Abstract:
An entrance roller guide apparatus for shaping a workpiece and guiding the workpiece into a rolling mill, comprising:a guide box frame defining a travel path for the workpiece to travel along downstream from an entrance end and to an exit end;an entry guide extending from said guide box frame at said entrance for horizontally positioning the workpiece at the entrance end of the travel path;left and right side rollers respectively mounted on left and right vertical shafts downstream of said entry guide for horizontally guiding said workpiece along the travel path, said left and right vertical shafts having ends mounted in said guide box frame to be rigidly positioned with respect to each other to support said left and right side rollers to shape said workpiece by compression and thereby reduce a width of said workpiece; andupper and lower rollers respectively mounted on upper and lower horizontal shafts downstream of said left and right side rollers for vertically leveling said workpiece along the travel path, said upper and lower horizontal shafts being mounted in said guide box frame to be rigidly positioned with respect to each other to support said upper and lower rollers to restrict said workpiece from floating during shaping by said right and left side rollers.
