Laser thermal stress dieless forming device for TC4 titanium alloy sheet

The utility model discloses a laser thermal stress dieless forming device for a TC4 titanium alloy sheet, which is characterized in that the top end of a supporting bottom frame is fixedly connected with a mounting top plate, the two sides of the top end of the mounting top plate are fixedly connected with longitudinal moving frames, the tops of the longitudinal moving frames are provided with a transverse moving frame, and the top of the transverse moving frame is provided with a laser cutting head; the TC4 titanium alloy thin plate is jacked upwards through the driving rotating wheel, after the bottom face of the TC4 titanium alloy thin plate is separated from the top face of the supporting cone, the driving motor is started to drive the driving rotating wheel to rotate, and then the TC4 titanium alloy thin plate is driven by the driving rotating wheel to move horizontally. And after the TC4 titanium alloy sheet moves to a proper position, the driving rotating wheel descends to the bottom of the supporting
