Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy oxidation technology, specifically to an anodizing device for protective aluminum alloy profiles. Background Technology

[0002] Aluminum alloy profiles are one of the most widely used non-ferrous metal structural materials in industry. To overcome the shortcomings of aluminum alloys in terms of surface hardness and wear resistance, surface treatment technology has become an indispensable part of the use of aluminum alloys. Among them, aluminum alloy anodizing technology is the most commonly used surface treatment technology. Aluminum alloy anodizing technology uses aluminum or aluminum alloy products as anodes, placing them in an electrolyte solution for electrolytic treatment. The electrolysis process forms an aluminum oxide film on the surface, enhancing the corrosion resistance and wear resistance of the aluminum alloy surface.

[0003] Chinese patent application CN202321233027.6 discloses an anodizing device for aluminum alloy profiles, including a housing. Observation windows are provided at the center of the front end face, the center of the rear end face, the center of one side wall, and the center of the other side wall of the housing. First sliding grooves are symmetrically formed on both sides of the center of the upper end face of the housing, with sliders slidably connected to both ends of the two first sliding grooves. Limiting blocks are provided at the rear of both first sliding grooves. First motors are symmetrically fixedly connected on both sides of the center of the upper end face of the housing, with the output ends of the two first motors penetrating the housing and extending into the two first sliding grooves. This device can provide stable clamping during the anodizing of multiple aluminum alloys, but the clamping parts cannot contact the electrolyte, thus hindering oxidation and affecting the oxidation effect.

[0004] Based on this, the present invention designs an anodizing device for protective aluminum alloy profiles to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an anodizing device for protective aluminum alloy profiles.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An anodizing device for protective aluminum alloy profiles includes an oxidation tank. A cathode conductive end is connected to one side of the oxidation tank, and a cathode plate is connected to the cathode conductive end. An anode conductive end is connected to the other side of the oxidation tank, and a conductive frame is connected to the anode conductive end. A conductive rod is installed inside the conductive frame. A mounting frame is fixed at the top of the oxidation tank. Four sets of slide rails are symmetrically fixed at the bottom of the horizontal part of the mounting frame. Two sets of sliding plates slide symmetrically on the slide rails. A screw is threaded through the side of the sliding plate. A servo motor is installed at the end of the screw. A clamping bar is fixed at the bottom of the sliding plate, and the bottom end of the clamping bar is located inside the oxidation tank.

[0008] Furthermore, the vertical distance from the bottom of the mounting frame to the top of the oxidation tank is equal to the height of the inner cavity of the oxidation tank, the conductive rods are evenly spaced on the side of the conductive frame, and the length of the clamping strip is slightly less than the height of the inner cavity of the oxidation tank.

[0009] Furthermore, the bottom of the horizontal part of the mounting bracket is provided with four sets of sliding grooves, in which sliders slide. A connecting plate is fixed to the end of the slider, and the slide rail is threadedly fixed to the connecting plate. An adjusting screw is threaded through the side of the slider, and the adjusting screw is rotatably arranged through both sides of the mounting bracket.

[0010] Furthermore, the slide groove is provided through both sides of the mounting frame and has plugs sliding at both ends. The plugs are threadedly fixed to the side of the mounting frame. The adjusting screw rotates through the plugs, and the bottom end of the slider is flush with the bottom end of the horizontal part of the mounting frame.

[0011] Furthermore, the inner wall of the conductive frame is provided with vertical sliding grooves at equal intervals, and a conductive vertical slider slides in the vertical sliding grooves. A lower conductive rod is fixed to the side of the vertical slider, and an insulating rod is fixed to the top of the vertical slider. The insulating rod moves through the top of the conductive frame and is connected to a lifting plate.

[0015] 1. By setting up four sets of slide rails, slide plates, screws, servo motors and clamping bars, the clamping bars can be switched when clamping and oxidizing aluminum alloy profiles. First, two sets of servo motors are used to control the clamping bars to contact and fix the aluminum alloy profiles on the side. Then, the other two sets of servo motors are switched to control the clamping bars to contact and fix the aluminum alloy profiles on the side, so that the initial clamping bars and aluminum alloy profiles are separated, exposing the clamping part for oxidation.

