摘要:在当今现代化发展的大趋势下，钢铁行业已经成为了各个国家经济发展力量的中流砥柱，产业技术含金量俞高，其生产效率俞高，对应带来得经济效益也成倍增长。在当代钢铁冶炼行业的大步发展中，各国进行得最为强力得技术开发的重心落在了处理钢材的效率上。因为钢材产业冶炼过程中，板材处理的工艺之复杂，数量之庞大，一步不起眼的提高板材处理效率的工艺带来的价值是不能想象的，所以对于该课题研究的意义也非常重要。

圆盘剪切机在工厂加工的前端作业线，一般设置精整加工线，其作用是将向前行进的钢铁板材纵向切齐或者剪切成窄型带钢。按照它的作用效果可以剪切机分成两种：板材边缘剪切的圆盘剪、带钢剪切剪。

本论文的前期调查、资料搜集、结构设计、校核以及控制系统的设计计算都是通过在学校图书馆和实验楼的剪切机设备进行大量得调研背景下进行。在几个月对机器及相关设备的结构和控制系统的深入分析研究，以及在图书馆查阅机械设计手册、机械控制系统设计手册、机械原理、工艺学、经济学等书籍的基础上，对机器的主传动控制系统，主轴结构、减速箱、压下、侧间隙调整机构进行了设计。设计重点：电动机计算选取、轴和齿轮的设计，以及其他传动装置和执行机构的设计等，同时对部分主要零部件进行了强度校核。本次设计的改进点：一，在径向间隙调整机构连杆机构。二，增加自锁装置、侧向间隙调整。三，宽度调整采用行星齿轮减速机。最后增加了测速机构。

The disc alligator shears design

Abstract:The industry of various countries develops rapidly now, the steel, as the main pillar of industry, its development can reflect the national strength to a great extent. Modern steel metallurgy industry one starting point that develop in to processing speeds. Disc shears is an important equipment among them.

Disc shear machine set up in finishing production line. It usually uses to cutting neat the movement steel plate longitudinal edge and cut the strip into narrow one. It can be pided into two kinds according to its use: disc shears of cut stencil plate’s side and disc shears of cut strip.

The disc shears design calculation is taken in makes the massive investigation to the ANSHAN steel group Cold-rolling mill 1700 transverse cutting aircrew as the background. We have thorough understanding to the disc shears and the correlation equipment. We had very designed to the main transmission system, depress the system and gap adjustment organization, we are carry on these designs from the materials mechanics angle, dynamics and economic. The main content including electrical machinery selection, Axis and gear design, Implementing agency design and so on, and the same time, we make the optimized improvement and the intensity examination to the major parts. This design improvement spot: First, in radial clearance adjusting mechanism link motion gear, second, backlash adjustment increase self-locking installment. Third, the width control uses the planet gear speed reducer. Finally increased has measured the fast organization. This disc shears may use in the transverse cutting unit, the acid pickling unit generally and so on.

Keywords: Disc shear,strip,depress the system, the intensity examination
