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

Embodiment Construction

[0010] The present invention will be described in more detail below in conjunction with examples. However, the content of the embodiments is only an example and description of the present invention. Those skilled in the art can make various modifications or supplements to the described specific embodiments or replace them in similar ways, as long as they do not deviate from the principles of the invention. Conception or beyond the scope defined in the claims shall belong to the protection scope of the present invention.

[0011] 1. Composition of protective agent

[0012] 12 parts of polyvinyl acetate emulsion, 15 parts of sodium laureth sulfate, 0.5 parts of banana water, 0.5 parts of alcohol ether glycoside, 15 parts of calcium chloride and 47.7 parts of water.

[0013] Two, the preparation method of protective agent is:

Abstract

The invention relates to the technical field of machining, in particular to a protective agent for heat treatment for test tool for welding part machining. The protective agent is prepared by 12 parts of polyvinyl acetate emulsion, 15 parts of laurinol polyether sodium sulfate, 0.5 part of banana oil, 0.5 part of alcohol ether glucoside, 15 parts of calcium chloride and 47.7 parts of water. The protective agent is novel and reasonable in formula design; and in particular, a small amount of alcohol ether glucoside is added, so that the treatment efficiency of the protective agent can be prominently improved. Through matching use of the protective agent, when a detector is heated in a subsequent open fire type normalizing furnace, the surface treatment is more uniform.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to 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 treated uniformly. This...
