电线包覆机头优化设计

Optimization Design of Wire Cladding Head

利用ANSYS软件对电线包覆胶料流场进行分析,研究包覆机头流道结构参数和工艺参数对电线包覆质量的影响,并依据模拟结果对电线包覆机头进行优化设计。结果表明,当电线包覆机头成型段长度为28 mm、模芯外锥角为39°、模套内锥角为45°、芯线牵引速度为0.16 m·s^(-1)时,胶料挤出均匀,电线包覆质量好。

The flow field of the wire cladding compound was analyzed by ANSYS software,and the influence of flow channel structure parameters and process parameters of cladding head on the wire cladding quality was studied.The optimized design of the wire cladding head was carried out according to the simulation results.The results showed that when the forming section length of the wire cladding head was 28 mm,the external cone angle of die core was 39°,the internal cone angle of die sleeve was 45°,and the traction speed of core line was 0.16 m·s^(-1),the extrusion of the compound was uniform,and the wire cladding quality was good.
