| To solve problems of high springback, poor dimensional accuracy, low material utilization and low production efficiency in high-strength steel roll forming process and produce the high-precision long sliding rails with ultra-high strength steel to meet the market demand, technical analysis of typical sliding rail products with DP980 ultra-high strength steel were made from three aspects: cross-sectional shape, dimensional accuracy and punching requirements. Aiming at characteristics of product, the punching scheme was designed. The three-step quality control method was used to optimize the forming process and the roll die design. Finally, a variety of methods were adopted to test the product quality. Product testing after actual manufacturing showed that indicators of the long sliding rail met requirements of the drawings by optimizing the roller design and adjusting the field process; It successfully solved the problem on forming of high-strength steel. Roll forming technology has more advantages over other forming processes in the manufacture of ultra-high strength steel materials and larger products. |
