Lettering and paint embedding method for thin plate disc-shaped duralumin bottom plate part

Abstract

The invention relates to a lettering and paint embedding method for a thin plate disc-shaped duralumin bottom plate part. The bottom plate part comprises an annular edge plate and a circular truncated cone, and an open bottom hole is formed in the bottom face of the annular edge plate; a plurality of lettering areas are arranged on the plane of the bottom hole; and line carving is performed on the bottom surface of the annular edge plate. The lettering and paint embedding method comprises the following steps that: S1, lettering and line carving are conducted, specifically, the bottom plate part is clamped, lettering contents of different lettering areas are edited, and lettering is conducted on the lettering areas through lettering equipment, line carving is performed on the bottom surface of the annular edge plate, the depth of the lettering and line carving is 0.2-0.3 mm, and the width of the lettering and line carving is 0.3 mm; S2, inspection is performed, specifically, a laser lettering font inspection template is adopted to compare and inspect lettering fonts, and a vernier caliper is adopted to inspect the depth and width of the lettering and line carving; S3, paint embedding is conducted, specifically, a part to be subjected to paint embedding is wiped with aviation gasoline, paint embedding is carried out by adopting C04-42 black alkyd enamel paint, after paint embedding, the part is naturally aired, after being aired, the paint at a non-paint-embedded part is cleaned, and the part is placed in a constant-temperature drying oven to be dried.

Description

technical field [0001] The invention relates to the technical field of lettering and lacquer embedding of thin plate parts, in particular to a method for lettering and lacquer embedding of a disc-shaped duralumin bottom plate part of a thin plate. Background technique [0002] In the field of aerospace product parts, duralumin material is a commonly used raw material for parts manufacturing. Due to the material characteristics of duralumin itself, it will be deformed to varying degrees during machining, which will affect the overall quality of parts, especially thin plate disks. Shaped duralumin parts. Such as figure 1 Shown is a thin-plate disc-shaped duralumin base plate part, the base plate part material is duralumin, the grade is 2A12, and it is a thin-plate disc-shaped structure with a diameter of After processing, the thickness of the stepped circular platform in the middle is 3mm, the wall thickness of the annular edge plate at the edge of the circular platform is ...

AI Technical Summary

Problems solved by technology

Since the bottom plate part is an easily deformable part structure, if the lettering and the depth of the engraving line are too deep, firstly, the deep lettering and the large number of lettering areas will easily cause deformation of the part, which will affect the flatness of the part; cause blurred writing

If the lettering is shallow, it is prone to defects such as paint not embedded, uneven paint, easy to fall off, etc., which will affect the appearance

In addition, with the existing paint embedding process and paint solution, it is easy to fall off after embedding paint, and repeated paint repairing operations are required, and the efficiency of embedding paint is low
