Definitions

  • the invention relates to a device for pulling or braking metal strips or sheets, in particular narrow strips to be wound together on a winding shaft with band-wise separate braking action, preferably in band lines, between two oppositely arranged and driven by chain wheels, endless chain systems that rotate the band or sheet clamp with trolley-like roller blocks guided on strips in a straight driving area.
  • Such a brake stand for metal or sheet metal strips is known from DE-OS 32 08 158.
  • the large traction or retention force required when braking metal strips can be applied to the surface of the split or non-split strip without damaging effects, so that even very surface-sensitive strips, e.g. Aluminum tape, let it be treated.
  • the invention has for its object on the one hand to expand the possible uses of the known brake scaffold and on the other hand in particular to further stabilize the run-in and entrainment conditions when the carriage-like roller blocks enter the band-entrainment area.
  • this object is achieved by guiding each chain in a circular arc with the exception of the driving area over the entire course.
  • a chain arrangement encircling the circular and circular chain apart from the straight driving area, to which the inclined sections on the inlet and outlet sides of the otherwise straight strips are also to be counted, although there are essentially no supporting forces, the chains composed of a large number of roller blocks coupled directly to one another can be largely used redirection move freely so that on the one hand the targeted parallel feeding of the opposite roller blocks of the chain systems into the driving area is supported and on the other hand a much higher speed - for example up to 1,000 m / min. - can be reached.
  • each chain system has only one side, preferably on the belt pull side, which has chain wheels which are essential for the drive. It is then advisable to arrange circular deflection and guide segments at least on the outlet side of the belt facing away from the chain wheels, which support the chains on the outlet side.
  • This arrangement applies to generator, mirror image of motor drive.
  • the chain, with its sliding bushes or axles, therefore only dips once in each rotation into the one provided with semicircular divisions for engagement in the chain axles. Sprocket on, while the chains can roll on the opposite side without a jagged transition on the deflection and guide segments. The movements that are transferred from the sprockets to the chains and are inevitable due to the fact that they move in and out are reduced by half, thus increasing the service life of the chains.
  • the straight inner strips of the driving area lie opposite, circular arc-shaped guide strips which, on the one hand, seamlessly engage in deflection curves which are pivotably mounted on a drive shaft of the sprockets and are designed as tensioning segments, and on the other end at a distance from the outlet-side guide segments.
  • the chain With each parallel to the sprockets on the drive shaft-arranged tensioning segments, the chain can also be guided on the inlet side in such a way that its chain axes run as far as possible over the immersion points of the engagement divisions of the chain wheel, which reduces the effects on the chain. Immersion of the chain axles is to be expected in particular immediately after the vertical position of a semicircular division of the chain wheel on a radian of approximately 10 to 15 °.
  • Tensioning cylinders arranged in the frame can engage with the piston rods on the outer guide rails. This allows a leverage effect to be achieved on the sprocket shafts and the chains can be tensioned via the pivotable tensioning segments, so that the chain or drive shaft itself remains free of displacements, in particular the otherwise usual horizontal displacements.
  • the strips of the driving area preferably end on the pull side at a distance from the tensioning segments and engage seamlessly in the guide segments at the opposite end.
  • the deflection or guide segments on the belt outlet side are thus unaffected by adjustment movements.
  • the roller blocks can be put on, in particular taking into account the deformation of the elastic covering of the driving surfaces of the roller blocks that occurs when the tape comes into contact , evenly parallel. Feeding the top chain, for example, with a slope of a fraction of a degree, enables a specific load to be changed as required, exactly where the surface is shifted most due to the loads when it is put on; The greatest specific loads can also be brought about in this area.
  • the targeted, even placement of the roller blocks in the driving area can also be achieved by a different number of divisions of the chains, the lower chain being preferably extended by one division compared to the upper chain; this chain therefore runs on a larger orbit in order to match the other, upper chain in the driving area again and to use the entire driving or surface of the roller blocks in the pressing area.
  • roller block having side guide rollers
  • the chains can be kept exactly in their prescribed orbit, since the rollers can rest and be supported on the guide strips or segments.
  • the utilization of the entire surface of the roller blocks in the driving or pressing area can preferably be achieved with a width of the driving surfaces of the roller blocks corresponding to the chain pitch between the pivot points defined by axes of two adjacent blocks.
  • roller blocks with a variable number of support wheels more than the at least two wheels or rollers required can be used if loads such as the bending, the surface pressure, the shear and tensile strength and the torsion are to be expected, which the permissible values.
  • At least the tensioning segments can have an elastic coating, which also keeps the support and side guide rollers in better contact with the track.
