[0022] The above scheme arranges the material rack 9 on the left and / or right side of the heat treatment furnace 1, and arranges the water cooling pool 2 on the front side of the heat treatment furnace 1. At the same time, the vertical lifting and moving function of the support claw 8 is realized by the lifting frame 7, the front and rear movement function of the support claw 8 is realized by the conveying frame 6, and the left and right movement function of the support claw 8 is realized by the transfer frame 4.

[0023] Regarding the specific use process, the workpieces are generally stacked on the material rack 9. When heat treatment is required, the lifting frame 7 drives the claws 8 to the height corresponding to the material rack 9, and the transfer frame 4 drives the conveyor frame 6 to a position facing the material rack 9, and then the conveyor frame 6 drives the lifting frame 7 to move backward, so that the claws 8 take the workpiece on the material rack 9, and then the conveyor frame 6 moves forward and resets, and the transfer frame 4 moves the conveyor frame 6 to a position facing the heat treatment furnace 1, and then the conveyor frame 6 drives the lifting frame 7 to move backward, so that the claws 8 send the workpiece into the heat treatment furnace. Furnace 1, then the conveyor frame 6 moves forward and resets, the heat treatment furnace 1 heats the workpiece, after the heat treatment is completed, the conveyor frame 6 drives the lifting frame 7 to move backward, so that the claws 8 take the workpiece in the heat treatment furnace 1, then the conveyor frame 6 moves forward and resets, the lifting frame 7 drives the claws 8 down to the water cooling pool 2 for cooling, after the cooling is completed, the lifting frame 7 drives the claws 8 to rise, the transfer frame 4 moves the conveyor frame 6 to a position facing the material rack 9, and then the conveyor frame 6 drives the lifting frame 7 to move backward so that the workpiece on the claws 8 is put back on the material rack 9.

[0024] In this embodiment, there are two transfer guide rails 3 and they are respectively arranged on the front edge and the rear edge of the water cooling pool 2. The front and rear sides of the transfer rack 4 are respectively slidably connected to the two transfer guide rails 3. The transfer rack 4 is provided with a transfer drive 41, which is used to drive the transfer rack 4 to move on the transfer guide rail 3, thereby ensuring that the transfer rack 4 moves more smoothly on the transfer guide rail 3.

[0025] The transfer drive 41 preferably includes a transfer motor and a transfer wheel. The transfer motor is installed on the transfer frame 4. The transfer wheel is connected to the output shaft of the transfer motor and its axis is vertical. The rim of the transfer wheel abuts against the transfer guide rail 3. Therefore, when the transfer motor drives the transfer wheel to rotate, the transfer frame 4 can move along the transfer guide rail 3 due to the friction between the rim of the transfer wheel and the transfer guide rail 3. It should be understood that the transfer drive 41 can also be in other forms in the prior art, such as a ball screw motor pair that is parallel to the transfer guide rail 3 and fixed, and the transfer frame 4 is provided with a screw table that matches the ball screw motor pair; or the transfer drive 41 includes a synchronous motor and a synchronous belt along the left and right directions, and the synchronous motor drives the synchronous belt to move in the left and right directions, and the transfer frame 4 is connected to the synchronous belt.

[0026] In this embodiment, the transfer rack 4 includes a horizontal bar 401 arranged in the left and right directions and two longitudinal bars 402 arranged in the front and back directions. The left and right ends of the horizontal bar 401 are respectively connected to the rear ends of the two longitudinal bars 402. There are two conveying rails 5 and they are respectively arranged on the two longitudinal bars 402. The conveying rack 6 is located between the two longitudinal bars 402, and the left and right sides of the conveying rack 6 are respectively slidably connected to the two conveying rails 5. The conveying rack 6 is provided with a conveying drive 61, which is used to drive the conveying rack 6 to move on the conveying rail 5, thereby ensuring that the conveying rack 6 moves more smoothly on the conveying rail 5.

[0027] The conveying drive 61 includes a conveying motor and a conveying wheel. The conveying motor is installed on the conveying frame 6. The conveying wheel is connected to the output shaft of the conveying motor and its axis is vertical. The rim of the conveying wheel abuts against the conveying guide rail 5. Therefore, when the conveying motor drives the conveying wheel to rotate, the conveying frame 6 can move along the conveying guide rail 5 due to the friction between the rim of the conveying wheel and the conveying guide rail 5. It should be understood that the conveying drive 61 can also be in other forms in the prior art, such as a ball screw motor pair that is fixedly arranged parallel to the conveying guide rail 5, and the conveying frame 6 is provided with a screw table that cooperates with the ball screw motor pair; or the conveying drive 61 includes a synchronous motor and a synchronous belt along the left and right directions, and the synchronous motor drives the synchronous belt to move in the left and right directions, and the conveying frame 6 is connected to the synchronous belt.

[0028] In this embodiment, the lifting frame 7 is equipped with a lifting drive 71, which includes a lifting motor and a pull belt. The lifting drive 71 is mounted on the upper end of the lifting frame 7. One end of the pull belt is connected to the output shaft of the lifting motor and the other end is connected to the lifting frame 7. When the lifting motor drives the pull belt to wind up, the lifting frame 7 rises; when the lifting motor drives the pull belt to unwind, the lifting frame 7 descends. The pull belt is less affected by the water cooling pool 2. Of course, the lifting drive 71 can also be a vertically arranged ball screw motor pair or a pneumatic cylinder.

[0029] In this embodiment, there are two supporting claws 8 , which are parallel and spaced apart, thereby achieving stable support for the workpiece.
