Abstract

A fatigue bending and folding test device for an ultra-thin metal strip, including: a first driver module, a first folding module, a first diameter adjustment module, an expansion module, and a frame. The first driver module, the first folding module, the first diameter adjustment module, and the expansion module are all disposed on the frame. The first driver module includes a servo motor, a coupler, and a drive gearbox; the drive gearbox includes a driving gear shaft, a driven gear shaft, a plurality of output end covers, and a plurality of bearings. The first folding module includes an upper folding member, a lower folding member, and a first mounting base. The first clamping member includes a sliding block, a lower clamping plate, an upper clamping plate, a rotating shaft, an intermediate pressure plate, and a plurality of fixing bolts.
