specific Embodiment approach 1

[0026] Specific implementation mode one: as figure 1 As shown, this embodiment discloses a carbon fiber three-piece combined rim, including an inner rim 3, an outer rim 2 and a spoke 1, and the inner end surface of the outer rim 2 and the outer end surface of the inner rim 3 are connected by high-strength glue. The rim body is formed by adhesive sealing fixed connection, the inner end of the spoke 1 is provided with a central boss, the central boss of the spoke 1 is arranged in the center cavity of the rim body, and the spoke 1 is connected with the rim body (through bolts and lock nuts). ) locking connection (the spoke 1, the outer rim 2 and the inner rim 3 are locked and fixed with bolts and lock nuts, and after inspection, the formed rim can be applied to the actual vehicle).

specific Embodiment approach 2

[0027] Specific implementation mode two: as Figure 1-Figure 7 As shown, this embodiment discloses a molding die for a carbon fiber three-piece composite rim described in Embodiment 1, the molding die includes an outer rim die set and an inner rim die set; the outer rim die set and The inner rim mold group is coaxially arranged, and the outer rim mold group includes an upper mold 7, a lower mold 6, a parting block 8, a parting nut 9, a lifting block 5 and a lifting nut 4; the inner rim mold The group includes a mold cover 13, a round tube outer mold 15, a round tube inner core 17, a round cake inner core 18 and a mold bottom 16;

[0028] The lower surface of the upper mold 7 is provided with an annular boss, the annular boss is coaxially arranged with the upper mold 7, the middle part of the annular boss forms a cylindrical groove, and the middle part of the cylindrical groove of the upper mold 7 is provided with a platform. The shoulder through hole is embedded with a partin...

specific Embodiment approach 3

[0030] Specific implementation mode three: as figure 2 , image 3 As shown, this embodiment is a further description of the second specific embodiment. The lower end surface of the upper mold 7 is located on the non-forming surface and is provided with a positioning through hole 1, and the upper end surface of the lower mold 6 is located on the non-forming surface. There are two positioning through holes. The first positioning through hole is coaxial with the second positioning through hole and has the same diameter. Alignment (Considering the valve protruding, the alignment must be ensured when the upper and lower molds are closed, by inserting cylindrical pins into the positioning through hole 2 of the lower mold 6 and the positioning through hole 1 of the upper mold 7 to ensure the alignment of the upper and lower molds when closing the molds) .

Abstract

The invention relates to a carbon fiber three-piece combined rim and a forming die thereof, and relates to the field of rims and forming dies thereof. The carbon fiber three-piece combined rim is characterized in that the inner end surface of an outer rim and the outer end surface of an inner rim are fixedly connected through high-strength adhesive to form a rim body, a central boss is arranged at the inner end of a spoke, the central boss of the spoke is arranged in a central cavity of the rim body, and the spoke is connected with the rim body in a locking mode. The forming die comprises an outer rim die set and an inner rim die set, when an upper die and a lower die of the outer rim die set are compounded, a cavity which is consistent with the contour shape of the outer rim to be manufactured is formed between the top surface of an annular boss of the upper die and the groove bottom surface of an annular inner groove of the lower die, and is used for forming the contour of the outer rim; and an inner core of a round pipe of the inner rim die set is arranged coaxial with a die cover and the inner core of the round cake, and carries out mutual insertion for positioning operation, and a round pipe outer die is arranged coaxial with the mold cover, and carries out mutual insertion for positioning operation. The forming die is used for forming the carbon fiber rim.

Description

technical field [0001] The invention relates to the field of wheel rims and forming molds thereof, in particular to a carbon fiber three-piece composite wheel rim and forming molds thereof. Background technique [0002] Carbon fiber reinforced polymer composite materials are a series of high-performance composite materials prepared with carbon fiber as reinforcement, resin as matrix, and special molding and processing methods for advanced composite materials. Because the composite material has high specific strength and specific modulus, fatigue resistance and corrosion resistance, it has been more and more used in automobile parts in recent years. Compared with traditional steel or aluminum rims, carbon fiber rims are stronger and lighter than aluminum rims, so that they can meet the requirements of high lightness and lightweight. [0003] For carbon fiber rims, the design and manufacture of single-piece rims is difficult and difficult to form, while the forming of three-p...
