Abstract
<PICT:0974994/C6-C7/1> <PICT:0974994/C6-C7/2> <PICT:0974994/C6-C7/3> A method of straightening rolled bars characterized in that during the travel of the bars upon a moving cooling bed or like conveyer the bars are subjected to a straightening tension in the direction of their longitudinal axes. Bars fed from a hot rolling mill along a run-out roller bed having driven inclined rollers 2 are successively raised by segmented lifting elements 4, swingably mounted on a shaft 5, on to an inclined apron 7 and subsequently dropped into H-sectioned channels or tube section troughs 10 of a transversely intermittently driven chain type cooling bed conveyer 11. At the ends of each trough gripping tongs 18 connected via draw bars 18a and rollers 20 to adjustable tracks 19 are drawn into or pushed out of wedge shaped gaps between sets of blocks 21 to engage or release the ends of the bars during the traversing motion of the troughs over the cooling bed. The bar ends are rigidly held by the grippers, which may be locked in the closed position whilst being conveyed along the cooling bed. The bars are finally released by the grippers from the underside of the conveyer on to a transversely located roller conveyer 22. Alternatively eccentric gripping means may be used or stationary hydraulic cylinders may be provided which locate the ends of the stock in the troughs by the insertion and withdrawal of keys.
