Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy wheel hub casting technology, and in particular to an automatic cleaning structure for a crucible platform. Background Technology

[0002] In the differential pressure casting process for aluminum alloy wheels, the crucible containing molten aluminum needs to be periodically transferred between a fixed crucible platform and a movable platform for replacement. However, during the transfer process, the crucible is prone to axial and radial swaying due to mechanical vibration and positioning deviations when moving from the movable platform to the crucible platform. This swaying causes molten aluminum to overflow from the crucible opening, dripping and solidifying on the surface of the crucible platform to form an aluminum dross accumulation layer. As the aluminum dross continues to accumulate, the flatness of the platform surface deteriorates significantly, further increasing the swaying amplitude during subsequent crucible transfers, creating a vicious cycle of "molten aluminum overflow - uneven platform - increased swaying - more overflow." Ultimately, this forces the equipment to be shut down for manual cleaning, causing production line interruptions and losses in production efficiency.

[0003] There is a lack of automated cleaning solutions for this problem in the current technology. There is an urgent need to develop an automated cleaning structure for crucible platforms that is integrated into the crucible replacement process to eliminate the risk of aluminum slag accumulation and ensure continuous production. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a crucible platform cleaning structure that can automatically remove solidified aluminum liquid overflowing from the crucible platform, preventing the accumulation of aluminum liquid from causing platform unevenness and increased crucible shaking, thereby avoiding production interruptions.

[0005] The technical solution adopted in this utility model is as follows:

[0006] An automatic cleaning structure for a crucible platform includes a cleaning assembly mounted on the crucible platform. The cleaning assembly includes a support beam parallel to the platform surface and a rotating brush rotatably connected to the bottom of the support beam. A drive motor is mounted on the support beam and is connected to the rotating brush. The support beam is movably connected to the crucible platform via a linear slide rail mechanism to achieve reciprocating motion along the length of the platform.

[0007] Preferably, the linear slide rail mechanism includes guide rails symmetrically installed on both sides of the crucible platform, with grooves provided on the guide rails, and a support beam slidably connected in the grooves via a square slide block.

[0008] Preferably, a drive sprocket and a driven sprocket are respectively provided at both ends of the guide rail along its length, and a transmission chain is meshed between the drive sprocket and the driven sprocket, with the support beam rigidly connected to the connecting plate of the chain.

[0009] Preferably, the clearance between the square slide block and the slide groove is 0.1-0.3 mm.

[0010] Preferably, the cleaning assembly includes a scraper fixedly connected to the bottom of the support beam. The scraper is disposed corresponding to the surface of the crucible platform, and the bottom end of the scraper abuts against the surface of the crucible platform to scrape off the solidified aluminum liquid adhering to the platform surface.

[0011] Preferably, the bottom of the scraper is provided with an extension piece corresponding to the roller groove on the crucible platform, and the extension piece can extend into the roller groove.

[0012] Preferably, the cleaning assembly includes a blowing assembly for blowing the surface of the crucible platform.

[0013] Preferably, the blowing assembly further includes a secondary air duct disposed behind the rotating brush. The secondary air duct covers the crucible platform along its length, and the crucible platform is densely covered with air outlets. The secondary air duct is connected to a compressed air source.

[0014] The beneficial effects of this utility model are as follows: Addressing the problems of aluminum dross accumulation due to aluminum molten metal overflow and inefficient manual cleaning in the background art, this utility model utilizes the synergistic action of rotating brushes, scrapers, and blowing components to efficiently remove aluminum dross from the platform surface and roller grooves, breaking the vicious cycle of "aluminum molten metal overflow - platform unevenness - increased shaking"; automated cleaning replaces manual cleaning, avoiding production line downtime and ensuring continuous production; it eliminates the safety hazards of manual cleaning of high-temperature platforms and reduces labor intensity; dual-stage blowing prevents secondary adhesion of aluminum dross, ensuring cleanliness, meeting precision casting requirements, and significantly reducing equipment maintenance costs.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figure 1-2 As shown, an automatic cleaning structure for a crucible platform includes a cleaning assembly mounted on the crucible platform for removing solidified aluminum dross from the platform surface. The cleaning assembly includes a support beam 10 parallel to the platform surface and a rotating brush 11 rotatably connected to the bottom of the support beam 10 via a bearing seat. A drive motor 12 is mounted on the support beam 10, and its output shaft is connected to the main shaft of the rotating brush 11 via a gear transmission mechanism, providing rotational power for the rotating brush 11 to clean the aluminum dross. The support beam 10 is movably connected to the crucible platform via a linear slide rail mechanism, enabling reciprocating motion along the length of the platform. In use, the drive motor 12 drives the rotating brush 11 to rotate close to the crucible platform, scraping the platform surface and peeling off the attached solidified aluminum liquid; simultaneously, the support beam 10 drives the cleaning assembly to move along the linear slide rail, completely peeling off the solidified aluminum dross from the crucible platform and breaking up large aluminum droplets. This embodiment uses the mechanical scraping action of the rotating brush 11 to directly destroy the adhesion interface between the aluminum slag and the platform, solving the problems of low efficiency and incomplete cleaning in traditional manual removal; the linear slide rail mechanism ensures that the cleaning covers the entire platform surface and eliminates cleaning dead corners.

