摘　　要：锥形双螺杆是锥形双螺杆挤出机的核心部件,其加工精度直接影响螺杆副的啮合以及挤出机出性能。在分析了现有的锥形双螺杆的加工方法基础上,提出了一种在数控铣床上加工锥形螺杆的方法,通过对锥形双螺杆几何外形以及啮合特性的分析,利用自动编程系统生成的数控程序,加工出直廓齿形的锥形螺杆。该研究成果可提高锥形螺杆的生产效率,具有广泛的义工程意义。Conical twin-screw is the key part of conical twin-screw extruder, and the machining precision of that directly affects the meshing of conical twin-screw and extruder＇ s performance. This paper researches the state of the art of machining conical twin-screw and proposes a new method to machine conical twin-screw on NC milling machine, which machines conical twin-screw with vertical tooth form based on the analysis of conical twin-screw geometric contour and meshing characters and through NC program generated by an automatic programming system. The research result advances the production efficiency of conical twin-screw and has a broad engineering significance.
