Abstract: A drawing assembly for drawing machines for metal products (B) comprises two tracks (11) opposite each other and counter-rotating that collaborate with said metal products (B) on opposite sides with respect to a drawing axis (X) to draw them along said drawing axis (X) The tracks (11) are disposed in a closed ring around respective support plates (13), and an intermediate chain (15) is interposed between the track (11) and the corresponding support plate (13). Each support plate (13) includes at least two guide segments (18; 118), lateral, having a convex shape externally mating with the curve of the intermediate chain (15). The drawing assembly (10) comprises, for each intermediate chain (15), an automatic tensioning device (21) provided with at least one thruster member (22) acting on a respective one of the guide segments (18; 118) in order to exert constantly upon it a distancing thrust, to keep it constantly in contact with the corresponding intermediate chain (15).

Abstract: A bar unloading apparatus of the revolver type, comprising: —a longitudinal rotor (10) divided into at least three longitudinal stretches (11, 12, 13) integral with one another and adapted to rotate about a longitudinal rotation axis, on the outer longitudinal surfaces of which there is provided a plurality of longitudinal channels, extending on the at least three stretches over the whole longitudinal extension of the rotor (10) and parallel to said longitudinal axis, to receive respective longitudinal bars, —and at least one braking device for braking the longitudinal bars entering in at least one of the longitudinal channels, wherein the at least one braking device is integrated in at least one first stretch (12) of said at least three longitudinal stretches (11, 12, 13), is rotationally fixed to the longitudinal rotor (10) and is provided with braking elements (1) in each of said longitudinal channels so that said at least one braking device can rotate together with the longitudinal rotor (10) and brake th

Abstract: A drawing assembly for drawing machines for metal products includes drawing clamps, each selectively clampable in a housing seating of a corresponding link of a track, and on a corresponding lying plane, by a corresponding rapid attachment/detachment device associated with the link. The rapid attachment/detachment device includes at least a clamping element and an activation element, wherein the clamping element includes at least a segment having a cam profile able to cooperate with a mating cam surface of the activation element. The activation element is mobile in a direction of thrust, orthogonal to the median axis of the clamping element, and slides in a hollow with the mating cam surface in contact with the cam profile of the clamping element.

Abstract: An intermediate chain for drawing assemblies of drawing machines provided with at least one track having a plurality of contiguous links configured to act on a product being worked in order to draw it, is interposed between the corresponding track and support means of the track and comprises a plurality of contiguous links. Each of said links comprises an idle roll equipped with a through axial hole, a join pin and a connection element provided with a plurality of through holes configured to house at least said join pin. The connection element comprises two lateral support portions positioned in correspondence to axially opposite longitudinal ends of said idle roll, and a central connection portion, interposed transversely between the two lateral support portions and joined to both in order to reciprocally connect them, keeping them at a fixed and constant reciprocal distance and in a fixed and constant reciprocal position.

Abstract: A drawing assembly for drawing machines for metal products (B) comprises drawing clamps (16), each selectively clampable in a housing seating (17) of a corresponding link (12) of a track (11), and on a corresponding lying plane (P), by means of corresponding rapid attachment/detachment means (19) associated with the link (12). These comprise at least a clamping element (20) and an activation element (21), wherein the clamping element (20) comprises at least a segment (38) having a cam profile (30) able to cooperate with a mating cam surface (34) of the activation element (21). The activation element (21) is mobile in a direction of thrust (S), orthogonal to the median axis (Z) of the clamping element (20), and slides in a hollow (29) of the latter with said cam surface (34) in contact with the cam profile (30) of the clamping element (20).
