Description

Technical Field

[0001] This utility model relates to the field of vehicle frame processing, and in particular to a bending device for vehicle frame tubing. Background Art

[0002] The production of electric vehicle frames generally begins with purchasing a batch of steel pipes, which are then bent into different degrees of curvature according to the requirements of different electric vehicle models, before proceeding to the next step of assembly, such as splicing and welding.

[0003] Currently, most pipe bending machines operate around a fixed axis. This single mode limits the bending to specific planes and angles. For example, some simple manual pipe bending machines, or those driven by cylinders, cannot perform complex multi-angle or multi-plane bending. Because they can only bend around a fixed axis, when bending at different planes or angles is required, the position of the pipe on the bending machine needs to be frequently adjusted. It may even be necessary to remove the pipe and reinstall it. Each angle change requires manual adjustment of the pipe position, which consumes a lot of time and significantly reduces processing efficiency. Utility Model Content
