Изобретение относитс к обработке таллов давлением- и может быть использовано при изготовлении изделий- термофрикционной формовкой.The invention relates to the processing of tal by pressure - and can be used in the manufacture of products by thermofriction molding.

Известен способ изготовлени изделий термофрикционной формовкой путем воздействи на заготовку вращающимс относительно нее деформирующим инструментом,.вызывающего формообразование поверхности заготовки с, вытеснением ее металла l A known method of making products by thermofriction molding is carried out by acting on the workpiece with a rotating tool relative to it, which causes the forming of the surface of the workpiece, displacing its metal l

Недостатком известного способа вл етс невысокое KaiecTBO получаемых изделий из-за невысокой точности их изготовлени .The disadvantage of this method is the low KaiecTBO of the resulting products due to the low accuracy of their manufacture.

Цель изобретени - повшиение качества получаемых изделий за счет повышени точности их изготовлени .The purpose of the invention is to improve the quality of the products obtained by increasing the accuracy of their manufacture.

Дл достижени указанной цели в способе изготовлени изделий термофрикционной формовкой путем воздействи на заготовку вращающимс ,отнрсительно ее деформирующим инструментом вызыиающего формообразование заготовки с вытеснением ее Металла, одновременно с термофрикциочной формовкой заготовку подвергают обработке резанием, причем усилие 15езани создают преимущественно напором вытесн емого металла заготовки.In order to achieve this goal in the method of manufacturing products by thermofriction molding by acting on the workpiece with a rotating, relatively deforming tool causing the forming of the workpiece to displace its Metal, the workpiece is subjected to cutting, and the force of the casting 15 is created by the pressure of the displaced metal of the workpiece.

Circulation of the forged bar; FIG. 3 is a diagram of the thermofriction piercing of the workpiece with the groove of the outer surface of the shell and trimming the end; Fig. 40 shows a diagram of the thermofriction crimping of a tubular shank of a spindle valve with simultaneous trimming of its end face and groove of a spool rod of a valve.

В исходном состо нии (фиг.1 а) заготовка 1 закреплена в зажиМном устройстве 2, например в патроне токарного станка или машины дл сварки трением. Выступающийконец заготовки In the initial state (Fig. 1a), the workpiece 1 is secured in the clamping device 2, for example, in the chuck of a lathe or friction welding machine. Speaker end of the workpiece

0 помещен в углубление матрицы 3. На уровне противолежащего к заготовке торца матрицыпомещен подрезной ре-Зец 4, своей режущей кромкой полностью или частично перекрывающий за5 зор между заготовкой 1 и боковой поверхностью углублени матрицы 3.0 is placed in the cavity of the matrix 3. At the level of the matrix end opposite to the workpiece, there is a subcutting res-Zec 4, with its cutting edge completely or partially blocking the gap between the workpiece 1 and the lateral surface of the cavity of the matrix 3.

Заготовке 1 сообщают вргицательное движение с определенной урловой скоростью CJ и посредством матрицы 3 The workpiece 1 is reported on a movement with a certain url speed CJ and through a matrix 3

0, its end face acquires a size h in this case equal to the magnitude of the cavity 3. During thermofriction reduction and pipe crimping, the cutters are set behind a calibrated matrix and sizing the end of the formable rod (Fig. 2a). In the case of a thermofriction firmware, cutting the end of the shell with a size of is performed with a cutter installed in pier 5 of pier 6. By changing the position of the cutting edge of the incisors relative to the axis of rotation of the workpiece, the product is also processed on the outer surfaces (Figures 2, b, 36, 46) . PRI me R. Brass billet 1 with a diameter of d 9 mm is clamped in the chuck of a lathe and reported to it a rotational movement at a speed of r / min. By means of the matrix 3, installed in the tails of the machine’s tailstocks and having a recess in diameter. About 11 mm and depth h 6 mm, an axial load, 5 kg / mm, is applied to the end of the rotating workpiece, as a result of which the metal of the workpiece is heated due to the friction of plasticity and deformation, accompanied by its pressing into the gap between the walls of the cavity 3 and the workpiece 1. When the displaced metal leaves the end of the die 3, it is subjected to Processing by the cutter 4 at the same time as the deformation of the workpiece 1 continues, resulting in -. with a product with a terminal thickening having a diameter D of 11 mm and a height of I of 6 mm. The method allows to ensure high accuracy of the floor of the height of products due to the removal of excess metal volume of the workpiece in the bargie, thereby improving the quality of the products. The inventive ".- .. Method of manufacturing products by thermofriction molding by acting on the workpiece with a rotating tool relative to it, causing the surface of the workpiece to be molded and displaced. Its space has been swept, in order to improve the quality of the products obtained by increasing the accuracy of their manufacture , simultaneously with thermofriction molding, the billet is subjected to machining, and the cutting force is created mainly by the pressure of the displaced metal of the billet I source of information, the received note in the examination 1.
