Abstract
For metals with large material thickness,if you want to get round,rolling arc,conical structure by rolling,four-roll bending machine is a  great suitable means .there are some distinctive features,such as preflex at the end of sheet material to avoid the circumstance of not aligned at both ends when welding;High efficiency and less remaining part at the end of sheet material;By using its self function,to adjust the sheet material probably,it’s incomparable for two or three roller bending machine. The research and solution point of my graduation design is ,By investigate the research condition of four-roll bending machine at home and aboard, designing and calculating the mechanical structure,analysing the property of key component,to process sheet material thickness 60 mm,length 2000 mm.
This paper completed by four steps ,first of all,On the base of knowing the existing structure and theory of four-roll bending machine at home and aboard,I've summarized and analyzed it to work out literature review.secondly,On the base of now existing mechanical structure of bending machine,I've defined  the structure optimization of  four-roll bending machine ,so that i could draw  three dimensional structure and engineering drawing of the sample by solidworks.moreover,through finite element analysis software,ansys,checked the strength and analyzed the performance of the key component,summarized my thesis.
Keywords  four-roll bending machine,three-dimensional design  structural optimization,   performance analysis
