摘要
采用应力分析的方法建立了矩形管双道次无芯棒四辊辊挤成型过程挤压力的计算公式,并通过实验对所建立的理论公式进行了验证,证明该公式具有较高的精度,可以用于相似工艺的计算和设备设计。
Based on the stress analysis, a formula was established, which can be used to calculate the extrusion force of shaped tube in double passes roll-type extrusion process. The formula was verified by experiments. It will have applications in the similar process and equipment design.
