Abstract
510,628. Producing tubes on push-benches. STEWARTS & LLOYD'S, Ltd., and McLAY, G. S. April 20, 1938, No. 11882. [Class 83 (iv)] In a push-bench method of producing a metal tube a hollow billet or blank with an internally constricted formation at or towards one end is reduced on a mandrel which bears directly or indirectly against the constricted part of the billet. The billet or blank is made hollow in a rotary piercing apparatus and is deformed at a number of points 3 at its end to provide internal shoulders 4 against which a plug 5 with a shouldered portion and a stem 9, adapted to project through the hollow billet 1, is seated. The mandrel 6 then bears against the end of the plug to force the billet, which may have a bevelled end 14, through dies 11 or non-driven rollers. When the tube has been made to the required dimension the stem 9 of the plug may be gripped to pull the tube off the mandrel and the plug subsequently removed by sawing through the thin part of the tube adjacent the shoulder on the plug. The tube may first be loosened on the mandrel by passing it through rollers.
