锥辊楔形异步轧制是在当今世界上生产螺旋叶片最先进的锥辊异面辗轧工艺的基础上提出的一种新构思。它克服了后者设备调整困难和螺距不能过小的缺点。本文重点运用上界法计算了轧制力矩,然后在自制的设备上进行了实验验证。 Tapered roller wedge asynchronous rolling is a new idea put forward on the basis of the most advanced conical roller rolling process in the world today. It overcomes the latter equipment adjustment difficulties and the pitch can not be too small shortcomings. This paper focuses on the use of upper bound method to calculate the rolling torque, and then made a self-made equipment on the experimental verification.
