PRESS FOR SHEET PRESSWORK Russian patent published in 2009 - IPC B21D26/02 B30B5/02 

FIELD: metallurgy.

SUBSTANCE: press contains bottom part of punch with cavities, top part of punch in the form of matrix with cavity, from one to ten steam generator and high-pressure pump 20-50 MPa for water feeding. Top part of punch is installed movable by means of lifting gear. Steam generator is implemented in the form of envelope, external pipes with left and right blind and installed in cavity of defined external pipes internal pipes, and has a drive with electric motor. Internal pipes of steam generator have located inside incandescence conductor. Defined incandescence conductors are connected with primary and secondary winding of transformer. Transformers are located at ends of internal pipes on side walls of envelope. Left blinds of steam generator eternal pipes are implemented with sprayer, which are connected by means of pipelines with high-pressure pump. Steam generators external pipes are connected to bottom part of punch. High-pressure pump are appropriate for water feeding from water-supply network into steam generator. Electric motor is implemented with ability of its disconnection by means of time relay from electric mains each 0.1-600 s after feeding by pump water portion into steam generator. Bottom part of punch is outfitted by installed at its top side resilient member.

EFFECT: improvement in details manufacturing accuracy.
