Definitions

  • the invention relates to a straightening device for rotating straightening of wire, in which a plurality of straightening devices, each having a directional nozzle are provided on a base for passing the wire to be straightened, comprising an inlet part and an outlet part and between these at least one rotating straightening unit, wherein the Directional nozzles of the inlet and outlet part are arranged centrically, while the directional nozzle of the at least one rotating straightening unit is seated eccentrically in a rotational body rotatable about the central axis thereof.
  • straightening wire for wire processing machines is to bend the wire in all planes to reduce or balance its residual stresses, which is ultimately reflected in as straight a wire as possible.
  • the inlet part and the outlet part are formed as a turntable and have a sprocket into which a pinion engages.
  • the turntables thereby rotate about an axis, with different directional nozzles can be brought into a working position.
  • a middle part which is arranged between inlet part and outlet part and which comprises a plurality of rotating straightening units, can likewise be rotated about an axis in such a way that different directional nozzles, each mounted in a rotatable rotary body, can be brought into a desired working position.
  • Each rotary body is driven by a belt drive by a motor, whereby the respective located in the working position of the center nozzle can rotate around the wire at a certain speed.
  • the radial position of the directional nozzle to the axis of rotation of the rotor is effected via an axially hydraulically adjustable, wedge-shaped part, which cooperates with a contact roller, the radial deflection of the mean directional nozzle causes (upon counteracting a spring preload on this) with axial displacement of the wedge-shaped part.
  • this known straightening is of a relatively complicated overall structure, which allows only a change in the eccentricity of the directional nozzle of the middle straightening unit, but not other directional nozzles. If changes in the axial distances of the directional nozzles relative to each other are desired, the corresponding changes require considerable manual intervention. The assembly of this straightening mechanism is complicated, so that even if any malfunction occurs (such as due to material fracture o. ⁇ .) Extensive repair work may be required.
  • the present invention seeks to propose a straightening, which is particularly simple and quick to assemble and in which changes and / or additions of the straightening structure are simple and quick to execute.
  • a straightening device of the aforementioned type which has a modular structure of individual mounting modules.
  • each preferably comprises a mounting module, the inlet part or the outlet part or at least one straightening unit with a rotating body bearing bearing housing and / or a motor for driving this rotating body or a rotating body of another mounting module, further comprising all mounting modules on the basis of the straightening separately fastened are.
  • the straightener according to the invention creates due to its modular design of individual units the possibility for a particularly quick and easy assembly, with later changes without difficulty quickly and inexpensively and are very variable feasible.
  • the individual bearing solution achieved in the invention as a result of the mounting modules shows (compared to a solution with directional wings) a lower imbalance because of other tools and because of the saved directional wing.
  • directional wings must be replaced frequently, since the threads for the pressure screws for fixing the straightening jaws wear out quite quickly.
  • the modular design creates the possibility to build the straightening systems according to the invention in a kind of modular system of prefabricated units, which are designed as mounting modules units basically for different straightening can be used, so that each straightener can be constructed from such standardized basic units.
  • the modular structure of the straightening invention allows a rapid change by inserting or removing individual mounting modules, this change also requires only a relatively small downtime of the respective straightening , Since the modular structure of the straightening mechanism according to the invention also allows good accessibility to each rotating straightening unit with its respective directional nozzle, even a replacement of a directional nozzle in a straightening unit can be carried out quickly.
  • the individual straightening units used in the invention in the individual assembly modules can achieve a symmetrical bearing load, since the rotational body can be driven via a centrally arranged belt. In addition, they provide better accessibility to the straightening process: the adjustability of the assembly modules and these straightening units allows a much easier threading of the wire and a better visibility of the actual investment behavior of the wire to the directional nozzles.
  • the assembly modules of a straightening mechanism according to the invention which can be fastened on a base thereof separately from each other, can also be adjusted quickly in their respective position individually.
  • a particularly preferred embodiment of the invention consists in the fact that the mounting modules on the basis of the straightening mechanism are all parallel to each other and each perpendicular to the axis of rotation of the rotary body of the respective mounting module adjustable.
  • Another preferred embodiment of the straightener according to the invention also consists in that the mounting modules as well as the inlet part and the outlet part in the conveying direction of the wire (axially) are adjustable relative to each other.
  • the mounting modules as well as the inlet part and the outlet part in the conveying direction of the wire are adjustable relative to each other.
  • an adjustment of this straightening parameter possibly in conjunction with a further adjustment perpendicular to the wire conveying direction, both during operation of the straightener, which results in a great flexibility for the inventive straightening.
  • the axial adjustment of the assembly modules or their straightening units allows a very sensitive adjustment for the straightening process.
  • a very particularly preferred embodiment of the straightening mechanism according to the invention also consists in that all the individual parts comprising a single mounting module are mounted on a common base plate or base of this mounting module, which, mounted for mounting this mounting module, only at the base of the straightening itself becomes.
  • a particularly advantageous embodiment of the straightener according to the invention can also be achieved in that all mounting modules, except with an inlet part or a spout part, always next to a rotating body and a directional bearing bearing housing also have a motor for driving the rotating body, so that each such Mounting module includes in itself a rotating straightening unit including the associated drive and thus already self-sufficient ensures a full function of the rotating straightening unit.
  • the storage is also simplified and cheaper in such an embodiment in addition, since then no assembly modules with rotating bodies without associated drive must be kept.
  • the individual assembly modules can initially be prepared for the assembly of the straightening mechanism according to the invention at the mounting location and then assembled to the finished straightening. Most preferably, however, all mounting modules are already designed as prefabricated units so that they can already be delivered to the assembly site and installed there immediately.
  • each rotational body is preferably provided for passing through its directional nozzle with a radially extending slot in which the respective directional nozzle spent in the desired radial position and then there is correspondingly positionally blocked.
  • a further preferred embodiment of the invention is that the directional nozzle in its eccentric position on the rotational body of its associated straightening unit by a on this fixed bracket can be fixed.
  • this holder is particularly preferably formed from two attached to the two axial end sides of the rotary body cover plates, each having an opening for holding the directional nozzle on both sides of the rotary body.
  • the directional nozzle can be aligned radially in these two openings on the rotating body and fixed therein.
  • the two lateral cover plates are each provided with a plurality of openings which are provided in different eccentricity to the central axis of the associated rotational body, wherein in each case an opening in the one cover plate of an opening in the other cover plate is provided accordingly.
  • each rotating body is provided with a radially extending slot
  • each cover plate is designed as a cover strip which is adjustable parallel to the slot in the rotation body for adjusting the eccentricity of the directional nozzle. Even so, it is possible to achieve a rapidly feasible and continuous adjustment of the eccentricity of the directional nozzle on the rotary body.
  • the modular construction used in a straightening device according to the invention makes it possible in principle for such a straightening device to be able to displace the individual assembly modules in their relative position relative to each other, perpendicular and / or parallel to the conveying direction of the wire Changes in the straightening parameters can be accommodated, and this also during operation of the straightener, without this would have to be brought to a standstill.
