Embodiment 1

[0032] A method for coating cylindrical parts, comprising:

[0033] 1), the improved settings for the structure of the cylinder parts:

[0034] The structure of the column body includes a column head and a column rod, and multiple facets are arranged between the adjacent sides on the column head to avoid grooving on the adjacent sides. Specifically:

[0035] The to-be-sprayed surface of the column part includes the end-to-end stigma to be sprayed and the pole to be sprayed, the stigma to be sprayed has a stigma to be sprayed side, and the stigma to be sprayed in the length direction. The first spray surface, the second spray Surface, the third spraying surface and the fourth spraying surface, the first spraying surface and the third spraying surface are arranged oppositely, the second spraying surface and the fourth spraying surface are oppositely arranged, and there is a first spraying surface between the first spraying surface and the second spraying surface. facets, the fi...

Abstract

The invention discloses a method for coating cylindrical parts, comprising: 1), an improved setting for the structure of the cylindrical parts: the structure of the cylindrical parts includes a column head and a column rod, and a plurality of edges are arranged between adjacent sides on the column head 2), carry out surface pretreatment on the surface to be sprayed of the part; 3), spray the surface to be sprayed on the pole; 4), apply the first prismatic surface, the first Spray the second, third and fourth facets; 5) spray the first spray surface, the second spray surface, the third spray surface and the fourth spray surface. The invention adopts the method of arranging slender edge surfaces between two adjacent surfaces, so that the edge transition between the original two larger surfaces is smoother, the edge warping phenomenon during spraying can be effectively reduced, and simultaneous grooving on both sides is avoided. the cost of repeated processing.

Description

technical field [0001] The invention relates to the field of coating of cylindrical parts, in particular to a coating method of cylindrical parts. Background technique [0002] Spraying is a coating method that is dispersed into uniform and fine droplets by means of pressure or centrifugal force through a spray gun or disc atomizer and applied to the surface of the object to be coated. It can be divided into air spraying, airless spraying, electrostatic spraying and various derivatives of the above-mentioned basic spraying forms, such as high-flow and low-pressure atomizing spraying, thermal spraying, automatic spraying, multi-group spraying, etc. [0003] In the existing spraying, in order to prevent the edge of the coating from lifting, grooves can be made on the edge of the workpiece before spraying. However, not all workpieces are suitable for grooving due to pre- or post-grooving costs. It is therefore necessary to provide a coating method that is not suitable for gro...
