滚切式双边剪剪刃间隙精度控制的探讨

双边剪剪刃间隙精度是影响双边剪切边质量的主要原因之一,剪刃间隙精度主要是指剪刃间隙设定值和剪刃间隙平行度偏差值。介绍了剪刃间隙调整机构工作原理和调整曲线,对退刀机构进行分析,探讨剪刃间隙和钢板厚度、强度之间的关系,研究生产中出现的剪刃间隙调整范围不够和平行度精度超差等问题,提出了解决措施。

Discussion on Knife Gap Accuracy Control of Double- Side Trimming Shear

The knife gap accuracy of double-side trimming shear is one of the key factors influencing the cutting quality.The knife gap accuracy refers to the difference between the knife gap setting value and knife gap parallelism.The paper describes the working principle of the knife gap adjustment mechanism and the regulation curve,analyzes the knife retraction device,discusses the relationship between knife gap and plate thickness/strength,investigates the problems such as insufficient knife gap adjustment range and poor parallelism accuracy as well as the countermeasures during production.
