Abstract

Disclosed is a method for protecting a paint spraying figurative protected zone. According to the method, before a part is sprayed with paint, protection is quickly and accurately carried out on a circular protected zone by using paper adhesive tape and two types of tools, namely two concentric-circle punches made of high-temperature alloy or stainless steel, and a circular punch made of high-temperature alloy or stainless steel; a bottom lamp is arranged at the bottom of a worktable, the surface of the worktable is made of transparent resin or transparent glass, and the bottom lamp irradiates on the part on the surface of the worktable through the worktable. The method includes the following specific technological processes: adhering the paper adhesive tape to rubber or plastic, punching a paper bag by using the concentric-circle punches and the circular punch to remove the rest surface adhesive tape, taking down the punched figurative adhesive tape, adhering the concentric-circle adhesive tape to the surface of the part, aligning small holes by using the bottom lamp, and covering the concentric-circle adhesive tape with the circular adhesive tape. The method for protecting the paint spraying figurative protected zone has the advantages that a protected zone on the periphery of a part hole can be made neat, circular shapes are regular, moving is prevented, and the qualification ratio under one-time acceptance check of products is improved.

Description

technical field [0001] The invention relates to the protection process of spray-painted parts, in particular to a method for protecting a spray-paint pictographic protection area. Background technique [0002] The outer surfaces of many parts of aero-engines need to be painted, but the mounting surfaces and processed surfaces are strictly prohibited from painting and need to be protected. The traditional way is to cut the round tape with scissors and paste it on the small hole. The shape is not accurate and the position is not easy to grasp, which often leads to rework and repair. Contents of the invention [0003] The object of the present invention is to realize the rapid and accurate protection of the peripheral area of ​​the part hole, and especially provides a method for protecting the pictographic protection area of ​​spray paint. [0004] The invention provides a method for protecting a spray paint pictographic protection area, which is characterized in that: the m...
