The invention relates to a die-pressing
processing method for bar coils of a motor, and belongs to the technical field of motor coils. The die-pressing
processing method for the bar coils of the motor is characterized in that transposition is carried out from the straight line of the bar coils to two thirds of the end, and a lead wire welds the finished coils. The method comprises the following processes: 1) binding a main insulator: a, placing upper and lower bar coils on a coil bracket of a binding
machine respectively; b, adjusting the geometrical size of the end of the binding
machine, and arranging a required end elevating
cushion block at the end of the binding
machine; and c, binding the main insulator according to the compression amount given by the process; 2) treating an anti-halation structure; and 3) die-pressing
processing and molding, namely flatly wrapping a layer of
polytetrafluoroethylene film strip on the upper and lower bar coils, putting the bar coils into a bar coil die-pressing die respectively, providing current from the lead wire of the coils by adopting a pressurizing mode of a
hydraulic cylinder, and performing die-pressing processing and molding on the coils from the interior to the surface by adopting a curing mode and a heating method. The method has the advantages of simple process, high insulating strength, reduced
breakdown rate, long service life, high production efficiency, attractive appearance, and the like.
