Изобретение относитс к обработке металлов давлением, а именно к способам изготовлени гнутых профилей .. The invention relates to the processing of metals by pressure, in particular to methods for the production of curved profiles.
Известны способы изготовлени гнутых профилей, включающие приложение к торцам заготовки противоположно направленных усилий и выдавливание материала заготовки в направлеНИИ перпендикул рном действию усилий 1 и 2.There are known methods for making curved profiles, including applying oppositely directed efforts to the ends of the blank and extruding the blank material in the direction perpendicular to the force 1 and 2.
Недостатком таких способов вл етс невозможность получени профилей с переменным радиусом изгиба, The disadvantage of such methods is the impossibility of obtaining profiles with a variable bending radius,
Цель изобретени - изготовление профилей с переменным радиусом изгиба .The purpose of the invention is the manufacture of profiles with a variable bending radius.
Поставленна цель достигаетс тем, что выдавливание ведут с одновременным приложением к заготовке с различной скоростью двух дополнительных усилий, направленных перпендикул рно боковой поверхности заготовки по обе стороны от вьщавливаемого профил . Дополнительные усили могут прикладыватьс симметрично оси выда1Вливаемого профил на рассто нии 0,52 диаметра описанной вокруг профил окружности.This goal is achieved by the fact that the extrusion is carried out with the simultaneous application to the workpiece at different speeds of two additional efforts directed perpendicularly to the side surface of the workpiece on both sides of the drawn profile. Additional forces may be applied symmetrically to the axis of the extruded profile at a distance of 0.52 of the diameter of the circumference circumscribed profile.
На фиг. 1-3 показаны три этапа осуществлени предлагаемого способа изготовлени гнутых профилей: исходное положение, выдавливание участка гнутого профил радиусом изгиба Р и выдавливание второго участка гнутого профил радиусом Pj .FIG. 1 to 3 show three steps in the implementation of the proposed method for making curved profiles: the initial position, extruding a section of a curved profile with a bending radius P and extruding the second section of a curved profile with a radius Pj.
Способ осуществл етс путем приложени к торцам заготовки 1, помещенной в полость контейнера 2, пуан сонами 3 и 4 противоположно направленных усилий и дополнительных усилий пуансонами 5 и 6. Дополнительные усили прикладываютс к заготовке одновременно с основными перпендикул рно боковой поверхности заготовки симметрично по обе стороны от выдавливаемого профил на рассто нии 0,5-2 диаметра описанной вокруг профил окружности. Скорости перемещени пуансонов 5 и 6 различны, что обеспечивает изгиб профил на определенный радиус РН фиг.2 , Изги€ вьдавливаемого профил происходи в сторону пуансона ,6, перемещаквдегос с меньшей скоростью. После получени профил с радиусом изгиба Р заданной длины (фйг.2), скорости переу1ещени пуансонов 5 и 6 измен ют такThe method is carried out by applying to the ends of the workpiece 1, placed in the cavity of the container 2, Poins with sones 3 and 4, oppositely directed efforts and additional efforts by the punches 5 and 6. Additional forces are applied to the workpiece simultaneously with the main perpendicular to the side surface of the workpiece extruded profile at a distance of 0.5-2 diameter described circumference around the profile. The speeds of movement of the punches 5 and 6 are different, which ensures the bending of the profile for a certain radius of the PH of FIG. 2, the bend of the pressurized profile occurs in the direction of the punch, 6, moving at a lower speed. After obtaining a profile with a bend radius P of a given length (Fig.2), the transfer speeds of the punches 5 and 6 are changed as follows.
чтобы обеспечивать получение второго профил радиусом Р.to provide the second profile with radius R.
Способ обеспечивает получение профилей с заданным количеством изогнутых участков переменного радиуса из1иба.The method provides profiles with a specified number of curved sections of variable radius of ibib.
