Изобретение отпоеитс к обработке металлов давлеиием, в частности к технологии изготовлени СИЛЬФОНОВ повышенной эластнчности .The invention can be applied to the processing of metals by pressure, in particular to the technology of manufacturing BELLOWS of increased elasticity.
По основному авт. св. № 479527 известен снособ изготовлени таких сильфонов, по которому последовательно формуют гофры путем раздачи кольцевого участка трубной заготовки и одновременного осуществлени рифлени на ранее отформованном гладком гофре.According to the main author. St. No. 479527 is well known for the manufacture of such bellows, according to which the corrugations are sequentially molded by distributing the annular section of the tubular billet and simultaneously making corrugation on a previously formed smooth corrugation.
Оформление рифленнй на гладком гофре производитс за счет двухосного раст жени , привод щего к зпачительному утонению материала заготовки и большой неравномерностп толщины стенки, что значительно снижает качество сильфона.The design of the grooves on a smooth corrugation is made by biaxial stretching, which leads to a pronounced thinning of the workpiece material and a large unevenness of the wall thickness, which significantly reduces the quality of the bellows.
Целью изобретени вл етс снижение утоиеии стенок сильфонов.The aim of the invention is to reduce the wall thickness of the bellows.
Указанна цель достигаетс тем, что при раздаче кольцевого участка трубной заготовки формуют кольцевые рифлени на стенке гофра, прилегающей к ранее отформованному гофру.This goal is achieved by the fact that when the ring portion of the billet is distributed, annular grooves are formed on the corrugation wall adjacent to the previously formed corrugation.
На фиг. I-3 иоказана последовательность формообразовани сильфона повьпиениой эластичности .FIG. I-3 demonstrates the sequence of formation of the bellows and the elasticity.
Суть сиособа заключаетс в следующем. Сначала формуют гофр 1 (см. фиг. 1), одна бокова поверхность которого со стороны не2The essence of the method is as follows. First, corrugation 1 is formed (see FIG. 1), one side surface of which is from the side 2
закренленного конца заготовки гладка , а друга -с кольцевыми рифлеии мн за счет раздачи кольцевого участка и осевого смещени свободной части трубчатой заготовки. Затем формуют кольцевые эквидистантно расположенные рнфлени на гладкой боковой поверхности гофра 1 и одновременно оформл ют следующий гофр 2 (см. рис. 2), с гладкой боковой поверхностью со стороны незакрепленного конца заготовки и другую боковую иоверхность с кольцевыми рифлени ми.the tapered end of the workpiece is smooth, and the other, with annular ribs, due to the distribution of the ring section and axial displacement of the free part of the tubular workpiece. Then, equidistant annular shapes are formed on the smooth side surface of the corrugation 1 and at the same time they form the next corrugation 2 (see Fig. 2), with a smooth side surface on the loose end of the workpiece and the other side and surface with ring grooves.
После этого иастунает этаи установивилегос режима последователь}юго формообразовани , когда в работе одновременно наход тс три гофра 1, 2, 3 (см. фиг. 3).After that, the runner and the south shaping mode of the liquefaction mode are in use, when three corrugations 1, 2, 3 are in operation at the same time (see Fig. 3).
Предложенный способ изготовленн снльфонов повышает качество и эксплуатационную надежность сильфонов за счет того, что умепьи1аетс утонение н разностенность гофра .The proposed method of fabrication of sflfonov improves the quality and operational reliability of the bellows due to the fact that umepie thinning n raznesennost corrugation.
