摘要
提出了一种以薄板拉伸出的圆筒为坯料进行精密缩径生产轿车后簧座的新工艺 ,即拉伸→缩口成形 ,与传统的旋压成形比较 ,可大大降低设备投资 ,提高生产效率和产品质量 ,降低制造成本。并对圆筒精密缩径进行了变形分析和理论解析 ,采用数值模拟和实验方法研究了缩径成形参数 ,优化了工艺设计。
A new technique, drawing→necking, for precisely foming the rear spring seat of a car with the cylinder drawn from metal sheet as the blank was proposed. Compared with the conventional revolving pressure forming method, this new technique could enormously reduce the investment in equipment, enhance the manufacturing efficiency and product quality. The deformation analysis and the theoretical resolution on the precision necking of the cylinder were made. The mecking parameters were studied by numerical simulation and experimental methods, and the technological design was optimized.
