弹簧管是压力表中的关键弹性传感元件，其加工质量的好坏对压力表产品的质量、合格率、精度、工作稳定性有着很大的影响。60年代起已有一些学者对弹簧管的性能、工作原理做过一些分析研究，但至今为止，对于小直径、薄壁弹簧管的成型工艺尚未见到比较详细的分析研究资料。随着 Spring tube pressure gauge is the key to the flexible sensing element, the quality of its processing of the pressure gauge product quality, pass rate, accuracy, work stability has a great impact. Since the 1960s, some scholars have done some analysis and research on the performance and working principle of the spring tube. Up to now, no detailed analysis and research data have been found on the forming process of the small diameter and thin spring tube. along with
