Description
Technical Field
[0001] This utility model relates to the field of QPQ technology, specifically to an oil immersion device for QPQ parts. Background Technology
[0002] QPQ refers to salt bath composite treatment, which includes four steps: nitrocarburizing, oxidation, polishing, and oxidation. After salt bath composite treatment, in order to reduce the surface roughness of the workpiece, the workpiece surface can be polished once, and then oxidized in the salt bath. This is very necessary for precision parts and workpieces with high surface roughness requirements.
[0003] QPQ surface treatment technology is a metal heat treatment process that alters the surface structure and properties of metals through nitriding salt bath quenching and tempering, improving wear resistance, corrosion resistance, and fatigue resistance. It is widely used in the automotive, aerospace, electronics, and medical device industries, offering advantages such as high wear resistance, corrosion resistance, good fatigue resistance, minimal heat treatment deformation, and energy efficiency. During QPQ processing, the treated workpiece needs to be immersed in rust-preventive oil to ensure product quality and prevent rust. However, current immersion techniques often involve directly soaking the workpiece in the rust-preventive oil bath. This leads to the rust-preventive oil adhering to the workpiece surface easily dripping and contaminating the ground when the workpiece is removed. Furthermore, the rust-preventive oil cannot be recycled, resulting in waste. Utility Model Content
