平砧自由锻拔长效率研究

Research on Drawing Efficiency in Free Forging

平砧上自由锻拔长,送进量的大小对其拔长效率起着至关重要的作用。理论上一般认为采用小送进量,就能取得较大的拔长效率,这一表述非常含糊。通过DEFORM-3D数值模拟和实验的方法,给出了这一问题的明确概念,这对于提高拔长效率,指导实际生产具有重要的意义。

As free drawing on the flat anvil, the size of feed plays the very important role to its drawing efficiency. It is extremely ambiguous that the former textbook says a big drawing efficiency can be obtained through using slight feed. This article gives explicit concept about this question through the DEFORM-3D numerical simulation and experiment. It is vital significant to how to enhance drawing efficiency and instruct actual production.
