旋弯疲劳断料机设计中的几个基本问题

On Basic Problems of Designing a Rotating-Bending Fatigue Cutting Machine

金属棒料在旋弯交变应力作用下会发生疲劳断裂。将这一原理应用于断料行业 ,就发明了旋弯疲劳应力断料机。主要探讨旋弯疲劳断料机设计的基本原理、切口参数对疲劳断裂的影响、断料效率和断面质量的主要影响因素、旋弯疲劳断料的特点及适宜参数等基本问题。

Metal bar would be fractured under the rotating-bending fatigue alternating stress. Based on this theory a rotating-bending fatigue-cutting machine was invented and applied in manufacturing industry .So it's a kind of machine which takes advantage of fatigue-fracture .The achievements and advances in recent years are introduced in this paper,including effect of notch parameter on fatigue-fracture,the main factors effecting cutting efficiency and fracture quality,development and application of fatigue-cutting machine.
