1145型曲柄连杆飞剪机
摘要
线材生产中飞剪机是用来切头、切尾和进行事故的处理,它在整个线材生产流水线上是必不可少的。飞剪机有很多类型,我设计的题目是“1145型曲柄连杆飞剪机”,采用单电动机传动方式,机身自带一级减速器,两个刀架沿相反的方向运动从而切断轧件。
在这次设计中,我完成了以下工作:选择和确定了设计方案:选择和校核了合适的电动机:设计和校核了主要的零部件;确定了合适的润滑系统和维修维护方案。
关键词:飞剪机;单电动机传动;一级减速器;切断轧件。
1145-crank rod flying shear
Abstract
In the process of producing wire rod, flying shears is used to cut head and end as well as deal with accidents , and it is necessary , Flying shears have many types .Our subject is the design of 1145 carving shears. We adopt a mean that one motor which have a decelerating machine on itself drives the power and two shears moving from two reverse directions in order to joint the objects.
In this design: we have plished the following works: selecting and defining design scheme; choosing and checking and checking suitable motor; designing and checking the main parts; defining a proper lubricating system and a maintain scheme.
Key words: Crank flying shear; Single-motor drive; A reducer; Cut workpiece.
