Effect of Manufacturing Condition on Forming a Screw-Threaded Stainless Fuel Filler Tube

Article Preview

A growing demand for lightweight products has been brought about by the rapid development of new automobiles in order to reduce fuel consumption. One of the keys to reduced fuel consumption is to utilize high-strength, light materials like stainless-steel that are difficult to form due to their strength. This paper discusses the development of pressing technology that forms a relatively high-strength stainless-steel tube with surface screw threads. Our new press-forming process was tested to obtain accurate screw threads on stainless-steel tubes. A 3-D digitizer was used to measure the accuracy of tubes manufactured by the proposed pressing method. The proposed press-forming method decreases tube thickness more effectively than conventional roll-forming technology. The maximum decrease in material thickness produced by conventional roll forming was 40%, but the maximum decrease in material thickness produced by our press-forming process was 20%. Stress and strain were clarified by using a finite-element simulation to expand the effectiveness of the new press-forming technology.
