1results about How to "Reduce weld cracking" patented technology

This invention discloses a manufacturing equipment and method for hot roughing universal joints used in metallurgical steel rolling. The equipment includes a worktable with four support legs at its bottom and a central control system at its top. It also includes a speed-changing support mechanism mounted on the top of the worktable, with two fixing mechanisms on the mechanism. The two fixing mechanisms respectively fix the universal joint and a flange. This supports the universal joint and the flange, enabling synchronous rotation and position adjustment, providing stable support for subsequent welding, straightening, and other processes. This device significantly improves welding quality by refining grains and dispersing impurities through multi-field coupling; avoiding surface damage through non-contact creep straightening; achieving micron-level straightening through ultrasonic rolling; forming a deep residual compressive stress layer to improve fatigue resistance; reducing human error through automated closed-loop control; adapting to various workpiece specifications; and significantly improving efficiency and reducing costs through integrated processing.
