Description

Изобретение относитс к области сварки труб, а именно к формовочным клет м с открытым калибром, предназнченным дл фо1 1овки полосы, в цилиндрическую трубную заготовку.The invention relates to the field of pipe welding, in particular to open-caliber molding stands, designed to form a strip, into a cylindrical billet.
Изобретение наиболее эффективно может быть использовано/при проектировании новых и реконструкции существующих формовочных и ФОРМОВОЧНОсварочных станов, на которых в настощее врем при выформовке кромок по вл ютсй накаты и надавы, привод щие к ухудшению качества формовки и переводу газопроводных труб в пониженные сорта.. The invention can most effectively be used / when designing new and reconstructing existing molding and FORMING-MILLING MILLS, where at present, when forming the edges, rolling and pressing occur, leading to deterioration in the quality of molding and conversion of gas pipes to lower grades ..
Известна клеть стана дл формовки полуцилиндров из листов конечной длины, содержаща станину с двум парами боковых валков, установленных посредством обойм в корпусах, шарнирно закрепленных относительно станины и св занных механизмом регулирова- ни 1,The known stand of the mill for forming semi-cylinders from sheets of finite length, comprising a frame with two pairs of side rolls, installed by means of clips in cases hinged relative to the frame and connected by the adjustment mechanism 1,
Недостатком такой валковой кассеты вл етс то, что перемещение валков по горизонтали и вертикали осуществл етс за счет поворота корпуса с парой валков и радиальногЬ перемещени обойм относительно из разворота.The disadvantage of such a roll cassette is that the rolls are moved horizontally and vertically by rotating the casing with a pair of rolls and radially moving the clips relative to the turn.
При этом, после выставки по горизонтали и вертикали отсутствует возможность разворота обоим относительно трубной заготовки, что ухудшает качество формовки, приводит к надавам и накатам и повышает процент перевод газопроводных труб в пониженные сорта , . .At the same time, after the exhibition, horizontally and vertically there is no possibility of reversal to both with respect to the pipe billet, which degrades the quality of molding, leads to pressures and rebounds and increases the percentage of gas pipes transferred to lower grades,. .
Наиболее близким .техническим решением к изобретению вл етс клеть трубоформовочного стана, содержаща станину с ДВУ1ЛЯ корпусами, «в каждом из которьк установлена поворотна обойма с парой гибочных валкоВ, образующих калибр, нажимные механиз- . мы и опорные ролики 2.The closest technical solution to the invention is the stand of the pipe forming mill, containing a frame with TWO housings, "in each of which a rotary cage with a pair of bending rolls, forming a caliber, and pressure mechanisms are installed. we and support rollers 2.
