Description

Technical Field

[0001] This utility model belongs to the field of press mold technology, and in particular relates to a press mold for fan manufacturing. Background Technology

[0002] Press molds for wind turbine manufacturing are core process equipment used for stamping and forming various metal parts of wind turbines (such as blades, flanges, and housings). They are usually made of high-strength alloy steel through precision machining and heat treatment, and have high hardness, high wear resistance, and excellent fatigue resistance. Their cavities and structures are specially designed according to the aerodynamic profile and dimensional accuracy requirements of the wind turbine components. During the production process, the molds are installed on a large press, and through the stamping process, the metal sheets are efficiently processed into precision parts, ensuring the aerodynamic efficiency, structural strength, and assembly reliability of the wind turbine components. It is a key process to ensure the performance of wind turbine products and the quality of large-scale production.

[0003] In the existing technology, a metal sheet of a specific size is fed into a large press. Then, the press slide drives the upper die to press down at high speed with huge tonnage pressure. Together with the fixed lower die, the sheet is plastically deformed in the mold cavity, and complex three-dimensional curved surface parts such as fan blades and hubs are formed in one stamping.

[0004] In the existing wind turbine manufacturing field, especially in the press molds used for molding large composite material components, there are still significant technical shortcomings in the design of the lower mold support structure. The specific problems are as follows: 1. Traditional support mechanisms often rely on simple mechanical blocks or local mechanical pads. They lack compatible connection structures with mold bases, placement plates, and other components, and have not formed a standardized disassembly and assembly system. When the lower mold needs to be replaced or maintained, the scattered support units need to be disassembled. The entire process lacks a clear snap-fit ​​positioning structure and unified locking components, resulting in cumbersome and time-consuming disassembly and installation operations. This makes it difficult to meet the production requirements of efficient mold changing. At the same time, repeated disassembly and assembly can easily cause a decrease in the fitting accuracy between the support unit and the mold components, further affecting the stability of subsequent processing.

[0005] 2. Due to the common assembly gaps between support units and the lack of an overall locking mechanism, the support system lacks an overall rigid connection and force flow transmission plan. When the mold is subjected to huge mold closing reaction force, the dispersed support units cannot form a unified force transmission path, the bottom support is not stable enough, and it is impossible to form a unified support whole with sufficient rigidity. This will cause quality problems such as product thickness deviation, residual stress concentration and uneven curing degree, making it difficult to ensure the consistency of the molding of large wind turbine blades and other components and the structural reliability.

[0007] In view of this, the present invention provides a press mold for fan manufacturing, comprising: The base and the placement plate are provided. The top of the base is provided with a slot 4 for engaging a protrusion 1. A engaging plate 1 is fixedly provided on the top of the protrusion 1. Slots 1 are symmetrically opened on both sides of the engaging plate 1. A engaging plate 2 is engaged in both slots 1. Protrusions 2 are fixedly provided on both sides of the top of the engaging plate 2. A slot 3 is opened at the bottom of the placement plate. The protrusions 2 are engaged in the inside of the slot 3. A lower mold is abutted against the top of the placement plate. An upper mold is provided above the lower mold. It also includes a screw, which passes through the base, the first snap-fit ​​plate, the second snap-fit ​​plate and the placement plate in sequence, and is connected to the bottom of the lower mold. A locking nut is threaded on the outer surface of the bottom end of the screw, and the top of the locking nut abuts against the lower surface of the base.

[0008] Furthermore, the bottom sides of the second snap-fit ​​plate are provided with second snap-fit ​​grooves, which are positioned corresponding to the first snap-fit ​​groove. The opening size of the second snap-fit ​​groove is adapted to the thickness of the first snap-fit ​​plate, and the opening size of the first snap-fit ​​groove is adapted to the thickness of the second snap-fit ​​plate. After the second snap-fit ​​groove moves down, it forms a tight snap-fit ​​with the bottom of the inner wall of the first snap-fit ​​groove.

[0009] Furthermore, the second protrusion is configured with a convex structure and is integrally formed with the second snap-fit ​​plate.

[0010] Furthermore, multiple support frames are fixedly installed around the upper surface of the base, and a connecting plate is fixedly connected to the top of the support frame. A hydraulic cylinder is set at the center of the top of the connecting plate, and a receiving plate is fixedly installed at one end of the output shaft of the hydraulic cylinder. An upper mold is fixedly installed at the bottom of the receiving plate.

[0011] Furthermore, a guide rod is fixedly installed between the upper surface of the base and the lower surface of the connecting plate, and the outer surface of the guide rod is slidably connected to the inner wall of the receiving plate.

[0012] Furthermore, a threaded groove is provided inside the bottom end of the lower mold, and the inner wall of the threaded groove is threadedly connected to the outer surface of the screw.

