Technical Field

[0001] This utility model relates to the field of metal processing equipment technology, specifically to a bending and forming device for producing thin-walled pure aluminum plates. Background Technology

[0002] Thin-walled pure aluminum sheets are widely used in aerospace, automotive manufacturing, and electronic equipment industries due to their advantages such as light weight, good thermal conductivity, and strong corrosion resistance. In practical applications, bending forming equipment is often used to bend thin-walled pure aluminum sheets into specific shapes to meet different assembly requirements.

[0003] However, the forming block, bending plate and worktable in the existing bending forming device are designed as an integrated unit, which makes it impossible to adjust the size and shape of the forming block and bending plate. This limits its applicability to bending thin-walled pure aluminum plates of a single size and shape.

[0004] To address this, a bending forming device for producing thin-walled pure aluminum plates is proposed. Summary of the Invention

[0005] The purpose of this utility model is to provide a bending and forming device for producing thin-walled pure aluminum plates.

[0008] Preferably, a perforation is provided on the inner wall of the other side of the movable cavity, and a locking rod is fixed at the end of the movable plate away from the threaded rod, passing through the perforation and located inside the locking hole.

[0009] Preferably, the connector includes a receiving block fixed to one end of the electric push cylinder, and a receiving frame is sleeved on the outside of the receiving block, and the receiving frame is fixed to one end of the bending plate. The top of the receiving block is provided with a connecting groove; The inner walls on both sides of the connecting groove are respectively provided with a first limiting hole and a second limiting hole, and the inner walls on both sides of the receiving frame are respectively provided with a third limiting hole and a fourth limiting hole.

[0010] Preferably, a telescopic rod is provided in the connecting groove, and a first connecting plate and a second connecting plate are respectively fixed at both ends of the telescopic rod. The ends of the first connecting plate and the second connecting plate that are far apart from each other are respectively fixed with a first locking post located inside the first limiting hole and the third limiting hole, and a second locking post located inside the second limiting hole and the fourth limiting hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model utilizes a rotating column to drive a threaded rod to move within a threaded hole. As the threaded rod moves, it causes a movable plate to move within the movable cavity of the connecting block. As the movable plate moves, it causes a locking rod to move within a through hole. Once one end of the locking rod disengages from the locking hole, the fixing of the molding block can be released, allowing the molding block to be replaced. The first connecting plate and the second connecting plate drive the telescopic rod and the spring to retract. At this time, the first connecting plate and the second connecting plate will move closer to each other. When the first locking pin disengages from the first limiting hole and the third limiting hole, and the second locking pin disengages from the second limiting hole and the fourth limiting hole, the fixing of the bending plate can be released, and the bending plate can be replaced.

The movable plate 20, at the end furthest from the threaded rod 25, is fixed with a locking rod 22 that passes through the through hole 21 and is located inside the locking hole 23. The connecting component includes a receiving block 5 fixed to one end of the electric push cylinder 3. A receiving frame 6 is sleeved on the outside of the receiving block 5 and fixed to one end of the bent plate 4. A connecting groove 7 is formed on the top of the receiving block 5. A first limiting hole 8 and a second limiting hole 9 are respectively formed on the inner walls of both sides of the connecting groove 7. A third limiting hole 10 and a fourth limiting hole 11 are respectively formed on the inner walls of both sides of the receiving frame 6. A telescopic rod 12 is provided in the groove 7.

A first locking post 15 located inside the first limiting hole 8 and the third limiting hole 10, and a second locking post 16 located inside the second limiting hole 9 and the fourth limiting hole 11 are fixed at the ends of the first connecting plate 13 and the second connecting plate 14, respectively. A spring 17 is provided on the outside of the telescopic rod 12. Both ends of the spring 17 are fixed to the first connecting plate 13 and the second connecting plate 14, respectively.

[0019] Specifically, this utility model uses a rotating column 26 to drive a threaded rod 25 to move within a threaded hole 24. When the threaded rod 25 moves, it drives a movable plate 20 to move within a movable cavity 19 of a connecting block 18. When the movable plate 20 moves, it drives a locking rod 22 to move within a through hole 21. When one end of the locking rod 22 disengages from the locking hole 23, the fixing of the molding block 2 can be released, and the molding block 2 can be replaced.

