COMPACTED COMPONENT AND METHOD AND DEVICE FOR ITS MANUFACTURE Russian patent published in 2017 - IPC B21D22/26 

FIELD: metallurgical engineering.

SUBSTANCE: invention can be used for manufacturing from a sheet metal having a tensile strength of 500 to 1800 MPa, a compacted component that has a hat section and is L-shaped along the longitudinal direction. The upper flat section of the rolled metal is pressed and pressed against the punch by a cushion. The portion that will be located outside the L-shaped bend is compressed and pressed against the die by the workpiece holder, the bending device is being moved and form a vertical wall section on the inner side of the L-shaped bending of the metal sheet and a flange section connected to the vertical wall on the inner side of the L-shaped bending. Further, the metal rolled sheet is moved towards the position of the workpiece holder while maintaining the state in which the metal rolled sheet is pressurized and pressed against the die by the workpiece holder and a vertical wall section is formed outside the L-shaped bending of the L-shaped hat section and the flange section, connected to the vertical wall on the outside L-shaped bending.

EFFECT: formation of folds or cracks in the component is eliminated.
