Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of aluminum plate processing equipment, and specifically to an aluminum plate bending processing equipment. Background Technology
[0002] A bending machine is a device used to bend aluminum sheets or aluminum alloy sheets by using external mechanical force to bend the aluminum sheet into the required angle or shape.
[0003] When using a bending machine to bend aluminum sheets, the aluminum sheet is usually placed on the lower die, and then the cylinder on the bending machine is started to drive the upper die downward, pressing the aluminum sheet into the interior of the lower die. Through the corresponding fit between the lower protrusion of the upper die and the internal cavity of the lower die, the aluminum sheet is bent into the required shape, such as a V-shape or a U-shape.
[0004] Due to the precision deviation of the conveying device and the vibration generated during the movement of the cylinder, the position of the aluminum plate on the lower mold may shift, which in turn affects the precision of the aluminum plate bending and forming, reduces the production efficiency of aluminum plates, and increases the production cost. On the other hand, since the bending process of aluminum plates requires the activation of the cylinder on the bending machine to drive the upper mold downward and squeeze the aluminum plate into the interior of the lower mold, the upper mold is relatively heavy. If there is air leakage in the cylinder or unexpected external force, the upper mold may fall rapidly in an unexpected manner, posing a safety hazard to the surrounding environment and personnel.
[0005] Therefore, there is an urgent need to provide a new solution to address the defects and shortcomings of the existing technologies. Utility Model Content
[0006] In order to overcome the defects and shortcomings of the existing technology, this utility model provides an aluminum plate bending processing device.
[0007] The technical solution adopted by this utility model to solve its technical problem is:
[0008] An aluminum sheet bending processing device includes a bending machine. The bending machine has a lower mold and an upper mold inside. The lower mold is fixed to the top of the bending machine, and the upper mold is located above the lower mold and can move up and down relative to the lower mold.

[0013] As a further preferred embodiment of the present invention, a pull block is fixedly installed at the bottom of the card block.
[0014] As a further preferred embodiment of the present invention, an auxiliary mechanism is provided between the slide frame and the limiting rod. The auxiliary mechanism includes a scale fixed to both sides of the slide frame and a pointer fixed to the bottom of the limiting rod, with the pointer located outside the scale.
[0015] As a further preferred embodiment of the present invention, the protective device includes a protective frame, the inner wall of the bending machine is provided with a plurality of sliding holes, and sliding rods are symmetrically fixed on both sides of the protective frame, the sliding rods being slidably installed inside the sliding holes.

[0019] 1) This utility model provides an aluminum plate bending processing device. By setting a limiting device, the aluminum plate placed on the lower mold can be limited, ensuring the accuracy of bending processing, reducing production costs, and improving the processing quality and production efficiency of aluminum plates.
[0020] 2) This utility model provides an aluminum plate bending processing device.

[0031] [First Embodiment]
[0032] like Figure 1-5 The image shows an aluminum plate bending processing device provided in the first embodiment of this utility model, as shown below. Figure 1 As shown, the device includes a bending machine 1. The bending machine 1 has a lower mold 4 and an upper mold 6 inside. The lower mold 4 is fixed to the top of the bending machine 1. The upper mold 6 is located above the lower mold 4 and can move up and down relative to the lower mold 4. A cylinder 5 is installed on the top of the bending machine 1. The output end of the cylinder 5 passes through the top of the bending machine 1 and is fixedly connected to the upper mold 6. The cylinder 5 drives the upper mold 4 to move downward, pressing the aluminum plate into the interior of the lower mold 4. Through the corresponding matching shape of the lower protrusion of the upper mold 6 and the internal cavity of the lower mold 4, the aluminum plate is bent into the corresponding required shape, such as a V-shape or a U-shape.
[0033] The improvement of this embodiment compared with the prior art is that: limiting devices 2 are provided on both sides of the lower mold 4, and a protective device 3 is provided inside the bending machine 1; by setting the limiting devices 2, the aluminum plate placed on the lower mold 4 can be limited, ensuring the accuracy of bending processing, reducing production costs, and improving the processing quality and production efficiency of aluminum plate; at the same time, by setting the limiting devices 2 on both sides of the lower mold 4, the limiting devices 2 on both sides can be adjusted separately, thereby adapting to bending processing at different positions on both sides of the aluminum plate, improving the compatibility of the limiting devices and the bending machine; and by setting the protective device 3, when the bending machine 1 is not working, the protective device 3 can block the upper mold 6, avoiding the safety risks that may be caused by the rapid descent of the upper mold 6 due to unexpected situations, improving the safety of the bending machine; when the bending machine is working, the protective device 3 can be stored on one side of the bending machine to avoid obstructing the bending processing, and is easy to put away and put away.
