Изобретение относитс к Области иакатывани спиральных сверл.This invention relates to the field of spiral drills.
Известен способ изготовлени спиральных сверл, (В.ключающий операции образовани в-нутренних 1канало1В, завивки и накатывани стружечных канавок.There is a known method of making twist drills (B. including the operations of forming inside 1 channels 1B, curling and rolling chip flutes.
Снижение трудоемкости изготовлени внутренних каналов достигаетс тем, что их получают путем продольной прокатки стружечных канавок на трубе с последующей сваркой стенок в перемычке заготовки, а затем осуществл ют завлеку по спирали.The reduction in the labor intensity of fabricating the internal channels is achieved by the fact that they are obtained by longitudinal rolling of chip grooves on the pipe, followed by welding of the walls in the web of the workpiece, and then pulling in a spiral.
Технологический процесс строитс следующим образом. Разрезают трубу на мерные заготовки; дл онистки от окалины внутреннюю полость трубы обдувают дробью, продольной прокаткой профилированными роликами на трубе образуют стружечные ,кана1вки с перемычкой по оси заготовки, сваривают стенки перемычки, отжигают заготовку, завивают сверло по спирали, производ т термообработку, а затем окончательную механическую обработку сверла.The process is constructed as follows. Cut the pipe into dimensional workpieces; To clean the scale, the internal cavity of the pipe is shot with a fraction, longitudinally rolling profiled rollers on the pipe form a chip, grooves with a bridge along the axis of the workpiece, weld the walls of the bridge, anneal the workpiece, curl the drill, produce heat treatment, and then final machining of the drill.
