Curved bottom roller mechanism of cold bending rolling backfin

Curved bottom roller mechanism of cold bending rolling backfin

When the operation was bent in the roll -in, in current curved bottom roller mechanism of cold bending rolling backfin, the angle was big more along with bending, and the wheel is high more for the linear velocity of work piece to one side, causes workpiece surface's damage more easily. In orde...

description When the operation was bent in the roll -in, in current curved bottom roller mechanism of cold bending rolling backfin, the angle was big more along with bending, and the wheel is high more for the linear velocity of work piece to one side, causes workpiece surface's damage more easily. In order to solve the problem of not haring workpiece surface in the operation of bending, the utility model provides curved bottom roller mechanism of cold bending rolling backfin which comprises driving shaft, centre wheel, bearing and take turns to one side, the centre wheel is provided with the hollow shaft of driving shaft connecting hole for the center, is provided with the rectangle arch in the one end of hollow shaft, is provided with the step of terminal surface chamfer for alpha at the bellied excircle of rectangle, to one side the wheel be hollow round of the conical surface, its hollow internal diameter and bearing outside diameter phase -match, the oblique angle beta of its conical surface and the chamfer alpha ph
