Abstract
1,256,945. Rolling tubes. BLAW-KNOX CO. 18 June, 1969 [12 July, 1968], No. 12261/71. Divided out of 1,256,944. Heading B3M. A mandrel which is used in a continuous tube rolling mill includes a head 14 which is secured to a mandrel bar 15 by a quick release coupling. Heads of different diameters can thus readily be interchanged. The coupling incorporates a female member 101 secured to the bar 15, and a male member 102 secured to the head 14. The two members have co-operating external and internal lugs 110 and 107 so that the member 102 can be slid inside the other member and retained by a bayonet action. Clearance between the members is taken up by a spacer 109 having tapered wedge surfaces adjacent the end of the member 102. The angular position of the spacer is adjustable to accommodate different degrees of clearance. A conduit 62 supplies cooling fluid to the interior of the head 14, and is provided with a sleeve coupling 120, 121 which is automatically closed when the head 14 is secured to the bar 15. When the head and bar have been coupled together, a key 115 is used to hold the parts rotationally fixed.
