Definitions
- the invention relates to a straightening machine for aligning wire according to the preamble of claim 1 with a standard sentence, the several adjustable in their radial position relative to the longitudinal axis of the straightening set Straightening units included. (see e.g. EP-A-0 287 494).
- a straightening machine with adjustable straightening units is known from EP-A1-620-058 known.
- the straightening set is formed by a rotor, which consists of a rotary drive is rotatable about its longitudinal axis and the straightening nozzles as straightening units includes, through which the wire to be aligned is passed.
- the directional nozzles are radially displaceably mounted and they can in their position together via a sliding element can be set, which has inclined planes, the sides of the Attack holders of the straightening nozzles.
- the disadvantage of this device is that the rotor has a relatively high weight and thus has a high moment of inertia when accelerating or braking that the Adjustment is relatively rough and that an adjustment to the properties of the wire (e.g. its internal stresses depending on the type of manufacture) is only possible to a limited extent.
- the straightening nozzles are individually manual adjusted, which of course involves a lot of work. So you can see usually several rotors set to different wire diameters, which are exchanged if necessary.
- a straightening machine is known from EP-A1-619 154, with the straightening set of several Straightening rollers is formed, of which every second straightening roller in a its radial position is adjustable. The change is also in this straightener to another wire diameter 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 can be.
- 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 led.
- the straightening units are formed by rollers, between which the wire is led.
- the straightening units are as straightening units
- Directional nozzles are provided through which the wire is guided.
- the straightening machine shown in FIGS. 1 to 3 has a rotatable around the axis 1 mounted rotor 2, which contains the straightening units 3.
- the rotor 2 is via V-belts 4 and associated spline shafts 5 driven by a motor 6.
- the one to align Wire is drawn from a coil and along the rotor of the straightening machine guided. As a result, the aligned wire can become a straight round steel bar be cut to length.
- the straightening set 7 comprises five straightening nozzles 8
- Straightening units 3 which are fixed in terms of their axial position in the rotor 2 and radial, i.e. perpendicular to the longitudinal axis 1 of the straightening set 7 from an adjusting device 10 are individually adjustable.
- the directional nozzle 8 has a nozzle plate 9 which contains the actual nozzle 11.
- the Nozzle plate 9 is in the nozzle frame 12 via guide strips 12a, which are in guide grooves the nozzle plate 9 engage, slidably mounted.
- the radial setting of the Straightening nozzle 8 takes place via a spindle drive 13. This is driven by one in the nozzle plate 9 contained hollow thread 9a and an adjusting screw mounted in the nozzle frame 12 14 formed.
- a locking device 15 (see Fig. 2) is provided, which one with the Adjustment screw 14 rigidly connected and provided with radial holes Locking ring 16 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.
- Locking ring 16 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.
- Anti-rotation is a defined angular position of the locking device Adjustment screw 14 reached.
- Sealing sleeve 18 is provided to prevent the ingress of dirt.
- the adjusting device 10 comprises several adjusting units assigned to the straightening units 3 20, an adjusting unit 20 being provided for each straightening unit 3.
- the Actuators 20 are driven together via a chain 21, which via a Sprocket 22 is driven by an actuator motor 23.
- the actuating units 20 have adjusting shafts 24, the adjusting nuts 25 of which with the adjusting screws 14 can be brought into engagement.
- Clamping couplings are provided on the actuating shafts 24, which extend from the chain 21
- Sprockets 26 include driven splines 27 in which the actuating shafts 24, are designed as spline shafts are stored.
- the adjusting shafts 24 are in the wedge sleeves 27 therefore non-rotatably but axially of pneumatic piston-cylinder units 28 slidably supported and can of the piston-cylinder units 28 by one first passive position into a second active position, in which they correspond with the respective Adjusting screw are engaged, are transferred.
- the setting of the actuators is now done by first turning the rotor into the Setting position in which the displacement axis 29 of the respective directional nozzle 8 with the Axis 30 of the actuator 20 covers, is brought.
- one of the control shafts 24 lowered by means of the piston-cylinder unit 28 into the active position until the Adjusting nut 25 sits on the adjusting screw 14.
- About the actuator motor 23 is now the adjusting screw is rotated by the desired angular range. It can Monitoring and recording the rotary movement of the adjusting screw 14 an encoder 31 may be provided.
- a stepper motor can also be used as the actuator motor 23 be provided, which can be rotated by a defined angular amount, so that in this case no encoder is necessary. In this way, a defined position the nozzle 11 are started and in an electronic memory of a control device can be saved.
- the actuating shaft 24 is then retracted. The process can then be repeated for all straightening nozzles 8.
- a user can control the setting process via a control panel be made. But it is also possible to provide a control device which the entire setting process based on previously stored setting values executes automatically and automatically.
- 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 conventional ones rotors that cannot be remotely controlled.
- the rotor can also have straightening rollers as straightening units instead of straightening nozzles, over which the wire is passed.
- the surface of such a straightening roll shows in generally a concave, roughly parabolic profile.
- the judging roles are again in their radial positions adjustable via spindle drives and individual Adjustment of the radial positions of the straightening rollers is provided by an adjusting device corresponds to that previously described.
- an actuating device for remote-controlled or controlled Adjustment of the radial bearings of the straightening units is not necessary Straighteners with a rotor straightening set limited, but also with straighteners applicable with a fixed roller straightening set, as shown in Fig. 4.
- the Actuating units 20 of the adjusting device 10 are only individual for the upper six rollers 40 here assigned.
- the lower five rollers 40 could also be individually adjusted be trained.
- the actuator 10 in turn works on exactly that same way as described above and for the radial adjustment of the rollers 40 can again a spindle drive can be provided.
