Description

Technical Field

[0001] The present invention relates to the technical field of bending devices, and particularly relates to a bending device for aluminum product processing. Background Art

[0002] In the design of many industrial products and building components, it is often necessary to form various specific shapes of aluminum plates, such as L-shaped, U-shaped, Z-shaped, etc. Through the bending process, the originally flat aluminum plate can be bent into the required shape to meet different assembly and use requirements.

[0003] In the related art, a bending machine is usually used to bend aluminum plates. During the bending process of the aluminum plate, the inner layer is under pressure and the outer layer is under tensile stress. These two stresses will cause plastic bending deformation of the aluminum material. During the process of transitioning from tensile stress to compressive stress, there will be an elastic stage in the middle. When in the elastic stage, the aluminum material has a tendency to straighten back to its original position. This situation is called springback in the bending work.

[0004] Chinese Patent with the authorization announcement number CN112044993B discloses a bending and forming processing machine for curtain wall aluminum plates. This patent includes: a workbench and an adjusting device arranged above the workbench. A first U-shaped frame with an opening downward is arranged on the top of the workbench. A driving device is arranged on the top of the first U-shaped frame. A punching device is arranged at the center of the top of the first U-shaped frame. The adjusting device includes a bidirectional screw rod that horizontally penetrates the two side walls of the workbench. Knobs are fixedly connected to both ends of the bidirectional screw rod. First sliding grooves are symmetrically opened on the top of the workbench, and there is a distance between the two groups of first sliding grooves. The bidirectional screw rod penetrates the first sliding grooves and is threadedly connected to the two ends of the first sliding grooves. Moving plates are symmetrically screwed on the outer wall of the bidirectional screw rod. The moving plates are composed of a vertical section and a horizontal section vertically arranged on the opposite sides of the two moving plates.

[0005] The above patent makes the punching device move up and down reciprocally to repeatedly squeeze and bend the middle part of the aluminum plate, thereby being able to reduce the additional stress generated by the aluminum plate during a single bending and prevent the aluminum plate from springing back.

[0006] However, the above patent drives the punching device to move downward through an incomplete gear, so the downward movement distance of the punching device is a fixed value. When processing aluminum plates with different thicknesses, if the aluminum plate is thinner, the extrusion distance of the punching device is insufficient, resulting in a larger bending angle of the aluminum plate; if the aluminum plate is thicker, the extrusion distance of the punching device is too large, resulting in a smaller bending angle. As a result, the above patent cannot accurately control the bending angle of the aluminum plate. Therefore, a new type of bending device is needed that can solve the problem of aluminum plate springback and is also applicable to bending aluminum plates with different thicknesses. Summary of the Invention

[0007] The present invention provides a bending device for aluminum product processing, aiming to solve the problem in the related art that the bending angle of an aluminum plate cannot be controlled when processing aluminum plates with different thicknesses.

[0008] The bending device for aluminum product processing of the present invention includes: a frame body, an upper pressing plate, a lower pressing plate, and a driving assembly; Both the upper pressing plate and the lower pressing plate are arranged on the frame body. The upper pressing plate is located above the lower pressing plate, and the driving assembly is used to drive the upper pressing plate to move up and down; The driving assembly includes a first driving member and a driving plate. The first driving member is arranged at the top of the frame body. The driving plate is connected to the output end of the first driving member. The first driving member is a hydraulic cylinder. The first driving member is used to drive the driving plate to move up and down. A connecting rod is arranged between the driving plate and the upper pressing plate. Two ends of the connecting rod are respectively connected to the driving plate and the upper pressing plate. The first driving member can drive the upper pressing plate to reciprocate up and down through the driving plate; The upper pressing plate includes a first plate and a second plate. The first plate is rotatably connected to the second plate. An upper bending mechanism is arranged between the upper pressing plate and the driving plate. The upper bending mechanism is used to drive the first plate to rotate relative to the second plate to realize the bending of the upper pressing plate. The lower pressing plate includes a third plate and a fourth plate. A lower bending mechanism is arranged between the lower pressing plate and the frame body. The lower bending mechanism is used to drive the third plate to rotate relative to the fourth plate to realize the bending of the lower pressing plate.

