Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1

[0021] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The utility model provides a technical solution: a cooling water spraying device for heat treatment of special-shaped parts, including a support frame 1, two groups of arc plates 5 are rotatably connected to the middle part of the support frame 1, a plurality of groups of auxiliary nozzles 6 are surrounded by the inner part of the arc plates 5, a gear 11 is fixedly connected to the outer wall of one end of each group of arc plates 5, a fixed plate 7 is fixedly connected to one side of the support frame 1, a water collecting tank 22 is fixedly connected to the bottom of the support frame 1, a cold water tank 20 and a hot water tank 25 are fixedly connected to one end of the water collecting tank 22, and the hot water tank 25 and the cold water tank 20 are symmetrical.

[0022] A movable plate 9 is slidably connected inside the fixed plate 7, a rack 10 is fixedly connected above the movable plate 9, the rack 10 is meshed with a gear 11, a return spring 13 is fixedly connected to one end of the movable plate 9, and the other end of the return spring 13 is fixedly connected to the bottom of the support frame 1.

[0023] A motor 8 is fixedly connected to one end of the fixing plate 7 , and the motor 8 passes through the fixing plate 7 and is fixedly connected to the cam 12 . A three-way water pipe 17 is fixedly connected between the cold water tank 20 and the hot water tank 25 .

[0024] Based on the working principle of the special-shaped workpiece heat treatment cooling water spraying device of embodiment 1, when the special-shaped workpiece is to be heat-treated and cooled, the workpiece is moved between the two groups of arc plates 5 below the upper support frame 3 by the roller 2, and then the motor 8 and the water pump 18 are started. Starting the water pump 18 can supply water to the main nozzle 4 and the auxiliary nozzle 6. Starting the motor 8 can rotate the cam 12. During the rotation of the cam 12, the movable plate 9 slidingly connected to the inside of the fixed plate 7 is lifted up. When the movable plate 9 rises, it rises together with the rack 10. Since the rack 10 is meshed with the gear 11 on the outer wall of the arc plate 5, the gear 11 can rotate with the arc plate 5. While rotating, the auxiliary nozzle 6 will change its water spraying angle and position. When the cam 12 rotates to a lower position, the reset spring 13 will reset the movable plate 9. At this time, the arc plate 5 will be reset again under the drive of the gear 11, which can better spray the special-shaped workpiece and prevent the occurrence of dead angles in the spraying, which will cause some positions of the workpiece to not be sprayed and cause defective products.

[0025] Embodiment 2
