Sheet metal bending machine - has liftable pressure roller driven by two gear wheels rotating on fixed axle

摘要

The bending machine for tough materials enables automatic operation and consists of a main roller, with a pressure roller positioned underneath. The pressure roller is fitted for sliding under the effect of a spring assembly. The roller is driven by two gear wheels mounted on both ends of the roller and rotating around a fixed axle. - The machine has an arm on an axle for pivoting with one end resting on a support which allows lifting. The machine has a bending roller with a fixed axial spacing but allowing swinging motion in relation to the main roller. The pressure between the meshing teeth of the gear wheels is directed sto that with increasing feed resistance on the sheet, the pressure in direction of the main roller increases.
