Dry-type transformer coil forming die and dry-type transformer coil forming process

The invention relates to a dry-type transformer coil forming die and a dry-type transformer coil forming process, and belongs to the field of dry-type transformers. A dry-type transformer coil forming die comprises a forming die base, an outer forming die, an inner forming die and an arc-shaped cooling plate. The forming inner die comprises an inner die cylinder, a lower die plate arranged at the lower end of the inner die cylinder in a sleeving mode and an upper die plate arranged at the upper end of the inner die cylinder in a sleeving mode. The upper die plate is provided with an upper positioning groove used for allowing the arc-shaped cooling plate to be inserted therein. The lower die plate is provided with a lower positioning groove used for allowing the arc-shaped cooling plate to be inserted therein. The forming die base comprises a die base plate, a locking stand column installed on the die base plate, and a locking assembly installed on the locking stand column and used for pressing the forming out
