Verfahren zur Härteprüfung von Werkstücken und Vorrichtung zur Durchführung dieses Verfahrens
摘要
The invention concerns a method of testing the hardness of workpieces (22), wherein an impact body (20) is moved onto the workpiece (22) to be tested such that it impinges thereon (along a forward path) and rebounds thereoff (along a return path). On both the return and the forward paths, a movement value of the impact body (20) is detected by a contactlessly operating device and a measure of the hardness of the workpiece (22) is obtained from the difference between the forward and return path movement values. The movement value is detected at at least two points on the forward path and at at least two points on the return path. Corresponding to each movement value detection point on the forward path is a point on the return path at a substantially similar distance from the point of impact.
