Abstract

PURPOSE:To continuously manufacture the metallic hollow material by the metal extrusion former consisting of shoe and wheel provided with outer circumferential groove, by forming in the shoe a chamber communicating to the outer circumferential groove and the mandrel placed in the midst of this chamber. CONSTITUTION:The shoe 4 is engaged with the wheel in which are engraved two outer circumferential grooves 3, 3', and a longitudinal part of these outer circumferential grooves 3, 3', is covered by this shoe 4 so as to form the path. The shoe 4 has protuberances 5, 5', which are slidably fitted into the outer circumferential grooves 3, 3'. While the wheel 1 is rotated, such raw material as aluminum bar, etc., 7 is fed into the outer circumferential grooves 3, 3', of the wheel 1. Aluminum bar 7 is pressed from upside within the path formed between the outer circumferential groove 3 and the shoe 4, and moves until it strikes the protuberances 5, 5', depending on the friction caused by contact with the bottom and side planes. With further rotation of the wheel 1, the aluminum bar 7 is pushed into the depth; hereby, a high pressure generates at the tip and the aluminum bar 7 flows into the chamber 8 through the communicating paths 9, 9', under a semi-molten state, and two flows join at the chamber 8; then, the semi-molten aluminum is extruded at a hollow condition from the ring type extrusion nozzle 11.
