Problems solved by technology

On the one hand, spraying technology enables the product to prevent corrosion, and on the other hand, it is also attractive in appearance. It can be said that the quality of the coating directly affects the user's intuitive experience of the metal frame, thereby affecting the market sales
However, as far as the current domestic spraying technology of metal products is concerned, it is easy to cause phenomena such as uneven thickness and backflow of paint, which seriously affects the quality of painting.

Embodiment Construction

[0010] The invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0011] A metal frame provided by the present invention is formed by punching, and the process includes the following steps: (1) the step of cutting the material by a shearing machine, that is, cutting after positioning on the shearing machine according to the size set by the cutting production instructions; (2) ) the step of punching positioning holes on the material after cutting; (3) then, stretching; (4) after stretching, the step of punching and trimming; (5) punching the material after punching and trimming The steps of single flower and ear-ring flower; (6) flanging the material after the flower is punched; (7) the final step of spraying to form the final metal frame product.

[0012] Among the above processes, the present invention adopts a uniform spraying process different from the traditional technology.

[0013] (1) cleaning. To ...

Abstract

The invention provides a process for uniform spraying of a metal framework. The process includes the following steps that firstly, the surface of the metal framework is cleaned; secondly, the surface of the metal framework is dried; thirdly, at room temperature, protective spraying is conducted through a vacuum spraying machine; fourthly, curing is conducted, wherein baking temperature ranges from 100 DEG C to 160 DEG C, and time ranges from 5 min to 30 min. By the adoption of the process, the thicknesses of sprayed films are uniform, no compressed air exits in paint, no mixture of the paint and the air exists, and the pollution index of the spraying working environment is small.

Description

technical field [0001] The invention relates to the technical field of manufacturing metal products, and more specifically relates to a uniform spraying process for metal frames. Background technique [0002] The metal frame is mainly used to fix the container in a space. The metal frame is made of metal. In addition to the mechanical properties such as its own structure, the quality of the metal frame is also the focus of users' attention on the quality of the exterior coating. On the one hand, spraying technology enables the product to prevent corrosion, and on the other hand, it is also attractive in appearance. It can be said that the quality of the coating directly affects the user's intuitive experience of the metal frame, thereby affecting the market sales. However, as far as the current domestic spraying technology of metal products is concerned, it is easy to cause phenomena such as uneven thickness and backflow of paint, which seriously affects the quality of paint...
