Abstract

The invention discloses a color register process for a wheel hub. The process sequentially comprises the following steps of: (1) performing surface treatment; (2) spraying powder; (3) grinding the wheel hub, and removing parts where more powder is sprayed; (4) spraying paint; (5) machining by using a cutter; (6) putting into paint tanks, and performing color register on the wheel hub for the first time through cathode electrophoresis; and (7) sequentially repeating step (5) and step (6), machining different parts of the wheel hub by using the cutter, and performing color register for multiple times in the paint tanks of different colors every time. By the process, different parts of the wheel hub can be machined and painted for multiple times, the wheel hub has different patterns, modelings and colors, the diversified demand of customers is met, and the technical problems are solved; and the process has good popularization and application value.

Description

(1) Technical field [0001] The invention relates to a coloring process for a wheel hub. (2) Background technology [0002] At present, in the wheel hub industry, coloring is mainly done through overall painting. According to the current state of the industry, the color of the wheel hub can only be changed by changing the paint color. It is impossible to achieve more than two colors on the same wheel hub, and it is impossible to make a pattern. (3) Contents of the invention [0003] The purpose of the present invention is to aim at the deficiencies of the prior art, and to provide a wheel tinting process which can make the wheel have various colors and patterns. [0004] The technical scheme adopted in the present invention is: [0005] A coloring process for wheel hubs comprises the following steps in turn: [0006] (1) Surface treatment: Pre-treatment is carried out after rough grinding of the wheel hub, including degreasing-water washing-surface conditioning-chromating...
