Definitions

the invention relates to a straightening machine for aligning wire with a straightening set which comprises a plurality of straightening units which can be adjusted in their radial position relative to the longitudinal axis of the straightening set.
a straightening machine with adjustable straightening units is known from EP-A1-620-058.
the straightening set is formed by a rotor which can be rotated about its longitudinal axis by a rotary drive and which, as straightening units, comprises straightening nozzles through which the wire to be aligned is guided.
the directional nozzles are mounted so as to be radially displaceable and their position can be adjusted jointly via a displacement element which has inclined planes which act laterally on the holders of the directional nozzles.
the disadvantage of this device is that the rotor has a relatively high weight and thus a high moment of inertia when accelerating or braking, that the adjustment is relatively coarse and that an adjustment to the properties of the wire (for example its internal stresses depending on the type of manufacture) only is possible to a limited extent.
the straightening nozzles are individually manually adjusted, which of course involves a lot of work. It is therefore common to provide several rotors set to different wire diameters, which can be replaced if necessary.
a straightening machine is known from EP-A1-619 154, in which the straightening set is formed by a plurality of straightening rollers, of which every second straightening roller can be adjusted in its radial position via an adjusting knob. With this straightening machine, too, the changeover to a different wire diameter is labor-intensive.
the object of the invention is to provide a novel straightening machine, by means of which the disadvantages of the previously known straightening machines are overcome and which can be quickly and precisely reproducibly adjusted to different wire diameters.
this is achieved in a straightening machine of the type mentioned at the outset by the fact that the radial positions of individual straightening units of the straightening set can be adjusted remotely via the adjusting device, the adjusting device having at least one adjusting unit which is decoupled from a first passive position in which it is decoupled from the straightening units , can be transferred into a second active position in which it is in engagement with at least one straightening unit for adjusting the same.
the invention can be used in straightening machines with a roller straightening set, in which the straightening units are formed by rollers between which the wire is guided.
straightening nozzles through which the wire is guided are provided as straightening units. Because the actuating units are decoupled from the straightening units during operation of the straightening machines, the rotating mass can be kept low.
the straightening machine shown in FIGS. 1 to 3 has a rotor 2 which is rotatably mounted about the axis 1 and which contains the straightening units 3.
the rotor 2 is driven by a motor 6 via V-belts 4 and associated V-shafts 5.
the wire to be aligned is drawn off from a coil and along the rotor of the straightening machine guided. As a result, the aligned wire can be cut to a straight round steel rod.
the straightening set 7 comprises five straightening units 3 designed as straightening nozzles 8, which are fixed in the rotor 2 with respect to their axial position and radially, i.e. can be individually adjusted by an adjusting device 10 perpendicular to the longitudinal axis 1 of the straightening set 7.
the directional nozzle 8 has a nozzle plate 9 which contains the actual nozzle 11.
the nozzle plate 9 is slidably mounted in the nozzle frame 12 via guide strips 12a which engage in guide grooves of the nozzle plate 9.
the radial adjustment of the straightening nozzle 8 takes place via a spindle drive 13. This is formed by a hollow thread 9a contained in the nozzle plate 9 and an adjusting screw 14 mounted in the nozzle frame 12.
a latching device 15 (see FIG. 2) is provided, which has a latching ring 16 rigidly connected to the adjusting screw 14 and provided with radial bores and spring balls which are mounted in a bolt 17 and are under spring force includes, which can snap into the holes in the locking ring.
the locking device achieves a defined angular position of the adjusting screw 14.
a sealing sleeve 18 pinned to the adjusting screw 14 is provided in order to prevent the ingress of dirt.
the actuating device 10 comprises a plurality of actuating units 20 assigned to the straightening units 3, one actuating unit 20 being provided for each straightening unit 3.
the actuating units 20 are driven together via a chain 21, which is driven by an actuator motor 23 via a chain wheel 22.
the adjusting units 20 have adjusting shafts 24, the adjusting nuts 25 of which can be brought into engagement with the adjusting screws 14.
clamping couplings are provided which comprise wedge sleeves 27 driven by the chain 21 via chain wheels 26, in which the adjusting shafts 24, are designed as spline shafts are stored.
the adjusting shafts 24 are therefore mounted in the wedge sleeves 27 in a rotationally fixed manner but axially displaceable by pneumatic piston-cylinder units 28 and can move from the piston-cylinder units 28 from a first passive position into a second active position in which they are engaged with the respective adjusting screw. be transferred.
the setting of the actuating units is carried out by first bringing the rotor into the setting position in which the displacement axis 29 of the respective directional nozzle 8 coincides with the axis 30 of the actuating unit 20.
one of the adjusting shafts 24 is lowered into the active position by means of the piston-cylinder unit 28 until the adjusting nut 25 is seated on the adjusting screw 14.
the adjusting screw is now rotated by the desired angular range via the actuator motor 23.
a rotary encoder 31 can be provided for monitoring and recording the rotary movement of the adjusting screw 14.
a stepping motor can also be provided as the actuator motor 23, which can be rotated by a defined angular amount, so that in this case no rotary encoder is necessary. In this way, a defined position of the nozzle 11 can be approached and stored in an electronic memory of a control device.
the actuating shaft 24 is then retracted. The process can then be repeated for all straightening nozzles 8.
the setting process can be controlled by a user via a control panel.
a control device which automatically and automatically executes the entire setting process based on previously stored setting values.
An important advantage of the straightening machine according to the invention is that the rotating masses of the adjustable rotor are only slightly higher than in conventional rotors that cannot be adjusted remotely.
the rotor can also have straightening rollers instead of straightening nozzles over which the wire is guided.
the surface of such a straightening roller generally has a concave, approximately parabolic profile.
the straightening rollers can in turn be adjusted in their radial positions via spindle drives and an adjusting device is provided for individually adjusting the radial positions of the straightening rollers, which corresponds to that described above.
the idea according to the invention of providing an adjusting device for the remote-controlled or controlled adjustment of the radial bearings of the straightening units is not restricted to straightening machines with a rotor straightening set, but can also be used for straightening machines with a fixed roller straightening set, as shown in FIG. 4.
the actuating units 20 of the actuating device 10 are only individually assigned to the upper six rollers 40 here.
the lower five rollers 40 could also be individually adjustable.
the actuating device 10 in turn functions in exactly the same way as described above and a spindle drive can again be provided for the radial adjustment of the rollers 40.
two of the straightening sets shown in FIG. 4 are preferably used, which are perpendicular to one another and through which the wire passes in succession.
