Abstract:
A shearing and coiling assembly for hot rolled stock such as strip or sheet with a thickness varying from 0.5 to more than 5 mm, comprising:a rolling train (100) which defines a substantially horizontal plane of feed (14),a shearing assembly (11) suitable to shear selectively the rolled stock anda coiling machine arranged downstream from the shearing assembly (11) to selectively wind the stock sheared by the shearing assembly (11),wherein the coiling machine (10) comprises a turntable assembly (12) rotating around a central axis of rotation (13) parallel to the plane of feed (14) and two coiling mandrels (15a, 15b) mounted rotary on the turntable (12) on diametrically opposite sides with respect to the central axis of rotation (13) and with their axes of rotation parallel to the central axis of rotation (13),the shearing assembly (11) is mounted sliding on first guide means (50) arranged transverse to the plane of feed (14) and is selectively movable between a first working position, in which the shearing assembly (11) is aligned with the plane of feed (14), and a second inactive position, in which the shearing assembly (11) is distanced from the plane of feed (14),a rollerway (16), arranged on a substantially horizontal plane, is mounted sliding on second guide means (62) arranged transverse to the plane of feed (14) and is selectively movable between a first working position, in which the rollerway (16) is aligned with the plane of feed (14), and a second inactive position, in which the rollerway (16) is distanced from the plane of feed (14),when the shearing assembly (11) is in the first working position, the rollerway (16) is in the second inactive position and vice versa, andthe coiling machine (10) is suitable to assume an inactive position when the shearing unit (11) is in the second inactive position and the rollerway (16) is in the first working position.
