Description

Technical Field

[0001] This utility model relates to a cooling device, specifically a cooling device for aluminum alloy wheel hub casting, belonging to the field of wheel hub casting technology. Background Technology

[0002] Cooling devices for aluminum alloy wheel casting are key equipment to ensure wheel quality. They are mainly used to quickly and uniformly cool the wheel blank after the casting process. After the aluminum material is forged, it needs to undergo a series of heat treatments such as high-temperature solution treatment, quenching, and low-temperature aging. The cooling process is crucial in the whole process. The blank is immersed in the water flow in the cooling pool. The high specific heat capacity of water quickly removes heat, promotes the rearrangement of the internal structure of the metal, and significantly improves the strength, toughness and dimensional stability of the blank, providing high-quality blanks for subsequent machining, surface coating and other processes.

[0003] However, existing cooling devices, when cooling wheel hubs, use a moving bracket to send the high-temperature wheel hubs into the cooling pool for water cooling, and then directly remove the wheel hubs and place them on the conveyor belt without treating the water stains remaining on the wheel hub surface. The residual water film is prone to forming water spots, which requires the wheel hubs to undergo additional polishing during subsequent processing, thereby increasing production costs and processing time. Utility Model Content

[0004] The purpose of this invention is to provide a cooling device for aluminum alloy wheel hub casting in order to solve the above problems. By rotating the structure, the air knife rotates around the wheel hub body, allowing the air knife to blow away water stains on the surface of the wheel hub body from multiple angles, thereby effectively preventing water film evaporation and the formation of water spots, reducing the workload of subsequent polishing, and thus reducing production costs.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a cooling device for casting aluminum alloy wheel hubs, comprising a cooling pool, with mounting seats fixedly connected to both sides of the cooling pool, a rotating structure provided on the mounting seats, the rotating structure including a fixed seat, a fixed seat fixedly connected to the mounting seats, a rotating shaft rotatably connected to the fixed seat, a support rod fixedly connected to the rotating shaft, a drying structure installed between the two support rods, the drying structure including an air knife, the air knife installed between the two support rods, the cooling pool being provided with a bracket, on which multiple wheel hub bodies are placed, and the air knife rotating around the wheel hub bodies.

[0006] Preferably, the top of the support rod is provided with a slot, and a locking block is installed on the air knife, the locking block engaging with the slot.

[0007] Preferably, the cross-section of the slot is trapezoidal, and the cross-section of the block is trapezoidal.

[0008] Preferably, a knob is rotatably connected to the support rod, and the end of the knob is threadedly connected to the locking block.

[0009] Preferably, a guide rail is fixedly connected to the mounting base, a slider is slidably connected to the guide rail, a rack is fixedly connected to the top of the slider, and a gear is fixedly connected to the rotating shaft, with the rack meshing with the gear.

[0010] Preferably, a hydraulic rod is mounted on the mounting base, and a protrusion is fixedly connected to the extended end of the hydraulic rod, the protrusion being fixedly connected to the slider.

[0011] Preferably, a blower is installed on the side wall of the mounting base, and a flexible hose is fixedly connected to the air outlet of the blower. The end of the flexible hose is fixedly connected to the air inlet of the air knife.

[0012] Preferably, the cooling pool has a water outlet at the end opposite to the blower, and a water inlet pipe is installed at the bottom of the cooling pool, with multiple nozzles evenly spaced on the water inlet pipe.

[0013] The beneficial effects of this utility model are as follows: a fixed base is fixedly connected to the mounting base, a rotating shaft is rotatably connected to the fixed base, a support rod is fixedly connected to the rotating shaft, and an air knife is installed between the two support rods. The cooling pool is equipped with a bracket, on which multiple wheel hub bodies are placed. The air knife rotates around the wheel hub body.

This effectively prevents water film evaporation and the formation of water spots, reduces the workload of subsequent polishing, and thus lowers production costs. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 As shown, a cooling device for casting aluminum alloy wheel hubs includes a cooling pool 1. Mounting seats 2 are fixedly connected to both sides of the cooling pool 1. A rotating structure 3 is provided on each mounting seat 2. The rotating structure 3 includes a fixed seat 301. A fixed seat 301 is fixedly connected to the mounting seat 2. A rotating shaft 302 is rotatably connected to the fixed seat 301. A support rod 303 is fixedly connected to the rotating shaft 302. A drying structure 4 is installed between two support rods 303. The drying structure 4 includes an air knife 401. The air knife 401 is installed between two support rods 303. The cooling pool 1 is provided with a bracket 6. Multiple wheel hub bodies 7 are placed on the bracket 6. The air knife 401 rotates around the wheel hub body 7.

