一、概述焊接波纹管是金属波纹管的主要品种之一,它具有一些液压成形波纹管所不能比拟的优点。近二十年来,焊接波纹管引起人们的重视,在仪器仪表、电子工业和空间技术等方面已经得到了应用。焊接波纹管的制造方法与液压成形不同,它是采用精巧的焊接技术,把预先冲制的环状膜片沿其内外边缘交替焊接而制成。尽管这种工艺比较精细复杂,费用稍高。但是,由于材料加工变形小,尺寸精度容易控制,因此,制得的焊接波纹管具有灵敏度高、线性好、滞后小、位移大、弹性性能和有效面积偏差小等优点。此外,这种工艺方法还有可能加工塑性较
First, an overview Welding corrugated pipe is one of the main varieties of metal bellows, which has some advantages of hydraulically shaped bellows can not be compared. In the past two decades, welding bellows has attracted people’s attention and has been applied in instrumentation, electronics industry and space technology. Welding corrugated pipe manufacturing methods and hydroforming, it is the use of sophisticated welding technology, the pre-punched annular membrane along its inner and outer edges of the alternate welding. Although this process is more sophisticated, the cost is slightly higher. However, due to the small deformation of the material processing and easy control of the dimensional accuracy, the welded corrugated pipe has the advantages of high sensitivity, good linearity, small hysteresis, large displacement, small deviation in elastic performance and effective area. In addition, this process is also possible plasticity
