[0002] Steel structure processing, with its high strength, light weight and high strength characteristics, as well as the advantages of efficient construction brought by prefabrication in the factory and rapid assembly on site, not only realizes the flexible adaptation to complex building designs and meets the needs of earthquake toughness, but also highly conforms to the concept of green buildings due to the recyclability of materials. Although attention should be paid to anti-corrosion maintenance, in general, steel structures have shown unparalleled advantages and extensive application value in the field of modern construction, especially high-rise buildings, large-span structures and special modeling projects, with their significant contributions in shortening construction periods, reducing labor costs and supporting sustainable development.

The problems with the above technologies are: One of the core difficulties currently faced by the steel structure manufacturing industry is the inefficiency of the cutting process and the lack of continuity of the operation.

[0026] The working principle of this utility model:

[0027] When in use, first, a transmission rod can be installed at one end of the right side of the box body 7, and a conveyor belt can be set up through the transmission rod. When steel materials need to be fed into the device, the worker only needs to place the steel materials on the surface of the operating table 5. Then, the motor 6 is started. In this process, the motor 6 not only drives the conveyor belt, but also drives the driven gear 105 to rotate through the driving gear 104. The screw 106 closely connected to the driven gear 105 will rotate on the inner wall of the box body 7 under the drive of the driven gear 105. The design of the screw 106 is very clever, and opposite screws are used at both ends. This design enables the screw 106 to simultaneously drive the two sliders 101 on its surface to move toward the steel when it rotates. When the sliders 101 move to the appropriate position, they are connected to the clamping plate 103 through the connecting rod 102. As the sliders 101 move, the clamping plate 103 gradually moves closer to the steel and finally clamps the steel. This clamping method is both firm and reliable and can effectively prevent the steel from moving or shaking during the cutting process. When the steel is clamped, the device enters the cutting stage. At this time, the operation of the mechanical arm 8 will move the laser cutting machine 3 to The laser cutting technology has the advantages of fast cutting speed and high precision, which can greatly improve the production efficiency. After the cutting is completed, the motor 6 is reversed, so that the slider 101 on the screw 106 drives the clamping plate 103 to move outward, thereby loosening the clamping of the steel. At this time, the support rod 207 connected to the screw 106 begins to play a role. The support rod 207 is connected to the screw 106 through a belt. When the screw 106 rotates, the support rod 207 will also rotate accordingly. The first cam 204 and the second cam 204 are installed on the support rod 207. Cam 206, they are respectively responsible for lifting and transporting the steel. First, the first cam 204 rotates and uses the roller 203 to make the upper end of the push rod 201 contact with the steel, thereby lifting one end of the steel to a certain angle. After lifting, the second cam 206 begins to play a role. It contacts the lower surface of the steel and drives the steel forward through the friction pad 205. In this way, the steel is smoothly transported to the conveyor belt surface on the right side of the box 7. During the whole process, the device realizes automatic transmission, clamping, cutting and subsequent transportation of steel through precise mechanical transmission and automatic control.
