Definitions

  • the invention relates to a scaffold for pulling or braking metal strips or sheets, in particular for a plurality of narrow strips to be wound up together with band-wise separate braking action, between two opposing endless chain systems driven by chain wheels.
  • Such a brake stand for metal or sheet metal strips is known from EP-PS 195 096.
  • the chain systems of which clamp the strip or sheet metal with carriage-like roller blocks guided on strips in a straight driving area the great pulling or restraining force (up to 200 t) required when braking or pulling metal strips can be done without damaging the surface of the split or non-split tape.
  • This is primarily achieved by the targeted feeding of the chain systems with the roller blocks into a relatively short clamping and driving area by means of straight guide rails, which at the same time enable the large clamping forces to be supported.
  • each chain supports the targeted feeding of the roller blocks.
  • the chains which are composed of a large number of directly coupled roller blocks, can then be moved largely without deflection, 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, very high speeds - e.g. up to 1000 m / min - are possible .
  • a braking device known from AT-B 383 754, strand-shaped bodies are driven between oppositely arranged, endlessly rotating ones Trigger bands clamped.
  • Trigger bands clamped.
  • cleat chains are pressed onto the trigger belts and thus the strand-like body to be braked by means of slide skid rockers acted upon by pressure cylinders.
  • the train is applied via the deflection rollers driving the pulling belts by means of frictional engagement; the belt tension to be achieved with this is only very small.
  • the invention has for its object to avoid the above disadvantages and to prevent dirt particles from entering the chain case.
  • this object is achieved in that a belt is arranged between at least one chain system and the metal strip.
  • Such the chain systems in a straight line Driving area shielding straps could be unwound, for example, from supply rolls arranged on the inlet side of the stand and wound onto winding rolls arranged on the outlet side of the stand.
  • the belt or belts is or are taken along in the driving area by the circulating chain systems.
  • the belt is designed as an endless belt radially enveloping the chain system.
  • the chain systems which are preferably both radially enveloped by an endless belt, are thus protected by a closed surface, so that scale, such as from strongly scaled hot strip, zinc and tin abrasion or other dirt particles can no longer enter the chain case; Downtimes due to contamination are therefore largely excluded.
  • the closed surface of the endless belts also allows the belts to be cleaned on the inlet or outlet side of the entrainment area by means of steam jets, which is an additional advantage, in particular when processing highly surface-sensitive belts.
  • the forces can be introduced via a linear motor instead of by means of a rotating motor (eg direct current motor) in the case of the chain systems shielded or covered according to the invention.
  • a rotating motor eg direct current motor
  • the metal strip can be displaced and different strip tensions can be achieved across the width of the metal strip.
  • the tax effect can influence the rolling process and the metal strip can be moved in the nip of the rolling mill rolls of a rolling stand.
  • the control effect during stretch straightening can be used as an additional manipulated variable; for example, the bending rolls of the stretch bending judge can also be steered like a control roll.
  • the belts or endless belts are not driven, but are taken along by the circulating chain systems in the driving or tensioning area of the scaffolding. Carrying the endless belts is ensured by contact with the coated, carriage-like roller blocks.
  • the forces acting on the endless belts, which result from the tensioning forces of the chain systems, the belt tensioning forces and, if applicable, lateral forces from the belt control, are safely transmitted; this can be done by choosing the material pairing of the contact surfaces, such as the material of the coating of the roller blocks and the endless belt, e.g. Rubber on rubber, are favored.
  • the specific loads on the belt can be kept very low.
  • the material of the belts for example polyurethane or rubber
  • the material of the belts for example polyurethane or rubber
  • An elastic coating of the roller blocks - depending on the purpose of the scaffold - could possibly be dispensed with entirely.
  • the pulleys support the easy winding of the endless belts from the long side; the belts can be slid onto the pulleys like loops.
  • a tensioning roller can also be arranged so as to be immersed in the endless belt - the endless belt to be pushed on or removed can be brought into a tensioned position required for operation or in a relaxed state which facilitates removal. Due to the simple exchange, it is easy to adapt the brake scaffold to tasks that have to be performed particularly, for example if the same scaffold is used to treat oiled tape instead of the previously processed dry tape.
  • the deflection rollers arranged on the inlet and outlet sides of the driving area be cylindrical.
  • the guiding of the endless belts directly in front of and behind the driving area via cylindrical rollers helps to prevent possible wrinkling in this area, which clamps the belt with extremely high forces without relative movement.
