Description

Technical Field

[0001] The present invention relates to the technical field of steel structure processing, in particular to a turning device for processing building steel structures. Background Art

[0002] Turning equipment generally refers to machine tools used for turning processing, with lathes being the most common. Lathes achieve precise shape and size processing by rotating the workpiece and using cutting tools to remove material. Turning equipment is widely used in industries such as metal processing, machinery manufacturing, automobiles, and aviation. In the construction industry, some shaft-type building steel structures generally require turning processing, but some workpieces experience bending and deformation during the material forming stage, resulting in uneven processing in various areas during turning, which affects the final processing quality. Existing turning equipment generally completes processing by clamping the workpiece and then feeding the tool and rotating the workpiece. Its function is single, and curved workpieces need to be straightened, but repeated back and forth transportation will affect processing efficiency. Based on this, the present invention proposes a turning equipment with rich functions, which eliminates the need for reciprocating transportation of the workpiece and can be straightened before formal processing. The straightening path is consistent with the clamping path, thereby improving processing efficiency. Summary of the Invention
