Research on TC4 Alloy Wire Rod Straightening Process

摘要

Titanium alloy are widely used in various fields, such as Aerospace, Marine and Medical. However, the technology of straightening for TC4 wire rod has not been effectively solved, and relevant research is quite rare. TC4 wire rod is difficult to be straightened under room temperature owing to its special properties. In order to solve this problem, this paper designed a parallel roll thermal straightening system and also developed an automatic intermesh calculation software based on Matlab GUI platform to precalculate the settings of straightening device under different temperatures according to straightening theory. Furthermore, numerical simulation method has been used for straightening process with ABAQUS software before the practical straightening experiment. Finally, using the calculated parameters the straightening experiment was carried out, and results show that this method is feasible and effective.
