Изобретение относитс  к производству труб.The invention relates to the manufacture of pipes.

Известен способ формовки труб.ной заготовки из полосы под сварку в трубоформовочном стане с горизонтальными и вертикальными валками, ирн котором среднюю часть исходной полосы формуют гор-изонталы1ыми валками , а боковые кромки - вертикальными.There is a method of forming pipes. A blank from a strip for welding in a pipe forming mill with horizontal and vertical rolls, irn of which the middle part of the initial strip is formed by hot-rolled rolls and the side edges are vertical.

С целью улучшени  качества формовки кромок трубной заготовки нредлагаетс  исходную нолосу формовать нижними бочкообразными валками при одновременном удерживании ее боковых кромок в нроцессе формовки верхними Цил1нндрк4сскил и валками.In order to improve the quality of forming the edges of the tubular billet, it is suggested that the initial nolos be molded with lower barrel rolls while simultaneously holding its side edges in the molding process with upper rolls and rolls.

На фиг. 1 изображеиа заготовка, иоиеречное сечение; на фиг. 2-4 - формующие клети .на различных этапах формовки.FIG. 1 image blank, and a cross section; in fig. 2-4 - forming stands. At various stages of forming.

Заготовка в виде полосы I проталкиваетс  в фор.,ие клети, где ее боковые кромкнThe workpiece in the form of a strip I is pushed into the form, stand of the stand, where its lateral edges

удер 1;11Баютс  на одной высоте относительно линии прокатки верхними цилиндрическими валками 2, расиоложенными по траектории формуемой боковой кромки заготовки, а нижние бочкообразные валки 3 изгибают ее изнутри в напразлеиии от центра.jerks 1; 11B are at the same height relative to the rolling line with upper cylindrical rollers 2 located along the path of the formable side edge of the workpiece, and the lower barrel-shaped rollers 3 bend it from the inside outwards from the center.

Предмет изобретени Subject invention

Снособ трубной заготовки из полосы под сварку в трубофорлшвочном стане с нн/кнпмн и 15ерхними валками, отличающийс  тем, что, с целью улучшени  качества формовки кромок трубной заготовки, исходную полосу формуют нижними бочкообразными валкамН при одновременном удерживаннч ее боковых кромок в процессе формовки верхними цилиндрическими валками.The method of tubular billet from a strip for welding in a pipe mill with nn / cnpmn and top rolls, characterized in that, in order to improve the quality of the shaping of the edges of the tubular billet, the initial strip is molded with lower barrel-shaped valkamN while simultaneously holding its side edges during the molding with upper cylindrical bars .
