AI Technical Summary
The mandrels on existing cold rolling mills are prone to swaying and jamming during transmission, affecting stability. In particular, thinner mandrels are prone to bending and sagging on the roller assembly, resulting in uneven transmission.
An adjustment assembly is set between the roller clamping mechanism and the mandrel, including a movable rod, an electric telescopic rod, a limit ring, and a bidirectional screw. The spacing between the mandrels is adjusted by the electric telescopic rod, and the spacing between the limit rings is adjusted by the bidirectional screw, so as to achieve stable positioning of the mandrel.
