Compressive torsion forming device

A compressive torsion forming device for processing a processing material using a first die and a second die facing each other, the compressive torsion forming device comprising:

• a sliding portion that includes a first hydraulic chamber, and slides in accordance with a change in internal pressure of the first hydraulic chamber so as to move the first die in a direction of an axis;
• a rotating table provided with the second die and rotatable about the axis;
• a table support portion provided opposite to the second die with the rotating table interposed therebetween in the direction of the axis;
• a rotational thrust bearing that rotatably supports the rotating table with respect to the table support portion, and receives a force acting on the rotating table in a direction from the second die toward the rotating table;
• and
• a second hydraulic chamber that is provided between the rotating table and the table support portion and communicates with the first hydraulic chamber,
• wherein the rotational thrust bearing is provided inside the second hydraulic chamber.
