Description

Technical Field

[0001] The present invention relates to the field of photovoltaic panel support processing, and more specifically, it relates to a bending mold for photovoltaic panel support processing. Background Art

[0002] In the installation process of photovoltaic panels, the bracket is a crucial component. It not only determines whether the photovoltaic panel can be firmly fixed in the predetermined position, but also directly affects the overall performance and aesthetics of the photovoltaic system. The connector in the bracket is the key to ensuring the stability of the entire structure. In the traditional connector manufacturing process, sheet metal materials usually need to go through multiple processes such as cutting, stamping, and bending to form the required shape. Especially in the bending process, each edge often needs to be operated one by one. This single-sided bending method is not only time-consuming, but also has low production efficiency, and it is difficult to meet the needs of large-scale production and rapid delivery. In order to improve production efficiency, mold stamping is generally used to place the sheet metal to be bent on the bending lower mold, and then the bending upper mold is pressed down to achieve bending. However, this bending method has the problem that there is no support at both ends of the sheet metal to be bent, which causes the sheet metal to be offset when the bending upper mold is pressed down, resulting in different sizes on both sides of the bent connector. In order to solve the above problems, a bending mold for photovoltaic panel bracket processing is proposed. Summary of the invention

DETAILED DESCRIPTION

[0027] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0029] In the present invention, unless otherwise specified, the directions used, such as "up" and "down", usually refer to the directions shown in the drawings, or to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0030] For examples, see Figure 1 - Figure 6 A bending mold for processing a photovoltaic panel bracket comprises a workbench 1, a processing area 2 is arranged on the workbench 1, and a hydraulic column 3 is arranged at the top of the processing area 2, a bending mechanism 4 is arranged at the bottom of the hydraulic column 3, and a clamping mechanism 5 is arranged on the bending mechanism 4, a bending lower die 6 is fixedly installed at the bottom of the processing area 2, and the bending lower die 6 and the bending mechanism 4 correspond to match and bend, the bending mechanism 4, the clamping mechanism 5 and the bending lower die 6 are located on the same axis, and the bottom end of the clamping mechanism 5 protrudes from the bottom end of the bending mechanism 4 in the initial state, the sheet metal to be bent is horizontally placed on the top of the bending lower die 6, and then the bending mechanism 4 is pushed downward by the hydraulic column 3, and the clamping mechanism 5 protrudes from the end of the bending mechanism 4 to first press the sheet metal to be bent on the top of the bending lower die 6, and the sheet metal to be bent is clamped and fixed to avoid side slipping of the sheet metal due to machine vibration when the sheet metal is bent, resulting in a situation where one side of the sheet metal after bending is longer and the other side is shorter.

[0031] Furthermore, after the clamping mechanism 5 clamps and fixes the sheet metal to be bent, the hydraulic column 3 continues to push the bending mechanism 4 downward, thereby bending the excess portions of the two ends of the sheet metal to be bent at the top of the lower bending die 6.

[0032] It should be noted that the sheet metal to be bent is only supported by the bending lower die 6 at this time, which is obviously unstable. In common situations, a frame for placing the sheet metal to be bent may be set above the bending lower die 6, and the four sides of the frame and the sheet metal to be bent are matched, so that after the sheet metal to be bent is placed on the frame, it is centered by the four sides of the frame, thereby improving the stability of the sheet metal to be bent on the top of the bending lower die 6. Although such a structure does solve the problem of centering and stability of the sheet metal to be bent, because the processing is batch, higher bending efficiency is required, and the matching of the four sides of the frame and the sheet metal to be bent causes the sheet metal to be bent to be placed. It cannot be placed at will and needs to be manually aligned, which reduces the bending efficiency.

[0033] Therefore, vertical plates 7 are fixedly installed on both sides of the bending lower die 6, and a movable cavity 8 is opened on the vertical plates 7. A rotating rod 9 is rotatably installed in the movable cavity 8, and a supporting plate 10 for supporting the sheet metal to be bent is arranged on the rotating rod 9.

