【摘要】：介绍了发电机定子铁心用通风槽钢生产工艺,针对通风槽钢切断和弯形工序,设计了一种新型的切断弯形工艺,在一副模具上同时完成切断、弯形、整形3道工序。在分析槽钢切断弯形特点及其变形规律的基础上,对槽钢成型过程做出合理简化,建立分析模型,利用有限元软件对槽钢切断弯形进行了三维有限元数值模拟分析,得出了槽钢在成形过程中的几何变形情况。对不同冲头形状进行了对比分析,并在实际生产中很好的控制了槽钢切断后存在的塌肩、毛刺等缺陷。
[Abstract]:The production process of ventilated channel steel for stator core of generator is introduced. A new type of cutting and bending process is designed aiming at the cutting and bending process of ventilated channel steel. Three processes of cutting, bending and shaping are carried out simultaneously on a set of dies. On the basis of analyzing the characteristics of channel cutting bending and its deformation law, the forming process of channel steel is reasonably simplified, the analysis model is established, and the three-dimensional finite element numerical simulation of channel steel cutting bending is carried out by using finite element software. The geometric deformation of channel steel in forming process is obtained. The different punch shapes are compared and analyzed, and the defects such as shoulder sloughing and burr are well controlled in actual production.
