Description

Technical Field

[0001] This application belongs to the field of busbar processing technology, and particularly relates to a pressing and positioning structure and pressing equipment for composite busbars. Background Technology

[0002] Laminated busbars are widely used as high-end power electronic connectors. Common composite busbars are generally made by lamination process in one step. During the hot pressing process, the fixed positioning pins used often cause mutual compression between the positioning pins and the inner wall of the hole due to the inconsistency between the mold material and the product's coefficient of thermal expansion and contraction. As a result, the inner wall of the product is inevitably damaged and the product gets stuck when unmolding, which poses potential product quality risks and operational difficulties. Utility Model Content

[0003] This application provides a pressing and positioning structure and pressing equipment for composite busbars to solve the technical problems of quality hazards and inaccurate positioning of composite busbars during hot pressing.

[0005] The positioning template has multiple positioning holes arranged at intervals;

[0006] The unloading template is supported on the positioning template and is used to support the composite busbar.

[0007] Each positioning hole contains a guide component, which is vertically installed. When the composite mother is placed on the unloading template, the end of the guide component that is away from the positioning template guides the guide through the mounting hole.

[0008] Optionally, the guide component includes a guide pin and a guide sleeve fitted around the outer periphery of the guide pin. The outer diameter of the guide sleeve is adapted to the inner diameter of the mounting hole. The guide sleeve is located on the outer periphery of the positioning hole.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] like Figure 1 As shown, this application provides a positioning structure for pressing a composite busbar 5. The structure includes a positioning module 1, a stripping template 4, and guide members. The positioning module 1 has multiple spaced positioning holes for precisely positioning the mounting holes of the composite busbar 5. The stripping template 4 is supported on the positioning module 1 to support the composite busbar 5. A guide member is vertically installed in each positioning hole, with one end of the guide member facing away from the positioning module 1 guiding through the mounting hole to ensure accurate alignment of the composite busbar 5 during the pressing process.

[0026] In this embodiment, the surfaces of the positioning module 1 and the unloading template 4 are arranged parallel to each other and fixed by a detachable connection, facilitating the switching between composite busbars 5 of different sizes. The guide component not only improves the installation accuracy of the composite busbar 5 but also reduces pressing defects caused by inaccurate positioning. This structure enables the composite busbar 5 to achieve rapid positioning and efficient pressing during the pressing process, significantly improving production efficiency and product quality.

[0027] Furthermore, the shapes of the positioning module 1 and the unloading template 4 can be customized according to the shape of the composite busbar 5 to accommodate busbars of different shapes. For example, for a rectangular busbar, the positioning module 1 and the unloading template 4 can be designed as rectangles, while for a circular busbar, they can be designed as circles. In addition, the dimensions of the positioning module 1 and the unloading template 4 can also be adjusted according to the dimensions of the composite busbar 5 to ensure that they can completely cover the mounting holes of the busbar during the pressing process, thereby improving the accuracy of positioning.

[0028] In terms of connection method, the positioning module 1 and the unloading template 4 can be fixed by bolts, clips, or other mechanical connection methods. This detachable connection method not only facilitates installation and disassembly, but also allows for quick replacement of damaged parts when needed, reducing maintenance costs.

[0029] In some embodiments, the guide includes a guide pin 2 and a guide sleeve 3 fitted around its outer periphery. The outer diameter of the guide sleeve 3 is adapted to the inner diameter of the mounting hole to ensure a tight fit during the pressing process. The guide pin 2 is adapted to the positioning hole and one end is riveted into the positioning hole, thereby fixing the guide.

[0030] Furthermore, the guide sleeve 3 can be made of stainless steel or polytetrafluoroethylene (PTFE). Stainless steel has high strength and good corrosion resistance, making it suitable for long-term use in industrial environments; while PTFE has a low coefficient of friction and good self-lubricating properties, which can reduce wear between the guide and the mounting hole during the pressing process. In addition, the diameter of the guide pin 2 ranges from 3mm to 6mm and can be adjusted according to the thickness of the composite busbar 5 and the size of the mounting hole to ensure the strength and stability of the guide.

[0031] In practical applications, the shape of the guide component can be designed according to the shape of the mounting hole. For example, for a circular mounting hole, the guide sleeve 3 can be designed as a cylinder; while for an oblong mounting hole, it can be designed as an oblong column. This shape-adaptive design not only improves the versatility of the guide component but also allows for flexible adjustment according to different application scenarios.

[0032] Through the above technical solutions, the optimized guide structure of this embodiment not only improves the pressing accuracy of the composite busbar 5, but also further enhances the durability and versatility of the guide through material selection and shape adaptation design, providing strong support for the high-quality production of the composite busbar 5.

[0033] In some embodiments, the length of the guide pin 2 is greater than the length of the guide sleeve 3, and the difference in length between the two ranges from 1mm to 2mm. This design not only ensures the stability and guiding accuracy of the guide component within the mounting hole, but also provides sufficient space for the pressing of the composite busbar 5.

