[0027] 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.

[0028] See Figures 1-5 A punching device for steel structures includes a support frame 1, a base plate 2, a support rail 3, and a punching assembly 4.

[0029] The support frame 1 is assembled from steel sections connected by bolts. It is located at the bottom of the entire device and serves as the basic support structure. The base plate 2 is fixed to the top of the support frame 1 by bolts. The base plate 2 is horizontal and fits against the top plane of the support frame 1. The two are firmly connected by evenly distributed bolts. The support rail 3 and the punching assembly 4 are installed on top of the base plate 1. Its upper surface is kept flat to provide an installation plane for other components, ensuring the positional accuracy of each component after installation. At the same time, it effectively disperses the impact force during the punching process. The support rail 3 is fixed to the top upper surface of the base plate 2 by bolts and fits against the upper surface of the base plate 2. The support rail 3 is a long strip structure, parallel to the length of the base plate 2. Two support rails 3 are arranged parallel to each other. The function of the support rail 3 is to provide a support for the holes to be punched. The steel structural components provide support and guidance. In actual operation, the steel structural components are placed on the support rail 3. Relying on the guiding effect of the support rail 3, the steel structural components are ensured to maintain linear movement during the punching process, so that the punch 9 can be aligned with the punching position, thereby improving the punching accuracy. The sliding columns 5 are vertically fixed to the top of the base plate 2 by bolts. There are two or more of them, and they are evenly distributed on the base plate 2 below the horizontal plate 6. These sliding columns 5 are parallel to each other, and their vertical setting provides vertical support and guidance for the horizontal plate 6. The horizontal plate 6 can slide smoothly up and down along the axial direction of the sliding columns 5 through cooperation with them. Thus, the vertical distance between the punch 9 and the steel structural component can be flexibly adjusted according to the thickness of the steel structural component to be punched, so as to meet the needs of different thicknesses. For the punching requirements of the steel structural components, the horizontal plate 6 is horizontal, and its lower surface is slidably connected to the top of the sliding column 5. A sliding groove 7 is formed on the horizontal plate 6 along its length, and the length direction of the sliding groove 7 is consistent with the length direction of the horizontal plate 6. The horizontal plate 6 not only provides installation positions for the slider 8, screw 10, and drive assembly 11, but also, under the action of the drive assembly 11, can drive the slider 8 and punch 9 to move horizontally, thereby realizing the punching operation of the punch 9 at different positions on the steel structural components. The slider 8 is located in the sliding groove 7 of the horizontal plate 6, and its shape matches the sliding groove 7, sliding freely within the sliding groove 7 with a clearance fit. The bottom of the slider 8 is fixedly connected to the punch 9 by bolts, ensuring that the punch 9 can move synchronously during the movement of the slider 8. When the slider 8 slides horizontally within the sliding groove 7, it drives the punch 9 to be precisely positioned horizontally, ensuring that the punch 9 is aligned with the position on the steel structure that requires punching. The punch 9 is vertically fixed to the bottom of the slider 8, with its axis perpendicular to the bottom surface of the slider 8. The punch 9 is made of high-strength alloy steel and undergoes a special heat treatment process, giving it high hardness and good wear resistance. The head of the punch 9 is designed according to the shape and size requirements of the punching hole, commonly in the form of a sharp cone or cylinder, so that it can penetrate the steel structure smoothly during the punching process using its own impact force and hardness, thus completing the punching operation. The screw 10 is horizontally positioned within the sliding groove 7, with its axis aligned with the length direction of the sliding groove 7 and parallel to the length direction of the horizontal plate 6.One end of the screw 10 is connected to the drive assembly 11 via a coupling, while the other end is supported by a bearing on the other end of the sliding groove 7 to ensure smooth rotation of the screw 10. The screw 10 and the slider 8 are connected by a threaded connection. When the screw 10 rotates under the drive assembly 11, the slider 8 moves horizontally along the length of the sliding groove 7 using the threaded transmission principle, thereby adjusting the horizontal position of the punch 9 on the steel structure. The drive assembly 11 is bolted to the side of the horizontal plate 6, fitting snugly against the side of the horizontal plate 6. The drive assembly 11 can precisely control the rotation speed and angle of the screw 10, thereby achieving precise adjustment of the horizontal position of the slider 8 and the punch 9 to meet the requirements of different punching positions and spacings.

