摘要

本文简要介绍了轧钢设备的地位、作用和飞剪机的应用发展现状，对各种类型的飞剪机的结构和用途进行了介绍和对比。重点研究了双曲柄对称式飞剪机设计的三个关键点：机构的确定、结构设计及运动学分析。
本飞剪机设计成双曲柄对称式飞剪机，其设计特点是将刀架作成杠杆形状，将其一端固定在偏心轮的一端，另一端固定在摆杆上，使得偏心轮转动时，刀架能够作平移运动，则令固定在刀架上的刀片能够作垂直或近似的垂直于轧件的运动，从而使得剪切断面能够比较平整。
本文根据剪切过程的运动要求对飞剪机的力能参数进行计算，利用得到的力能参数进行了电动机的选择与验算，然后对一级减速器和带传动进行设计，轴和轴承的强度校核符合设计标准，工作安全可靠。

Abstract

The brief almostly introduced the degree and effect of steel rolling equipment, the flying shear's development and present status of the application. We also make a introduction and contrast about the use and structure of various plate mill flying shears.Focused on considering the three points of the three symmetrial flying shear : the determination of the institution, optimization and kinematic analysis.
The flying shear is crank rocker- type, which is characterized by forming the knife rest into lever type, and fixing one end on jackshaft while the another on oscillating bar.So the knife rest can make translationmotion following the rolling of jackshaft which orders the blades fixed on the knife rest make vertical- rolling or approx vertical- rolling to get a smooth cut section.
In this paper we calculate the energy parameters according to the movement requirement of the shearing process. Then we choose a motor and make a checking using the parameters.We also design the reducer and belt drive,then check the strengthen of axle and bearing. The flying shear fit the design requirements totally,safety and reliable.

Keywords: flying shear, architectural design, energy parameters,check
