Abstract
Изобретение относитс к устройству дл прессовани изделий из порошка с профильными углублени ми на наружной поверхности. Цель - повышение качества издели за счет исключени дефектов боковой поверхности. Пресс-форма заполн етс порошком с помощью питател . При ходе пуансона 1 вниз осуществл етс двухстороннее прессование порошка при перемещении матричной плиты в направлении перемещени верхнего пуансона - в непод вижном выталкивателе 3. Ход прессовани заканчиваетс , когда нижний торец матрицы 6 упираетс в ступень выталкивател 3. Боковое давление при прессовании порошка замыкаетс через разъемную матрицу 6 на призматическую поверхность Б обоймы 4. При обратном ходе пуансона 1 осуществл ют выталкивание издели 10. При выталкивании издели ступень выталкивател 3 перемещает матрицу по направл ющим наклонных поверхностей Б обоймы 4. После полного раскрыти матрицы изделие свободно удал етс . 2 ил., 1 табл. Т г (Л СThe invention relates to a device for pressing powder articles with shaped recesses on the outer surface. The goal is to improve product quality by eliminating side surface defects. The mold is filled with a powder using a feeder. When the punch 1 is pushed down, the powder is compacted two-way when the matrix plate is moved in the direction of the upper punch - in the stationary ejector 3. The pressing course ends when the bottom end of the matrix 6 abuts on the ejector stage 3. Lateral pressure during pressing of the powder closes through the separable matrix 6 on a prismatic surface B of the yoke 4. During the return stroke of the punch 1, the product 10 is pushed out. When the product is pushed out, the ejector stage 3 moves the die along the guides of the inclined surfaces B of the yoke 4. After the matrix is fully opened, the product is freely removed. 2 ill., 1 tab. T g (L S
