Abstract
In an apparatus for cold bending a metal sheet for making an elongated article with a predetermined pro-file, supports are provided to receive opposite ends of the sheet being formed. A form, whose cross section defines a predetermined profile, is operated perpendicularly with respect to its longitudinal axis, so as to clamp the sheet, resting on the supports, to a stop. Bending members are carried by two plates which are mounted for oscillating on a vertical plane transversal to the form, so that the bending members rotate around spindles parallel to the stop plate. The bending members are operated in time relation with a synchronous movement of the form and of the stop, so as to fold the two ends of the sheet piece over the form.
Claims7
An apparatus for cold bending a metal sheet to obtain an elongated article having a predetermined section profile, said apparatus comprising:
- support means for supporting opposite ends of the sheet to be formed;
- a form having a longitudinal axis and a section shaped according to said predetermined profile, said form operated perpendicularly with respect to the longitudinal axis;
- a stop that faces said form, so that said form, when lowered, clamps said sheet resting on said support means to said stop;
- two plates mounted for oscillation on a vertical plane transverse to said form;
- two spindles fitted to said plates and arranged parallel to said form and located at either side of said stop plate;
- two bending members rotatable about said spindles, means for driving said bending members in time relation with a synchronous movement of said form and said stop, such that the bending members fold the two ends of said sheet around said form.
