Description

Technical Field

[0001] This utility model relates to a welding fixture for front and rear crossbeams of textile machinery. Background Technology

[0002] Internal high-pressure forming (UHP) is a type of hydroforming technology. It involves using tubular material as a blank, applying ultra-high pressure fluid inside the tube, and axially feeding material to press the blank into a mold cavity to form the desired workpiece. UHP-formed components are lightweight, of high quality, and offer flexible product design and a simplified process. They also feature near-net-shape forming and green manufacturing characteristics. Through effective cross-sectional and wall thickness design, many textile machinery parts can be manufactured from standard tubing into complex, single-piece components using UHP.

[0003] The existing production method has at least the following disadvantages: When welding the front and rear crossbeams in the existing textile machinery crossbeams, separate welding fixtures are usually used for classified welding, which makes it impossible to achieve unified welding. Moreover, after welding on one side, the crossbeam needs to be removed from the welding fixture, flipped over and repositioned, which is quite inconvenient. Utility Model Content
