Embodiment Construction

[0033] The present invention will be further described below in conjunction with the examples.

[0034] Such as figure 1 , 2 Shown, the motorcycle wheel hub composite electroplating method comprises the following steps:

[0035] a. Adopt metal mold to cast a motorcycle aluminum alloy wheel hub blank of predetermined shape, but various irregular geometric shapes or regular geometric shapes, this process is not limited by the shape of motorcycle hub; the wheel hub of this embodiment is figure 1 Shape, hatching area is electroplating area, other area is painting area, for rough machining:

[0036] 1) Fine grinding: Use different types of sandpaper to smooth out the burrs, particles, impurities, etc. on the surface of the hub to make the surface of the hub smooth;

[0037] Specifically, after heat treatment and solid solution aging, sandpapers of different thicknesses are used to polish in sequence to make the surface smooth, and then sandblasting is carried out with steel shot...

Abstract

The invention provides a motorcycle hub composite electroplating method. The problems of the low production rate, the high processing cost and the poor generality of an existing hub composite electroplating method are solved. The motorcycle hub composite electroplating method comprises the following steps that a, the rough machining is conducted on a motorcycle hub billet, the machining allowanceis left in the electroplating area, and other areas are machined into the finished product size; b, coating and spraying are conducted on the rough-machined billet; c, the fine machining is conductedon the electroplating area, the allowance of the electroplating area is turned off, and an aluminum alloy matrix is exposed; d, the pre-treatment washing before electroplating is conducted to remove the oil stains and the dust from the surface; e, a plurality of nickel is electroplated on the fine machined area; and f, the chrome is electroplated on the basis of the electroplating of the multi-layer nickel. The motorcycle hub composite electroplating method is widely used in the technical field of hub surface treatment.

Description

technical field [0001] The invention relates to an electroplating method, in particular to a composite electroplating method for a motorcycle hub. Background technique [0002] At present, there are three main processes for the surface treatment of motorcycle wheels: [0003] 1. Spraying process: currently the most widely used surface treatment method, the surface of the wheel hub is directly sprayed with a layer of powder, or sprayed with a base powder and then sprayed with a layer of color paint, and then sprayed with base powder and then sprayed with color paint, and then Spray another coat of varnish powder. Three kinds of spraying are classified as spraying process. The cost of the spraying process is low, and the product performance is good, but the overall appearance is low-grade, which can no longer meet the requirements of some high-end customers. [0004] 2. Electroplating process: At present, the electroplating process is relatively mature. Electroplating is ge...
