STRAIGHTENING MACHINE Russian patent published in 2018 - IPC B21D3/05 

FIELD: molding.

SUBSTANCE: invention relates to a straightening machine. Straightening machine comprises a frame supporting housings. Each housing receives a roll shaft rotatable about its axis. Machine comprises at least one first assembly, at least one second assembly, means for rotating at least one roll shaft housing. First assembly comprises a first guide defining a first convex surface and a first corresponding guided element defining a first concave surface, said first surfaces contact each other at a first contact surface. Second assembly comprises a second guide defining a second convex surface and a second corresponding guided element defining a second concave surface, the second surfaces contacting each other at a second contact surface. Rotation is guided by the assemblies about a virtual axis transverse to the roll shaft axis, to compensate bending due to straightening of a product.

EFFECT: as a result, it is possible to determine a rotation center.
