Description

Technical Field

[0001] The utility model relates to a welding jig for a crossbeam square tube of a textile machine. Background Technique

[0002] Internal high-pressure forming is a kind of hydroforming technology. It uses a pipe as a blank and forms the pipe blank into a required workpiece by applying ultra-high-pressure liquid inside the pipe and axial feeding and feeding to press the pipe blank into the mold cavity. The components formed by internal high-pressure forming are light in weight, good in product quality, flexible in product design, simple in process, and have characteristics such as near-net forming and green manufacturing.
