Abstract
Continuous extrusion apparatus (FIG. 1) including a rotatable, grooved, wheel 2 is provided with a shoe 6 mounted on a pivot 7 to be rotatable between a position engaging the wheel 2 and a dis-engaged position. The shoe 6 carries a tooling cartridge 10 including an abutment block 14, an expansion block 16, a die block 18 and an exit block 20 connected together with bolts 22 and held in position by locking keys 46 and a retaining ring 50. A reciprocable ram 60 registers with the cartridge 10 when the shoe 6 is in the dis-engaged position and is operable to raise a cartridge 10 from an associated heating chamber 56 into the shoe 6 or to lower a cartridge 10 from the shoe 6 into a storage chamber (not shown). By utilizing a cartridge 10, change-over and pre-heating of sets of dies is facilitated, enabling the apparatus to be connected directly to a continuous casting furnace (not shown).
