Embodiment 1

[0039] Embodiment 1: as figure 1 , figure 2 , image 3 As shown, an iron-aluminum composite steel ring includes a ring body, the ring body includes a left ring body 1 and a right ring body 2 coaxially arranged side by side, and the left ring body is a steel cylinder made by a stamping forming process The right ring body is provided with a panel 3, and the right ring body and the panel are made into an integrated structure through an aluminum alloy die-casting process. A transition ring body 4 is arranged on the left side of the right ring body. The transition ring body includes a The connected embedded section 41 and the welding section 42 protruding from the right ring body, the transition ring body is also a steel cylindrical member made by stamping and forming process. When the right ring body and the panel are die-casted, the transition ring body is used as an insert of the die-casting mold, so that the embedded section at the right end of the transition ring body is em...

Embodiment 2

[0044] Embodiment 2: A method for manufacturing an iron-aluminum composite steel ring, which is suitable for manufacturing the iron-aluminum composite steel ring described in Embodiment 1, specifically comprising the following steps:

[0045] a. First process the cylindrical left ring body and the transition ring body through the stamping process. The transition ring body includes a cylindrical welding section and a conical embedded section that expands outwards, and the embedded section A number of connecting through holes evenly distributed in the circumferential direction are punched out, and at the same time, the edge of the left end of the left coil body is turned over by the curling process to produce the everted curl;

[0046] b. Such as Figure 4As shown, the cylindrical welding section of the transition ring body is sleeved on the mold core 61 of the lower mold 6 of the aluminum alloy die-casting mold installed on the die-casting machine, and the upper mold 5 and the...

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...
