Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, specifically to a laser cutting tooling for bending pipes. Background Technology

[0002] Pipe bends are accessories for various equipment and devices. Different equipment will have different shapes and processing requirements for pipe bends. When the shape of the pipe bend changes greatly and laser processing is required to open holes in different positions, the positioning during laser cutting is difficult to unify due to the large changes in its spatial angle. This causes the hole to deviate easily during opening and cannot be centered on the pipe body, resulting in defects or scrap, which affects the processing and forming of the pipe bend.
