The invention belongs to the field of metal material plastic processing and discloses an electromagnetic lateral edge turning device for a pipe with a preformed hole. The device comprises an upper die frame, an upper die, a lower die, a lower die frame, a columnar supporting body, a space spiral coil and a pulse discharge circuit. The upper die is arranged on the upper die frame, the lower die is arranged on the lower die frame, a containing hole is formed by the upper die and the lower die jointly, and the pipe with the preformed hole is sleeved with the columnar supporting body. An edge turning hole is formed in the upper die, the pulse discharge circuit and the space spiral coil are connected to form a pulse magnetic field, the top view of the space spiral coil is spiral, and the side view of the space spiral coil is arc. The space spiral coil is arranged on the top of the columnar supporting body, and a groove for containing the space spiral coil is formed in the top of the columnar supporting body. Radial electromagnetic force generated by the space spiral coil is distributed more intensively in an edge turning hole region, the electromagnetic force is higher, the energy utilization rate is higher, the service life of the coil is longer, and good economic benefits are achieved.
