Definitions

  • the present invention relates to a wire transport assembly, which has been specifically designed for application to wire bending and winding machines.
  • the wire which is entrained by transport rollers towards the forming center, is bent by one or more bending slides which are mounted on the frontal plane or panel of the machine.
  • the wire is bent by tools which are mounted on the bending slides.
  • the wire entraining rollers including one or more pair of rollers, are motor driven and possibly controlled by an electronic control unit, and are fixedly mounted on the wire processing machines.
  • a first type is provided with a wire feeding parallel to the front portion of the machine, whereas the other is provided with a wire feeding at 90° with respect to the machine processing plane, depending on the different type of processing to be performed.
  • the aim of the present invention is to overcome the above mentioned drawbacks, by providing a wire transport assembly, specifically designed for wire bending and winding machines, which allows to include therein the typical features of the two above mentioned prior machines thereby providing the possibility of performing two different types of wire feedings, depending on the different processes to be performed.
  • a main object of the present invention is to provide such a wire transport assembly which allows to change the configuration of the wire processing machine in a very quick and simple manner.
  • Another object of the present invention is to provide a wire transport assembly which, owing to its constructional features, is very reliable and safe in operation.
  • Yet another object of the present invention is to provide such a wire transport assembly for wire bending and winding machines which can be easily made starting from easily available elements and materials and which, moreover, is very competitive from a mere economic standpoint.
  • a wire transport assembly specifically designed for wire bending and winding machines, comprising, on a machine frame, a wire guiding assembly for feeding said wire towards a bending or winding center, characterized as set forth in the characterizing portion of claim 1.
  • the wire transport assembly specifically designed for wire bending and winding machines, according to the present invention, comprises a machine, generally indicated at the reference number 1, which includes a bearing frame 2 defining at the front thereof a plane or bearing surface 3 or panel therein are provided working or processing assemblies which consist, preferably, though not exclusively, of one or more wire bending slides mounted on said bearing surface or panel.
  • the main feature of the invention is that there is provided a wire guiding assembly 10, including one or more pairs of electronically controlled motor driven rollers 11, said wire guiding assembly 10 being arranged so as to be able of turning through 90° about an axis which is substantially perpendicular to the axis of the wire 20 being fed or supplied.
  • a single machine which can fed or supply the wire either parallel to the bearing surface of the machine, in the case in which this machine is to be used as a wire winding machine, or a wire bending or eyelet forming machine, or, as shown in Figure 2, perpendicularly to the laying plane of the machine, in the case in which the machine is to be used as a conventional spring forming machine.
  • the wire 20, in particular, can be fed or withdrawn with a very great accuracy, through the wire guiding assembly which, as disclosed in a previous patent application of the same Applicant (Italian patent application MI92A 000988) which is included herein by reference, can turn about the axis of the wire; accordingly it is possible to combine two movements, that is the rotation of the wire guiding assembly about a perpendicular axis in order to perform a double location with a double use of the machine, and the rotation of the wire guiding assembly about the axis of the wire.
  • a wire transport assembly which allows to include in a single machine two functions, which are at present made by two different machines, by simply providing a wire guiding assembly adapted to be rotated through 90° about an axis perpendicular to the axis of the wire, so as to provide, on the same machine, both a wire feeding perpendicular to the working plane of the machine, and a wire feeding turned through 90°, in parallel to the working plane.
