Description

Technical Field

[0001] This utility model relates to the field of rapid cooling forging technology, and in particular to a rapid cooling forging in the heat treatment process. Background Technology

[0002] Heat treatment is one of the important means to improve the performance of forgings. By performing appropriate heating, holding, and cooling operations on forgings, their internal crystal structure, phase composition, and residual stress distribution can be adjusted, thereby significantly improving the mechanical properties of the forgings. Different heat treatment processes can endow forgings with different performance characteristics to meet the needs of various practical applications. Therefore, it is necessary to design a rapid cooling forging process during heat treatment.

[0003] Most existing cooling devices for forgings use conventional cooling methods, which can easily lead to inconsistent cooling rates in different parts of the forging. Uneven cooling can generate significant thermal and structural stresses within the forging, resulting in serious quality defects such as deformation and cracking. This reduces the product yield and production efficiency. Furthermore, water cooling alone is difficult to control precisely due to its strong cooling capacity. Therefore, air cooling following water cooling allows for a relatively stable cooling transition phase after rapid cooling. This helps to gradually release the thermal stress within the forging, reducing the risk of deformation and cracking caused by thermal stress concentration, and improving the dimensional accuracy and quality stability of the forging. Utility Model Content

[0004] The purpose of this invention is to provide a method for rapidly cooling forgings during heat treatment. This addresses the problems mentioned in the background section, where existing forging cooling devices mostly employ conventional cooling methods, which easily lead to inconsistent cooling rates across different parts of the forging. Uneven cooling generates significant thermal and structural stresses within the forging, resulting in serious quality defects such as deformation and cracking, reducing product yield and production efficiency. Furthermore, water cooling alone is problematic due to its strong cooling capacity and difficulty in precisely controlling the cooling rate. Therefore, air cooling following water cooling allows for a relatively stable cooling transition phase after rapid cooling. This helps to gradually release internal thermal stresses, reducing the risk of deformation and cracking caused by stress concentration, and improving the dimensional accuracy and quality stability of the forging.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapidly cooled forging during heat treatment, comprising a conveyor frame, a water-cooled box installed on the upper left side of the conveyor frame, the water-cooled box having an internal cavity, a water-cooling mechanism installed on the upper inner wall of the cavity, an air-cooled box installed on the right side of the top surface of the conveyor frame, the air-cooled box having an internal cavity, a rotating mechanism rotatably connected inside the cavity, the water-cooling mechanism including a water spray pipe installed on the upper inner wall of the cavity, several pressurized nozzles penetrating the bottom of the water spray pipe, a water supply pipe penetrating the right end of the water spray pipe, a water pump penetrating the end of the water supply pipe, the rotating mechanism including a rotating rod rotatably connected inside the cavity, a cooling fan installed in the middle of the rotating rod, a rotating connector rotatably connected to the right side of the rotating rod, and a drive motor fixedly connected to the right side of the rotating connector.

[0006] As a further embodiment of this utility model, a water tank is installed on the left side of the bottom surface of the conveyor frame. The water tank has an internal cavity, and the inside of the cavity is fitted onto the outside of the water pump. The water tank serves to store cooling water.

[0007] As a further embodiment of this utility model, a chain conveyor belt is rotatably connected to the middle of the conveyor frame. The chain conveyor belt is made of high-temperature resistant metal material. The chain conveyor belt serves to withstand high temperatures and facilitate transportation.

[0008] As a further embodiment of this utility model, a feed inlet is provided on the lower left side of the water-cooled box, and a curtain is installed above the feed inlet. The curtain serves to prevent dust from entering.

[0009] As a further embodiment of this utility model, an air vent is provided in the middle of the left side of the water-cooled box, and two ventilation fans are installed on the top surface of the water-cooled box. The ventilation fans are designed to extract and disperse the internal hot air.

[0010] As a further embodiment of this utility model, the top surface of the air-cooled box is provided with a heat dissipation window, and a dustproof net is installed inside the heat dissipation window. The dustproof net serves to prevent dust from entering and reducing product quality while dissipating heat.

[0011] As a further embodiment of this utility model, a water outlet valve is fixedly connected to the lower right corner of the water tank, and the bottom of the water supply pipe extends through the middle right side of the water tank. The water outlet valve facilitates the emptying and cleaning of the water tank.

