Abstract
A sizing press has a pair of opposed rotatably supported pressing tools for reducing the width of a flat metal slab. Piston cylinder assemblies rotatably oscillate the pressing tools relative to each other. Each pressing tool has first and second slab-contacting surfaces which extend in different planes. The invented method of this invention includes the steps of moving the pressing tools toward each other against the sides of a metal workpiece and reducing the width of an initial workpiece length. Thereafter, rotating the pressing tools to further reduce the width of only a portion of the initial workpiece length and to reduce the width of an adjacent workpiece length.
Claims20
A sizing press for reducing a width dimension of a metal workpiece, said sizing press comprising:
- a. a pair of generally axially opposed pressing tools rotatably supported on said sizing press, each pressing tool including a first workpiece-contacting surface and an adjacent second workpiece-containing surface, said first surface and said second surface extending outwardly and rearwardly thereby positioning said first surface and said second surface in different planes;
- b. an oscillating means supported on said sizing press and operatively connected with at least one of said pair of pressing tools for oscillating said opposed pressing tools toward and away from one another, said oscillating means includes at least two force transmitting piston cylinder assemblies, one of said two force transmitting piston cylinder assemblies engaging said pressing tools behind said first surface adjacent a first end thereof and a second of said two force transmitting piston cylinder assemblies engaging said pressing tool behind said second surface adjacent a second end thereof;
- and
- c. at least one feed means positioned on said sizing press for successively feeding such workpiece between said pair of pressing tools during operation of said sizing press.
A sizing press, according to claim 7, wherein said sizing press further includes a process control system.
