How to Accurately Judge the Precision of press mold
The precision of press mold is one of the key factors determining the quality of stamped parts. In order to ensure that the stamping die parts meet the design requirements and production standards, it is crucial to accurately judge the precision of the press mold. The following are some commonly used methods for judging the precision of press mold:
Measurement of die size accuracy: Use precision measurement tools such as vernier calipers, micrometers, etc., to measure the key dimensions of the stamping die. Ensure that the dimensional accuracy of the die meets the design requirements and production standards.
Inspection of die surface quality: Observe whether the surface of the die is flat and smooth, and whether there are scratches, pits, and other defects. The surface quality directly affects the appearance quality and accuracy of the stamped parts.
Detection of die fitting clearance: Inspect the fitting clearance between the upper and lower dies of the stamping die. Excessive fitting clearance can lead to unstable dimensions of the stamped parts, while too small a fitting clearance may accelerate die wear.
Die hardness test: Use a hardness tester to test the hardness of the stamping die. Ensure that the hardness of the die meets the design requirements and production standards to guarantee the wear resistance and service life of the die.
Die trial punching test: Before formal production, conduct a trial punching test on the stamping die. Evaluate the accuracy and performance of the die by observing the size, shape, and surface quality of the trial punched parts.
When judging the precision of press mold, it is also necessary to pay attention to the following points:
Follow relevant standards and specifications, such as national standards, industry standards, etc., to ensure the accuracy and reliability of the judgment results.
Take into account the actual production situation and comprehensively evaluate the precision of the die by considering factors such as the usage environment, material properties, etc.
Regularly maintain and service the stamping die, promptly discover and resolve potential issues, and ensure the stability and reliability of the die's precision and performance.
In summary, accurately judging the precision of press mold is a crucial step in ensuring the quality of stamped parts. By adopting scientific judgment methods and following relevant standards and specifications, the precision and performance of press mold can be effectively improved, providing strong support for the production of high-quality stamped parts."
