Description

Technical Field

[0001] The present invention relates to the technical field of aluminum alloy processing, and particularly to an aluminum alloy surface treatment device and its use method. Background Art

[0002] Aluminum alloy is an alloy material based on aluminum and formed by adding other metals (such as copper, magnesium, zinc, silicon, etc.). During the production and processing of aluminum alloy, surface treatment is required. The surface treatment of aluminum alloy is a key step to improve its corrosion resistance, aesthetics and functionality. Among them, the degreasing treatment of aluminum alloy is one of the common aluminum alloy surface treatment processes, and the grease and pollutants on the surface of aluminum alloy are removed through specific processes.

[0003] The existing degreasing treatment of aluminum alloy surface mainly involves alkaline degreasing first. The aluminum alloy parts are immersed in an alkaline solution at 60 - 80 °C for 5 - 10 minutes, and the grease is decomposed through saponification reaction. Then, the aluminum alloy immersed for a certain period of time is taken out, and then cleaned with clean water and a brush to clean the residues and solution attached to its surface.

[0004] The deficiencies of the existing aluminum alloy surface treatment equipment are as follows: When the existing aluminum alloy surface treatment equipment performs degreasing treatment, although it can carry out alkali solution immersion and cleaning, during the surface cleaning treatment, generally only the workpiece is placed in flowing clean water, and then the workpiece is brushed with a brush. The workpiece itself is generally clamped by a rotating clamping member and rotated, that is, it contacts the brush in a rotating manner. However, the relative movement mode between the cleaning brush and the workpiece in this treatment method is relatively single, and the degree of movement is not intense enough, resulting in general cleaning effect and low cleaning efficiency.

The turntable is coaxially and fixedly connected to the corresponding connecting rotating shaft. A plurality of driving extrusion balls are arranged and circumferentially equidistantly distributed at the edge position of the turntable.

[0014] Preferably, the water flushing mechanism includes a bottom box and a vertical pipe. The bottom box is fixedly connected to the inner bottom of the cleaning tank. An auxiliary flushing mechanism is arranged between the bottom box and each elastic telescopic support member. The vertical pipe is perpendicularly and fixedly connected to the bottom box.

[0015] Preferably, the auxiliary flushing mechanism includes an auxiliary water pipe. A vertical auxiliary water pipe is fixedly connected to one side of the telescopic end of each elastic telescopic support member. A plurality of second spray holes are longitudinally and equidistantly formed on the auxiliary water pipe. A plurality of water outlet holes corresponding to and communicating with the auxiliary water pipes are formed on the outer wall of the bottom box.

[0016] Preferably, the movable sealing member includes a linkage vertical rod, a sealing sliding ring and a sealing block. The linkage vertical rod is vertically and slidably arranged in the vertical pipe. A linkage sealing plate is fixedly installed at the top of the linkage vertical rod. A transverse top plate cooperating with the linkage sealing plate is fixedly connected to the middle position of the movable ring. The sealing block is fixedly connected to the bottom of the linkage vertical rod. The sealing block is used for sealing the connection position between the bottom box and the vertical pipe. The sealing sliding ring is slidably arranged in the bottom box and is fixedly connected to the sealing block.

[0018] The using method of the aluminum alloy surface treatment equipment is as follows:

[0019] Step 1: First, clamp the aluminum alloy workpiece on the movable ring through the rotary clamping member;

[0020] Step 2: Drive the movable ring to horizontally move above the soaking tank through the driving and conveying mechanism, and then drive the movable ring to descend through the driving and conveying mechanism, so that the movable ring drives the clamped aluminum alloy workpiece to descend and immerse in the solution in the soaking tank;

[0023] The beneficial effects of the present invention:

[0024] 1. After the aluminum alloy workpiece after degreasing immersion treatment is transferred into the cleaning tank, the synchronous rotation of all connecting rotating shafts is achieved through the provided synchronous wheels and synchronous belts. The connecting rotating shafts drive the aluminum alloy workpieces clamped by the fixtures to rotate self - sufficiently, which is convenient for circumferential wiping and cleaning with the contacting cleaning brushes. At the same time, the connecting rotating shafts also drive the distributed active extrusion balls through the turntables to extrude the driven extrusion balls arranged on the lifting square tubes, so that the lifting square tubes move up and down continuously under the combined action of the spring resilience. In this way, the lifting square tubes drive the cleaning brushes to move longitudinally back and forth, which is convenient for effectively expanding the cleaning range. At the same time, due to the spring resilience acting each time, it is beneficial to the oscillation of the cleaning brushes, that is, various relative movement modes occur between the cleaning brushes and the workpieces, increasing the intensity of relative movement, thereby improving the cleaning effect and effectively removing the dirt adhering to the surface layer of the aluminum alloy workpieces.

