product name：Repeated bending testing machine of electric wire
technical standards： GB/T4909.5-2009 and GB/T238-2002
Use：Mainly used for metal wire comprises a reverse bend test of steel, aluminum, copper, to test the metal wire under plastic deformation and defect properties shown in repeated bending. Equipped with plate clamping device, can also be carried out experiments on bending of plate specimen.
The experimental principle：Should be repeated bending test on the diameter or thickness of metal wire 0.3mm-10mm; detection capability of plastic deformation in bending. Repeated bending test is the sample is fixed, cylindrical bearings around a predetermined radius of curvature of 90 degrees, and then along the repeated bending test in the opposite direction bending.