[0034] like Figure 3-4 As shown, the limiting device 2 in this embodiment includes a slide frame 21 fixed on both sides of the lower mold 4, and a limiting rod 23 is slidably installed inside the slide frame 21. Through the sliding process of the limiting rod 23 inside the slide frame 21 relative to the slide frame 21, the position of the limiting rod 23 can be adjusted to meet the limiting requirements of aluminum plates of different widths.
[0035] To ensure the sliding stability of the limiting rod 23 relative to the slide rail 21, the internal parts of the limiting rod 23 and the slide rail 21 need to be configured with corresponding sliding fits that can limit each other, for example... Figure 3-4 As shown, in this embodiment, the inner wall cross-section of the slide frame 21 is set to a cross shape, and the cross-section of the limiting rod 23 is set to a corresponding cross shape. In order to achieve the same technical effect, those skilled in the art should know that the interior of the slide frame 21 and the limiting rod 23 can also be set to other corresponding shapes.
[0036] To limit the sliding position of the limiting rod 23 relative to the slide frame 21, several slots 22 are provided on both sides of the inner wall of the slide frame 21. A locking block 25 is slidably installed at the bottom of the limiting rod 23. The locking block 25 slides upward and is inserted into the slot 22. The locking block 25 slides downward and disengages from the slot 22. When the locking block 25 is slid downward and disengaged from the slot 22, the limiting rod 23 is unlocked and can slide relative to the slide frame 21. When the limiting rod 23 slides relative to the slide frame 21 to a preset position, the locking block 25 slides upward and is inserted into the corresponding slot 22, thereby locking the limiting rod 23 relative to the slide frame 21 at the current sliding position. To facilitate the control of the lifting and sliding process of the locking block 25, a pull block 26 is fixedly installed at the bottom of the locking block 25.
[0037] As a further preferred embodiment, to facilitate the automatic upward sliding reset process after the locking block 25 is pulled down and slid down, a first elastic element 24 and a telescopic rod 27 are provided between the limiting rod 23 and the locking block 25. The first elastic element 24 is sleeved on the outer periphery of the telescopic rod 27. The first elastic element 24 can be a spring or other elastic reset element commonly used in the mechanical field. This arrangement ensures that when the locking block 25 is pulled down to slide down and disengage from the slot 22, the telescopic rod 27 extends downward and the first elastic element 24 extends downward. When the locking block 25 is released after sliding to the preset position, the locking block 25 is pulled upward by the elastic restoring force of the first elastic element 24. At this time, the telescopic rod 27 retracts upward and the first elastic element 24 returns to its original state.
[0038] To further improve the sliding accuracy of the limit rod 23 relative to the slide frame 21, an auxiliary mechanism 28 is provided between the slide frame 21 and the limit rod 23. The auxiliary mechanism 28 includes a scale 281 fixed on both sides of the slide frame 21 and a pointer 282 fixed on the bottom of the limit rod 23. The pointer 282 is located outside the scale 281. By measuring the scale on the scale 281 when the limit rod 23 slides relative to the slide frame 21, the current adjustment position and adjustment stroke are determined, so as to further improve the sliding accuracy of the limit rod 23 relative to the slide frame 21.
[0039] like Figure 2 and Figure 5 As shown, the protective device 3 in this embodiment includes a protective frame 32. The inner wall of the bending machine 1 is provided with several sliding holes 31. Sliding rods 33 are symmetrically fixed on both sides of the protective frame 32. The sliding rods 33 are slidably installed inside the sliding holes 31. When the bending machine 1 is not working, the sliding rods 33 extend inward inside the sliding holes 31 to block the upper mold 6, avoiding the safety risks that may be caused by the rapid descent of the upper mold due to unexpected conditions, and improving the safety of the bending machine 1. When the bending machine 1 is working, the sliding rods 33 can be pushed outward inside the sliding holes 31 to be stored on one side of the bending machine 1 to avoid hindering the bending process, and the storage and storage are convenient.