[0025] 2. When the moving ring drives the clamped aluminum alloy workpiece to descend, the moving ring squeezes the linkage sealing plate through the horizontal top plate, realizing that the linkage sealing plate drives the linkage vertical rod to descend. The linkage vertical rod then drives the plugging block and the plugging sliding ring to descend, so that the water outlet holes on the bottom box and the connection positions of the vertical pipes with the bottom box are opened, facilitating the spraying of water and realizing the automatic start of the flushing function without separate control operations.

[0026] 3. When the water outlet holes of the bottom box are opened, it is convenient for the water flow to be diverted into each auxiliary water pipe, facilitating flushing the aluminum alloy workpiece from the side where the cleaning brushes are located. At the same time, the vertical pipes can flush the other side of the aluminum alloy workpiece, so as to effectively and fully flush the aluminum alloy workpiece, cooperate with the cleaning brushes for cleaning, and improve the overall surface cleaning effect.

[0038] The following describes the detailed implementation manners of the present invention in detail, but it should be understood that the protection scope of the present invention is not limited by the detailed implementation manners.

[0039] As Figures 1-9 shown, an aluminum alloy surface treatment device is used for degreasing the surface of the aluminum alloy workpiece 30. The treatment device includes a processing box 1, on which a soaking tank 2 and a cleaning tank 3 are horizontally arranged in sequence. The soaking tank 2 is used to hold the alkaline solution for degreasing treatment, and the aluminum alloy workpiece 30 is placed in it for soaking for a period of time. The cleaning tank 3 is used to rinse the aluminum alloy workpiece 30 with clean water after soaking for a certain time to further clean the aluminum alloy workpiece 30. A driving and conveying mechanism for driving the aluminum alloy workpiece 30 to lift or move horizontally is also provided on the processing box 1. It should be noted that the treatment device disclosed in the present invention is for long-strip aluminum alloy parts; the treatment device also includes a clamping driving mechanism and a reciprocating lifting brush mechanism;

[0040] The clamping driving mechanism includes a moving ring 6 and a rotating clamping part. The moving ring 6 is driven by the driving and conveying mechanism to perform lifting and horizontal movement. A plurality of groups of rotating clamping parts are provided and are circumferentially and equidistantly distributed on the moving ring 6. The rotating clamping parts are used to clamp and drive the aluminum alloy workpiece 30 to rotate;

[0041] There are multiple sets of reciprocating lifting brush mechanisms, which are circumferentially equidistantly distributed on the inner wall of the cleaning tank 3, and the reciprocating lifting brush mechanisms are correspondingly and cooperatively distributed with the rotary clamping members. An elevating drive mechanism is cooperatively arranged between each set of reciprocating lifting brush mechanisms and the corresponding rotary clamping member. During the rotation of the rotary clamping member, the rotary clamping member drives the reciprocating lifting brush mechanism to continuously perform elevating motion through the elevating drive mechanism. In this way, it is convenient to clean the aluminum alloy workpiece 30 during rotation. At the same time, the cleaning effect can be enhanced by relying on the elevating motion of the reciprocating lifting brush mechanism. A flushing mechanism is arranged in the cleaning tank 3 for flushing the aluminum alloy workpiece 30, and a drain pipe is distributed on one side of the bottom of the cleaning tank 3 to facilitate the discharge of the cleaning wastewater.

[0042] In some specific embodiments, as Figure 2 shown, each set of rotary clamping members includes a connecting rotating shaft 7 and a fixture. The connecting rotating shaft 7 is rotatably connected to the moving ring 6, and the connecting rotating shaft 7 longitudinally penetrates the moving ring 6. The fixture is installed at the bottom of the connecting rotating shaft 7. A synchronous drive mechanism for driving all the connecting rotating shafts 7 to rotate synchronously is arranged on the moving ring 6.

[0043] Among them, the synchronous drive mechanism includes a synchronous pulley 12 and a synchronous belt 13. A synchronous pulley 12 is coaxially and fixedly connected to the top of each connecting rotating shaft 7. The synchronous belt 13 is cooperatively connected to each synchronous pulley 12, that is, the synchronous belt 13 surrounds the distributed synchronous pulleys 12 and remains in a tensioned state. A drive motor 14 is fixedly installed on the moving ring 6 through a mounting seat, and the main shaft end of the drive motor 14 is fixedly connected to one of the synchronous pulleys 12.

