Description

Technical Field

[0001] This utility model relates to the field of steel structure processing technology, and in particular to a punching device for steel structure processing. Background Technology

[0002] In the process of steel structure processing, in order to achieve the connection and assembly of steel structures, holes are punched in the steel structure. By punching holes in various components, bolts, rivets and other connectors can be used to firmly connect them together, ensuring the overall stability and strength of the steel structure and meeting the usage requirements of different construction, machinery and other fields.

[0003] Existing punching equipment consists of a worktable, a punching mechanism, and a fixing device. The worktable is used to support the steel structural parts. The punching mechanism includes a punch, a drive device, and a transmission assembly. The fixing device uses clamps, pressure plates, etc., to fix the workpiece by bolts or mechanical clamping. Its working principle is that the operator first places the steel structural parts on the worktable and fixes them. Then, the operator starts the drive device. For example, the motor drives the transmission assembly, converting the rotational motion into the reciprocating linear motion of the punch. When the punch moves downward, it penetrates the steel structural parts with the punching force to complete the punching. At the same time, the fixing device ensures that the position of the workpiece is stable during the punching process.

[0004] While existing punching equipment can perform punching tasks well on steel structures, it still has limitations when punching square tube steel structures. After punching one side of the square tube, due to the tube's width, existing equipment cannot directly punch the bottom. It is necessary to first release the tube from its fixation, manually flip it over, and then re-fix it before continuing the punching work. This process is cumbersome and complex, consuming a lot of time and labor costs, thus affecting product production efficiency. Therefore, a punching equipment for steel structure processing is proposed to solve the above problems. Utility Model Content

[0036] 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.

[0037] Reference Figures 1-8 An embodiment of this utility model provides a punching device for steel structure processing, including a workbench 1, a punching machine 2 mounted on the top of the workbench 1, a support frame 3 fixedly connected to the top of the workbench 1, a fixing hand 4 rotatably connected to the left side of the support frame 3, a second support frame 5 fixedly connected to the top of the workbench 1, a fixing component provided on the right side of the second support frame 5, a rotating component provided inside the second support frame 5, a support component provided inside the workbench 1, and a mounting frame 20 fixedly connected to the top of the workbench 1, with a collecting component provided inside the mounting frame 20.

[0038] Specifically, the workbench 1 serves as the basic load-bearing component of the equipment, providing installation positions for other components. The punching machine 2 is installed on the top of the workbench 1 and is used for punching the steel structure. This is existing technology. Support frame 1 3 and support frame 2 5 are fixed on the top of the workbench 1, serving to support and connect other components. Fixing hand 1 4 is rotatably connected to the left side of support frame 1 3 and can work with fixing hand 2 11 to fix the steel structure.

[0039] Reference Figures 1-2 The fixed assembly includes a rotating frame 6, which is rotatably connected to the right side of the support frame 2 5. A bidirectional threaded rod 7 is rotatably connected inside the rotating frame 6. Two sliding blocks 8 are threadedly connected to the outer circumference of the bidirectional threaded rod 7. A connecting rod 9 is rotatably connected to the right side of each of the two sliding blocks 8. A fixing block 10 is rotatably connected to the right side of each of the two connecting rods 9. A fixing hand 2 11 is fixedly connected to the right side of each of the two fixing blocks 10. A limiting block 12 is fixedly connected inside the rotating frame 6. The limiting block 12 is located in the middle of the bidirectional threaded rod 7. A rotating hand 13 is fixedly connected to the front end of the bidirectional threaded rod 7.

[0040] Specifically, the rotating frame 6 is rotatably connected to the right side of the support frame 2 5, and the bidirectional threaded rod 7 is rotatably connected inside the rotating frame 6. The position of the fixed hand 2 11 can be adjusted by rotating the bidirectional threaded rod 7. The sliding block 8 is threadedly connected to the outer circumference of the bidirectional threaded rod 7 and slides on its outer circumference as the bidirectional threaded rod 7 rotates. The connecting rod 9 connects the sliding block 8 and the fixed block 10, converting the sliding of the sliding block 8 into the movement of the fixed block 10. The fixed block 10 is fixedly connected to the right side of the fixed hand 2 11, driving the fixed hand 2 11 to move, thereby realizing the clamping or loosening operation of the steel structure. The limiting block 12 is fixed inside the rotating frame 6 and located in the middle of the bidirectional threaded rod 7, restricting the axial movement of the bidirectional threaded rod 7. The rotating hand 1 13 is fixed at the front end of the bidirectional threaded rod 7, making it convenient for the operator to rotate the bidirectional threaded rod 7.

[0041] Reference Figures 2-3 The rotating assembly includes a rotating rod 14 and a worm gear 16. The rotating rod 14 is rotatably connected inside the support frame 5. The right side of the rotating rod 14 is fixedly connected to the left side of the rotating frame 6. A worm wheel 15 is fixedly connected to the outer periphery of the rotating rod 14. The worm gear 16 is rotatably connected inside the support frame 5. The worm wheel 15 and the worm gear 16 mesh with each other. A rotating handle 17 is fixedly connected to the front end of the worm gear 16.

[0042] Specifically, the rotating rod 14 connects the rotating frame 6 and the worm gear 15. When the worm gear 15 rotates, it drives the rotating rod 14 to rotate, thereby causing the rotating frame 6 to rotate. The worm gear 15 meshes with the worm 16, and the rotation of the worm 16 drives the worm gear 15 to rotate. The handle 17 is fixed to the front end of the worm 16, making it convenient for the operator to rotate the worm 16, thereby controlling the rotation of the rotating frame 6 and the steel structure fixed on it, realizing the flipping operation of the steel structure.

