Description

Technical Field

[0001] The invention relates to a photovoltaic support plate forming device. Background Art

[0002] Photovoltaic support panels are key components in solar photovoltaic power generation systems. They are mainly used to support and fix photovoltaic components (such as photovoltaic panels) to ensure that they can be stably installed on different support structures. Photovoltaic support panels not only have to bear the weight of photovoltaic panels, but also need to be able to resist external environmental factors such as wind, snow load, vibration, etc. to ensure the long-term stability and safety of the photovoltaic system. Photovoltaic support panels are usually installed on roofs, ground or other suitable load-bearing structures. Their design and structure will vary depending on different installation environments and requirements.

[0003] Generally speaking, the basic structure of a photovoltaic support panel includes a middle support structure and a side support structure. The middle support structure is located in the central part of the photovoltaic support panel, and is usually used to enhance the overall strength and rigidity of the support panel and provide a reliable bearing platform for the photovoltaic panel. The side support structure is located on the left and right sides of the photovoltaic support panel. Its main function is to connect adjacent support panels so that multiple photovoltaic support panels can be firmly spliced ​​together to form an overall support frame.

[0004] In the actual application of photovoltaic bracket panels, different installation environments have different requirements for the structural design of the bracket panels. For example, the photovoltaic bracket panels installed on the roof need to consider the roof's load-bearing capacity, inclination angle, and whether they will be affected by extreme weather such as typhoons and blizzards. Therefore, the side support structure of the photovoltaic bracket panel not only needs to be strong enough to support the photovoltaic panel, but also needs to have a certain degree of flexibility to adapt to the shape and displacement of the roof.

[0005] However, there are some limitations in the design and manufacturing process of photovoltaic bracket panels in the prior art, especially in terms of the stability and complexity of the side branch structure. The molding equipment of existing photovoltaic bracket panels is often limited by molds, materials and processes during the processing, resulting in the inability to make the side branch structure more complex and stable. This design limitation directly affects the overall performance of the photovoltaic bracket panel, especially in the face of severe weather or complex installation environments, the side branch structure of the bracket panel is prone to loosening or deformation, thereby affecting the installation stability and service life of the photovoltaic panel.

[0006] Specifically, existing photovoltaic bracket panels usually adopt a relatively simple side branch structure design to adapt to existing molding processes. For example, many photovoltaic bracket panels adopt L-shaped or U-shaped side branch structures. Although these structures can provide sufficient connection strength to a certain extent, they may still have insufficient strength problems when facing strong winds or vibrations. In order to enhance the stability of the side branch structure, some manufacturers will increase the thickness of the bracket plate material or use reinforcements, but these methods often increase the weight and manufacturing cost of the bracket plate, and in some cases, they still cannot fundamentally solve the limitations of the side branch structure design.

[0034] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0035] The molding equipment includes a frame and a molding assembly; the middle part of the molding assembly is used to mold the middle branch structure, the right side of the molding assembly is used to mold the first side branch structure, and the left side of the molding assembly is used to mold the second side branch structure; the right side of the molding assembly is divided into the first right molding area, the second right molding area, the third right molding area and the fourth right molding area along the conveying direction; the equipment uses a combination of multiple molding roller groups and wheel groups to enable the photovoltaic bracket board to be gradually molded in different areas, especially in the first right molding area and the third right molding area, by gradually increasing the ridge height of the molding gap, the profile plate can be gradually molded, avoiding the deformation and stress concentration problems caused by excessive molding in one time in the traditional molding process. This step-by-step molding method can not only ensure the precise molding of the various structural parts of the photovoltaic bracket board, but also reduce the internal stress generated during the processing and extend the service life of the bracket board.

[0036] The Z-shaped forming gap in the second right forming area and the upward and downward bending points in the third right forming area enable the side branch structure to form a more complex geometric shape. A recessed portion is gradually formed in the fourth right forming area. This recessed structure can not only provide a stronger support force for the side branch structure of the bracket plate, but also can be used for the connection between adjacent side branch structures.

[0037] In the concave area of ​​the fourth right forming area, multiple fifth right forming gaps are designed to be gradually deepened concave shapes, so that the profile plate can smoothly form a concave part. The formation process of the concave part is controlled by multiple forming roller groups, so that the depth of the concave part is gradually reduced, ensuring that the profile plate is evenly stressed and deformed stably, thereby avoiding structural failure caused by uneven material deformation.

[0038] In the Z-shaped bending area, multiple sixth right forming gaps are designed in a specific Z-shape, so that the profile plate forms a Z-shaped step on both sides of the flat concave part. This Z-shaped step can play an excellent supporting and fixing role in the structure of the photovoltaic support plate, and is suitable for the connection between adjacent side support structures.

[0039] In the design of the deepening area, multiple seventh right forming gaps gradually deepen and narrow along the conveying direction, so that the recessed parts of the profile plate are further deepened and formed when passing through this area. By gradually deepening, the profile plate can maintain a stable material state during the deformation process, avoiding damage caused by sudden folding or over-forming.

[0040] The eighth right forming gap between the multiple forming roller groups is a vertical groove structure, which gradually narrows along the conveying direction. The main purpose is to flatten the first Z-shaped step formed previously.

[0041] The ninth right forming gap consists of two bending sections: the first bending section is used to bend the first right platform section upward, and the second bending section is responsible for bending the end of the second right platform section downward. This two-way bending design can provide a more complex shape for the profile, making the geometric structure of the photovoltaic bracket board more in line with the mechanical requirements in practical applications.

[0069] The forming assembly includes a plurality of forming roller groups 21 and a plurality of supporting wheel groups 22 arranged at intervals along the conveying direction; the forming roller group 21 includes an upper forming roller 211 and a lower forming roller 212 rotating in opposite directions, and the supporting wheel group 22 includes an upper forming wheel 221 and a lower forming wheel 222 rotating in opposite directions. In this embodiment, the plurality of forming roller groups 21 are arranged at intervals along the conveying direction, and the plurality of supporting wheel groups 22 are arranged at intervals along the conveying direction, and the supporting wheel groups 22 can be arranged continuously or interspersed between two forming roller groups 21. In this embodiment, the plurality of forming roller groups 21 are synchronously driven by a driving mechanism to realize synchronous rotation of the plurality of forming roller groups 21. In this embodiment, the upper forming roller 211 and the lower forming roller 212 of each forming roller group 21 are meshed by gears to realize opposite rotation, and the adjacent upper forming rollers 211 are connected by belts or chains.
