[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a technical solution: Figures 1 to 4 As shown, in this embodiment, a bright furnace for metal heat treatment with a cooling structure includes a support frame 1, the upper end of the support frame 1 is fixedly connected to a bright quenching furnace 2, and an inlet and outlet 17 that crosses the bright quenching furnace 2 is opened on the side wall of the bright quenching furnace 2, rotating rollers 16 are rotatably installed on the inner walls of both ends of the support frame 1, and conveyor belts 3 are wound around the outer surfaces of the two rotating rollers 16. A driving mechanism acting on the rotating rollers 16 is provided on the support frame 1, the upper half of the conveyor belt 3 is located inside the bright quenching furnace 2, and the lower half of the conveyor belt 3 is located at the bottom of the bright quenching furnace 2, and a water spray plate 9 is suspended above the conveyor belt 3, and a plurality of water spray nozzles 19 are provided at the bottom of the water spray plate 9, and the plurality of water spray nozzles 19 are distributed in a linear array, and the upper end of the water spray plate 9 is connected to a water inlet pipe 18, and the upper end of the water spray plate 9 is fixedly connected to a movable block 7, and the movable block 7 is connected to the support frame 1 through an adjustment mechanism.

[0021] Among them, the adjustment mechanism is composed of a fixed vertical plate 4, a screw 5, a guide rod 6, a guide block 8 and a No. 1 motor 10. The two fixed vertical plates 4 are fixedly connected to the two sides of the upper end of the support frame 1. The screw 5 is rotatably connected between the two fixed vertical plates 4. The screw 5 passes through the movable block 7 and is connected to the movable block 7 by threaded cooperation. The upper end of the movable block 7 is fixedly connected to the guide block 8. The guide block 8 is slidably penetrated by a guide rod 6. The two ends of the guide rod 6 are respectively fixedly connected to the two fixed vertical plates 4. The side wall of a fixed vertical plate 4 is fixedly connected to the No. 1 motor 10, and the output shaft of the No. 1 motor 10 is fixedly connected to the screw 5.

[0022] When in use, start the No. 1 motor 10 to drive the screw 5 to rotate. Under the restriction of the guide block 8 and the guide rod 6, the movable block 7 cannot rotate. When the screw 5 rotates, the movable block 7 will move along the direction of the guide rod 6, thereby driving the water nozzle 19 to move synchronously. The No. 1 motor 10 is controlled to circulate forward and reverse, and the water nozzle 19 can be controlled to circulate left and right above the conveyor belt 3 to spray water to cool the metal parts on the conveyor belt 3. The continuous movement of the conveyor belt 3 can ensure that the cooling water on the conveyor belt 3 will not flow back into the bright quenching furnace 2, and the cooling water on the conveyor belt 3 will fall on the ground when the conveyor belt 3 reaches the end of the conveyor belt 3. There is no need to worry about water accumulation. It should be noted that the length of the conveyor belt 3 is more than the length shown in the figure. The conveyor belt 3 drawn in the figure is only for the convenience of display. At the same time, the time taken by the water spray plate 9 to move from one end of the conveyor belt 3 to the other end is less than the time taken by the conveyor belt 3 to move the length of the water spray plate 9. Only in this way can it be ensured that the area sprayed by multiple water nozzles 19 can fully cover the conveyor belt 3.

[0023] Among them, the driving mechanism is composed of a No. 2 motor 11, a driving wheel 12, a driven wheel 13 and a transmission chain 14. The No. 2 motor 11 is fixedly connected to the inner wall of the support frame 1, the driving wheel 12 is fixedly connected to the output shaft of the No. 2 motor 11, the shaft end of the rotating roller 16 is fixedly connected to the driven wheel 13, the driving wheel 12 and the driven wheel 13 are both rotatably connected to the side wall of the support frame 1, and the outer surface of the driven wheel 13 of the driving wheel 12 is wrapped with the transmission chain 14 and meshes with the transmission chain 14.

[0024] When in use, the second motor 11 is started to drive the driving wheel 12 to rotate. Under the action of the transmission chain 14, the driven wheel 13 starts to rotate, thereby driving the rotating roller 16 to rotate, and then driving the conveyor belt 3 to move.

[0025] A water shielding plate 15 is arranged above the second motor 11 , and the water shielding plate 15 is fixedly connected to the side wall of the support frame 1 .

[0026] The water shielding plate 15 can protect the second motor 11 to prevent the cooling water falling from the conveyor belt 3 from soaking the second motor 11.

[0027] The diameter of the driving wheel 12 is smaller than the diameter of the driven wheel 13 .

[0028] Such arrangement can form a labor-saving gear set between the driving wheel 12 and the driven wheel 13, thereby reducing the stress on the output shaft of the second motor 11.

[0029] The utility model provides a bright furnace for metal heat treatment with a cooling structure, and the specific working principle is as follows:

[0030] When in use, start the No. 2 motor 11 to drive the driving wheel 12 to rotate. Under the action of the transmission chain 14, the driven wheel 13 starts to rotate, thereby driving the rotating roller 16 to rotate, and then driving the conveyor belt 3 to move, and the metal parts to be quenched are placed on the conveyor belt 3. The metal parts will be heated when passing through the interior of the bright quenching furnace 2. When the metal parts move to the bottom of the water spray plate 9, under the action of the driving mechanism, multiple water spray nozzles 19 will circulate left and right above the conveyor belt 3 to spray water to cool the metal parts on the conveyor belt 3. The continuous movement of the conveyor belt 3 can ensure the conveyor belt 3. The cooling water on the belt 3 will not flow back into the bright quenching furnace 2, and the cooling water on the conveyor belt 3 will fall on the ground when the conveyor belt 3 reaches the end of the conveyor belt 3, so there is no need to worry about water accumulation. It should be noted that the length of the conveyor belt 3 is more than the length shown in the figure. The conveyor belt 3 drawn in the figure is only for the convenience of display. At the same time, the time taken by the water spray plate 9 to move from one end of the conveyor belt 3 to the other end is less than the time taken by the conveyor belt 3 to move the length of the water spray plate 9. Only in this way can it be ensured that the area sprayed by the multiple water nozzles 19 can fully cover the conveyor belt 3;

[0031] The working principle of the driving mechanism is to start the No. 1 motor 10 to drive the screw 5 to rotate. Under the restriction of the guide block 8 and the guide rod 6, the movable block 7 cannot rotate. When the screw 5 rotates, the movable block 7 will move along the direction of the guide rod 6, thereby driving the water nozzle 19 to move synchronously. By controlling the No. 1 motor 10 to circulate forward and reverse, the water nozzle 19 can be controlled to circulate left and right above the conveyor belt 3.

[0032] Although 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.
