Profile extrusion method, for ductile material such as solder material or aluminium alloy, uses direct forcing of ductile material bar through forming tool via displaced pressure die

摘要

The extrusion method has a bolt or bar (30) inserted in a recipient bore (16) of a recipient (14) and pushed through a relatively spaced forming tool (38), with a forming cross-section (46), via a pressure die (10) displaced from the opposite end of the recipient. A separation blade is positioned at the end of the recipient facing the forming tool, for removing excess material, a heating device (64) positioned in the axial gap between the recipient and the forming tool for heating the cut surfaces before they are joined together. An Independent claim for a profile extrusion device is also included.
