Description
УСТРОЙСТВО ДЛЯ ДЕФОРМИРОВАНИЯ ТОНКОСТЕННЫХ ТРУБDEVICE FOR DEFORMING THIN-WALL PIPES
1one
Изобретение относитс к области обработки металлов давлением, в частности к оборудованию дл производства гофрированных труб.This invention relates to the field of metal forming, in particular to equipment for the production of corrugated pipes.
Известно устройство дл деформировани тонкостенных труб, содержащее волоку, составленную из приводных роликов, и оправку переменного сечени .A device for deforming thin-walled tubes comprising a fiber composed of drive rollers and a mandrel of variable cross section is known.
Дл переформовки круглых гофрированных труб в пр моугольные предлагаемое устройство снабжено по меньшей мере двум волоками , установленными вдоль оправки, а ролики имеют форму шестерен с профилем зуба, соответствующим профилю гофра.To transform round corrugated pipes into rectangular ones, the proposed device is equipped with at least two filaments installed along the mandrel, and the rollers have the shape of gears with a tooth profile corresponding to the corrugation profile.
На фиг. 1 схематично изображено предлагаемое устройство; на фиг. 2 - разрез по А-Л на фиг. 1; на фиг. 3 - разрез но Б - Б а фиг. 1.FIG. 1 schematically shows the proposed device; in fig. 2 is a section along the AL in FIG. one; in fig. 3 - section B - B and FIG. one.
Устройство содержит оправку /, изготовленную , например, из фторопласта и имеющую переменное сечение, и волоки, составленные ,из приводных роликов 2-4, имеющихThe device contains a mandrel /, made, for example, from a fluoroplastic and having a variable cross-section, and dies, made up of drive rollers 2-4, having
форму шестерен с профилем зуба, соответствующим профилю гофра.the shape of gears with a tooth profile corresponding to the corrugation profile.
Заготовку в виде цилиндрической гофрированной трубы 5 надевают на цилиндрический конец оправки / и проталкивают до соприкосновени с роликами 2. Враща сь ролики 2, а по мере перемещени трубы и ролики 3 и 4 протаскивают заготовку по оправке, придава ее сечению пр моугольную форму.A billet in the form of a cylindrical corrugated tube 5 is put on the cylindrical end of the mandrel / and pushed until it touches the rollers 2. The rollers 2 rotate, and as the tube moves, and the rollers 3 and 4 pull the billet along the mandrel, giving it a rectangular shape.
Предмет изобретени Subject invention
Устройство дл деформировани тонкостенных труб, содержащее волоку, составленную из приводных роликов, и оправку переменного сечени , отличающеес тем, что, с целью обеспечени возможности переформовки круглых гофрированных труб в пр моугольные, оно снабжено по меньшей мере двум волоками, установленными вдоль оправки, а ролики имеют форму щестерен с профилем зуба, соответствующим профилю гофра.A device for deforming thin-walled pipes containing a fiber composed of drive rollers and a mandrel of variable cross section, characterized in that, in order to enable the reforming of round corrugated pipes to rectangular, it is provided with at least two willows installed along the mandrel, and the rollers have the shape of shchestren with a tooth profile corresponding to the corrugation profile.