[0030] First, refer to Figure 2 In this embodiment, the punching assembly 4 further includes a support column 12. The support column 12 is bolted to the top of the base plate 2 and is vertical. A mounting plate 13 is bolted to the top of the support column 12. The mounting plate 13 is horizontal and fits against the top plane of the support column 12. The mounting plate 13 and the sliding column 5 are slidably connected. The sliding column 5 is perpendicular to the plane of the mounting plate 13 and can slide up and down within the corresponding pre-drilled hole or groove of the mounting plate 13. A first hydraulic cylinder 14 is bolted to the mounting plate 13. The cylinder body of cylinder 14 is connected to the mounting plate 13, and its output shaft is perpendicular to the plane of the mounting plate 13. The output shaft of the first hydraulic cylinder 14 is fixedly installed to the horizontal plate 6 by welding or bolt connection. Under the drive of the output shaft of the first hydraulic cylinder 14, the horizontal plate 6 can move along the extension and retraction direction of the output shaft. These newly added components work together with the original support frame 1, base plate 2, support rail 3 and punching assembly 4. For example, the first hydraulic cylinder 14 drives the horizontal plate 6 to move, which can provide auxiliary positioning, clamping or other related assistive actions for punching operation, thereby better completing the punching operation of steel structure.

[0031] Then, refer to Figure 3 In this embodiment, the drive assembly 11 includes a motor 15. The motor 15 is fixed to the side of the horizontal plate 6 by bolts. The sides of the motor 15 and the screw 10 are both connected by keys and have pulleys 16 installed. A first belt 17 is provided between the two pulleys 16. Through the transmission of the first belt 17, the power of the motor 15 is transmitted to the screw 10, causing the screw 10 to rotate.

[0032] Secondly, see Figure 5In this embodiment, a square groove 18 is also included. A square groove 18 is provided on the top of the slider 8. A threaded block 19 is slidably provided in the square groove 18 with a clearance fit. The threaded block 19 is connected to the screw 10 by a thread. When the screw 10 rotates, due to the threaded transmission, the threaded block 19 moves linearly in the square groove 18, thereby driving the slider 8 to move in the sliding groove 7 of the horizontal plate 6.

[0033] Again, see Figure 5 In this embodiment, a circular hole 20 is also included. Circular holes 20 are provided on both sides of the slider 8. Sliding columns 21 are fixedly provided on both sides of the threaded block 19 by welding. The sliding columns 21 and the circular holes 20 are slidably connected. Inside the circular hole 20, one end of the spring 22 is fixed to the bottom of the circular hole 20 by welding, and the other end is connected to the bottom of the sliding column 21 by welding. The spring 22 can provide buffering and reset function when the sliding column 21 slides.

[0034] In addition, see Figure 4 In this embodiment, a mounting bracket 23 is also included. The mounting bracket 23 is fixedly installed on the side of the base plate 2 by bolts. A second hydraulic cylinder 24 is fixedly installed on the mounting bracket 23 by bolts. A movable plate 25 is fixedly installed on the output shaft of the second hydraulic cylinder 24 by welding. The movable plate 25 is fixedly connected to the base plate 2 by bolts. The extension and retraction of the second hydraulic cylinder 24 can be transmitted to the base plate 2 through the movable plate 25, so that the base plate 2 produces a corresponding displacement.

[0035] Finally, see Figure 2 In this embodiment, a funnel 26 is also included. The bottom of the base plate 2 is fixed with a funnel 26 by bolts for collecting waste materials and other substances generated during the punching process.

[0036] Working principle:

[0037] When using this steel structure punching device, first observe the thickness of the steel structure component. Operate the first hydraulic cylinder 14, and the output shaft of the first hydraulic cylinder 14 extends and retracts, driving the horizontal plate 6 to move. The horizontal plate 6 is connected to the mounting plate 13, which in turn drives the mounting plate 13 to move up and down along the sliding column 5. The mounting plate 13 is connected to the horizontal plate 6, so that the horizontal plate 6 rises and falls synchronously on the sliding column 5. Adjust the vertical distance between the punch 9 and the steel structure component to ensure that the punch 9 can penetrate the steel structure component during punching. After determining the vertical position, start the motor 15 again. The motor 15 drives the screw 10 to rotate. The screw 10 is threadedly connected to the threaded block 19. The threaded block 19 slides in the square groove 18 at the top of the slider 8, driving the slider 8 to move horizontally in the sliding groove 7 of the horizontal plate 6. The movement aligns the punch 9 horizontally with the first punching position on the steel structure. During this process, the slide bar 21 slides within the circular holes 20 on both sides of the slider 8. The spring 22 within the circular holes 20 acts as a buffer and reset mechanism, ensuring smooth movement of the threaded block 19 and the slider 8. After the punch 9 is positioned, it is activated and moves rapidly downwards. With its high hardness and impact force, it penetrates the steel structure, completing the punching operation of the first hole. The punch 9 returns to its initial position, and the motor 15 is restarted. Following the horizontal positioning method described above, the punch 9 is adjusted to the next punching position. The horizontal positioning and punching operation steps are repeated according to the distribution of holes on the steel structure until all holes on the same horizontal plane are punched.
