波纹管广泛的用在各种自动控制仪表中作为弹性敏感元件。随着我国仪表工业的发展,对这种弹性元件的要求也越来越高。管坯加工是制造波纹管的关键工序,过去是采用多次变薄拉伸的工艺。每次拉伸都需专门的模具,并且拉伸后还要除油,退火,酸洗。所以工序多,生产率 Bellows is widely used in a variety of automatic control instruments as a flexible sensor. With the development of China’s instrumentation industry, the requirements for such flexible components are also getting higher and higher. Tube processing is the manufacture of corrugated pipe key processes, the past is the use of multiple thinning process. Each stretching requires a special mold, and after stretching but also degreasing, annealing, pickling. So many processes, productivity
