[0002] In the manufacturing of modern automobile parts, some special-shaped structural parts are often processed by casting and other methods for rapid manufacturing. Under high temperature, the parts will produce residual stress and grain coarsening inside, which will affect the performance and stability of the parts, so quenching treatment is required.

[0003] At present, quenching furnaces are usually used for quenching automobile parts. The workpiece needs to be cooled rapidly between the quenching and tempering processes. The current cooling method is mostly through water cooling. In the quenching treatment device, such as an immersion cooling device disclosed in patent publication number CN214612637U, the steam generated by cooling is recovered.

The initial amount of steam generated is large. While driving the impeller, a large part of the steam is directly discharged due to the large amount of steam, resulting in waste. In view of this, in-depth research was conducted on the above-mentioned problems, and this case was generated. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0019] See also Figure 1-3 The utility model provides an implementation scheme: when hot stamping automobile parts, it is necessary to perform quenching treatment on the automobile parts. The role of quenching treatment is to quickly cool the metal material so that the parts can obtain higher hardness and strength. Quenching can effectively eliminate the residual stress inside the parts, refine the grains, and improve the hardness and strength of the metal. The public document CN214612637U designs a quenching device for hot stamping automobile parts. The steam generated by the contact between the high-temperature parts and the cooling water drives the impeller of the generator to rotate. However, the steam generated in this way is relatively short-lived and unstable, especially in the front stage of quenching, the steam volume is large, which easily leads to a lot of steam being discharged before it can push the impeller of the generator, so the steam is wasted;

[0020] Based on the above reasons, the present application discloses a quenching device for hot stamping automobile parts, the main body of the device is a cooling shell 1, the cooling shell 1 is a rectangular cavity container, a cooling water replenishing system 2 is arranged at the bottom of the cooling shell 1, and cooling water is replenished in the cooling shell 1 through the cooling water replenishing system 2, and the cooling shell 1 is divided into two parts, a circulating feeding mechanism 3 is arranged at the upper part, and an immersion cooling tank 4 is arranged at the lower part of the cooling shell 1, the circulating feeding mechanism 3 can be used to step-by-step convey the material, and the immersion cooling tank 4 is loaded with coolant to quench the automobile parts passing through;

[0021] According to the instruction manual Figure 1-3 It can be seen that the top of the cooling housing 1 is also connected with a conduit 5, one end of which is connected to a condensation exhaust container 6, and an impeller generator 7 is provided on the condensation exhaust container 6. The nozzle of the conduit 5 corresponds to the impeller of the impeller generator 7, and the generated steam is directed to one side of the condensation exhaust container 6 through the conduit 5. The impeller generator 7 on the condensation exhaust container 6 corresponds to the nozzle of the conduit 5, and the impeller is driven to rotate when the steam is discharged, so that the generator generates electricity, and the steam generated by quenching is effectively utilized;

[0022] According to the instruction manual Figure 1-3It can be seen that the above-mentioned circulating feeding mechanism 3 includes a continuous conveyor belt 301, which is located in the cooling housing 1 and is provided with a downward U-shaped bend 302, and the lowest point of the "J"-shaped bend passes through the immersion cooling tank 4. The circulating feeding mechanism 3 also includes a material tray 303, and the material tray 303 is provided with at least 5 groups;

[0023] In the specific implementation process, the continuous conveyor belt 301 adopts a roller conveying structure, and the power of the roller conveying structure comes from a stepper motor. At least 5 groups of material trays 303 are arranged on the continuous conveyor belt 301, and hot-pressed automobile parts are placed on the material trays 303. The continuous conveyor belt 301 is provided with a U-shaped bend 302 section in the cooling shell 1, so that the continuous conveyor belt 301 passes through the immersion cooling tank 4 in the process of passing through the cooling shell 1. In order to ensure the uniformity of the steam amount, the interval between the material trays 303 on the continuous conveyor belt 301 is set to be smaller than the length of the U-shaped bend, so that the parts of the quenching second half in the previous material tray 303 and the material tray 303 that has just entered the immersion cooling tank 4 compensate each other during quenching, so that the steam can be continuously and more stably passed into the conduit 5. At the same time, the quenching process is gradual, which can effectively control the evaporation of steam.

[0024] As a preferred embodiment, further, the circulating feeding mechanism 3 also includes a material inlet 304 and a material outlet 305, and the material inlet 304 and the material outlet 305 are respectively installed on the two side walls of the cooling casing 1, and the material inlet 304 and the material outlet 305 are provided with a rolling closed door 306. In the specific implementation process, the continuous conveyor belt 301 passes through the material inlet 304 and the material outlet 305. When the continuous conveyor belt 301 drives the material through the cooling casing 1, the material inlet 304 and the material outlet 305 are closed as a closing device, so that the steam will not escape from the material inlet 304 and the material outlet 305. Further, the steam can be guided by setting a fan with a guiding function at the tail end of the conduit 5.

[0025] As a preferred solution, further, the rolling closed door 306 and the material inlet 304 or the material outlet 305 are sealed with a one-way sealing limit structure. The one-way sealing limit structure is specifically a bevel sealing device on the rolling closed door 306 and the material inlet 304 and the material outlet 305. The bevel of the rolling closed door 306 is fitted with the bevel of the material inlet 304 or the material outlet 305, so as to achieve a one-way sealing effect, and a torsion spring is arranged on the rolling closed door 306. When the continuous conveyor belt 301 drives the material tray 303 to pass through the rolling closed door 306, the rolling closed door 306 is pushed open, and when the material tray 303 passes through the material inlet 304 or the material outlet 305, the material inlet 304 or the material outlet 305 is closed by the rebound effect of the torsion spring.

[0026] As a preferred solution, further, a cooling drain pipe 8 extends from the bottom of the condensation exhaust container 6, and a collecting tank 9 is placed below the cooling drain pipe 8. After the condensation exhaust container 6 completes driving the impeller engine, the condensed water after work is diverted from the condensation drain pipe and drips into the collecting tank 9.

[0027] As a preferred solution, further, a battery 10 is connected to one side of the impeller generator 7 for storing electricity.

[0028] As a preferred solution, further, according to the attached description Figure 1-3 It can be seen that the cooling water supply system 2 at least includes a liquid level detector 201, a water supply pump 202 and a water supply pipe 203. The liquid level detector 201 is installed in the immersion cooling tank 4. One side of the immersion cooling tank 4 is connected to the water supply pipe 203, and the water supply pump 202 is provided on the water supply pipe 203.

[0029] During the specific implementation process, the water level in the immersion cooling tank 4 is detected by the liquid level detector 201. When it is detected that the water level in the immersion cooling tank 4 is lower than the immersion material tank, the immersion cooling tank 4 is replenished with water through the water replenishment pipe 203 connected to the outside. The main control circuit of the liquid level detector 201 is connected to the water replenishment pump 202, and the water replenishment is controlled by the switch of the water replenishment pump 202.

[0030] From the above, it can be generally known that the quenching device for hot stamping automobile parts uses the steam generated by the contact between high-temperature parts and cooling water during the quenching process as the power for generating electricity. In order to ensure the continuity of steam generation, a circulating conveying mechanism is provided to carry the stamping parts through the immersion cooling pool in batches according to the set distance, so that the steam generation is more stable and controllable, thereby making the power generation process more stable. In addition, since a circulating conveying mechanism is provided, loading and unloading stations can be set outside the cooling casing 1, which is more convenient for loading and unloading.

[0031] 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.
