Description

Technical Field

[0001] The utility model belongs to the technical field of carburizing equipment and relates to an anti-seepage tooling for automobile steering rod parts. Background Art

[0002] Carburizing is a heat treatment method used to improve the hardness, wear resistance and corrosion resistance of metal materials. The process is usually carried out at a temperature of 800℃ to 1000℃, exposing the material to a gas or liquid containing carbon elements, so that carbon atoms penetrate into the surface of the material and combine with it to form a high-hardness carburized layer. In actual production, carburizing increases hardness while also increasing brittleness. Some parts of the parts do not want to be carburized, such as the top hole of the steering rod of the automobile, especially the tapered hole at the top. Therefore, anti-seepage during carburizing is particularly important.

[0003] The conventional treatment method for carburizing anti-seepage is to apply anti-seepage paint. However, due to the shedding of paint or uneven application, it is difficult to achieve 100% anti-seepage of parts. Therefore, it is necessary to develop a new carburizing anti-seepage method to avoid carburization of the anti-seepage part. Utility Model Content
