Abstract
Cool bending tube useing pipe is the main method of tube forming.As the Development of society and technology,the more and more demand on bent-tube's Quantity and quality is proposed by many industries such as shipbuilding,automobile and heating. Especially in shipbuilding ,a lot of different kinds and high quality bent-tube are required for foreign ship.Tube processing has been a main factor on delivery time .In order to meet the demand,this article made a further,detail Study on the forming and measuring technology of bent-tube .to exploit an online non-contact measurement,that meet the processing needs of high-precision,and greatly shorten the production cycle.The dissertation consists of three chapters:
In chapter 1: Review bending machine angle measurement based on the technology of the angle measurement technique,and and elaborate Research on the content, purpose and topics of significance.
In chapter 2:Planning the program based on the bend angle detection system design the overall structure of Labview and IMAQ,and detailed describe the relevant theoretical framework from hardware and software and test and verify it by a lot of Authentication and Simulation.
In chapter 3:do the final summary by analysing error analysis of the system of measurement results
Key words:Angle measurement Online measurement Image Processing Non-contact
