Adopt the proving installation that reverses of embodiment 1 described test stratiform composite strip bond strength to reverse band, wherein,
Reverse ribbon dimension: width 1.2mm; Thickness 0.51mm; Fixed length 100mm.
Composite strip material: Ag/CuNi20
Reverse parameter setting: be rotated in the forward 30 circles, reverse rotation 60 circles circulate 1 time.
Tension force is chosen: 800gf.
Reverse speed: 15 circles/minute.
Operation steps is identical with embodiment 1, and the silk material is reversed.If torsional mode is chosen same band 100mm by hand, adopt forward to reverse 30 circles, turn-back 60 circles, and in the actual twist process, reverse by hand and when dextrorotation 21 circles, curled and can't continue, strip breaks during turn-back 12 circles.And after using device silk material of the present invention to be rotated in the forward 30 circles, band is intact, silk material fracture when turn-back the 59th circle.The fracture main cause: reverse inhomogeneously during manual reversing, the subregion exists reverses over-education phenomenon, and apparatus of the present invention band reverses evenly, but parameter is above the fatigue lifetime of band.
