(54) | Method for bending metal profiles in bar form and machine for performing the method |
(57) The method for bending metal profiles in bar form is performed in a machine comprising
a line (3) for feeding the profiles in the form of bars to be bent, along which there
are devices (4) for driving the bars, a cropping assembly (5) and at least one bending
assembly (6). The method entails: processing the end portion of the bars by performing
the advancement of the end portion of the bars by virtue of the driving devices (4);
and stopping the end portion of the bars in a preset position. The end portion of
the bars is gripped by virtue of an extraction assembly (8) provided with a clamp-type
grip device (9) suitable to be actuated with a reciprocating motion. The end portion
of the bars is then subjected to a translational motion, for an advancement stroke
of controlled extent, to complete the dimensions of the shaped articles to be provided,
then the shaped articles are cropped to size. |
