Abstract：
|
|
Be aimed at the poor working life of warm extrusion punch in producing cup-shaped parts, the main reasons of the question were analyzed and a new kind of lubrication regime was put forward in this paper. Then the method was analyzed by computer simulation and experiment. Results show: the new lubrication method can reduce extruding force about 30% and the punch temperature some 15%, which can effectively improve the working condition and life of warm extrusion punch.
