Definitions
- the invention relates to a device for pulling or braking metal strips, in particular narrow strips to be wound together, with strip-wise separate braking action, preferably in strip lines between two oppositely arranged, endlessly rotating and mutually compressible clamping elements.
- Metal strip is preferably moved in strip treatment plants with drivers or pull and brake roller systems.
- the necessary belt tension is generated in such a system in addition to drivers and reels, especially with tension 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 roll diameters are chosen so that parts of the strip are plastically deformed even with small strip thicknesses.
- 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. Tensioning occurs when one belt is turned against the other belt by means of a hydraulic cylinder.
- the chain pulling and braking device can be used in particular as a brake scaffold in splitting systems.
- a known retaining device (DE-PS 1 804178) 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 which 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 split strips and unsplit strips, without the need for an additional preferred device.
- the object is achieved in that the metal strip is clamped in parallel between two circulating chain systems and each chain system circulating by means of chains and sprockets has a plurality of chain segments placed one behind the other and arranged opposite one another in pairs above and below the metal strip and which can be pressed against the metal strip. Has friction elements.
- the support segments are guided coaxially to the belt, lie opposite one another in pairs, the contact surfaces with the metal belt receive a high coefficient of friction and with the support surface a low coefficient of friction or rolling support, and due to the profile and the degree of hardness Coating and its thickness, the elasticity can be metered.
- 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 in Spaltanla gene preferably adjusted 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 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 advisable to equip each individual S-roll with a separate GS drive or, in the case of mechanical coupling, with a GS compensating drive. This is necessary because, due to the manufacturing tolerances and the uneven wear of the S-roll coatings, relative speeds have to be avoided. 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 band into the device is achieved by means of a pivoting movement in the band pass 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 contamination and buildup on the contact surfaces.
- a special application form provides that the fixed chain system is designed as a swing arm construction 13. This ensures that the chain pulling and braking device can be inclined to a certain angle in accordance with the incoming belt.
- the control frame 14 has the task, if the tape does not run at 90 ° on the segments 4, to rotate the entire chain pulling and braking device in the tape plane until the right-angled tape inlet is restored. Automatic control is state of the art.
