摘　　要：稳定足够的摩擦驱动力是提高成形质量的关键。为了控制驱动力的大小,保证稳定的出丝过程,分析了摩擦驱动力的影响因素,并通过理论分析推导出摩擦驱动力的计算公式。送丝驱动机构是喷头系统设计的关键,依据分析的驱动力影响规律,设计了一种开放式的远程送丝机构,该机构能够提供足够大的送丝驱动力并且送丝平稳,具有重要的实际参考价值。Stable enough wire driving force is the key to improve the forming quality. Not only to control the size of driving force, but also to ensure the stability of the extrusion filament process, the influencing factors of friction driving force analyzed. And the calculation formula of friction driving force can be derived by theoretical analysis. Wire feeder is the key to design the spray head system. According to the analyzed influence rule of the driving force, a kind of opening remote wire feeder is designed. It can provide large enough friction driving force to ensure wire feeding smooth, and has important practical reference value.
