Aluminum alloy car logo processing method

Abstract

The application provides an aluminum alloy car logo processing method, comprising the following steps: S1: die casting forming: using a die casting mold to die cast a product; S2: CNC processing: taking out the die cast product, and removing a head and a slag ladle through CNC processing; S3: surface wire drawing treatment: performing wire drawing treatment on the surface of the product after removing the head and the slag ladle; and S4: PVD processing: performing PVD coating processing on the product after the surface wire drawing treatment. The aluminum alloy car logo processing method has the beneficial effects that, compared with directly performing CNC processing on an aluminum plate to obtain a car logo, the aluminum alloy car logo processing method saves working hours and cost by performing die casting on a product and then removing a head and a slag ladle through CNC processing, and then performing surface wire drawing and PVD coating on the car logo can make the surface of the product smooth, prolong the service life of the product, and improve the texture of the product.

Description

[Technical Field]

[0001] This invention relates to the field of aluminum alloy processing technology, and in particular to a method for processing aluminum alloy car logos. [Background Technology]

[0002] Aluminum alloys, with aluminum as the main raw material and a small amount of other metallic elements, are lightweight, high-strength, and corrosion-resistant, and are widely used in production and daily life. Car logos made of aluminum alloys are lightweight, high-strength, and have good tensile and compressive strength and corrosion resistance. The traditional processing method for aluminum alloy car logos is to directly CNC machine the shape of the car logo from the aluminum alloy sheet, and then draw, anodize, and electrophoretically apply the process to give the logo a bright texture. However, this processing method is inefficient and costly.

[0003] In view of this, the present invention provides a method for processing aluminum alloy car logos to solve the above problems. [Summary of the Invention]

[0004] The technical problem this invention aims to solve is the low efficiency and high cost of current methods that involve directly machining aluminum alloy sheets into the shape of car logos using CNC machining, followed by wire drawing, anodizing, and electrophoresis to achieve a glossy finish. This invention provides an aluminum alloy car logo processing method to address these issues.

[0005] The solution to the technical problem of this invention is: a method for processing aluminum alloy car logos, comprising the following steps:

[0006] S1: Die casting: Products are formed by die casting using die casting molds;

[0007] S2: CNC machining: Remove the die-cast product and remove the slag and slag bag through CNC machining;

[0008] S3: Surface drawing treatment: The surface of the product after removing the slag head and slag bag is drawn;

[0009] S4: PVD processing: The product with a brushed surface is subjected to PVD (physical vapor deposition) coating processing.

[0010] Preferably, in step S3, the product with the slag and slag removed is placed into a wire drawing machine, and the surface of the product is drawn using 320 mesh steel wire.

[0011] Preferably, in step S4, the PVD coating process includes cleaning, vacuuming, target washing and ion cleaning of the product after surface wire drawing, coating, cooling and unloading, and post-treatment.

[0012] The beneficial effects of this invention are that the aluminum alloy car logo processing method of this invention saves time and cost compared to directly CNC machining the aluminum plate to form the car logo by die casting the product and then performing CNC machining to remove the slag and slag. Afterwards, the car logo is surface brushed and PVD coated to make the surface of the product smooth, extend the service life and texture of the product. [Attached Image Description]
