Topping protection tool and manufacturing method thereof

Abstract

The invention provides a topping protection tool. The topping protection tool comprises a hub and hub window protection plates matched with hub windows of the hub in shape, and the hub window protection plates can be tightly attached to the hub windows of the hub through extrusion. The topping protection tool further comprises a rim protection ring, a center hole protection plug and a spoke protection plate, wherein the rim protection ring is matched with the hub side vertical plate of the hub in shape, the center hole protection plug is matched with a center hole of the hub, the spoke protection plate is matched with spokes of the hub in shape, the rim protection ring can be tightly attached to the rim side vertical plate of the hub through extrusion, the center hole protection plug is inserted into the center hole of the hub, and the spoke protection plate can be tightly attached to spokes of the hub through extrusion. The topping protection tool can meet topping protection requirements of different shapes, and is accurate in topping, easy and convenient to use, capable of being used repeatedly and low in cost.

Description

technical field [0001] The invention relates to a protective frock for color registration and a manufacturing method thereof, in particular to a protective frock for color registration and spraying of wheels, which belongs to the technical field of wheel spraying. Background technique [0002] The requirement for the color registration of the wheel hub is that the border between one color and another color on the same wheel hub is clear, and the colors cannot penetrate each other. In conventional pneumatic spraying (regardless of air gun or electrostatic gun), as long as there is air entering, there will be paint entering, so in general, for color registration spraying, the combination of making templates and masking paper is used to complete color registration. First of all, the cost of templates with adhesive backing is high, and it is difficult to position when pasting, and the pattern will be deformed if the pasting is not allowed. Secondly, use the template to position ...

AI Technical Summary

Problems solved by technology

First of all, the cost of templates with adhesive backing is high, and it is difficult to position when pasting, and the pattern will be deformed if the pasting is not allowed. Secondly, use the template to position and mark the lines, and then use masking paper to extend the marks and paste them. The process is complicated, and it is only easy for flat parts, but for For some grooves, curved surfaces or positions with small internal space, it is difficult to make templates, and it is more inconvenient to draw and paste
