摘要：

软磁合金筒形件因具有优良的抗磁干扰能力而广泛应用于电磁领域，针对传统制备工艺中零件易漏磁及材料浪费严重等缺点，提出采用流动旋压来实现其近净成形。对冷硬态的1J50软磁合金管坯进行了再结晶退火以获得良好的塑性，随后进行筒形件流动旋压成形试验，以壁厚偏差、椭圆度、直线度和粗糙度为评价指标，分析了进给比、旋压道次对成形质量的影响。结果表明：当进给比为0.4~0.8 mm·r-1时，工件成形质量较好，当进给比大于0.8 mm·r-1时，成形质量急剧变差，因此，综合考虑旋压件的成形质量和生产效率，推荐采用0.8 mm·r-1的进给比进行流动旋压；随着旋压道次的增加，壁厚偏差和粗糙度逐渐减小，而椭圆度和直线度略有增加。

Soft magnetic alloy cylindrical part is widely used in the electromagnetic field because of its excellent ability of anti-magnetic interference. To overcome defects of magnetic leakage and material waste in the traditional manufacturing, the flow spinning was put forward to realize the near-net forming, and the cylindrical part made of soft magnetic alloy 1J50 under the state of cold hard was treated by recrystallization annealing to obtain good plasticity. Then, the flow spinning was researched experimentally, and the influences of feed rate and spinning pass on the forming quality were analyzed by evaluating index of forming quality of the wall thickness deviation, ovality, straightness and roughness. The results show that the high forming quality can be obtained within the feed rate of 0.4-0.8 mm·r-1, while the quality becomes worse dramatically when the feed rate is greater than 0.8 mm·r-1. So, the flow spinning with a feed rate of 0.8 mm·r-1 is highly recommended under the comprehensive consideration of forming quality and production efficiency. With the increase of spinning passes, the wall thickness deviation and roughness decrease, while the ovality and straightness increase slightly.
