Iron-aluminum composite steel ring and manufacturing method thereof

Abstract

The invention discloses an iron-aluminum composite steel ring and a manufacturing method thereof. The iron-aluminum composite steel ring comprises a left ring body, a right ring body and a center plate. The left ring body is produced by press forming process, the right ring body and the center plate are produced by aluminum alloy compression molding process, the right ring body is internally provided with a transition ring body; the transition ring body comprises an embedding section and a welding section, wherein the embedding section is connected with the right ring body, and the welding section extends out of the right ring body; when the right ring body and the center plate are produced by compression molding, the transition ring body is served as an embedding piece of a compression molding mold, so that the embedding section located at the right end of the transition ring body is embedded in the right ring body; a shaft sleeve is connected with the right end of the left ring body and the welding section extended out of the right ring body of the transition ring body, and the left ring body and the welding section of the transition ring body are connected and integrated through a welding process; a roll rim is arranged on the edge of the left end of the left ring body, wherein the roll rim turns and rolls towards the circumferential surface of the outer side of the left ring body. According to the iron-aluminum composite steel ring and the manufacturing method thereof, not only can strength of a vehicle rim be guaranteed, and is production efficiency significantly improved to reduce the manufacturing cost, but also the quality grade can be effectively improved to adapt the requirement of high-quality vehicle.

Description

technical field [0001] The invention relates to the technical field of wheel rim manufacturing, in particular to an iron-aluminum composite steel rim and a manufacturing method thereof. Background technique [0002] The rims used for the wheels of existing ATVs, golf carts, lawns and garden machines etc. usually include an annular ring body, a supporting web connected to the ring body, and the supporting web is provided with an axle hole so that connected to the axle. The rim is usually made of the following two materials. The first one is aluminum alloy rim, which is integrally cast by aluminum alloy die-casting process. Although this type of aluminum alloy rim has the advantages of high production efficiency, light weight and beautiful appearance, However, due to the technical limitations of the die-casting process, the shape and structure of the rim are relatively simple, which cannot meet people's requirements for some complex-shaped rims. In particular, its cost is re...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems of low production efficiency and difficulty in meeting the requirements of high-quality vehicles in existing steel rims, as well as the high price and difficulty in manufacturing complex-shaped rims in aluminum alloy rims. Provide an iron-aluminum composite steel ring and its manufacturing method, which can not only ensure the strength of the rim, significantly improve production efficiency and reduce manufacturing costs, but also effectively improve its quality grade to meet the requirements of high-quality vehicles
