Description
Изобретение относитс к сварочной технике , 8 частности к подкладным кольцам дл сварки кольцевых швов, и может примен тьс дл сварки тонкостенных обечаек большого диаметра.The invention relates to a welding technique, 8 in particular to backing rings for welding ring seams, and can be used for welding thin-walled shells of large diameter.
Известно разжимное подкладное кольцо дл сборки и сварки цилиндрических изделий , содержащее гибкие секторы, попарно соединенные механизмами разжима flf.A known spacer backing ring for assembling and welding cylindrical articles, containing flexible sectors connected in pairs by unclamping mechanisms flf.
Однако при использовании известного подкладного кольца создаетс искривление круговой линии обечайки из-за возникающего в процессе разжима изгибающегч) момента.However, when using the known backing ring, a curvature of the circumferential line of the shell is created due to the bending moment that occurs during the unclamping process.
Цель изобретени - повышение качества сборки путем устранени искривлени круговой линии при разжиме.The purpose of the invention is to improve the quality of the assembly by eliminating the curvature of the circular line during unclamping.
Поставленна цель достигаетс тем, что гибкие секторы соединены механизмами разжима через один.The goal is achieved by the fact that the flexible sectors are connected by expansion mechanisms through one.
На чертеже показан общий вид предлагаемого изобретени .The drawing shows a general view of the present invention.
Разжимное подкладное кольцо состоит из гибких секторов и разжимных механизмов 2.The expansion ring consists of flexible sectors and expansion mechanisms 2.
Разжимные механизмы установлены отдельно между каждыми четными и каждыми нечетными гибкими секторами по всему подкладьшму кольцу.Expansion mechanisms are installed separately between each even and each odd flexible sectors around the entire lining ring.
Собранное таким образом кольцо вставл ют внутрь одной из свариваемых обечаек, совмеща центр формирующей канавки со свариваемой кромкой. Кольцо разжимают до по влени сил трени между обечайкой и секторами, достаточных дл удержани The ring thus assembled is inserted into one of the welded shells, aligning the center of the forming groove with the edge to be welded. The ring is opened until the occurrence of friction forces between the shell and the sectors sufficient to hold
кольца в обечайке.rings in the shell.
На кольцо надевают вторую свариваемую обечайку и производ т окончательный разжим.A second welded shell is put on the ring and the final unclamp is produced.
В процессе окончательного разжима наружные поверхности секторов плотно прилегают к внутремнкм поверхност м свариваемых обечаек.In the process of the final unclamping, the outer surfaces of the sectors fit snugly to the inside surfaces of the welded shells.
Предлагаемое выполнение разжимного подкладного кольца обеспечивает равномерное прилегание гибких секторов к поверхкости обечаек, что исключает искривление круговой линии обечайки. В результате существенно улучшаютс услови процесса сварки и повышаетс качество сварки.The proposed implementation of the expanding backing ring provides a uniform fit of the flexible sectors to the surface of the shells, which eliminates the curvature of the circular line of the shell. As a result, the welding process conditions are significantly improved and the welding quality is improved.
