Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment cooling equipment, in particular to a cooling device for forging heat treatment. Background Technique

[0002] In the forging process, the cooling step after heat treatment of forgings usually adopts treatment methods such as furnace cooling, air cooling, oil cooling and water cooling, and the cooling methods are divided into isothermal cooling and continuous cooling. For different types of forgings, different treatment methods and cooling methods can be selected, and the temperature of the cooling medium can be adjusted according to the forging material to control the cooling time of the forgings, so that the cooled forgings have better product performance.

[0003] The oil cooling method for forgings can enable the forgings to obtain a certain hardness and qualified metallographic structure. Therefore, the oil cooling treatment method is most suitable for many forgings. However, some existing oil cooling devices for forging heat treatment use an oil pool to carry the cooling oil. When the number of forgings to be cooled is large, the oil temperature will rise, resulting in an unqualified cooling speed, which will in turn affect the product performance of the forgings. Therefore, a cooling device for forging heat treatment is proposed for the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a cooling device for forging heat treatment to solve the problem that some existing oil cooling devices for forging heat treatment use an oil pool to carry the cooling oil. When the number of forgings to be cooled is large, the oil temperature will rise, resulting in an unqualified cooling speed, which will in turn affect the product performance of the forgings.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0023] Please refer to Figure 1-6 , the present utility model provides a technical solution:

[0024] A cooling device for forging heat treatment, comprising a cooling pool 1 and a circulating water pool 2. The bottom of the cooling pool 1 is fixedly connected to a first support frame 3, and the bottom of the circulating water pool 2 is fixedly connected to a second support frame 4. The left sides of the cooling pool 1 and the circulating water pool 2 are respectively fixedly connected to the relative outer ends of two first water pipes 5. The relative inner ends of the two first water pipes 5 are respectively fixedly connected to the front and rear ends of a water pump 6. The left end of the water pump 6 is fixedly connected to a controller 7, and the bottom of the water pump 6 is fixedly connected to a third support frame 8. The right ends of the cooling pool 1 and the circulating water pool 2 are respectively fixedly connected to the two ends of a second water pipe 9. A cooling oil tank 10 is fixedly connected inside the cooling pool 1. An electric control switch valve 11 is fixedly connected to the bottom of the cooling pool 1. The bottom of the electric control switch valve 11 is fixedly connected to an oil drain pipe 12. A heat exchange tank 13 is arranged between the cooling pool 1 and the cooling oil tank 10. A first partition plate 14 and a second partition plate 15 are fixedly connected between the cooling pool 1 and the cooling oil tank 10.

[0025] Both the cooling pool 1 and the circulating water pool 2 are rectangular pools. The first support frame 3, the second support frame 4 and the third support frame 8 are all composed of a rectangular fixed frame and a vertical support shaft. The four corners of the bottom of the rectangular fixed frames of the first support frame 3, the second support frame 4 and the third support frame 8 are respectively fixedly connected to the vertical support shafts, which can fix the cooling pool 1, the circulating water pool 2 and the water pump 6. There are two first water pipes 5, and the first water pipes 5 are both bent rectangular pipes. The two first water pipes 5 are symmetrically distributed front and back. The controller 7 is electrically connected to the water pump 6 and the electric control switch valve 11 respectively. The second water pipe 9 is a bent rectangular pipe, which can connect the cooling pool 1 and the circulating water pool 2. There are multiple cooling oil tanks 10, and the cooling oil tanks 10 are evenly distributed at equal distances. The cooling oil tanks 10 are all rectangular boxes with open tops. Cylindrical oil drain grooves are arranged at the bottoms of the cooling oil tanks 10. Multiple cylindrical oil drain grooves are arranged at equal distances at the bottom of the cooling pool 1, which can discharge the cooling oil more conveniently. There are multiple electric control switch valves 11 and oil drain pipes 12. The first partition plate 14 and the second partition plate 15 are both vertically distributed rectangular plates. The first partition plate 14 is distributed in the up and down direction in the top view, and the second partition plate 15 is distributed in the left and right direction in the top view. The first partition plate 14 and the second partition plate 15 can divide the heat exchange tank 13 into a bent water channel.

[0026] Workflow: Before use, connect the power supply. At this time, the electric control switch valves 11 are all closed. Inject an appropriate amount of cooling water into the circulation water tank 2 and add an appropriate amount of cooling oil into each cooling oil tank 10. Then the device can be used normally. Place the forging to be cooled in the cooling oil of the cooling oil tank 10 and perform rapid cooling through the cooling oil. When a large number of forgings need to be cooled in a short time, the device works continuously and the cooling oil will heat up. At this time, adjust the water pump 6 to start through the controller 7. The water pump 6 can input the cooling water in the circulation water tank 2 into the heat exchange tank 13. Due to the separation of the first partition plate 14 and the second partition plate 15, the heat exchange tank 13 becomes a bent water channel. The cooling water enters the heat exchange tank 13 from the lower left corner of the cooling pool 1 and flows through the water channel separated by the first partition plate 14 and the second partition plate 15, and finally returns to the circulation water tank 2 from the lower right corner of the cooling pool 1. It can exchange heat with the cooling oil in the cooling oil tank 10 and quickly take away the heat. The cooling water after heat exchange circulates into the circulation water tank 2. The top of the circulation water tank 2 is open, which can dissipate heat quickly and greatly improve the cooling performance of the device. After the device is used for a period of time, the electric control switch valve 11 can be adjusted to open through the controller 7, and the cooling oil can be discharged through the oil drain pipe 12, which is convenient for replacing the cooling oil. The device can quickly cool down the cooling oil when there are a large number of forgings to be cooled, ensure the cooling effect and cooling speed of the cooling oil, and avoid affecting the product performance of the forging.
