摘要:

针对楔横轧工艺,研究轧辊成形角变化对空心件收口成形的影响规律。根据工件成形尺寸,使用UG软件建立4种模具方案,每个方案中模具的不同之处在于成形角的变化方式不相同。运用Deform软件模拟空心件的楔横轧成形过程,对比模拟结果,得出最佳的成形工艺方案,并分析了最佳方案下的等效应力和等效应变的变化。试验结果表明,采用最佳模具成形方案轧制出的工件可以达到尺寸要求。最佳成形工艺方案为:在轧制过程中,工件转过6.5圈,前5圈为变形,成形角值从0°连续线性增加到3.6°,第6圈为成形过程,成形角为3.6°;保持成形角不变,第6.5圈为卸载阶段。
 

Cross wedge rolling was used to study the effect of the change of rolling forming angle on the hollow-ware heals. According to the forming dimensions of workpiece,four models were established by UG software, and the difference of die among four models was the change of forming angle. Deform software was used to simulate forming process of cross wedge rolling of hollow-ware heals. Compared with simulation results,the best forming program was acquired and the changes of effective stress and effective strain for the best forming program were analyzed. The experimental results show that the rolled workpiece can reach the requirements of dimension by using the model of the best forming program. The best forming program is that in rolling process,the workpiece is turned 6.5 circles, and it is deformed in the former 5 circles, and the forming angle increases linearly from 0°; hollow-ware heals to 3.6°. The sixth circle is forming stage and the forming angle is 3.6° constantly,and the 6.5 circle is unloading stage.
