[0002] A bending device for steel structures is a mechanical device used to change the angle of steel materials. It is mainly used in the processing of steel structures in fields such as construction and bridges.

[0003] Patent document CN221833081U discloses a bending device for steel structure production, including a base. Support frames are fixedly connected to the left and right sides of the top of the base, and a top seat is fixedly connected to the top of each support frame. A clamping structure is provided in the middle of both the base and the top seat. A heating structure is provided inside the base. The clamping structure includes a fixed seat, the bottom of which is fixedly connected to the base, and a lower clamping block is fixedly connected to the top of the fixed seat. The heating structure includes a heat-conducting column, the bottom of which is fixedly connected to the base, and an electric heating tube is sleeved on the outside of the heat-conducting column. This bending device for steel structure production features a clamping mechanism and a heating structure on the base of the bending structure. The clamping mechanism improves the stability of the bending device when bending the steel structure, reducing the deviation that occurs during bending. The heating structure increases the bending speed of the bending device, thereby enhancing the practicality of the bending device.

[0004] The device described above is not convenient for replacing the upper and lower mold bases, and can only bend steel of one specification. It has certain limitations in use and does not have the advantage of protection, causing the steel to break and splatter during bending, which reduces the practicality of the device. Therefore, we propose a bending device for steel structures to solve this problem. Utility Model Content
