Abstract
Apparatus (10) for working oblong metal products (P), comprising a drawing unit (11) for moving at least one of said metal products (P) in a direction of feed (Z), and a work unit (12) disposed downstream of said drawing unit (11), comprising a work plane (13) with which at least one bending device (14) and at least one cutting device (15) are associated. The present invention also concerns a corresponding method to work said metal products (P).
Claims14
An apparatus configured for working oblong metal products to obtain finished products, the apparatus comprising:
- a drawing unit configured to move a metal product (P) in a direction of feed (Z);
- and
- a work unit disposed downstream of said drawing unit, said work unit comprising a work plane with which a bending device and a cutting device are associated;
- wherein said drawing unit is mobile in the direction of feed (Z) toward and away from said work unit, and said work unit is mobile in an operating direction (T) that is transverse to said direction of feed (Z);
- and
- wherein the cutting device is offset from the bending device in the operating direction (T), such that movement of the work unit in the operating direction (T) enables alignment of either the bending device or, alternatively, the cutting device with the direction of feed (Z) without simultaneous alignment of both the bending device and the cutting device with the direction of feed (Z).
A method of working oblong metal products (P) t comprising:
- providing an apparatus comprising:
- a drawing unit configured to move at least one of said metal products (P) in a direction of feed (Z), said drawing unit comprising dragging members provided with respective tracks;
- and
- a work unit disposed downstream of said drawing unit, said work unit comprising a work plane with which a bending device and a cutting device are associated;
- wherein said drawing unit is mobile in a direction of feed (Z) toward/away from said work unit, and said work unit is mobile in an operating direction (T) that is transverse to said direction of feed (Z);
- and
- wherein the cutting device is offset from the bending device in the operating direction (T), such that movement of the work unit in the operating direction (T) enables alignment of either the bending device, or alternatively, the cutting device with the direction of feed (Z), without simultaneous alignment of both the bending device and the cutting device with the direction of feed (Z);
- in a first step, moving the drawing unit backward in the direction of feed (Z), away from said work unit, and picking up by the drawing unit of at least one waiting metal product (P);
- in a second step advancing said drawing unit in the direction of feed (Z) toward said work unit to reach a work position where said at least one metal product (P) can be worked, and moving said work unit in said operating direction (T) so that said bending device is aligned with said at least one metal product (P);
- in a third step, while the drawing unit, remains stationary in the work position, advancing said at least one metal product (P) by said drawing unit by means of said dragging members toward said bending device, and performing by the bending device of workings to produce at least one first finished product;
- and
- in a fourth step, moving said work unit in said operating direction (T) so that said cutting device is aligned with said at least one metal product (P), and cutting and partly moving said at least one first finished product away from said at least one metal product (P).
