Definitions

  • the invention relates to a device for pulling or braking metal strips, in particular narrow strips to be wound together, with band-wise separate braking action, preferably in band lines, between two sprockets that are endlessly rotating and can be pressed against one another, and are articulated from one another, in pairs above and below the metal band arranged links existing, the metal band between clamping chain systems.
  • Metal strip is preferably moved in strip treatment plants with drivers or pull and brake roller systems.
  • the necessary strip tension is generated in such a plant in addition to drivers and reels, especially with pull and brake roller systems.
  • the rollers are driven and more or less wrapped around the belt.
  • the strip hoists can only be set up or taken down from roll to roll within very specific limits.
  • the belt deflections require additional drive power and are undesirable for metallurgical and technological reasons.
  • the roller diameters are chosen so that parts of the belt are plastically deformed even with small belt thicknesses.
  • a device of the type mentioned has become known from AT-A-295 974.
  • the difficulties encountered when winding sheet metal strips, in particular sheet metal strips cut into longitudinal strips, onto a reel core are eliminated there by combining a friction brake with a brake generator.
  • the inclusion of a friction brake in the braking device should make it possible to compensate for the speed differences between the individual strip strips by means of sliding friction, i.e. to apply the braking force, the force of the brake generator is supported by the frictional force caused by the sliding friction of the friction brake.
  • the sliding friction occurs when it is possible to slide the brake bands, which are not driven but are carried along by the continuous sheet metal strip, relative to the sheet metal strip.
  • This known braking device therefore presupposes the generation and exploitation of relative movements as functionally decisive.
  • pressure rollers acting on their plate members are arranged to press against each other.
  • These pressure rollers are based on the principle of a stringing together of drivers known in strip treatment plants and used for moving metal strip; apart from the distribution of the loads on a number of pressure points corresponding to the number of driver rollers arranged opposite one another, this pressure roller arrangement does not differ from the known drivers.
  • this pressure roller arrangement does not differ from the known drivers.
  • a device in which a metal band is clamped between two driven, endlessly rotating friction systems.
  • two belts arranged opposite one another in a machine frame and deflected by guide and drive rollers are provided, which hold the metal strip between them.
  • the upper belt is set against the opposite, lower belt by means of a hydraulic cylinder.
  • the hydraulic cylinder engages a support frame which receives the drive rollers and is resiliently supported by springs and connected to a pressure plate which lies against the belt from above; the pressure plate supporting the opposite belt, however, is not adjustable.
  • the chain pulling and braking device can be used in particular as a brake scaffold in splitting systems.
  • a known retaining device (DE-PS 1804 178) consists of several rings which are rotatably arranged under friction on a shaft upstream of the reel.
  • the braking torque can be adjusted to a maximum belt tension by means of an axially supplied pressure medium, the braking torque being transmitted to the flanks of the ring hubs by means of friction disks that are inserted between the rings. If higher stresses occur, the corresponding rings perform compensating rotary movements relative to the shaft and to the other rings.
  • the invention has for its object to avoid the aforementioned disadvantages and to provide a simple and reliable device for keeping the tension constant for slit strips and unsplit strips, without the need for an additional preferred device.
  • the elaborate control driver can be omitted, since the rectangular entry of the strip is achieved by the twisting movement of the chain pulling and braking device.
  • the links have coatings, preferably an elastic covering, which can advantageously be equipped with a profile.
  • the coatings the elasticity of which can be influenced by the thickness, the profiling and the degree of hardness, a high coefficient of friction can be achieved between the links and the metal strip; on the other hand, due to the support of the links via rollers or sliding surfaces, there is a low coefficient of friction with the guide strips.
  • the support rollers are fed to the support area via a run-up curve, so that the respective chain segment is smoothly taken over.
  • the chain brake device is preferably adjusted in slit systems according to the lowest strip speed.
  • the strip strips with the faster strip speeds have an advance in the contact area of the chain brake device.
  • the associated different lengths of the slit band are compensated for by the elasticity of the covering, which is initially compressed and allows resilience in the area of the respective advance.
  • the specific tension in the strip cross-section changes only insignificantly, since the pressure forces can be distributed over a relatively large area.
  • the narrow-band slit strips can be wound up with uniform tension regardless of thickness differences.
  • the pulling or braking forces can be regulated continuously over a wide range using the contact pressure of the chain systems.
  • the transferable forces can be significantly increased by using additional chain wheels or support structures within the chain systems.
  • the chain pulling and braking device can still be used wherever the so-called S-roller units are used in belt treatment lines.
  • Stretch-bending straightening units are provided with up to 5 S-rolls in front of and behind the bending stand so that the necessary strip tension can be applied. It is expedient to equip each individual S-roll with egg 1 em separate GS drive positioned.- in a mechanical coupling with a GS-Ausretesanvieb. This is necessary because, due to the manufacturing tolerances and the uneven wear of the S-roll coatings, 3 relative speeds are avoided have to. This leads to a considerable expenditure of mechanical and electrical equipment as well as a large space requirement. When using the chain pulling and braking device proposed by me, only one scaffold in front of and behind the stretch-bending straightening unit is necessary. Only two GS drives are required.
  • a special embodiment of the chain pulling and braking device provides that the rectangular entry of the belt into the device is achieved by means of a pivoting movement in the belt passage plane. This process can be automated.
  • the chain pulling and braking device is arranged in front of the take-up reel, it is a special embodiment that the device is adjusted according to the continuously changing entry angle of the incoming strip. This arrangement has the advantage that the tape retraction is applied immediately before the take-up reel.
  • the chain pulling and braking device is used in a gap line as a brake stand, the narrow belts would be fed from a splitting shear, not shown, via a loop storage device with a deflection roller and then through the chain brake device via a further deflection roller to the take-up reel.
  • the actual chain brake device remains unchanged in all gap programs
  • the chain system is preferably operated by a direct current motor with a comb gear connected downstream.
  • the braking torques are passed on via the shaft 2 to the chain wheels 3 and to the chain segments.
  • the support rollers 5 transmit the torques once and support the segments 4 in the driving area via guide strips 6a with support curves 6 in the inlet and outlet and brace the belt 1 by chain segments 4 lying opposite each other over the segment coating 7, which as an elastic covering 11 with a profile 12 can be executed.
  • the lower chain system 4b is fixed, while the upper chain system 4a is adjustable.
  • the contact forces are adjustable.
  • the chains are pretensioned by means of cylinder 8, which displaces a guided bearing housing 9.
  • the oscillating rotating brush 10 removes all possible contaminations and buildup on the contact surfaces.
  • a special application provides that the fixed chain system is designed as a rocker construction 13. This ensures that the chain pulling and braking device can be tilted to a certain angle in accordance with the incoming belt.
  • the control frame 14 has the task, if the band does not run at 90 ° on the segments 4, to turn the entire chain pulling and braking device in the band plane until the right-angled band entry is restored. Automatic control is state of the art.
