What kind of instrument can be selected for testing the hardness of materials used in automobile stamping parts?

There are many ways to test the performance of the material used for a stamping part. For its hardness testing, more Rockwell hardness testers are used. It can accurately measure the accuracy of stamping parts and judge whether it is qualified or not. Is this measuring instrument really so easy to use?Since there is no standard for the shape of automobile stamping parts, it is difficult to measure its performance, especially for those small and complex shape stamping parts, which cannot be measured by ordinary equipment. At this time, the portable surface Rockwell hardness tester provides many aspects, and it is just suitable for this type of stamping parts. The hardness levels of the materials used to make different stamping parts are also different, so there are different hardness testers that can be used. For example, the aluminum alloy plate can be tested with a Webster hardness tester. When the material thickness is greater than a certain degree, the Barcol hardness tester can be used instead. , in order to achieve a more accurate measurement effect. In the process of stamping and forming, the temperature of the workpiece will change. If it is not controlled by the action of lubricating oil, not only the quality of the stamping parts will be affected, but even the stamping die may be damaged. It is different if lubricating oil is added, so that it can form a protective film on the surface of stamping parts, avoiding the adverse consequences of temperature production. Especially for cold forging stamping, lubricating oil is one of the indispensable fabrication aids. Of course, we must pay attention to the amount of lubricating oil, avoid waste and ensure the cleanliness of the environment on the premise of maintaining efficacy.
