Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy wheel hub manufacturing, in particular to a wheel hub cooling device. Background Art

[0002] The wheel hub needs to go through a coating process during the production process, where paint and powder are applied to cover the aluminum alloy surface to achieve the purpose of corrosion protection. During the coating process, the paint and powder sprayed on the surface of the wheel hub are cured into a film through high-temperature baking, and then the entire coating process is completed through a cooling step. When the wheel hub passes through the high-temperature baking area, the temperature can usually reach around 200°C. The cooling step requires the surface temperature of the wheel hub to be cooled from 200°C to around 50°C to meet the inspection requirements of the inspectors and the packaging requirements of the finished products. If the temperature is too high, the inspectors will be at risk of burns during the quality inspection process; at the same time, the finished wheel hubs with higher temperatures are prone to obvious indentations after packaging, which poses a quality risk.

[0003] At present, the production site uses air cooling to cool the wheels that have just come off the painting line. The air cooling effect is poor and time-consuming. It usually takes 30 minutes to cool down to the appropriate temperature, which restricts the production progress and causes a large consumption of cooling air sources, increasing production costs.

[0004] Based on this, developing a wheel hub cooling device for application in actual production is an issue that needs to be solved urgently. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] like Figure 1 As shown, a wheel hub cooling device includes a frame, and a water mist nozzle is arranged on the frame corresponding to the wheel hub of the coating offline line. The water mist nozzle is connected to the water source 33 and the wind source 34 through the water pipe 31 and the wind pipe 32 respectively, and the water mist nozzle is supplied with cooling water and high-pressure wind, so that the water mist nozzle can spray atomized water to cool the high-temperature wheel hub of the coating offline line. When in use, the frame is arranged near the channel of the wheel hub coating offline line, and the wind source 34 and the water source 33 are opened in sequence. The high-pressure wind is fully mixed with the cooling water in the water mist nozzle, and the cooling medium is sprayed in the form of water mist under the pressure of the high-pressure wind. When the high-temperature wheel hub is moving on the offline channel, the water mist nozzle on the frame will continue to spray atomized water on the high-temperature wheel hub, so that the high-temperature wheel hub is quickly cooled to a suitable temperature to meet the inspection requirements of the inspectors, avoid scalding the inspectors or delaying the inspection progress. At the same time, it meets the requirements for wheel hub packaging and eliminates the indentation problem caused by packaging the wheel hub at a high temperature.

[0023] This embodiment uses atomized water to cool the high-temperature wheel hub. Compared with the traditional air cooling method, this embodiment uses the larger specific heat capacity of atomized water to significantly improve the cooling efficiency of the wheel hub, reduce cooling time, save high-pressure wind consumption, and reduce production costs. At the same time, atomized water can cool the wheel hub at a relatively mild cooling rate compared to water cooling, avoiding the deformation of the wheel hub and paint film damage caused by the rapid cooling of the high-temperature wheel hub.

[0024] As a preferred embodiment, the water mist nozzle includes a side nozzle 21 arranged corresponding to the rim of the high-temperature hub, and may also include a top nozzle 22 arranged corresponding to the back cavity of the high-temperature hub. When in use, the side nozzle 21 and the top nozzle 22 work simultaneously, respectively spraying atomized water on the rim and back cavity of the high-temperature hub, so as to achieve the purpose of cooling the inside and outside of the hub at the same time, further improving the cooling efficiency.

[0025] Preferably, the frame includes a base 11, a support column is connected to the base 11, and a crossbeam 12 is connected to the top of the support column. The side nozzle 21 is connected to the support column, and the top nozzle 22 is connected to the crossbeam 12.

[0026] In order to improve the applicability of the utility model, the support column is a telescopic structure with adjustable height, so that the utility model can meet the cooling operation of wheel hubs with different rim heights. Specifically, the support column includes an outer sleeve 13 fixedly connected to the base 11, and a first lifting rod 14 is axially telescopically connected to the outer sleeve 13, and the side nozzle 21 is connected to the first lifting rod 14. The height of the side nozzle 21 can be adjusted by adjusting the length of the first lifting rod 14 extending out of the outer sleeve 13, which is convenient for cooling high-temperature wheel hubs with different rim heights.

[0027] Furthermore, a tightening screw 15 is provided on the outer sleeve 13, which is used to lock the position of the telescopic length of the first lifting rod 14. Specifically, the tightening screw 15 is threadedly connected to and passes through the side wall of the outer sleeve 13, and the front end of the tightening screw 15 is tightened on the first lifting rod 14 in the outer sleeve 13, so as to achieve the position locking of the first lifting rod 14.

[0028] Preferably, the top end of the first lifting rod 14 is telescopically connected to a second lifting rod 16 for adjusting the height of the overhead nozzle 22. The crossbeam 12 is horizontally connected to the second lifting rod 16. The height of the overhead nozzle 22 can be adjusted by adjusting the length of the second lifting rod 16 extending beyond the first lifting rod 14, thereby further improving the adjustment flexibility of the present invention.

[0029] Furthermore, the water pipe 31 and the air pipe 32 are both provided with regulating valves 35 for adjusting the supply of the water source 33 and the air source 34 to obtain atomized water of different strengths and concentrations to meet different cooling requirements.

[0030] The frame is provided with a fixer 17 for restraining the air duct 32 and the water pipe 31. The fixer 17 is respectively arranged on the support rod and the crossbeam 12, which restrains and fixes the scattered air duct 32 and the water pipe 31, improves the regularity of the device, and facilitates the maintenance of the device.
