[0002] The stator is the stationary part of a motor or generator. The stator is composed of a stator core, a stator winding and a machine base. The stator winding is copper wire wound on the stator. The stator winding can be wound by a flying fork winding method. The flying fork nozzle carries enameled wire. The die part moves forward. After positioning, the die tongue is clamped in the stator slot. Then the die tongue continues to move forward to the winding starting point. It starts to retreat backward. At the same time, the flying fork rotates at high speed to drive the nozzle to wind the wire. The enameled wire is wound in the stator slot one turn after another under the guidance and constraint of the die tongue. Since the die tongue of the prior art does not have good support, it is easy to cause shaking during flying fork winding, resulting in wire jamming during winding. SUMMARY

[0005] Further, the mounting seat is cylindrical, and an insert is integrally formed in the mounting seat, the insert is located on both sides of the center line of the mounting seat with the eccentric mounting hole.
[0006] Further, the die tongue assembly comprises a die tongue seat, fixed blocks, a guide block and a die tongue block, one end of the die tongue seat is embedded in the eccentric mounting hole, and the other end is fixedly connected with the end face of the mounting seat, the fixed blocks are symmetrically fixed on the end face of the die tongue seat, one end of the die tongue block is clamped in the die tongue seat, the other end of the die tongue block extends out of the die tongue seat and is located between the fixed blocks, a spring is arranged between the die tongue block and the mounting seat, and the end of the die tongue block away from the spring is fixedly connected with the guide block.
[0007] Further, the die tongue seat is provided with symmetrical long strip-shaped holes, and the fixed blocks are provided with fixed holes corresponding to the long strip-shaped holes.
[0008] Further, the two side faces of the fixing block are provided with symmetrical guide grooves, and the guide block is provided with a guide part matched with the guide grooves.