[0044] In some other specific embodiments, the fixture includes clamping plates 9 and clamping adjustment members 8. A cross bar is fixedly connected to the bottom of each connecting rotating shaft 7. There are two clamping plates 9, which are respectively slidably arranged at both ends of the cross bar, that is, the cross bar penetrates the clamping plates 9. There are two groups of clamping adjustment members 8, which are distributed at both ends of the cross bar and are respectively used to drive the corresponding clamping plates 9 to move horizontally.

[0045] It should be noted that in some specific embodiments, the clamping adjustment member 8 can be an electric telescopic rod, so that one end of the electric telescopic rod is fixedly connected to the cross bar and the other end is correspondingly connected to the clamping plate 9; in some other specific embodiments, it can also be set as a screw. A fixing block threaded with the screw is installed at the end of the cross bar, and then the screw pushes against the clamping plate 9.

[0046] After each group of clamping plates 9 vertically fixes and clamps the aluminum alloy workpiece 30, the drive motor 14 is started. The drive motor 14 drives the connected synchronous pulley 12 to rotate. This synchronous pulley 12 drives all the other synchronous pulleys 12 to rotate through the synchronous belt 13, so as to realize the synchronous rotation of all the connecting rotating shafts 7. In this way, the aluminum alloy workpieces 30 clamped by each group of clamping plates 9 can be made to rotate self - rotatably.

[0047] In some specific embodiments, in combination with Figures 5-7 As shown, each reciprocating lifting brush mechanism includes an elastic telescopic support member and a cleaning brush 23. The elastic telescopic support member is vertically arranged inside the cleaning tank 3, and the cleaning brush 23 is arranged on the elastic telescopic support member.

[0048] Among them, the elastic telescopic support member includes a lifting square tube 15 and a support square rod 20. The support square rod 20 is vertically and fixedly connected to the inner bottom of the cleaning tank 3. The lifting square tube 15 is slidably sleeved on the support square rod 20. A compressible first spring 21 is also connected between the lifting square tube 15 and the corresponding support square rod 20. The lifting square tube 15 is driven by a lifting drive mechanism to perform a lifting motion. The cleaning brush 23 is adhered to the lifting square tube 15 and is on the side close to the rotary clamping member.

[0049] In some specific embodiments, in combination with Figure 2 and Figure 3 As shown, each lifting drive mechanism includes a turntable 10 and a driving extrusion ball 11. The turntable 10 is coaxially and fixedly connected to the corresponding connecting rotating shaft 7. A plurality of driving extrusion balls 11 are provided and are circumferentially and equidistantly distributed at the edge position of the turntable 10. A driven extrusion ball 16 that cooperates with the driving extrusion ball 11 is installed at the telescopic end of each elastic telescopic support member. The driven extrusion ball 16 can be fixedly connected to the top of the lifting square tube 15 of the elastic telescopic support member.

[0050] When the connecting rotating shaft 7 drives the clamped aluminum alloy workpiece 30 to rotate, the connecting rotating shaft 7 also drives the connected turntable 10 to rotate. At this time, the turntable 10 drives the distributed driving extrusion balls 11 to rotate. And at this time, the driven extrusion ball 16 at the top of the corresponding lifting square tube 15 is on the movement track of the driving extrusion ball 11. Therefore, when one of the driving extrusion balls 11 moves to the position where the driven extrusion ball 16 is located, an extrusion effect is generated. Relying on the spherical contact extrusion effect, it is convenient to make the lifting square tube 15 be subjected to a downward extrusion force and slide down along the support square rod 20, and compress the first spring 21. After the driving extrusion ball 16 that is extruding breaks away, the lifting square tube 15 can rise by the elastic force of the first spring 21. Repeating like this, the lifting square tube 15 can be continuously moved up and down, thereby driving the cleaning brush 23 to move up and down, facilitating longitudinal back-and-forth cleaning of the rotating aluminum alloy workpiece 30 and improving the cleaning effect.

[0051] In some specific embodiments, such as Figure 5As shown, the flushing mechanism includes a bottom box 19 and a vertical pipe 18. The bottom box 19 is fixedly connected to the inner bottom of the cleaning tank 3. The bottom box 19 is cylindrical, and the bottom of the bottom box 19 is externally connected to a water delivery pipe. An auxiliary flushing mechanism is provided between the bottom box 19 and each elastic telescopic support member. The vertical pipe 18 is vertically and fixedly connected to the bottom box 19 and the two are communicated. A plurality of groups of first spray holes are circumferentially formed on the vertical pipe 18. An active plugging member is also provided between the vertical pipe 18 and the bottom box 19.

