[0025] The driving clamping mechanism 2 is arranged on the furnace body 1. The driving clamping mechanism 2 includes a servo motor 21. The servo motor 21 is installed on the top of the furnace body 1. The bottom end of the output shaft of the servo motor 21 passes through the furnace body 1 and extends into the interior thereof. The bottom end of the output shaft of the servo motor 21 is fixedly connected with a fixing column 22. Two slide grooves 23 are provided on the left and right sides of the fixing column 22. The top and bottom of the inner wall of the slide groove 23 are fixedly connected by a sliding rod 24. The surface of the sliding rod 24 is slidably connected with a slider 25. The two sliders 25 on the same side and the side away from each other are fixedly connected by a movable plate 26. The inner wall of the movable plate 26 is in contact with the surface of the fixed column 22, and an elastic member 27 is sleeved on the surface of the sliding rod 24. The elastic member 27 is made of a spring. A plurality of threaded rods 28 are threadedly connected on both sides of the top of the movable plate 26. A rotating block 29 is fixedly connected to the top of the threaded rod 28. The bottom end of the threaded rod 28 penetrates the movable plate 26 and extends to the outside thereof. A clamping block 210 is fixedly connected to the bottom end of the threaded rod 28. Two placement plates 211 are fixedly connected to the surface of the fixed column 22. A placement block 212 is fixedly connected to the top of the placement plate 211 and at the position corresponding to the clamping block 210.

[0026] Specifically, according to the size of the cast iron part, the distance between the clamping block 210 and the placing block 212 is adjusted, and the rotating block 29 is rotated. The rotating block 29 drives the threaded rod 28 to move upward or downward, and the threaded rod 28 drives the clamping block 210 to move upward or downward, so as to clamp the cast iron parts of different sizes, such as Figure 3 Status shown.

[0027] By means of the cooperation of the servo motor 21, the fixed column 22, the slide groove 23, the slide rod 24, the slider 25, the movable plate 26, the elastic member 27, the threaded rod 28, the rotating block 29, the clamping block 210, the placement plate 211 and the placement block 212, the workpieces are prevented from piling up when they are placed in the tempering furnace for heating, so that the workpieces can be separated and heated evenly, while ensuring the stability of the workpieces when they are heated, and facilitating the clamping and heating treatment of workpieces of different sizes, thereby improving the flexibility during use.

[0028] The waste heat utilization mechanism 3 is arranged on the furnace body 1. The waste heat utilization mechanism 3 includes a fixed shell 31. The fixed shell 31 is installed on the top of the right side of the furnace body 1. The left side of the top of the fixed shell 31 is fixedly connected with an exhaust fan 32. The top of the exhaust fan 32 is connected to the furnace body 1 through an air intake pipe 33. The bottom of the exhaust fan 32 is fixedly connected with a heat conduction pipe 34. The end of the heat conduction pipe 34 away from the exhaust fan 32 passes through the fixed shell 31 and extends to the outside. The right side of the inner wall of the fixed shell 31 is fixedly connected with a water temperature sensor 35.

[0029] Furthermore, a water supply pipe which is interconnected with the top of the right side of the fixed shell 31 is fixedly connected, and a drainage pipe which is provided with a valve is fixedly connected to the bottom of the fixed shell 31 .

[0030] Furthermore, the control methods of the servo motor 21, heater, exhaust fan 32 and water temperature sensor 35 are all controlled by the controller matched therewith, and the control circuit can be realized by simple programming by technicians in this field. It is common knowledge in this field and will not be elaborated here.

[0031] Specifically, when the heating in the furnace body 1 is completed, the exhaust fan 32 is started, and the exhaust fan 32 sucks out the hot air in the furnace body 1 through the air intake pipe 33 and the heat conduction pipe 34. The hot air in the heat conduction pipe 34 is subjected to heat absorption and cooling treatment through the water in the fixed shell 31, so that the water is heated. The temperature of the water is sensed by the water temperature sensor 35, and the detection signal is transmitted to the controller, so that the water temperature can be clearly understood, which is convenient for users to use.

[0032] Through the cooperation of the fixed shell 31, the exhaust fan 32, the air intake pipe 33, the heat pipe 34 and the water temperature sensor 35, it is convenient to recycle the excess heat after heating in the furnace body 1, thereby avoiding waste of resources.

[0033] When in use, the movable plate 26 is pulled upward, and the movable plate 26 drives the slider 25 to move upward, so that the slider 25 squeezes the elastic member 27 to move, so that the clamping block 210 and the placement block 212 are separated, and then the cast iron part is placed on the placement block 212, and then the elastic member 27 is released, and the elastic member 27 is caused to move downward by the elastic force of the elastic member 27 through the slider 25, so that the clamping block 210 and the placement block 212 clamp and fix the cast iron part, and then the servo motor 21 is started, and the servo motor 21 drives the fixed column 22 to rotate slowly through the output shaft, and then the heater is turned on to heat it evenly.

[0034] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
