Abstract
1. Способ изготовления поковок типа днищ или крышек, включающий формирование донной и фланцевой частей поковки, при этом формирование донной части ведут осадкой исходной нагретой заготовки и ее открытой прошивкой пуансоном с образованием фланцевого утолщения, а фланцевую часть формируют после переустановки полуфабриката в другой штамп посредством радиального перемещения металла, отличающийся тем, что при формировании донной части осадку и прошивку исходной заготовки производят одновременно в первом штампе одним ходом одного пуансона, при этом обеспечивают формирование центрального выступа, после чего полученный полуфабрикат переставляют в другой штамп и ведут обратное выдавливание цилиндрической части полуфабриката с одновременным прямым выдавливанием центрального выступа, а формирование фланцевой части ведут после переустановки полуфабриката в третий штамп высадкой со свободным истечением металла в радиальном направлении относительно оси штампа.2. Способ по п.1, отличающийся тем, что перед операциями обратного и прямого выдавливания полуфабрикат подогревают до температуры 1200°С.1. A method of manufacturing forgings of the type of bottoms or caps, including the formation of the bottom and flange parts of the forgings, the formation of the bottom part being carried out by the draft of the initial heated billet and its open piercing with a punch to form a flange thickening, and the flange part is formed after reinstalling the semi-finished product into another die by means of a radial metal displacement, characterized in that during the formation of the bottom part, the sediment and the piercing of the initial billet are produced simultaneously in the first stamp with one stroke of one punch this ensures the formation of a central protrusion, after which the obtained semi-finished product is rearranged into another die and the cylindrical part of the semi-finished product is back pressed out while the central protrusion is directly extruded, and the flange part is formed after reinstalling the semi-finished product into the third die by disembarking with free metal flow in the radial direction relative to axis of the stamp. 2. The method according to claim 1, characterized in that before the operations of reverse and direct extrusion, the semi-finished product is heated to a temperature of 1200 ° C.
