Beschreibung
Zusammenfassung:	The invention belongs to a thermal forming technique and relates to the improvement of a manufacture method for a high-temperature alloy sine bellows spring, which comprises the following forming steps of punching and cutting spring blank, mechanically deforming the spring blank, and carrying out solid solution and aging thermal treatment to the spring blank together with a thermal treating mould. The invention solves the problem that the shape of the bellows spring can not be kept after the bellows spring is machined and formed, ensures the design requirements of physical dimensions and wave shapes of the bellows spring, and improves the machining qualified rate of the bellows spring.
