[0002] A hollow ultra-thin wall aluminum alloy profile forming device is a device used to process specific aluminum alloy profiles. Its overall structure is designed around the profile forming process and mainly includes a basic frame, core forming components and necessary auxiliary structures.

[0003] Existing hollow ultra-thin wall aluminum alloy profile forming devices may have difficulties in thoroughly scraping off impurities adhering to the surface of the extrusion rollers and in efficiently collecting these scraped-off impurities.

Furthermore, the scraped-off impurities cannot be effectively collected, which can easily cause them to accumulate inside the device, thus adversely affecting subsequent processing steps. To address this issue, we propose a hollow ultra-thin wall aluminum alloy profile forming device. Utility Model Content

[0017] The feed frame 3 is located on the front side of the inner wall of the working frame 1. It is used to guide the aluminum alloy billet into the device and ensure that the billet is accurately fed into the forming area between the upper extrusion roller 4 and the lower extrusion roller 5 to prevent deviation. The upper extrusion roller 4 is installed on the upper part of the inner wall of the working frame 1 and cooperates with the lower extrusion roller 5.

[0019] The fixing rod 607 is installed inside the rectangular groove 606, and the inner wall of the connecting rod 604 is slidably connected to the outer wall of the fixing rod 607, which can further stabilize the movement trajectory of the connecting rod 604 and prevent the scraper from deviating during cleaning.

[0023] Please see the appendix Figure 1 and appendix Figure 8 An electrostatic spraying assembly 7 is provided above the feed frame 3. The electrostatic spraying assembly 7 includes a metering pump 701, which is fixedly connected to the outer right side wall of the working frame 1. The output end of the metering pump 701 is fixedly connected to an output pipe 702, and the lower end of the output pipe 702 is fixedly connected to a straight pipe 703. The straight pipe 703 is fixedly connected to the inner wall of another set of brackets 2. Multiple sets of nozzles 704 distributed at equal intervals are fixedly installed on the lower surface of the straight pipe 703. The input end of the metering pump 701 is fixedly connected to a suction pipe 705, and the lower end of the suction pipe 705 is fixedly connected to a storage tank 706. The storage tank 706 is fixedly installed on the right side surface of the working frame 1 and is located in front of the second hydraulic rod 603.

[0024] The metering pump 701 is fixed to the right outer wall of the working frame 1 as a power source. It accurately extracts the lubricating coating material from the storage tank 706 and controls the output flow rate to ensure uniform coating thickness. It is the core component for controlling the spraying amount. The storage tank 706 is fixed to the right surface of the working frame 1 and is used to store the lubricating coating material to provide a stable raw material supply for the electrostatic spraying assembly 7.

[0025] Specifically, the electrostatic spraying assembly 7 stores the lubricating coating in the storage tank 706. The coating is then drawn by the metering pump 701 through the suction pipe 705 and transported to the straight pipe 703 through the output pipe 702. The coating is then sprayed onto the blank above the feed frame 3 by multiple sets of equally spaced nozzles 704 on the lower surface of the straight pipe 703. The metering pump 701 controls the output of the coating, which, together with the equally spaced nozzles 704, forms a uniform lubricating coating on the surface of the blank. This reduces friction between the blank and the upper extrusion roller 4 and the lower extrusion roller 5, preventing damage to the profile surface due to friction and ensuring forming quality.

[0026] Working principle of this utility model: This utility model is a hollow ultra-thin-walled aluminum alloy profile forming device. First, the operator feeds the aluminum alloy billet into the working frame 1 through the feeding frame 3. The feeding frame 3 guides the billet precisely into the forming area between the upper extrusion roller 4 and the lower extrusion roller 5. The upper extrusion roller 4 and the lower extrusion roller 5 rotate relative to each other and apply pressure to the billet. Through the extrusion action, the billet is shaped into an ultra-thin-walled profile. During the extrusion process, the operator activates the first hydraulic rod 601 to drive the first scraper 602 to adhere to the surface of the upper extrusion roller 4, and activates the second hydraulic rod 603 to drive the second scraper 605 to engage with the surface of the lower extrusion roller 5 through the connecting rod 604, scraping away aluminum chips and other impurities adhering to the surfaces of the two rollers respectively. At the same time, the operator activates the negative pressure air. Machine 615 creates negative pressure within the collection box 608, connecting pipe 609, main pipe 610, branch pipe 611, and chip suction frame 612. The chip suction frame 612 adsorbs scraped impurities, which are then transported to the collection box 608 via the pipeline. The filter screen 613 blocks impurities from entering the blower, achieving centralized collection of impurities. Before the billet enters the extrusion area, the lubricating coating in the storage tank 706 is drawn by the metering pump 701 through the suction pipe 705 and transported to the straight pipe 703 through the output pipe 702. Then, the nozzle 704 on the lower surface of the straight pipe 703 evenly sprays the coating onto the surface of the billet, forming a lubricating coating and reducing friction between the billet and the extrusion rollers. Finally, the billet, after lubrication, extrusion, and cleaning, is formed into a hollow ultra-thin-walled aluminum alloy profile, completing the processing flow.

[0027] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
