Title    Physical Design and Performance Analysis of the High-Precision Four-Roll Bender                          

Abstract

The continuous four-roll bending of sheet is one of the metal stamping process. It puts pressure on the plastic deformation directly in the roll bender,for a certain shape , size and mechanical behavior, by using the power produced from stamping equipment. However, the understanding of the bending operational mechanisms is still in its infancy, and its operation, at the present stage, still depends heavily upon the skill of operators. This restricts the flexible use and development of the four-roll bender. Therefore, this article optimize the structure of high-precision four-roll bender and analyze the mechanical behavior. The specific work of the high-precision four-roll bender which the article complete as following: 

Firstly, find and read the relevant literature, to understand current research about high-precision four-roll bender, put forward feasible program of the high- precision four-roll bender. 

    Secondly, design and calculate the proposed scheme. Combined with mechanical design manuals and references, according to the actual job requirements, design and calculate high-precision four-roll bender meets your needs, and draw three-dimensional structure of the high-precision four-roll bender and the drawing of important parts. 

    Thirdly, use finite element analysis software to carry on performance analysis and strength check for the key components of the high-precision four-roll bender. 

Keywords    high-precision four-roll bender
