摘要
AP1000核电弯管采用超低碳控氮不锈钢整体锻造技术锻造,管道强度高、管长孔深、弯曲角度大、弯曲段弧面长。传统加工方法需要多台机床进行组合加工,成本高、耗时长,而且加工出来的成品的精度也不高。为了实现在单台加工设备上高效率地加工AP1000核电管道,提出了一种加工弯管内孔的新方法——随动加工法,通过将加工装置放置在弯管内部并通过旋转关节和传动杆传递动力,使加工装置沿着弯管内壁中心线加工。只要旋转关节工作满足运动参数的要求,就能实现随动加工,提高弯管的加工效率和精度。
AP1000 nuclear power elbow was forged by ultra-low carbon nitrogen stainless steel Integral forging technology, it has high strength and the length and depth is relatively large. The length of curved segment of cambered surface was so long. Traditional processing methods require more than one machine composite processing which caused high costs, time-consuming and the precision of the finished product is not excellent. In order to achieve the purpose of the high efficiency AP1000 nuclear power pipeline processing on a single processing equipment, a new methods have been put forward for processing the elbow hole-the kinematic processing. This method making processing device installed in the elbow and providing power through a special device, so that processing device could work along with the center line of bends. As long as the rotary joint satisfies the requirements of the motion parameters, the kinematic processing would be able to improve the processing efficiency and accuracy.
