Description
Изобретение относитс к обработка металлов давлением и может быть использовано при разделении металлических . заготовок на мерные длины. Известен способ разделени металйических заготовок, включающий нанесение на заготовку концентратора напр жений, охрупчиВание заготовки в плоскости нанесенного концентратора напр жений и приложение разрушающей нагрузки l . Недостатком известного способа вл етс низкое качество получаемых заroTOBOKi так как охрупчивание производит с без учета на темпер хлад ноломкости типа металла, его структуры , и характера напр женного состо ни , возникающего при разделении. Цель изобретени повышение качества получаемьис заготовок. Поставленна цель достигаетс тем, что в способе разделени металлических заготовок, включающем нанесение на заготовку концентратора напр жений, охрупч ванке заготовки в плоскости нанесенного. |концентратора налр5гжений и приложение разрушающей нагрузки, охрупчквание производ т при температуре ниже шокней температуры хладноломкости заготовки с концентратором напр жений, но вьше верхней температуры хладноломкости той же заготовки без концентратора напр жений . Способ осуществл ют следующим обра-г зом. Заготовку из хладноломкого металла (сплава) любого сечени с предварительно нанесенным концентратором напр жений подвергают термообработке (натреву или. охлаждению в зависимости от исходной температуры заготовки), котора обеспечивает получение температуры по всему сечению данного металла заготовки , не превыщающей Т дл заготовки с концентратором напр жений и одновременно не более низкий, чем Т дл заготовки без концентратора напр жений. Соответствующие зан чени ТД и Т б&рут из справочной технической литератуThe invention relates to the processing of metals by pressure and can be used in the separation of metal. blanks for measuring lengths. A known method for separating metal blanks includes applying a stress concentrator to the workpiece, embrittling the workpiece in the plane of the applied stress concentrator and applying a breaking load l. The disadvantage of the known method is the low quality of the obtained roTOBOKi, since the embrittlement takes place without taking into account the cold temperature of the type of metal, its structure, and the nature of the stress state that occurs during separation. The purpose of the invention is improving the quality of the blanks. This goal is achieved by the fact that in the method of separating metal blanks, including applying a stress concentrator to the workpiece, it is more fragile to the blank billet. The hub of the hub and the application of the breaking load, the hardening is carried out at a temperature below the cold temperature of the billet of the workpiece with a stress concentrator, but higher than the upper hardening temperature of the same billet without the stress concentrator. The method is carried out as follows. A billet of a cold-breaking metal (alloy) of any cross-section with a pre-applied stress concentrator is subjected to heat treatment (natures or cooling depending on the initial temperature of the workpiece), which ensures the temperature throughout the cross section of this metal workpiece not exceeding T for a workpiece with a stress concentrator and at the same time no lower than T for a workpiece without a stress concentrator.
