Abstract
The device can be applied to compression machines including a turret (1), rotating around a vertical axis and fitted with a series of die holes (3) aimed at being filled with powder of granular material; pairs of punches (5,6), upper and lower punches respectively, related to each die hole (3) and guided slidably in the turret (1), engage the die holes (3) with respective counterfacing working heads (5a,6a). The device features a driving cam (9) that drives at least one of the punches (5,6) and determines the reciprocal distance between the working heads (5a,6a) of each pair of punches, in the material batching step and in the material loading step; the driving cam (9) moves axially with respect to the turret (1) so as to adjust this distance. Further cams (11,12) are provided for completion of guiding structure (15) with variable profile, which facilitates entering in the driving cam (9). The cams (11,12) are mechanically linked to each other, so as to change the profile in accordance with adjusting position of the driving cam (9).
