Abstract

Apparatus for rolling tubular blanks utilises fluid between the internal surface of a blank 17 and a mandrel 13. The apparatus in our form comprises a hydraulic cylinder 3 within a hollow spindle and rotatable therewith, the cylinder containing a piston 4 and one end of the mandrel. Duct means 14, 15 supply hydraulic pressure to the outside of the mandrel on which the blank is located. Locking means 18, 19 hold the blank on the mandrel against rotation and roller means 22 having associated heater means 21 act on the surface of the blank to effect the hydroplastic reduction thereof while fluid is located in a deformation space 16 between the blank and the mandrel. The rollers 22 are controlled by a template (38). In a modification, pressure pulses are produced by plungers (51) urged into the rotating cylinder by stationary cams (52). <IMAGE>
