How to inspect the quality of roller processing parts?
Publish Time: 2024-06-17
The quality inspection of roller processing parts is a key link to ensure the performance and service life of rollers. The following are the detailed steps and key points of the quality inspection of roller processing parts:
1. Preparation before inspection
Before conducting the quality inspection of roller processing parts, ensure that the inspection environment is clean and suitable, and prepare the required measuring tools and equipment, such as vernier calipers, micrometers, Shore rubber hardness testers, visual inspection tools, etc.
2. Roller outer diameter deviation inspection
Use tools such as vernier calipers or micrometers to measure the outer diameter of the roller and compare it with the standard size specified by the enterprise to ensure that the roller outer diameter deviation meets the specified requirements.
3. Roller rubber hardness inspection
Use Shore rubber hardness tester to measure 3 points evenly distributed on the roller surface and take the average value. Compare the measured hardness value with the standard hardness specified by the enterprise to ensure that the roller rubber hardness meets the requirements.
4. Roller surface quality inspection
Use visual inspection tools to carefully observe whether there are defects such as bubbles, sand holes, cracks, etc. on the roller surface. The roller surface should feel smooth, non-sticky, and have uniform color. Any surface defects may affect the performance and service life of the roller.
5. Fatigue test inspection
The roller fatigue test is carried out on a special fatigue testing machine. The loading pressure should be at least 800N, and the test running time should be at least 250 hours. After the test, the roller should not have debonding and cracking. This inspection can ensure that the roller has good durability and reliability in actual use.
After completing the above inspections, the inspection results will be recorded and summarized. If there are Roller processing parts that do not meet the requirements, they should be marked and corresponding treatment measures should be taken, such as rework, scrapping, etc. At the same time, the roller processing process is continuously improved and optimized according to the inspection results to improve the quality and performance of Roller processing parts.