[0009] The beneficial effects are as follows: The first driving member is a hydraulic cylinder, which drives the driving plate to move up and down, thereby driving the upper pressing plate to move up and down. The first driving member can adjust the moving distance of the upper pressing plate up and down according to the thickness of different aluminum plates, so as to accurately bend the aluminum plate. The upper pressing plate and the lower pressing plate can be bent. During the bending process, the upper pressing plate and the lower pressing plate squeeze the aluminum plate multiple times. And after each squeeze, both the upper pressing plate and the lower pressing plate deform through the upper bending mechanism and the lower bending mechanism, thereby reducing the included angle between the two, so that each squeeze can make the aluminum plate bend slightly. Eventually, until the aluminum plate reaches the bending angle required by the design. Since the bending angle each time is small, the additional stress generated by the aluminum plate during the bending process is small, reducing the risk of aluminum plate springback.

[0010] Preferably, a first rotating shaft is arranged between the first plate and the second plate. The first rotating shaft is respectively in rotational cooperation with the first plate and the second plate. The first rotating shaft is in rotational cooperation with the connecting rod.

A limiting rod is arranged on the frame body. The second rotating shaft is in rotational cooperation with the limiting rod. The first rotating shaft and the second rotating shaft are distributed at intervals up and down.

[0011] The effect is that by rotating the first plate and the second plate around the first rotating shaft, and the third plate and the fourth plate around the second rotating shaft, and fixing the first rotating shaft and the second rotating shaft through the connecting rod and the limiting rod, the first rotating shaft and the second rotating shaft are always vertically and parallelly spaced apart, preventing the upper pressing plate and the lower pressing plate from shifting during the deformation process, and further preventing the bending failure.

A second stabilizing sleeve is arranged on the second movable shaft, and the second stabilizing sleeve is in sliding cooperation with the first screw rod.

[0014] The effect is that setting the first stabilizing sleeve and the second stabilizing sleeve can enable both the first movable shaft and the second movable shaft to be stressed at two points, so that the stress on both of them is uniform, and the service life of the first movable shaft and the second movable shaft is improved.

[0015] Preferably, the first pull rod includes a first section and a second section. The first section can extend into the second section, and the first section and the second section are connected by a first elastic member.

The lower bending mechanism has the same structure as the upper bending mechanism, and the lower bending mechanism is arranged on the frame body.

[0017] Preferably, a clamping mechanism is arranged on the lower pressing plate. The clamping mechanism is used to clamp the aluminum plate, and further can prevent the aluminum plate from shaking during the bending process.

[0018] The effect is that the clamping mechanism can clamp the aluminum plate and prevent the aluminum plate from shaking during the bending process.

[0019] Preferably, the clamping mechanism includes a first clamping block and a second clamping block. The first clamping block includes a sliding plate and a clamping plate. A sliding groove is provided on the third plate. The sliding plate is slidably engaged in the sliding groove. The sliding plate and the third plate are horizontally distributed and can slide along the sliding groove. The sliding plate is connected to the third plate through a second elastic member. The clamping plate is provided on the sliding plate and is vertically distributed with respect to the sliding plate. An arc-shaped groove is provided on the side wall of the clamping plate, and the arc-shaped groove can abut against the aluminum plate. The second clamping block has the same structure as the first clamping block. The second clamping block is slidably engaged on the fourth plate. The first clamping block and the second clamping block are symmetrically distributed.

[0020] Preferably, a dust cover is provided on the frame.

[0021] By adopting the above technical solutions, the beneficial effects of the present invention are as follows: According to the bending device for aluminum products processing of the present invention, the first driving member is a hydraulic cylinder, which drives the driving plate to move up and down, thereby driving the upper pressing plate to move up and down.

The third movable shaft 77 is in threaded fit with the third screw rod 74. A third stabilizing sleeve is arranged on the third movable shaft 77. The third stabilizing sleeve is in sliding fit with the fourth screw rod 75. The fourth movable shaft 78 is in threaded fit with the fourth screw rod 75.

