Abstract

Изобретение относится к металлургическому машиностроению, а именно к способу получения порошковой проволоки с повышенной плотностью порошкового наполнителя. Задачей изобретения является повышение качества порошковой проволоки за счет увеличения плотности ее наполнителя, равномерности распределения его в поперечном и продольном направлении, а также повышение эксплуатационных характеристик готовой проволоки. Задача решается за счет того, что в способе получения порошковой проволоки с повышенной плотностью порошкового наполнителя, включающем непрерывное формирование из металлической ленты U-образного профиля с одновременным заполнением его порошковым наполнителем с разравниванием и предуплотнением, формирование замкнутого трубчатого профиля оболочки с фальцевым замком и редуцирование, согласно изобретению предуплотнение и разравнивание порошка ведется на устройстве вибрационного типа, а редуцирование замкнутого трубчатого профиля с фальцевым замком происходит в сдвоенной трехроликовой фильере, причем в первой группе роликов осуществляется образование трех глубоких гофров, обеспечивающих уменьшение поперечного сечения профиля до 20%, при этом один из гофров расположен в непосредственной близости к фальцевому замку, а во второй группе роликов, сдвинутых на 60° по оси формовки относительно первых, калибрование профиля с одновременным поджатием трех образованных гофров и возможностью уменьшения поперечного сечения профиля до 25%.The invention relates to metallurgical engineering, in particular to a method for producing powder wire with a high density of powder filler. The objective of the invention is to improve the quality of cored wire by increasing the density of its filler, the uniformity of its distribution in the transverse and longitudinal direction, as well as improving the performance characteristics of the finished wire. The task is solved due to the fact that in the method of obtaining powder wire with increased density of powder filler, including the continuous formation of a U-shaped profile from a metal tape with simultaneous filling it with a powder filler with leveling and precautionary, forming a closed tubular profile of a shell with a folded lock and reducing it According to the invention, the prevention and leveling of the powder is carried out on a vibration-type device, and the reduction of the closed tubular profile with f Altsevny lock occurs in a double three-roller die, and in the first group of rollers three deep corrugations are formed, reducing the cross section of the profile to 20%, while one of the corrugations is located in close proximity to the folded lock, and in the second group of rollers shifted by 60 ° along the forming axis relative to the first, profile calibration with simultaneous pressing of the three formed corrugations and the possibility of reducing the cross section of the profile up to 25%.
