Claims (3)

1. Способ изготовления одногофрового сильфона путем изготовления тонкостенной трубной заготовки, включающего последовательное чередование нескольких операций ротационного выдавливания и проведения термообработки для снятия внутренних напряжений с последующей установкой трубной заготовки в устройство для формирования гофра и формирование из трубной заготовки одногофрового сильфона, отличающийся тем, что тонкостенную трубную заготовку изготавливают с внутренним диаметром, близким внутреннему диаметру цилиндрической части сильфона, а формирование гофра сильфона производят на оправке с кольцевой канавкой, служащей для формирования и размещения гофра, путем создания наружного давления в зоне гофра при предварительно прижатых концах трубной заготовки к оправке с возможностью их скольжения между оправкой и прижимом.1. A method of manufacturing a single-sided bellows by manufacturing a thin-walled tubular billet, comprising sequentially alternating several operations of rotational extrusion and heat treatment to relieve internal stresses, followed by installing the tubular billet in the device for forming a corrugation and forming a single-walled bellows from the tubular blank, characterized in that the thin-walled tubular the workpiece is made with an inner diameter close to the inner diameter of the cylindrical part of the bellows on, and the formation of the bellows corrugation is carried out on a mandrel with an annular groove serving to form and place the corrugation by creating external pressure in the corrugation zone with the ends of the pipe billet pre-pressed against the mandrel with the possibility of their sliding between the mandrel and the clamp. 2. Способ по п.1, отличающийся тем, что формирование гофра сильфона производят в два приема, создавая наружное давление в зоне гофра предварительно и окончательно.2. The method according to claim 1, characterized in that the formation of the bellows corrugation is carried out in two steps, creating external pressure in the corrugation zone previously and finally. 3. Способ по пп.1 и 2, отличающийся тем, что формирование гофра сильфона производят на вращающейся оправке, а наружное давление создают локально при локально прижатых концах трубной заготовки.3. The method according to PP.1 and 2, characterized in that the formation of the bellows corrugation is carried out on a rotating mandrel, and the external pressure is created locally at the locally pressed ends of the tube stock.
