[0002] Steel structures are building structures made of steel materials connected by welding, bolts or rivets. They are widely used in factories, bridges, high-rise buildings and other fields. Cutting is a key step in steel structure processing, and its purpose includes size customization, component processing, installation adaptation and defect repair.

[0003] Patent CN221210050U discloses a steel structure plate cutting machine. It includes a frame, a cutting table and cutting device mounted on the frame, and a steel plate conveyor line. The steel plate conveyor line is located on one side of the cutting table, and the cutting device is located above the cutting table. A clamping device is provided on the cutting table. Using this patent, steel is placed on the steel plate conveyor line, and a cutting motor drives a cutting saw blade to cut the steel. However, this existing patent lacks a tail support function for the steel during cutting. During cutting, the unsupported portion will be suspended in the air, and cutting vibration will be transmitted to the unsupported area, causing the cut position to shift. Furthermore, stress concentration during cutting can lead to sudden sagging and breakage.

[0004] Therefore, there is a need for a steel structure cutting device that can support the cutting tail of steel of different sizes. Utility Model Content

Detailed Implementation

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0022] Example 1: A steel structure cutting device, see reference Figures 1-5 As shown, the device includes a support frame 1, a support plate 3, a rotating shaft 4, a mounting bracket 5, a torsion spring 6, a servo motor 7, a protective cover 8, and a cutting saw blade 10. The support plate 3 is welded to the top rear side of the support frame 1. A rotating shaft 4 is rotatably mounted on the support plate 3. The mounting bracket 5 is fixedly connected to the right end of the rotating shaft 4. A torsion spring 6 is fitted onto the rotating shaft 4. The two ends of the torsion spring 6 are connected to the support plate 3 and the mounting bracket 5, respectively. The servo motor 7 is bolted to the front right side of the mounting bracket 5. The cutting saw blade 10 is mounted on the output shaft of the servo motor 7. The mounting bracket 5 is fixedly connected to... The support frame 1 is equipped with a protective cover 8, and the cutting saw blade 10 rotates inside the protective cover 8. The support frame 1 has a receiving groove 9 located below the cutting saw blade 10. It also includes a guide rail 11, a sliding frame 12, a limiting plate 13, a fixed seat 14, and a lead screw 15. The guide rail 11 is symmetrically installed at the top of the support frame 1 by welding. The fixed seat 14 is fixedly connected to the top of the support frame 1. The lead screw 15 is rotatably installed on the fixed seat 14. The sliding frame 12 is threaded on the lead screw 15. The limiting plate 13 is fixedly connected to the left side of the sliding frame 12. The lead screw 15 rotates on the limiting plate 13.

[0023] See Figure 1 , Figure 2 and Figure 5 As shown, it also includes conveyor rollers 2, and seven conveyor rollers 2 are evenly spaced and rotated on the upper part of the support frame 1.

[0024] See Figure 3 and Figure 5As shown, it also includes a handle 27, which is fixedly connected to the protective cover 8.

[0025] When using this device, first, rotate the lead screw 15. The lead screw 15 drives the sliding frame 12 to move horizontally along the guide rail 11. The sliding frame 12 drives the limiting plate 13 to move outward, thus supporting the tail of steel structures of different lengths during cutting and preventing material shaking and falling off during the cutting process, ensuring the safety of the work site. Then, place the steel structure on the support frame 1. The steel structure extrusion conveyor roller 2 rotates, making it easy for the steel structure to be pushed into or pulled out of the cutting area. The end of the steel structure then abuts against the limiting plate 13. Then, start the servo motor 7. The output shaft of the servo motor 7 drives the cutting saw blade 10 to rotate at high speed. Use the handle 27 to drive the mounting frame 5 to swing up and down through the rotating shaft 4 to cut the steel structure. The torsion spring 6 provides the rebound force, so that the mounting frame 5 automatically resets after cutting. The protective cover 8 covers the cutting saw blade 10 to prevent debris from flying and to ensure operational safety. The receiving groove 9 collects cutting waste and prevents the saw blade from directly contacting the support frame 1. After cutting, turn off the servo motor 7 and then remove the cut steel structure.

[0026] Example 2: Based on Example 1, refer to Figure 5 As shown, it also includes a limiting seat 16, a mounting seat 18, a clamping seat 19, and a screw 20. The limiting seat 16 is fixedly connected to the support frame 1. The support frame 1 has a sliding groove 17, which is located to the right of the receiving groove 9. The mounting seat 18 is fixedly connected to the top left side of the support frame 1. The screw 20 is rotatably mounted on the mounting seat 18. The clamping seat 19 is fixedly connected to the end of the screw 20. The clamping seat 19 slides in the sliding groove 17. The clamping seat 19 and the limiting seat 16 are located on the same horizontal line.

[0027] After the steel structure is placed on the support frame 1 and adjusted to the corresponding position, the screw 20 is rotated. The screw 20 drives the clamping seat 19 to move along the slide groove 17, so that the clamping seat 19 cooperates with the limiting seat 16 to clamp the steel structure, thereby preventing the steel structure from shifting during cutting and ensuring cutting accuracy. After cutting, the screw 20 is reversed to drive the clamping seat 19 to reset and disengage from the steel structure. Finally, the steel structure can be removed.

[0028] See Figure 1 , Figure 2 and Figure 4 As shown, it also includes an L-shaped plate 21 and a scale 22. The scale 22 is fixedly connected to the rear side of the limiting plate 13. The L-shaped plate 21 is set on the upper rear side of the support frame 1 by welding. The scale 22 slides on the L-shaped plate 21.

[0029] When the limiting plate 13 moves, it drives the scale 22 to move together. The cutting size is read through the scale on the L-shaped plate 21 to achieve precise positioning and thus ensure cutting accuracy.

[0030] See Figure 1 , Figure 3 and Figure 5 As shown, it also includes a dust collection hood 23, a suction nozzle 24, an air suction pipe 25, and a connector 26. The dust collection hood 23 is fixedly connected to the protective cover 8. The air suction pipe 25 is connected to the dust collection hood 23. The end of the air suction pipe 25 is connected to the suction nozzle 24. The top of the air suction pipe 25 is provided with a connector 26, which is connected to an external air pump.

[0031] During cutting, the external air pump is connected through the suction pipe 25 and then started. The external air pump sucks dust from the dust collection hood 23 and the cutting area through the suction pipe 25 and the suction nozzle 24, thereby reducing dust pollution in the working environment and improving operational safety. After cutting is completed, the external air pump can be turned off.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
