[0003] During the water quenching cooling process of the casting, the equipment will place the wheel hub casting that has just been formed from the mold into water at 60-80 degrees Celsius for cooling. In this process, due to the high temperature of the wheel hub casting, it will cause the surrounding water to boil, and water vaporization will occur on the surface of the wheel hub to form air pockets, which will significantly affect the cooling rate and cause the mechanical properties of the corresponding position of the wheel hub to decrease.

The water quenching cooling process of the present invention adopts a fixed water spray pipe and a movable water spray pipe to spray water. The wheel hub is clamped by a wheel hub clamp and a bracket and moves up and down quickly at the water spray port of the fixed water spray pipe, which avoids the formation of air bags on the surface of the wheel hub and accelerates the flow of water, so that the surface of the wheel hub can be quickly cooled.

Figure 3 and Figure 4 , the water quenching cooling equipment for casting wheel hub of the present invention is described.

[0077] like Figure 3 and Figure 4 As shown, the water quenching cooling device for casting wheel hub of the present invention comprises a water tank 21, a fixed water spray pipe 22, a bracket 23, a movable water spray pipe 24, a wheel hub fixture 25 and an exhaust port 212; an opening 211 is provided on the top of the water tank 21, and the interior of the water tank 21 is enclosed to form a closed space; Figure 5 As shown, the fixed water spray pipe 22 is arranged inside the water tank 21, and a plurality of water spray ports 223 are arranged on the fixed water spray pipe 22; Figure 7 and Figure 8 As shown, the bracket 23 is arranged in the water tank 21 and can be raised and lowered. The bracket 23 is provided with a rotatable rotating disk 231, and the rotating disk 231 is supported with a plurality of rotatable supporting rollers 232; the movable water spraying pipe 24 is connected to the bracket 23 and can be raised and lowered together with the bracket 23. The movable water spraying pipe 24 passes through the rotating disk 231 and is connected to a high-pressure nozzle 241; Figures 9 to 11As shown, the hub clamp 25 can be moved and adjusted along the vertical direction. The hub clamp 25 is arranged beside the water tank 21. The hub clamp 25 is provided with a pair of clamping jaws 251 with adjustable clamping spacing. A rotatable limiting roller 252 is provided on each clamping jaw 251 corresponding to the top of the clamped hub 10; the exhaust port 212 is provided at the opening 211 of the water tank 21; preferably, the exhaust port 212 is provided around the opening 211; when the hub 10 is water quenched, The wheel hub clamp 25 clamps the corresponding wheel hub 10 and moves downward in the vertical direction, so that the wheel hub 10 enters the water tank 21 from the opening 211 and is then placed on the supporting roller 232. The wheel hub clamp 25 and the bracket 23 move up and down synchronously, so that the wheel hub 10 moves up and down through the water spray port 223 of the fixed water spray pipe 22, and the water spray port 223 of the fixed water spray pipe 22 and the high-pressure nozzle 241 of the movable water spray pipe 24 spray cold water to cool the wheel hub 10.

After the bracket 23 supports the wheel hub 10, the supporting rollers 232 on the bracket 23 and the limiting rollers 252 on the wheel hub clamp 25 clamp the wheel hub 10 up and down, and then the bracket 23 and the wheel hub clamp 25 are moved downward synchronously, and the wheel hub 10 moves downward through the water spray port 223 of the fixed water spray pipe 22. In this way, the cold water sprayed from the water spray port 223 can cool the periphery of the wheel hub 10, and the bracket 23 and the wheel hub clamp 25 can move up and down quickly, which can avoid the formation of water vaporization on the surface of the wheel hub 10 to produce air bags, thereby solving the problem of the formation of air bags affecting the cooling rate and causing the reduction of mechanical properties. The high-pressure nozzle 241 of the mobile water spray pipe 24 has a plurality of nozzles inclined upwardly. When the wheel hub 10 is placed on the supporting roller 232, each nozzle can be aligned with the bottom surface of the wheel hub 10.

In this way, when entering the water tank for cooling, the wheel hub bead seat and the spoke set downward can first contact with water for cooling, and the thickness of the wheel hub bead seat and the spoke is greater than the inner wheel rim of the wheel hub, so that the wheel hub surface can be cooled evenly, the efficiency of water quenching cooling is improved, and the mechanical properties of the wheel hub casting are improved. If the inner wheel rim of the thinner wheel hub contacts water for cooling first, its cooling speed will be faster than that of the thicker wheel hub bead seat and the spoke, and different cooling rates will affect the strength of the wheel hub.

[0114] The working process of the water quenching cooling device for casting wheel hub of the present invention is described below.

[0115] like Figure 1 and Figure 2 As shown, after the wheel hub is cast, the wheel hub clamping mechanism 33 clamps the wheel hub 10 and flips the wheel hub 10 180° so that the wheel hub bead seat and the spokes on the wheel hub 10 can be set downward, and then the wheel hub 10 is placed on the wheel hub conveying mechanism 31.

