Description
(54) ВОЛОКА(54) HAIR
обжимной и калибрующей зон св заны приведенным соотношением, обеспечивающим устранение волнистости на поверхности прот нутых труб.crimping and calibrating zones are connected by the above ratio, which ensures elimination of waviness on the surface of leaked pipes.
Пример. Волочению подвергают трубы из ст. 20; размеры заготовки 30 х 1,0; коэффициент выт жки t l,8 {степень деформации 0,44). Размеры профил канала волоки; диаметр зоны 32,0 мм; катающий диаметр калкбрующей зоны 17,0 мм; высота конуса обжимной зоны 25,0 мм; углы при вершине конусов обжимной и калибрующей зон, соответственно, 34 и 6°. Высота калибрующей зоны, найденна по приведенной формуле, 8,8 мм. На поверхности прот нутых труб отсутствуют дефекты в виде винтового следа инструмента обкатки; качество поверхности удовлетворительное.Example. The pipe is subjected to drawing from art. 20; dimensions of the workpiece 30 x 1.0; stretching ratio t l, 8 {degree of deformation 0.44). Dimensions of the die channel profile; zone diameter 32.0 mm; rolling diameter calming zone 17.0 mm; height of the cone crimping zone 25.0 mm; the angles at the apex of the cones of the crimping and calibrating zones, respectively, 34 and 6 °. The height of the calibrating zone, found using the above formula, is 8.8 mm. There are no defects in the form of the screw mark of the running-in tool on the surface of the extruded pipes; surface quality is satisfactory.
Фор.ила изобретени Forail of invention
Волока, рабочий канал которой включает обжимную и калибрующую зоны, выполненные в виде обращенных друг к другу меньшк ми основани ми конусов, отличающа с тем, что, с целью снижени усили волочени и повышени качества поверхности труб, получаемых путем волочени - обкатки через волоку , установленную под углом 3-5 к оси волочени , обжимна зона выполнена с углом конуса 30-50°, а калибрующа - с углом конуса 6-10°, при этом высоты этих зон св заны между собой соотношением:Voloka, the working channel of which includes crimping and calibrating zones, made in the form of cones facing each other with smaller bases, characterized in that, in order to reduce the dragging force and improve the surface quality of the pipes, obtained by dragging through the fiber installed at an angle of 3-5 to the axis of the draw, the crimping zone is made with a cone angle of 30-50 °, and the calibrating area is with a cone angle of 6-10 °, while the heights of these zones are interconnected by the relation:
Н H
