Preparation method of protective agent for heat treatment of gauge for welding part machining

Abstract

The invention relates to the technical field of machining, in particular to a preparation method of a protective agent for heat treatment of a gauge for welding part machining. The preparation method comprises the steps that firstly, 15 parts of sodium laureth sulfate and 20 parts of water are added into a container, and stirring is conducted for five minutes; secondly, 0.5 part of banana oil is added slowly, stirring is conducted while the banana oil is added, and stirring is conducted for five minutes after adding is completed; thirdly, 12 parts of polyvinyl acetate emulsion and 10 parts of water are added slowly, stirring is conducted while the polyvinyl acetate emulsion and the water are added, and stirring is conducted for five minutes after adding is completed; fourthly, 0.5 part of alkyl ethoxy polyglycosides is added slowly, stirring is conducted while the alkyl ethoxy polyglycosides is added, and stirring is conducted for five minutes after adding is completed; and finally, 15 parts of calcium chloride and 17.7 parts of water are added slowly, and stirring is conducted for 15 minutes. By the adoption of the step-by-step adding method, the solubility of all the substances can be improved, the probability of particle aggregation can be avoided, and the surface protection function of the protective agent is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a preparation method of a protective agent used for heat treatment of a inspection tool for welding parts processing. Background technique [0002] Inspection tools are simple tools used by industrial production enterprises to control various dimensions of products (such as aperture, space dimensions, etc.), improve production efficiency and control quality, and are suitable for mass-produced products, such as auto parts, to replace professional measuring tools , such as smooth plug gauges, threaded plug gauges, outer diameter snap gauges, etc. [0003] Heat treatment is an essential key process in the processing of inspection tools for welding parts. The protective agent used in the heat treatment process mainly has the defects that it cannot be completely protected, so that when it is heated in the subsequent open flame normalizing furnace, its surface cannot be ...

AI Technical Summary

Problems solved by technology

The protective agent used in the heat treatment process mainly has the defects that it cannot be completely protected, so that when it is heated in the subsequent open flame normalizing furnace, its surface cannot be treated evenly.

This has seriously affected the production and processing of the inspection tool, and severe cases may lead to the complete scrapping of the inspection tool
