差速器行星齿轮新工艺及新型模具设计

摘要

针对汽车差速器行星齿轮原挤压模具结构存在的问题,改进了挤压工艺,设计了新型预成型挤压模和精压模.工艺试验表明:新工艺可显著降低挤压变形力、材料消耗和生产成本,提高模具寿命和生产效率.%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.
