根据滚压包边工艺中板料塑性变形的特点,对平面直边滚压包边过程进行分析,建立了平面直边滚压包边过程的简化解析模型;基于功平衡原理,推导了一个滚压包边过程中包边力的计算公式;计算结果与实际生产接近,且具有上限性质。
Based on the principle of work balance,an analytical model of roll hemming process with straight edge was established,and the formula for calculating roll hemming force of each hemming step was derived.The predicted roll hemming force approach to the results of production experience,and possess upper bound property.
