As we all know, if we want to ensure the quality of products, inspection is essential. As a part of automobiles and motorcycles, the quality of piston rings cannot be ignored, and the effective way to ensure quality is to conduct quality inspection on production. Today, the editor will tell you what aspects of piston rings need to be inspected.
As an important part of the automobile, piston rings have a very harsh working environment and require high hardness, wear resistance and service life. Therefore, many manufacturers use medium frequency induction heating equipment for quenching heat treatment to meet their working requirements.
According to the technical requirements and working conditions of the piston ring, we need to inspect the following aspects:
1. No cracks, burrs, rust, chips, etc. are allowed on the surface.
2. The outer circumferential surface of the piston ring and the upper and lower end surfaces of the piston ring are free of knife marks, scratches, cracks and oxide scale after rough machining. The demagnetization should be complete, otherwise the piston ring will be abnormally damaged.
3. Inspection of hardness.
4. The surface of the piston ring after chromium plating is free of chromium tumors, chromium layer cracks, sharp chrome edges and chipping.
5. The chromium layer and the piston ring should be firmly combined without falling off.
The editor briefly talked about the quality inspection of piston rings, hoping it will be helpful to your work. If you have a better way to ensure the heat treatment quality of piston rings, please leave us a message for feedback. Your support is the driving force for our progress.
