| Abstract: | A discussion was made on the problems of original dies for precision extrusion of plant gear of automobile differential.The extrusion technology was improved,and the new types of blocker die and finish extrusion die were designed.The process experiment shows that with the new technology,the forging deforming force,the cost of material and production can be evidently decreased,while the operating life of the die and the production efficiency is increased. |
