Abstract
Изобретение относитс к трубопрокатному производству. Цель изобретени - повышение точности геометрических размеров труб путем снижени кривизны концевых консольных участков. Порцию металла заготовки подают в валки и обжимают на удерживаемой от осевого смещени оправке 3 ручьевыми валками 2 переменного профил с поворотом заготовки посредством оправки, промежуточного и переднего патрона 5. Выход щую трубу поддерживают на геометрической оси стана в месте расположени торца оправки до переднего патрона 5 на длине (1,5-2,0)M .*98M, где M - величина подачиThis invention relates to pipe production. The purpose of the invention is to improve the accuracy of the geometric dimensions of pipes by reducing the curvature of the end cantilever sections. A portion of the billet metal is fed to the rolls and crimped on a mandrel 3 held from axial displacement by means of alternating profile 2 rolls with rotation of the billet by means of a mandrel, intermediate and front chuck 5. The outgoing tube is supported on the geometric axis of the mill at the location of the mandrel end to the front chuck 5 on length (1.5-2.0) M. * 98M, where M is the feed rate
μ - коэффициент выт жки. Повышение точности труб обеспечиваетс поддержанием трубы правильной втулкой 6, периодически поворачиваемой синхронно с трубой вокруг нее и ее оси за счет жесткого скреплени этой втулки 6 через обойму с поворачивающими трубу элементами переднего патрона, при этом внутренний диаметр втулки больше диаметра трубы. 2 ил.μ is the stretching ratio. Improving the accuracy of the pipes is ensured by maintaining the pipe with the correct sleeve 6, periodically turned synchronously with the pipe around it and its axis due to the rigid bonding of this sleeve 6 through the sleeve with the pipe-turning elements of the front cartridge, while the internal diameter of the sleeve is larger than the pipe diameter. 2 Il.
