Description

Technical Field

[0001] This utility model relates to the field of wheel hub cooling technology, and more specifically to a cooling device for wheel hubs. Background Technology

[0002] After heat treatment, wheel hubs need to be properly cooled to avoid internal stress and deformation. There are certain requirements for the cooling method when cooling forged wheel hubs. Cooling too fast or too slow will cause quality problems in the subsequent finished products.

[0003] Currently, water mist cooling is commonly used to cool forged wheel hubs after forming. This cooling method can ensure the quality requirements of the finished product. However, currently, only the outer side of the wheel hub is cooled, which will lead to a temperature difference between the inside and outside, which will affect the product quality. Utility Model Content

[0004] The purpose of this invention is to solve the product quality problem caused by the temperature difference between the inside and outside of the forged wheel hub during water mist cooling. It provides a cooling device for wheel hubs that can cool both the inside and outside of the wheel hub simultaneously, thereby avoiding the problem of excessive temperature difference between the two sides leading to a decline in product performance.

[0005] To achieve the above objectives, this utility model provides a cooling device for a wheel hub, comprising:

[0006] A cooling tank, wherein the cooling tank is filled with coolant;

[0007] A base plate is fixedly installed on the top of the cooling box. A fan hole is provided in the center of the base plate, and several through holes are provided at intervals on the base plate.

[0008] A fan, wherein the fan is disposed inside the fan hole;

[0009] A circular conduit, disposed on the inner edge of the fan hole, wherein a plurality of internal nozzles are circumferentially spaced to spray a water mist-like coolant outwardly and obliquely upward along the radial direction of the conduit; and

[0010] The side plate is provided in two parts, which are respectively disposed on both sides of the base plate. The top of the side plate near the center of the base plate is provided with a number of external nozzles at intervals for spraying water mist coolant onto the center of the base plate.

[0011] Preferably, a water pump is also provided at the top of the cooling box.

[0012] Preferably, the upper end of the base plate is also provided with a slotted pipe, and an internal nozzle pipe is provided in the slotted pipe, which is connected to the water pump.

[0013] Preferably, the base plate further extends a support rod at the bottom end of the fan hole, the support rod is connected to a motor, and the output end of the motor is fixedly connected to the fan.

[0014] Preferably, a power supply is provided at the bottom of the side plate, and the power supply is connected to the motor via a wire.

[0015] Preferably, the wire is coated with an anti-corrosion coating.

[0016] Preferably, one side of the side plate is provided with an external nozzle pipe for connecting the water pump and the external nozzle.

[0017] The above technical solution utilizes a cooling box, base plate, fan, annular pipe, and side plate in combination. The heat-treated wheel hub is placed on the base plate, and internal and external nozzles simultaneously spray atomized coolant onto the wheel hub for synchronous cooling. At the same time, a fan installed in the fan hole blows the hot air from inside the wheel hub into the cooling box through the fan hole and through-hole, accelerating heat exchange within the cooling box. This achieves simultaneous cooling of the inside and outside of the wheel hub, while the fan accelerates gas circulation, preventing excessive accumulation of hot air that could reduce the cooling effect of the device. This solves the problem of excessive temperature difference between the two sides of the wheel hub during cooling, which can lead to a decrease in product performance. Attached Figure Description

[0025] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0026] like Figure 1-5 As shown, this utility model provides a cooling device for a wheel hub, including: a cooling box 1, a base plate 2, a fan 3, an annular pipe 4, and side plates 5. The cooling box 1 is filled with coolant. The base plate 2 is fixedly installed at the top of the cooling box 1. A fan hole 21 is provided at the center of the base plate 2. The base plate 2 is provided with several through holes 22 at intervals. The fan 3 is located inside the fan hole 21. The annular pipe 4 is located at the inner edge of the fan hole 21. Several internal nozzles 41 are arranged circumferentially at intervals on the annular pipe 4 for spraying water mist coolant outward and upward along the radial direction of the annular pipe 4. There are two side plates 5, which are respectively located on both sides of the base plate 2. Several external nozzles 51 are arranged at intervals on the top of the side plate 5 near the center of the base plate 2 for spraying water mist coolant towards the center of the base plate 2. Through the above technical solution, the heat-treated wheel hub is placed on the base plate 2 by the coordinated use of the cooling box 1, the base plate 2, the fan 3, the annular pipe 4, and the side plate 5. The internal nozzle 41 and the external nozzle 51 spray atomized coolant onto the wheel hub for synchronous cooling. At the same time, the fan 3, which is set in the fan hole 21, blows the hot air inside the wheel hub into the cooling box 1 through the fan hole 21 and the through hole 22, and accelerates the heat exchange in the cooling box 1. While achieving simultaneous cooling inside and outside the wheel hub, the fan 3 accelerates the gas circulation, avoiding the situation where too much hot air accumulates and the cooling effect of the device decreases. This solves the problem of product performance degradation caused by excessive temperature difference between the two sides of the wheel hub during cooling.

[0027] In some specific embodiments, the coolant used in the cooling tank 1 is water, which has a high specific heat capacity and is inexpensive.

[0028] According to the technical solution provided by this utility model, a water pump 11 is also provided at the top of the cooling box 1. This design allows the water flow rate of the internal nozzle 41 and the external nozzle 51 to be controlled.

[0029] Furthermore, a slotted pipe 23 is provided at the upper end of the base plate 2, and an internal nozzle pipe 411 is provided in the slotted pipe 23. The internal nozzle pipe 411 is connected to the water pump 11. This design is to prevent bulges from appearing on the surface of the base plate 2, making it easier to place the wheel hub into the device.

[0030] According to the technical solution provided by this utility model, the base plate 2 also extends a support rod 213 at the bottom end of the fan hole 21. The support rod 213 is connected to a motor 6. The output end of the motor 6 is fixedly connected to the fan 3. A power supply 7 is provided at the bottom of the side plate 5. The power supply 7 is connected to the motor 6 through a wire 67. The power supply 7 can supply power to the electrical components in this device. For example, in some embodiments, the water pump 11 can be set to electric and connected to the power supply. It is worth noting that the circuit connection method in this device will not be described in detail here, but it is necessary to ensure the wiring is safe and not prone to safety accidents.

[0031] In some embodiments, the conductor 67 is coated with an anti-corrosion coating. Although conventional conductors have a protective layer, this protective layer is easily corroded in high humidity environments, so it is necessary to apply a corresponding coating to prevent corrosion and avoid safety issues.

[0032] According to the technical solution provided by this utility model, an external nozzle pipe 511 is provided on one side of the side plate 5 for connecting the water pump 11 and the external nozzle 51. Here, the external nozzle pipe 511 near the water pump end is directly connected to the water pump 11, and the external nozzle pipe 511 away from the water pump 11 end is connected to the internal nozzle pipe 411 in the slot 23, thereby indirectly connecting to the water pump 11.
