Embodiment 1

[0034] Embodiment 1: as figure 1 , figure 2 , image 3 As shown, a composite rim includes a steel ring body 1 and an aluminum alloy web 2, the ring body includes a left ring body 11 and a right ring body 12 coaxially arranged side by side, and the left and right ring bodies They are all made by stamping forming process. The left ring body forms a left connecting ring 111 that is bent and extended inwardly at the edge of the left ring body near one end of the right ring body, and the right ring body is integrally formed with the edge of the left ring body near one end. The right connecting ring 121 is bent and extended inward, and the left and right connecting rings are attached to each other, so that the axial section of the ring body is roughly I-shaped. In order to make the ring body and the panel reliably combined, we can respectively set a number of ring body connection via holes 13 evenly distributed in the circumferential direction on the left and right ring bodies, a...

Embodiment 2

[0038] Embodiment 2: A manufacturing method of a composite rim, which is suitable for manufacturing a composite rim having a steel ring body and an aluminum web as described in Embodiment 1, specifically comprising the following steps:

[0039] a. First punch out a number of ring body connection holes evenly distributed in the circumferential direction on the outer side of the first circular steel plate near the edge through the punching process, and punch out a number of left panel connections on the inner side of the steel plate near the center Via holes; similarly, on another circular steel plate near the edge, punch out a number of ring body connection via holes evenly distributed in the circumferential direction, and punch out a number of right panel connections on the inner side of the steel plate near the center Via. Then, the first steel plate is stretched into a bowl-shaped left ring body with a flat bottom by a stretch forming process, and the other steel plate is st...

Abstract

The invention discloses a compound rim and a manufacturing method thereof. The compound rim comprises a rim body and a center plate, wherein the rim body comprises a left rim body and a right rim body; the left rim body and the right rim body form a left connection ring and a right connection ring which are bent and extended inwards separately through a stamping formation process; a plurality of rim body connection through holes are formed in each of the left rim body and the right rim body; a left center plate connection through hole and a right center plate connection through hole are formed in the left connection ring and the right connection ring separately; the center plate comprises a left center plate and a right center plate which cling to the left connection ring and the right connection ring, and a hoop coated at the outer side of the rim body; axial connection blocks embedded in the left center plate connection through hole and the right center plate connection through hole are formed between the left center plate and the right center plate through a die-cast formation process, and radial connection blocks embedded in the rim body connection through holes are formed between the left center plate and the hoop, and between the right center plate and the hoop separately. The strength of the rim disclosed by the invention can be guaranteed, the production efficiency can be remarkably increased, and the manufacturing cost can be lowered, so that the rim is adaptive to use in vehicles such as all terrain vehicles.

Description

technical field [0001] The invention relates to the technical field of wheel rim manufacturing, in particular to a composite rim and a corresponding 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 relativel...
