BILLET MOLDING Russian patent published in 2008 - IPC B21D26/02 B23K26/00 

FIELD: technological processes.

SUBSTANCE: billet is fixed next to matrix, then at least one part of billet is heated with laser controlled with the possibility of sending different levels of laser energy to different parts of billet up to temperature that is sufficient for achievement of superplasticity condition in it. Billet is affected with fluid pressure for shaping it as matrix. Method is implemented in device that contains facilities of matrix retention, facilities for billet clamping next to matrix with the help of clamping elements, facilities for application of fluid pressure to billet for shaping it as matrix surface, and also source of billet heating, at least, of billet part. As heating source laser radiation source is used, which is performed with the possibility of control of laser energy level, which is applied to different parts of billet. Item is produced by specified method.

EFFECT: provides precise monitoring of item shape.
