【摘要】：介绍了电机转子铁芯自动叠铆的原理、铁芯自动叠片形成的过程及其关键技术。以某电机转子为例,分析了电机转子结构特点和其冲压成形工艺方案。结合生产要求,提出采用级进模自动叠铆技术制作电机转子铁芯。通过4种排样方案对比,选出材料利用率最高的排样方案,并进行级进模工位设计。然后完成冲裁力、压力中心、模具工序尺寸等方面的冲压工艺计算。确定模具主要零件的结构形式,设计了模具总体结构并给出模具装配图。结果表明:电机转子叠片采用一套自动叠铆级进模成形,可连续进行冲叠铆点、落料、叠铆工序,实现高精度和高效生产。
[Abstract]:This paper introduces the principle of automatic stacking riveting of iron core of motor rotor, the forming process and key technology of iron core automatic lamination. Taking a motor rotor as an example, the structure characteristics of motor rotor and its stamping forming technology are analyzed. This paper puts forward to use progressive die automatic folding riveting technology to make iron core of motor rotor. Through the comparison of four layout schemes, the layout scheme with the highest material utilization ratio is selected, and the progressive die station design is carried out. Then the blanking force and pressure center are completed. The stamping process calculation of die process size, the determination of the structure of the main parts of the die, the design of the overall structure of the die and the assembly diagram of the die are given. The results show that the motor rotor lamination is formed by a set of automatic folding and riveting progressive dies. Continuous stamping riveting point, blanking, folding riveting process to achieve high-precision and efficient production.
