Abstract
A method for material testing of an elongated work piece drawn through a drawing die arrangement, wherein the drawing die arrangement includes a drawing tool that acts on the elongated work piece, forming it in a forming region, carries out the material testing in the forming region.
Claims6
A material testing method for material testing of a solid rod comprising:
- (a) providing a drawing die arrangement having a drawing tool support that carries a drawing tool and counteracts the drawing tool and a mass distribution measurement device;
- (b) drawing the solid rod through the drawing die arrangement to cause the drawing tool to act on and shape the solid rod in a forming region of the drawing die arrangement;
- (c) sending a measurement signal from the measurement device of the drawing die arrangement through the solid rod in the forming region of the drawing die arrangement;
- (d) receiving the measurement signal;
- (e) measuring via the measurement device an attenuation of signal strength of the measurement signal after the measurement signal passes through the solid rod;
- and
- (f) evaluating via the measurement device the attenuation such that local defects in the solid rod are identified.

A drawing die system comprising:
- (a) a solid rod;
- and
- (b) a drawing die arrangement comprising:
- (i) a drawing tool adapted to act on the solid rod and shape the solid rod in a forming region of the drawing die arrangement as the solid rod is drawn through the drawing die arrangement;
- (ii) a drawing tool support carrying the drawing tool and counteracting the drawing tool;
- and
- (iii) a measurement device acting to measure in the forming region of the drawing die arrangement, the measurement device comprising an attenuation determination device configured to transmit a measurement signal, to receive the measurement signal, to measure an attenuation of signal strength of the measurement signal after the measurement signal passes through the solid rod, and to evaluate the attenuation such that local defects in the solid rod are identified.
