[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-3 In this embodiment of the present invention, a punching device for processing angle steel towers includes a workbench 1. An adjustment mechanism is installed on one side of the workbench 1. A drive mechanism is installed at the bottom center of the workbench 1. Two sliding frames 8 located at the top of the workbench 1 are connected to the top of the drive mechanism. A hydraulic pusher 9 is installed on the inclined plate of the sliding frame 8. A punching head 10 is fixedly installed at the output end of the hydraulic pusher 9. A support frame 2 for supporting angle steel 15 is installed at the top center of the workbench 1. A waste trough 11 with an inclined bottom wall is opened at the bottom of the support frame 2 at the top of the workbench 1. A clamping mechanism for clamping angle steel 15 is installed at the top of the workbench 1.

[0019] In this embodiment: First, the angle steel 15 is placed on the support frame 2. Then, the clamping mechanism is activated to fix the current position of the angle steel 15. The adjustment mechanism is adjusted according to the drilling spacing. After the adjustment is completed, the adjustment mechanism is fixed. Then, the hydraulic push cylinder 9 is activated. The hydraulic push cylinder 9 drives the punching head 10 to punch holes in the angle steel 15. The waste material formed by the punching falls into the waste trough 11 through the corresponding slot on the support frame 2 and slides outward along the bottom of the inner wall of the waste trough 11. Then, the drive mechanism is activated. The drive mechanism moves according to the adjustment mechanism. After the movement is completed, the second hole is opened. In the above process, the two hydraulic push cylinders 9 are operated alternately by the switch to avoid the two punching heads 10 from interfering with each other.

[0020] By designing an adjustment mechanism, the distance between the two openings can be effectively adjusted.

[0021] Please refer to this carefully. Figure 1 and Figure 2The clamping mechanism includes four guide rods 3 fixedly installed on the top of the workbench 1. The top of the four guide rods 3 is fixedly connected to a mounting plate 4. An electric push cylinder 5 is installed at the top of the mounting plate 4. The piston rod of the electric push cylinder 5 extends through to the bottom of the mounting plate 4. An upper sliding plate 6 is fixedly installed at the bottom of the piston rod of the mounting plate 4. The bottom of the upper sliding plate 6 is connected to a lower sliding plate 7 through a buffer assembly. The center of the lower sliding plate 7 is in contact with the outer wall of the angle steel 15. The buffer assembly includes a sliding rod 19 extending from above the upper sliding plate 6 to below the upper sliding plate 6. The bottom of the sliding rod 19 is fixedly connected to the top of the lower sliding plate 7. A spring 20 that is sleeved with the sliding rod 19 is installed between the bottom of the upper sliding plate 6 and the top of the lower sliding plate 7.

[0022] In this embodiment: after the angle steel 15 is placed, the electric push cylinder 5 is activated, which pushes the upper sliding plate 6 downward. The upper sliding plate 6 then pushes the lower sliding plate 7 downward through the sliding rod 19 and the spring 20. The lower sliding plate 7 moves downward and presses the angle steel 15. At this time, the lower sliding plate 7 cannot move downward, while the upper sliding plate 6, which continues to move downward, moves downward relative to the sliding rod 19 and presses the spring 20. The spring 20 is compressed, and the restoring force generated after the spring 20 is compressed acts on the top of the lower sliding plate 7, effectively pressing the angle steel 15.

[0023] Please refer to this carefully. Figure 2 The drive mechanism includes two fixed ears fixedly installed at the bottom of the worktable 1. A screw 17 is rotatably installed between the two fixed ears. A translation plate 16 is threadedly connected to the outer wall of the screw 17. Both ends of the translation plate 16 penetrate into the interior of the worktable 1 and are fixedly connected to the bottom of the two sliding frames 8. A strip groove is provided inside the worktable 1 for the translation plate 16 to slide.

[0024] In this embodiment: after the first drilling is completed and before the second drilling is performed, the drive mechanism is activated. The forward and reverse motor 18 installed at one end of a fixed lug drives the screw 17, which is fixedly connected to it on the same axis, to rotate. The rotating screw 17 drives the translation plate 16 to slide along the strip groove. The translation plate 16 can then move by driving the two sliding frames 8 and the hydraulic push cylinder 9 installed on the sliding frames 8.

[0025] Please refer to this carefully. Figure 2 and Figure 3The adjustment mechanism includes a fixed plate 12 fixedly installed on one side of the workbench 1, a movable plate 14 slidably installed on one side of the workbench 1, a slide groove 13 for the movable plate 14 to slide on one side of the workbench 1, a locking bolt 24 threadedly connected to the movable plate 14 and abutting against the inner wall of the slide groove 13, and an infrared transmitter 21 fixedly installed on one side of the translation plate 16, an infrared receiver 22 installed inside the fixed plate 12, and a second infrared receiver 23 installed inside the movable plate 14. The infrared transmitter 21 and the second infrared receiver 23 are electrically connected to the forward and reverse motor 18 through a PLC controller.

[0026] In this embodiment: when it is necessary to adjust the distance between two holes, first loosen the locking bolt 24. After the locking bolt 24 is loosened, the moving plate 14 can be pushed to slide along the slide groove 13 until the distance between the fixed plate 12 and the moving plate 14 meets the distance between the two holes (which can be determined by measuring with a ruler). After the position of the moving plate 14 is determined, tighten the locking bolt 24 again to fix the moving plate 14 in the current position.

[0027] After a drilling operation is completed, the driving mechanism is activated, and the moving translation plate 16 drives the infrared transmitter 21 to move synchronously until the infrared transmitter 21 is aligned with the second infrared receiver 23. At this time, the infrared signal emitted by the infrared transmitter 21 is received by the second infrared receiver 23. The second infrared receiver 23 then sends an electrical signal to the controller, which controls the forward and reverse motor 18 to stop moving.

[0028] After the second drilling is completed, the drive mechanism is started, driving the translation plate 16 to reset. The translation plate 16 then drives the infrared transmitter 21 to move synchronously until the infrared transmitter 21 is aligned with the first infrared receiver 22. At this time, the infrared signal emitted by the infrared transmitter 21 is received by the first infrared receiver 22. The first infrared receiver 22 sends an electrical signal to the controller, and the controller controls the forward and reverse motor 18 to stop running.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
