Description
Изобретение относитс к области производства труб.The invention relates to the field of pipe production.
Известен способ изготовлени пр .мошовных труб, при котором полосу формуют с изгибом трубпой заготовки выпуклостью в сторону дна.There is a known method of manufacturing molded pipe centers, in which the strip is formed with a bend of the preform pipe with a convexity towards the bottom.
Однако при таком способе формовки труб в зоне сварки из-за тепловых удлинений кромок и неточностей настройки, особенно нри производстве тонкостенных труб, часто возникают гофры, ухудшающие качество сварки и привод щие к повыщенному браку по превыщени м кромок.However, with this method of forming pipes in the weld zone, due to thermal lengthening of edges and inaccuracies of adjustment, especially when producing thin-walled pipes, corrugations often occur, which deteriorate the quality of welding and lead to increased rejects due to excess edges.
Целью изобретени вл етс улучшение качества труб и уменьшение энергозатрат.The aim of the invention is to improve the quality of pipes and reduce energy consumption.

Дл этого предложен способ, по которому изогнутую заготовку в зоне закрытых клетей формовочного стана и сварочного узла выпр мл ют и изгибают выпуклостью в сторону кромок.To this end, a method has been proposed in which a curved billet in the closed cage zone of the forming mill and the welding unit is straightened and bent with a bulge in the direction of the edges.
На чертеже показана схема формовки и сварки полосы по предлагаемому способу.The drawing shows a diagram of the molding and welding of the strip according to the proposed method.
Полосу / формуют путем непрерывного поперечного изгиба в трубную заготовку 2, которую в начальной стадии формовки изгибают в продольной плоскости выпуклостью в сторону дна 3, а в конечной стадии формовки и в зоне свпрочного узла ее выир мл ют и изгибают выпуклостью в сторону кромок 4.The strip / is molded by continuous transverse bending into pipe billet 2, which in the initial stage of molding is bent in the longitudinal plane with convexity towards the bottom 3, and in the final stage of forming and in the area of the solid unit, it is extruded and bent towards the edges 4.
Иредмет изобретени Iredmet invention
Снособ изготовлени сварных пр мошовных труб, включаю1ций формовку нолосы с изгибом трубной заготовки выпуклостью в сторону дна и сварку, отличающийс тем, что, с пелью улучшеин качества труб и уменьшени энергозатрат, изогнутую заготовку в зоне закрытых клетей формовочного стана и сварочиого узла выпр мл ют и изгибают выпуклостью в сторону кромок.A method for manufacturing welded straight seam pipes, including forming a nolosa with bending of a tubular billet with a convexity towards the bottom and welding, characterized in that, with a better quality of pipes and a reduction in energy costs, the bent billet in the zone of closed stands of the molding mill and the welding unit will be drawn and bend bulge in the direction of the edges.
