Description
Пример З.В валках диаметром 5ОО мм медный порошок прокатывают в ленту шириной 600 мм с пористостью 25%j котора при выходе из валков имеет тол- ) шину 0,3 мм, увеличивающуюс постепенно на рассто нии 3-4 м до толщины 3 мм - и вйрнце прокатки вновь уменьшаютс до О,3 мм, Лента сворачиваетс в рулон диаметром 400 мм, высотой 600 мм, с отверстием 30 мм. Последн заготовка имеет более точные размеры по наружному диаметру и внутреннему отверстию, чем заготовка из пористой ленты посто нной толщины; она используетс дл изготовлени медной трубы гор чим прессованием с нагревом в за- щитной среде. Предлагаемый способ обеспечивает поттучение более экономичных заготовок по сравнению с известными, так как возможно изготовление заготовок из сплавов с малой пластичностью, а издели из такой заготовки имеют повышенное качество по стабильности физико-механических свойств. Предмет изобретени Способ изготовлени из порошка полых цилиндрических заготовок дл прессовани труб путем деформировани , о т л и ч а ющ и и с тем, что, с.целью повыщени производительности порошок прокатывают В ленту, которую затем сворачивают в рулон с продольным осевым отверстием.Example H. In rolls with a diameter of 5OO mm, copper powder is rolled into a 600 mm wide ribbon with a porosity of 25% j, which at the exit of the rolls has a thickness of 0.3 mm, increasing gradually over a distance of 3-4 m to a thickness of 3 mm and the rolling width is again reduced to O, 3 mm. The tape is rolled into a roll with a diameter of 400 mm, a height of 600 mm, with a hole of 30 mm. The latter billet has more accurate dimensions in outer diameter and inner bore than a billet of porous tape of constant thickness; It is used to make a copper tube by hot pressing with heating in a protective environment. The proposed method provides potting of more economical blanks compared to the known ones, since it is possible to manufacture blanks from alloys with low ductility, and products from such blanks have an increased quality in terms of the stability of their physical and mechanical properties. The subject of the invention is a method of making powder from hollow cylindrical blanks for pressing pipes by deforming, so that with the aim of increasing productivity, the powder is rolled into a ribbon, which is then rolled up into a roll with a longitudinal axial hole.
