Beneficial effect: this utility model SMIS tire is that the cooperation of core lobe forms, and core tire endoporus is by the bellmouth being gradually reduced between upper to lower, be slidably matched in this bellmouth swelling tire, i.e. meeting extrusion die lobe while swelling tire moves, core lobe is promoted radially to move along backing plate, the distance of adjacent core lobe increases, the diameter making core tire increases, it is enclosed within core tire outside during due to the axis hole of stator punching, core tire will completely and stator punching axis hole fully in contact with, namely the axle center of stator is the axis of core tire, so prevent from, when some stator punchings are stacking, skew occurs, alignment accuracy is high；On the other hand, due to the variable diameter of core tire, being therefore applicable to the lamination of the stator punching of different pore size in certain limit (i.e. the axis hole aperture of stator punching), versatility is stronger；Finally, cause swollen bad stator punching axis hole to prevent core tire from excessively increasing, the lower clamping ring inner circle opposite face with core lobe is provided with supporting position limiting structure, the movement of core lobe is carried out spacing.

Further, the quantity of described core lobe is three, is equipped with embedding cutting on each core lobe is vertical, embeds filler rod and insert the mark groove on stator punching when core lobe moves, it is ensured that the mark groove alignment of stator punching.

Further, also including moveable screw rod, described swelling tire is the bullet that diameter is from top to bottom gradually increased, and screw rod runs through base from the bottom to top threadeds with swelling tire lower end, and drive swelling tire is moved by the movement of screw rod.

Further, described position limiting structure includes the limiting stand that core lobe lower end cylindrical convexes to form and the stopper slot that lower clamping ring inner circle depression is formed, and core lobe moves to lower clamping ring inner circle, and namely limiting stand inserts in stopper slot, and core lobe then stops mobile.

Further, described lower clamping ring and backing plate are fixed by hexagon socket cap head screw, connect more firm.
