Description

Предлагаема  пресс-форма предназначена дл  прессовани  винтовых пластинок из твердых сплавов способом поперечного и продольного прессовани . Предлагаема  пресс-форма позвол ет автоматизировать процесс прессовани , включа  операции заполнени , пресс-формы смесью и выталкивани , отпрессованных пластинок. Это достигаетс  тем, что пресс-форма снабжена поворотным, развращенным в кольцевом пазу матрицы питателем и взаимодействующим с ним выбрасывателем, перемещающимис  по спиральному пазу направл ющей, установленной на сердечнике пресс-формы.The proposed mold is designed for pressing screw plates of hard alloys by the method of transverse and longitudinal pressing. The proposed mold allows the automation of the pressing process, including the filling operation, the mold with the mixture and the extrusion, of pressed plates. This is achieved by the fact that the mold is provided with a rotary feeder corrupted in the annular groove of the matrix and an ejector interacting with it, moving along the spiral groove of a guide mounted on the core of the mold.

На чертеже изображена предлагаема  пресс-форма в двух проекци х .The drawing shows the proposed mold in two projections.

Пресс-форма выполнена в виде полой цилиндрической матрнцы 1, в которой с помощью сердечника 2 создаетс  кольцева  рабоча  полость . В рабочей полости помещены дза нодвижных пуапсона 5, представл юш ,ие собой цилиндрические сегменты с винтовыми рабочими поверхност ми , которым сообщаетс  возвратно-вращательное движение в плоскости, перпендикул рной к оси пресс-формы .The mold is made in the form of a hollow cylindrical matrices 1, in which an annular working cavity is created with the help of the core 2. In the working cavity, there are placed three moving poapson 5, which is a cylindrical segment with screw working surfaces, which is associated with a reciprocating rotational movement in a plane perpendicular to the mold axis.

Формирование боковых винтовых поверхностей прессуемых пластинок в замкнутой кольцевой полости пресс-сЬормы осуществл етс  за счет встречного кругового движени  пуансонов.The formation of the side screw surfaces of the compression plates in the closed annular cavity of the press mold is carried out by means of a counter-circular movement of the punches.

Встречпое движение пуансонов и нх возврат в исходное положение производитс  при помощи двух т г 4, перемещающихс  в прорези матрицы , шарпирно св занных с пуансонами и наход щихс  под воздействием вращающегос  кулачка 5.The reciprocal movement of the punches and their return to the initial position is carried out with the help of two tons of 4 moving in the slits of the die, which are sharply associated with the punches and under the influence of the rotating cam 5.

Порощкова  смесь засыпаетс  в рабочую полость через питатель 6 и продольную щель в матрице, закрываемую поворотной сегментной крыщкой 7 со сквозным пазом, получающей движение при помощи т ги 8 от отдельного привода. Этим осуществл етс  периодическа  дозировапна  загрузка пресс-формы порошковой смесью.The powder mixture is poured into the working cavity through the feeder 6 and the longitudinal slit in the die, which is closed by a rotatable segment flap 7 with a through groove, which is driven by the pull rod 8 from a separate drive. This is carried out periodically dosing the loading of the mold powder mixture.