[0116] The wheel hub conveying mechanism 31 conveys the wheel hub 10 until it contacts the baffle 311, and then the detection switch 32 moves upward in the vertical direction until the upper surface of the wheel hub 10 is detected. The wheel hub clamp 25 moves to the top of the wheel hub 10 through the horizontal sliding mechanism 261, and then moves downward through the vertical sliding mechanism 262 until the detection switch 32 detects the limiting roller 252 of the wheel hub clamp 25. At this time, the limiting roller 252 just contacts the upper surface of the wheel hub 10, stops the downward movement of the wheel hub clamp 25, and uses the wheel hub clamp 25 to clamp the wheel hub 10.

[0117] Then the vertical sliding mechanism 262 moves upward for adjustment, and the horizontal sliding mechanism 261 moves the wheel hub clamp 25 and the wheel hub 10 thereon to the top of the water tank 21, and the vertical sliding mechanism 262 moves downward for adjustment again to place the wheel hub 10 on the supporting roller 232, and the top and bottom of the wheel hub 10 are clamped by the limiting roller 252 and the supporting roller 232. The wheel hub clamp 25, the limiting roller 252 and the supporting roller 232 can adapt to different models of wheel hubs 10.

[0118] The vertical lifting drive 274 drives the bracket 23 to move up and down through the chain 273. At the same time, the hub clamp 25 also moves up and down synchronously under the drive of the vertical sliding structure 262, so that the hub 10 can move up and down quickly in the water tank 21. The roller 2512 on the hub clamp 25 can prevent the hub 10 from moving up and down during the up and down movement.

[0119] While the bracket 23 and the wheel hub clamp 25 move up and down, cold water is provided to the fixed water spray pipe 22 and the movable water spray pipe 24 through a water suction pump, cold water is sprayed from the water spray port 223 of the fixed water spray pipe 22 and the nozzle of the high-pressure nozzle 241 of the movable water spray pipe 24, and the water in the water tank 21 is pumped out through a water pump at the drain port 216 of the water tank 21 for cooling circulation.

[0120] The wheel hub 10 moves up and down rapidly through the water spray port 223 of the fixed water spray pipe 22. The cold water sprayed from the water spray port 223 can cool the periphery of the wheel hub 10, and the cold water sprayed from the nozzle of the high-pressure nozzle 241 can cool the bottom surface of the wheel hub 10. The rapid up and down movement of the wheel hub 10 will drive the turbine 233 to rotate forward and reverse, and then drive the rotating disk 231 to rotate, which not only accelerates the flow of water to cool the inner surface of the wheel hub, but also enables the position where the supporting roller 232 contacts the wheel hub 10 to be cooled.

[0121] After cooling is completed, the bracket 23 and the wheel hub fixture 25 are moved to the top of the water tank, and the exhaust port 212 at the opening 211 of the water tank 21 can dry the water stains on the wheel hub 10 .

[0122] Then the hub clamp 25 is moved upward and adjusted through the vertical sliding mechanism 262, and then the hub clamp 25 and the hub 10 thereon are moved to the hub wiping mechanism 34 through the horizontal sliding mechanism 261 to wipe off the residual water stains, thereby completing the hub water quenching cooling process.

After the wheel hub die-casting is completed, the wheel hub clamping mechanism 33 moves and adjusts in the direction of the wheel hub die-casting mechanism 41, clamps the die-cast wheel hub and then moves and adjusts in the direction away from the wheel hub die-casting mechanism 41, so that the wheel hub 10 is located above the wheel hub conveying mechanism 31, and then the wheel hub clamping mechanism 33 flips 180° to place the wheel hub 10 on the wheel hub conveying mechanism 31.

When passing through the wave tooth 4261 on the retaining ring 426, the friction force between the claw 421 and the uppermost filter screen 428 is greater than the blocking force of the toggle tooth 4261 on the retaining ring 426, so that the toggle tooth 4261 is deformed, so that the uppermost filter screen 428 is taken out, and the filter screens 428 except the uppermost filter screen 428 will be removed by the toggle tooth 4261, and only the uppermost filter screen is clamped by the claw 421.

[0142] When the filter screen 428 is lifted up and clamped on the bottom of the claw 421, the driving member 423 extends to move the bottoms of the claws 421 away from each other to support the filter screen 428, thereby clamping the filter screen 428. Figure 1 and Figure 2As shown, the secondary telescopic frame 4296 is extended, allowing the claw 421 to move with the filter to the top of the mold of the hub die-casting mechanism 41, and then the lifting power part 4297 drives the secondary telescopic frame 4296 to move downward, allowing the filter to contact the mold, and the driving part 423 is retracted, and the bottoms of the claws 421 are close to each other, so that the filter is placed on the mold, realizing the automatic placement of the filter on the mold.

[0143] The present invention is described in detail above in conjunction with the embodiments of the accompanying drawings. A person skilled in the art can make various variations of the present invention according to the above description. Therefore, certain details in the embodiments should not constitute a limitation of the present invention, and the scope of protection of the present invention shall be defined by the scope of the attached claims.
