Abstract

28,867. Derain, L. G., and Mallison, G. May 27. Squirting.-In extrusion presses for tubular articles of any section, the mandrel has a head, which is connected to the plunger so that a shoulder occupying the full area of the clearance between the mandrel and cylinder always acts on the rear of the ingot, and thus prevents metal from penetrating between the mandrel and the plunger, but allows the plunger to be withdrawn separately in case the mandrel jams in the tube. As shown in Fig. 1, the head b of the mandrel a is held by friction in a socket in a detachable piece d, which is connected to the plunger e by a right and left handed screw f. The head may be of the same diameter as the cylinder and may be socketed at its rear side to fit a correspondingly shaped detachable piece. The socket may be cylindrical, conical or cylindro-conical. For forming thick tubes the mandrel may be tubular.