  • the rollers press into the elastic coating, for example made of polyurethane, and are thus kept constantly at the rotational speed, which contributes to the high speeds and, in particular, does not require a renewed acceleration.
  • an elastic coating of the track is recommended wherever low support forces have to be absorbed; for high band tension to be applied, an uncoated steel raceway is recommended, especially in the driving area.
  • an elastic driving surface can be inserted into a lateral groove of the track so that it protrudes or protrudes and keeps the rollers at speed.
  • a measuring section can be arranged after the stand, preferably a stand with a chain system directly adjoining on the outlet side, on which the strip can be put down for inspection, or which otherwise runs continuously at the strip running speed .
  • a stretch with the belt can advantageously be used between the stand and a pipe drawing machine arrange rolls forming a tube.
  • the up to 200 t possible strip tension make the material flow even with thick strips.
  • the flow process can be used to form the strip, which is possible with low energy because of the flow state.
  • heat-conducting contact surfaces can be provided in the surfaces of the carriage-like roller blocks;
  • the elastic linings of the roller blocks can be exchanged for copper plates, which can transfer large amounts of heat to the belt in a very short time.
  • the current can be switched on specifically when the roller blocks pass through the driving area. This means that current is only supplied during the time that large pressure forces are present, so that arcs and thus burn marks on the strip surface are avoided.
  • a great advantage of this measure is that the heat supply can be switched off at any time.
  • an annealing furnace must be kept at a constant temperature even during the inevitable breaks in operation - such as on weekends, for example.
  • the brake and restraint scaffold 1 consists of two chain systems 3, 4, which are open at the top and which serve for better installation and removal, which are installed in windows 5 of the column 2 and of which the upper chain system 3 is by means of cylinder-actuated piston rods 6 against the lower chain system 4.
  • the chains 3, 4 are composed of a large number of coupled, carriage-like roller blocks 7, which extend over the entire width of a belt 9 arriving in the direction of the arrow 8 (FIG. 2) and roll on at least two support wheels 10 and side guide rollers 11 on a track or lie on the side.
  • the track is in a driving area 12, in which the opposite roller blocks 7 grasp the belt 9 on both sides and clamp between them, of straight strips 13 with bevels 14 on the inlet and outlet sides, of tension segments 15 on the inlet side and deflection and guide segments 16 on the outlet side and of that Driving area opposite, outer circular arc-shaped guide strips 17 are formed.
  • the tracks of the chains 3, 4 have at least an elastic coating 18 in the area of the clamping segments 15; in addition, the surfaces of the roller blocks 7 are also provided with an elastic coating 20.
  • the upper or driving surfaces of the roller blocks 7 are of a width corresponding to the chain pitch T and extend within the pivot points defined by the axes of the support wheels 10 of two adjacent, ie successive blocks.
  • the tensioning segments 15 of the chain systems 3 and 4 are pivotably arranged on the inlet side on a chain shaft 22 next to the chain wheels 23 driving the chains 3, 4.
  • the chain or drive shaft 22 is supported in a box frame 21 enclosed by the revolving chain system.
  • the outer guide strips 17 engage seamlessly in the tensioning segments 15 and are arranged in the upper and lower box frames 21
  • the torque / introduced into the chain shaft 22 by a drive is transmitted from the chain wheels 23 to the chain systems 3, 4, for which purpose the chain wheels 23 have a multiplicity of semicircular divisions 27 - the greater the number of divisions, the smaller the division error is - which engage in axes 28 of the roller blocks 7.
  • the chains 3, 4 roll on the deflection and guide segments 16 fixed on the support axles 29 of the box frame 21 without a drive.
  • the brake stand 1 described can - as shown in Fig. 3 - be used to form a tube 30 from the band 9.
  • the high band tension in the brake scaffold 1 causes the material to flow and enables the band 9 to be deformed without requiring a great deal of energy.
  • the braking and restraint scaffold 1 is followed on the outlet side by a molding-in section 31 comprising first a roller set 36, 37 and then at a distance from a vertical and a horizontal roller 32, 33, in which a first deflection of the belt 9 takes place.
  • a molding-in section 31 comprising first a roller set 36, 37 and then at a distance from a vertical and a horizontal roller 32, 33, in which a first deflection of the belt 9 takes place.
  • In the running direction at a distance behind it is a further group of rollers consisting of vertical and horizontal rollers 32, 33, which optionally enclose all sides, and which finally form the ribbon into tube 30.
  • a known pipe drawing machine 34 for further transport of the pipe 30, which encloses the pipe between circumferential clamping systems arranged opposite one another.
  • a known strip straightening machine 35 shown in FIG. 3 can be arranged immediately after the brake stand 1 and before the forming section 31.
