Dispositivo para bruñido y pulido de piezas metálicas

摘要

The invention relates to a device for burnishing and smoothing metal parts, particularly suitable for use in mechanical-galvanic processes, comprising a main body (3) having a securing disc (6) to which guides (7) are radially coupled and the body of which includes at least three mobile drive systems (5) which are actuated by electro-mechanical means and move in a synchronised concentric manner, approaching and moving away from the central point and acting on a rotating structure (41) from equidistant angles, said structure being centrally located and coupled in a detachable head (4) that is coupled centrally relative to, and above, a cylindrical tank (2). The drivers (5), provided with brushes (51), move from an open position in which they remain separate from one another and at a distance from the centre, into a closed position in which they are joined to one another in the centre of the tank (2), coming into contact with the structure (41) containing the parts to be treated. The structure (41), coupled to a casing (8), consists of a vertical rod provided with securing means (42) for the parts to be treated.