[0016] 2. By setting up a sliding groove, slider, connecting plate, and adjusting screw, the position of the sliding rail and clamp can be adjusted by rotating the adjusting screw and utilizing its threaded engagement with the slider. This allows for easy adjustment of the clamp's position according to the dimensions of the aluminum alloy profile. The system also includes a vertical sliding groove, conductive vertical slider, lower conductive rod, insulating rod, lifting plate, and cylinder. The cylinder continuously extends and retracts its internal piston rod. Through the sliding engagement of the conductive vertical slider and vertical sliding groove, the lower conductive rod moves upward to replace the conductive rod and provide bottom support for the aluminum alloy profile, exposing the oxide layer at the contact point with the conductive rod. Finally, an installation groove and rotating rod are provided to assist in the vertical movement of the aluminum alloy profile. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] In some embodiments, please refer to the accompanying drawings. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 An anodizing device for protective aluminum alloy profiles includes an oxidation pool 1, a cathode conductive end 2 connected to one side of the oxidation pool 1, a cathode plate 3 connected to the cathode conductive end 2, an anode conductive end 4 connected to the other side of the oxidation pool 1, a conductive frame 5 connected to the anode conductive end 4, a conductive rod 6 installed inside the conductive frame 5, a mounting frame 7 fixed at the top of the oxidation pool 1, four sets of slide rails 8 symmetrically fixed at the bottom of the horizontal part of the mounting frame 7, two sets of sliding plates 9 symmetrically sliding on the slide rails 8, a screw 10 threaded through the side of the sliding plate 9, a servo motor 11 installed at the end of the screw 10, and a clamping strip 12 fixed at the bottom of the sliding plate 9, with the bottom end of the clamping strip 12 located inside the oxidation pool 1.

[0028] In this embodiment of the utility model, the aluminum alloy profile to be oxidized is placed in the oxidation tank 1, with its bottom end resting on the conductive rod 6 for support. Two sets of slide rails 8 are selected, and the servo motor 11 is moved to drive the screw 10 to rotate. The screw 10 and the slide plate 9 are threaded together to move the two sets of slide plates 9, thereby moving the clamping strip 12 to contact the side of the aluminum alloy plate for positioning. The power is connected by the cathode conductive end 2 and the anode conductive end 4 to anodize the aluminum alloy profile. During the process, one set of servo motors 11 is reversed first to separate the two sets of clamping strips 12 controlled by it from the aluminum alloy profile, allowing the contact part to be exposed to oxidation. At the same time, the other two sets of servo motors 11 are started to make the clamping strips 12 controlled by them contact and position the aluminum alloy profile. Finally, the remaining set of servo motors 11 is reversed to separate the two sets of clamping strips 12 controlled by it from the aluminum alloy profile, allowing the contact part to be exposed to oxidation, thereby realizing the electrolytic oxidation of the clamping part.

[0029] In this embodiment of the utility model, by setting four sets of slide rails 8, slide plates 9, screws 10, servo motors 11 and clamping bars 12, when clamping and oxidizing aluminum alloy profiles, the clamping bars 12 can be switched. First, two sets of servo motors 11 are used to control the clamping bars 12 to contact and fix the side of the aluminum alloy profile. Then, the other two sets of servo motors 11 are switched to control the clamping bars 12 to contact and fix the side of the aluminum alloy profile, so that the initial clamping bars 12 and aluminum alloy profiles are separated, exposing the clamping part for oxidation.

[0030] In one embodiment of this utility model, the vertical distance from the bottom of the mounting bracket 7 to the top of the oxidation tank 1 is equal to the height of the inner cavity of the oxidation tank 1. The conductive rods 6 are evenly spaced on the side of the conductive frame 5 to facilitate support of the aluminum alloy profile from the bottom. The length of the clamping strip 12 is slightly less than the height of the inner cavity of the oxidation tank 1 to avoid contact with the bottom of the inner cavity of the oxidation tank 1. The bottom of the horizontal part of the mounting bracket 7 is provided with four sets of sliding grooves 13. The sliding grooves 13 are provided through both sides of the mounting bracket 7 and the two ends are slidably blocked by blocks 17. The blocks 17 are threaded to the side of the mounting bracket 7. The sliding sliders 1 slide in the sliding grooves 13. 4. The bottom end of the slider 14 is flush with the bottom end of the horizontal part of the mounting bracket 7. A connecting plate 15 is fixed to the end of the slider 14. The slide rail 8 is threadedly fixed to the connecting plate 15. An adjusting screw 16 is threaded through the side of the slider 14. The adjusting screw 16 rotates through the block 17. The adjusting screw 16 rotates through both sides of the mounting bracket 7. By rotating the adjusting screw 16, its position can be adjusted by using its threaded engagement with the slider 14, thereby adjusting the position of the slide rail 8 and the clamping bar 12. This makes it easy to adjust the position of the clamping bar 12 according to the size of the aluminum alloy profile for positioning.