[0034] In the initial state, the supporting surface of the pallet 10 is flush with the top of the bending lower die 6, and the spacing between the two vertical plates 7 is greater than the length of the sheet metal to be bent, and the spacing between the pallets 10 on the two vertical plates 7 is less than the length of the sheet metal to be bent, so that the sheet metal placement area composed of the supporting surface of the pallet 10 and the top of the bending lower die 6 is larger than the area of ​​the sheet metal to be bent, so that the sheet metal to be bent can be placed on the top of the bending lower die 6 at will, and there will be no problem of unstable placement and tipping over and falling.

[0035] The bending mechanism 4 includes a support seat 401 fixedly mounted on the bottom end of the hydraulic column 3, and also includes a bending upper die 402 fixedly mounted on the bottom end of the support seat 401. The bending upper die 402 and the bending lower die 6 are matched to perform bending.

[0036] The top of the bracket seat 401 and the bottom of the hydraulic column 3 are fixedly connected by bolts, and the bending upper die 402 and the bottom of the bracket seat 401 are fixedly connected by bolts. The bending upper die 402 is pressed down to match the bending lower die 6, so that the sheet metal to be bent can be bent on both sides, thereby improving the bending efficiency.

[0037] A movable groove 403 is formed at the bottom of the bracket seat 401 , and a through hole 404 is formed on the bending upper die 402 . The pressing mechanism 5 includes a pressing spring 501 and a pressing column 502 which are arranged in the movable groove 403 .

[0038] In the initial state, under the action of the extrusion spring 501, the bottom end of the clamping column 502 protrudes from the open bottom end of the bending upper mold 402, so that when the hydraulic column 3 pushes the bending upper mold 402 downward for bending, the clamping column 502 will first resist the sheet metal to be bent, thereby compressing the extrusion spring 501, and the sheet metal to be bent is clamped and fixed by the rebound force of the extrusion spring 501.

[0039] Among them, the clamping column 502 is a square column, and the clamping column 502 and the movable groove 403 are movably matched, so that after the clamping column 502 clamps and fixes the sheet metal to be bent, it will not rotate. If the clamping column 502 is round, then during the clamping process, the clamping column 502 will rotate, which may cause the sheet metal to be bent to rotate, thereby causing the position to be bent to change, making the bent connecting parts unusable.

[0040] A positioning plate 11 is provided on the side of the bending lower die 6 in the processing area 2 away from the loading direction, and the positioning plate 11 and the two vertical plates 7 are movably installed up and down. The setting of the positioning plate 11 can prevent the sheet metal to be bent from being placed too far backward and thus detaching from the bending lower die 6.

[0041] It should be explained here that in order to allow the sheet metal to be placed randomly and improve the efficiency of the bending process, a wider vertical plate 7 is set, and then two support plates 10 are used to support the sheet metal to be bent, so that it can be placed randomly and the work efficiency is improved. However, due to the random placement, the sheet metal to be bent is not centered, and there will be small distance errors. At the same time, the support plate 10 used to support the sheet metal to be bent will also hinder the bending during the subsequent bending process.

[0042] Therefore, a pressing block 405 is provided at one end of the bending upper mold 402 close to the positioning plate 11, and the pressing block 405 and the top end of the positioning plate 11 are pressed down and matched, and a centering plate 12 is also provided on the circumferential side wall of the rotating rod 9, and the pushing surface of the centering plate 12 is flush with the supporting surface of the support plate 10.

[0043] Connecting blocks 13 are provided on both sides of the top of the positioning plate 11, and an insertion rod 14 is provided at the bottom of the connecting block 13. Slots 15 are provided on one side of the top of the two vertical plates 7 close to the positioning plate 11, and the slots 15 and the insertion rod 14 are matched and plugged in. A lifting spring 16 is provided in the slot 15, and the two ends of the lifting spring 16 are fixedly connected to the bottom of the slot 15 and one end of the insertion rod 14 respectively.

[0044] Strip grooves 17 are formed on both sides of the positioning plate 11 , and tooth blocks 18 are linearly arranged at the lower end of one side of the strip groove 17 , and limiting plates 19 are arranged on both sides of the upper end of the strip groove 17 and away from the vertical plate 7 .

