摘要
挤压工艺是一种先进生产工艺,特别适合小模数齿轮的加工。根据齿轮轴的齿形和四方技术要求,确定了齿轮轴挤压工艺方案,设计了齿轮轴一次成形挤压模具。对挤压凹模结构进行优化设计和加工分析,强调了模具使用中注意事项。实践证明,装配冷挤压工艺生产的齿轮轴的全自动洗衣机变速机构与原先产品相比,运动平稳性提高了6.5%、噪音降低了10%、寿命延长了18.5%。
Extrusion process is an advanced production technology, especially suits for the manufacturing process of fine-pitch gear. To meet the demand of the tooth form of gear shaft and quartet technology, the process scheme of gear shaft extrusion was confirmed and once-molded gear shaft extrusion die was designed. Extrusion die structure was better designed and analyzed in terms of manufacturing process, and the precautions for the use of die were emphasized. Practice proves that compared with previous products,the movement stability of the transmission mechanism of the full automatic washing machine equipped with gear shaft produced by cold extrusion process is improved by 6.5%,the noise level is reduced by 10% and the service life is extended by 18.5%.
