Definitions

  • the present invention concerns a method and an apparatus for making stirrups, in particular tridimensional stirrups.
  • EP 0519865 discloses a tridimensional apparatus which allows to make stirrups of considerable size. Nevertheless, such solution does not well suit to the use in the field of metal rods for reinforced concrete, furthermore it results to be very complicated and expensive to produce.
  • EP 0396489 discloses a supplementary fold device suitable for apparatuses intended for the field of metal rods for reinforced concrete. Such device is able to create folds in a metal wire on different planes with respect to the work plane, allowing in this way the shaping of tridimensional stirrups in an easy way.
  • WO 2011/064222 discloses an apparatus for making tridimensional stirrups comprising a first fold unit provided with first contrasting means, a support rotatable with respect to the first contrasting means and first bending means mounted mobile around said first contrasting means. The first bending means are predisposed to cooperate with the first contrasting means in order to bend elongated metal elements on a first bending plane defined by said support.
  • the apparatus further comprises a second fold unit comprising second contrasting means mounted on said first bending means and second bending means arranged mobile with respect to the support in a slanting direction with respect to the first bending plane.
  • Known solutions of this type comprise two clearly distinct fold units, operatively aligned along the rod feeding axis, which, therefore, do not allow to easily make structures of reduced size.
  • the presence of two fold units besides burdening on the apparatus costs, may also be an obstacle to the working of bidimensional stirrups.
  • the two fold units are arranged reciprocally spaced from one another at a certain distance, penalizing nevertheless the production of tridimensional elements which often require the alternation of folding phases between the two fold units and the transfer from one unit to another till the product is complete.
  • the task of the present invention is that of solving the aforementioned problems, devising a method and an apparatus which allow to make in an optimal manner both bidimensional and tridimensional stirrups.
  • Another scope of the present invention is that of providing an apparatus for making tridimensional stirrups having a simple conception, a securely reliable functioning and versatile use, as well as relatively economic costs.
  • the method for making stirrups provides to prearrange at least one handling unit for a metal rod feeding and/or backing according to a handling direction, a fold unit provided with a central folding mandrel and with an eccentric fold pin rotatable about a central mandrel for folding the same metal rod.
  • the fold unit works on a work plane represented by the geometrical plane orthogonal to the central mandrel axis and comprising the above mentioned handling direction.
  • a grip means mobile transversally to the work plane is provided so as to intercept the metal rod to be folded, the grip means being as well rotatable about the axis of the intercepted metal rod in order to rotate the same intercepted metal rod and perform the folding by means of said fold unit for making a tridimensional stirrup.
  • the method provides then to handle the metal rod along the handling direction by means of the above mentioned handling unit; performing the folding of the metal rod on the above mentioned work plane by means of the fold unit, by operating in rotation the eccentric folding pin about the central mandrel in suitable step relationship.
  • the method provides as well, in suitable step relationship with the cited handling and with folding steps, to operate the grip means in a direction transversal to the work plane for intercepting and tightening the rod.
  • the grip means when the rod is tightened by the grip means, the other members which are in contact with the rod release it.
  • the grip means rotates about the axis of the tightened rod, in a controlled way, thus producing the corresponding rotation of the same rod.
  • the axial rotation of the rod, tightened by the grip means, enables the fold unit to make a tridimensional stirrup.
  • the method provides to perform a sequence of folding steps of the rod by means of the same fold unit suitable to perform such folding steps on the same work plane, which orientation is fixed.
  • the rotation of the metal rod performed by the grip means occurs in controlled way, so as to ensure the making of the tridimensional stirrup according to the desired design.
  • the rod is free as much as possible, that is, being gripped merely by the grip means, at least for a considerable tract, so as to avoid or minimize twisting stress.
  • the apparatus comprises, in a corresponding way, a fold unit, working in an operative station for the tridimensional folding of a metal rod on a respective work plane.
  • the apparatus comprises a handling unit for handling and leading the rod to the fold unit, feeding and/or backing, and grip means mobile transversally to the cited work plane and rotatable about the handled rod, for intercepting, tightening and rotating the same rod about the same direction.
  • the rotation of the grip means mobile on the work plane and substantially rotatable about the handling direction of the rod, allows to perform a series of folds for making tridimensional stirrups, starting from a handled metal rod, feeding and/or backing, along the above mentioned handling direction.
  • the handling unit can be alternatively operated between an active configuration, gripping the rod to be handled, and an inactive configuration, releasing the same rod.
  • the grip means can be made up of one or more jaw clamps, foldaway mobile transversally to the work plane.
  • the above mentioned jaw clamps can be interposed between the handling unit and the fold unit for intercepting an intermediate portion of the metal rod to be worked.
  • the apparatus comprises a cutting and measuring station and transferring means from the cutting and measuring station to the operative station wherein the cited fold means, the grip means and the feed means are provided.
  • the operative station for the bidimensional and tridimensional folding of the metal rod can be placed on a different level, preferably parallel and overlaying with respect to the cutting and measuring station, in which the rod is firstly drawn and then possibly straightened.
  • the operative station for the bidimensional and tridimensional folding of the rod can be placed on the same plane of the drawing and measuring station.
  • the cited transferring means performs the transferring of the rod by shifting on the same work plane.
  • a main drawing unit is preferably present, and the cited external handling unit is associated with it, opposed with respect to the fold unit.
  • the handling unit for the tridimensional folding can coincide with the main drawing unit.
  • the above described transferring means cannot be provided, since the feeding and cutting steps occur on the previously described work plane, on which the fold unit and the handling unit are suitable to cooperate.

  • the drawing wheels 4 can be arranged on the work plane 2, coplanar, so as to shape between them, at the handling direction A, a passage channel 8 for the rod 3. More precisely, the drawing wheels 4 can be operated, in each couple, alternatively between an inactive configuration and an active configuration. In the inactive configuration, the opposite wheels 4 are arranged separated from each other, for widening the passage channel 8 so as to receive the rod 3 to be handled towards the fold unit 5.
  • the drawing wheels 4 are approached to each other for tightening the rod 3 prearranged in the passage channel 8.
  • a respective command means is prearranged for mutually approaching and spacing the drawing wheels 4 of each couple, synchronically, and for driving in rotation at least one wheel of each couple.

More precisely, for “backing” it is meant the displacement along the handling direction A, oriented from the handling or drawing unit 4 towards the fold unit 5.
