Definitions

  • the invention relates to a system for processing, such as descaling, embossing and / or drawing, and subsequent straightening of wire with a decoiler, a processing device, in particular a descaling, embossing or drawing device, and a straightening and cutting device in which the wire feed direction In front of and behind the straightening rotor of the straightening device, pairs of drive rollers which detect the wire to be straightened with a clamping connection and a spill downstream of the processing device are arranged in front of the drive rollers.
  • This system structure makes it possible to pull the wire through the processing device with much greater tensile force by means of the motor-driven spill, which is wrapped around the wire several times, than would be possible by means of the driving rollers of the straightening device, which work approximately with point contact and with a clamping connection and therefore tend to slip.
  • a disadvantage of this type of plant is the high outlay which is caused by the separate drive motors for the spill downstream of the wire processing device and for the drive rollers assigned to the straightening device, and by the control devices for these motors.
  • the resulting wire winding is then usually stored temporarily until it is straightened in a straightening device immediately before it is further processed and cut to pieces of the desired length in a cutting device downstream of the straightening device.
  • This procedure is labor-intensive and also harbors the risk that a new dirt and oxide layer forms on the newly cleaned wire surface during the intermediate storage, which is detrimental to further processing, in particular a welding process.
  • the invention is now concerned with the task of designing a wire processing system of the type specified in the introduction in such a way that the wire can be pulled through the processing device with high tensile force without the previously required high outlay on separate drive motors for the capstan and the drive roller pairs of the straightening device and associated control devices must be accepted.
  • This object is achieved in such a way that the capstan and the rollers of the drive roller pairs can be driven by a common motor with different peripheral speeds, the peripheral speed of the rollers of the drive roller pairs being greater than the peripheral speed of the capstan, and that devices for pressing the rollers of the Driving roller pairs with selectable pressure on the wire are provided.
  • the high tractive force required behind the processing device is secured by the motor-driven spill, which is wrapped in several wire windings, whereas the drive roller pairs driven by the same motor with somewhat greater circumferential speed and tending to slip only have a smaller one, of which they are easily selected accordingly Must generate clamping force to be applied.
  • a wire processing system is known from DE-A1-2 651 812 in which the wire is to be continuously given a torsion or twist size by means of a rotating cold-forming head.
  • a disk which is wrapped around it several times and from which the rotary drive for the cold-forming head is derived.
  • This disk itself is not driven by a motor, but is only carried along by the wire drawn through the rotating cold-forming head by means of the drive rollers of a subsequent straightening device.
  • the disc mentioned does not act as a capstan and therefore does not lead to a relief, but rather to an additional load on the drive rollers of the straightening device, which also exert the necessary tensile force for the wire to be passed through the cold-forming head.
  • a wire 1 is drawn off a reel 2 and passed through an emergency shutdown device 3 known per se. This serves to shut down the entire facility add if, for example, the wire drawn off the reel forms a loop which should lead to a wire break when passing through the subsequent device.
  • an emergency shutdown device 3 known per se. This serves to shut down the entire facility add if, for example, the wire drawn off the reel forms a loop which should lead to a wire break when passing through the subsequent device.
  • a descaling device with a crushing descaling section 4 and a brush descaling section 5 and finally a straightening device 6 with scissors 7. All of the devices mentioned in the system are known per se in various designs.
  • a motor 10 is provided in the straightening and cutting device 6, which on the one hand drives a capstan 13 via an intermediate gear 11 and a worm gear 12, around which the wire 1 is guided in one or more turns, and on the other hand Via a V-belt drive 14 drives pairs of drive rollers 15, 16 which move the wire through the straightening device 6.
  • the transmission ratios of the gears 12 and 14 are coordinated with one another in such a way that the peripheral speed of the capstan 13 is slightly less than the peripheral speed of the drive roller pairs 15, 16.
  • the drive rollers of the drive roller pairs 15, 16 can be adjusted by suitable devices, for example pressure springs 17 and screw spindles 18, with respect to the contact pressure they exert on the wire.
  • suitable devices for example pressure springs 17 and screw spindles 18, with respect to the contact pressure they exert on the wire.
  • the contact pressure of the drive rollers on the wire 1 is dimensioned such that the tensile force exerted by the drive rollers on the wire 1 becomes sufficiently large so that the frictional force acting between the wire 1 and the capstan 13, on the one hand, ensures that the wire 1 is pushed forward without slippage ensured by the descaling device, but on the other hand, a slip is possible between the drive rollers and the wire 1 in order to take into account the different peripheral speeds of the capstan and the drive rollers.
  • the traction rollers which turn a little faster than the wire feed speed, exert a uniform tensile force on the wire. As a result, the frictional force between the wire and the circumference of the spill remains constant, which ensures a constant feed speed of the wire.
  • the straightening rotor 20 is also driven by the motor 10 via a V-belt drive 21.
  • scissors 22 and an outlet path 23 are provided after the straightening device, into which the straightened wire is conveyed.
  • the scissors which are also driven by the motor 10 via transmission elements, which are not shown because they are not essential to the invention and are known, are activated and separate a piece of the desired type Length from the descaled and straightened wire.
