Description

Technical Field

[0001] This utility model relates to the field of anodizing equipment technology, specifically to an anti-scratch device for anodizing aluminum profiles. Background Technology

[0002] Anodizing of aluminum profiles, as an important surface treatment technology, forms a dense aluminum oxide film on the surface of aluminum profiles through electrolysis, significantly improving the corrosion resistance, wear resistance, and insulation properties of the aluminum profiles. It is widely used in construction, electronics, automotive, aerospace, and other fields. However, in actual production, scratches on aluminum profiles during the anodizing process have long plagued the industry, becoming a key factor restricting product quality and production efficiency.

[0003] In existing technologies, operators must manually place aluminum profiles into an electrolytic cell for oxidation treatment. However, due to the considerable depth of the electrolytic cell (typically exceeding 1 meter), it is difficult to precisely control the movement trajectory of the aluminum profile during manual placement, resulting in frequent contact between the aluminum profile and the inner wall of the electrolytic cell. This contact easily forms scratches or abrasions on the surface of the aluminum profile, severely affecting the uniformity and integrity of the oxide film, thereby reducing the product's corrosion resistance and appearance quality. Simultaneously, factors such as electrolyte flow, equipment vibration, or operational errors can cause slight movement or shaking of the aluminum profile during electrolysis, and the friction and collision between the aluminum profile and the inner wall of the electrolytic cell further exacerbate surface damage. Utility Model Content

[0004] The purpose of this invention is to provide an anti-scratch device for anodizing aluminum profiles to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-scratch device for aluminum profile anodizing, comprising an electrolytic cell; a lifting plate is provided inside the electrolytic cell, and fixed rods are movably sleeved at the four corners of the lifting plate, with the four fixed rods vertically fixed to the bottom wall of the electrolytic cell; a hydraulic cylinder is fixedly connected to the bottom of the electrolytic cell via a mounting bracket, and a connecting rod is fixedly connected to the output end of the hydraulic cylinder; the upper end of the connecting rod is inserted into the electrolytic cell and fixedly connected to the bottom end of the lifting plate; a support frame is provided at the upper end of the lifting plate, and a flexible clamp for holding aluminum profiles is fixedly connected to the upper end of the support frame; a buffer assembly is provided at the bottom of the flexible clamp.

[0006] Preferably, the buffer assembly includes a support block located at the upper center of the flexible clamp. The support block has mounting rods fixedly connected to both sides of its bottom end. Both mounting rods are movably sleeved with the upper end of the support frame. The bottom ends of both mounting rods are fixedly connected to bottom blocks. Springs are fixedly connected between the bottom blocks and the support frame. The two springs are respectively sleeved around the two mounting rods.

[0007] Preferably, a cushioning cotton is fixedly connected to the upper end of the support block.

[0008] Preferably, the support frame has openings on both sides of its bottom, and the upper end of the lifting plate is rotatably connected to two rotating shafts. The upper ends of the two rotating shafts are movably inserted into the openings, and the top ends of the two rotating shafts are fixedly connected to limit blocks. The bottom ends of the two limit blocks are tightly fitted to the inner wall of the support frame.

[0009] Preferably, the length of the limiting block is less than the opening length, the length of the limiting block is greater than the opening width, and the width of the limiting block is less than the opening width.

