AN ELECTROMECHANICAL ACTUATOR FOR PRESS BRAKES

摘要

An electromechanical actuator for press brakes, includes: an outer containment body (13); a lead nut (5) positioned within the outer body (13) and presenting a threaded internal surface (9); a stem (2) able to be associated to a bending tool and having a thread (4) operatively associated within the lead nut (5); motor element (6) positioned in the outer body (13) to set in rotation the lead nut (5) around its own longitudinal axis (X), the rotation of the lead nut (5) determining the axial displacement of the stem (2); and at least one tie rod (20) fastened within the containment body (13) to absorb the axial loads (C) applied on the stem (2); the axial loads (C) are transferred from the stem (2) to the tie rod (20) by transfer element (24).
