Description

(54) СПОСОБ ШТАМПОВКИ ДЕТАЛЕЙ С ВНУТРЕННЕЙ РЕЗЬБОЙ(54) METHOD FOR STAMPING DETAILS WITH INTERNAL THREAD

кием жидкость производит раздачу поковки на 0,4 мм по диаметру, после чего резьбообраэующие пуансоны свободно вывинчиваютс . Степень раздачи выбирают, сообразу сь с величиной тепловой учадки детали при охлаждении от температуры окончани  штамповки, что дл  деталей из конструкционных углеродистых сталей составл ет 0,5-1% от номинального размера поперечного сечени .The cue fluid dispenses the forgings 0.4 mm in diameter, after which the thread-forming punches are unscrewed freely. The degree of distribution is chosen according to the heat value of the part during cooling from the temperature of the stamping end, which for structural carbon steel parts is 0.5-1% of the nominal cross-sectional size.

Использование предлагаемого способа штамповки обеспечивает .пбвышение производительности и экономию материалов, по сравнению с механической обработкой внутренних резь возможность получени  внутренних винтовых канавок с большим углом наклона и более точных, чем на прессованных профил х, а также возможность одновременное штамповки нескольких внутренних резьб на дета/ХХХ/Л //WV/Using the proposed method of punching provides an increase in productivity and savings of materials, compared with machining of internal threads, the possibility of obtaining internal helical grooves with a large angle of inclination and more accurate than on extruded profiles, as well as the possibility of simultaneous stamping of several internal threads on the part / XXX / L // WV /
