Description

Technical Field

[0001] This application relates to the field of steel processing technology, specifically to a hydraulic device for a novel steel straightening machine. Background Technology

[0002] Steel is a material with a specific shape, size, and properties, made from steel ingots or billets through pressure processing. Most steel processing involves pressure processing, causing plastic deformation of the steel (billets, ingots, etc.). Steel is generally divided into four categories: profiles, plates, pipes, and metal products. Among them, steel pipes may deform and bend due to external forces during production or after a period of use, affecting their delivery or reuse.

[0003] In the existing technology, in order to straighten a steel pipe, the bent section of the steel pipe needs to be transported to the straightening area, and then a rotating device is used to rotate the bent section to bulge upwards. The bent section is then pressed down by a hydraulic device to straighten the steel pipe. The above straightening process not only requires manual operation, but also cannot ensure the straightening quality. Therefore, the above problems urgently need to be solved. Summary of the Invention

[0052] In this embodiment, the drive mechanism 200 is installed on the end face of the worktable 100, which ensures that the drive roller 210 has lifting and adjusting space, ensures that the output steel pipe does not form a height difference with the support table 110, and also allows the use of steel pipes of different diameters.

[0053] In this embodiment, a limiting ring is provided at one end of the support platform 110 near the drive mechanism 200. The limiting ring is detachably installed on the support platform 110 and its diameter matches the diameter of the steel pipe. The drive roller 210 is provided with a semi-circular docking groove along the circumference and the diameter of the docking groove matches the diameter of the steel pipe.
