Our factory produces steel-cored aluminum stranded cable, which requires large quantities of steel-wood cable drums. In the process of processing the cable reel (disk diameter d_1=1400mm), a large number of cable reels and foreign semi-finished products need to be welded and rounded. This semi-finished ring steel ring workpiece is bent by a bending machine. A different degree of rebound occurs in the bend or after bending into a ring. This rebound phenomenon causes the workpiece to be lost.
