Hub equipped with decorating ring and method for processing the same

Abstract

The invention relates to a wheel spider equipped with a decorative ring, which comprises a wheel hub (1), and a stainless steel decorative ring (2) cladding on the surface of the wheel rim of the wheel hub (1), wherein, the stainless steel decorative ring (2) consists of a decorative wall (21) presenting a bottomless basin shape, and a bending edge (22) positioned at the circumference of the outer side of the decorative wall (21) and bending inward, the decorative wall (21) is tightly fitted with the outer surface of the wheel rim on the wheel spider (1), a bent edge (23) extending inward and adopting a double layer is arranged at the upper end of the bending edge (22), and the bent edge (23) is tightly wrapped together with the surface (11) of the step on the inner side of the wheel rim on the wheel spider (1) through the extrusion method. The invention also discloses a method which enables the decorative ring to be clad on the surface of the wheel rim of the wheel spider (1) by adopting the extrusion process. The stainless steel decorative ring can be firmly compounded on the surface of the wheel rim, and the stainless steel decorative ring is uneasy to wrinkle and scrape.

Description

technical field [0001] The invention relates to a wheel hub provided with a decorative ring and a processing method thereof. Background technique [0002] Electroplated aluminum alloy wheels are favored by car enthusiasts because of their high brightness, wear resistance and fashion, but the production technology requirements are high, the process is complicated, the yield is low, the production cost is high, and it causes serious pollution to the environment. Therefore, it has been gradually developed to wrap a stainless steel decorative ring on the basis of the painted wheel to achieve the effect of electroplating, and the painted wheel spoke plate has a variety of effects to choose from. The front of the ring is easily scratched, and the tightness of the decorative ring is not enough. The decorative ring is easy to loosen under the action of thermal expansion and contraction of the wheel during driving and the force of the whirlwind, and the vehicle will make abnormally h...

AI Technical Summary

Problems solved by technology

The decorative ring first processes the stainless steel plate according to different shapes and specifications of the wheel hub to form a bottomless washbasin-shaped stainless steel ring suitable for the ready-made wheel hub, and then crimps the stainless steel ring on the wheel hub with crimping equipment. Using this processing method to press the stainless steel ring on the wheel hub, it is still a single-layer spinning hemming, and the tightness of the decorative ring is not enough. After a long time, the decorative ring will tear and fall off, which is very unsafe.

[0004] The above-mentioned wheels with stainless steel decorative rings are produced by unilateral stainless steel rolling process, which will produce some defects, such as: wrinkles, scratches on the front need to be polished, and the buckle is not tight, so that the stainless steel decorative rings will Easy to loose and other defects; and when the rolling process uses double-sided stainless steel edging, the rolling process will rebound due to the double-layer stainless steel during production, so that the stainless steel decorative ring cannot be closely matched with the aluminum wheel, resulting in axial and radial to the loose
