Description

Technical Field

[0001] The utility model relates to the technical field of straightening machines for scaffolding, and particularly relates to a steel positioning device. Background Technique

[0002] The straightening machine for scaffolding is a maintenance machine for the steel pipes of the building fastener steel pipe scaffolding. It is mainly used for straightening and repairing the bent and deformed scaffolding steel pipes and other pipes in building construction. When straightening the steel pipes, it is necessary to position them to ensure the straightness of the steel pipes.

[0003] For example, a steel positioning device for a straightening machine for scaffolding disclosed in Chinese Patent Publication No. (CN217831338U) records: "In the present utility model, the distance between the moving seat and the straightening machine for scaffolding can be adjusted through the sliding cooperation of the sliding rod and the sliding seat. The scaffolding steel pipe is placed between the arc-shaped bottom plate and the clamping member. The adjusting screw can drive the adjusting plate and the clamping member to clamp and position the scaffolding steel pipe. The arc-shaped bottom plate supports the scaffolding steel pipe, thereby ensuring the stability of the scaffolding steel pipe. The clamping member can limit the scaffolding steel pipe at the position corresponding to the feeding port. Compared with the above prior art, this scheme can position and provide a certain support for the longer steel pipe, which is convenient for ensuring the stability of the straightening of the scaffolding steel pipe", and also records: "When the length of the steel pipe is relatively long, its end enters from the feeding port, and the weight of the unentered part is relatively large, which will cause the part of the steel pipe outside the straightening machine to deflect downward, making it difficult to position and stabilize the steel pipe, affecting the entry and processing accuracy of the steel pipe, and even causing a jamming situation. Therefore, it is necessary to design a steel positioning device for a straightening machine for scaffolding to position the steel pipe" technical problem.

[0004] To sum up, the device also has the following technical problems: When the device is used, the steel is deformed by mechanical extrusion stress, so that the straightening of the steel can be completed. However, if the steel pipe is directly straightened by applying pressure after the steel is deformed, it will cause the secondary bending of the bending point of the steel pipe, which will reduce the overall compressive resistance of the steel pipe. Therefore, it is necessary to propose a steel positioning device to provide a new technical solution to solve the technical problems mentioned in the above patent. Summary of the Utility Model
