Description
Изобретение касаетс прокатки труб на расширительном стане косой прокатки из прошитой заготовки.The invention relates to the rolling of pipes in an expansion mill for oblique rolling from a stitched billet.
Предлагаема оправка отличаетс от известных тем, что, с целью сначала расширить заготовку до диаметра немного меньшего требуемого и затем сгладить с одновременным расширением до окончательных размеров, она выполнена в виде двух направленных вершинами в одну сторону примыкающих друг к другу усеченных конусов разимых диаметров .The proposed mandrel differs from those known in that, in order to first expand the workpiece to a diameter slightly smaller than required and then smooth out while simultaneously expanding to final dimensions, it is designed as two directional vertices in one direction adjacent to each other truncated cones of acceptable diameters.
На чертеже изображена оправка в разрезе.The drawing shows the mandrel in the section.
Усеченный конус /, предназначенный дл расширени заготовки до диаметра Di, переходит во второй конус 2 с диаметром D, который оканчиваетс цилиндрической частью 3 и доводит диаметр трубы до окончательного размера.The truncated cone /, intended to expand the workpiece to a diameter Di, passes into a second cone 2 with a diameter D, which ends with a cylindrical part 3 and brings the diameter of the pipe to a final size.
Предмет изобретени Subject invention
Оправка дл нрокатки труб на расширительном стане косой прокатки из лрошитой заготовки, отличающа с тем, что она выполнена в виде двух направленных вершинами в одну сторону примыкающих друг к другу усеченных конусов, разных диаметров, с целью сначала расщирить заготовку до диаметра немного меньщего требуемого , а затем сгладить с одновременным расширением до окончательных размеров.The mandrel for the tube rolling at the expansion mill of the oblique rolling of a gritted billet, characterized in that it is made in the form of two directional vertices in one direction adjacent truncated cones of different diameters adjacent to each other, in order to first stretch the billet to a diameter slightly smaller than required, then smooth with simultaneous expansion to final sizes.
