摘　　要：介绍了小伞齿锻造的2种成形工艺,通过设计胎模达到工艺改进的目的,使原材料的消耗量从251.8kg降低到99.5kg,材料的利用率从25.5%提高到64.4%,机加工时减少了一半。结果表明,在小批量生产时,为达到或接近模锻件的质量,采用胎模锻,是一种经济、可靠、理想的方法。Two kinds of forging processes for the small bevel gear are introduced in this paper.The pre-forming step is designed to improve the forging process.The consumption of raw materials is reduced from 251.8Kg to 99.5Kg,and the material utilization rate is increased from 25.5%to 64.4%.Meanwhile,the machining time has reduced by half.Practice has proved that the pre-forming process is an economic,reliable and appropriate method in small batch production.