[0045] A rotating shaft 20 is provided at both ends of the rotating rod 9, and the rotating rod 9 is rotatably installed in the movable cavity 8 through the rotating shaft 20. The rotating shaft 20 on the rotating rod 9 close to the positioning plate 11 passes through the vertical plate 7 and extends to the inside of the strip groove 17. A gear 21 is provided at one end of the rotating shaft 20 that passes through the vertical plate 7 and extends to the inside of the strip groove 17. The gear 21 is meshed with the tooth block 18.

[0046] A square block 22 is provided at one end of the gear 21 away from the rotating shaft 20 , and an anti-dropping block 23 is provided at one end of the square block 22 away from the gear 21 . The gap between the square block 22 and the two limiting plates 19 is movable and limited.

[0047] In this embodiment, in the initial state, under the action of the lifting spring 16, the positioning plate 11 is in a lifted state, and the insertion rod 14 is located at the upper end of the slot 15. When the hydraulic column 3 pushes the bending upper mold 402 downward, the clamping column 502 first contacts the sheet metal to be bent, and then clamps and fixes it. At this time, the lower pressing block 405 at one end of the bending upper mold 402 fits the top of the positioning plate 11. As the hydraulic column 3 continues to move downward, the pressure of the clamping column 502 becomes greater and greater, and the positioning plate 11 is also squeezed and moved downward. The positioning plate 11 moves downward through the tooth block 18 to engage the gear 21, thereby causing the rotating rod 9 to rotate, causing the support plate 10 to withdraw from the support for the sheet metal to be bent, and at the same time causing the centering plate 12 to rotate upward, pushing the randomly placed and non-centered sheet metal to be bent to be centered.

[0048] The pushing force of the center plate 12 on the sheet metal to be bent is greater than the extrusion friction force of the extrusion spring 501 on the sheet metal to be bent. Therefore, although the sheet metal to be bent is compressed, it can still be pushed by a larger force to correct the deviation.

[0049] It should be noted that when the centering plate 12 pushes the sheet metal to be bent to the center, the pushing surface of the centering plate 12 and the supporting surface of the support plate 10 are on the same horizontal plane. Therefore, when the bending upper mold 402 presses down to bend the sheet metal, it will not cause obstacles on the bending operation path of the sheet metal.

[0050] In addition, when the centering plate 12 pushes the sheet metal to be bent to the center, the bending upper mold 402 fits against the top of the sheet metal to be bent, and the gear 21 engages with the top tooth of the tooth block 18. At the same time, the two sides of the square block 22 at one end of the gear 21 correspond to the two side walls of the limiting plates 19. At this time, when the bending upper mold 402 moves downward to bend the sheet metal to be bent, it will drive the positioning plate 11 to move downward, so that the two side walls of the limiting plates 19 limit the two sides of the square block 22, so that the rotating rod 20 cannot rotate, thereby allowing the sheet metal to be bent smoothly.

[0051] Among them, why are two limit plates 19 and square blocks 22 needed to be set? If the tooth block 18 extends all the way to the top of the strip groove 17, then the centering plate 12 pushes the sheet metal to be bent to the center, and when the bending upper die 402 is in contact with the top of the sheet metal to be bent, the bending upper die 402 continues to move downward and bend, driving the positioning plate 11 to move downward, thereby engaging the tooth block 18 and the gear 21, so that the centering plate 12 continues to rotate with the rotating rod 9. When the bending upper die 402 extrude and bends the sheet metal to be bent, the centering plate 12 also exerts an extrusion force toward the center on both ends of the sheet metal to be bent, which will cause deformation of the two ends of the sheet metal.

[0052] It should be noted that the thickness of the gear 21 is smaller than the thickness of the strip groove 17 , so that when the square block 22 slides with the two limit plates 19 , the gear 21 will not interfere with the limit plates 19 .

[0053] A controller 24 is disposed on the workbench 1 , and the controller 24 is electrically connected to the hydraulic column 3 , so as to control the operation of the hydraulic column 3 .

[0054] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described one by one here. In the above, welding is preferred for all fixed connections. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and deformations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