[0018] As a technical optimization of this utility model, the top end of the support rod 303 is provided with a slot 304, and a locking block 305 is installed on the air knife 401. The locking block 305 engages with the slot 304, which can quickly position the air knife 401, making the installation work more convenient and flexible. The slot 304 and the locking block 305 have trapezoidal cross-sections, which can prevent the locking block 305 from slipping laterally, thereby increasing the stability of positioning. A knob 306 is rotatably connected to the support rod 303. The end of the knob 306 is threadedly connected to the locking block 305. The threaded connection between the knob 306 and the locking block 305 further reinforces the installation of the air knife 401, making the installation of the air knife 401 more stable and secure.

[0019] As a technical optimization of this utility model, a guide rail 307 is fixedly connected to the mounting base 2, a slider 308 is slidably connected to the guide rail 307, a rack 309 is fixedly connected to the top of the slider 308, a gear 310 is fixedly connected to the rotating shaft 302, the rack 309 meshes with the gear 310, a hydraulic rod 311 is installed on the mounting base 2, a protrusion 312 is fixedly connected to the extended end of the hydraulic rod 311, the protrusion 312 is fixedly connected to the slider 308, the extension and retraction of the hydraulic rod 311 drives the slider 308 to slide along the guide rail 307, and then the rack 309 moves with the slider 308, thereby driving the rotating shaft 302 to rotate through the meshing of the gear 310 and the rack 309, thereby driving the air knife 401 to rotate around the hub body 7 to achieve multi-angle blowing of water stains.

[0020] As a technical optimization of this utility model, a blower 402 is installed on the side wall of the mounting base 2. A hose 403 is fixedly connected to the air outlet of the blower 402. The end of the hose 403 is fixedly connected to the air inlet of the air knife 401. Airflow is delivered from the blower 402 to the air knife 401 through the hose 403. The air knife 401 generates a high-speed airflow to dry the wheel hub body 7.

[0021] As a technical optimization of this utility model, the cooling pool 1 is provided with an outlet 5 at the end away from the blower 402, and an inlet pipe 8 is installed at the bottom of the cooling pool 1. Multiple nozzles 9 are provided at equal intervals on the inlet pipe 8. The water flow in the cooling pool 1 is replaced through the outlet 5 and the inlet pipe 8 to ensure that the water temperature in the cooling pool 1 is maintained within the range required by the process and to avoid the cooling efficiency from decreasing due to excessively high water temperature.

[0022] In use, the bracket 6 is first installed on a mobile device such as a hydraulic lifting and translating platform or a gantry-type robotic arm. At this time, the air knife 401 is located on the side opposite to the vertical rod of the bracket 6, so that the air knife 401 does not obstruct the bracket 6 from moving the wheel hub body 7 into the cooling pool 1. Then, the mobile device drives the bracket 6 to move, so that the bracket 6 lifts up the multiple wheel hub bodies 7 on the placement frame and moves them into the cooling pool 1. Next, the control valve connected to the water inlet pipe 8 is activated, so that water flows into the water inlet pipe 8 and is sprayed out from multiple nozzles 9. The nozzles 9 are designed to ensure that the cooling water is evenly distributed to the wheel hub body. 7. Contact is maintained to avoid localized temperature differences, thereby improving cooling efficiency and uniformity. After cooling is complete, the bracket 6 lifts the hub body 7 to a suitable height. Then, the hydraulic rod 311 is activated. The extended end of the hydraulic rod 311 drives the protrusion 312 to move. The protrusion 312 pushes the slider 308 to slide on the guide rail 307. As the slider 308 slides, it drives the rack 309 at its top to mesh with the gear 310 on the rotating shaft 302, thereby driving the rotating shaft 302 to rotate. This causes the support rod 303 fixed on the rotating shaft 302 to rotate from one side of the hub body 7 to the other side. At this time, the installation... The air knife 401, positioned between the two support rods 303, rotates accordingly. Simultaneously, the blower 402 is activated, delivering high-pressure airflow to the air knife 401 via the hose 403. As the support rods 303 rotate, the air knife 401 can blow and clean the surface of the wheel hub body 7 from multiple angles, removing water stains and effectively preventing water spots from forming on the surface of the wheel hub body 7. This reduces subsequent workload and controls processing costs. After the drying process is completed, the hydraulic rod 311 retracts, the air knife 401 resets, and then the wheel hub body 7 is moved onto the conveyor belt via the bracket 6 for transport to the next processing stage. 1. When a damaged component needs to be replaced, turn the knobs 306 on the two support rods 303 outward in sequence, so that the two knobs 306 are no longer engaged with the locking blocks 305 at both ends of the air knife 401, thereby quickly releasing the restriction on the air knife 401, and making it easy to quickly remove the air knife 401 from the support rods 303. Then, engage the locking block 305 on the new air knife 401 with the locking groove 304 at the top of the support rod 303, thereby quickly achieving the initial positioning of the air knife 401. Then, tighten the knobs 306 to thread the locking block 305 to the support rod 303 to ensure that the air knife 401 is stable.
