Heat treatment device for automobile steering pull rod

The invention discloses a heat treatment device for an automobile steering pull rod, which comprises a shell, two sliding grooves are formed in the inner wall, close to the back face, of the shell, sliding blocks are installed in the two sliding grooves in a sliding mode, connecting plates are fixedly connected to the two sliding blocks, and a transverse plate is fixedly connected between the two connecting plates; a plurality of transmission mechanisms used for evenly heating the steering pull rod body are fixed to the upper surface of the transverse plate, a heating plate used for heating the steering pull rod body is further fixed to the supporting base, and a water tank used for cooling the heated steering pull rod body is fixed to the inner bottom of the shell. A cooling mechanism for recycling cooling water in the water tank is also arranged at the bottom of the shell. Through the arrangement of the structures, intermittent self-deflection and forward feeding of the steering pull rod body occur, so that