[0013] The beneficial effects of this utility model are: This invention utilizes a multi-interlocking structure consisting of protrusion one and slot four, and protrusion two and slot three, to achieve rapid and precise positioning and assembly between interlocking plate one, interlocking plate two, and placement plate. This effectively ensures the relative positional accuracy between components. Furthermore, the through-bolt and the bottom locking nut together form a locking structure, enhancing the overall structural rigidity and stability of the lower die, resisting eccentric loading and deformation during stamping, and significantly improving the die's impact resistance and service life. It ensures accuracy during die closing, resulting in uniform stress on the workpiece and stable forming quality. Simultaneously, the overall structure is easy to disassemble and maintain; loosening the locking nut allows for quick disassembly of each component, greatly improving the efficiency of die maintenance and replacement.

[0021] like Figures 1 to 4 As shown, a press mold for manufacturing fans includes, The base 1 and the placement plate 14 are provided. The top of the base 1 is provided with a slot 20 for engaging a protrusion 9. A card 8 is fixedly provided on the top of the protrusion 9. Slots 10 are symmetrically opened on both sides of the card 8. Card plates 21 are engaged in both slots 10. Protrusions 23 are fixedly provided on both sides of the top of the card 21. A slot 3 15 is opened at the bottom of the placement plate 14. Protrusions 23 are engaged in the inside of the slot 3 15. The top of the placement plate 14 abuts against a lower mold 16. An upper mold 6 is provided above the lower mold 16. It also includes a screw 17, which passes through the base 1, the first snap-fit ​​plate 8, the second snap-fit ​​plate 11 and the placement plate 14 in sequence, and is connected to the bottom of the lower mold 16. A locking nut 18 is threaded on the outer surface of the bottom end of the screw 17, and the top of the locking nut 18 abuts against the lower surface of the base 1.

[0022] This application utilizes a multi-interlocking structure between the base 1, interlocking plate 8, interlocking plate 11, and placement plate 14, combined with the fastening effect of screw 17 and locking nut 18, to achieve rapid assembly and stable connection of various components. This significantly improves the overall structural stability and assembly efficiency of the mold, facilitates rapid disassembly and maintenance of the mold, and effectively adapts to the frequent adjustment requirements of the mold during the fan manufacturing process. At the same time, the interlocking of the slot 4 20 on the top of the base 1 with the protrusion 9, the interlocking of the slot 10 on the interlocking plate 8 with the interlocking plate 11, and the interlocking of the protrusion 13 on the interlocking plate 11 with the slot 3 15 on the placement plate 14 forms a multi-dimensional positioning structure, ensuring the accuracy of the assembly of each component and thus improving the installation accuracy of the lower mold 16.

[0023] As a preferred example of this application, the bottom sides of the snap-fit ​​plate 2 11 are provided with snap-fit ​​grooves 2 12, which are positioned corresponding to the snap-fit ​​groove 10. The opening size of the snap-fit ​​groove 2 12 is adapted to the thickness of the snap-fit ​​plate 1 8, and the opening size of the snap-fit ​​groove 10 is adapted to the thickness of the snap-fit ​​plate 2 11. After the snap-fit ​​groove 2 12 is moved down, it forms a tight snap-fit ​​with the bottom of the inner wall of the snap-fit ​​groove 10.

[0024] This application achieves a tight snap-fit ​​by having the second slot 12 and the first slot 10 correspond in position and by using a specific dimensional design. When the second snap-fit ​​plate 11 moves down to make the second slot 12 and the bottom of the inner wall of the first slot 10 snap tightly together, this connection method can effectively limit the relative movement of the second snap-fit ​​plate 11 and the first snap-fit ​​plate 8 in the horizontal and vertical directions. During the operation of the mold of the press used in the manufacturing of the fan, it will be subjected to a large pressure and impact force. This stable snap-fit ​​structure can prevent the components from loosening or separating due to the force, ensuring the stability of the overall structure of the mold, thereby improving the processing accuracy and quality of the fan parts.

[0025] As a preferred example of this application, the second protrusion 13 is provided with a convex structure and is integrally formed with the second snap-fit ​​plate 11.

[0026] This application reduces the connection points and potential loosening points between components by integrally molding the second protrusion 13 and the second snap-fit ​​plate 11, thereby improving the overall integrity and strength of the structure. At the same time, the integral molding design also simplifies the manufacturing process, reduces production costs, and improves the reliability and service life of the components.

[0027] As a preferred example of this application, a plurality of support frames 2 are fixedly installed around the upper surface of the base 1. A connecting plate 3 is fixedly connected to the top of the support frame 2. A hydraulic cylinder 4 is provided at the center of the top of the connecting plate 3. A receiving plate 5 is fixedly installed at one end of the output shaft of the hydraulic cylinder 4. An upper mold 6 is fixedly installed at the bottom of the receiving plate 5.

