Изобретение относитс к обработке металлов давлением, а именно к способам осадки заготовок..The invention relates to the processing of metals by pressure, and in particular to methods for precipitating blanks.

Известен способ одновременной осадки заготовок, включающий укладку двух одинаковьлх цилиндрических заготовок параллельно одна другой на плиту и их совместное деформирование усилием, перпендикул рным продольным ос м заготовок 1.There is a known method of simultaneous precipitation of blanks, which includes laying two identical cylindrical blanks parallel to each other on a slab and their joint deformation with a force perpendicular to the longitudinal axis of the blanks 1.

Недостаток известного способа ограниченность номенклатуры изготавливаемых изделий.The disadvantage of this method is the limited range of manufactured products.

Цель изобретени - расширение номенклатуры изготавливаемых изделийThe purpose of the invention is to expand the range of manufactured products.

Поставленна цель достигаетс тем, что в способе одновременной осадки заготовок, включающем усгщку двух одинаковых цилиндрических заготовок параллельно одна другой ..на плиту и их совместное деформированиеусилием , перпендикул рным ос м заготовок, заготовки укладывают с зазором между их боковыми поверхност ми , не превышающими двух диаметров заготовки, а при совместном деформировании усилие прилагают к участкгии заготовок длиной не менее 30% их длины.The goal is achieved by the fact that in the method of simultaneous precipitation of workpieces, including cutting two identical cylindrical workpieces parallel to one another. blanks, and when jointly deformed, force is applied to the section of blanks with a length of at least 30% of their length.

На фиг.1 показаны две заготовки, уложенные на нижнюю плиту (плоскую) образунадими и контактирующими боковыми поверхност ми; на фиг.2 - блок поковок, полученных после одновременной осадки по всей длине; на фиг.З - отдельна поковка после разделени блока; на фиг.4 - штамповка , дл изготовлени которой можно использовать полученную поковку; на фиг.5 - две заготовки, уложенные друг от друга на рассто нии двух диаметров и их форма после осадки по всей длине; на фиг.6 - две заготовки, часть длины которых осажена , при этом осаженный участок расположен в средней части заготовок; на фиг.7 - две заготовки, осаженный участок у которых расположен с од20 ной стороны.In Fig. 1, two blanks are shown laid on the lower plate (flat) formed and contacting side surfaces; figure 2 - block forgings obtained after simultaneous precipitation along the entire length; in FIG. 3, a separate forging after block separation; Fig. 4 shows a stamping, for the manufacture of which the resulting forging can be used; Fig. 5 shows two blanks stacked apart from each other at a distance of two diameters and their shape after precipitation along the entire length; figure 6 - two blanks, part of the length of which is besieged, while the upset area is located in the middle part of the blanks; 7 - two blanks, in which the upset area is located on the single side.

Способ осуществл ют следующим образом .The method is carried out as follows.

Заготовки 1 и 2 уклащывают на плиту 3. В зависимости от.требуемой Blanks 1 and 2 are placed on slab 3. Depending on the required

Claims

25 product configurations between blanks provide for a gap of no more than two diameters, i.e. in some cases, the blanks of moss-ut 3Q contact the side surfaces;:. Further, a deformation force is applied to the blanks, Example. Two cylindrical blanks 1 and 2 of alloy AK4 with a diameter of 80 mm and a length of 950 rda are placed on a flat plate 3 so that they touch the side surfaces 4 (figl). The temperature of the tool 350 and the workpieces are 370C. Then, the whole flat length of the workpieces 3 and 1 to the required dimensions is simultaneously deposited with an upper flat plate. In the contact zone of the workpieces, the metal flow is limited, the length of the workpieces practically does not increase large resistance, the width of the blanks increased from the free ends to the midpoints and assumed the shape of an ellipse — with the long axis on the contact surfaces of the blanks. The broadening of the resulting blanks can be adjusted by changing their height F by applying lubricant to the plates or blanks. After dividing the block of blanks 1 and 2 along the surface of contact 4, two identical forgings are obtained (fig. In shape (half ellipse) and in size. This identity is consistently repeated if the dimensions and deformation conditions are identical. Such products are used as finished products forgings or as blanks for die forging, for example, shown in Fig. 4 ". When placing the blanks at a distance from each other, the blanks shown in Fig. 5 are obtained. In the case of deforming a part of the blanks, the products shown in Fig. b and 7, with This may be the location of the deformed area in the center or it may be moved in one direction or the other if necessary. Limit parameters of the method The length of the area being processed is at least 30% of the length of the workpieces and placed between them at a distance of two diameters accepted from obtaining the greatest effect from its use. So, for example, when the workpieces are located more than two diameters apart from each other, mutual restriction is manifested during deformation of more than 85%, as well as large deformations are practically not applied. With the deformation of the site with a length of less than 30%. the length of the workpiece does not provide the effect of mutual restriction. The use of the proposed method will significantly diminish the amount of forged products obtained by the progressive method. The invention method of simultaneous precipitation of blanks, including the laying of two identical cylindrical blanks parallel to each other on the tire and their joint deformation by force perpendicular to the longitudinal axis of the blanks, characterized in that, in order to widen the range of manufactured products, the blanks are laid with a gap between their side surfaces, not exceeding two workpiece diameters, and when jointly deformed, force is applied to workpieces of length not less than 30% of their length.
