COLD FORWARD EXTRUSION WITH ENHANCED REDUCTION RATIO IN SINGLE STAGE

摘要

A cold forward extrusion tool comprising: a die assembly having a die stopper and a die/preform chamber for placing a preform to be extruded, housed in die housing and die assembly; a punch assembly having a punch head and a stopper adapted above the die assembly for extruding a preform; a reciprocating ram connected to the punch assembly enabling to reciprocate the punch assembly to move in vertical direction wherein said stoppers control the vertical movement of the punch assembly thereby controlling the head thickness of extruded component obtained by punching the perform and obtaining higher reduction ratio in single step with the help of die chamber, die housing and die assembly.
