The Process Of Hydraulic Bulging Of Cold Drawn Stainless Steel Tees
Date: | Read: 36
The volume of the tube billet becomes smaller after being squeezed, and the pressure of the liquid in the tube billet increases as the volume of the tube billet decreases. When the pressure required for the cold-drawn 1 4 stainless steel tee branch tube to bulge out 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 billet and bulges out the branch tube.
