Description
СПОСОБ ПРОИЗВОДСТВА СВАРНБ1Х ДВУХШОВНЫХ ТРУБ БОЛЬШОГО ДИАМЕТРАMETHOD OF MANUFACTURE OF WELDB1X TWO-SECTION PIPES OF BIG DIAMETER
Способы производства сварных двухшовных труб бол1)ШОго диаметра из двух узких листсв, прсдварительио сваренных в карту, известны.Methods for the production of welded double-seam pipes bol1) SECTION of the diameter of two narrow sheets, which are welded into the map, are known.
Предлагаетс более экономичный способ иронзг.одства сварных двухшовных труб большого диаметра, иозвол юш,ий использовать оборудование, ириАген емое дл изготовлени одноик.шиых труб.A more economical method of ironing large-diameter welded double-seam pipes is proposed, which is allowed using equipment that is used to make single-sided pipes.
Прсдлагаемьи способ отличаетс от извесгиых тем, что формовку листов выполн ют в две стадии - путем предварительного и окончательною поессоваии .The prescription method differs from izmezhyh in that the forming of sheets is carried out in two stages - by preliminary and final poressovaya.
В результате первой стадии обработки получают заготовку с дном в форме полуцилиндра и кромками с пр мыми участками, а после второй, выполн емой с помош,ью пуансона, снабженного двум параллельпыми брусь ми с пазами по кра м, в которые заход т кромки предвар1ггельно отформованной заготовки, нолучают полуцилиндр правильной формы.As a result of the first stage of processing, a blank with a bottom in the shape of a half cylinder and edges with straight sections is obtained, and after the second, made with a second punch, equipped with two parallel bars with grooves along the edges, into which the edges of the preformed molding enter , get a half cylinder of the correct form.
Сварку иолуцилиндрических заготовок, движущихс с одинаковой скоростью, производ т иаложением первою иаружного илн внутреннего шва, при этом несвариваемые кромки удерживают от расхождени роликовой проводкой .The welding of semi-cylindrical workpieces moving at the same speed is performed by overlapping the inside and outside of the inner seam, while holding the non-weldable edges against divergence by roller wiring.
Второй сварной шов накладываетс в следуюп1;ем иепрерывном стане наружной сварки после кантовки заготовки на 180°.The second weld is superimposed in the following; 1, and an external welding continuous mill after turning the workpiece through 180 °.
Процесс 1;а.1оженп шва таков же, как при производстве одиошовной трубы.Process 1; a.1. The weld is the same as in the production of the same pipe.
