Description

Technical Field

[0001] This invention relates to the field of aluminum plate pickling technology, and more specifically to a double-sided, all-around pickling device for aluminum plates. Background Technology

[0002] To remove oxides and impurities from the surface of aluminum plates, improve surface quality, enhance coating adhesion, and prepare for subsequent processing, aluminum plates generally require pickling due to their high surface quality requirements. Pickling is usually carried out after the aluminum plate has been quenched. In the pickling process, the aluminum plate is first placed in a pickling tank for pickling, and then transferred to a cold water tank for rinsing to complete the pickling process.

[0003] When existing pickling equipment pickles multiple aluminum plates simultaneously, if two adjacent aluminum plates are stacked too densely or overlapped in the tank, the pickling speed at the contact surface will be slower than that at the exposed surface due to poor acid flow, thus affecting the uniformity of pickling. Furthermore, fixing the position of the aluminum plates (usually the position where the hook or clamp contacts the aluminum plate) will make it difficult for the acid to penetrate, thus affecting the overall pickling quality of the aluminum plates. To address these issues, existing equipment needs to be improved. Summary of the Invention

[0004] The purpose of this invention is to provide a double-sided all-round pickling device for aluminum plates. Through a unique design, a positioning component is set in the pickling tank, and a flip-up clamping component is set on the positioning component. The clamping component is used to fix the aluminum plate. During the pickling process, a part of the aluminum plate is first put into the acid solution in the pickling tank, and after the pickling is completed, the other part is put into the acid solution in the pickling tank to achieve all-round pickling and improve the quality of pickling.

[0015] Preferably, a third electric telescopic column is symmetrically fixed on both sides of the bottom of the pickling tank, and a top support block is fixed on the top of the third electric telescopic column, with the toothed plate resting on the top support block.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This double-sided, all-around pickling device for aluminum plates can achieve adjustable spacing and all-around pickling. Before installing the clamping and flipping mechanism, the toothed plate and top support block need to be lowered. When installing the clamping and flipping mechanism, the first slider needs to be slid into the groove. Multiple clamping and flipping mechanisms can be installed in the pickling tank, and the spacing between two adjacent clamping and flipping mechanisms is adjustable to avoid adjacent aluminum plates being stacked too densely or overlapping in the pickling tank, which would cause poor acid flow. After fixing the clamping and flipping mechanism, the toothed plate and top support block are raised. The top support block always supports the toothed plate. The toothed plate is engaged with the toothed ring. After completing the pickling treatment of one part of the aluminum plate, the toothed plate moves forward, driving all the toothed rings and rotating shafts to rotate. All the positioning frames are flipped 180 degrees. Then, the other part of the aluminum plate can be pickled, which can achieve all-around pickling and improve the quality of pickling.

[0017] 2. This double-sided, all-around pickling device for aluminum plates achieves the goal of clamping without affecting full and comprehensive penetration. Each pair of positioning frames forms a group, used to clamp one aluminum plate. Before loading, the pallet can be raised. During loading, the aluminum plate is placed between the two positioning frames and rests on the pallet, with the central axis of the aluminum plate coinciding with the central axis of the positioning frames. As the upper moving plate moves to the right, the lower moving plate moves to the left. The movement of the moving plates drives the gears and lead screw to rotate. The upper front and rear third sleeves move closer together, and with the use of clamping blocks, the aluminum plate is clamped and fixed. Simultaneously, the lower front and rear third sleeves move further apart. Before flipping the aluminum plate, the pallet is lowered, the upper moving plate remains stationary, and the lower moving plate moves to the right. After unlocking the upper moving plate, the moving plate automatically moves to the left, allowing for alternating clamping of the two parts of the aluminum plate. The aluminum plate can then be flipped 180 degrees. Throughout the pickling process, the clamping blocks immersed in the acid will not contact the aluminum plate, eliminating dead angles and ensuring full and comprehensive acid penetration.

[0018] 3. This double-sided all-round pickling device for aluminum plates can achieve the purpose of adjusting the clamping degree according to the thickness of the aluminum plate. Before clamping the aluminum plate, the position of the moving frame can be adjusted to facilitate the adjustment of the distance between the locking block and the pressing block according to the thickness of the aluminum plate. When the moving plate moves to the right, the pressing block presses the locking block and the moving block in turn. The moving plate is finally locked by the locking block, and the clamping action is completed at this time. Attached Figure Description

The first bolt 506 is threaded into one of the threaded holes 4 in the inner wall of the pickling tank 1. When installing the clamping and flipping mechanism 5, the first slider 501 needs to be slid into the slide groove 3. After adjusting the position of the clamping and flipping mechanism 5, the first bolt 506 can be screwed into the corresponding threaded hole 4 to fix the clamping and flipping mechanism 5. Each clamping and flipping mechanism 5 can be used to clamp an aluminum plate.

