Description

Technical Field

[0001] This utility model relates to the field of forging technology, and in particular to a water circulation system for heat treatment of ring forgings and its production line. Background Art

[0002] In the aerospace industry, to achieve weight reduction, some ring forgings use aluminum alloys to replace the original materials in certain structures. Quenching is the most important heat treatment operation for aluminum alloys, and the most commonly used quenching medium is water. The quenching cooling rate is adjusted and the water temperature is controlled according to factors such as the material type, shape, size, and wall thickness of the aluminum alloy ring forging. Therefore, different aluminum alloy materials require different cooling water temperatures during quenching, which causes many inconveniences in production scheduling and planning. Furthermore, if the cooling water temperature exceeds the control temperature during production, the entire production line will be shut down.

[0003] Therefore, a technical solution is needed to address the problem that the required cooling water temperature is inconsistent during the quenching of aluminum alloy ring forgings, and that the temperature of the cooling water rises after use, making it unsuitable for cooling the next batch of workpieces. Utility Model Content

[0004] The purpose of this invention is to provide a heat treatment water circulation system and production line for ring forgings, which addresses the technical problem that the required cooling water temperature is inconsistent during the quenching of aluminum alloy ring forgings, and that the temperature of the cooling water rises after use, making it unsuitable for the cooling of the next batch of workpieces.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A water circulation system for heat treatment of annular forgings includes at least two water tanks and a cooling device. All the water tanks are connected to the cooling device via pipes, and each water tank is connected to the cooling device via a water pump and a control valve.

[0007] This utility model discloses a water circulation system for a ring forging heat treatment production line. In use, at least two water tanks are used, at least one for holding cold water and at least one for holding hot water at the required temperature (the temperature range of the hot water required for the quenching operation of aluminum alloy ring forgings in this application is 35℃-85℃). This system addresses the various quenching water temperature requirements of aluminum alloy ring forgings, catering to both hot and cold water quenching operations. The system also uses cooling equipment to cool the heated hot or cold water after quenching before returning it to the original water tank, ensuring that the water temperature in the tank fluctuates within a suitable range. This guarantees the continuity of the quenching operation and improves the efficiency of heat treatment production.

[0008] In a preferred embodiment of this utility model, the water tank is connected to a first inlet pipe and a first outlet pipe, and the cooling device is connected to a second inlet pipe and a second outlet pipe. All first inlet pipes are connected to the second outlet pipes, and all first outlet pipes are connected to the second inlet pipes. When the water temperature rises during quenching operations in the water tank, the heated water is led through the first outlet pipe to the second inlet pipe, and then enters the cooling device. After heat exchange in the cooling device, the water is returned to the water tank through the second outlet pipe, thus realizing the transfer of cooling water between the water tank and the cooling device.

[0009] As a preferred embodiment of this utility model, the water tank is equipped with a temperature monitoring component. This component allows for real-time monitoring of the water temperature within the tank, enabling staff to more accurately control the water temperature.

[0010] As a preferred embodiment of this utility model, it also includes a controller, wherein the control valve, water pump, and temperature monitoring component are electrically connected to the controller. The temperature monitoring component monitors the water temperature in the tank in real time. When the water temperature rises to a threshold, it transmits a signal to the controller, which then controls the corresponding valve and water pump to open, drawing the heated water into the cooling equipment. After heat exchange in the cooling equipment, the water is returned to the tank, thus achieving automated water temperature control.

[0011] As a preferred embodiment of this invention, the number of water tanks is two. Two water tanks, while satisfying both cold water quenching and hot water quenching requirements, represent the minimum number of tanks needed. This reduces interference from the water tanks with the quenching operation and also decreases equipment costs.

[0012] As a preferred embodiment of this utility model, at least one of the water tanks is provided with a heating element, which is electrically connected to the controller. By providing a heating element in a water tank, the cold water in the tank can be heated, which is convenient for heating the cold water to the required temperature when hot water is needed for quenching.

