Изобретение относитс к обработке металлов давлением и может быть использовано дл получени трубчатых изделий с двойными стенками, например роликов ленточных конвейеров безвкладьшной конструкции.The invention relates to the processing of metals by pressure and can be used to produce tubular products with double walls, such as rollers of belt conveyors of an idleless design.
Известен способ изготовлени трубчатой заготовки выворотом в матрице с направл ющим радиусом с нагревом детали и матрицы l .A known method of manufacturing a tubular billet by inversion in a matrix with a guide radius with heating of the part and the matrix l.
Способ имеет недостатки, заключающиес в том, что кривизна наружной поверхности внеконтактного очага деформации больше заданной кр звизны рабочей поверхности матрицы.The method has the disadvantages that the curvature of the outer surface of the non-contact deformation zone is greater than the specified cr of the working surface of the matrix.
Цель изобретени - расширение технологических возможностей процесса за c)jeT уменьшени кривизны детали в зоне внеконтактного очага деформации.The purpose of the invention is to expand the technological capabilities of the process for c) jeT reducing the curvature of the part in the zone of non-contact deformation zone.
Поставленна цель достигаетс тем, что при изготовлении трубчатой заготовки выворотом .нагревают трубчатую заготовку только в. зоне внеконтактного очага деформации, при этом уровень температуры металла заготовки по длине образующей внеконтактного очага деформации регулируют пр мо пропорционально степени деформации.This goal is achieved by the fact that in the manufacture of a tubular billet by inversion, the tubular billet is heated only. zone of non-contact deformation zone, while the temperature level of the metal billet along the length of the generators of non-contact deformation zone regulate directly proportional to the degree of strain.
На фиг. 1 показана схема формообразовани внутреннего выворота; наFIG. 1 shows a pattern for shaping internal inversion; on
фиг. 2 - схема формообразовани наружного вывороЛга.FIG. 2 is a diagram of the shaping of the outer exponent.
Инструмент дл осуществлени данного способа содержит матрицу 1 и индукционный нагреватель в виде, одновиткового индуктора 2, размещенного в магнитопроводе 3.The tool for carrying out this method comprises a matrix 1 and an induction heater in the form of a single turn inductor 2 located in the magnetic core 3.
Пример. Стальную трубчатую Example. Steel tubular
0 заготовку D X S 152 х 4,5 деформируют в матрице с криволинейной образующей посто нной кривизны К ,0, the workpiece D X S 152 x 4.5 is deformed in a matrix with a curvilinear generatrix of constant curvature K,
где радиус матрицы, R 26 мм. Деформаци трубчатой заготовки в зонеwhere is the radius of the matrix, R 26 mm. Deformation of the tubular billet in the zone
5 контактного очага деформации осуществл етс нахолодно на гидропрессе с технологическим усилием .110 т. Скорость осевого перемещени штока гидропресса в процессе формообразовани 5 contact deformation zone is carried out coldly on the hydraulic press with a technological force of .110 tons. The speed of the axial movement of the hydraulic press rod during the shaping process
0 равна 5 мм/с. Рабочую поверхность матрицы перед деформацией смазывают двусернистым молибденом с минеральным маслом. После того, как край трубчатой заготовки выходит в0 is 5 mm / s. Before the deformation, the working surface of the matrix is smeared with two-molybdenum with mineral oil. After the edge of the tubular billet goes into
