Abstract
This article thesis is aimed at exploring the overall structure design of plate edge milling machine, that is the design of plank stuff edge milling machine, also called the design of board groove machine.At present,the design of plank stuff edge milling machine already has the certain development,and gradually tends to automation.
According to the principle of work and basic structure of plank stuff edge milling machine,the present thesis designs the plank stuff edge milling machine.On the base of these works, through regarding this topic analysis and consulting to some correlation books and literature, were further make clear that the overall design of plank stuff edge milling machine. This present thesis designs the plank stuff mill uses in the power plant before thealuminum sheet welding bevel to take shape. Designs should lie in with emphasis the design of the hydraulic system and milling system .
The main work achieved are summed up as following:
1.The related summary was made on the source and goal of task , Domestic and foreign development situation,existence problem.
2.The related summary was made on the general structure,then according to own demand selection suitable structure module.And a simiple narration was made on the overall design of plank stuff edge milling machine.
3.The related summary was made on the basic concept,characteristic,application and essential working procedure,and was further analysis the present situation and development direction.
4.The related summary was made on this design key point-milling system. Analysis was made on milling control system,and was further craft analysis the milling components.this has laid the foundation for the milling system of plank stuff edge milling machine.Finally,it has carried on the examination on each improtant size parameter of plank stuff edge milling machine.
In this paper a lot of experimental data about main point of plank stuff edge milling machine were acquired by studying the basic principle.This paper also will provide guidance for industrialization and researching plank stuff edge milling machine process.

前言
板材坡口机是一种使用最广泛的板材加工机械，早已实现了液压化,80年代迅速实现了数控化。据不完全统计，CIMT'95展出了18台板材坡口机，其中外国7台，中国11台。除了中国台湾的一台以外，其余的17台全部是数控板材坡口机。在我国历届国际机床展览会上,这一届展览会展出的板材坡口机最多，国产板材坡口机也很多，且水平较高。板材坡口机是用于焊接板材前打坡口的机械。对于普通板材坡口机来说，只有高度熟练的操作人员才能做好此工作，即使如此也需要相当长的调整时间。用先进的液压系统和数控系统装备的板材坡口机不但可以大大缩短调整时间，而且没有工作经验的操作人员也能生产出达到要求的板材坡口机。本文研究的板材坡口机用于铝板的坡口加工，具有很好的实用价值，这种板材坡口机控制系统由液压系统控制，铣削系统为核心系统。相对数控系统装备的板材坡口机其成本要低的多，而且对操作人员的熟练度要求较低。本文主要阐述了铣削系统、液压缸的设计以及液压控制系统的设计等内容。
