Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy processing technology, specifically to a device for removing oxide scale from the surface of aluminum alloys. Background Technology

[0002] Aluminum alloys are lightweight metal materials formed by adding other alloying elements to aluminum as the base material. They have characteristics such as low density, high strength, corrosion resistance, and easy processing, and are widely used in aerospace, transportation, construction, electronics and other fields. The removal of oxide scale on the surface of aluminum alloys is a key step in metal surface treatment, which directly affects the quality of subsequent processing and product performance.

[0003] Currently, during the production and processing of aluminum alloys, a layer of oxide scale forms on the surface. This scale is typically removed by immersion in chemical solutions. The scale gradually detaches from the aluminum alloy surface and deposits in the solution within the immersion chamber. As the scale accumulates, it negatively impacts the quality of the solution, significantly shortening its lifespan. Existing aluminum alloy descaling equipment largely lacks effective automated cleaning methods for removing the scale from the immersion chamber. It usually requires periodic manual shutdowns and cumbersome cleaning methods, which are not only labor-intensive and inefficient but also fail to provide real-time scale removal, further reducing production efficiency. Utility Model Content

[0019] 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.

[0020] In the embodiments, by Figure 1-4 A device for removing oxide scale from aluminum alloy surfaces is provided, comprising a base 1, a housing 2 fixedly mounted on the top of the base 1, a moving component 3 disposed at the top of the housing 2, a telescopic cylinder 4 disposed on the moving component 3, a mounting frame 5 fixedly mounted on the telescopic end of the telescopic cylinder 4, push rods 6 fixedly mounted on the left and right sides of the bottom of the mounting frame 5, a gripper 7 disposed between the two push rods 6, an immersion chamber 8 fixedly mounted on the base 1, mounting plates 9 fixedly mounted on the front and rear sides of the immersion chamber 8, a tensioning component 10 disposed between the two mounting plates 9, a net 11 disposed on the outer side of the tensioning component 10, a driving component 12 disposed between the two mounting plates 9 for moving the net 11, a collection chamber 13 located at the bottom of the net 11 fixedly mounted on the bottom of the base 1, and a cleaning component 14 disposed on the side of the immersion chamber 8.

[0021] Reference Figure 2 The movable component 3 includes a movable groove 31. The movable groove 31 is opened at the top of the inside of the housing 2. A reduction motor 32 is fixedly installed inside the movable groove 31. A lead screw 33 is fixedly connected to the output end of the reduction motor 32. The lead screw 33 is rotatably installed inside the movable groove 31. A lead screw slider 34 is threadedly connected to the lead screw 33. A telescopic cylinder 4 is fixedly installed at the bottom of the lead screw slider 34.

[0022] With the above structural setup, after the gripper 7 clamps the aluminum alloy, the reduction motor 32 is started. The reduction motor 32 drives the lead screw 33 to rotate. While the lead screw 33 is rotating, it drives the lead screw slider 34 to move back and forth in the moving groove 31. While the lead screw slider 34 is moving, it drives the telescopic cylinder 4 to move.

[0023] Reference Figure 1-4 The tensioning assembly 10 includes a double-headed telescopic rod 101. The double-headed telescopic rod 101 is fixedly installed on the mounting plate 9. The mounting plate 9 has symmetrical sliding grooves 102. Sliding blocks 103 are fixedly installed inside the sliding grooves 102. The two sliding blocks 103 on both sides are respectively connected to the telescopic ends of the double-headed telescopic rod 101. Tensioning wheels 104 are rotatably installed on the sliding blocks 103.

[0024] With the above-mentioned structural design, when the oxide scale on the aluminum alloy falls off and into the soaking chamber 8, the double-headed telescopic rod 101 is activated. The double-headed telescopic rod 101 simultaneously drives the sliding blocks 103 on both sides to move along the sliding groove 102, so that the tensioning wheels 104 on both sides support the net 11 and retrieve the oxide scale from the soaking chamber 8, thus avoiding a large amount of oxide scale remaining in the solution and extending the service life of the solution in the soaking chamber 8.

