The hot pressing forming of a tee is to flatten the tube blank larger than the diameter of the tee to the size of the tee diameter, and open a hole in the part of the stretching branch pipe; After being heated, the tube blank is put into the forming die, and the die for drawing the branch pipe is put into the tube blank; Under the action of pressure, the tube blank is compressed radially. In the process of radial compression, the metal flows to the branch and forms the branch under the drawing of the die.
