Description

Technical Field

[0001] This utility model relates to the technical field of steel processing equipment, and in particular to a steel sawing device for steel structure engineering construction. Background Technology

[0002] As one of the main types of building structures, steel structure is a structural system constructed from steel materials. This structure mainly includes various components such as steel beams, steel columns, and steel trusses made from steel profiles and steel plates. In the construction of steel structures, in order to ensure that each component meets the design dimensions and shape requirements, sawing equipment has become an indispensable processing equipment. Its performance directly affects the manufacturing accuracy and construction efficiency of the steel structure, and plays a key role in the quality of the entire steel structure project.

[0003] Existing steel sawing equipment consists of a bed, saw blade, transmission mechanism, and clamping device. The saw blade is used to cut steel. The transmission mechanism transmits power through belts, gears, or hydraulics. The clamping device uses screws, nuts, or hydraulic cylinders to fix the steel and prevent it from shifting during cutting. In operation, the steel is first fixed, the equipment is started, and the transmission mechanism drives the saw blade to cut, thus completing the sawing.

[0004] Existing steel sawing equipment can cut steel well, but it still has limitations when cutting thinner steel. During the process of fixing the steel, existing equipment lacks a mechanism to effectively press down the edges. When sawing thinner steel, due to its thinness and relatively fragile structure, when the cutting force is concentrated on the middle part of the steel, the edges, lacking sufficient restraint, will exhibit obvious warping. This not only seriously affects the cutting accuracy but also leads to a large number of defective products. Therefore, a steel sawing device for steel structure engineering construction is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a steel sawing device for steel structure construction, which aims to improve the problem of the lack of an effective edge pressing mechanism for both sides of the steel in the existing technology, resulting in obvious edge warping.

The worm gear meshes with the worm wheel, causing the worm wheel to drive the threaded rod to rotate, thereby causing the sliding block to move within the support frame. The position of the sliding frame is adjusted so that the two sliding frames can respectively abut against both ends of the steel. Then, through the cooperation of the second handwheel, the second threaded rod, and the pressure plate, rotating the second handwheel causes the second threaded rod to rotate, driving the pressure plate to move within the sliding frame and abut against the surface of the steel, preventing the steel from warping during cutting, reducing defective products, and improving the quality of steel cutting.

The used water flows into the workbench and is filtered by the filter plate, reducing water waste. Pulling the handle pulls the locking block out of the slot through the pull rod, and the filter plate can be removed for cleaning or replacement using the handle. The installation is simple, the equipment is easy to maintain, and the equipment is guaranteed to operate continuously and stably. Attached Figure Description

A handle 18 is fixedly connected to the right side of the filter plate 17. A limiting block 24 is fixedly connected to the front end of each of the two pull rods 22. A handle 25 is fixedly connected to the front end of each of the two limiting blocks 24.

[0040] Specifically, the absorption water pipe 13 is fixed at the rear end of the workbench 1 to draw in cooling water from inside the workbench 1. The water pump 14 is connected to the absorption water pipe 13. After starting, it can draw in cooling water through the absorption water pipe 13 and output it through the output water pipe 15. One end of the output water pipe 15 is connected to the water pump 14, and the other end is connected to the cooling nozzle 16 to deliver cooling water to the cooling nozzle 16. The cooling nozzle 16 is fixed inside the cutting machine 26 and can spray cooling water on the cutting area to cool the cutting process, reduce material thermal deformation and cutting tool wear. A cutting groove is provided on the surface of the workbench 1 to provide a cutting position and allow cooling water to flow back into the workbench 1 through the cutting groove. The filter plate 17 is installed inside the workbench 1 to filter the cooling water flowing into the workbench 1 and remove impurities. The locking block 21 is slidably connected to... Inside the workbench 1, a slot 19 is provided at the front end of the filter plate 17 to fix the filter plate 17. A pull rod 22 is fixed to the front end of the locking block 21 for easy pulling of the locking block 21. A spring 23 is sleeved on the outer periphery of the pull rod 22. When the pull rod 22 is pulled to disengage the locking block 21 from the slot 19, the spring 23 is stretched. After the pull rod 22 is released, the elastic force of the spring 23 can reset the locking block 21 and re-engage it in the slot 19. A limiting groove 20 is provided inside the workbench 1. The pull rod 22 slides in the limiting groove 20, which guides and limits the movement of the pull rod 22. A handle 18 is fixed to the right side of the filter plate 17 for easy removal and installation of the filter plate 17. A limiting block 24 is fixed to the front end of the pull rod 22 to prevent the pull rod 22 from coming out of the limiting groove 20. A handle 25 is fixed to the front end of the limiting block 24 for easy pulling of the pull rod 22 by the operator.

[0041] Working principle: When steel needs to be cut, first place the steel on top of the workbench 1, then turn the first handwheel 7 to rotate the worm gear 6, which in turn rotates the worm wheel 5 through meshing, causing the threaded rod 4 to rotate. The sliding block 3 adjusts the position of the sliding frame 8 so that the two sliding frames 8 are respectively against the two ends of the steel. Then turn the second handwheel 11 to rotate the threaded rod 10, which drives the pressure plate 9 to move inside the sliding frame 8, so that the pressure plate 9 is against the surface of the steel, preventing the steel from warping due to force during cutting, thereby reducing defective products.

[0042] When cutting steel, the water pump 14 is started to draw cooling water from inside the workbench 1 through the absorption pipe 13, and then the cooling water is sent to the cooling nozzle 16 through the output pipe 15 to cool the cutting area. This helps to reduce material thermal deformation and cutting tool wear, improve cutting quality and tool life. The used water will flow back into the workbench 1 through the cutting groove and be filtered by the filter plate 17, thereby reducing water waste. The handle 25 can be pulled to pull the locking block 21 out of the slot 19 through the pull rod 22, so that the filter plate 17 is unrestrained. The slot 19 can then be pulled out through the handle 18 for cleaning or replacement. During installation, simply pull the handle 25 to let the locking block 21 enter the limiting groove 20 so as not to block the entry of the filter plate 17. Then, simply install it back in its original position, release the handle 25 to release the tension of the spring 23, and lock the locking block 21 back into the slot 19. The installation is then successful.