When the first locking pin 15 disengages from the first limiting hole 8 and the third limiting hole 10 and the second locking pin 16 disengages from the second limiting hole 9 and the fourth limiting hole 11, the fixing of the bending plate 4 can be released, and the bending plate 4 can be replaced. In summary, by changing the fixing method of the forming block 2 and the bending plate 4, this utility model makes it easy to flexibly replace the forming block 2 and the bending plate 4, so that the forming block 2 and the bending plate 4 can be used for bending and forming thin-walled pure aluminum plates of different sizes and shapes, and has good applicability. Example

[0020] Please see Figure 1 This utility model provides a technical solution: a bending forming device for producing thin-walled pure aluminum plates, wherein a U-shaped strip 27 is fixed on the outer wall of the forming block 2, a motor 28 is installed at one end of the U-shaped strip 27, and a bidirectional lead screw 29 is connected to the output end of the motor 28 with a coupling; two lead screw nuts 30 are installed on the outer wall of the bidirectional lead screw 29, and limit strips 31 are fixed on the outer wall of both lead screw nuts 30, and the two lead screw nuts 30 are respectively installed in two different thread areas of the bidirectional lead screw 29.

[0021] Specifically, before bending the thin-walled pure aluminum sheet, the motor 28 is started. The motor 28 drives the bidirectional lead screw 29 to work. Under the drive of the bidirectional lead screw 29, the two lead screw nuts 30 drive the two limiting strips 31 to move in opposite directions. When the two limiting strips 31 come into contact with the thin-walled pure aluminum sheet, they can limit the thin-walled pure aluminum sheet, thereby ensuring the bending and forming effect of the thin-walled pure aluminum sheet.

[0022] Working principle: First, the thin-walled pure aluminum plate is attached to the forming block 2. Then, the motor 28 is started. The motor 28 will drive the bidirectional lead screw 29 to work. Under the drive of the bidirectional lead screw 29, the two lead screw nuts 30 will drive the two limit strips 31 to move in opposite directions. When the two limit strips 31 contact the thin-walled pure aluminum plate, the thin-walled pure aluminum plate can be limited. Then, the electric push cylinder 3 is started. The electric push cylinder 3 drives the bending plate 4 to move. The bending plate 4 then cooperates with the forming block 2 to bend and form the thin-walled pure aluminum plate. If the size and shape of the thin-walled pure aluminum plate are inconsistent with the existing forming block 2 and bending plate 4, the rotating column 26 can be used to drive the threaded rod 25 to move within the threaded hole 24. When the threaded rod 25 moves, it will drive the movable plate 20 to move within the movable cavity 19 of the connecting block 18. When the movable plate 20 moves, it will drive the locking rod 22 to move within the through hole 21. When one end of the locking rod 22 is disengaged from the locking hole 23, the fixing of the forming block 2 can be released. Then, the forming block 2, which matches the size and shape of the thin-walled pure aluminum plate, can be placed on the top of the workbench 1. The rotating column 26 can then be used to drive the threaded rod 25 to move within the threaded hole 24. The rod 25 moves within the threaded hole 24. As the rod 25 moves, it drives the movable plate 20 to move within the movable cavity 19 of the connecting block 18. The movable plate 20, in turn, drives the locking rod 22 to move within the through hole 21. When one end of the locking rod 22 is inside the locking hole 23, the forming block 2 can be fixed. The first connecting plate 13 and the second connecting plate 14 can be used to drive the telescopic rod 12 and the spring 17 to retract. At this time, the first connecting plate 13 and the second connecting plate 14 will move closer to each other. When the first locking pin 15 moves from the first limiting hole 8, the third limiting hole 10, and the second... After the locking pin 16 disengages from the second limiting hole 9 and the fourth limiting hole 11, remove the telescopic rod 12, the first connecting plate 13, the second connecting plate 14, the first locking pin 15, and the second locking pin 16 from the connecting groove 7. This releases the fixation on the bent plate 4. Remove the receiving frame 6 from the outside of the receiving block 5 to disassemble the bent plate 4. Then, attach the receiving frame 6 of the bent plate 4, which is compatible with the size and shape of the thin-walled pure aluminum plate, to the bottom of the receiving block 5. Finally, place the telescopic rod 12, the first connecting plate 13, the second connecting plate 14, the first locking pin 15, and the second locking pin 16 into the connecting groove. Inside 7, the spring 17 will drive the telescopic rod 12 to stretch. When the telescopic rod 12 stretches, it will drive the first connecting plate 13 and the second connecting plate 14 to move away from each other. When the first locking post 15 is located inside the first limiting hole 8 and the third limiting hole 10, and the second locking post 16 is located inside the second limiting hole 9 and the fourth limiting hole 11, the bending plate 4 can be fixed. Therefore, this utility model facilitates the flexible replacement of the forming block 2 and the bending plate 4, so that the forming block 2 and the bending plate 4 can be used for bending and forming thin-walled pure aluminum plates of different sizes and shapes, and has good applicability.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
