In order to fix the axial relative position of the damping split pin and the sleeve, the round head end of the damping split pin needs to be flared.

[0003] The existing split pin flaring equipment on the market mainly flares the tail of the split pin, and there is no special equipment for flaring the round head end of the split pin; and the damping split pin has rotation and certain damping characteristics, so other automatic flaring equipment on the market cannot meet the flaring requirements of the damping split pin.