[0013] A ring forging heat treatment production line includes a track and a solution furnace mounted above the track. An operating vehicle capable of traveling along the track is provided on the track. The line also includes a ring forging heat treatment water circulation system as described above, wherein the water tank is slidably connected to the track.

[0014] This utility model discloses a heat treatment production line for ring forgings. In use, after the aluminum alloy ring forgings are solution-treated in a solution furnace, a water tank that is slidably connected to the track is pulled to the bottom of the solution furnace by an operating trolley. Then, the rack carrying the ring forgings is placed into the water tank for quenching. In this application, two or more water tanks are set up, one for holding hot water and the other for cooling, to facilitate quenching of aluminum alloy ring forgings with different temperature requirements. At the same time, the water temperature in the water tank is controlled by the cooling equipment to achieve the purpose of recycling the quenching water, so that the quenching operation can be continuous and the heat treatment efficiency can be improved.

[0015] In a preferred embodiment of this invention, all the water tanks are located on both sides of the solution furnace. After the annular forging is solution-treated, a suitable water tank can be selected according to the required cooling temperature of the annular forging. The operating vehicle pulls the corresponding water tank to the bottom of the solution furnace to facilitate the cooling and lowering of the annular forging and reduce the mutual interference between the water tanks.

[0016] As a preferred embodiment of this utility model, a first flexible hose connects the first inlet pipe and the second outlet pipe, and a second flexible hose connects the first outlet pipe and the second inlet pipe. The water tank and the cooling equipment are connected via the first and second flexible hoses, preventing the water tank from dragging the cooling equipment or pipes as it travels along the track, thus protecting the equipment.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] 1. This application sets up two or more water tanks for cold water quenching and hot water quenching respectively, which meets the various requirements of aluminum alloy ring forgings for quenching temperature.

[0019] 2. The hot or cold water that has been heated after quenching is cooled down by a cooling device and then transported back to the original water tank so that the water temperature in the tank fluctuates within a suitable range, thereby ensuring the continuity of the quenching operation and improving the efficiency of heat treatment production.

Detailed Implementation

[0024] The present invention will now be described in detail with reference to the accompanying drawings.

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] Example 1

[0027] like Figure 1 As shown in the figure, this embodiment of a ring forging heat treatment water circulation system includes at least two water tanks 1, each with a volume of 75m³, which can ensure that the water temperature fluctuation during the quenching process of the water tank 1 is ≤10℃. During the production process, the water in the water tank 1 is stirred in real time throughout the entire process. It also includes a cooling device 2, model: LSQWRF130M / AN1-W, which is equipped with heat exchange plates. All the water tanks 1 are connected to the cooling device 2 by pipes. Each water tank 1 is connected to the cooling device 2 by a water pump 3 and a control valve 4.

[0028] In use, at least one of the two water tanks 1 is used to hold cold water and at least one is used to hold hot water at the required temperature (the temperature range of the hot water required for the quenching operation of aluminum alloy ring forgings in this application is 35℃-85℃). This addresses the various quenching water temperature requirements of aluminum alloy ring forgings that require hot water and cold water respectively. The hot or cold water that has been heated after quenching is cooled by the cooling equipment 2 and then transported back to the original water tank 1 so that the water temperature in the water tank 1 fluctuates within a suitable range, thereby ensuring the continuity of the quenching operation and improving the efficiency of heat treatment production.

[0029] Specifically, the water tank 1 is connected to a first inlet pipe 11 and a first outlet pipe 12, and the cooling device 2 is connected to a second inlet pipe 21 and a second outlet pipe 22. The second inlet pipe 21 is connected to a main inlet pipe, and the first outlet pipe 12 is connected to an outlet pipe. Each outlet pipe is connected to the main inlet pipe. A water pump 3 is installed on the main inlet pipe, and a control valve 4 is installed on the outlet pipe. The second outlet pipe 22 is connected to the main outlet pipe, and the first inlet pipe 11 is connected to a branch inlet pipe. Each branch inlet pipe is connected to the main outlet pipe. A water pump 3 is installed on the main outlet pipe, and a control valve 4 is installed on the branch inlet pipe. When the water temperature rises during the quenching operation in the water tank 1, the heated water is led to the second inlet pipe 21 through the first outlet pipe 12, and then enters the cooling device 2. After heat exchange in the cooling device 2, the water is transported back to the water tank 1 through the second outlet pipe 22, thus realizing the transfer of cooling water between the water tank 1 and the cooling device 2.

