Description
(54) СПОСОБ КОВКИ СЛИТКОВ(54) METHOD OF FORGING INGOTS
1one
Изобретение относитс к области обраббтки металлов давлением, а именно к способам ковки слитков.The invention relates to the field of metal pressure processing, in particular, to forging ingots.
Известен способ ковки слитков в комбинированных с верхним плоским и нижним вырезным бойках, включающий прот жку слитка, проводимую равномерными последовательными обжати ми в три прохода с кантовкой между проходами 1.The known method of forging ingots in combined with the upper flat and lower cut-out strikers, including the ingot drawing, carried out by uniform successive cuts in three passes with the turning between the passes 1.
Известный способ не обеспечивает получени качественных поковок ввиду недостаточной проработки осевой зоны поковок.The known method does not provide high-quality forgings due to insufficient development of the axial zone of the forgings.
Цель изобретени - повышение качества поковок.The purpose of the invention is to improve the quality of forgings.
Дл достижени цели путем лучшей проработки ее осевой зоны, обжатие ведут верхним бойком с шириной рабочей поверхности в 2-2,5 раза меньшей диаметра слитка, со степенью деформации 20-25%, а кантовку производ т на угол 120°.To achieve the goal by better elaboration of its axial zone, compression is carried out by the upper striker with a working surface width 2-2.5 times smaller than the ingot diameter, with a degree of deformation of 20-25%, and turning over is carried out at an angle of 120 °.
При этом уменьшение поперечного сечени дефекта происходит как за счет его выт жки вдоль оси, так и за счет интенсивного перемещени больших объемов .металла в радиальном направлении, т. е. дефект закрываетс , постепенно ст гива сь в точку.In this case, the reduction of the defect cross section occurs both due to its stretching along the axis, and due to the intensive movement of large volumes of the metal in the radial direction, i.e. the defect closes, gradually shrinking to a point.
Параметры степени деформации 20-25°/о, ширины рабочей части бойка в 2-2,5 раза -меньще диаметра слитка и угла кантовки на 120° вл ютс оптимальными.The parameters of the degree of deformation of 20–25 ° / o, the width of the working part of the striker 2–2.5 times, the ingot diameter and angle of turning by 120 °, are optimal.
Предлагаемый способ по сн етс чертежом . Используют заготовку - слиток 1 круглого сечени , полученную литьем. Ковка такой заготовки производитс комбинированными бойками с нижним вырезным 2 (поз. а) и верхним плоским 3. Обжати производ т последовательно по всей длине заготовки при ее перемещении. В дальнейшем заготовку два раза поочередно кантуют на угол 120° и повтор ют обжатие заготовки (поз. б, в). При таком способе имеет место интенсивна проработка метал-, ла в осевой зоне заготовки, способствующа закрытию и забарке внутренних дефектов.The proposed method is illustrated in the drawing. A billet - ingot of 1 round section obtained by casting is used. The forging of such a workpiece is carried out by combined dies with the bottom cut-out 2 (pos. A) and the top flat 3. Pressing is performed successively along the entire length of the workpiece as it moves. Subsequently, the billet is alternately turned over two times at an angle of 120 ° and compression of the billet is repeated (pos. B, c). With this method, an intensive study of metal in the axial zone of the workpiece takes place, contributing to the closure and barring of internal defects.
