Изобретение относитс к обработке металлов давлением, в частности к способам деформировани с нагревом за счет трени .The invention relates to the processing of metals by pressure, in particular, to methods of deformation with heating by friction.

Известен способ изготовлени изделий путем воздействи на заготовку деформирующим инструментом, установленным с возможностью вращательного движени при нагреве заго товки трением 1 .A known method of manufacturing products by acting on the workpiece with a deforming tool, installed with the possibility of rotational movement when the preform is heated by friction 1.

Недостатком известного способа вл етс невозможность получени издели с внутренним рельефом.A disadvantage of the known method is the impossibility of obtaining an article with an internal relief.

Цель изобретени - получение изделий с внутренним рельефом.The purpose of the invention is the production of articles with internal relief.

Дл достижени указанной цели согласно способу изготовлени изделий путем воздействи на заготовку деформирующим инструментом , установленным с возможностью вращательного движени при нагреве заготовки трением, перед воздействием на заготовку деформирующим инструментом.To achieve this goal according to the method of manufacturing products by acting on the workpiece with a deforming tool, installed with the possibility of rotational motion when the workpiece is heated by friction, before the workpiece is subjected to a deforming tool.

на ее наружной поверхности выполн ют канавки.grooves are made on its outer surface.

На фиг. 1 схематически изображена заготовка перед деформированием; на фиг. 2 - то же, после деформировани .FIG. 1 schematically shows the workpiece before deformation; in fig. 2 - the same after deformation.

Способ реализуетс следующим образом .The method is implemented as follows.

На прутковой заготовке 1, имею10 щей диаметр d, выполн ют рельеф, например в виде чередующихс выступов А шириной Ь и канавок Б глубиной h, после чего сообщают заготовке вращательное движение с опре )5 деленной скоростью W и воздействуют на ее прошивнем 2 в осевом направлении определенным усилием Р.On a bar stock 1 having a diameter d, a relief is made, for example, in the form of alternating protrusions A of width b and grooves B with depth h, then the rotational motion is given to the workpiece with a defined velocity W and pierced by 2 in the axial direction a certain effort R.

Claims

Under the action of the heat of friction of the metal, the billet is heated to a plastic state and is deformed, as a result of which the billet is pierced and distributed to the inner and outer diameter. 3.9 Since the size of the internal distribution depends on the ratio of the dimensions of the cross section of the workpiece and the working face of the piercing, there are more distribution in the parts of the workpiece where the grooves are made, which leads to the formation of internal grooves B on the resulting product (Fig. 2). PRI me R. A bar stock made of brass brand L S3 with a diameter of 1) mm is clamped and the lathe chuck and stitch on it 2 grooves with a width of mm and a depth of mm in alternation with. Two ledges with a width of mm. Rotating the workpiece at a speed of 2000 rpm, an axial load equal to 3 kg / mm is applied to its end face by means of a piercing having a diameter of mm, the workpiece is heated by friction and its firmware. With a working stroke of 50 mm, a hollow product with a hole, 5 mm, and two internal grooves with dimensions, 9 mm mm and outer diameters d 16 mm and mm, is obtained. Compared with the known method, the proposed method allows to obtain hollow parts with internal relief. The invention The method of manufacturing products by acting on the workpiece with a deforming tool, installed with the possibility of rotational movement when the workpiece is heated by friction, is due to the fact that, in order to obtain products with internal relief, before the work on the workpiece with a deforming tool on its outer surface grooves.
