Description

Technical Field

[0001] The invention relates to the technical field of production and processing of aluminum-plastic plates, and in particular to a bending device for processing aluminum-plastic plates. Background Art

[0002] As a new type of decorative material, aluminum-plastic panels have quickly gained popularity due to their economy, variety of optional colors, convenient construction methods, excellent processing performance, excellent fire resistance and noble quality. The unique properties of aluminum-plastic panels themselves determine their wide range of uses: they can be used for building exterior walls, curtain wall panels, renovation of old buildings, interior wall and ceiling decoration, advertising signs, display stands, purification and dust prevention projects. They are a new type of building decoration material. During the decoration process, aluminum-plastic panels need to be bent when encountering obstacles such as wall beams.

[0003] Traditional aluminum-plastic plate bending machines can only bend one crease. When both sides of the aluminum-plastic plate are bent at the same time, if the side needs to be bent, a circular operation or manual handling is required to complete the bending of the aluminum-plastic plate.

[0004] The Chinese patent with patent publication number CN117549541B discloses an aluminum-plastic plate bending device and a bending method thereof. By setting a main bending component, a mold component and a side bending component, the aluminum-plastic plate can be bent at one time. On the one hand, it can simplify the work process, reduce repeated operations, save time, and improve production efficiency. On the other hand, it lowers the technical threshold and is easier for workers to master.

[0005] Although the above technical solution solves the technical defect that the existing aluminum-plastic panel cannot complete the bending operation in one go, the solution and the existing technology still have the following technical defects:

[0006] The bending mechanism is fixed and the bending angle of the aluminum-plastic plate cannot be adjusted; when the existing aluminum-plastic plate bending machine needs to bend the aluminum-plastic plate into an arc after bending the aluminum-plastic plate at a right angle (bevel), the aluminum-plastic plate bending machine can only be replaced, which is troublesome to carry, increases production costs, and affects production efficiency. Summary of the invention

[0007] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a bending device for processing aluminum-plastic panels.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Embodiment 1:

[0038] like Figure 1 As shown, the present invention provides a bending device for aluminum-plastic plate processing, including two brackets 1, the inner sides of the two brackets 1 are fixedly connected with a transversely arranged guide rail 1 11 and a guide rail 2 12, specifically, the guide rail 1 11 is located above the guide rail 2 12.

[0039] like Figure 1-Figure 4 As shown, a rotating first pressing block 2 is arranged between the two brackets 1, and connecting mechanisms 1 are connected to both sides of the first pressing block 2. The first pressing block 2 slides on the guide rail 11 through the connecting mechanism 1.

[0040] Furthermore, the first pressing block 2 slides up and down on the connecting mechanism 1.

[0041] A rotating second pressing block 3 is also arranged between the two brackets 1. The two sides of the two second pressing blocks 3 are respectively connected with connecting mechanisms 2. The two second pressing blocks 3 slide on the guide rail 2 12 through the connecting mechanisms 2. Specifically, the two second pressing blocks 3 are arranged in a mirror-symmetrical manner.

[0042] In this embodiment, connecting mechanism 1 and connecting mechanism 2 are not limited to sliding along bracket 1 only through guide rails, but can also slide along bracket 1 through other means, for example, by opening a horizontal sliding groove from top to bottom in bracket 1, and connecting mechanism 1 and connecting mechanism 2 slide along bracket 1 through the sliding groove respectively.

[0043] In this embodiment, the first pressing block 2 and the second pressing block 3 have the same shape, both having two inclined surfaces, and the two inclined surfaces are connected by a cylindrical surface transition.

[0044] like Figure 1 As shown, an aluminum-plastic plate 4 is arranged on the second pressing block 3 , and a bending component 5 is arranged on one side of the second pressing block 3 .

[0045] like Figure 1 , Figure 2 As shown, the connecting mechanism 1 includes a first slider 21, a lead screw 22, a connecting plate 23 and a first rotating rod 24.

[0046] The first slider 21 is fixedly connected with a lead screw 22, the lead screw 22 is connected with a connecting plate 23 that can slide up and down, the connecting plate 23 is connected with a rotatable first rotating rod 24, and the connecting plate 23 can be fixedly connected with a sleeve for sleeve-mounting the first rotating rod 24;

[0047] The first rotating rod 24 passes through the first pressing block 2, and the first rotating rod 24 is coaxial with the cylindrical surface of the first pressing block 2. The first sliding block 21 is slidably connected to the guide rail 11. A driving device for driving the first rotating rod 24 to rotate is provided on the connecting plate 23. In this embodiment, the driving device is a motor, which drives the first rotating rod 24 to rotate the first pressing block 2.

[0048] like Figure 1 , Figure 3 As shown, the second connecting mechanism includes a second slider 31 and a second rotating rod 32.

[0049] The second slider 31 is slidably connected to the guide rail 12, and a rotatable second rotating rod 32 is connected to the second slider 31. Specifically, the second rotating rod 32 passes through the second pressing block 3 and is coaxial with the cylindrical surface of the second pressing block 3. A driving device is provided on the second slider 31, and the driving device drives the second rotating rod 32 to rotate. A shaft sleeve is fixedly connected to the second slider 31 to facilitate the second rotating rod 32 to rotate therein.

[0050] Further, such as Figure 4 As shown, in order to enable the first rotating rod 24 to drive the first pressing block 2 to rotate, a protrusion 25 is fixedly connected to the first rotating rod 24. The shape of the protrusion 25 is not limited, and it can limit the first pressing block 2 to rotate together with the first rotating rod 24. For example, the first rotating rod 24 can be a rectangular long block, and a groove for installing the protrusion 25 is provided in the corresponding first pressing block 2.

