Drawing assembly for drawing machines

A drawing assembly for drawing machines for metal products, comprising:

• drawing clamps, each selectively clampable in a housing seating of a corresponding link of a track, by means of corresponding rapid attachment/detachment device said rapid attachment/detachment device comprising at least a clamping element and an activation element, said clamping element comprising a cam profile able to cooperate with a mating cam surface of a guide portion of the activation element, and said activation element being mobile in a direction of thrust, substantially orthogonal to a longitudinal axis of said clamping element, between a first position, in which said clamping element is in an active position and clamps one of said drawing clamps to a corresponding link, and a second position, in which said clamping element is in an inactive position and frees said clamp from the link, and wherein said cam profile of the clamping element comprises a flat support wall angled with respect to said direction of thrust and said mating cam surface of the activation element comprises a sliding flat wall, also angled with respect to said direction of thrust and substantially parallel to said sliding flat wall, wherein said clamping element comprises a hollow inside which said guide portion of the activation element slides in a guided manner, with said sliding flat wall in contact at a top with said flat support wall of the clamping element,
• wherein said hollow is defined by said flat support wall and by a mating inclined wall, positioned on opposite sides of said hollow and joined by a bottom wall, transverse to them both, and
• wherein said mating inclined wall is essentially parallel to said flat support wall.
