Изобретение относитс к области сварки и может быть использовано при сварке тонкостенного трубопровода сложной формы в различных отрасл х машиностроени .The invention relates to the field of welding and can be used when welding a thin-walled pipeline of complex shape in various fields of mechanical engineering.
Известно формирующее устройство дл сварки кольцевых швов, содержащее два р да контактирующих между собой и выполненных в виде клиньев формирующих элементов, шарнирио св занных с механизмом разжима и образук цих сплошное подкладное кольцо 1J.A forming device for welding annular welds is known, which contains two rows of contacting and wedge-shaped elements that are connected to the unclamping mechanism and form a continuous backing ring 1J.
Недостатком данного устройства вл етс то, что оно обеспечивает качество формировани шва только дл одного диаметра труб и требует смены клиньев под каждый новый диаметр .The disadvantage of this device is that it provides the quality of the formation of a seam for only one pipe diameter and requires a wedge change for each new diameter.
Наиболее близким к изобретению вл етс устройство дл сборки под сварку кольцевых швов, содержащее корпус, на котором смонтирован упругий элемент с направл квдими фланцами и раздвижньми секци ми с прижимной поверхностью, выполненных в виде сегментных колодок с подпружиненными штыр ми 2 .Closest to the invention is a device for assembling, for welding, annular welds, comprising a housing on which an elastic element is mounted with guides of flanges and sliding sections with a clamping surface made in the form of segment blocks with spring-loaded pins 2.
Недостатком указанного устройства вл етс то, что устройство позвол ,ВТ собирать трубы с радиусом сегментных колодок, а зазоры между колодкаviK вызывают некачественную форму сварного шва,снижа прочность сварного соединени .The disadvantage of this device is that the device allows HT to assemble pipes with a radius of segment blocks, and the gaps between the viK block cause the weld to have poor quality, reducing the strength of the welded joint.
Цель изобретени - улучшение качества сварного соединени путем повыиени прочности сварного шва.The purpose of the invention is to improve the quality of the welded joint by increasing the strength of the weld.
Указанна цель достигаетс тем, что кажда раздвижна секци выполне0 на в виде тавра с дугообразным основанием , каждое ив которых в свою очередь установлено на упругом элементе внахлест,при этом на прижимной поверхности указанного тавра This goal is achieved by the fact that each sliding section is made in the form of a brand with an arcuate base, each of which, in turn, is mounted on the elastic element of the overlap, while on the pressure surface of the specified brand
5 выполнен паз и в нем размещена кольцева пружинна лента, а направл ющие фланцы выполнены в виде крышек с окнаида и смонтированы по кра м упругого элемента, причем полки 5, a groove is made and an annular spring band is placed therein, and the guide flanges are made in the form of a windowed window cover and mounted along the edges of the elastic element, the shelves
0 тавров размещены в упом нутых окнах.0 brands are located in the aforementioned windows.
На фиг. 1 изображено устройство, разрез на фиг. 2 - сечение А-А на фиг. 1.FIG. 1 shows the device, a section of FIG. 2 is a section A-A in FIG. one.
Устройство содержит корпус 1 с The device includes a housing 1 with
5 отверстием 2, соединенный с гибким шлангом 3. На корпусе 1 закреплен упругий элемент 4 с направл ющими фланцами 5 с помощью ст гивающих гаек 6. Направл ющие фланцы 5 выпол0 нены в виде крьнлек с окнами. На упру5 by a hole 2 connected to a flexible hose 3. On the case 1, an elastic element 4 is fixed with guide flanges 5 by means of tightening nuts 6. The guide flanges 5 are made in the form of a clutch with windows. On upr
