Abstract
Apparatus to guide a metal product, the apparatus includes a support body (11). A plurality of support arms (12) are associated with the support body (11). A plurality of guide rolls (13) are installed rotating in an idle manner on the support arms (12) and define between them a roller guide gap (14) for the metal product. Adjustment devices (24) associated with the support arms (12) and adjust, independently from each other, the position of each of the guide rolls (13. Detection devices (19) detect the stresses induced by the metal product on the guide rolls (13).
Claims10
Apparatus to guide a metal product, said apparatus comprising, a support body (11), a plurality of support arms (12) associated with said support body (11), and a plurality of guide rolls (13) installed rotating in an idle manner on said support arms (12) and defining between them a roller guide gap (14) for said metal product, wherein a respective adjustment device (24) is associated with each support arm (12) and configured to adjust, independently from the other adjustment devices (24), the position of each of said guide rolls (13), and wherein said apparatus comprises detection devices (19), each associated with one of said support arms (12), configured to detect the stresses induced by said metal product on each of said guide rolls (13), wherein each adjustment device (24) comprises its own drive member (27) selected between an electric rotary motor and an electric linear actuator to adjust the position of each of said guide rolls (13), and wherein said apparatus comprises a control and command unit (29) connected to said detection devices (19) and to said drive members (27), and configured to command the drive of the respective one of said drive members (27) as a function of data detected by said detection devices (19).
-3. (canceled)
Method to guide a metal product exiting from or entering into a rolling apparatus (110), which provides to make said metal product pass through a roller guide gap (24) defined by guide rolls (13) installed, rotating in idle manner, on support arms (12), said support arms (12) being associated with a support body (11), said method including the adjustment of the position of each of the guide rolls (13), independently from each other, with adjustment devices (24) each associated with one of the support arms (12) and the detection, with detection devices (19), each associated with one of the support arms (12), of the stresses induced by the metal product on the guide rolls (13), wherein each adjustment device is driven by its own drive member (27) selected between an electric rotary motor and an electric actuator to adjust the position of each of the guide rolls (13), said drive being commanded by a control and command unit (29) that detects the data from said detection devices (19) and commands the respective one of said drive members (27) as a function of said data.
