Abstract (en)
Rolling machine for forming a thread on cylindrical bodies, which comprises two or more forming rollers (6), mechanically associated with the support structure (2) and adapted to plastically deform a cylindrical body arranged along a central work axis (A) of the machine (1). Each forming roller (6) is provided with a thread (8), is driven to rotate around its rotation axis (Z) by a brushless motor (16) and is driven to be moved along a respective first transverse axis (R) perpendicular to the work axis (A) by a corresponding hydraulic piston (15). Sensor means (30) are provided that are mechanically mounted on the support structure (2) and drivable to be moved by movement means (35) between a non-operative position (P1), in which they are in distal position with respect to the forming rollers (6), and an operative position (P2), in which they are in proximity to at least one forming roller (6) in order to detect the axial position of its thread. The invention also relates to a process for phasing the forming rollers of such a rolling machine.
