Definitions

  • the present invention relates to a wire guide for bending and twisting machines, including improved wire engagement means (see for example US-A-5 170 654).
  • 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.
  • the above mentioned aim and objects are achieved by a wire guide for wire bending and twisting machines according to claim 1.
  • Claims 2-4 describe further embodiments of the invention.
  • 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.

Claims (4)

  1. Eine Drahtführung (1) für Drahtbiege- und -verwindungsmaschinen, wobei diese Drahtführung (1) einen Drahtführungskörper (3) umfaßt, der drehbar getragen wird, so daß er um eine Achse von einer Startposition aus drehen kann, sowie eine Drahtbefestigung (30, 31, 32), die auf diesen Drahtführungskörper oder unmittelbar neben diesem Drahtführungskörper (3) wirkt, dadurch gekennzeichnet, daß dieser Drahtführungskörper von einem Tragflansch (10) gehalten wird, der drehbar auf einem Kugellager (11) ruht, wobei auf einer Verlängerung dieses drehbaren Drahtführungskörpers (3) eine in der Nähe von Drahtführungswalzen (21) befindliche, befestigte Drahtführung (20) bereitgestellt ist, daß eine Stellvorrichtung bereitgestellt ist, die eingeschaltet wird, um diese Drahtbefestigung zu betätigen und somit diesen Draht zu befestigen und ihn um einen voreingestellten Winkel drehen zu lassen, indem die Drehbewegung dieses drehbaren Drahtführungskörpers (3) ausgenutzt wird, während gleichzeitig die Öffnung dieser Drahtführungswalzen (21) veranlaßt wird, und daß beim Ausschalten dieser Stellvorrichtung diese Drahtbefestigung (30, 31, 32) von diesem Draht gelöst wird, während diese Drahtführungswalzen (21) erneut geschlossen werden und es diesem Drahtführungskörper (3) gestattet wird, erneut zu dieser seinen Ausgangsstellung zurückzukehren.
  2. Eine Drahtführung nach Anspruch 1, dadurch gekennzeichnet, daß diese Drahtbefestigung mit dem Drahtführungskörper (3) verbunden ist.
  3. Eine Drahtführung nach einem oder mehreren der vorhergehenden Ansprüche, dadurch gekennzeichnet, daß diese Drahtbefestigung einen Schließzylinder (30) umfaßt, der auf einen Befestigungshebel (31) wirkt, der den Draht erfassen kann und gegen den eine Rückholfeder (32) drückt.
  4. Eine Drahtführung nach einem oder mehreren der vorhergehenden Ansprüche, dadurch gekennzeichnet, daß diese Drahtbefestigung konische Blöcke umfaßt, die im Drahtführungskörper (3) am Drahteinlaß angeordnet und dazu angepaßt sind, als Spannfutter geschlossen zu werden.
