The invention discloses a device and a process for
hot working of small-batch multi-specification camshafts, and belongs to the field of
camshaft heat treatment. The device comprises a
steel frame anda
workbench, wherein two lifting devices are symmetrically arranged on the steel frames located on the two sides of the
workbench, a rotary platform device is arranged on the
workbench, the camshaftis movably connected in the rotary platform device, a
cam is arranged on the
camshaft, the lifting devices are correspondingly connected with telescopic rods, the
tail end of one telescopic rod is connected with a peach tip
induction coil, the
tail end of the other telescopic rod is connected with a base circle
induction coil, an isolation plate is arranged between the peach tip
induction coil andthe base circle induction coil, and the workbench is provided with a PLC which is electrically connected with the lifting devices and the rotary platform device correspondingly. According to the device for
hot working of the small-batch multi-specification camshafts and the process adopting the device, the
quenching temperature and the depth of the hardened layer after
quenching of the peach tippart of the
cam are correspondingly same as the
quenching temperature and the depth of the hardened layer after quenching of the base circle part of the
cam, and the cams with different specificationscan be continuously heated.
