Rotating disc type automatic quenching device

Abstract

The invention discloses a rotating disc type automatic quenching device, and belongs to the technical field of heat treatment equipment. The rotating disc type automatic quenching device comprises a rotating disc. The rotating disc is driven by a driving device and is horizontally arranged. At least three slipways are uniformly distributed on the rotating disc and around the central axis of the rotating disc. Pushing rods capable of sliding up and down along the slipways are arranged in the slipways. A quenching induction coil and a cooling pipe orifice are sequentially arranged on the rotating disc in the rotating direction of the rotating disc, are arranged on the movement loci of the pushing rods and are respectively opposite to the two adjacent pushing rods. A motor, driven by a pneumatic cylinder II to move up and down, is arranged below the rotating disc and at a corresponding position of the quenching induction coil. A quick connecting device for transmitting torque is arranged at the upper end of an output shaft of the motor and the lower ends of the pushing rods. Heating, cooling and taking and placing of parts are conducted synchronously and do not affect one another, the quenching efficiency is improved greatly, and besides, quenching parts uninterruptedly rotate at constant speed in the quenching induction coil along with the pushing rods, and are guaranteed to be heated more uniformly.

Description

technical field [0001] The invention relates to a quenching device, in particular to an automatic quenching device, which belongs to the field of heat treatment equipment. Background technique [0002] At present, the domestic industry generally adopts manual high-frequency quenching, or non-professional semi-automatic numerical control high-frequency quenching, which mainly uses manual induction heating and quenching of metal workpieces one by one on the quenching machine, or quickly Immersed in a water pool (oil pool) for cooling, due to manual operation, it is impossible to control the continuity of rapid heating of metal workpieces, it is difficult to control the size of the quenching hardness transition zone of metal workpieces, and it is also difficult to ensure the internal distribution of the hardened layer and the high frequency The uniformity of quenching hardness results in low yield and poor effect of metal quenching treatment.
