Abstract

PURPOSE: To easily perform extrusion in prescribed dimension and shape, by installing a straightening block at the outlet side section in the die in such a way that the block rocks in accordance with meandering movement of shaped materials, when the shape of extrusion forming material, of an Al alloy is straightened.
CONSTITUTION: When a shaped material M suck as sash is formed by an extrusion of an Al alloy material with a die 1 composed of a baffleplate 2, a die 3, and a back die 4, a pocket 8 connected to an open hole 7, through which the shaped material M passes, is formed at the rear end of the back die 4, and a straightening block 9 is loosely inserted into the hole 7. Moreover, a bolt having a hexagonal socket head 11 is fixed to the end of a wire bar 10 passing through the straightening block 9, and the straightening block 9 is supported in such a way that the block rocks in radial directions. While material M makes meandering movements after coming out from the die 1 depending on the shape and the extrusion condition, almost all the shaped materials coming out from the die are finished within a range of tolerance without any requirement for correction, because the straightening block 9 also rocks in accordance with the meandering movement of shaped material M.
