Abstract
1372909 Making flexible tubes; extruding; straightening; rolling SCAL SOC DE CONDITIONNEMENT EN ALUMINIUM 23 Nov 1972 [25 Nov 1971] 54176/72 Headings B3P B3A B3E and B3M A frusto-conical flexible metal tube is made by backward extruding a metal blank using a punch 2 provided over at least part of its length with at least one helical ridge 4 whose envelope widens from the head of the punch. The punch has a circular ridge 3 preceding the helical ridge. The backward flow of metal does not contact the punch surface between the ridges. The punch may be formed with a control core (13), Fig. 4 (not shown), and a rotatable outer sleeve (16) provided with the helical ridge. During extrusion the sleeve is rotated at high speed to smooth the formed tube. Alternatively the tube may be smoothed after extrusion by axially movable rollers 10, Fig. 3, whilst it is mounted on a rotatable mandrel 8 for trimming, deburring or threading. The metal may be aluminium or an alloy thereof. The tube is used for pasty materials.
