氮气缸弹压装置已经由北京农业工程大学和无锡模具厂研制成功，并于1987年12月29日在北京通过部级鉴定。它的研究成功，填补了我国弹压功能部件的空白，将有利于简化模具设计、缩短模具制造周期，提高冲压件质量，扩大压力机使用范围。目前氮气缸已投入小批制造，准备进一步推广应用。
Nitrogen cylinder pressure device has been successfully developed by Beijing Agricultural Engineering University and Wuxi Mold Factory, and passed ministerial appraisal in Beijing on December 29, 1987. Its successful research has filled in the blank of the pressure-activated functional components in our country, which will be helpful to simplify the mold design, shorten the mold manufacturing cycle, improve the quality of stamping parts and expand the use range of the press. At present nitrogen cylinder has been put into small batch manufacturing, ready for further promotion and application.
