含能金属铜管轧尖成型方式及参数研究

Research on Tapering Process and Parameters of Energetic Metal-Copper Tubes

摘要: 当前工厂采用滚筒轧尖机实现多次滚压轧尖，轧尖效率低，轧尖成型段一致性差。本文通过对比市面上常见的轧尖方式，并结合索类产品加工安全需求，确定径向锻造缩径成型方式最为满足轧尖需求，并建立了成型工艺参数模型，正向确立了轧尖成型长度和轧尖成型强度之间的关系，通过试验验证，模型的误差在10%以内。新的轧尖成型方式以及成型工艺参数模型，显著的提升了轧尖效率及一致性，降低了劳动强度，缩短了开发周期。

Abstract: Currently, factories employ roller pointing machines for repeated rolling and pointing processes, which suffer from low efficiency and poor consistency in the forming segments. By comparing common pointing methods on the market and considering the safety requirements for cable product processing, this paper identifies radial forging and necking-down as the optimal forming method for pointing. A forming process parameter model is established to define the relationship between pointing length and forming strength through forward analysis. Experimental validation shows that the model’s error margin is within 10%. The new pointing method and process parameter model significantly improve pointing efficiency and consistency, reduce labor intensity, and shorten development cycles.
