DEVICE FOR BURNISHING AND SMOOTHING METAL PARTS

Abstract

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 electromechanical 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.

PREFERRED EMBODIMENT OF THE INVENTION

[0026] In light of the above mentioned figures and according to the adopted numbering, it can be appreciated that in them one can see the preferred embodiment, but not limitative of the described device for burnishing and polishing of metallic pieces, which comprises parts and elements which are described and indicated in detail as follows.

[0027] Such as can be seen in the figures, the device (1) in question, applicable to electrolytic processes for polishing and cleaning of jewelry pieces, is configured essentially from a tank (2) into which an electrolytic solution is introduced with a main body (3) which is coupled centrally and on its upper portion to an extractable head (4) which serves as a support element for the frame (41) unto which the pieces to be treated (not included in the figures) are placed, such that upon coupling it over the main body (3) of the tank (2) they are submerged in the solution. Additionally, said main body (3) contains three mobile propelling systems (5) which are activated by electromechanical means provided for this purpose on said main body, present an approach and retreating concentric displacement movement from the central point, acting from equidistant angles on the frame (41), and thus on the metallic pieces which are incorporated within it.

[0028] In the preferred embodiment of the device (1), the tank (2) is cylindrical and the main body (3), also having a circular plan, consists with a fastening disk (6) unto which some guides (7) are coupled radially, on which the propelling systems (5) are run, tracing the described approaching and retreating concentric synchronized movement from an open position (FIGS. 4-A and 5-A) on which they remain separated from each other and away from the center, to a closed position (FIGS. 4-A and 4-B) in which they join with each other at the center of the tank (2) coming in contact with the frame (41).

[0029] As FIG. 3 shows, the propelling systems (5) have a vertical structure which comprises some brushes (51) made from a soft material, suitable for acting on the pieces without damaging them, and a support (52) unto which the sheets (51) are fixed and which, in turn, is coupled by means of a platen (53) to which the guides (7) are screwed unto on its upper portion.

[0030] Meanwhile, the frame (41), which as previously highlighted, is coupled on its lower part unto an extractable head (4) which is coupled to the main body through a central orifice provided thereof and which also is incorporated in the tank (2), consists with, at least, one vertical rod, conveniently provided along the length of the same with fastening means (42), clearly visible in FIG. 2; rod which is coupled on its upper end to a shell (8) provided for this purpose on the lower central part of the frame (41).

[0031] This frame (41) preferably, presents a rotational movement, driven by electromagnetic means provided on the head in such a way that, at least one rod which constitutes it, with the pieces to be treated, turns at the center of the tank (2) at the same time that it is attacked by the action of the concentric movement of the propelling systems (5).

[0032] Having described the nature of present invention sufficiently, as well as having undertaken its practice, it is considered that it is not necessary to further explain it in order for a person skilled in the art to understand its scope and the advantages it provides, noting that within its essence, other undertakings of it which could differ in their detail from that of the example title of the invention could be carried out, all of which would attain equally the protection sought, as long as its fundamental principle is not altered, changed or modified.
