Embodiment 1

[0040] Embodiment 1: as figure 1 As shown, a composite aluminum rim includes a left ring body 1 and a right ring body 2 coaxially arranged side by side, the left ring body is a cylindrical member made by a stamping forming process, and a web is arranged on the right ring body 3. The right ring body and the web are made of an integrated structure through aluminum alloy die-casting process. Similar to the right ring body, the left ring body is also made of aluminum alloy. A connection part 4 is provided on the left side of the right ring body, and the connection part can be an integral structure formed by die-casting with the right ring body, or the connection part can also adopt such as figure 2 , Figure 4 In the structure shown, the connection part includes an embedded section 41 connected to the right coil body, and a welding section 42 protruding from the right coil body. The connection part is made by roll forming process, thereby forming a cylindrical structure with two...

Embodiment 2

[0047] Embodiment 2: A manufacturing method of a composite aluminum rim, which is suitable for manufacturing the composite aluminum rim as described in Embodiment 1, specifically includes the following steps:

[0048] a. Process the cylindrical left ring body through the stamping process, and the two ends of the left ring body are opened, and the left ring body should be made of aluminum alloy. Of course, we can also form a curling on the left end edge of the left ring body to the outer circumferential surface of the left ring body through the curling process, so as to improve the rigidity and strength of the left ring body;

[0049] b. A rectangular aluminum plate is prepared, the rectangular aluminum plate has two short sides and two long sides, and a number of rectangular notches are punched on one of the short sides of the rectangular aluminum plate by a stamping forming process, so that between two adjacent rectangular notches Form the convex rectangular sawtooth, and pu...

Abstract

The invention discloses a composite aluminum rim and a manufacturing method thereof. The composite aluminum rim comprises a left ring body molded by punching, a right ring body molded by die casting and a web plate; a connecting part molded by rolling is arranged in the right ring body; each of the two abutting ends of the connecting part is provided with a plurality of rectangular notches, and rectangular convex blocks adapted to the corresponding rectangular notches; a rectangular sawtooth is formed between every two adjacent rectangular notches; a rectangular groove is formed between every two adjacent rectangular convex blocks; the connecting part comprises an embedded section connected with the right ring body, and a welding section welded with the left ring body; when the right ring body and the web plate are subjected to die-casting molding, the connecting part is connected with a mould core of a die-casting molding mould in a sleeving manner, so that an adjustment gap is formed between the end of each rectangular convex block and the bottom of one corresponding rectangular notch, and an adjustment gap is formed between the end of each rectangular sawtooth and the bottom of one corresponding rectangular groove; and reinforced connecting blocks are formed in the adjustment gaps. With the adoption of the scheme, the intensity of the composite aluminum rim can be guaranteed, the production efficiency can be improved and thus the manufacturing cost is reduced, the quality grade of the composite aluminum rim can be raised effectively, and the composite aluminum rim meets the requirements of a high-quality vehicle.

Description

technical field [0001] The invention relates to the technical field of wheel rim manufacturing, in particular to a composite aluminum rim and a manufacturing method. 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 is a steel rim. This type of rim is rolled into an initial ring body with a certain cross-sectional shape by rolling the steel plate, and then the original ring body The butt joint is welded to form a complete initial ring body, and then the initial ring body is shaped and polished to form a circular ring body with a fixed shape, and then a disc-shaped ring body is pressed into the middle of the inner wall of the circular ring body. The supporting web is provided ...
