Thin wall cold roll forming process

The invention discloses a thin wall cold roll forming process which solves the problems that bending, scratching and low machining precision occur when a thin-walled steel plate with the thickness of 1.5-3 mm is made into a round tube with a large diameter in a cold roll forming mode. The thin wall cold roll forming process includes several steps of raw material slitting, unit feeding, unit forming, high-frequency welding, straightening and saw cutting. In the coiling procedure of the raw material slitting process, coiled parts are improved, and a separator process sleeve is additionally arranged on a separator shaft; unit feeding is completed for a steel belt jointly through devices of an uncoiler, a leveler, a roller way, a cutoff welding machine, a double-delivery machine, a lifting roller way, a forming machine and the like; straightening operation is finished through a sizing mill, and a straightener does not need to be arranged additionally. According to the cold roll forming process, the steel plate with the thickness of 1.5-3 mm is made into the round tube with the diameter of 120-140 mm, machining precision is achieved in the mode that the diameter tolerance is +/- 0.5 mm, the curvature is millesimal and the width allowance of raw materials is +/- 0.3 mm, and surface scratching and sink marks of cold forming sectional steel cannot be caused in the machining process.