[0034] In this embodiment, the length difference between the guide pin 2 and the guide sleeve 3 can be adjusted according to the thickness of the composite busbar 5 and the depth of the mounting hole. For example, for a thicker composite busbar 5, the length difference can be appropriately increased to ensure that the guide can completely penetrate the mounting hole and provide sufficient guidance. For a thinner composite busbar 5, the length difference can be reduced to avoid installation difficulties caused by an excessively long guide.

[0035] In practical applications, the length difference of the guide component can be optimized in conjunction with the production process of the composite busbar 5. For example, in an automated pressing production line, a larger length difference can improve the installation efficiency of the guide component and reduce manual intervention; while in the manual pressing process, a smaller length difference can improve the guiding accuracy and reduce errors caused by human operation.

[0036] Through the above technical solution, the optimization of the guide length difference in this embodiment not only improves the pressing accuracy and efficiency of the composite busbar 5, but also further enhances the durability and versatility of the guide by combining material selection and production process, providing reliable technical support for the high-quality production of the composite busbar 5.

[0037] In some embodiments, the outer peripheral wall shape of the guide sleeve 3 is consistent with the inner peripheral wall shape of the mounting hole. This design not only improves the fit between the guide sleeve 3 and the mounting hole, but also reduces the pressing deviation caused by excessive gap.

[0038] In this embodiment, the shape of the outer peripheral wall of the guide sleeve 3 can be customized according to the shape of the mounting hole. For example, for a circular mounting hole, the guide sleeve 3 can be designed as a cylinder, with its outer diameter matching the inner diameter of the mounting hole; while for an oblong mounting hole, it can be designed as an oblong column. This shape adaptation design not only improves the versatility of the guide sleeve 3, but also allows for flexible adjustment according to different application scenarios.

[0039] Furthermore, the material selection of the guide sleeve 3 also has a significant impact on the pressing accuracy and service life. The guide sleeve 3 can be made of stainless steel or polytetrafluoroethylene (PTFE). Stainless steel has high strength and good corrosion resistance, making it suitable for long-term use in industrial environments; while PTFE has a low coefficient of friction and good self-lubricating properties, which can reduce wear between the guide sleeve 3 and the mounting hole during the pressing process. In some embodiments, the unloading template 4 has a clearance notch to avoid the guide component. This design not only provides sufficient space for the guide component but also ensures the parallel spacing between the unloading template 4 and the positioning module 1.

[0040] In this embodiment, the surfaces of the unloading template 4 and the positioning module 1 are arranged parallel to each other and fixed by a detachable connection. This design not only facilitates switching between composite busbars 5 of different sizes, but also allows for quick replacement of damaged parts when needed, reducing maintenance costs. The shape and size of the clearance notch can be adjusted according to the shape and size of the guide to ensure that the guide can smoothly pass through the mounting hole and achieve precise positioning.

[0041] Furthermore, the material of the unloading template 4 can be either high-strength aluminum alloy or stainless steel. Aluminum alloy has low density and good processing performance, making it suitable for lightweight designs; while stainless steel has high strength and good corrosion resistance, making it suitable for long-term use in industrial environments. In addition, the thickness of the unloading template 4 can be adjusted according to the weight of the composite busbar 5 and the pressing pressure to ensure sufficient support force during the pressing process.

[0042] In some embodiments, the unloading template 4 is connected to the positioning module 1 around its perimeter by multiple connectors 6. This connection method not only ensures the stability between the two but also facilitates quick disassembly and replacement, improving production efficiency and equipment flexibility. In specific implementations, these connectors 6 can be bolts, clips, or other mechanical connection devices. The number and position of the connectors 6 can be adjusted according to the dimensions of the unloading template 4 and the positioning module 1 to ensure the connection strength and stability between them. In this embodiment, the connectors 6 are preferably high-strength bolts, which have good tensile and shear strength and can effectively withstand the pressure generated during the pressing process. The bolted connection design also allows for quick disassembly and replacement of the template when needed, facilitating the maintenance and replacement of templates of different specifications to accommodate composite busbars 5 of different sizes.

[0043] In some implementations, the positioning module 1 is made of aluminum plate or steel plate. Aluminum plate is lightweight, easy to process, and highly corrosion-resistant, making it suitable for scenarios where lightweight equipment is a high priority; while steel plate has high strength, high rigidity, and good wear resistance, making it suitable for scenarios where positioning accuracy and structural strength are high priority.

[0044] Specifically, the positioning module 1 made of aluminum plate can achieve a high-precision positioning hole layout through precision machining, and its surface can be further improved with anodizing treatment to enhance wear resistance and corrosion resistance. The positioning module 1 made of steel plate can ensure the accuracy of the positioning holes through high-precision CNC machining, and its corrosion resistance can be improved through surface plating treatment (such as zinc plating or chrome plating).

[0045] In practical applications, the material selection and structural design of positioning module 1 can be further optimized according to specific needs. For example, for high-precision composite busbar 5 pressing, high-strength aluminum alloy (such as 7075 aluminum alloy) can be used as the material of positioning module 1, which has high strength and good processing performance, and can meet the requirements of high-precision positioning. For scenarios requiring higher rigidity and wear resistance, high-strength alloy steel (such as 45 steel) can be used as the material of positioning module 1, and its hardness and wear resistance can be further improved through heat treatment processes.
