Variable wall thickness pipe processing technology and mould design

WEN Jian-ping(Department of Mechanical Engineering,Hengyang Industry Vocational College of Finance and Economics,Hengyang 421001,China)  
Under the condition of ensuring the part strength and rigidity,the variable wall thickness pipe was used in order to reduce the part weight.Variable wall thickness pipe was usually processed by turning technology.In order to reduce the production costs,and improve the product quality and production efficiency,the bicycle riser part processing procedure and die structure were studied through process test.The new method of cutting,necking,annealing,surface treatment,pipe drawing,flatting and chamfering was used instead of the turning process.The production practice proves that the expected goal is reached and good economic results are achieved.
