Problems solved by technology

[0005] When the former rim structure is extruded or spun on the weld, it is easy to crack at the weld, which increases the production cost and has high instability factors; the latter rim structure can only be formed by a die-casting mold A kind of aluminum ring, the rim style is limited, if different styles of rims are required, different molds need to be used, which increases the cost of the mold, and the overall structure needs to be improved.

Embodiment Construction

[0033] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the embodiments and accompanying drawings. The embodiments are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0034] First please refer to Figure 1 to Figure 7 , a wheel spinning manufacturing method provided by the present invention,

[0035] It contains the following steps:

[0036] (a) preparing an aluminum alloy material;

[0037] (b) forging the aluminum alloy material into a rough rim 10, the rough rim 10 is integrally formed with a rim 20 and a rib 30, the rib 30 is formed on the inner edge of the rim 20, and the rim 20 is integrally formed. The sectional shape of the rim 20 and the rib 30 is a Y shape;

[0038] (c) The two molds 40, 41 are clamped respectively on both sides of the rim rough blank 10, and the inner edges of each of the molds 4...

Abstract

The invention discloses a wheel hub spinning manufacturing method. The method comprises the steps of (a) preparing an aluminum alloy material; (b) forging the aluminum alloy material into a wheel hub rough blank, the wheel hub rough blank is provided with a wheel rim and a rib part in an integrally formed mode, and the rib part is formed on the inner edge of the wheel rim; (c) the two sides of the wheel hub rough blank are clamped by two dies correspondingly; and (d) the two sides of the wheel rim of the wheel hub rough blank are spun by using a spinning device so as to form two rib arms in preset shapes, namely so as to form a wheel hub finished product. According to the method, by means of the parts, the wheel hub rough blank is provided with the wheel rim and the rib part which are in a Y shape in an integrally formed mode and is clamped by the dies, the two rib arms are formed on the two sides of the wheel rim in a spinning mode, the structure strength is high, and therefore the wheel hub forming can be diversified, the production efficiency can be improved, and the cost can be reduced.

Description

technical field [0001] The invention relates to a wheel rim spinning manufacturing method, in particular to a wheel rim manufacturing method that is used on both sides of the forged rim rough blank rim to make the wheel rim more diverse and cost-effective. Background technique [0002] The forming method of general rim structure can be roughly divided into extrusion form or casting type two big classes, and the rim forming method of known extrusion form, as the improvement of rim structure disclosed in domestic No. 094204918 new patent, is installed in the automobile The rim includes a rim, a rim and a rib, wherein the rim is the peripheral edge protruding on both sides of the rim for tire bonding, and the rib is the inner edge on one side of the rim for the wheel The improvement lies in: the rim is integrally formed with aluminum alloy plate with rim and rib, by making the same cross-sectional shape as the rim according to the required cross-sectional shape of the rim, and ...
