Granulator compression roller loose tooling forging die and forging method thereof

The invention discloses a granulator compression roller loose tooling forging die and a forging method thereof, relates to the technical field of granulator compression roller loose tooling forging, and aims to solve the problems that the forging work is too troublesome and the working efficiency is reduced since a worker needs to replace the die for multiple times and the die needs to be disassembled, assembled and carried for multiple times due to need of a plurality of steps when an existing granulator compression roller is forged through the die. The granulator compression roller loose tooling forging die is characterized in that a dovetail sliding groove is formed in the upper end face of a fixed seat; a movable seat is arranged above the fixed seat; the lower end face of the movable seat is attached to and slidably connected with the upper end face of the fixed seat; an insertion sliding block is fixedly arranged on the lower end face of the movable seat; the insertion sliding block is inserted into the
