钢筋矫直切断机的设计
摘要: 论文较为全面、系统地研究了冷轧带肋钢筋的矫直理论及矫直及矫直切断机的基本形式、结构、参数和选型方法,确定了钢筋矫
直切断机的总体设计方案。论文运用材料力学和弹塑性力学的基本原理,将矫直过程中的钢筋看成一个连续弯曲的梁,对冷轧带肋钢筋
的弯曲变形作了详尽的阐述。论文对冷轧带肋钢筋的矫直原理作了进一步的叙述,在此理论的基础上,研究分析了矫直系统参数确定方
法。提出了新的辊系配置方案,并针对此种新的辊型配置方案,计算出了矫直系统力学参数及矫直功率。论文设计了一种较为简单实用
的剪切机构。论文创造性的在矫直切断机上引入了行程开关,实现钢筋的自动定尺切断,提高了自动化程度。
论文在理论分析的基础上,充分联系实际中已有的矫直切断机原理结构,
在降低机器成本的基础上,提高了切断效率,并实现了自动化。

Abstract:This dissertation comprehensively and systematically investgates straightening technology og cold-rolled
ribbed bars,straightening theory of bars,the straightening machines basis type,congigureation,parameter and the method
of choosing bars straightening machine type. Utilizing the basis of material mechanics, elastic-plastic mechanics and
regarding a bar as a continous bending beam in the peocess of straightightening, bend transform of cold ribbed bars is
explained elaborately. Straightening theory of cold-rolled ribbed bars is farther depicted and on the basis of this
theory, confirming method of straightening system parameter is researched. The new roller type configuration theme is
put forward and straightening system mechanical parameter and straightening power of this new theme is calculated. An
simple cutting mechanism is designed.The dissertation draw into the distance-button on the straightening machines, the
bars can be cutting in certain size automly, make it more automly.
The dissertation on the basis of theory analyse, combine with the straightening machines used, on the basis of
lower cost, raise the cutting efficiency, and to be autom.
