Straightening machine

摘要

A straightening machine includes a frame supporting housings in which each housing receives a roll shaft rotatable about its axis. At least one first assembly includes a first guide defining a first convex surface and a first corresponding guided element defining a first concave surface. The first surfaces contact each other at a first contact surface. At least one second assembly includes a second guide defining a second convex surface and a second corresponding guided element defining a second concave surface. The second surfaces contact each other at a second contact surface. A device for rotating at least one roll shaft housing carries out a rotation being guided by the assemblies about a virtual axis transverse to a roll shaft axis, to compensate bending due to straightening of a product.

1. A straightening machine, comprising:
a frame; roll shaft housings supported by said frame, each of said roll shaft housings) receiving a roll shaft having an axis and being rotatable about the axis; at least one first assembly including a first guide defining a first convex surface and a first corresponding guided element defining a first concave surface, said first surfaces contacting each other at a first contact surface; at least one second assembly including a second guide defining a second convex surface and a second corresponding guided element defining a second concave surface, said second surfaces contacting each other at a second contact surface; and a device for rotating at least one of said roll shaft housings with a rotation being guided by said assemblies about a virtual axis transverse to the roll shaft axis to compensate bending due to straightening of a product.
