Abstract
PURPOSE: To make possible the extrusion of the composite rod possessing superior property and adhesive property, by carving into taper the strongly resistive inlet side of the dies opening in order to uniformize the distribution of the material flow in the area of the dies opening, in the extrusion dies for the composite rod.
CONSTITUTION: The inlet side of the dies opening for extruding the composite rod in whose section the steel core 1 is eccentrically located at the lower part of the Al clad material 2, is carved to form the taper 6, and the lower bearing part of the dies opening is transferred to the outlet side, and its length l5 is made shorter than the length l4 of the upper bearing part. By thus preparing the dies opening, the inlet side of the dies, that is the part strongly resistive against the material flow, is freed from the radical drawing rate, so that the flow distribution of the extruded material is uniformized, and the extrusion work for obtaining the sound composite rod with superior surface property and adhesive property is made possible.
