叠片式波纹管与挤压、电铸成形的波纹管相比,有壁薄、伸缩比大(动程大),弹力小(调节稳定),总体尺寸小等优点。它成为研制调频连调管的关键之一。文中采用凹凸圆弧波纹形式,制成了外径15mm、内径5.5mm,壁厚0.08mm和外径10.8mm,内径4mm,壁厚0.05mm两种波纹管。还采用蝶形波纹形式制成了外径10.8mm,内径4 mm,壁厚0.05mm的波纹管。目前壁厚0.05mm、内径为3mm的内圆焊缝业已焊接成功。为进一步缩小波纹管尺寸准备了条件。小型波纹管研制比之于较大的波纹管来说,将遇到一些新问题,除壁薄和内外圆尺寸小所带来的困难外,因为用于电真空器件上,波纹管要随器件一起径受850～900℃钎焊温度和长时间去气温度(550℃ 6～20小时)烘烤、对波纹管材料提出了新的要求,本文对几项关键的工艺措施,小波纹管的各项性能指标,几种材料的性能试验情况等三个方面进行了介绍:
Laminated corrugated pipe and extrusion, electroformed corrugated compared to a thin wall, telescopic ratio (large stroke), elasticity (stability adjustment), the overall size of small advantages. It becomes one of the keys to the development of FM liaison. In this paper, corrugated circular corrugated form, made of an outer diameter of 15mm, an inner diameter of 5.5mm, wall thickness 0.08mm and outer diameter of 10.8mm, an inner diameter of 4mm, wall thickness of 0.05mm two bellows. Also made of butterfly corrugated form outer diameter 10.8mm, inner diameter 4mm, wall thickness 0.05mm bellows. The current inner wall thickness of 0.05mm, inner diameter of 3mm inner circle weld has been successfully welded. In order to further reduce the size of the bellows prepared. Small corrugated pipe development than the larger corrugated pipe, it will encounter some new problems, in addition to thin wall and the small size of the outer circle caused by the difficulties, as used in electric vacuum device, the bellows to be with the device Together with the temperature of 850 ~ 900 ℃ brazing temperature and long time degassing temperature (550 ℃ 6 ~ 20 hours) baking, the corrugated pipe material put forward new requirements, this paper on several key process measures, small bellows The performance indicators, the performance test of several materials and other aspects were introduced:
