摘要：对销钉机筒挤出机生产过程中的挤出温度、单位体积能耗、胶料粘度及机头压力等工艺参数进行回归分析，得到工艺参数的回归方程。显著性检验表明回归得到的因数和方程是高度显著的。回归分析结果表明，对挤出温度的相关程度由大到小依次为挤出段加热温度、机头段加热温度、螺杆加热温度、塑化段加热温度、螺杆转速和口型大小。回归方程除可用于确定挤出工艺参数外，还可预测单位体积能耗和挤出胶料温度。

Abstract:The parameters such as the extruding temperature,energy consumption per unit volume,viscosity and die pressure for pin barrel extruder during production process were studied.Through the regression analysis of the experimental data,the significance test showed that the regression equations obtained were highly significant.The results indicated that the correlation degree with the extruding temperature gradually decreased in the following order:extruding zone heating temperature,die zone heating temperature,screw heating temperature,plasticizing zone heating temperature,screw rotate speed and die size.The regression equations could be used in guiding the extruding techniques,the forecast of the energy consumption per unit volume and the extruding temperature of compound.

摘要：采用流体力学计算软件Fluent，在对销钉机筒冷喂料挤出机熔融段和计量段的胶料进行三维流动数值模拟的基础上，考察螺杆转速、反向压差、销钉数量、销钉排间距和螺槽深度对挤出量和螺杆转矩的影响。结果表明，螺杆转速是影响挤出机功耗的首要因素，随着转速增大，挤出量增大，功耗和功耗比(螺杆转矩与挤出量之比)下降；反向压差对挤出量、螺杆转矩和功耗比有一定影响，反向压差越大，功耗比越大；每排销钉数量对对功耗比影响不大；销钉排间距对挤出机功耗比有较为明显的影响，若只考虑产量和功耗，则销钉排间距越大越好。

Abstract:On the basis of a 3D flow numerical simulation by Fluent for melt and gauge stage compound of coldfeed pin barrel extruder,the effects of screw’s rotating speed,upward pressure,pin’s count,array pitch of pins and flight channel depth on flow mass and torsion were investigated.The results showed that main influential factor on power consumption was rotating speed of screw.When the speed increased,flow mass increased,power and power consumption(ratio of torsion and flow mass) decreased.As upward pressure increased, power consumption increased.Array pitch of pins had more significant effect.If considering only flow mass and power consumption,greater array pitch of pins was preferred.
