ABSTRACT:
A combined support and guide for the mandrel of a continuous rolling mill comprises a support structure carrying three levers pivotally mounted on respective pins supported parallel to, equidistant from and equiangularly spaced around the horizontal rolling axis of the mill, each lever carrying a respective roller, freely rotatable thereon about an axis which intersects the lever pivot axis, the roller axes lying in a common vertical plane. One of the levers is connected to the other levers by respective pivotally attached link arms forming parallelogram linkages, such that angular displacements of the one lever under the action of drive means causes simultaneous, similar displacement of the other levers to displace the rollers equally towards the rolling axis to accommodate and support a mandrel between them in coaxial alignment with the rolling axis, the rollers guiding axial movement of the mandrel, there being an adjustable stop which, after separation of the rollers to allow passage therebetween of a forging carried on the mandrel, allows automatic repositioning of the rollers to support the mandrel once again.