[0030] Furthermore, there are two water tanks 1. Under the premise of satisfying both cold water quenching and hot water quenching, the two water tanks 1 have the minimum number of water tanks 1. This can reduce the interference of water tanks 1 on the quenching operation and reduce equipment cost investment.

[0031] Example 2

[0032] like Figure 1 and Figure 2 As shown, the difference between this embodiment and embodiment 1 is that the water tank 1 is equipped with a temperature monitoring component 13. The temperature monitoring component 13 includes three thermocouples, namely a control thermocouple, an over-temperature thermocouple, and a coldest point thermocouple, which monitor the water temperature in real time and feed it back to the control center.

[0033] In this embodiment, the temperature monitoring group 13 monitors the water temperature in the water tank 1 in real time, so that the staff can more accurately control the water temperature in the water tank 1.

[0034] Furthermore, at least one of the water tanks 1 is provided with a heating element 14, which is electrically connected to the controller 5. By providing a heating element in a water tank 1, the heating element 14 can be a heating device such as an electric heating wire or an electric heating plate. The heating element 14 can heat the cold water in the water tank 1, so that when hot water is needed for quenching, the cold water can be heated to the required temperature by the heating element 14.

[0035] Furthermore, it also includes a controller 5, model CM40. The control valve 4, water pump 3, temperature monitoring component 13 and heating element 14 are electrically connected to the controller 5. The temperature monitoring component 13 monitors the water temperature in the water tank 1 in real time. When the water temperature rises to the threshold, it transmits a signal to the controller 5. The controller 5 controls the corresponding control valve 4 and water pump 3 to open, pumping the heated water into the cooling device 2. After heat exchange in the cooling device 2, the water is sent back to the water tank 1, thus realizing the automatic control of water temperature.

[0036] Example 3

[0037] like Figure 1 and Figure 3 As shown, this embodiment provides a ring forging heat treatment production line, including a track 8 and a solution furnace 9 mounted on the track 8. The track 8 is equipped with an operating vehicle 10 that can travel along the track 8. It also includes a ring forging heat treatment water circulation system as described in Embodiment 1 or Embodiment 2. The water tank 1 is slidably connected to the track 8.

[0038] In use, after the aluminum alloy ring forging is dissolved in the solution furnace 9, the water tank 1, which is slidably connected to the track 8, is pulled to the bottom of the solution furnace by the operating vehicle 10. Then, the rack carrying the ring forging is placed into the water tank 1 for quenching. In this application, two or more water tanks 1 are set up to hold hot water and cool it, respectively, so as to facilitate the quenching treatment of aluminum alloy ring forgings with different temperature requirements. At the same time, the water temperature in the water tank 1 is controlled by the cooling equipment 2 to achieve the purpose of quenching water circulation, so that the quenching operation can be continuous and the heat treatment efficiency can be improved.

[0039] Furthermore, all the water tanks 1 are located on both sides of the solution furnace 9. After the ring forging is solution treated, a suitable water tank 1 can be selected according to the required cooling temperature of the ring forging. The operating vehicle 10 pulls the corresponding water tank 1 to the bottom of the solution furnace to facilitate the cooling and reduction of the ring forging and reduce the mutual interference between the water tanks 1.

[0040] Furthermore, a first flexible hose 6 is connected between the first water inlet pipe 11 and the second water outlet pipe 22, and a second flexible hose 7 is connected between the first water outlet pipe 12 and the second water inlet pipe 21. The water tank 1 and the cooling equipment 2 are connected through the first flexible hose 6 and the second flexible hose 7, so as to prevent the cooling equipment 2 or the pipeline from being dragged when the water tank 1 moves along the track 8, thus protecting the equipment.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