  • an automatic center setting of the circumferential endless belts can be achieved.
  • at least one of these rollers can be operated as a control roller, for example manually adjusted via a pivot point, and also influence the running of the endless belts in this way.
  • a scaffold comprising chain belts encased by endless belts can also be used as a squeezing unit and can be used, for example, in a pickling line as a drive, control and squeezing unit.
  • the effects or advantages described above can also be achieved if the sides of the straps facing the metal strip are provided with an elastic, preferably profiled, coating.
  • a polyurethane or rubber coating for example approximately 30 mm thick, in combination with the profiling, there is the possibility of achieving targeted elastic behavior, such as in particular when treating split strips.
  • the belt may be made of a heat-resistant, a heat-conductive or a noise-absorbing material or a combination of these (and other materials).
  • the nature and properties of the belt which is preferably made up of several layers of material, can be varied as required by suitable material selection depending on the operating conditions and intended use. With belts made of an asbestos-like, heat-resistant material, adaptation to hot metal strips can be achieved and a metal strip with high temperatures, for example up to 350 ° C., can be easily pulled or braked.
  • the belt which may consist of metal, metal alloys, fabric, polyurethane and rubber, for example, it may be multilayered, e.g. achieve cooling of the metal band due to a temperature gradient between the metal band and the belt; targeted cooling of the metal strip is therefore possible.
  • the heat dissipation from the belt depends on the thermal conductivity of the material for the belt; e.g. Made of a copper alloy, metal strips with temperatures up to 700 ° C, for example, can be metallurgically influenced. When a very hot metal strip cools down at a high cooling rate, certain microstructures can be achieved.
  • the scaffolding according to the invention for pulling or braking metal strips thus makes it possible to produce strip tension, at the same time to enable control effects and to exert metallurgical influence on the structure of the metal strip.
  • the belts can be designed for the transmission of current. If, for example, the straps have an outer coating made of copper, it is possible to transfer larger amounts of heat to the metal strip in the driving area of the scaffolding in a very short time; This is favored by the fact that, due to the metal strip gripped from two sides, large contact surfaces and thus large cross sections and high contact forces are available. With belts that have a rubber layer, the necessary insulation can also be easily achieved.
  • the noise reduction achieved anyway due to the covering or at least shielding of the chain systems can be further improved if the belts are made of a noise-damping material, e.g. made of rubber or rubber combined with a backing layer made of a textile fabric.
  • a noise-damping material e.g. made of rubber or rubber combined with a backing layer made of a textile fabric.
  • the brake and restraint scaffold 1 consists of two oppositely arranged chain systems 2, 3, of which the upper chain system 2 can be adjusted against the lower chain system 3.
  • the chains 2, 3 are composed of a large number of coupled, carriage-like roller blocks 4, which extend over the entire width of a metal strip 6 entering in the direction of the arrow 5 and with at least two support wheels 7 on a raceway 9 which is circular in shape except for the straight driving area 8 put this.
  • the raceway 9 is formed in its driving area 8, in which the opposite roller blocks 4 grip the belt 6 on both sides and clamp between them (see FIG. 2), of straight strips 10 with bevels 11 on the inlet and outlet sides.
  • the upper or driving surfaces of the roller blocks 4 are provided with an elastic coating 12; they have a width corresponding to the chain pitch and extend within the rotational positions defined by axes of the support wheels 7 of two adjacent, ie successive blocks 4 (cf. FIG. 2).
  • each chain system 2, 3 is radially enveloped by an endless belt 13.
  • the endless belts 13 are guided over deflection rollers 14, 15, 16 and 17, of which the deflection rollers 14 and 17 arranged on the inlet and outlet side of the driving area 8 are cylindrical.
  • those removed from the driving area 8, i.e. each have radially outer deflection rollers 15, 16 spherical, which favors the central guidance and / or adjustment of the guidance of the endless belts 13.
  • the endless belt 13 shown in cross section in FIG. 3 is constructed like a sandwich; it consists of three material layers 18, 19, 20, namely, for example, a backing layer 19 made of textile fabric, an inner layer 18 made of metal and an elastic outer layer 20 made of rubber or which comes into contact with the metal strip 6 (see the lower endless belt in FIG. 2) Polyurethane.
  • this structure merely represents a selection of any material layers for a sandwich-like endless belt that can be variably adapted and modified for the intended use.
