The rim‑flattening and rolling machine is a specialized forming device designed to roll metal flat sheets into annular rim blanks. As the first core process in a steel wheel manufacturing line, it employs multi‑roller rolling technology to continuously bend flat sheet material into the open cylindrical workpiece required for the rim.
The automatic rim planing and rolling‑cutting unit is a critical integrated process on the steel wheel production line. It combines three key operations—planing, strengthening, and edge trimming—and, through hydraulic and automated control technologies, efficiently and reliably transforms the welded blank into a dimensionally accurate rim cylinder, laying a solid foundation for subsequent flaring and roll‑forming processes.
The rim planing and rolling unit is a specialized, integrated piece of equipment in the steel wheel rim manufacturing line. Positioned after the butt-welding process and before the rolling‑forming stage, it is used to treat the weld seams on the welded rim blanks. The equipment consists of three independent modules—the slag‑removal planer, the roller‑press, and the end‑cutting machine—and can be optionally equipped with a feeding mechanism to meet specific process requirements.
This machine tool is a CNC single‑column vertical lathe specially designed and developed for machining wheel rim, spoke, and hub components in the automotive wheel industry. It features a single‑spindle, single‑turret or dual‑turret configuration, with workpieces mounted vertically, making it ideal for high‑precision turning of disc‑shaped parts, short shafts, and complex curved‑surface components.
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.