[0025] Reference Figure 1-4 The drive assembly 12 includes mounting rollers 121. Mounting rollers 121 are rotatably mounted inside the base 1 on both sides of the soaking chamber 8. The two mounting rollers 121 are connected by a pulley group 122. A drive motor 123 for driving the pulley group 122 to move is fixedly mounted inside the base 1.

[0026] With the above-mentioned structural setup, after the tensioning assembly 10 tightens and retrieves the net 11 from the solution, the drive motor 123 is started. The drive motor 123 drives the two mounting rollers 121 to rotate synchronously through the pulley group 122, causing the net 11 to move to one side. The oxide scale on the net 11 moves with it and falls off the net 11 into the collection bin 13 for storage, making it convenient for workers to recycle the oxide scale later.

[0027] Reference Figure 2 The cleaning assembly 14 includes a cleaning chamber 141. The cleaning chamber 141 located on the side of the soaking chamber 8 is fixedly installed inside the base 1. Several nozzles 142 are arranged in a ring inside the cleaning chamber 141. The nozzles 142 are connected to the water pump 144 through the water supply pipe 143.

[0028] With the above structural design, most of the oxide scale will fall off after the aluminum alloy is soaked in the solution. However, some residue will still adhere to the surface of the aluminum alloy. When the aluminum alloy enters the cleaning chamber 141, the water pump 144 is started. The water pump 144 draws water from the outside and delivers it to the nozzle 142 through the water pipe 143 to rinse the aluminum alloy, remove the residual deposits and solution, and ensure the cleanliness of the aluminum alloy.

[0029] The implementation process of this utility model is as follows:

[0030] Step 1: After the gripper 7 clamps the aluminum alloy, start the reduction motor 32. The reduction motor 32 drives the lead screw 33 to rotate. While the lead screw 33 is rotating, it drives the lead screw slider 34 to move back and forth in the moving groove 31. While the lead screw slider 34 is moving, it drives the telescopic cylinder 4 to move. After the telescopic cylinder 4 moves to the top of the soaking chamber 8, the telescopic cylinder 4 drives the mounting bracket 5 to move downward. During the movement, the push rods 6 on both sides will press the net 11 back into the soaking chamber 8. At the same time, the gripper 7 holds the aluminum alloy and immerses it in the solution in the soaking chamber 8. When the oxide scale on the aluminum alloy undergoes a chemical reaction in the alkaline solution, soluble aluminates are generated, which weakens the bonding force between the oxide scale and the substrate. During the reaction, the oxide scale will gradually peel off in layers, appearing as blocks or flakes. After soaking, the aluminum alloy is moved to the top of the cleaning chamber 141.

[0031] Step 2: After the oxide scale on the aluminum alloy falls off and into the soaking chamber 8, the double-headed telescopic rod 101 is activated. The double-headed telescopic rod 101 simultaneously drives the sliding blocks 103 on both sides to move along the sliding groove 102, so that the tensioning wheels 104 on both sides support the net 11 and retrieve the oxide scale from the soaking chamber 8. After the tensioning assembly 10 tightens the net 11 from the solution, the drive motor 123 is activated. The drive motor 123 drives the two mounting rollers 121 to rotate synchronously through the pulley group 122, so that the net 11 moves to one side. The oxide scale on the net 11 moves with it and falls off the net 11 into the collection bin 13 for storage. After the oxide scale on the net 11 is cleaned, the drive motor 123 is turned off. At the same time, the double-headed telescopic rod 101 drives the sliding blocks 103 on both sides to retract, so that the tensioning wheels 104 release the net 11 from the fixation. When processing new aluminum alloy, the push rod 6 will press the net 11 back into the soaking chamber 8.

[0032] Step 3: After the aluminum alloy enters the cleaning chamber 141, the water pump 144 is started. The water pump 144 draws water from the outside and delivers it to the nozzle 142 through the water pipe 143 to rinse the aluminum alloy, remove residual deposits and solution, and ensure the cleanliness of the aluminum alloy.
