(54) ОПРАВА ДЛЯ КРЕПЛЕНИЯ АЛМАЗНЫХ ВОЛОК(54) RIMS FOR STRETCHING DIAMOND HAIR
I ... ,.. I ..., ..
Изобретение относитс к области произ- водства волочильного инструмента. Прей- . мущественна область применени - закрепление алмазов в оправы.;The invention relates to the production of a drawing tool. Rey- important area of application - fixing diamonds in the rim .;
Закрепление алмазов в оправы обеспе- . чивает удобное обращение с ними при установке на волочильных машинах. Оправа.необходима и при закреплении алмазов на полированных станках при восстановительном ремонте. Одновременно оправа играет роль скрепл ющего обруча, благодар чему по- ю вышаетс стойкость хрупких алмазов на растрескивание. ,.Fastening diamonds in the rim provided. Ensures that they can be handled conveniently when mounted on wire-drawing machines. A frame is also needed when fixing diamonds on polished machines during reconditioning. At the same time, the rim plays the role of a bonding hoop, thereby enhancing the resistance of fragile diamonds to cracking. ,

Дл предотвращени разрыва кристалл1а при волочении необходимо, чтобы при закреплении материал промежуточногр сло 15 плотно охватывал с, боковых сторон всю иеровную поверхность алмаза. Нижн опор на поверхность кристалла должна плотно прилегать к дну оправы. Желательно, чтобы коэффициент линейного расщиренй материала промежуточного сло и оправы был близок к коэффициенту линейного расширени алмаз.а. В качестве промежуточных слоев при закреплении алмаза и дл изготовлени оправ примен ют различнь1е материалы 1.In order to prevent the crystal 1a from breaking during drawing, it is necessary that, during fixing, the material of the intermediate layer 15 should tightly cover the entire diamond surface of the diamond on its sides. The bottom support on the surface of the crystal should fit snugly to the bottom of the rim. It is desirable that the linear expansion coefficient of the material of the intermediate layer and the rim be close to the linear expansion coefficient of the diamond. Various materials 1 are used as intermediate layers for fixing diamond and for making frames.
. Наиболее близким по технической сущности к описываемому изобретению вл етс оправа дл креплени алмазных волок, выполненна в виде стакана, в торце которого выполнено отверстие дл прохода проволоки 2.. The closest in technical essence to the described invention is a frame for fastening diamond fibers made in the form of a glass, at the end of which a hole is made for the passage of wire 2.
Однако така оправа не обеспечивает хорошего заполнени промежуточным материалом полости между дном оправы и алмазом и ие обеспечивает одинаковой плотности промежуточного материала между алмазом , стенками и дном оправы, что снижает стойкость волок, так как происходит растрескивание алм1аза.However, such a frame does not provide a good filling of the intermediate material of the cavity between the bottom of the frame and the diamond and it does not provide the same density of the intermediate material between the diamond, the walls and the bottom of the frame, which reduces the durability of the fiber, because of the cracking of the diamond.
, Цель изобретени - улучшение качества креплени алмаза в оправе.The purpose of the invention is to improve the quality of fastening a diamond in the frame.
Поставленна цель достигаетс тем, что в оправе дл креплени алмазных волок, выполненной в виде стакана, в торце которого имеетс отверстие дл прохода проволоки , внутренн поверхность торца выполнена в виде усеченного конуса, причем угол при вершине конуса составл ет 90-150°, а диаметр меньшего основани конуса равен диаметру опорной поверхности волоки.This goal is achieved by the fact that in the frame for fastening diamond fibers made in the form of a glass, at the end of which there is a hole for wire passage, the inner surface of the end is made in the form of a truncated cone, the angle at the apex of the cone is 90-150 ° and the diameter the smaller base of the cone is equal to the diameter of the die drawing surface.
