Pipe fitting forming die and pipe fitting forming method

The invention discloses a pipe fitting forming die and a pipe fitting forming method. The technical problem that in the prior art, the pipe fitting forming precision is low is solved. The pipe fitting forming die comprises a support. The male die assembly comprises a male die with a convex surface; the female die assembly comprises at least two half dies, at least one half die can turn over relative to the support, and the half dies are provided with concave surfaces; the male die driving assembly is used for driving the male die to enter or leave the female die assembly; the female die driving assembly is used for driving the at least one half die to turn over relative to the bracket, so that the female die assembly is switched between an opening state and a closing state; under the condition that the female die assembly is in an open state, an opening for the male die and the blank to enter or leave is formed between the at least two half dies; when the female die assembly is in a closed state and the male
