The rim rolling machine is a specialized machining device used in the forming process of steel wheel rims. It is suitable for roll‑forming rim blanks that have undergone preceding operations such as edge rolling, butt welding, and flaring. Through multiple passes with the rolling die, the flat‑shaped rim blank is progressively shaped into a finished rim featuring a defined groove profile—such as a deep groove or a flat bottom.
The steel‑rim slag‑removal machine is a specialized machine tool designed to remove weld slag and burrs from automotive steel rims—the steel ring portion of the wheel—following welding.
The rim‑rolling machine for plate‑type engineering wheels is a specialized forming device that continuously bends and deforms flat steel sheets into wheel rims used in construction machinery, heavy‑duty trucks, and other vehicles. Serving as the “skeleton‑shaper” on the rim‑production line, its primary task is to transform a flat sheet into an almost perfect circle, thereby preparing it for subsequent welding operations.
A flash butt welder is a highly efficient and reliable resistance welding machine that operates on the principle of “resistance heating plus upset forging.” In rim manufacturing, it serves as the critical equipment for welding the ends of profiled sections into a continuous ring. With precise PLC‑based control of the entire welding process, it is the core apparatus for achieving high‑quality welds on high‑strength steel rims.
In 2012, it was recognized as "Jilin Science and Technology Enterprise" by Jilin Science and Technology Department ". In November 2013, it became the cooperative education base of Changchun Institute of Technology.