[0052] Among them, as Figure 7 and Figure 8 shown, the auxiliary flushing mechanism includes an auxiliary water pipe 22. One side of the telescopic end of each elastic telescopic support member is vertically and fixedly connected with an auxiliary water pipe 22. A plurality of second spray holes for aligning with the aluminum alloy workpiece 30 are longitudinally and equidistantly formed on the auxiliary water pipe 22. It should be noted that the auxiliary water pipe 22 and the cleaning brush 23 can be reasonably distributed. For example, the auxiliary water pipe 22 is distributed in the middle, and the cleaning brushes 23 are distributed on both sides of the auxiliary water pipe 22. A plurality of water outlet holes 25 corresponding to and communicated with the auxiliary water pipes 22 are formed on the outer wall of the bottom box 19. Each water outlet hole 25 and the bottom of the corresponding auxiliary water pipe 22 are communicated through a hose.

[0053] In some specific implementation schemes, the active plugging member includes a linkage vertical rod 26, a plugging sliding ring 24 and a plugging block 28. The linkage vertical rod 26 is vertically slidably arranged in the vertical pipe 18, and the top of the linkage vertical rod 26 passes through the top of the vertical pipe 18. A linkage plugging plate 27 is fixedly installed at the top of the linkage vertical rod 26. A horizontal top plate 17 that cooperates with the linkage plugging plate 27 is fixedly connected to the middle position of the moving ring 6. The plugging block 28 is fixedly connected to the bottom of the linkage vertical rod 26. It should be noted that the inner diameter of the bottom box 19 is larger than the inner diameter of the vertical pipe 18, and the diameter of the plugging block 28 is smaller than the inner diameter of the bottom box 19 and larger than the diameter of the bottom of the vertical pipe 18. The plugging block 28 is used to plug the communication position between the bottom box 19 and the vertical pipe 18. The plugging sliding ring 24 is slidably arranged in the bottom box 19, and the plugging sliding ring 24 is fixedly connected to the plugging block 28 through a bracket. The outer diameter of the plugging sliding ring 24 is equal to the inner diameter of the bottom box 19. The plugging sliding ring 24 is used to plug the water outlet holes 25, and a compressible second spring 29 is connected between the plugging sliding ring 24 and the inner bottom of the bottom box 19.

[0054] Before the moving ring 6 descends into the cleaning tank 3 with the clamped aluminum alloy workpiece 30, the blocking block 28 blocks the connection position between the bottom box 19 and the vertical pipe 18, and the blocking slip ring 24 blocks the water outlet holes 25 distributed on the bottom box 19. At this time, the water source driving end of the external water pipe has been opened. When the moving ring 6 moves to the top of the cleaning tank 3 and descends, it drives the horizontal top plate 17 to descend, and the horizontal top plate 17 descends and squeezes onto the linkage blocking plate 27, pushing the linkage blocking plate 27 to descend and block the top of the vertical pipe 18. At the same time, the linkage blocking plate 27 drives the blocking plate 27 to move through the linkage vertical rod 26. The block 28 descends, thereby allowing the vertical pipe 18 and the bottom box 19 to be connected. At the same time, the blocking block 28 also drives the blocking slip ring 24 to slide down, so that the water outlet 25 is opened. In this way, the water injected into the bottom box 19 is diverted into each auxiliary water pipe 22 through the water outlet 25, so that it is convenient to spray to one side of the aluminum alloy workpiece 30 through the second spray hole on the auxiliary water pipe 22, and cooperate with the cleaning brush 23 to facilitate close cleaning of the aluminum alloy workpiece 30; at the same time, the water flow also enters the vertical pipe 18, is sprayed out through the first spray hole distributed on the vertical pipe 18, and is flushed from the other side of the aluminum alloy workpiece 30 to ensure the cleaning effect.

[0055] In some specific embodiments, such as Figure 1 As shown, the driving and conveying mechanism includes an electric guide rail 5 and a hydraulic telescopic rod 4. Two groups of hydraulic telescopic rods 4 are provided and are fixedly arranged on both sides of the processing box 1 respectively. Two groups of electric guide rails 5 are provided and are fixedly installed on the telescopic ends of the hydraulic telescopic rod 4 respectively. The moving ring 6 is slidably connected to the electric guide rail 5. The hydraulic telescopic rod 4 is extended and retracted to realize the lifting and lowering of the moving ring 6 with the aluminum alloy workpiece 30, and the moving ring 6 is moved laterally along the electric guide rail 5.

