至今,成形波纹管的装置和方法有许多种。一种是使用一个能成形波纹的构件,例如使用一个橡皮圈或相类似的东西,但是使用这种方法在许多情况下会遇到困难,其困难是在于控制成形构件的运动,尤其是对于大尺寸来讲,在制造方面显得更为困难。液压法成形波纹管也是众所周知的,与装置和方法有关的是成形管坯的充满管坯内部的有压液体,因为环模或金属板件按预想的径向 To date, there are many types of devices and methods for forming bellows. One is to use a corrugating member, such as a rubber band or the like, but using this method can in many cases be difficult with the difficulty of controlling the movement of the forming member, especially for large Size, in terms of manufacturing is even more difficult. Hydraulic forming of bellows is also well-known and relates to devices and methods in that the forming tube is filled with pressurized liquid inside the tube because the ring die or sheet metal is pressed in the desired radial direction
