Study on Titanium Precise Profile Wire Process by Roller-die

The reason why it is difficult to process the titanium precise profile wire is analyzed, and principles, characteristics and superiorities of the roller-die are simply stated. After the four-roUer-die has been designed and manufactured, the titanium precise profile wire can be processed in practice. The practice and the results are introduced, and the method of four roller-die drawing is discussed too. The result shows that the adoption of the four roller-die to process the titanium precise profile wire can overcome the weakness of titanium high resistance to deformation and difficulty in processing, decrease the drawing force, increase the working moduins and the drawing speed, and lower the production cost as a consequence.
