The present application provides a color register edging method for an aluminum alloy hub. The method is characterized by comprising the following steps: (I) a first pretreatment and drying step, including washing, degreasing, acid pickling and passivation; (II) a body powder and paint spraying and respective curing step; (III) a second pretreatment and drying step, including washing, degreasing, acid pickling and passivation; (IV) an edging color register spraying and curing step, wherein a color register paint is squeezed onto a surface that needs color register by using an injection needle; (V) a third pretreatment and drying step, including washing, degreasing, acid pickling and passivation; and (VI) a high-gloss transparent powder spraying and curing step. The method breaks the conventional shielded protective color register process, the designed grooves can be in a full circle or partial, meanwhile, the size of the grooves can also be changed in the width.

Color register edging method for aluminum alloy hub

Disclosed herein is an aging resistance coating film for a hub, sequentially comprising an aluminum alloy matrix, a silane conversion film, a high-gloss organic resin coating, a periodic variable alloy black chromium coating film and a transparent resin coating. In the coating film, the thickness of the black chromium coating film is increased and the blackness thereof is adjusted according to different content of C. The residual stress of the deposited metal layer is reduced, the problem of cracking during heating and rapid cooling of the coating film is solved, and the binding force between the coating film and the underlying high-gloss resin material is improved. Also disclosed herein is a method for forming an aging resistance coating film for a hub, comprising: (1) silane pretreatment, (2) spraying of high-gloss medium powder, (3) PVD coating, and (4) spraying of transparent powder.

Aging resistance coating film for hub and method for forming protective film

The present invention discloses an on-line wheel cleaning device, having a frame, a cylinder, a motor, a brush chassis, radial brushes, a spline shaft and a spline housing, wherein a sensor enables a wheel to be primarily positioned; a clamping cylinder enables two left clamping rollers and right clamping rollers to clamp the wheel by way of gears, left racks, right racks and a guide rail; a jacking cylinder is used for jacking the brush chassis and the radial brushes through the spline shaft and enabling the brush chassis and the radial brushes to touch a flange plate and a center hole of the wheel, respectively; the motor drives a first belt pulley, the spline housing and the spline shaft to rotate through a synchronous belt and a first belt pulley; an adjusting cylinder jacks up an apex to drive the four radial brushes to move outwards respectively.

On-line wheel cleaning device

This patent discloses an aluminum alloy hub polishing color register process, specifically comprising the following steps of: polishing a blank, pre-treating, spraying transparent powder 1, curing, placing a hard protector, spraying a colored paint, curing, polishing a color register boundary line off line, pre-treating, spraying transparent powder 2, curing and discharging. The process solves the problems that the polished surface is easily scratched in the color register boundary treatment process and that the treatment efficiency is relatively low in the traditional polished color register products, improves the yield and production efficiency of polished color register products and increases the additional values of the products.