[0043] Reference Figure 1 and Figure 4 The support assembly includes a support block 18 and a telescopic cylinder 19. The support block 18 is slidably connected inside the worktable 1, and the telescopic cylinder 19 is fixedly connected inside the worktable 1. The top of the telescopic cylinder 19 is fixedly connected to the bottom of the support block 18.

[0044] Specifically, the support block 18 is slidably connected inside the workbench 1 and can move up and down inside the workbench 1. The telescopic cylinder 19 is fixed inside the workbench 1 and its top is fixedly connected to the bottom of the support block 18. When punching the steel structure, the telescopic cylinder 19 is activated, and the telescopic cylinder 19 extends to push the support block 18 up. The support block 18 provides support for the steel structure placed on the workbench 1.

[0045] Reference Figures 5-8 The collection assembly includes an absorption fan 21, a collection box 22, and a collection pipe 24. The absorption fan 21 is fixedly connected to the rear end of the mounting frame 20. The collection box 22 is installed inside the mounting frame 20. The collection pipe 24 is fixedly connected to the front end of the mounting frame 20. A filter screen 23 is fixedly connected to the rear end of the collection box 22. The filter screen 23 is located at the front end of the absorption fan 21. A handle 25 is fixedly connected to the top of the collection box 22. Two fixing frames 26 are fixedly connected to the top of the mounting frame 20. A spring 27 is fixedly connected inside each of the two fixing frames 26. A locking block 28 is fixedly connected to the front end of each of the two springs 27. The top of each locking block 28 is set as an inclined edge. A limiting plate 29 is fixedly connected to the rear end of each of the two locking blocks 28. The two limiting plates 29 are slidably connected inside the two fixing frames 26 respectively.

[0046] Specifically, the mounting bracket 20 is fixed to the top of the workbench 1, providing installation space and support for the collection components. The absorption fan 21 is fixedly connected to the rear end of the mounting bracket 20. After activation, it creates a negative pressure inside the mounting bracket 20, drawing debris generated from punching holes on the surface of the workbench 1 into the collection box 22 through the collection pipe 24. The collection box 22 is installed inside the mounting bracket 20 to collect debris. The filter screen 23 is fixedly connected to the rear end of the collection box 22, located at the front end of the absorption fan 21, preventing debris from entering the absorption fan 21 and serving a filtering and protection function. A handle is also included. 25 is fixed to the top of the collection box 22, making it convenient for operators to lift the collection box 22 for cleaning. The fixing frame 26 is fixedly connected to the top of the mounting frame 20, and a spring 27 is fixedly connected inside. The front end of the spring 27 is connected to the locking block 28. The top of the locking block 28 is set as an inclined edge, so that when the collection box 22 is installed, the collection box 22 squeezes the locking block 28, causing the locking block 28 to compress the spring 27 and move into the fixing frame 26. When the collection box 22 is installed in place, the spring 27 returns to its original position, pushing the locking block 28 to lock the collection box 22, thereby fixing the collection box 22.

[0047] Working principle: When a square tube needs to be fixed for punching, first place the square tube between the second fixing hand 11 and the first fixing hand 4. Then, rotate the first fixing hand 13 to drive the double-threaded rod 7 to rotate, thereby driving the two sliding blocks 8 to move in opposite directions. This, in turn, drives the fixing block 10 to move through the connecting rod 9, causing the fixing block 10 to move the second fixing hand 11 left and right. This completes the conversion of the rotation of the double-threaded rod 7 into the linear motion of the second fixing hand 11, thus fixing the extruded square tube between the second fixing hand 11 and the first fixing hand 4. Then, activate the telescopic cylinder 19 to move the support block 18 to the bottom of the square tube. To support it, after punching one side of the square tube, the telescopic cylinder 19 can be activated to retract the support block 18 to prevent it from obstructing the rotation of the square tube. Then, the second rotating handle 17 is turned to drive the worm gear 16 to rotate, thereby meshing with the worm wheel 15. This causes the worm wheel 15 to rotate, which in turn drives the rotating rod 14 to rotate, causing the rotating frame 6 fixed on its left side to rotate as well. This causes the square tube fixed between the second fixing handle 11 and the first fixing handle 4 to rotate as well, thus completing the flipping of the square tube. This allows the square tube to be flipped and punched without having to be removed, improving the efficiency of punching the square tube.

[0048] Punching generates a lot of debris. When it is necessary to clean the debris, the absorption fan 21 can be activated to create a negative pressure inside the mounting bracket 20. This allows the debris on the surface of the workbench 1 to be absorbed through the collection pipe 24 and collected into the collection box 22, thus reducing the time required to clean the debris. When it is necessary to deal with the debris inside the collection box 22, simply press the locking block 28 into the fixing bracket 26, and the collection box 22 can be taken out through the handle 25. The debris inside the collection box 22 can then be cleaned separately. When reinstalling the cleaned collection box 22, simply install it directly into the mounting bracket 20. During installation, because the top of the locking block 28 is beveled, it will be automatically squeezed into the fixing bracket 26. When the collection box 22 is fully installed, the spring 27 will release the tension and reset the locking block 28, thus completing the fixation of the collection box 22 and completing the installation.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
