Dynamic decentering quantitative measuring method, decentering quantitative measuring method, decentering quantitative adjustment manner of the die/di for formation and the punch for formation in the closed-end tube-like object making machine and punch null for measurement

摘要

PURPOSE: To provide a method for measuring the dynamic eccentricity temporally, quickly, and accurately and a method for regulating the eccentricity and a measuring punch employing the method. ;CONSTITUTION: Distance measuring sensors 13, 14, 16, 17 fixed to the body of measuring jig 10 are calibrated by means of a gauge. The body of measuring jig 10 is then fixed to the frame in place of a molding die and aligned with a reference fixing axis. Subsequently, a measuring punch 20 is attached to substituted for the molding punch and the body of measuring jig 10 is passed. Eccentricity of the measuring punch 20 with respect to the axis of the body of measuring jig 10 is then measured based on a plurality of measurement results obtained from the sensors 13, 14, 16, 17.;COPYRIGHT: (C)1995,JPO
