Abstract
Изобретение относитс k обработке металлов давлением на станках дл ротационной выт жки. Цель изобретени - повышение производительности за счет совмещени операций съема оболочки и обрезки ее упорного торца и повышение качества деталей за счет исключени гофро- образовани оболочки при съеме с оправки. Заготовку 2 цилиндром гидроприжима 4 прижимаю т к оправке 3 и давильным инструментом 1 производ т ротационную выт жку оболочки 8. После завершени процесса формообразовани оболочки 8 включают выталкиватель 7, который смещает оболочку 8 по оправке 3 на величину своего хода. Под действием пружины 9 оболочка 8 фиксируетс между опорным диском 10 выталкивател 7 и прижимом 11. В этом положении производ т обрезку упорного торца оболочки (дна). Дл окончательного сн ти детали с оправхи 3 винтом 6 гидроприжим 4 вместе с прижимом 11 отвод т в крайнее правое положение, а выталкиватель 7 возвращают в исходное положение. 2 ил. слThe invention relates to the pressure treatment of metals on rotary stretching machines. The purpose of the invention is to increase productivity by combining the removal of the casing and cutting its abutting end and improving the quality of parts by eliminating the corrugation of the casing during removal from the mandrel. The billet 2 is pressed by the cylinder of hydraulic clamp 4 to the mandrel 3 and the pressing tool 1 produces a rotary stretching of the shell 8. After the process of shaping the shell 8 is completed, an ejector 7 is turned on, which displaces the shell 8 along the mandrel 3 by its stroke. Under the action of the spring 9, the shell 8 is fixed between the supporting disk 10 of the ejector 7 and the clamp 11. In this position, the thrust end of the shell (bottom) is trimmed. For the final removal of the part from the rim 3, the screw 6, the hydraulic clamp 4 together with the clamp 11 is retracted to the extreme right position, and the ejector 7 is returned to its original position. 2 Il. cl