[0021] In a preferred embodiment, the linear slide rail mechanism includes guide rails 21 symmetrically mounted on both sides of the crucible platform. The guide rails 21 have grooves 22, and the support beam 10 is slidably connected to the grooves 22 via square slide blocks 23. The clearance between the square slide block 23 and the groove 22 is controlled within the range of 0.1-0.3 mm, allowing the support beam 10 to move along the linear slide rails on the crucible platform.

[0022] Preferably, the guide rail 21 has a drive sprocket 24 and a driven sprocket 25 at its two ends along its length, respectively. A transmission chain 26 meshes between the drive sprocket 24 and the driven sprocket 25, and the support beam 10 is rigidly connected to the connecting plate of the chain. In use, the servo motor 27 drives the drive sprocket 24 to rotate, and drives the support beam 10 to move back and forth through the transmission chain 26, thereby completing the reciprocating scraping operation on the surface of the crucible platform. The electrical control components, such as the drive circuit and encoder feedback system of the servo motor 27, all adopt mature solutions from the prior art to achieve precise drive and closed-loop position control.

[0023] Preferably, the cleaning assembly further includes a scraper 30 fixedly connected to the bottom of the support beam 10. The scraper 30 is positioned corresponding to the surface of the crucible platform and is used to scrape off the solidified aluminum molten metal adhering to the platform surface. In use, the support beam 10 drives the scraper 30 to reciprocate, and the bottom end of the scraper 30 abuts against the surface of the crucible platform, producing a shearing and peeling effect on the solidified aluminum dross. The scraper 30 is particularly effective at removing dense aluminum layers that are difficult to remove with a brush.

[0024] Preferably, the scraper 30 has an extension plate 31 at its bottom corresponding to the roller groove on the crucible platform. The extension plate 31 can extend into the roller groove to peel off and scrape away the solidified aluminum liquid adhering to the roller groove. This eliminates cleaning dead corners, avoids aluminum slag accumulation affecting the crucible positioning accuracy, and improves the cleaning effect.

[0025] Preferably, the cleaning assembly further includes a spraying assembly for blowing the crucible platform surface, further improving the cleaning effect of the crucible platform. The spraying assembly includes a plurality of nozzles 41 corresponding to the crucible platform surface. Preferably, the nozzles 41 are flat fan-shaped nozzles, and the nozzles 41 are connected to a compressed air source to supply high-pressure air to the nozzles 41. In use, the high-pressure air is sprayed onto the crucible platform surface through the nozzles 41, blowing away aluminum slag and other debris adhering to the platform. Combined with the mechanical scraping action of the rotating brush 11, a cleaning effect of brushing and blowing is achieved. The high-pressure fan-shaped airflow can quickly disperse loose aluminum slag, preventing it from adhering to the platform surface again and improving cleaning efficiency; the wide coverage characteristic of the flat nozzles 41 can reduce the number of nozzles 41 and reduce system complexity. The pressure regulating valve of the compressed air source, the solenoid valve control unit, and other pneumatic components and related electrical control modules all adopt standard components and control logic in the prior art to realize the on / off of airflow and pressure regulation.

[0026] Preferably, the blowing assembly further includes a secondary air duct 42 disposed behind the rotating brush 11. The secondary air duct 42 has numerous air outlets corresponding to the crucible platform, and its length covers the crucible platform. The secondary air duct 42 is connected to a compressed air source, which promptly blows the solidified aluminum liquid away from the platform after the rotating brush 11 loosens it. The wide airflow of the secondary air duct 42 can thoroughly clean the entire surface of the platform, especially effectively removing fine aluminum slag particles remaining after the rotating brush 11 has been cleaned.

[0027] It should be noted that the power supply circuits, overload protection devices, and linkage control logic of various actuators (such as the start triggering of the cleaning process, travel limit protection, fault alarm, etc.) of the electrical equipment such as the drive motor 12, servo motor 27, and solenoid valve involved in this utility model are all implemented using mature electrical control systems and programmable logic controller (PLC) programming schemes in the prior art, and will not be described in detail here.

[0028] The above-disclosed embodiments are merely specific examples of this utility model, but this utility model is not limited thereto. For those skilled in the art, any modifications made without departing from the principle of this utility model should be considered as protected by this utility model.
