Design of drafting mechanism for FA322B drawing frame
摘要
Abstract
In order to improve drafting effect of FA322B drawing frame,optimized design of drafting mechanism is analyzed.Sensitivities of structural parameters of main drafting area on drafting effect are analyzed firstly,and parameters which have high impact on drafting effect are gained.Then these parameters as variables and distance of gripped slivers as objective function are chosen,and the main drafting area is optimized.Two conclusions are confirmed from the above analysis and optimization.First,minimum griping distance of slivers and minimum arc surrounding front roller can not be found synchronously.Therefore the balance between them should be well kept while optimizing the drafting mechanism.Second,both radius of second under-roller and position of press bar have great impact on the drafting.So these parameters should be designed properly.关键词