[0056] The specific steps of using the above-mentioned aluminum alloy surface treatment equipment are as follows:

[0057] The first step is to clamp the aluminum alloy workpiece 30 on the movable ring 6 by a rotating clamp;

[0058] Step 2: The conveying mechanism is driven to move the movable ring 6 horizontally to the top of the immersion tank 2, and then the conveying mechanism is driven to lower the movable ring 6, so that the movable ring 6 drives the clamped aluminum alloy workpiece 30 to descend and immerse it in the solution in the immersion tank 2;

[0059] Step 3: After the soaking reaches the set time, the conveying mechanism is driven to lift the movable ring 6, and the movable ring 6 is driven to move to the top of the cleaning tank 3, and then the conveyor is driven to lower the movable ring 6, so that the aluminum alloy workpiece 30 is lowered into the cleaning tank 3;

[0060] Step 4: The aluminum alloy workpiece 30 is rotated by rotating the clamping member to release it from the corresponding reciprocating lifting brush mechanism, and the aluminum alloy workpiece 30 is flushed by the flushing mechanism.

[0061] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in conjunction with specific application scenarios:

[0062] First, the aluminum alloy workpieces 30 are vertically fixed and clamped by the groups of clamping plates 9 distributed on the movable ring 6; the clamped aluminum alloy workpieces 30 are lowered and immersed in the solution in the immersion tank 2 for a period of time, and then raised and moved to the cleaning tank 3. When the movable ring 6 lowers the clamped aluminum alloy workpieces 30 into the cleaning tank 3, each aluminum alloy workpiece 30 just contacts the corresponding cleaning brush 23, and at this time, the active squeezing ball 11 on the corresponding turntable 10 cooperates with the corresponding driven squeezing ball 16;

[0063] The top plate 17 is moved downwards to press against the linkage blocking plate 27, thereby pushing the linkage blocking plate 27 down to block the top of the vertical pipe 18. At the same time, the linkage blocking plate 27 drives the blocking block 28 to move downwards through the linkage vertical rod 26, thereby making the vertical pipe 18 and the bottom box 19 communicate with each other. At the same time, the blocking block 28 also drives the blocking sliding ring 24 to move downwards, thereby opening the water outlet 25. The water injected into the bottom box 19 is diverted into each auxiliary water pipe 22 through the water outlet 25, so that it can be sprayed toward one side of the aluminum alloy workpiece 30 through the second spray hole on the auxiliary water pipe 22, and cooperates with the cleaning brush 23 to facilitate the close cleaning of the aluminum alloy workpiece 30. At the same time, the water flow also enters the vertical pipe 18, is sprayed out from the other side of the aluminum alloy workpiece 30 through the first spray hole distributed on the vertical pipe 18, and ensures the cleaning effect.

[0064] At the same time, the drive motor 14 is started, and the drive motor 14 drives the connected synchronous wheel 12 to rotate, and the synchronous wheel 12 drives all other synchronous wheels 12 to rotate through the synchronous belt 13, thereby realizing the synchronous rotation of all the connected rotating shafts 7, so that the aluminum alloy workpieces 30 clamped by each group of clamping plates 9 can rotate on their own; in this way, each aluminum alloy workpiece 30 rubs against the corresponding cleaning brush 23 to achieve cleaning and scrubbing;

[0065] When the connecting shaft 7 drives the clamped aluminum alloy workpiece 30 to rotate, the connecting shaft 7 also drives the connected turntable 10 to rotate. At this time, the turntable 10 drives the distributed active squeezing balls 11 to rotate, and at this time, the driven squeezing balls 16 on the top of the corresponding lifting square tube 15 are on the movement trajectory of the active squeezing balls 11. Therefore, when one of the active squeezing balls 11 moves to the position of the driven squeezing balls 16, an squeezing effect is generated. Relying on the spherical contact squeezing effect, the lifting square tube 15 is subjected to a downward squeezing force and slides down along the supporting square rod 20, and compresses the first spring 21. After the squeezed active squeezing balls 11 are detached, the lifting square tube 15 can be raised by the elastic force of the first spring 21. Repeatedly, the lifting square tube 15 can be continuously moved up and down, thereby driving the cleaning brush 23 to move up and down, which is convenient for cleaning the rotating aluminum alloy workpiece 30 back and forth longitudinally and improving the cleaning effect.

[0066] The above disclosures are only a few specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
