Definitions

  • the invention relates to a spring manufacturing machine with a machine frame on which a wire feed and a wire guide for feeding a wire in a feed direction, further downstream of the wire guide, perpendicular to the supplied wire in both the height direction and in the direction perpendicular to the machine frame movable dome and according to this a parallel to the wire feed direction as well as in two mutually and in each case to the wire feed direction movable directions movable forming tool are mounted.
  • the machines with 2-finger system are in turn suitable only for the production of pure coil springs without angled legs, since the wire always remains positioned after a single start in the wire guide grooves of the wind finger.
  • 2-finger system larger quantities and more accurate spring geometries than with the 1-finger system can be produced.
  • the US 1 882 243 A describes an apparatus for forming and bending workpieces of flexible material.
  • a rotary mandrel having a wire guide channel, which is formed in the dome at a distance from one side wall and through which the supplied elongated workpiece is passed, wherein it is insertable via an opening of the dome in the wire guide channel.
  • the dome is made very solid and allows only a bending of the workpiece around itself.
  • the present invention seeks to improve a spring coiling machine, which is normally suitable only in the 2-finger system for producing pure coil springs (compression springs), so that they are also used for the production of simple leg springs in 1-finger system can.
  • the mandrel has a wire guide channel which is formed in the dome at a distance from the machine frame facing away from the outer side wall, through which the supplied wire is passed through the mandrel to the forming tool and that the mandrel further comprises an opening for inserting the wire into the wire guiding channel.
  • the mandrel in a direction perpendicular to the wire feed direction plane both in the top-bottom, as well as in the front-back direction, and by the use of a movable in two mutually and in each case to the wire feed direction movable forming tool (“3D -Windefinger ”) is in addition to the winds and the bending of the wire in any direction (top-bottom, front-back) feasible.
  • 3D -Windefinger a movable in two mutually and in each case to the wire feed direction movable forming tool
  • a conventional spring coiling machine which operates on the 2-finger system, can be easily converted to the 1-finger system.
  • the exchange of the forming unit, the dome unit and possibly the cutting blade and the wire guide can increase the overall product range producible on the machine quite considerably.
  • the economic benefits achieved by the invention are particularly remarkable.
  • the wire guide channel is most preferably formed in the form of a guide groove, which, again preferably, has a groove depth which corresponds at least to the diameter of the supplied wire, so that it does not protrude from it as it passes through the guide groove.
  • This offers the possibility of executing the wire feed channel also with a closed cross-section, which can be opened to form the opening for inserting the wire in a suitable manner.
  • the wire guide channel in the form of a guide groove with a non-closed, but unilaterally open cross-section formed, it is particularly advantageous if the guide groove on its side facing away from the machine frame side legs extending from one end perpendicular to the longitudinal center plane of the wire guide channel and parallel to the wire feed direction plane boundary wall is connected to the outer side wall of the dome, wherein preferably this planar boundary wall, perpendicular to the wire feed direction, has a width which is greater than the wire diameter.
  • a further advantageous embodiment of the invention also consists in that the opening for inserting the wire into the wire guide channel runs directly next to the boundary wall and extends over the entire length of the mandrel in the wire feed direction.
  • this opening has an opening perpendicular to the plane boundary wall, which corresponds to the wire diameter or slightly larger than this, so that from the outside easy passage of the wire through the opening and its insertion into the wire guide channel is easily possible.
  • the wire guide channel is formed as a guide, whose configuration so made that the longitudinal center plane of the guide extends perpendicular to the flat boundary wall.
  • the dome is constructed in two parts and includes an upper and a lower dome portion. Both dome sections for creating the opening for inserting the wire into the wire guide channel are preferred from a closed position in which the wire guide channel formed in one of the two dome sections and completely open to the interface between both dome sections is completely covered and closed by the other dome section opened position in which the wire guide channel is opened and the opening for inserting the wire is formed in it between the two Domabitesen.
  • a preferred embodiment is also the two dome sections about a common hinge pivot each other and form scissor-shaped hinged, so that the creation of the opening for insertion (or lead out of the wire), the two Domabitese can be opened and thus the desired access to the wire guide channel is created. After the insertion or removal of the wire, however, the two Domabschhitte be closed again and thus again achieved a closed wire guide channel.
  • a further preferred embodiment of the spring manufacturing machine according to the invention also consists in that the dome additionally a circular arc-shaped bending surface is formed to the bending system of the supplied wire whose axis of curvature is perpendicular to the feed direction of the wire, wherein, preferably, the bending surface in a direction perpendicular to the longitudinal center plane of the wire guide channel attached to the cathedral.
  • the bending axis of the bending surface is advantageously placed so that it is either perpendicular or parallel to the longitudinal center plane of the wire guide channel.
  • a very particularly preferred embodiment of the invention consists in the fact that in two-part design of the mandrel, when both parts from a closed to an open position (and vice versa) can be brought, the depth of the guide is chosen slightly smaller than the diameter of the wire and also the cathedral comprising the two dome sections can also be moved in the feed direction of the wire (and in the opposite direction).
  • the dome can also be used as a gripper for the wire at the same time, which is held jammed in the closed position of both Domabête between them.

FIGS. 9 and 10 ) is withdrawn from the wire intake 4 via one or more pairs rotatably driven feed rollers 11 from a wire supply, not shown, straightened in the straightening unit 3 by a plurality of straightening rollers and supplied by the feed rollers 11 downstream wire guide 5 of the forming unit 7 in Drahtzutechnischides s.
  • the pitch device 8 is known per se; it makes it possible to generate a correspondingly desired pitch between the individual turns of the spring by moving outward (perpendicular to the wire axis and perpendicularly away from the machine frame 2 to the front).
  • the mode of action and the use of such inclining devices is known to the person skilled in the art, so that it is not necessary to discuss them further here.
  • each forming slide 13 is equipped at its front end with a forming tool 15, while in the in Fig. 1 shown, converted to 1-finger system spring manufacturing machine 1 only at the lower Umformschieber 13 a forming tool 15 is mounted on an adapter plate 22.
  • the forming tool is a 3D wind finger 23 (also called a "leg spring device " ), which serves as the forming unit 7 here.
  • the 3D Windefinger 23 has on its the dome unit 6 end face facing a guide groove 28 for receiving, guiding and deflection of the wire 10 (see. FIGS. 9 and 10 ).
  • the (upper) Umformschieber 13 of the 2-finger system which is not required for 1-finger conversion, is removed during the conversion to the 1-finger system or moved to a retracted position in which it remains.
  • the forming mandrel 16 is fastened in a dome box 17 (compare the enlarged detail of the forming area in FIG Fig. 2 ), which in turn is slidably inserted into a Domschlitten 18.
  • the Domschlitten 18 is vertically (perpendicular to the wire 10) in the w- direction movable, so that the Umformdom 16 can always be positioned directly on the already wound wire.
  • the dome box 17 in turn can be moved in the x- direction to and from the rear (also perpendicular to the wire 10), both traversing directions in Fig. 2 indicated by arrows.
  • a knife 21 for separating a spring produced (if it is worked in the 2-finger system) is provided.
  • a knife 21 is used only at the upper cutting gate 20, which is designed so that it separates the wire directly at the outlet 25 of the wire guide 5 (see Fig. 3 ).
