Description

Technical Field

[0001] This utility model belongs to the field of forging heat treatment technology, and in particular relates to a heat treatment device for improving the cooling uniformity of forgings. Background Technology

[0002] A forging heat treatment apparatus is a device used to perform heat treatment processes on forgings. Through heating, holding, and cooling, it improves the microstructure and properties of forgings to meet different application requirements. A forging heat treatment apparatus typically includes the following main parts:

[0003] Heating components: Used to heat forgings to the required temperature. Various heating methods are available, including resistance heating, induction heating, and gas heating.

[0004] Heat treatment chamber: Used to hold forgings and perform heat treatment. The design of the heat treatment chamber must ensure temperature uniformity to guarantee that the forgings are heated evenly.

[0005] Cooling device: Used to cool the forgings after heating. Cooling methods include water cooling, oil cooling, and air cooling, and the specific choice depends on the material of the forging and the heat treatment requirements.

[0006] Control system: Used to monitor and adjust parameters such as temperature and time during the heat treatment process to ensure the accuracy and stability of the heat treatment process.

[0007] For example, Chinese patent CN218755859U discloses a water circulation cooling device for heat treatment of aluminum forgings, relating to the field of aluminum forging heat treatment technology. It includes a support column, with a top plate fixedly connected to the top of the support column. A water cooling mechanism is fixedly connected to the middle of the bottom of the top plate. The water cooling mechanism includes a pump head, which is fixed to the middle of the bottom of the top plate. A nozzle is fixedly connected to the bottom of the pump head. A water pipe is fixedly connected to one side of the pump head, and the bottom of one side of the water pipe is fixed to one side of a water tank. The water pipe and the inside of the water tank are connected. A water pump is fixedly connected to one side inside the water tank, and the output end of the water pump is connected to the water pipe. Conveying mechanisms are fixedly connected to both sides of the top of the water tank. This invention uses a wind-cooled motor to drive a rotating column, which in turn drives a fan blade to rotate. This achieves simultaneous air cooling of the aluminum forgings and cooling of the sprayed water, resulting in a dual cooling effect and better cooling performance.

[0008] The aforementioned patent has the following problems:

[0009] This patent has some drawbacks in its use. For example, while the aforementioned cooling device can cool forgings, the water spraying position is fixed, and multiple motors are needed to drive multiple fan blades, resulting in high electricity costs for production. Furthermore, the surface of the forging cannot be evenly sprayed with water, affecting the uniformity of cooling and reducing product quality. Therefore, we propose a heat treatment device to improve the cooling uniformity of forgings. Utility Model Content

The fourth sprocket is fixed to the output shaft of the motor. One end of the third sprocket passes through the inner wall of the second movable slot and extends into the top plate, where it is fixed to the top of another fan. A second chain meshes between the third sprocket and the fourth sprocket.

[0021] An extrusion assembly, located within a top plate, is used to extrude the first and second chains.

[0022] In this technical solution, it is ensured that the user can simultaneously drive the rotating rod and two fans to rotate.

[0037] 1. This heat treatment device for improving the cooling uniformity of forgings, through the setting of a rotating rod and a second gear, ensures that the rotating rod can drive the second gear to rotate on the bottom surface of the top plate. Through the setting of a rotary joint and a first gear, it ensures that water in the water cooling mechanism can enter the rotary joint. When the second gear rotates, it drives the first gear to rotate, causing the lower half of the rotary joint to rotate. Through the setting of a water pipe and atomizing nozzles, it ensures that when the first gear rotates, it drives the water pipe to rotate through the lower half of the rotary joint, causing the water pipe to rotate, causing multiple atomizing nozzles to rotate.

These are well known to those skilled in the art and therefore need not be elaborated upon.

[0073] Working principle:

[0074] In use, the user starts the motor 11, causing the output shaft of the motor 11 to drive the rotating rod 8 to rotate on the bottom surface of the top plate 2. The bottom end of the rotating rod 8 drives the second gear 9 to rotate, which in turn drives the first gear 5 to rotate. The first gear 5 then drives the lower half of the rotary joint 4 to rotate, which in turn drives the water pipe 6 to rotate. The water pipe 6 then drives multiple atomizing nozzles 7 to rotate. The user then activates the water cooling mechanism, which injects water into the rotary joint 4, through which it flows into the water pipe 6, and finally into the multiple atomizing nozzles 7, where it is atomized. The water is sprayed onto the outside environment so that it can be evenly sprayed onto the surface of the forging for cooling. When the user starts the motor 11, the output shaft of the motor 11 will drive the fourth sprocket 18 and the second sprocket 14 to rotate. The fourth sprocket 18 and the second sprocket 14 will drive the third sprocket 17 and the first sprocket 13 to rotate through the second chain 19 and the first chain 15, respectively. When the first sprocket 13 and the third sprocket 17 rotate, they will drive the two fans 10 to rotate on the bottom surface of the top plate 2, so that the two fans 10 can assist in cooling the forging. This ensures that the user can drive the rotating rod 8 and the two fans 10 to rotate at the same time.

[0075] In use, the user activates the two electric telescopic rods 23, causing one end of each electric telescopic rod 23 to drive the two sliders 21 to move along the two slides 20, which in turn drive the two tensioning wheels 22 to move, causing the two tensioning wheels 22 to press the first chain 15 and the second chain 19 respectively, ensuring that the user can adjust the tension of the first chain 15 and the second chain 19.
