Предложена методика определения оптимальных углов волочильного инструмента для трехкомпонентной заготовки, учитывающая наличие калибрующего пояска волоки и обеспечивающая минимальное значение напряжения волочения. Показано влияние технологических параметров на величину оптимальных углов конусности технологического инструмента. Для стандартных волок с фиксированным углом конусности получено соотношение для расчета оптимальной вытяжки, обуславливающей минимальные значения напряжения волочения.

A procedure of determining the optimal angles of the drawing tool for a three-component billet, which takes into account the presence of the finishing die cylinder and provides a minimal drawing stress, is proposed. The influence of manufacturing parameters on the magnitude of optimal conicity angles of the manufacturing tool is shown. The relationship for the calculation of the optimal drawing, which provides minimal drawing stress, is found for standard dies with a fixed conicity angle.
