Embodiment Construction
[0018] figure 1 It is a schematic diagram of the warm extrusion of the herringbone channel die of the present invention: 1. Initial state: put the processed titanium alloy billet into the die cavity of the herringbone channel die; At the beginning of pressing, the mold is warmly extruded through the herringbone channel, and at the same time, the back pressure rod returns to its position when the punch goes up after the back pressure is applied to the billet in the cavity of the horizontal mold channel. Rotate the herringbone channel mold; 3. After the herringbone mold is rotated 120°: the second plastic deformation of the titanium alloy material can be realized.
[0019] figure 2 It is the herringbone channel die warm extrusion die and accessory device of the present invention: 1. Put the processed titanium alloy billet into the cavity of the herringbone channel die; 2. The punch goes down, when the punch and the billet contact extrusion, Warm extrusion is carried out throu...
