Description

Technical Field

[0001] This utility model relates to the field of metal heat treatment, and more specifically, it relates to a metal quenching device for metal heat treatment. Background Technology

[0002] Quenching is a heat treatment process. For steel, quenching involves heating the steel to a temperature above the critical temperature (for hypoeutectoid or hypereutectoid steel), holding it at that temperature for a period to achieve complete or partial austenitization, and then rapidly cooling it at a rate greater than the critical cooling rate to below Ms (or isothermally near Ms) to induce martensitic (or bainitic) transformation. This process is widely used in the production of metal products. Quenching equipment is generally used to achieve the quenching purpose. However, different types of metals require different quenching solutions; some require water quenching, while others require oil quenching. Existing quenching equipment is inconvenient for changing the quenching solution, thus affecting its applicability to different metals. Furthermore, larger metal products need to be immersed in the quenching solution during quenching. When the metal product is small or sheet-like, it may float on the surface, preventing one surface from contacting the quenching solution and hindering the quenching process. Utility Model Content

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a metal quenching device for metal heat treatment, which has the following beneficial effects:

[0017] 1. This utility model, by setting up a processing tank, a water tank, and a storage tank, allows for the following process when heat-treating metal products: If the metal products require oil quenching, according to existing technology, a pump body is placed in the storage tank. The pump body in the storage tank pumps the oil into the processing tank through a third connecting pipe. The metal products are then placed on a support frame, and an electric push rod extends to move the support frame into the processing tank, immersing it in the oil, thus achieving oil quenching of the metal products. If water quenching is required, the water tank is connected to an external water supply device through the water inlet pipe at the top, adding water to the tank. A second pump body draws water from the tank and pumps it into a movable frame through a connecting pipe. The movable frame is connected to a nozzle, allowing water to be sprayed from the nozzle into the processing tank, quenching the metal products with water. This facilitates the replacement of the quenching liquid as needed, making it convenient to quench different metal products.

[0018] 2. This utility model, by setting up a spray structure, allows water to be drawn from the water tank by a second pump body when the metal parts to be quenched float on the water surface. The water is then pumped into the moving frame through a connecting pipe. The moving frame is connected to the nozzle, allowing water to be sprayed from the nozzle onto the surface of the metal parts. The other side of the metal parts comes into contact with the water surface in the treatment tank, thus facilitating the quenching of all surfaces of smaller metal parts and making the entire quenching equipment easier to use.

[0019] 3. This utility model connects the processing tank and the water tank via an intermediate pipe, which is connected by a first connecting pipe and a second connecting pipe. After a metal product is quenched, the oil absorbs heat from the metal product, causing the oil to heat up. The oil is then pumped from the processing tank into the intermediate pipe through the first connecting pipe by the first pump body. Once the oil reaches the intermediate pipe, the heat is conducted to the water in the water tank through the heat sink, thus cooling the oil. The cooled oil then returns to the processing tank through the second connecting pipe, which helps maintain a lower oil temperature and facilitates continuous quenching of metal products.

[0030] A spray structure is provided on the support plate 3. The spray structure includes a movable frame 7, a nozzle 8, a threaded rod 9 and a sliding rod 10. The movable frame 7 is movably mounted on the support plate 3. An electric push rod 11 is fixedly mounted on the support plate 3.

[0034] Specifically, if the metal product needs to be quenched with oil, the external pump in the storage tank 6 pumps the oil into the processing tank 1 through the third connecting pipe 21. The metal product is placed on the support frame 12, and the electric push rod 11 extends to drive the support frame 12 into the processing tank 1 and immerse it in the oil, thereby realizing the oil quenching of the metal product. During the quenching process, the oil absorbs heat from the metal product, causing the oil temperature to rise. The first pump 20 pumps the oil from the processing tank 1 into the intermediate pipe 15 through the first connecting pipe 18. After the oil reaches the intermediate pipe 15, the heat is conducted to the water in the water tank 4 through the heat sink 16, thereby cooling the oil with water. The cooled oil returns to the processing tank 1 through the second connecting pipe 19, keeping the oil at a low temperature and realizing continuous quenching of the metal product.

[0035] Please refer to Figure 1-5As an embodiment of quenching metal products by water: The support plate 3 has mounting grooves 22 at both ends, and threaded rods 9 and sliding rods 10 are respectively installed in the two mounting grooves 22.

[0036] Specifically, if water is needed to quench metal products, the water supply device is connected to the water inlet pipe 14 at the top of the water tank 4 to add water to the water tank 4. The water in the water tank 4 is drawn by the second pump body 25 and pumped into the moving frame 7 through the connecting pipe 26. The water is sprayed out from the nozzle 8 through the connection between the moving frame 7 and the nozzle 8 and sprayed into the treatment box 1 to quench the metal products.

[0037] In summary, when using it as a whole:

The metal products are placed on the support frame 12, and the electric push rod 11 extends to drive the support frame 12 into the processing tank 1, where it is immersed in the oil, thus achieving oil quenching of the metal products. During the quenching process, the oil absorbs heat from the metal products, causing the oil temperature to rise. The first pump 20 pumps the oil from the processing tank 1 into the intermediate pipe 15 through the first connecting pipe 18. After the oil reaches the intermediate pipe 15, the heat is conducted to the water in the water tank 4 through the heat sink 16, thereby cooling the oil with water. The cooled oil returns to the processing tank 1 through the second connecting pipe 19, keeping the oil at a low temperature and achieving continuous quenching of the metal products.

[0039] When metal products need to be quenched with water, the water supply device is connected to the water tank 4 through the water inlet pipe 14 at the top of the water tank 4, water is added to the water tank 4, the second pump body 25 draws water from the water tank 4, and pumps it into the moving frame 7 through the connecting pipe 26. The moving frame 7 is connected to the nozzle 8, so that the water is sprayed out from the nozzle 8 and sprayed into the treatment box 1, and the metal products are quenched by water.
