长期以来我国对冲裁毛刺的高度值,以及与其有直接关系的模具合理间隙值等没有规定统一的国家标准,所以在实际生产中常有争议。本文在大量的试验研究和生产实践的基础上,对机裁设备制造行业普遍存在的冲裁毛刺的形成机理和影响毛刺高度值的因素进行了分析,给出关系曲线和经验公式,并订出厂级冲裁毛刺高度值标准。 For a long time our country to punish burr height value, and the mold has a direct relationship between the value of clearance and so there is no uniform national standards, so in the actual production is often controversial. Based on a large number of experimental research and production practice, this paper analyzes the formation mechanism of burr burrs ubiquitous in the cutting equipment manufacturing industry and the factors that affect the height value of burrs. The paper gives the relation curve and empirical formula, Level Burr Burr Height Value Standard.
