Research On Hydraulic Bulging Processing Technology Of Stainless Steel Tee

The hydraulic bulging of ss t joint is a forming process that expands the branch pipe through axial compensation of metal materials. The process is to use a special hydraulic press to inject liquid into a tube blank with the same diameter as ss tee 1 2, and squeeze the tube blank through the synchronous centering movement of the two horizontal side cylinders of the hydraulic press. The tube blank becomes smaller in volume after being squeezed, and the pressure of the liquid in the tube blank increases as the volume of the tube blank decreases. When the pressure required for the expansion of the ss tee fitting branch pipe is reached, the metal material flows along the inner cavity of the mold under the dual action of the side cylinder and the liquid pressure in the tube blank to expand the branch pipe.
