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...
