Abstract: An electro-plastic shape control roller system based on transverse partitioning and independent control is provided. The electro-plastic shape control roller system includes a shape control roller mandrel, conductive copper rings, insulating ceramic rings, a shock-absorbing rubber sleeve, an insulating ceramic roller sleeve, and conductive rotary joints, etc. This system constructs a transversely partitioned electro-plastic shape control roller by alternately arranging the conductive copper rings and the insulating ceramic rings. During operation, a strip is wrapped at a certain angle above the electro-plastic shape control roller to ensure a tight contact between the strip and the conductive copper rings. According to the principle of minimum resistance in the conductive copper ring-strip-adjacent conductive copper ring pattern, the electro-plastic shape control roller system controls the on/off of each set of independent conductive copper rings through the external control circuit.

Abstract: A hydraulically controlled backing roller includes a mandrel, two cover plates which are installed at two ends of the mandrel through screws respectively, and two screwdown gears which are installed at two end portions of the mandrel respectively. The two screwdown gears are engaged with an output rack of a screwdown hydraulic cylinder, multiple saddle ring sets are sleeved on the mandrel at equal intervals, a saddle ring of each of the saddle ring sets is fixed with a frame through a fan-shaped plate, a backing bearing is provided between two adjacent saddle ring sets; an inner eccentric ring of the each of the saddle ring sets is driven to rotate by hydraulic driving, so that the mandrel has a deflection deformation, and the deflection deformation is transmitted to other adjacent rollers through the backing bearing.
