Abstract

Изобретение относитс к устройствам дл резки пруткового материала на заготовки , в частности дл резки прутков в ротор- ных лини х, и позвол ет повысить надежность в работе устройства. При вращении вала 1 торцовый кулачок 4, взаимодейству со штоком 21, перемещает его вверх. Шток 21 через рычаг 22 и муфту 23 поворачивает ролик 24 и подает прутковую заготовку 29 до упора 15 на позицию отрезки . При этом палец жестко фиксирует положение ножа 6 по пазу 10. Отрезанна от прутка заготовка 29, удерживаема ножом 6, транспортируетс в зону перегрузки, а нож 6 возвращаетс на исходную делительную окружность с помощью пружин 9. Затем в зоне перегрузки штоки 18 и 19, жестко удержива заготовку, перемещают ее вниз на линию взаимодействи с транспортным ротором, обеспечива надежную передачу в захваты транспортного ротора. 2 ил.The invention relates to devices for cutting bar material into blanks, in particular for cutting rods in rotary lines, and makes it possible to increase the reliability of operation of the device. When the shaft 1 rotates, the face cam 4, interacting with the rod 21, moves it upwards. The rod 21 through the lever 22 and the clutch 23 rotates the roller 24 and delivers the bar stock 29 up to the stop 15 at the cut position. In this case, the finger rigidly fixes the position of the knife 6 along the groove 10. The workpiece 29 cut off from the rod, held by the knife 6, is transported to the overload zone, and the knife 6 returns to the initial pitch circle using springs 9. Then, in the overload zone, the rods 18 and 19 are rigidly holding the workpiece, move it down to the line of interaction with the transport rotor, ensuring reliable transfer to the grippers of the transport rotor. 2 Il.
