The invention discloses a manufacturing process for an automobile aluminum-alloy wheel decorative cover with a small diameter less than 6 inches. The manufacturing process comprises the following steps of I, sawing an aluminum bar with an ordinary sawing machine to obtain a bar blank; II, heating the bar blank to obtain a preheated bar blank; III, preheating a stamping die, and then stamping the preheated bar blank on a punching machine with the preheated stamping die to obtain a decorative cover stamping part; IV, machining the front and back sides of the punch-formed decorative cover stamping part as well as a groove matched with a wheel to sizes as required by a drawing with a numerically controlled lathe, and reserving a small fine machining allowance to obtain a decorative cover machined part; and V, performing surface cleaning and painting, surface lathing and celluloid paint spraying on the decorative cover machined part to obtain an aluminum alloy wheel decorative cover finished product. Through adoption of the manufacturing process, the material utilization rate can be increased effectively; the material loss is reduced; the machining time is saved at the same time; the production efficiency is improved; and the product is dense and uniform in surface and stable in quality.

    本发明公开了一种6英寸以下小直径汽车铝合金车轮装饰盖制作工艺,包括以下步骤:步骤一,使用普通锯床,对铝棒开锯,获得棒料毛坯;步骤二,将棒料毛坯加热,获得预热棒料毛坯;步骤三,将冲压模具预热,之后将其使用在冲床上对预热棒料毛坯进行冲压,获得装饰盖冲压件;步骤四,使用数控车床,将冲压成型的装饰盖冲压件的正、背面及与车轮相匹配的凹槽加工到图纸要求尺寸,留小许余量精加工余量,获得装饰盖机加工件;步骤五,对装饰盖机加工件进行表面清洗喷漆、表面车亮面和喷涂透明油漆处理,获得铝合金车轮装饰盖成品。本发明能有效提高材料利用率,减少材料损耗,同时节省加工时间,提高生产效率;产品表面致密、均匀,质量稳定。
