Definitions

  • the invention relates to a brake trough for rolled bars, in particular round material, which run out of a rolling mill at high speed, consisting of a trough part which forms at least two adjacent troughs for lateral guidance of the rolling stock, and a sliding part which forms sliding surfaces for the rolling stock, whereby the channel part or the sliding part relative to the other, fixed part is adjustable transversely to the rolling stock in such a way that the tread bars located in the troughs are released by the transverse movement alternately to free fall from the troughs.
  • Such a brake trough has become known from DE-A1-20 08 250, in which the trough part forming the troughs is fixed and the sliding part is designed as a pendulum body which is driven so as to be reversibly pivotable about an upper longitudinal shaft extending in the running direction of the roller bars. Due to the alternating pivoting away of the sliding surfaces of the pendulum body carrying the two rolling rods, the rolling rods are ejected alternately, whereby according to the prior art a gradual braking of the rolling rods is provided in multiple channels.
  • a disadvantage of this construction of a brake trough is that the troughs are open at the top, so that in particular thin round material can easily be made can escape the channels. This affects the functional safety of the brake system.
  • Closed troughs of a brake trough for rolled bars have become known from DE-A-465 625.
  • the troughs of this brake trough have continuously open longitudinal slots, which can be closed by reversing movements of the troughs either by means of stationary coverings or opened downwards to eject the rolling stock, in that the tubular troughs can be rotatably reversed about their longitudinal axes, in order to steer one trough each open the longitudinal slot from the area of an overlap so that the rolled rod that has come to rest in the trough is ejected by free fall.
  • This known brake channel 'requires a controllable rotary drive for each channel, in contrast to the solution according to DE-A1-20 08 250, in which the sliding part designed as a pendulum body is transversely movable by a single drive.
  • the invention has for its object to brake the rolling stock in closed troughs while maintaining the advantage for the relative movement between the trough part forming the troughs and the sliding part forming the sliding surfaces for ejecting the Rolling bars that have come to rest only require a single drive.
  • the troughs of the trough part are formed by two downwardly open chambers which are closed by the sliding surface of the sliding part in the middle position of both parts which are movable relative to one another. If, due to its defined length, the sliding surface in the case of the relative transverse movement between the channel part and the sliding part alternately reaches outside the vertical projection of one of the chambers, the rolling rod located in this chamber can fall downwards, where it is used moderate in a rest of a swing rake cooling bed. It is not possible for the rolling rods to break out during the braking process, since the central positions of the two parts which are movable relative to one another are in the chambers which are closed on all sides.
  • the brake trough according to the invention since the brake trough according to the invention must have a relatively large length, it expediently consists of a plurality of trough and slide parts, provided with inlet funnels and connected in the manner of wire guide tube elements, with a common drive for one of the parts.
  • the invention is independent of whether the channel part forming the channels or troughs is stationary and the slide part is movable transversely, or vice versa.
  • the embodiment is preferred in which the channel part forming the channels is stationary and the slide part is movable transversely, the chambers of the channel part being separated from one another by a web which, in the central position of the slide part, closes an ejector opening assigned to both chambers within the slide surface of the slide part, wherein the ejector opening can be controlled alternately under one or the other chamber by the transverse movement of the sliding part.
  • This embodiment is advantageous because the troughs or chambers are always in the line of alignment of the rolling rods entering the brake trough.
  • the inlet side of the brake channel must be extended by stationary guide tubes for the successive, braked rolling rods for each chamber swivel tubes are provided, which inevitably follow the movements of the channel part or the chambers.
  • the brake trough according to the invention consists of a plurality of individual elements A, B, C, etc. in close succession, the first brake trough element A, which, like element C, is only partially shown, at the beginning of FIG 2, partially shown cooling bed R is arranged.
  • the stationary part of the cooling bed R has raised walls W for fastening the brake channel elements.
  • the actual brake channel comprises a plurality of pivoted levers 7, which are wedged onto the pivot axis 3 and which carry a channel part 8 with two downwardly open chambers 8 a 8 b at the lower end.
  • both chambers 8 a, 8 b are closed by a uniform, stationary slide part 9.
  • the sliding surface of the sliding part 9 is curved in a circular arc in accordance with the circular movement of the channel part 8, i. H. the center of curvature of the sliding surface is the center line of the pivot axis 3.
