Definitions

  • Working process for the further processing of rolled rod material including profiles and adjusting device for carrying out the working process
  • the invention relates to a working method for the further processing of rolled rod material including profiles following a cooling bed, from which the rod material is laterally discharged in groups of cooling bed lengths onto a roller table, then straightened and fed for cutting to commercial lengths, collecting, stacking and binding, and an adjustment device for carrying out the working process.
  • the finishing in rolling mills with high production output means in many respects a bottleneck that forces the rolling stock to be fed through mechanical movements of the same type, which must then be at least twice as many. That is why the double-sided cooling bed with high-speed rolling mills is used with double run-out roller tables, scissors, straightening machines, collecting beds and stacking systems. Since the double-sided cooling bed causes material movement problems, it is known to use a single-sided cooling bed with only one discharge roller table because of the bottleneck when dividing the groups of cooling bed lengths discharged laterally from the cooling bed from this discharge roller table to alternately distribute the bar material laterally onto roller tables in groups (DE -OS.23 50 525). However, double the number of scissors and straighteners must still be provided.
  • Another proposal aims to continuously carry out the entire production in the finishing of a fine steel rolling mill with correct goods by stacking, tying and dividing the cooling bed lengths as a coherent unit after straightening.
  • dividing into commercial lengths is recommended as the last processing step in order to deal with the short cycle time as the main difficulty that results from dividing the groups of bars before stacking or collecting.
  • saws for dividing the stacked and. bundled cooling bed lengths are used, which means a high level of noise pollution, especially since it still has to be scooped (DE-OS 21 14 185).
  • the multi-core straightening with the optimal straightening speed quickly clears the roller table's downward roller table to accommodate a new group of rod material.
  • the subdivision of the bar groups in the flying cut under the feed of the multi-core straightening machine not only saves space for an otherwise required free runout but also maintains the continuous flow within the finishing line.
  • the pulling apart of the subdivided groups of rods by means of a feed speed that is higher than the directional speed makes it possible to lift the subdivided rod groups out of their direction of advance and to brake them down to the rest position.
  • a continuous adjustment device for carrying out the working process which is further developed on the basis of DE-PS 12 17 747 and which comprises a discharge device for rod groups in the area of the roller table's discharge roller table and a multi-wire straightening machine arranged directly behind the cooling bed is in claims 2 and 3 indicated and shown in the drawing in one embodiment.
  • the top view according to FIG. 1 shows the end of a cooling bed 1 with the discharge roller table 2, onto which the cooled rolling rods in cooling bed lengths are transferred to a discharge device 3 in rod groups intermittently.
  • a pair of driving rollers 4 and a multi-core straightening machine 5 are connected to the roller table 2.
  • a flying shear 6 for continuous Liche working arranged, which can be moved back and forth on a bed 7 in the feed direction.
  • the scissors (not shown in more detail) is a so-called guillotine scissors with knives which move in a straight line relative to one another, of which the upper knife is expediently driven by a drive motor 8 via a countershaft 9 and a cardan shaft 10.
  • the cutting knives are designed for cutting entire groups of bars in commercial lengths.
  • the end position of the scissors 6 after the cut has been made and the corresponding inclined position of the propeller shaft 10 are indicated by dashed lines.
  • the flying shear 6 is followed by an overrun roller table 11, the drive, consisting of the motors 12, of which is set to a higher feed speed than that of the drive roller pair 4 or the straightening machine 5. If, for example, the feed speed of the drive roller pair 4 or the straightening speed 1 m / s, the feed speed of the overrun roller table 11 is 1.5 m / s. In this way, the rod groups divided by the flying scissors 6 into commercial lengths are pulled apart.
  • the overrun roller table 11 is designed as a lifting and braking device 13 in order to brake the partial lengths of rod groups from the roller table and to clear them for the following partial length of rod groups.
  • the lifting and braking device 13 shown in more detail in FIGS. 2 and 3 consists of a rocking grate with lifting plates 14 and 15 extending transversely to the roller table, which can be moved together on a closed elliptical coupling curve 16.
  • the lifting plates 14 are located below the roller table plane of the roller table 11, whereas the lifting plate regions 15 are located below stationary brake plates 17.
  • the brake plates 17 correspond in the area of the roller table 11 between the roller table rollers arranged, fixed and floor plates 18 of the same length (FIG. 3), which have the same length as the movable lifting plates 14, 15 on the one hand and the fixed brake plates 17 on the other.
  • the movable lifting plates 14, 15 pass on their way according to the elliptical coupling curve 16 through the gaps between the fixed base plates of the roller table 11 and the fixed brake plates 17 as receptacles for the rod groups, the rods both on the lifting plates 14 and on the fixed ones Brake plates 17 are able to slip and are braked until they come to rest on the brake plates 17.
  • the designed as lifting and braking device overrun roller table 13 is replicated in this respect a "vibrating trough" according to DE-AS19 00 447 with the difference that the non-slip lifting and braking elements are designed to accommodate groups of bars.
  • a chain transport 19 with subsequent collecting pockets 20 is provided for the transverse movement of the rod groups that have come to rest.
  • the chain conveyor 19 can also be designed as a stacking device for section steel, as several ramp roller tables 11 as well as lifting and braking devices 13 with stacking devices can be arranged one behind the other in the flow direction to match the performance of the rolling mill.
  • the drive for generating the elliptical coupling curve 16 with eccentric discs 21, frame structure 22 with support rollers 23 and a lower, linearly guided guide roller 24 corresponds to the type according to DE-PS17 52 533.
