The hydraulic bulging of equal diameter four-way hydraulic bulging is a forming process of expanding branch pipe by axial compensation of metal material. The process is to use a special hydraulic press to inject liquid into the tube blank with the same diameter as the four-way pipe, and extrude the tube blank through two horizontal side cylinders of the hydraulic press synchronously. The volume of the tube blank becomes smaller after being extruded, and the pressure of the liquid in the tube blank increases with the volume of the tube blank becoming smaller. When the pressure required by the expansion of the four-way pipe is reached, the liquid pressure in the side cylinder and the tube blank of the metal material is double Under the heavy action, the branch pipe flows along the inner cavity of the mold and expands.