[0026] In this embodiment, as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 10 and Figure 11 As shown, an adjustment mechanism 507 is fixed to the outer end face of the positioning frame 503.

The movable frame 5072 can move under the extension and retraction of the first electric telescopic rod 5071, which facilitates adjusting the position of the movable frame 5072 according to the thickness of the aluminum plate. The first connecting pipe 50712 serves to connect the second cylinder 5078 and the first cylinder 5074. When the locking block 5077 and the first piston 5076 are squeezed and moved, the corresponding second piston 50710 and the movable block 50711 move to the right. When the movable block 50711 is squeezed and moves to the right, it will drive the second piston 50710 to move to the right. The corresponding first piston 5076 will move under the action of oil pressure, and the corresponding locking block 5077 will move.

[0027] In this embodiment, as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, two third hydraulic cylinders 508 are fixed to the outer end face of the positioning frame 503, and a second connecting pipe 518 is fixed between the two third hydraulic cylinders 508. A third piston 509 is slidably connected inside the third hydraulic cylinder 508, and a movable rod 510 is fixed to one side of the third piston 509. The movable rod 510 passes through one end of the third hydraulic cylinder 508. A second electric telescopic rod 511 is fixed to one of the third hydraulic cylinders 508 on the positioning frame 503, and a corresponding movable rod 510 is fixed to one end of the second electric telescopic rod 511. The second connecting pipe 518 serves to connect the two third hydraulic cylinders 508 on the same positioning frame 503. The extension and retraction of the second electric telescopic rod 511 will drive the corresponding movable rod 510 and the third piston 509 to move. The movement directions of the third pistons 509 in the two third hydraulic cylinders 508 on the same positioning frame 503 are opposite.

[0028] In this embodiment, as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a first sleeve 512 is fixed to the other side of the third piston 509, and the first sleeve 512 passes through the other end of the third cylinder 508. A third spring 513 is fixed inside the first sleeve 512, and a second slider 514 is fixed to one end of the third spring 513. The second slider 514 is slidably connected inside the first sleeve 512, and a moving plate 515 is fixed to one side of the second slider 514. A rack 516 is fixed to the inner end face of the moving plate 515, and a pressing block 517 is fixed to one end of the moving plate 515. A groove is opened on the outer end face of the moving plate 515. When the third piston 509 moves to the right, it can drive the first sleeve 512 to the right. When the movement is initiated, the corresponding second slider 514, moving plate 515, and pressing block 517 move to the right as a whole, and locking block 5077 moves upward. When locking block 5077 aligns with the slot, it will automatically spring into the slot under the action of the first spring 5075, which will help lock the moving plate 515. When the third piston 509 moves to the left, the moving plate 515 is locked in place. At this time, the third spring 513 is stretched. After unlocking the moving plate 515, the moving plate 515 and the second slider 514 move to the left automatically under the action of the third spring 513. When the rack 516 moves left and right with the moving plate 515, it can drive the related components to rotate.

[0029] In this embodiment, as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 9As shown, the outer end of the second sleeve 519 is rotatably connected to a lead screw 520, and the outer end of the lead screw 520 is fixed with a gear 521. The gear 521 is meshed with the rack 516. The third sleeve 522 is threaded to the outside of the lead screw 520. When the rack 516 moves left and right with the moving plate 515, it will drive the gear 521 to rotate, thereby driving the lead screw 520 to rotate. At this time, the third sleeve 522 can slide forward or backward under the limiting action of the second sleeve 519 and the lead screw 520. The front and rear third sleeves 522 move closer or further apart from each other. When used with a clamping block 523, the aluminum plate can be clamped or released.

[0030] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, a limiting rod 6 is fixed inside the slide 3, and the limiting rod 6 passes through the first slider 501. A pull block 7 passes through the front side of the pickling tank 1, and the pull block 7 is fixed to the pickling tank 1 by the second bolt 8. A stop rod 9 is fixed to the rear side of the pull block 7, and the stop rod 9 is engaged with the front end of the limiting rod 6. Before installing the clamping and flipping mechanism 5, the pull block 7 needs to be held and the stop rod 9 needs to be pulled forward to make it leave the slide 3. After completing the installation of the corresponding number of clamping and flipping mechanisms 5 as required, the pull block 7 is pushed backward and the stop rod 9 is engaged with the limiting rod 6 to seal the entrance of the slide 3. Then the pull block 7 can be fixed by the second bolt 8. The slide 3 and the limiting rod 6 play a limiting role during the sliding of the first slider 501.

[0031] In this embodiment, as Figure 4 As shown, a first electric telescopic column 10 is fixed at the middle of the bottom of the pickling tank 1, and a support plate 11 is fixed at the top of the first electric telescopic column 10. The support plate 11 can move up and down under the telescopic action of the first electric telescopic column 10, so that the height of the support plate 11 can be adjusted according to the size of the aluminum plate. When loading, the aluminum plate can be placed between the two positioning frames 503 and placed on the support plate 11.

