Motor rotor pole coil arc pressing die and arc pressing method thereof

The invention relates to the technical field of coil arc pressing dies, and discloses a motor rotor pole coil arc pressing die which comprises an arc pressing die bottom plate, the two sides of the upper end of the arc pressing die bottom plate are each connected with two arc pressing die two-side-edge blocks through a positioning mechanism, and the two arc pressing die two-side-edge blocks are symmetrically distributed about the center line of the arc pressing die bottom plate. An arc pressing mold middle mold core and two arc pressing mold two-end mold cores are installed in the center of the arc pressing mold bottom plate, and an arc pressing mold arc pressing ring is arranged at the upper end of the arc pressing mold bottom plate and pressed at the upper ends of the arc pressing mold middle mold core and the two arc pressing mold two-end mold cores. Two symmetrically-arranged arc pressing die lower pressing blocks are placed at the upper end of the arc pressing die bottom plate and located on the two side
