Изобретение относитс к обработке металлов давлением и может быть использовано дл изготовлени секторного инструмента, в частности матриц дл высадки.The invention relates to the processing of metals by pressure and can be used for the manufacture of a sectoral tool, in particular, die-up matrices.
Известен способ изготовлени банджированных секторных матриц, заключающийс в изготовлении бандажа и твердосплавной цельной вставки с центральным отверстием, установке цельной вставки в бандаж и последующем разрывании вставки на секторы lA known method of manufacturing banjikirovannyh sector matrices, which consists in the manufacture of a bandage and carbide solid insert with a central hole, the installation of a solid insert in the bandage and the subsequent tearing of the insert into sectors l
Однако данный способ не обеспечивает достаточно высокого качества изготовлени матриц.However, this method does not provide a sufficiently high quality of matrix fabrication.
Цель изобретени - повышение качества изготовлени матриц.The purpose of the invention is to improve the quality of manufacturing matrices.
Дл достижени цели перед установкой цельной вставки в бандаж ее шлифуют по наружной поверхности и. , торцам, а на стенки центрашьного отверсти в местах предполагаемых разрывов вставки на секторы нанос т концентраторы напр жений.To achieve the goal, before installing the whole insert into the bandage, it is ground on the outer surface and. , the ends, and stress concentrators are applied to the sectors at the center hole in the places of the supposed insertion ruptures.
Изготавливают бандажированную секторную матрицу дл холодной высадки шестигранных.гаек.A banded sector matrix is made for cold heading of hexagonal.
Бандаж из стали ЗОХГСА изготавливают обработкой резанием с последующей термообработкой и шлифовкой.The bandage from ZOHHSA steel is made by machining followed by heat treatment and grinding.
Цельна вставка из твердого сплава ВК20 с шестигранной полостью, полученна путем спекани , шлифуетс по наружному диаметру и торцам. Затем вставка устанавливаетс на электроэрозионном станке и- в углах шестигранной полости проволокой диаметром 0,1-0,2 мм делают надрезы на глубину 0,5-1 мм. После этого вставка устанавливаетс в оградительное кольцо.Во внутрь вставки запрессовываетс жесткий стержень, что вызывает разрыв цельной вставки на шесть секторов.A solid carbide BK20 insert with a hexagonal cavity, obtained by sintering, is polished on the outer diameter and ends. Then the insert is installed on the EDM machine and, in the corners of the hexagonal cavity, make cuts to a depth of 0.5-1 mm with a wire of 0.1-0.2 mm in diameter. Thereafter, the insert is installed in a protective ring. A rigid rod is pressed inward into the insert, which causes the entire insert to break into six sectors.