[0010] Compared with existing technologies, the hydraulic cylinder drives the connecting rod to raise and lower the lifting plate in the electrolytic cell, eliminating the need for manual placement of aluminum profiles deep into the electrolytic cell. This avoids collisions and friction between the aluminum profiles and the inner wall of the electrolytic cell caused by human error. At the same time, the aluminum profiles are held in place by flexible clamps to ensure their stability in the electrolytic cell, further ensuring their safety and preventing scratches, thus guaranteeing product quality.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-5 The present invention provides the following technical solution: Example 1: An anti-scratch device for aluminum profile anodizing, including an electrolytic cell 1; a lifting plate 2 is provided inside the electrolytic cell 1, and fixed rods 3 are movably sleeved at the four corners of the lifting plate 2. The four fixed rods 3 are vertically fixed to the bottom wall of the electrolytic cell 1. A hydraulic cylinder 5 is fixedly connected to the bottom of the electrolytic cell 1 through a mounting frame 4. A connecting rod 6 is fixedly connected to the output end of the hydraulic cylinder 5. The upper end of the connecting rod 6 is inserted into the electrolytic cell 1 and fixedly connected to the bottom end of the lifting plate 2; a support frame 8 is provided at the upper end of the lifting plate 2, and a flexible clamp 7 for clamping aluminum profiles is fixedly connected to the upper end of the support frame 8. The hydraulic cylinder 5 drives the connecting rod 6 to move the lifting plate 2 up and down in the electrolytic cell 1, so that it is not necessary to manually place the aluminum profiles deep into the electrolytic cell 1, avoiding the situation where the aluminum profiles collide and rub against the inner wall of the electrolytic cell 1 due to human error. The support frame 8 has openings 10 on both sides of its bottom. The upper end of the lifting plate 2 is rotatably connected to two rotating shafts 11. The upper ends of the two rotating shafts 11 are movably inserted into the openings 10. The top ends of the two rotating shafts 11 are fixedly connected to limit blocks 12. The bottom ends of the two limit blocks 12 are tightly fitted to the inner wall of the support frame 8. Rotating the rotating shafts 11 by 90 degrees makes the limit blocks 12 completely correspond to the openings 10. At this time, the restriction on the support frame 8 can be released, which makes it easier for workers to remove the support frame 8 and the flexible clamp 7 so that the aluminum profile on the flexible clamp 7 can be removed. The length of the limiting block 12 is less than the length of the opening 10, the length of the limiting block 12 is greater than the width of the opening 10, and the width of the limiting block 12 is less than the width of the opening 10. When the limiting block 12 is completely aligned with the opening 10, the restriction on the support frame 8 is released. When the limiting block 12 is not completely aligned with the opening 10, the bottom end of the limiting block 12 is tightly fitted with the inner wall of the support frame 8, thereby stably restricting the support frame 8 on the lifting plate 2, making the disassembly and assembly of the support frame 8 more convenient.

[0015] In use, the aluminum profile is clamped and fixed by the flexible clamp 7 to prevent it from moving or shaking in the electrolytic cell 1. Then, the hydraulic cylinder 5 is activated, and the hydraulic cylinder 5 pushes the lifting plate 2 up through the connecting rod 6. When the lifting plate 2 is raised to the opening of the electrolytic cell 1, the operator places the support frame 8 and the flexible clamp 7 on the lifting plate 2. The rotating shaft 11 and the limiting block 12 at the upper end of the lifting plate 2 pass through the opening 10 at the bottom of the support frame 8. The limiting block 12 is then manually rotated so that the two sides of the bottom end of the limiting block 12 are tightly fitted with the bottom wall of the support frame 8, thus completely positioning and installing the support frame 8. Finally, the hydraulic cylinder 5 is activated again, and the hydraulic cylinder 5 drives the lifting plate 2 to retract into the depth of the electrolytic cell 1 through the connecting rod 6. During the placement of the aluminum profile, the operator does not need to manually place the aluminum profile into the depth of the electrolytic cell 1, avoiding the collision and friction between the aluminum profile and the inner wall of the electrolytic cell 1 due to human error, thus ensuring the safety of the aluminum profile.

[0016] Example 2: Based on the technical solution of Example 1, this example further includes a buffer assembly 9. The buffer assembly 9 includes a support block 94, which is located at the center of the upper end of the flexible clamp 7. Mounting rods 93 are fixedly connected to both sides of the bottom end of the support block 94. Both mounting rods 93 are movably sleeved with the upper end of the support frame 8. Bottom blocks 91 are fixedly connected to the bottom ends of both mounting rods 93. Springs 92 are fixedly connected between the two bottom blocks 91 and the support frame 8. The two springs 92 are respectively sleeved around the two mounting rods 93. A buffer cotton 95 is fixedly connected to the upper end of the support block 94. During the process of clamping the aluminum profile by the flexible clamp 7, the bottom of the aluminum profile will be closely attached to the buffer cotton 95 at the upper end of the support block 94. The buffer cotton 95 supports and protects the aluminum profile to prevent scratches. When the support block 94 is subjected to force, it will push the mounting rod 93 to move down, thereby pushing the bottom block 91 to move down. During this process, the spring 92 will be stretched to form a vertical elastic buffer layer to absorb the impact force generated by the flow of electrolyte or equipment vibration, further ensuring the safety of the aluminum profile.
