[0024] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. Figure 1-Figure 5 The present invention is described in detail with reference to the embodiments.

[0025] A hole-punching machine for processing metal chains includes a workbench 1, on which an intermittent conveyor belt 2 is movably arranged. The intermittent conveyor belt 2 is preferably a chain plate conveyor belt or a cut-resistant conveyor belt. Two sprocket rollers 17 are rotatably arranged on the workbench 1. The two sprocket rollers 17 are rotatably connected to the intermittent conveyor belt 2, and one of the sprocket rollers 17 is arranged at the output end of a servo motor 18. Starting the servo motor 18 can drive the sprocket roller 17 to rotate, thereby rotating the intermittent conveyor belt 2 and driving the other sprocket roller 17 to rotate at the same time, thereby realizing the transmission of the intermittent conveyor belt 2. Under the control of the control panel 19, the intermittent conveyor belt 2 can realize intermittent transmission according to a preset plan and be used in conjunction with other structures.

[0026] A support plate 3 is provided on the workbench 1. There are two support plates 3, namely a vertical plate and an L-shaped plate. A control panel 19 is provided on one of the support plates 3. An adjustment plate 4 and a limit plate 5 are provided on the inner side wall of the support plate 3 of the L-shaped plate. A plurality of one-to-one corresponding adjustment slots 6 and limit slots 7 are respectively provided inside the adjustment plate 4 and the limit plate 5. The adjustment plate 4 and the adjustment slot 6 can adjust the distance between the hole-punch head 11 and the metal, and realize precise cutting under the preset scheme of the control panel 19. The limit plate 5 and the limit slot 7 can limit the adjustment rod 10 when punching a hole to prevent it from shaking left and right, thereby enhancing stability during hole punching.

[0027] A plurality of telescopic rods 12 are fixedly provided on the top wall of the support plate 3. The number of the adjusting slots 6, the limiting slots 7 and the telescopic rods 12 is the same and corresponds to each other one by one. The number of telescopic rods 12 used at the same time and the number of holes opened at the same time can be determined according to the width of the metal, which has high flexibility.

[0028] A supporting ring 8 is provided inside the adjusting slot 6, and an elastic ring 9 is fixedly provided on the top of the supporting ring 8. The elastic ring 9 is a compression spring, and an adjusting rod 10 is movably provided inside the elastic ring 9. The adjusting rod 10 moves downward, driving the elastic ring 9 to compress downward. When the compression spring is compressed to the extreme, the bottom end of the hole-punching head 11 just contacts the intermittent conveyor belt 2, that is to say, the hole-punching head 11 can just cut and punch holes in the metal.

[0029] The cross-sections of the adjusting slot 6, the limiting slot 7 and the adjusting rod 10 are all circular, and the circular diameter of the adjusting rod 10 is smaller than the limiting slot 7, and the limiting slot 7 is smaller than the adjusting slot 6. The adjusting rod 10 can be movably placed inside the elastic ring 9, and the limiting slot 7 can limit the up and down movement trajectory of the adjusting rod 10 to enhance stability.

[0030] A circle of limiting ring 14 is fixedly provided on the outer wall of the adjusting rod 10, a hole-punching cutter head 11 is fixedly provided on the bottom wall of the adjusting rod 10, and a fixed pressure ring 13 is fixedly provided on the bottom end of the telescopic rod 12. The fixed pressure ring 13 is adapted to the top end of the adjusting rod 10. The outer diameter of the limiting ring 14 is larger than the outer diameter of the elastic ring 9, so that the limiting ring 14 can always remain at the top end of the elastic ring 9. The adjusting rod 10 and the hole-punching cutter head 11 can both pass through the limiting slot 7.

[0031] The distance that the telescopic rod 12 is extended and retracted each time is preset on the control panel 19, so that it drives the fixed pressure ring 13 to move downward, and the fixed pressure ring 13 presses the adjusting rod 10 and moves downward at the same time. The downward movement of the limit ring 14 can drive the elastic ring 9 to achieve compression, so that the hole-punching head 11 cuts and punches the metal. After the hole is punched, the telescopic rod 12 moves up to its original position, and the adjusting rod 10 retracts into the adjusting slot 6 and the limit slot 7 under the rebound action of the elastic ring 9, avoiding the hole-punching head from being exposed to the outside, thereby improving safety.

[0032] The hole-punching cutter head 11 is a vibrating cutter head and includes an outer cutter head 20 and an inner cutter head 21. Both the outer cutter head 20 and the inner cutter head 21 can be set to any shape and can punch chains and holes of any shape. The outer cutter head 20 can cut a number of metal rings from a metal plate. After polishing, the several metal rings can be connected to form a metal chain. The inner cutter head 21 can punch holes in the metal rings. Outer cutter heads 20 and inner cutter heads 21 with different structural shapes can be prepared to form different adjustment rods 10 as model rods. According to actual production needs, different adjustment rods 10 can be flexibly placed inside the elastic ring 9 for flexible hole punching. Replacement is quick and convenient, and metal rings of different shapes can be flexibly cut and holes can be punched at one time.

[0033] A group of telescopic rods 15 are symmetrically arranged below the limit plate 5. The group of telescopic rods 15 are respectively fixed on the inner walls of the two support plates 3. The telescopic ends of the group of telescopic rods 15 are fixed with push plates 16. The group of push plates 16 can fix the metal plate. The telescopic rods 12 and 15 are both electric telescopic rods.

[0034] When the intermittent conveyor belt 2 is paused, a set of telescopic rods 15 is started to drive a set of push plates 16 to clamp and fix the metal plate to maintain stability during cutting and punching. After cutting is completed, a set of telescopic rods 15 is retracted and the intermittent conveyor belt 2 is conveyed again, and this is repeated.

[0035] The control panel 19 is electrically connected to the telescopic rod 12, the telescopic rod 2 15, the servo motor 18 and the hole-punching cutter head 11. The operation plan for each step of the hole-punching can be reset in the control system inside the control panel 19. According to the operation steps, the various parts are coordinated with each other to realize automatic hole-punching and improve the production efficiency of the metal chain.

[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