[0031] In some embodiments, such as Figure 1 , Figure 4 and Figure 5As shown, vertical sliding grooves 18 are evenly spaced on the inner wall of the conductive frame 5. The bottom of the vertical sliding grooves 18 is lower than the bottom of the conductive rod 6. A conductive vertical slider 19 slides in the vertical sliding grooves 18. A lower conductive rod 20 is fixed to the side of the vertical slider 19. The lower conductive rod 20 and the conductive rod 6 are arranged alternately at equal intervals. An insulating rod 21 is fixed to the top of the vertical slider 19. The sum of the length of the insulating rod 21 and the height of the conductive vertical slider 19 is equal to the vertical distance from the bottom of the vertical sliding groove 18 to the top of the oxidation tank 1. The insulating rod 21 movably passes through the top of the conductive frame 5 and is connected to a lifting plate 22. A cylinder 23 is installed on the side of the oxidation tank 1. The bottom of the lifting plate 22 is connected to the piston rod of the cylinder 23. An installation groove 24 is opened on the side of the clamping strip 12. A rotating rod 25 rotates at equal intervals in the installation groove 24. The clamping strip 12 and the rotating rod 25 are made of insulating material.

[0032] In this embodiment of the invention, the aluminum alloy profile to be oxidized is placed in the oxidation tank 1, with its bottom end resting on the conductive rod 6 for support. Depending on its size, the position can be adjusted by rotating the adjusting screw 16, utilizing its threaded engagement with the slider 14. This adjusts the positions of the slide rails 8 and clamping bars 12. Then, two sets of slide rails 8 are selected, and the servo motor 11 is moved to drive the screw 10 to rotate. Utilizing the threaded engagement between the screw 10 and the sliding plate 9, the two sets of sliding plates 9 are moved, thereby moving the clamping bars 12 to contact the side of the aluminum alloy sheet for positioning. Power is then connected via the cathode conductive end 2 and the anode conductive end 4 to anodize the aluminum alloy profile. During the process, one set of servo motors 11 is first reversed to control... The two sets of clamping bars 12 separate from the aluminum alloy profile, exposing the oxidation at the contact point. At the same time, the other two sets of servo motors 11 are started, so that the clamping bars 12 controlled by them contact and position the aluminum alloy profile. Finally, the remaining set of servo motors 11 is reversed to separate the two sets of clamping bars 12 controlled by them from the aluminum alloy profile, exposing the oxidation at the contact point, thereby realizing the electrolytic oxidation of the clamping part. At the same time, the cylinder 23 continuously extends and retracts the internal piston rod. Under the sliding cooperation of the conductive vertical slider 19 and the vertical slide groove 18, the lower conductive rod 20 is driven to move upward to replace the conductive rod 6 to support the bottom of the aluminum alloy profile. During the process, with the cooperation of the rotating rod 25, the aluminum alloy profile is assisted to move up and down, so that the part that contacts the conductive rod 6 is exposed to oxidation.

[0033] In this embodiment of the utility model, by setting up a vertical sliding groove 18, a conductive vertical sliding block 19, a lower conductive rod 20, an insulating rod 21, a lifting plate 22, and a cylinder 23, the cylinder 23 continuously extends and retracts the internal piston rod. Under the sliding cooperation of the conductive vertical sliding block 19 and the vertical sliding groove 18, the lower conductive rod 20 is driven to move upward to replace the conductive rod 6 and provide bottom support for the aluminum alloy profile, so that the part in contact with the conductive rod 6 is exposed to oxidation. By setting up an installation groove 24 and a rotating rod 25, the aluminum alloy profile is assisted to move up and down with the cooperation of the rotating rod 25.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
