一、概述弹簧管是电液伺服阀中的关键零件,其加工质量直接影响电液伺服阀的技术指标和使用性能,因此,弹簧管的制造是电液伺服阀研制的关键环节之一。弹簧管是薄壁弹性零件,壁厚仅在0.055mm左右,不仅具有很高的几何精度和光洁度要求,还必须具有优良的弹性和足够的刚度。上述性能集中的反映在弹簧管的内孔、外径及R转接部位的加工质量。
First, an overview Spring tube is a key part of the electro-hydraulic servo valve, the processing quality of a direct impact on the electro-hydraulic servo valve technical indicators and the use of performance, therefore, the spring tube manufacturing is the electro-hydraulic servo valve developed one of the key areas. Spring tube is a thin-walled flexible parts, wall thickness of only 0.055mm or so, not only has high geometric precision and finish requirements, but also must have excellent flexibility and sufficient rigidity. The performance of the concentrated reflection of the spring tube bore, outer diameter and R adapter parts of the processing quality.