Two second pull rods 710 are rotatably fitted on the fourth movable shaft 78. These two second pull rods 710 are hinged to the fourth plate 32.

[0039] The third driving member 71 drives the fourth gear 73 to rotate through the third gear 72. The third screw rod 74 rotates synchronously with the fourth gear 73 and drives the fourth screw rod 75 to rotate synchronously through the second transmission belt 76, so that the third movable shaft 77 and the fourth movable shaft 78 move towards each other or away from each other. When the third movable shaft 77 and the fourth movable shaft 78 move towards each other, the third plate 31 and the fourth plate 32 are pushed through the corresponding second pull rods 710, so that the third plate 31 and the fourth plate 32 rotate towards each other around the second rotating shaft 33. The included angle between the third plate 31 and the fourth plate 32 decreases, and the third plate 31 and the fourth plate 32 are distributed in a V shape.

[0040] As Figure 2 and Figure 6As shown in the figure, a clamping mechanism is further provided on the lower pressing plate 3. The clamping mechanism includes a first clamping block 81 and a second clamping block 82. Sliding grooves are provided at the left end of the third plate 31 and the right end of the fourth plate 32. The first clamping block 81 is slidably fitted in the sliding groove of the third plate 31, and the second sliding block 5115 is slidably fitted in the sliding groove of the fourth plate 32.

The sliding plate 811 can move left and right along the sliding groove. The clamping plate 812 is fixedly arranged on the sliding plate 811 and is perpendicular to the sliding plate 811. An arc-shaped groove is provided on the side wall of the clamping plate 812. The second clamping block 82 has the same structure as the first clamping block 81, and the first clamping block 81 and the second clamping block 82 are symmetrically arranged. The first clamping block 81 and the second clamping block 82 can clamp the aluminum plate 100, thereby preventing the aluminum plate 100 from shaking during bending. In some other embodiments, the clamping plate 812 can be a straight plate. An active block is provided on the clamping plate 812. The active block is elastically connected to the clamping plate 812 by a spring. A clamping groove is formed between the spring and the sliding plate 811. The aluminum plate 100 extends into the clamping groove. The upper surface of the aluminum plate 100 abuts against the active block. The spring provides a thrust force for the active block, so that the active block presses the aluminum plate 100, thereby fixing the aluminum plate 100.

[0041] The implementation principle of the bending device for aluminum products in the embodiment of the present invention is as follows: In the initial state, both the upper pressing plate 2 and the lower pressing plate 3 are in a horizontal state, and the upper pressing plate 2 and the lower pressing plate 3 are spaced apart.

[0042] Place the aluminum plate 100 on the lower pressing plate 3, and clamp the aluminum plate 100 by the first clamping block 81 and the second clamping block 82. Subsequently, the driving assembly drives the upper pressing plate 2 to move downward and presses the aluminum plate 100 to ensure that the aluminum plate 100 is in a flat state. Then, the driving assembly drives the upper pressing plate 2 to move upward. When the upper pressing plate 2 moves upward, the upper bending mechanism and the lower bending mechanism operate simultaneously, and the upper pressing plate 2 and the lower pressing plate 3 are deformed simultaneously, so that the angle between the first plate 21 and the second plate 22 decreases, the angle between the third plate 31 and the fourth plate 32 decreases, and the bending angles of the upper pressing plate 2 and the lower pressing plate 3 are the same. Subsequently, the driving assembly drives the upper pressing plate 2 to move downward and presses the aluminum plate 100. The aluminum plate 100 is pressed to achieve a small degree of bending. After the bending is completed, the driving assembly drives the upper pressing plate 2 to move upward and repeats the above process. As the number of pressing times increases, the angle of the aluminum plate 100 becomes smaller and smaller, and finally reaches the angle required by the design. Since the single bending is divided into multiple bendings, the additional stress generated by the aluminum plate 100 during each bending process is reduced, thereby preventing the aluminum plate 100 from rebounding.
