分析了某储油筒的结构特点 ,指出最关键的是胀形部分工艺方案的制定 ,根据其产量的要求 ,制定了精轧 胀形 焊接的制造工艺方案。计算了其中关键的胀形工艺参数 ,并根据计算结果设计出一套简单实用的胀形 压平台模具。该套模具特别适合于试制和小批量生产 The structural characteristics of an oil storage cylinder were analyzed. The most critical point was the formulation of the bulging part of the process scheme. According to the requirements of its output, a manufacturing process scheme of the bulge forming of the finish rolling was developed. The key parameters of bulging process are calculated, and a simple and practical bulge forming mold is designed according to the calculation results. This set of mold is especially suitable for trial production and small batch production
