在建立圆截面轧扁的物理模型基础上,确定了定长轧制工艺制件长度与轧辊直径之间的数学关系模型,以JD型整体放电极线定长轧制成形为算例,求解定长轧制时的轧辊直径,分析圆截面轧扁时影响制件长度的因素,提出了轧制过程的调整和控制方法。在实际轧制试验情况下,制件的长度误差为1.16%,满足工艺质量要求,取得了较好的应用效果。 Based on the establishment of the physical model of circular cross-section flattening, the mathematical relation model between the length of workpiece and the diameter of the roll was established. Taking JD type integral discharge polar line fixed-length rolling forming as an example, The roll diameter during long rolling, the factors that affect the length of the part when the circular section is flattened, and the adjustment and control method of the rolling process are proposed. In the actual rolling test case, the length of the workpiece error of 1.16%, to meet the quality requirements of the process, and achieved good results.