[0051] The second rotating rod 32 is also provided with a protrusion 25 , and the structure of the second pressing block 3 is changed accordingly.

[0052] like Figure 1 , Figure 6 , Figure 7 As shown, the bending assembly 5 is located on one side of the second pressing block 3 and is used for bending the aluminum-plastic plate 4 .

[0053] Specifically, the bending assembly 5 includes a push plate 51, a clamping plate 52, and a lifting rod 53.

[0054] The push plate 51 is provided with a clamping plate 52 which can move up and down. The movable distance of the clamping plate 52 on the push plate 51 is adjusted to clamp and release the aluminum-plastic panel 4. The clamping plate 52 can be set on the push plate 51 through a screw. The push plate 51 and the clamping plate 52 clamp the aluminum-plastic panel 4, which can improve the stability during bending and the accuracy of the bending angle.

[0055] Furthermore, the upper end of the lifting rod 53 is movably connected to the bottom of the push plate 51, and the lower end is fixedly connected to the ground or a base for supporting the entire bending device. The bending assembly 5 is pushed upward by the lifting rod 53 to bend the aluminum-plastic plate 4.

[0056] The bending assembly 5 is pushed upward by the lifting rod 53 , so as to adjust the bending angle of the aluminum-plastic plate 4 .

[0057] Specifically, the lifting rod 53 of this embodiment adopts an electric hydraulic lifting rod, so that the bending assembly 5 can rise steadily and can stop rising at any time to adjust the bending angle of the aluminum-plastic plate 4. The electric hydraulic lifting rod is a prior art, so it will not be described in detail.

[0058] When the side of the aluminum-plastic panel 4 needs to be bent at a right angle or an oblique angle by the bending assembly 5, the second pressing block 3 is used to carry the aluminum-plastic panel 4, the upper inclined surface of the second pressing block 3 is flush with the horizontal, the aluminum-plastic panel 4 is placed on two or one of the second pressing blocks 3, and the lower inclined surface of the first pressing block 2 is flush with the horizontal, which is convenient for pressing down and compacting the aluminum-plastic panel 4, and then cooperates with the bending assembly 5 to complete the bending work.

[0059] Specifically, the first pressing block 2 slides to the top of the aluminum-plastic plate 4 through a connecting mechanism, and is driven downward by the lead screw 22, and the bending assembly 5 then bends the side of the aluminum-plastic plate 4. In this embodiment, the bending part of the aluminum-plastic plate 4 has been pre-grooved to facilitate bending.

[0060] like Figure 4 As shown, in order to facilitate the user to control the rotation angle of the first pressure block 2 and the second pressure block 3, especially the inclined surfaces of the first pressure block 2 and the second pressure block 3 are difficult to calibrate to be flush with the horizontal plane, a stopper 26 is provided on one end close to the first rotating rod 24 and the second rotating rod 32. When the inclined surfaces of the first pressure block 2 and the second pressure block 3 are rotated to be flush with the horizontal plane, the stopper 26 respectively abuts against the connecting plate 23 and the second sliding block 31, and the first pressure block 2 and the second pressure block 3 cannot continue to rotate.

[0061] Embodiment 2:

[0062] Considering that the above embodiment can bend the aluminum-plastic plate 4 at a right angle or an oblique angle, but cannot bend the aluminum-plastic plate 4 into an arc, this embodiment further explains the above embodiment to achieve bending the aluminum-plastic plate 4 into an arc, specifically:

[0063] like Figure 5 As shown, when the aluminum-plastic plate 4 needs to be bent into an arc, the driving device drives the first pressing block 2 to rotate to the circular surface downward, and the second pressing block 3 to rotate to the circular surface upward, and the position of the first pressing block 2 is adjusted through the connecting mechanism 1 so that the first pressing block 2 is located above the middle of the two second pressing blocks 3.

[0064] The connecting plate 23 of the first pressing block 2 moves downward on the lead screw 22, thereby bending the aluminum-plastic plate 4. The bending arc of the aluminum-plastic plate 4 is related to the downward pressing distance of the first pressing block 2. The further downward the first pressing block 2 is, the greater the bending arc of the aluminum-plastic plate 4 is. The cylindrical surfaces of the first pressing block 2 and the second pressing block 3 rotate to adjust the uniformity of the curvature of the aluminum-plastic plate 4.

[0065] Embodiment three:

[0066] Considering that after the aluminum-plastic plate 4 has two opposite sides bent, when the other two sides are bent, the first bent edge of the aluminum-plastic plate 4 interferes with the first pressing block 2, the second pressing block 3, and the bending assembly 5, this embodiment is further improved on the basis of the above embodiment, specifically:

[0067] like Figure 8 As shown,

[0068] A plurality of slots 6 are provided on the first pressing block 2 and the second pressing block 3. An elastic block 61 is provided on one side of the slot 6 of the first pressing block 2 and the second pressing block 3. The elastic block 61 is made of an elastic material such as rubber, silicone, etc. A plurality of elastic members 62 are provided in the elastic block 61. The elastic member 62 can be an elastic member such as a spring, a shrapnel, etc. In the present embodiment, the elastic member 62 is a spring.

[0069] The slot 6 can be pressed inwards so that the bent edge can extend into the slot 6, and the elastic member 62 can then press the bent edge to securely clamp it.

[0070] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
