Abstract
The invention discloses a weldless steel rim processing technology, for solving the problems that the existing weldless steel rim processing technology is easy to increase energy consumption and production cost due to the adoption of a heating process. The weldless steel rim processing technology comprises the steps of: cutting a seamless steel tube into a tubular blank with specified length, necking down and spinning one end of the tubular blank to form a transition section; flaring one end face of the transition section through spinning after the tubular blank is necked down to form a flange-shaped lockrand; turning around the blank, and flaring the other end of the tubular blank through spinning by taking the lockrand as a reference surface to form a flange-shaped large edge; finally punching the middle part of the semi-finished product, thus facilitating a tire air valve penetrating through the rim. And thereby the weldless steel rim processing technology has the advantages of being capable of reducing energy consumption and production cost.
