Abstract
Изобретение относитс к трубопрокатному производству и может быть использовано в станах холодной прокатки труб. Цель изобретени - повышение качества поверхности труб. В способе холодной прокатки труб осуществл ют деформацию заготовки валками 3 на оправке 4 и прав т на удлиненном конце 7 оправки искривлени передних концов труб правильной втулкой 6. Втулка расположена в переднем патроне 5. В зону правки подают охлаждающую жидкость через отверсти , выполненные в стенах правильной втулки. При этом исключаетс налипание металла на внутреннюю поверхность втулки и обеспечиваетс высокое качество поверхности труб. 2 ил.The invention relates to pipe production and can be used in cold rolling mills. The purpose of the invention is to improve the quality of the pipe surface. In the method of cold rolling of pipes, the workpiece is deformed by rolls 3 on mandrel 4 and is right on the elongated end 7 of mandrel by curving the front ends of the pipes with a regular sleeve 6. The sleeve is located in the front cartridge 5. A coolant is made in the straightening zone bushings. This prevents metal from sticking to the inner surface of the sleeve and ensures the high quality of the pipe surface. 2 Il.
