Abstract
Способ концентричного углового прессования деталей типа стакана или чаши, включающий последовательные стадии: стадию выдавливания приводным пуансоном цилиндрической исходной заготовки из меньшей ступени сквозного ступенчатого отверстия контейнера с формированием промежуточной заготовки с утолщением у ее торца, ограниченного осесимметричным ручьем, образованным оппозитными поверхностями пары: торцом закрепленного на столе пресса дорна и переходной поверхностью между меньшей и большей ступенями упомянутого отверстия контейнера, стадию осадки промежуточной заготовки, а также стадию формирования кольцевой стенки детали выдавливанием осаженной промежуточной заготовки, отличающийся тем, что перед началом упомянутой стадии выдавливания исходной заготовки ограничивают исходные размеры упомянутого осесимметричного ручья в осевом направлении регулировкой положения контейнера относительно стола пресса, причем диаметральные размеры исходной заготовки и детали связаны следующим соотношением 0,87< d/(Dн-Dвн)<9,5, ! где d - диаметр заготовки перед штамповкой; ! Dн и Dвн - соответственно наружный и внутренний диаметральные размеры упомянутой детали. A method of concentric angular pressing of parts such as a glass or bowl, which includes successive stages: the stage of extrusion of a cylindrical initial billet from a smaller step of a through step opening of a container with a drive punch with the formation of an intermediate billet with a thickening at its end, limited by an axisymmetric handle formed by the opposite surfaces of the pair: the end fixed to the press table of the mandrel and the transition surface between the smaller and larger steps of said container opening, the step of upsetting the intermediate workpiece, as well as the stage of forming the annular wall of the part by extrusion of the deposited intermediate workpiece, characterized in that before starting the said stage of extruding the initial workpiece, the initial dimensions of the axisymmetric stream in the axial direction are limited by adjusting the position of the container relative to the press table, and the diametrical dimensions of the original workpiece and the details are connected by the following ratio 0.87 <d / (Dн-Dвн) <9.5,! where d is the diameter of the workpiece before stamping; ! Dн and Dвн - respectively, the outer and inner diametrical dimensions of the said part.