  • a slight play is set between the webs of the channel part 8 comprising the two chambers 8 a, 8 b and the sliding surface of the sliding part 9.
  • transverse slots S F ig. 3
  • the channel part 8 is designed for single-core operation of the upstream rolling mill, that is, the chambers 8 a and 8 b of the channel part 8 are alternately fed the rolling rods 1 and 1 a cut by rotating scissors in succession.
  • the feed pipes for the rolling rods 1 and 1 a in front of the first channel element A and their special features will be explained later in connection with FIG. 6. It is assumed that the rod 1 a comes to rest due to the braking effect of the sliding part 9 and a web part of the channel part 8, the subsequent rod 1 a entering the chamber 8 b. To the end throw the rod 1, the channel part 8 is now cross-controlled by a pivoting movement of the pivot lever 7 clockwise as far as Fig. 3 shows.
  • the chamber 8a leaves the cover area of the sliding part 9, so that the roller rod 1 can freely exit downwards and is fed via the inclined cooling bed walls W to the first catch of the cooling bed R.
  • the rod 1a in the chamber 8b follows this transverse displacement of the channel part 8 to the left. If the pivot lever 7 or the channel part 8 returns to the central position according to FIG. 1, a next roller rod can enter the chamber 8 a, which is now closed again.
  • the ejection position of the channel part 8 for the rod 1 a is indicated by dash-dotted lines in FIG. 3. In both ejector positions, the transverse slots S are - as can be seen in FIG.
  • the minimum length of the transverse slots S thus corresponds at least to the entire transverse displacement path of the channel part 8.
  • FIG. 4 to 6 corresponds in its design to the SLIT method used in the rolling mill, i. H. Rolling rods 1 with 1 a and 2 with 2 a are rolled together and separated by longitudinal slits.
  • the embodiment according to FIG. 4 differs from that according to FIG. 2 in that the channel part 18 has four downwardly open chambers and two fixed slide parts 19 separated from one another by a free ejector space in a mirror-image arrangement, each in the center position of the channel part 18 shown seal an adjacent pair of chambers.
  • each slider 19 is of course assigned its own hanging bolts 10.
  • the pivot lever 17 is widened in accordance with the channel part 18.
  • the ejector chamber located between the slide parts 19 is divided into two halves by vertical, stationary separating bars 20 if the rolling rods released into this ejector chamber are to be fed to adjacent catches of the computing cooling bed R.
  • FIGS. 5 a to 5 c show the central position of the channel part 18 relative to the two slide parts 19, which form the common ejector space 21 between them.
  • the individual rods 1 and 1 a are fed to those chambers of the channel part 18 which are simultaneously opened when the channel part 18 is pivoted, as shown in FIG. 5 b.
  • the rods 1 and 1 a which have come to rest at the same time because of their simultaneous infeed, also emerge downwards in free fall. 5 b or in the middle position according to FIG.
  • FIG. 6 shows the situation in front of a brake trough according to FIG. 4.
  • M recognizes treads or chambers 18a to 18d of the trough part 18 of a first brake trough element A shown schematically in FIG. 6 on the right (FIG. 1).
  • the funnel-shaped design of the chambers can be seen on the inlet side.
  • Upstream pivot tubes 23, 24, 25, 26 are provided for each chamber, which are mounted on the inlet side pivotally and are so connected to the outlet side of hinge bolt 28 on the trench portion 18, that each pivot tube follows the movement of the groove portion in the sense that the S chwenkrohre constantly the chambers 18 a to 18 d assigned to them.
  • FIG. 7 shows the exemplary embodiment of the preferred solution with a sliding part 37 designed as a pendulum body in the central position, which can be periodically pivoted to the right and left about a pivot axis 33.
  • This embodiment is also designed for two-wire operation and therefore has two trough parts 38, each with two downwardly open chambers 38a and 38b, which are attached to fixed arms 39 along their length. In the illustrated central position of the slide part 37, these chambers are closed by the circular sliding surface 37a of the slide part 37.
  • the two ejector openings 40 of the sliding part are closed by the webs 38c of the channel parts 38.
  • the slide part 37 provided with sliding surfaces, the ejector openings 40 of which alternately open the chambers 38a and 38b for ejecting the rolling rods that are running and come to rest.
  • the ejector openings 40 can be arranged so close together that simultaneously running and ejected rods can occasionally get into the first two notches R1 and R2 of the cooling bed without deflection.
