钢筋矫直切断机结构设计（说明书+6张CAD图纸）
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。
钢筋技术推广的社会和经济效益十分显著，因此高强钢筋得到了广泛应用。欧美等工业发达国家对混凝土结构中钢筋的性能要求较高，多采用可焊钢筋，其实物的质量高于标准规定。盘卷供料的钢筋需经矫直切断后才可使用，目前国内满足矫直性能要求的高强钢筋矫直切断机还很少，市场上急需该类产品。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。

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.
Keywords: Cold rolld ribbed bars; Straightening; Distance-button; Cutting
