NUMERICAL SIMULATION OF TOOL WEARING IN REVERSE COLD EXTRUSION PROCESSES

Petru Paul DINCU, Gheorghe ACHIMAȘ, Adriana NEAG

Abstract


Numerical simulation of the wearing processes allows the optimization of the shape and properties of extrusion tools before their manufacturing. As a result the costs for redesigning caused by the die incomplete filling, material overlapping and unacceptable wear of the tools can be avoided. The wear of the punch and extrusion die should be assessed both through the specific wear, this means the wear that corresponds to 1000 extruded parts and the parameters of the wearing region.

Key words: reverse extrusion, tool wearing, extrusion dies, heat distribution in reverse extrusion.
