Effect of drawing conditions in tandem pass drawing on drawn diameter

摘要

In recent years, high-quality drawn bar and wire have been required for automobile components and office equipment. Tandem pass drawing is one method of reducing residual stress generating back tension between dies. However, this method makes it difficult to control diameter change. Therefore, the authors investigated the effect of drawing conditions in tandem pass drawing on drawn diameter. The results indicate drawn diameter is greatly affected by reduction allocation.
