采用三辊行星轧制技术生产铜合金管可改变传统的挤压法生产工艺,大幅度提高铜合金管材的生产能力,但对其生产实用性的研究尚处于探索阶段。本文重点以B10白铜合金管坯为研究对象,首先通过有限元模拟对比分析了B10白铜合金管坯与TP2紫铜管坯在三辊行星轧制过程中偏转角和坯料初始温度对成形的影响,并计算出对铜合金管材三辊行星轧制加工中轧辊精整段长度合理控制范围。根据有限元模拟分析结果进行了现场生产实验,成功轧制出铜合金管材获得满意结果。该轧制实验的成功证明有限元模拟的重要参考价值,同时拓宽了三辊行星轧机的应用领域并改善了铜合金管材的生产加工技术。

Comparing with the extruding process technology,the three-roll planetary rolling can increase the production capacity of the copper alloy tube and change the traditional process method.But the practicability of the three-roll planetary rolling for the copper alloy tube is in the researching period.The B10 copper alloy tube was researched as the investigated subject in this paper.The effects of the offset angle and the initial temperature of the copper alloy on the deforming were analyzed by finite element simulation contrasting the B10 copper alloy with TP2 copper tube.The rational length range of the smooth zone of the roller was calculated by simulation in three-roll planetary rolling of copper alloy tube.Based on the simulation results,the experiment was proceeding and the satisfied products were obtained successfully,which proved the important reference value of the finite element simulation.Therefore the applying field of threeroll planetary rolling was extending and the processing technology of copper alloy tube was improved.
