[0025] 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.

[0026] This utility model provides a punching device, such as Figure 1 , Figure 4 and Figure 5 As shown, it includes a work plate 1, a drop hole 19 is provided on the work plate 1, and symmetrical grooves 4 are provided on the work plate 1. Each groove 4 is equipped with a fixing mechanism. A support column 2 is fixedly connected to the top of the work plate 1, and a mounting plate 3 is fixedly connected to the top of the support column 2. A punching mechanism is provided on the mounting plate 3.

[0027] The fixing mechanism includes a first slide rod 5, with both ends of the first slide rod 5 fixedly connected to the inner walls of both sides of the slide groove 4. A clamping block 6 is slidably connected to the side surface of the first slide rod 5. The side surface of the clamping block 6 is slidably attached to the inner wall of the slide groove 4. A rubber pad 7 is fixedly connected to one side of the clamping block 6. A threaded hole is provided on the clamping block 6.

[0028] The fixing mechanism also includes a threaded shank 8, which is screwed into the inside of a threaded hole. A rubber sheet 9 is movably connected inside the threaded hole. The top of the rubber sheet 9 is in contact with the bottom of the threaded shank 8, and the bottom of the rubber sheet 9 is in contact with the bottom inner wall of the groove 4.

[0029] When using this device, the car workpiece needs to be placed on the work plate 1 first. After the workpiece is placed, the operator needs to slide the two clamping blocks 6 so that the two clamping blocks 6 move toward the workpiece and clamp it. After the clamping blocks 6 clamp the workpiece, the threaded handle 8 needs to be rotated. The threaded handle 8 can squeeze the rubber sheet 9 due to the thread engagement, so that the rubber sheet 9 is in close contact with the bottom inner wall of the slide groove 4 to obtain greater friction, thereby stably fixing the workpiece and effectively reducing the possibility of the workpiece moving during the punching process.

[0030] The rubber pad 7 provides a cushioning effect when the clamping block 6 holds the workpiece, reducing the possibility of wear caused by the clamping block 6 rubbing against the workpiece surface.

[0031] Furthermore, in order to reduce the possibility of workpiece deformation, such as Figure 1 , Figure 2 and Figure 3 As shown, the punching mechanism includes a mounting bracket 10, the bottom of which is fixedly connected to the top of the mounting plate 3. A cylinder 11 is fixedly connected inside the mounting bracket 10. The movable end of the cylinder 11 passes through the mounting plate 3 and is fixedly connected to a movable plate 12. A punch 13 is fixedly connected to the bottom of the movable plate 12.

[0032] The punching mechanism also includes a second slide rod 15, which is slidably connected to the moving plate 12. A contact plate 17 is fixedly connected to the bottom end of the second slide rod 15, and a spring 16 is sleeved on the side surface of the second slide rod 15.

[0033] The mounting plate 3 has a through hole 18, and the contact plate 17 has a stamping hole 20.

[0034] The mounting bracket 10 provides a stable guarantee for the operation of the cylinder 11. When punching the workpiece, the cylinder 11 needs to be started. The output end of the cylinder 11 can directly drive the moving plate 12 to move. When the cylinder 11 drives the moving plate 12 to move down, the punch 13 and the contact plate 17 will also move synchronously. When the contact plate 17 comes into contact with the workpiece, the cylinder 11 will continue to work. At this time, the spring 16 will be compressed, the second slide rod 15 will move on the moving plate 12, and the punch 13 will continue to move down and gradually approach the workpiece through the punching hole 20 until the punch 13 completes the punching work on the workpiece.

[0035] The contact plate 17 is designed to increase the force-bearing area of ​​the workpiece, thereby reducing the possibility of deformation of the workpiece due to excessive local force. The mounting plate 3 has a through hole 18 to provide movement space for the second slide bar 15, so as to ensure that the punching operation can be carried out normally.

[0036] After the punching operation is completed, the cylinder 11 needs to be controlled to drive the punch 13 to reset. During this process, the spring 16 will gradually release the pressure. After the contact plate 17 is separated from the workpiece, the contact plate 17 will return to the initial position under the action of the spring 16.

[0037] It should be noted that, in order to reduce the possibility of the moving plate 12 shaking or shifting, such as Figure 1 , Figure 2 and Figure 3 As shown, the bottom of the mounting plate 3 is connected to a limiting rod 14, which passes through the movable plate 12.

[0038] Two limit rods 14 are provided. During the process of the cylinder 11 driving the moving plate 12 to move, the limit rods 14 can provide a stable guarantee for the moving plate 12, reduce the possibility of the moving plate 12 shaking or deviating, and thus ensure the accuracy of punching.

[0039] When using this device, the car workpiece needs to be placed on the work plate 1 first. After the workpiece is placed, the two clamping blocks 6 need to be slid to move towards the workpiece and clamp it. After the clamping blocks 6 clamp the workpiece, the threaded handle 8 needs to be rotated so that the rubber sheet 9 is pressed tightly against the bottom inner wall of the slide groove 4 to obtain greater friction and thus stably fix the workpiece. When punching the workpiece, the cylinder 11 needs to be activated. The output end of the cylinder 11 can directly drive the moving plate 12 to move. When the cylinder 11 drives the moving plate 12 to move down, the punch 13 and the contact plate 17 will also move synchronously. When the contact plate 17 comes into contact with the workpiece, the cylinder 11 will continue to work. At this time, the spring 16 will be compressed, the second slide rod 15 will move on the moving plate 12, and the punch 13 will continue to move down and gradually approach the workpiece through the punching hole 20 until the punching workpiece is completed. The material that falls off after punching the workpiece will fall to the bottom of the work plate 1 through the drop hole 19.

[0040] 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.