[0028] This application utilizes multiple support frames 2 fixedly installed around the upper surface of the base 1 to form a stable frame structure with the connecting plate 3 at the top. This provides a solid installation foundation for upper components such as the hydraulic cylinder 4 centrally located at the top of the connecting plate 3, enhancing the overall load-bearing capacity and structural rigidity of the press mold. It can withstand the large impact force generated during press operation, ensuring the safe and stable operation of the equipment. Furthermore, the receiving plate 5 fixedly installed at one end of the output shaft of the hydraulic cylinder 4 is fixedly connected to the upper mold 6 at the bottom, allowing the driving force of the hydraulic cylinder 4 to be evenly transmitted to the upper mold 6. This ensures that the upper mold 6 is subjected to balanced force during the stamping process, which helps to improve the forming accuracy of fan parts. At the same time, it facilitates precise control of the movement stroke and pressure of the upper mold 6 through the hydraulic cylinder 4 according to different processing requirements, thus improving the applicability of the mold.

[0029] As a preferred example of this application, a guide rod 7 is fixedly installed between the upper surface of the base 1 and the lower surface of the connecting plate 3, and the outer surface of the guide rod 7 forms a sliding connection with the inner wall of the receiving plate 5.

[0030] This application uses a guide rod 7 fixedly installed between the upper surface of the base 1 and the lower surface of the connecting plate 3. Its outer surface forms a sliding connection with the inner wall of the receiving plate 5, which provides precise guidance for the descent process of the receiving plate 5 and the upper mold 6. This effectively avoids the upper mold 6 from tilting or shaking during the movement, ensures that the upper mold 6 and the lower mold 16 can be accurately aligned, improves the accuracy of stamping, and reduces the scrap rate of parts caused by alignment deviation.

[0031] As a preferred example of this application, a threaded groove 19 is provided inside the bottom end of the lower mold 16, and the inner wall of the threaded groove 19 is threadedly connected to the outer surface of the screw 17.

[0032] This application achieves a stable fixation of the lower mold 16 to the overall structure by forming a threaded connection between the threaded groove 19 inside the bottom end of the lower mold 16 and the outer surface of the screw 17. It also facilitates the quick replacement of the lower mold 16 according to the processing requirements of different fan parts, thereby improving the versatility and flexibility of the mold and reducing the time cost and labor intensity of mold replacement.

[0033] Working principle: When assembling the overall structure, place the base 1 stably in the work area. Then, insert the screw 17 through the pre-drilled hole at the bottom of the base 1, so that its top end extends beyond the upper surface of the base 1. Align the protrusion 9 with and snap it into the slot 20 at the top of the base 1. Next, align the mounting hole at the bottom of the snap-fit ​​plate 8 with the protrusion 9 and fix it in place, while ensuring that the screw 17 passes through the through hole in the center of the snap-fit ​​plate 8. Align the slots 12 at the bottom of the two snap-fit ​​plates 11 with the slots 10 on both sides of the snap-fit ​​plate 8, and then snap the snap-fit ​​plates 11 into the slots 10 from top to bottom, ensuring that the screw 17 passes through the corresponding hole on the snap-fit ​​plate 11. Pick up the placement plate 14 and align the slot 3 15 inside it with the protrusion 13 at the top of the installed snap-fit ​​plate 11. Then, place the placement plate 1... 4. Press down to make the second protrusion 13 fully engage with the third slot 15, while ensuring that the screw 17 passes through the center hole of the placement plate 14. Under the base 1, screw the locking nut 18 into the bottom end of the screw 17. Tighten the locking nut 18 with a tool. The preload generated by the screw 17 will press the placement plate 14, the second snap plate 11, the first snap plate 8 and the base 1 into a high-rigidity whole in sequence, eliminating the assembly gap between the components. Finally, align the threaded groove 19 at the bottom of the lower mold 16 with the top of the screw 17, rotate the lower mold 16 to screw it in and fasten it to the screw 17, forming the final forming working surface. During use, ensure the entire area is clean and free of foreign objects, check that the locking nut 18 is tightened, and ensure the rigidity and reliability of the entire lower die support system. Place the metal sheet to be stamped on the predetermined position of the lower die 16, start the hydraulic system of the press, and the control system issues a command to drive the hydraulic cylinder 4 to work. The output shaft of the hydraulic cylinder 4 pushes the receiving plate 5 and the upper die 6 to descend smoothly and vertically along the guide direction of the guide rod 7. The upper die 6 contacts the sheet placed on the lower die 16 and applies huge pressure, causing the sheet to undergo plastic deformation in the die cavity, forming the fan component of the required shape. The upper die 6 can hold pressure briefly at the end of the stroke to ensure that the shape of the workpiece is fully stabilized. Subsequently, the hydraulic cylinder 4 drives the upper die 6 to rise along the guide rod 7 back to the initial position. The operator or automated equipment removes the formed workpiece from the lower die 16.

[0034] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