[0040] To further achieve the automatic reset effect of the slide rod 33 after it is pushed outward inside the sliding hole 31, a second elastic element 34 is sleeved on the outer periphery of the slide rod 33. The two ends of the second elastic element 34 are fixedly connected to the inner wall of the bending machine 1 and the protective frame 32, respectively. The second elastic element 34 can be a spring or other elastic reset element commonly used in the mechanical field. This arrangement ensures that when the bending machine 1 is working, the slide rod 33 is pushed outward inside the sliding hole 31 to be stored on one side of the bending machine 1. At this time, the second elastic element 34 is compressed. When the bending machine 1 is not working, due to the elastic restoring force of the second elastic element 34, the slide rod 33 can automatically extend inward inside the sliding hole 31 to return to its original position, thereby blocking the upper mold 6.
[0041] To lock the sliding position of the slide rod 33 relative to the sliding hole 31, several rotating blocks 35 are rotatably sleeved on the outer periphery of the slide rod 33. The rotating blocks 35 can be adjusted by their rotation angle to pass through the sliding hole 31 or be blocked outside the sliding hole 31. When the rotating block 35 rotates to the same angular position as the sliding hole 31, the slide rod 33 can drive its rotating block 35 to pass through the sliding hole 31. However, when the rotating block 35 rotates to a position inconsistent with the angular position of the sliding hole 31, the rotating block 35 cannot pass through the sliding hole 31, thus achieving the locking effect of the slide rod 33 in its current position inside the sliding hole 31. Figure 2 and Figure 5 As shown, the cross-sections of the rotating block 35 and the sliding hole 31 need to be set to fit each other. In order to achieve good contact with the bending machine 1, an anti-slip block 36 is fixed on the side of the rotating block 35 near the bending machine 1. The anti-slip block 36 is preferably made of rubber.
[0042] The specific working process of this embodiment is as follows:
[0043] When using the bending machine 1 to bend the aluminum plate, the aluminum plate is placed on the lower mold 4. The control block 25 slides downward to disengage from the current slot 22, thereby unlocking the limit rod 23. At this time, the first elastic element 24 and the telescopic rod 27 are stretched downward. Then, the control block 23 slides inside the slide frame 21 to the preset position until the inner side of the limit rod 23 abuts against the edge of the aluminum plate. At this time, the block 25 is released, allowing it to slide upward into the slot corresponding to the current position under the elastic reset action of the first elastic element 24. The groove 22 is used to lock the limiting rod 23 in the current sliding position. Similarly, the same operation is performed on the limiting rod 23 on the other side of the lower mold 4. This can limit the aluminum plate on both sides, ensuring the accuracy of the bending process, reducing production costs, and improving the processing quality and production efficiency of the aluminum plate. At the same time, by setting the limiting devices 2 on both sides of the lower mold 4, the limiting devices 2 on both sides can be adjusted separately, thereby adapting to bending processes at different positions on both sides of the aluminum plate and improving the compatibility of the limiting devices and the bending machine.
[0044] Then, the cylinder 5 on the bending machine 1 is started to drive the upper mold 6 to move downward, pressing the aluminum plate into the interior of the lower mold 4, thus achieving the effect of bending the aluminum plate.
[0045] When the bending machine 1 is working, the second elastic element 34 is in a retracted state, storing the protective frame 32 on one side of the bending machine 1. Then, the cylinder 5 is started to move the upper mold 6 upward to the preset position. The corresponding rotating block 35 is rotated to align with the sliding hole angle 31. At this time, the protective frame 32 will move inward under the elastic reset action of the second elastic element 34, causing the sliding rod 33 to slide inward in the sliding hole 31, so that the inner side of the protective frame 32 abuts against the lower part of the upper mold 6, blocking it and avoiding the safety risks that may be caused by the rapid descent of the upper mold 6 due to unexpected situations, thus improving the safety of the bending machine 1. Similarly, when the bending machine 1 is working again, the sliding rod 33 slides outward in the sliding hole 31 to store the protective frame 32 on one side of the bending machine 1, and the rotating block 35 limits its current position to avoid hindering the bending process, making it easy to put in and take out.
[0046] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
