Roll Forming Process of the Tubeless Wheel Rim of the Motorcycle

The dimensions precision and the radius reducing thickness of the tubeless wheel's rimare higher required,the quality of it lies on the rim's production facilities and the rationalizattion of the die design,and the crux of the rim roll forming die design is to control the radius reducing thickness as the dimensions precision is guaranteed.The dies designed based on the method this paper gives not only makes the rim manufactured with the dies having higher dimensions precision,less radius reducing thickness,but also has in common use on every type rim,dies designed,so it has larger practical significance.
