Technical Field

[0001] The utility model relates to the technical field of automobile crossbeam processing, in particular to an elbow cutting positioning tooling for special-shaped pipe fittings of automobile crossbeams. Background Technique

[0002] An automobile anti-collision crossbeam is a device used to absorb collision energy when the vehicle is impacted. It can effectively absorb collision energy when the vehicle undergoes a low-speed collision and minimize the damage to the vehicle body longitudinal beam caused by the impact force. Currently, the automobile anti-collision crossbeam is formed by welding multiple parts, including multiple special-shaped pipe fittings and special-shaped elbows.

[0003] Currently, when cutting special-shaped pipe fittings and special-shaped elbows, it is necessary to position them at the corresponding processing positions to ensure their quick and stable support. However, the current method has a risk of movement when clamping and positioning the special-shaped elbows, which is likely to cause deviation during cutting and result in a decline in quality. Therefore, we propose an elbow cutting positioning tooling for special-shaped pipe fittings of automobile crossbeams to solve the above problems. Content of the Utility Model
