The hydraulic bulging forming process of the stainless steel butt welding tee refers to a forming method that expands the branch pipe through the axial compensation of the metal material.
Forming process: Use a special hydraulic press to inject liquid into the tube blank with the same diameter as the tee, and use the hydraulic press to squeeze the tube blank through the synchronous centering motion of the two horizontal side cylinders. After the tube blank is squeezed, the volume becomes smaller, and the tube blank As the volume of the tube shrinks, the pressure of the liquid increases, and when the pressure required for the expansion of the tee branch is reached, the metal material flows with the inner cavity of the mold under the dual action of the liquid pressure in the side cylinder and the tube, and expands the branch.
This process can be formed at one time, and the production efficiency is relatively high. The wall thickness of the main pipe and shoulder of the stainless steel tee will increase.
