摘要
针对辊压线生产型钢定长锯切的缺点,进行了研究和探索,提出采用在线剪切方式,分析了剪切原理,得出了剪切力和剪切行程。介绍了据此设计的在线飞剪机的结构和组成,该机实现了型钢的快速无屑在线不停机切断,提高了型钢的断面质量和定长切断精度。经实践证明,原理正确,设计方案合理,结构简单。
This paper is aimed at searching for a new method in customized cut - off cold formed profiles steel on roll -forming line. The slant shear theory is put forward and a new machine is designed. It is explained structure and parts of the machine. This machine can cut off profiles slug less and quickly. It is improved section quality and customized cut - off precision of profiles steel. The machine is proved a correct principle, a reasonable design and simple structure in practice.
