Method and apparatus to control the lateral motion of a long metal bar being formed by a mechanical process such as rolling or drawing

Patent Chang, Tzyy-Shuh [Ann Arbor, MI]; Huang, Hsun-Hau [Ann Arbor, MI]; Lin, Chang-Hung [Ypsilanti, MI]

An apparatus to control lateral motion of a bar moving along a guidance path includes a pair of rotatable hubs each having at least first and second rollers at locations around the perimeter of the hub. The first roller has a first retaining groove of a first radius and the second roller has a second groove of a second radius smaller than the first radius. Each hub further includes at least one guiding element located between the rollers with a guide channel extending in the outer surface. A mounting system allows the hubs to be rotated between first and secondmore » « less

Patent Chang, Tzyy-Shuh [Ann Arbor, MI]; Huang, Hsun-Hau [Ann Arbor, MI]; Lin, Chang-Hung [Ann Arbor, MI]

An adjustable guide, includes two or more mechanisms each having a rotatable retaining element containing a retaining groove with a variable radius in its perimeter surface. The grooves form a guidance path to control the lateral, i.e. non-axial, motion of a long bar moving along a longitudinal axis during a production process.The diameter of the guidance path varies according to the variable radii of the grooves. The guidance path increases in size at a predetermined rate, from a point of origin to an end point on the retaining groove. Rotating the retaining elements causes the diameter of the retaining groovesmore » « less
