Problems solved by technology

The production efficiency of manual spraying is very low, and the product quality is unstable, which is greatly affected by the operator's own skills
In addition, due to the high labor intensity of the operator and the direct contact with the paint, the harm of the paint to the human body is increased, and the working environment is also polluted.

Abstract

The invention relates to a coating method of titanium alloy forged piece surface glass protective lubricant, which belongs to a surface treatment technology and relates to the improvement of the coating method of titanium alloy forged piece surface glass protective lubricant. Water-based glass protective lubricant is coated on the titanium alloy forged piece surface before the titanium alloy forged piece is forged and molded. The coating method is characterized in that the titanium alloy forged piece is placed on an electrostatic spraying production line for electrostatic spraying. The coating method greatly improves the production efficiency and the product quality stability, reduces the labor intensity of operators, reduces the harms of coating to human bodies, and improves the working environment.

Description

technical field [0001] The invention belongs to the surface treatment technology, and relates to the improvement of the coating method of glass protection lubricant on the surface of titanium alloy forgings. Background technique [0002] Titanium alloy forgings need to be coated with glass protective lubricant on the surface before forging. The glass protective lubricant can prevent oxidation during the heating and forging process of the forging, and can reduce the frictional resistance between the forging and the mold during the forging process. Play the role of lubrication. Glass protection lubricant mainly contains SiO 2 、Al 2 o 3 , B 2 o 3 and other components, water is generally used as a diluent. At present, manual methods are used to spray protective lubricants. First, the forgings must be preheated to ensure that the paint does not flow during spraying. Need to dry. The production efficiency of manual spraying is very low, and the product quality is unstable,...
