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

[0017] The present invention will be described in more detail below with reference to the embodiments. However, the contents of the embodiments are only examples and descriptions of the present invention, and those skilled in the art can make various modifications or supplements to the specific embodiments described or replace them in similar ways, as long as they do not deviate from the invention. Any idea or beyond the scope defined by the claims shall belong to the protection scope of the present invention.

[0018] The composition of the protective agent

[0019] 12 parts polyvinyl acetate emulsion, 15 parts sodium laureth sulfate, 0.5 parts banana water, 0.5 parts glycol ether glycoside, 15 parts calcium chloride and 47.7 parts water.

[0020] Second, the preparation method of protective agent is:

[0021] First, add 15 parts of sodium laureth sulfate and 20 parts of water to the container, and stir for 5 minutes; then slowly add 0.5 parts of banana water, stir while ad...

Abstract

The invention relates to the technical field of machining, in particular to a heat treatment method of a gauge for welding part machining. The method comprises the steps that grease dirt on the surface of the gauge is wiped off, and then the surface of the gauge is flushed with water for 10 minutes and is wiped and washed by ethyl alcohol for five minutes; a protective agent which is preheated to 45 DEG C is sprayed to the surface of the gauge; the gauge is put into an open fire type normalizing furnace to be heated, and the temperature is 250 DEG C; the heated gauge is transferred into a quenching machine to be quenched; and the gauge is put into a constant temperature furnace to be dried for five hours, and the temperature in the constant temperature furnace is 55 DEG C. The heat treatment method of the gauge is concise in operation process, and the key point is the step that the protective agent is sprayed and then heat treatment is conducted; the formula of the protective agent is reasonably designed, so that the surface of the gauge is protected, and the heat treatment effect and quality of the gauge are improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a heat treatment method of a welding piece processing inspection tool. Background technique [0002] Inspection tool is a simple tool for industrial production enterprises to control various dimensions of products (such as aperture, space size, etc.), improve production efficiency and control quality, and is suitable for mass-produced products, such as auto parts, to replace professional measuring tools , such as smooth plug gauge, thread plug gauge, outer diameter caliper, etc. [0003] Heat treatment is an essential key process in the processing of welding inspection tools. The protective agent used in the heat treatment process mainly has defects such as insufficient protection, so that its surface cannot be uniformly treated when heated in a subsequent open-fire normalizing furnace. This seriously affects the production and processing of the inspection tools, ...
