Straightening apparatus includes opposed straightening rollers through which generally cylindrical elongated workpieces pass generally longitudinally. Opposite flat guide members extend between the rollers and have opposed front guide edges between which a workpiece is guided as it travels through the rollers. The side edges of the guide members extending generally perpendicular to the direction of workpiece travel are individually releasably clamped by clamping devices for providing adjustment of the guide members toward and away from a workpiece to facilitate initial adjustment and to renew the front guide edges as they become worn. Each individual clamping device is also independently adjustable in a direction generally perpendicular to the first adjustment direction for imparting curvature to the guide members extending between curved straightening rollers.
Apparatus for straightening elongated cylindrical workpieces comprising:
In a straightening apparatus including opposed straightening rollers through which generally cylindrical workpieces pass generally longitudinally for straightening same, guide means extending between said rollers for guiding workpieces therethrough, each guide means including a guide member having a horizontally extending front guide edge disposed along the movement path of the workpiece horizontally co-extensive with the rollers, each of the guide edges being defined by generally flat sheet stock of plastic material having a degree of hardness that is softer when compared to special hardness steel, releasable clamping devices independently clamping said guide member adjacent each said side edge thereof, said clamping devices being releasable for moving said guide member in one direction toward and away from a workpiece for properly locating said front guide edge with respect to a workpiece during initial adjustment and as said front guide edge becomes worn, and each said clamping device being independently movable in a direction generally perpendicular to said one direction.