[0032] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a third electric telescopic column 15 is symmetrically fixed on both sides of the bottom of the pickling tank 1, and a top support block 16 is fixed on the top of the third electric telescopic column 15. The toothed plate 14 rests on the top support block 16. Before installing the clamping and flipping mechanism 5, the toothed plate 14 and the top support block 16 need to be lowered first. After completing the installation and fixing operation of the clamping and flipping mechanism 5, the toothed plate 14 and the top support block 16 are raised and the toothed plate 14 is meshed with the toothed ring 504. The top support block 16 plays a supporting role for the toothed plate 14.

[0033] The method of use and advantages of this invention: The working process of this double-sided, all-around pickling device for aluminum plates is as follows: like Figures 1 to 11As shown: When connected to an external power source, first, hold the pull block 7 and pull the stop bar 9 forward to move it away from the slide groove 3. After lowering the toothed plate 14 and the top support block 16, slide the first slider 501 into the slide groove 3. Multiple clamping and flipping mechanisms 5 can be installed in the pickling tank 1. The number of clamping and flipping mechanisms 5 can be installed according to the needs. Next, push the pull block 7 backward and engage the stop bar 9 with the limit rod 6 to seal the entrance of the slide groove 3. Then, use the second bolt 8 to fix the pull block 7. The spacing between two adjacent clamping and flipping mechanisms 5 is adjustable. After adjusting the position of each clamping and flipping mechanism 5 by holding the handle 505, screw the first bolt 506 into the corresponding threaded hole 4 to lock the handle 505. The first electric telescopic rod 5071 extends and retracts to move the slide groove 3. The moving frame 5072 moves left and right to facilitate adjustment of its position according to the size of the aluminum plate. Two positioning frames 503 are grouped together, and each pair of positioning frames 503 can hold one aluminum plate. Before loading, the height of the pallet 11 can be adjusted. The aluminum plate is placed between two positioning frames 503 and rests on the pallet 11, with the horizontal central axis of the aluminum plate coinciding with the horizontal central axis of the positioning frames 503. Then, the toothed plate 14 and the top support block 16 are raised, and the toothed plate 14 is engaged with all the toothed rings 504. Next, the second electric telescopic rod 511 retracts, thereby driving the corresponding moving rod 510 and the third piston 509 to move to the right. The corresponding first sleeve 512, moving plate 515, and pressing block 517 move to the right as a whole, and the pressing block 517 presses sequentially. Locking block 5077 and movable block 50711. Locking block 5077 eventually engages with the slot of movable plate 515, thus locking movable plate 515. When movable plate 515 moves to the right, it drives the corresponding gear 521 to rotate. At the same time, the third piston 509 in the lower third cylinder 508 moves to the left, and the corresponding movable plate 515 moves to the left, thereby driving the corresponding gear 521 to rotate. The upper and lower gears 521 rotate in opposite directions. The rotation of gear 521 drives the lead screw 520 to rotate, thereby driving the third sleeve 522 to move forward or backward. The upper front and rear third sleeves 522 move closer to each other, and with the use of clamping block 523, they can clamp and fix the aluminum plate. The lower front and rear third sleeves 522 move further apart, making it easier to release the aluminum plate. The corresponding clamping block 523 does not contact the aluminum plate, completing the clamping process. After the operation, the support plate 11 is lowered, and acid is then introduced into the pickling tank 1 until it reaches half of the aluminum plate. After a portion of the aluminum plate has been pickled, the second electric telescopic rod 511 extends, thereby driving the corresponding movable rod 510 and the third piston 509 to move to the left. The upper movable plate 515 is locked, the third spring 513 is stretched, and the lower third piston 509, the first sleeve 512, the movable plate 515, and the pressing block 517 move to the right as a whole. The pressing block 517 presses the corresponding locking block 5077 and the movable block 50711 in sequence, unlocking the upper movable plate 515. The upper second slider 514, the movable plate 515, and the pressing block 517 automatically move to the left. After the lower third sleeve 522 and the clamping block 523 have firmly clamped the aluminum plate,The third sleeve 522 and clamping block 523 on the upper side then release the aluminum plate, thus achieving alternating clamping from top to bottom. Afterwards, the third electric telescopic rod 13 extends, driving the toothed plate 14 to move, thereby rotating all the toothed rings 504 and the rotating shaft 502. All the positioning frames 503 rotate 180 degrees, immersing the other part of the aluminum plate in the acid solution. Throughout the pickling process, the clamping block 523 immersed in the acid solution does not contact the aluminum plate, ensuring full and complete penetration of the acid solution while clamping. After completing the pickling operation, the support plate 11 is raised to support the aluminum plate. One of the moving plates 515 and the pressing block 517 moves to the right but not to the bottom. At this time, neither the upper nor lower parts of the aluminum plate are clamped. The aluminum plate can then be pulled out upwards, and the electric drain valve 2 can be opened to drain the acid solution.
