Embodiment Construction

[0023] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with specific embodiments.

[0024] The present invention comprises following steps:

[0025] A. Dusting. First heat the hub and then spray powder; after powder spraying, solidify, cool and polish in sequence. The heating temperature is 100-110°C. The curing temperature is 140-160°C, and the curing time is 18-22 minutes.

[0026] B. Spraying paint for the first time; firstly heat the wheel hub and then spray paint, and then solidify, cool and polish the wheel hub in sequence after painting. The heating temperature is 140-160°C. The curing temperature is 190-210°C, and the curing time is 25-27 minutes. Sand with 200-grit sandpaper first, then 800-grit sandpaper.

[0027] C. Polishing: use frequency conversion technology to control the speed of the polishing machine, so that ...

Abstract

The invention discloses a vehicle hub machining process. The vehicle hub machining process is characterized by comprising the steps of (A) powder spraying, (B) primary paint spraying, (C) polishing, (D) wire drawing for inner rims, (E) wire drawing for front surfaces of hubs and (F) secondary paint spraying. The vehicle hub machining process with the steps sprays paint after wire drawing of the surfaces of the hubs, so that the third dimension and the texture of aluminum alloy hubs are greatly improved; and paint surfaces are stable and not easy to fall, so that the appearance quality of the hubs is improved.

Description

technical field [0001] The invention relates to a process for processing the appearance of an automobile wheel hub. Background technique [0002] my country's car modification industry is in its infancy. Following the adjustment of the annual inspection time for new cars, national regulations and standards for car modification will be promulgated one after another in the next one to two years. [0003] A very important step in car modification is to replace the wheel hub. Generally, due to cost or audience reasons, the appearance of original wheels is mostly ordinary, which cannot show the personality of young people. Therefore, as people's requirements for products are getting higher and higher, full-size aluminum alloy wheels are gradually emerging in the market today. However, the existing wheel appearance processing technology cannot show the texture of the aluminum alloy wheel, and cannot meet the requirements of consumers. Contents of the invention [0004] In vie...
