Description

Technical Field

[0001] The invention relates to the technical field of thin plate production, in particular to a polishing device for light alloy thin plates. Background Art

[0002] At present, magnesium alloy and aluminum alloy have significant advantages in lightweight, and have very broad application prospects in the process of product lightweight development; for example, magnesium alloy and aluminum alloy thin plates are widely used in 3C products, radar, automobiles and other fields. With the development of lightweight and portable whole products, more and more magnesium / aluminum alloy thin plates are used. However, magnesium / aluminum alloy plates are difficult to process during the polishing process due to their soft texture, especially thin plates with a thickness of ≤0.4mm have very low production efficiency and qualified rate during polishing. When processed with conventional sanding belt style polishing machines, thin plates are easy to stick to the sanding belt and roll into the sanding belt, resulting in scrapping of the plate, or even jamming the equipment and causing damage to the equipment; when processed with vacuum suction cup style polishing machines, due to the effect of vacuum suction, suction holes are easy to appear, resulting in uneven plate surface and scrapping. Therefore, for soft thin plates with a thickness of ≤0.4mm, it is of great practical significance to develop suitable polishing equipment for the industrial application of thin plates.

[0003] The utility model with the existing publication number CN216179490U discloses a double-sided partial polishing mechanism for aluminum-magnesium alloy thin plates, which includes a polishing seat and a flipping mechanism, and the flipping mechanism includes a driving cylinder, a sliding seat, a rotating shaft and a transmission gear; the sliding seat is connected to the driving cylinder, a slider is provided at the lower end of the sliding seat, and a slide groove is provided on the polishing seat, and a first tooth segment is provided on the sliding seat; the end face of the polishing seat is provided with a rotating bearing seat, one end of the rotating shaft is connected to the transmission gear, and the other end is provided on the rotating bearing seat, a connecting sleeve is provided on the rotating shaft, and a clamping assembly is installed on the connecting sleeve. The aluminum-magnesium alloy thin plate is clamped and fixed by the clamping assembly, and after single-sided polishing, the driving cylinder pushes the sliding seat, and the sliding seat slides along the slide groove through the slider, driving the transmission gear to rotate, so that the rotating shaft rotates on the rotating bearing seat, and the aluminum-magnesium alloy thin plate on the clamping assembly is flipped, replacing manual flipping, and avoiding damage caused by excessive temperature of the polished aluminum-magnesium alloy thin plate. Although this structure solves the problem of automatic double-sided polishing of thin plates, it cannot solve the problem that thin plates are easily stuck to the sanding belt and rolled into the sanding belt during polishing, resulting in the scrapping of the plates.

[0040] Further, to better illustrate the structure of the device of the present invention, the following is described through a specific operation process, specifically as follows:

[0041] The specific grinding process is as follows: The equipment is powered on, and the abrasive belt 14 is tightened by the abrasive belt support cylinder 11. On the control panel 6, the appropriate gap between the conveyor belt 3 and the abrasive belt 14 is adjusted through the conveyor belt lifting platform 15. The circulating water pump 2 is turned on, and water is sprayed onto the abrasive belt 14 through the circulating water spray pipe 5 for cooling. The conveyor belt motor 16 is turned on to make the conveyor belt 3 run normally. The driving motor 18 of the abrasive belt 14 is turned on to make the abrasive belt 14 run normally. After the equipment is debugged normally, the thin plate to be ground is placed on the conveyor belt 3 at the feeding end, and the plate enters under the abrasive belt 14 through the conveyor belt 3 together to start polishing. The thin plate moves forward under the action of the friction force between the conveyor belt 3 and the abrasive belt 14. Since the thin plate is very thin, it is prone to warping in the direction of the movement of the abrasive belt 14 under the influence of frictional heat during the grinding process and runs along with the abrasive belt 14. Then, by starting the anti-sticking roller 13, the thin plate is strongly guided into the grinding guide roller 12 at the discharging end with its anti-sticking wheel like a flying tooth, so that the thin plate is normally led out from the discharging port, and one-time grinding of the thin plate is completed. After the thin plate that needs to be ground multiple times is ground once, the thin plate is taken down from the discharging end and put back into the conveyor belt 3 from the feeding end again. During the grinding process, as the thickness of the thin plate decreases, the gap between the conveyor belt 3 and the abrasive belt 14 is adjusted in a timely manner.
