Description
Таким образом, измен зазор в завиоимости от величины фактического удлинени заготовки , получим точные линейные и угловые размеры, определ ющие профиль детали.Thus, by changing the gap depending on the magnitude of the actual elongation of the workpiece, we obtain the exact linear and angular dimensions that define the profile of the part.
При обратном ротационном выдавливании цилиндрических деталей цеременного профил , сочетающего участки с переменной и посто нной толщиной стенки, данна зависимость учитывает любые отклонени зазора в пределах допуска на изготовление заготовки и детали, тем самым обеспечива точность липейпых размеров участков с посто нной толщиной стенки и точность угловых размеров участков с переменной толщиной стенки.When reverse rotational extrusion of cylindrical parts of a profile profile combining sections with variable and constant wall thickness, this relationship takes into account any deviations of the gap within the tolerance for the manufacture of the workpiece and parts, thereby ensuring the accuracy of Lipeyp sizes of sections with constant wall thickness and angular dimensions sections with variable wall thickness.
На фиг. 2 представлена схема обратного ротационного выдавливани деталей неременного профил по предлагаемому способу, при котором изменение зазора по установленной зависимости осуществл ют, например, за счет сообщени копиру движени в паиравлении перемещени металла со скоростью фактического удлинени деформируемого участка.FIG. Figure 2 shows a reverse rotational extrusion scheme for parts of a temporary profile according to the inventive method, in which the gap change according to the established relationship is effected, for example, by telling the copyer of the movement in the movement of the metal at the speed of the actual elongation of the deformable section.
Предлагаемый способ обеспечивает получение точного профил и при ведении процесса по схеме, когда в продольном направлении перемещаетс вращающа с оправка, а ролики имеют только радиальное перемещение.The proposed method provides for obtaining an exact profile when conducting the process according to the scheme, when the rotating mandrel moves in the longitudinal direction, and the rollers have only radial movement.
