An intelligent spraying process for the processing and production of metal chairs

Abstract

The invention discloses an intelligent spraying process for the processing and production of metal chairs, which comprises the following steps: step 1, cleaning the metal chair, the cleaning sequence is water washing, degreasing cleaning, pickling and re-washing; step 2, drying and cooling; Step 3: Grinding thermal spraying, using a grinding thermal spraying device to simultaneously polish and thermally spray the surface of the metal chair; Step 4: Control temperature and humidity, control the temperature of the metal chair surface, and control the humidity in the spraying room; Step 5 , the initial spraying of the paint surface, carry out the initial spraying of the paint surface on the surface of the metal chair with a spraying device; step six, measure the thickness of the paint surface, measure the paint surface degree of the surface of the metal chair five with a coating thickness gauge; step seven, Flow-controlled re-spraying, use the spraying device to re-spray the five surfaces of the metal chair. When re-spraying, the PLC controller triggers the flow-controlling device according to the paint surface thickness data to control the flow of the spraying device. The invention is a spraying process which can avoid metal dust pollution and has uniform paint layer thickness after spraying.

Description

technical field [0001] The invention mainly relates to the technical field of metal chair preparation, in particular to an intelligent spraying process for the processing and production of metal chairs. Background technique [0002] The surface of the metal chair needs to be sprayed with paint when it is prepared. The paint can not only protect the metal surface, but also decorate and beautify the metal chair. [0003] According to a metal surface spraying process provided by the patent document with the application number CN201911420600.2, it can be known that the process includes the following steps: degreasing, cleaning and degreasing the surface of the metal surface material; grinding, cleaning the surface of the metal surface material Grinding and polishing; epoxy primer, epoxy primer on the polished metal surface; grinding, surface grinding of the metal surface with epoxy primer; colored topcoat, the polished metal surface There is a colored topcoat on the material, p...
