Abstract

Изобретение относитс  к обработке металлов давлением, в частности к производству труб и трубных изделий. Цель изобретени  - повышение качества спиральношовных труб за счет увеличени  точности сборки кромок под сварку. При работе устройства кромка свариваемой ленты 27 проходит через зазор между регулирующими роликами 16 и 17 без изменени  направлени  изгиба и направлени  кривизны ленты. При изменении серповидности полосы посредством рычага 20 измен ют положение роликов 16 и 17, обеспечива  оптимальный сварочный зазор между кромками. 3 ил.The invention relates to the processing of metals by pressure, in particular the production of pipes and tubular products. The purpose of the invention is to improve the quality of spiral-welded pipes by increasing the accuracy of the assembly of the edges for welding. When the device is operated, the edge of the tape 27 to be welded passes through the gap between the adjusting rollers 16 and 17 without changing the direction of bending and the direction of curvature of the tape. When changing the crescent of the strip by means of the lever 20, the position of the rollers 16 and 17 is changed, providing an optimal welding gap between the edges. 3 il.
