建立了双面犁法加工整体翅片管的成形数学模型 ,推导了翅片结构参数与加工用量及刀具几何参数之间的关系 ,为优选翅片结构参数以达到最佳传热效果提供了理论依据。理论分析和试验结果均表明 ,对于某一刀具 ,翅片高度和平均翅厚均随挤压深度和进给量的增加而增大
The forming mathematical model of integral finned tube by double-sided plow method was established. The relationship between the structural parameters of the fin and the processing parameters and geometric parameters of the tool was deduced, which provided the theory for optimizing the structural parameters of the fin in order to achieve the best heat transfer effect in accordance with. Theoretical analysis and experimental results show that for a certain tool, the fin height and average fin thickness increase with the increase of extrusion depth and feed rate
