PRESS AND METHOD OF PRESSED ARTICLE MANUFACTURING Russian patent published in 2019 - IPC B21D24/00 B21D22/26 B21D37/00 

FIELD: technological processes.

SUBSTANCE: proposed inventions relate to the field of metal forming by pressure and may be used in production of pressed articles. Manufacturing of pressed article is carried out on press in two stages. At the first stage, the concave part of the article is formed by stamping the workpiece using male die (13) and first matrix (11). Male die (13) has shape corresponding to shape of entire pressed article. First matrix (11) has the shape corresponding at least to the concave part shape of the product. At the second step, a vertical wall and a section of the rib line are formed by stamping using male die (13) and second matrix (12). Second matrix (12) is located in the press next to first matrix (11) and has the shape corresponding at least to the form of the vertical wall and section of the rib line of the product. First stage is completed after completion of the second stage.

EFFECT: enabling production of a pressed article having increased fatigue resistance.
