[0021] like Figure 1-2As shown, a device for testing the corrosion resistance of aluminum-based materials after forming includes a test container 1, an eccentric shaft 6, a tester 7, a liquid inlet hopper 8, and a leakage hole 9. The test container 1 is provided with a height adjustment component for driving the tester 7 to rise and fall, and the height adjustment component is provided with a motor 5 for driving the tester 7 to rotate. The output shaft of the motor 5 is connected to the tester 7 through the eccentric shaft 6. A leakage hole 9 is provided at the bottom of the tester 7, and a liquid inlet hopper 8 is provided at a high position on the side wall of the tester 7.

[0022] Specifically, the height of the tester 7 is adjusted by adjusting the height of the assembly to contact and adapt to the thickness of the plate, and it is also convenient for taking and placing the plate. The eccentric shaft 6 is driven to rotate by the motor 5, so that the eccentric shaft 6 drives the tester 7 to rotate eccentrically to increase the friction area. At the same time, the corrosive liquid is poured into the test container 1 from the liquid inlet hopper 8. While rubbing, the corrosive liquid flows out from the leakage hole 9 onto the plate, and the performance of the plate is tested in conjunction with the friction.

[0023] Furthermore, it also includes a fastening ring 15, a first fixing ear 16, a second fixing ear 17, a stud 18, and a nut 19. The bottom edge of the tester 7 is provided with a makeshift groove 20 for avoiding the fastening ring 15. The second fixing ears 17 are fixedly provided on both sides of the bottom of the tester 7. The first fixing ears 16 are fixedly connected to both sides of the fastening ring 15. The first fixing ear 16 is fixedly connected to a stud 18 that can penetrate the second fixing ear 17, and the stud 18 is threaded with a nut 19.

[0024] Specifically, by screwing the nut 19 to tighten the stud 18, and then tightening the fastening ring 15 in the clearance groove 20, the tester 7 can be in contact with the plate. At the same time, the sandpaper is tightened by the fastening ring 15. There are holes on the sandpaper corresponding to the leakage holes 9, which makes it easy to replace the sandpaper, and then test the wear resistance of the plate.

[0025] Furthermore, the height adjustment component includes a stand 2, an electric telescopic rod 3, and a horizontal plate 4. The stand 2 is arranged on the top of both sides of the test container 1. The top of the stand 2 is provided with an electric telescopic rod 3 that can drive the horizontal plate 4 to rise and fall vertically, and the motor 5 is fixedly installed on the horizontal plate 4.

[0026] Specifically, the height of the horizontal plate 4 can be adjusted by starting the electric telescopic rod 3 to extend and retract, thereby adjusting the height of the tester 7 .

[0027] Furthermore, fastening components are fixedly connected on both sides of the test container 1 for fixing the plate. The fastening components include a fixing plate 11, a screw 12, a pressure plate 13, and a handle 14. One end of the fixing plate 11 is fixedly connected to the test container 1, and a screw 12 is screwed on the fixing plate 11. The top end of the screw 12 is fixedly connected to the handle 14, and the bottom end of the screw 12 is rotatably connected to the pressure plate 13.

[0028] Specifically, the screw rod 12 is screwed by the handle 14 , and then the screw rod 12 is raised and lowered, and the plate is fixed by the pressing plate 13 to prevent the plate from slipping during the test.

[0029] Furthermore, a faucet 10 is provided on one side of the test container 1 for draining the liquid in the test container 1 .

[0030] Furthermore, a fastening ring 15 protrudes from the bottom of the tester 7 so that the bottom of the tester 7 can contact the plate.

[0031] Furthermore, the fastening ring 15 is annular and can fix sandpaper.

[0032] In the above structure, when it is necessary to test the corrosion resistance and wear resistance of the surface treatment of the aluminum-based plate, first place the plate in the test container 1, then tighten the plate by screwing the screw 12, then start the electric telescopic rod 3 to drive the horizontal plate 4 to descend, and then make the tester 7 descend, and then the sandpaper contacts the plate, and then pour the corrosive liquid from the liquid inlet hopper 8 into the tester 7, start the motor 5 to drive the eccentric shaft 6 to rotate, so that the sandpaper and the plate rub, and the corrosive liquid flows out from the leakage hole 9. After a certain period of time, stop the motor 5, and start the electric telescopic rod 3 to contract and lift the tester 7, and then drain the corrosive liquid in the test container 1 through the faucet 10. Finally, the plate in the test container 1 can be taken out for observation, and the wear resistance and corrosion resistance can be known from the damage and corrosion conditions.