[0012] This invention provides a rapidly cooled forging for the heat treatment process, which has the following beneficial effects:

[0013] 1. In this heat treatment process, the forgings are rapidly cooled. Through the water-cooling mechanism, when the forgings need to be cooled after cold treatment, the outer forging is first placed on the left side of the conveyor belt. The conveyor belt carries the outer forging to the right. A water-cooling box is installed on the left side of the conveyor belt. Inside the water-cooling box are a water pump, water pipes, spray pipes, and booster nozzles. The water pump draws water from the water tank and transports it to the spray pipes through the water pipes. Finally, the water is evenly sprayed out from the booster nozzles at the bottom of the spray pipes. Because water cooling may generate a large amount of hot air and smoke, an exhaust window and a diffuser fan are installed on the top of the water-cooling box to expel the hot air, achieving a preliminary water-cooling effect. This avoids the slow cooling speed, reduced cooling efficiency, and decreased product qualification rate and production efficiency associated with single-stage water cooling.

[0014] 2. In this heat treatment process, the rapid cooling of forgings is achieved through a rotating mechanism. When the forgings need to be cooled after cold treatment, the initial water cooling of the external forgings may result in uneven cooling due to the single water cooling mode. Therefore, an air-cooled box is installed next to the water-cooled box, and a cooling fan is installed inside the air-cooled box. To adapt to the cooling of different external forgings, the blowing angle of the cooling fan needs to be adjusted. Therefore, rotating rods are installed on both sides of the cooling fan, with the outer sides of the rotating rods connected to the inner sides of the air-cooled box. To facilitate the rotation angle, the right side of the rotating rod... A rotating connector is installed, which is then connected to the drive motor on the right side. This allows the cooling fan to be adjusted at the desired angle, enabling water cooling followed by air cooling. This allows for controlled cooling, avoiding the difficulty in precisely controlling the cooling rate of water due to its strong cooling capacity. Air cooling after water cooling provides a relatively stable cooling transition phase after the forging undergoes rapid cooling, which helps to gradually release the thermal stress inside the forging, reducing the risk of deformation and cracking caused by thermal stress concentration, and improving the dimensional accuracy and quality stability of the forging.

[0022] Please see Figure 1 A water tank 6 is installed on the left side of the bottom of the conveyor frame 1. The water tank 6 has a cavity inside, and the inside of the cavity is fitted to the outside of the water pump 304. The water tank 6 serves to store the cooling water source.

[0023] Please see Figure 1 A chain conveyor belt 7 is rotatably connected to the middle of the conveyor frame 1. The chain conveyor belt 7 is made of high-temperature resistant metal material. The chain conveyor belt 7 serves to withstand high temperatures and facilitate transportation.

[0024] Please see Figure 2 A feed inlet is located on the lower left side of the water-cooled box 2. A curtain 8 is installed above the feed inlet to prevent dust from entering.

[0025] Please see Figure 2An air vent 9 is provided in the middle of the left side of the water-cooled box 2, and two ventilation fans 10 are installed on the top surface of the water-cooled box 2. The ventilation fans 10 are used to extract and dissipate the internal hot air.

[0026] Please see Figure 3 The top surface of the air-cooled box 4 is provided with a heat dissipation window, and a dustproof net 11 is installed inside the heat dissipation window. The dustproof net 11 serves to prevent dust from entering and reducing product quality while dissipating heat.

[0027] Please see Figure 1 A water outlet valve 12 is fixedly connected to the lower right corner of the water tank 6. The bottom of the water supply pipe 303 is connected to the middle right side of the water tank 6. The water outlet valve 12 facilitates the draining and cleaning of the water tank 6.

[0028] In this invention, the working steps of the device are as follows:

[0029] First step: First, place the outer forging on the left side of the conveyor frame 1 and the chain conveyor belt 7. The chain conveyor belt 7 carries the outer forging to the right. Since a water-cooled box 2 is installed on the left side of the conveyor frame 1, the water-cooled box 2 is equipped with a water pump 304, a water supply pipe 303, a water spray pipe 301, and a booster nozzle 302. The water pump 304 draws water from the water tank 6 and transports the water to the water spray pipe 301 through the water supply pipe 303. Finally, the water is evenly sprayed out from the booster nozzle 302 at the bottom of the water spray pipe 301. Since water cooling may generate a large amount of hot air and smoke, an exhaust window 9 and a diffuser fan 10 are installed on the top of the water-cooled box 2 to exhaust the hot air.

[0030] The second step: After the external forgings undergo preliminary water cooling, the single water cooling mode may cause uneven cooling. Therefore, an air-cooled box 4 is installed next to the water-cooled box 2. An air-cooled fan 502 is installed inside the air-cooled box 4. In order to adapt to the cooling of different external forgings, the blowing angle of the air-cooled fan 502 needs to be adjusted. Therefore, rotating rods 501 are installed on both sides of the air-cooled fan 502. The outer side of the rotating rods 501 is connected to the inner sides of the air-cooled box 4. In order to facilitate the rotation angle, a rotating connector 503 is installed on the right side of the rotating rods 501. The rotating connector 503 is then connected to the drive motor 504 on the right side, so that the air-cooled fan 502 can be adjusted at the required blowing angle.
