Description
Изобретение относитс к облао Фи производства винтовнх фасонных профилей методом волочени .This invention relates to the production of screw shaped profiles by the method of drawing.
Известна волока дл волочени винтовых профилей с расположением элементов ее рабочего канала по винтовой линии и имекщей посто н г ную подачу по всей дзшне рабочей части волоки.A die is known for dragging screw sections with the location of the elements of its working channel along a helix and having a constant feed throughout the working part of the die.
Недостатком такой волоки вл етс то, что при волочении винтовых просгалей сложной конфигурации с глубокими пазами процесс деформации металла затрудн етс ,точность прот нутых изделий снижаетс , кроме того, происходит интенсивный износ волоки.The drawback of such a die is that when drawing screw projections of a complex configuration with deep grooves, the metal deformation process is difficult, the accuracy of the stretched products decreases, and moreover, intensive wear of the die occurs.
Целью изобретени вл етс улучшение условий деформации металла , увеличение стойкости инстру мента и повышение точности прот гиваемых изделий.The aim of the invention is to improve the deformation conditions of the metal, increase the tool life and increase the accuracy of the products being pulled.

В предтагаемой волоке винтообразные элементы рабочего канала выполнены с измен ющимс шагом -опирали по длине рабочего канала. Величина изменени шага зависит от среденего коэффициента выт жки металла в каждом рассматриваемом сече1ши.In the preload, the screw-shaped elements of the working channel are made with varying pitch of the helix along the length of the working channel. The magnitude of the pitch change depends on the average metal stretch ratio in each considered cross section.
Така форма канала волоки соответствует естественному течению металла при его деформации в рабочей зоне, что повышает стойкость инструмента и увеличивает точность в чистоту поверхностиThis shape of the die channel corresponds to the natural flow of the metal during its deformation in the working area, which increases tool life and increases accuracy in surface finish.
