chill ring for producing bellows and bellows manufacturing method using it

摘要

The present invention provides a chilling (chill ring) with these chilling used to weld the diaphragm metal bellows relates to a method for producing a bellows for use . The present invention is separated into at least two parts , and the bellows diaphragm and the first surface which groove is formed to fit on the curved surface , and the second surface and the first surface is formed to be inclined so that the thickness becomes smaller toward the inside of claim provides for producing chilling bellows including a flat side to connect the outer peripheral end of the second side .
