Bending Fatigue Testing Machine 180° for wire specimen according to DIN EN ISO 15630 and ISO 7801

Application:
The facility is used for bending fatigue tests according to DIN EN ISO 15630 and ISO 7801 on wires with diameters of 0.3mm to 10.0mm (max. tensile strength 2.000MPa). Up to 3 samples can be tested at the same time

Functional principle:
The wire samples are bent with a 90° angle to the left and to the right. The lower end of the wire is clamped into a screw terminal and guided through a pair of bending rolls. The rolls ensure bending defined by the wire diameter. The angle deviates by max. +/- 3°. The upper end of the wire is clamped into a movable, motor-driven bending arm. The bending rolls can be exchanged.
The upper end of the wire is clamped into a movable, motor-driven bending arm. The bending arm is driven by a servomotor. The testing facility is adjustable according to the standards indicated before. The detection of specimen breakage is based on the electrical conductivity.
