楔横轧技术应用与研究

Defects analysis and improvement for the cross wedge rolling process

楔横轧作为一种精密成形工艺,广泛应用于各种台阶轴类件的生产。但由于其成形机理较为复杂,该工艺仍然存在一些常见缺陷,如表面缺陷、中心疏松等。本文对工艺缺陷进行了分析研究,并采取措施改进。楔横轧工艺是轴类件毛坯生产的理想的工艺,值得推广应用。

The defects of the cross wedge rolling process have been analyzed and studied carefully in the text. The improving measures have been adopted. It is believed that the cross wedge rolling process is ideal for the production of shaft blank, which is worthy of application and popularization.
