a bearing. An adjustment sleeve 3043 is threaded onto the adjustment bolt 3042. The bottom of the adjustment sleeve 3043 is fixedly connected to the top of the movable punch 304 via a connecting block 3044. By rotating the adjustment bolt 3042, and under the action of the thread of the adjustment sleeve 3043, the movable punch 304 at the bottom of the connecting block 3044 is driven to adjust its position, thereby adjusting the distance between the movable punch 304 and the fixed punch 303. A limit bearing 30421 is installed on the side of the punching seat 302 at the position corresponding to the adjustment bolt 3042, and is rotatably connected to the adjustment bolt 3042. By setting the limit bearing 30421, the adjustment bolt 3042 is limited, thereby increasing the stability of the rotation of the adjustment bolt 3042.

[0034] The top of the adjusting screw sleeve 3043 is fixedly connected to the limiting slider 30431. The inner wall of the adjusting groove 3041 is provided with a limiting groove 30432 that matches the limiting slider 30431. By setting the limiting slider 30431 and the limiting groove 30432, the adjusting screw sleeve 3043 is limited, thereby increasing the stability of the sliding adjustment of the adjusting screw sleeve 3043. Both sides of the bottom of the punching seat 302 are equipped with clamping and fixing components 305 for clamping and fixing the metal chain plate to be punched.

[0035] The clamping and fixing assembly 305 includes a mounting shell 3051 fixedly connected to the bottom of the punching seat 302. A connecting spring 3052 is fixedly connected to the top of the inner wall of the mounting shell 3051. A connecting slider 3053 is fixedly connected to the bottom of the connecting spring 3052. A connecting slide rod 3054 is fixedly connected to the bottom of the connecting slider 3053. A clamping plate 3055 is fixedly connected to the bottom of the connecting slide rod 3054. By setting the clamping and fixing assembly 305, as the punching seat 302 moves downward, the first... First, the metal chain plate to be punched is pressed and fixed by the clamping plate 3055. Then, the metal chain plate is punched by the fixed punch 303 and the movable punch 304, which increases the stability and convenience of punching the metal chain plate. The bottom of the clamping plate 3055 is fixedly connected with an anti-slip clamping pad 30551. By setting the anti-slip clamping pad 30551, the stability of clamping the metal chain plate to be punched is increased, and damage to the metal chain plate is avoided during the clamping process.

[0036] The working principle of this utility model is as follows: First, the metal chain plate to be punched is placed on the punching table 4. Then, the punching seat 302 is moved down by the hydraulic cylinder 301. While the punching seat 302 is moving down, the metal chain plate to be punched is first pressed and fixed by the clamping plate 3055. Then, the metal chain plate is punched by the fixed punch 303 and the movable punch 304, thereby increasing the convenience and stability of punching the metal chain plate. At the same time, by rotating the adjusting bolt 3042, and under the action of the thread of the adjusting screw sleeve 3043, the movable punch 304 at the bottom of the connecting block 3044 is driven to adjust its position, thereby adjusting the distance between the movable punch 304 and the fixed punch 303, thus increasing the flexibility of this utility model.

[0037] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner.
