Definitions

  • the present invention relates to a wire guide for bending and twisting machines, including improved wire engagement means.
  • the aim of the present invention is to overcome the above mentioned problems, by providing a wire guide for wire bending and twisting machines, which is so designed and arranged to greatly simplify the construction of the machine.
  • a main object of the present invention is to provide such a wire guide which, by causing the wire or the machine bars to advance and turn about an axis thereof, provides the possibility of easily performing all of the desired bends or curved patterns.
  • Yet another object of the present invention is to provide such a wire guide which is very reliable and safe in operation, can be easily made starting from easily available elements and materials, and which, moreover, is very competitive from a mere economic standpoint.
  • a wire guide for wire bending and twisting machines including improved wire engagement means, characterized in that said wire guide comprises a wire guide body, rotatively supported so as to rotate about an axis thereof, and wire locking means, operating on said wire guide body or immediately near said wire guide body.
  • the wire guide for wire bending and twisting machines which has been generally indicated by the reference number 1, comprises a supporting element 2 for supporting a rotatable wire guide 3, which is arranged axially of the body 2.
  • a hardened head 4 of the rotatable output wire guide 3 To the body 2 is coupled a hardened head 4 of the rotatable output wire guide 3; the wire guide 3 is coupled to a supporting flange 10, which is also designed for rotating, on ball bearing 11.
  • a fixed wire guide 20 On the extension of the rotatable wire guide 3 is provided a fixed wire guide 20, arranged at wire entraining or driving rollers 21.
  • the main feature of the invention is that, in a rotatable wire guide body 3, are provided wire locking means, which are directly coupled to said wire guide, or are supported immediately near the wire guide, so as to allow to properly lock the wire and to cause it to turn by exploiting the rotary movement of the rotatable wire guide.
  • the wire driving rollers will be closed, and the wire guide will rotate about the wire.
  • the possibility of turning the wire for a set angle and to return again to the starting position allows to greatly simplify the bending equipment and to reduce to a minimum the number of bending units included therein, in particular as the pieces to be made are of complex shape.
  • a locking assembly which comprises a locking cylinder 30, operating on a lever 31 pivoted at one end thereof, and counter-urged by a return spring 32, to cause the lever to return to an unlocking position.
  • a wire guide has been provided which is very simple construction-wise, and is specifically designed for exploiting the rotatable wire guide body, in combination with wire locking means, to perform the desired rotary movement of the wire, which will simplify a lot of working operations.
  • the used materials, as well as the contingent size and shapes can be any, depending on requirements.
