Изобретение относитс к области производства труб из малопластичных металлов.This invention relates to the manufacture of pipes from low-ductile metals.
Известен способ получени гильз из малопластичных металлов путем прошивки на оправке сплошных нагретых заготовок наA known method for producing sleeves from low-plastic metals by flashing solid heated blanks on a mandrel.
косовалковом стане с низким коэффициентом выт жки LI 1 .;kosovalkovy mill with a low coefficient of stretching LI 1.;
Недостатком его вл етс низкое качество получаемых изделий,Its disadvantage is the low quality of the products,
Цель изобретени состоит в побышении качества изделий.The purpose of the invention is to appreciate the quality of the products.
Дл этого предлагаетс способ, по которому сплошную нагретую заготовку прошивают на косовалковом стане с низким коэффициентом выт жки, при этом в качестве сплошной заготовки используют биметаллическую заготовку с сердцев1шой из малопластичного , не склонного к активному окислению металла, а прошивку осуществл ют при обжатии перед носком оправки 1О-18% и с коэффициентом выт жки не более 2 с последующим извлечением гильзы из наруз ного сло .To this end, a method is proposed in which a continuous heated billet is stitched on a low-draw roll mill, while a bimetallic billet with a core of slightly plastic, not prone to active metal oxidation, is used as a solid billet, and the piercing is carried out during compression 1 O-18% and with a draw ratio of no more than 2, followed by removing the liner from the outer layer.
Способ осуществл ют следующим образом: путем прессовани изготавливают сплоThe method is carried out as follows:
ную биметаллическую заготовку с сердцевиной из малопластичного, не склонного к активному окислению металла. Нагретую заготовку прошивают на оправке на косова/ ковом стане с,обжатием перед носком оправки lQ-18% и с коэффициентом выт жки не более 2. В процессе прошивки по границе слоев осуществл етс кольцевое разрушение. После трошивки гильзу извлекают из наружного сло .bimetallic billet with a core of low-plastic, not prone to active oxidation of the metal. The heated billet is stitched on a mandrel on a kosovo / forging mill, with a Q-18% compression in front of the mandrel toe and with a draw ratio of not more than 2. Ringing is performed along the layer boundary during the flashing process. After stitching, the sleeve is removed from the outer layer.
Предложенный способ позвол ет получать качественные гильзы из малопластичных металлов .The proposed method allows to obtain high-quality sleeves from low-plastic metals.
