An electric push rod drives the middle box to tilt outwards or inwards, facilitating adjustment of its position. This allows for adjustment of the top and middle boxes according to the processing needs of different materials. Furthermore, the two-in-one spray quenching structure of the top and middle boxes maximizes the adjustment range for hard and soft quenching, exceeding the operating range of a single quenching system. This effectively improves quenching efficiency and effect, thus solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable two-in-one spray quenching device, including a housing, wherein a quenching adjustment component for metal heat treatment is provided inside the housing;

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Refer to the instruction manual appendix Figure 1-5 This utility model provides an adjustable two-in-one spray quenching device, including a housing 1. The housing 1 is provided with a quenching adjustment component for metal heat treatment. The quenching adjustment component includes a top box 2, a middle box 3, and a bottom box 4 arranged sequentially from top to bottom inside the housing 1. The bottom of the top box 2 is equipped with multiple spaced flat nozzles 5. The middle box 3 and the bottom box 4 are each equipped with multiple spaced conical nozzles 6 on the side close to each other. The housing 1 is provided with a functional component for adjusting the center position. The functional component includes two support pillars 7 installed on the top of the middle box 3. Both support pillars 7 penetrate the housing 1 and extend to the outside of the housing 1. The ends of the two support pillars 7 away from the middle box 3 are equipped with the same support plate 8, and both ends of the support plate 8 are equipped with electric push rods 9 for connecting the housing 1.
[0026] When producing plates thicker than 25mm, water is sprayed onto the top of the plate through the flat nozzles 5 at the bottom of the top chamber 2. This is because thicker plates require higher water flow and density for sufficient cooling and quenching. At this time, the electric push rod 9 is activated to move the support plate 8 outwards. The support plate 8, via the support column 7, moves the middle chamber 3 outwards to a position flush with the top chamber 2, preventing the middle chamber 3 from interfering with the water spraying from the top chamber 2. When producing thin plates ≤25mm thick, water is sprayed onto the top of the thin plate through the conical nozzles 6 at the bottom of the middle chamber 3. This is because thin plates require lower water flow and density. At this time, the electric push rod 9 moves the support plate 8 inwards. The support plate 8, via the support column 7, moves the middle chamber 3 inwards to a position 200mm below the top chamber 2. This allows for spray adjustment according to the processing needs of different materials. The two-in-one spray quenching structure maximizes the adjustment range for hard and soft quenching, exceeding the operating range of a single quenching system, effectively improving quenching efficiency and effect.
[0027] When using the top chamber 2 for spraying during the quenching process described above, workers need to deliver water to the top chamber 2 and the bottom chamber 4. A water supply pipe 10 is located on the side of the shell 1 away from the support plate 8. A connecting pipe 11 is fixedly connected to the side of the water supply pipe 10 closest to the shell 1. A top pipe 12 and a bottom pipe 13 are fixedly connected to the top and bottom ends of the connecting pipe 11, respectively. The bottom ends of the top pipe 12 are fixedly connected to the top ends of the front and rear ends of the top chamber 2, respectively. The top ends of the bottom pipe 13 are fixedly connected to the bottom ends of the front and rear ends of the bottom chamber 4, respectively. First regulating valves 14 are installed on the exterior of both ends of the top pipe 12 and the bottom pipe 13. Furthermore, a first solenoid valve 19 is installed on the exterior of the end of the water supply pipe 10 closest to the connecting pipe 11, and a second solenoid valve 20 is installed on the exterior of the end of the diversion pipe 15 closest to the water supply pipe 10.
[0028] Before the workers deliver water, they need to open the first solenoid valve 19 and close the second solenoid valve 20. This allows water to be delivered to the top pipe 12 and the bottom pipe 13 via the connecting pipe 11. With the help of the first regulating valve 14, the flow rate in different areas of the top box 2 and the bottom box 4 can be adjusted independently, thereby regulating the water flow rate and spray pressure, reducing the generation of internal stress, and thus improving the quenching quality.
[0029] When using the middle box 3 for quenching, the workers need to supply water to the middle box 3 and the bottom box 4. Because the connecting pipe 11 has a diversion pipe 15 on the front side, the top end of the diversion pipe 15 is fixedly connected to the bottom of the water supply pipe 10, the bottom end of the diversion pipe 15 extends to the bottom of the shell 1, and the top of the diversion pipe 15 is fixedly connected to a branch pipe 16, the top end of the branch pipe 16 is fixedly connected to the bottom of the bottom box 4; the end of the diversion pipe 15 away from the water supply pipe 10 is fixedly connected to a hose 17, the end of the hose 17 away from the diversion pipe 15 extends to the top of the middle box 3, and the top end of the hose 17 is fixedly connected to the top of the middle box 3. A second regulating valve 18 is installed on the outside of the top end of the branch pipe 16 and the outside of the top end of the hose 17.
[0030] Before water is delivered to the middle tank 3 and the bottom tank 4, the first solenoid valve 19 needs to be closed and the second solenoid valve 20 needs to be opened. This allows the water supply pipe 10 to deliver water to the inside of the diversion pipe 15. The water in the diversion pipe 15 is then delivered to the inside of the bottom tank 4 and the middle tank 3 via the branch pipe 16 and the hose 17. This allows for spraying treatment by the conical nozzles 6 on the middle tank 3 and the bottom tank 4. At the same time, by setting the second regulating valve 18, the flow rate of different areas on the middle tank 3 and the bottom tank 4 can be independently adjusted, thereby achieving regulation of water flow rate and spraying pressure, reducing the generation of internal stress, and thus improving the quenching quality.
[0031] To ensure the stability of the middle box 3 during adjustment, an opening 21 is provided on the top of the housing 1 near the support plate 8. Both support columns 7 are located inside the opening 21. The opening 21 allows the middle box 3 to be adjusted inside and outside, thus ensuring the convenience of adjusting the middle box 3.
[0032] Furthermore, to facilitate the inspection and maintenance of the top pipe 12, bottom pipe 13, and branch pipe 16, through holes 22 are provided at both the top and bottom of the housing 1. The top pipe 12 is located inside the through hole 22 at the top of the housing 1, and the bottom pipe 13 and branch pipe 16 are located inside the through hole 22 at the bottom of the housing 1. This allows workers to inspect and maintain the top pipe 12, bottom pipe 13, and branch pipe 16 through the through holes 22, thus improving the convenience of inspection and maintenance of the top pipe 12, bottom pipe 13, and branch pipe 16.
[0033] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
