一种铆压式斜槽铁心制造的新工艺及新装置

A New Technology and Device for Manufacturing with a Riveting Type Chute Core

对于铆压式斜槽铁心的制造,现有的2种制造工艺存在不同的问题:一种须采用高精度分度的冲床冲制冲片,对设备要求高,生产费用高,并对冲片的排放、叠压的次序要求极高,操作不便;另一种虽采用普通冲床冲制冲片,但铆压成型的斜槽铁心的铆钉孔呈轴向斜线,导致斜槽铁心的结构不稳定,易歪斜,质量不可靠,影响了电机的电气性能。经工艺改进,研制出了一种全新的铆压式斜槽转子铁心制造的工艺及装置。该方案采用普通冲床冲制冲片,降低了生产成本;操作简单、方便,生产效率高;且铆压成型的斜槽转子铁心的铆钉孔整体加工呈轴向直线,使铆压式斜槽转子铁心的结构稳定,质量可靠,确保了电机的电气性能。经实际应用表明,效果良好。

To the manufacture of riveting type chute cores,there are two kinds of existing manufacturing processes with different problems.A punching machine punching punching machine with high precision is required to produce high requirements for equipment and high production cost,and the sequence of the discharge and the pressure of the hedging sheet is extremely required,and the operation is inconvenient.Although the ordinary punch punching is existed,riveting rivet holes of the forming chute core are axially slash,making the chute core structure stable,easy to skew,quality reliable.Through process improvement,develop a new riveting type skewed rotor core manufacturing new technology and new equipment,reduce the equipment requirement,reduce the cost of production.It has the advantage of simple and convenient operation,high production efficiency.And the riveting molding skewed rotor iron core rivet holes of the overall processing is an axial line,effectively ensure the structural stability of the riveting type skewed rotor iron core,and ensure the electrical performance of the motor.The research has been applied,and achieves good results.
