文档介绍：圆盘剪切机设计
摘要
现在各国工业迅猛发展,钢铁企业是国民经济的主要支柱,它的发展状况很大程度上可以反映出国家的实力。现代钢铁冶金业发展的一个着眼点就是在对钢材的处理速度。圆盘剪切机就是其中的一台重要设备。
圆盘剪切机通常设置在精整作业线上,用来将运动着的钢板的纵向边缘切齐或切成窄带钢。根据其用途可分为两种类型:剪切板边的圆盘剪和剪切带钢的圆盘剪。
本文中对圆盘剪切机的设计计算是在对鞍山钢铁集团公司冷轧厂1700横切机组大量调研的背景下进行的。通过对圆盘剪切机及相关设备结构进行了深入了解,并从材料力学、动力学和经济学的角度出发,对圆盘剪切机的主传动系统,压下系统、侧间隙调整机构进行了设计。重点包括电动机的计算选取、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:首先,在径向间隙调整机构连杆机构,其二,侧向间隙调整增加自锁装置。其三,宽度调整采用行星齿轮减速机。最后增加了测速机构。本圆盘剪切机可普遍用于横切机组、酸洗机组等。

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 divided 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 anization, 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 gear speed reducer. Finally
