Definitions

  • the invention relates to a brake trough for rolling rods according to the preamble of the claim.
  • Such a brake trough has become known from US-A-4 054 047, in which the sliding part is fixed and the trough part forming the troughs is designed to be revolver-like and carries out a rotary movement.
  • the rolling rods By rotating the trough part together with the rolling rods located in the troughs, which are guided over the fixed sliding surfaces of the sliding part, the rolling rods are transported to the place where they are ejected.
  • a disadvantage of this construction is that with a fixed slide part and continuously rotating channel part, guide tubes must be provided on the inlet side so that the successive rolling rods to be braked can follow the movements of the channel part. The functional reliability of the brake system is impaired by this disadvantage.
  • Closed troughs of a brake trough for rolled bars have become known from DE-C-465 625.
  • the troughs of this brake trough have continuously open longitudinal slots, which can be closed by reversing movement of the troughs either by means of stationary covers or opened downwards to eject the rolling stock by the tubular troughs being rotatably reversibly controllable about their longitudinal axis, in order to steer one trough by moving the Open 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 can be moved transversely 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 trough part and the sliding part forming the sliding surfaces for ejecting the to rest rolled rods only need a single drive.
  • the troughs of the channel 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, the sliding surface alternately reaches outside due to its defined length during the relative transverse movement between the channel part and sliding part the vertical projection of one of the chambers, the rolling rod located in this chamber can fall down, whereby it expediently gets into a catch of a vibration-appropriate 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 relatively very long brake channel expediently consists of a plurality of channel and slide parts provided with inlet funnels, connected in series in the manner of wire guide tube elements, with a common drive for one of the parts.
  • the embodiment described according to the invention is preferred because the troughs or chambers always lie in the line of alignment of the rolling rods entering the brake trough. As a result, measures can be omitted to guide the rolling rods to be braked in alignment with the respective brake channel.
  • the brake trough As shown in FIG. 1, the brake trough according to a further development of the prior art 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 the computing cooling bed R partially shown in FIG. 2 is arranged.
  • the fixed part of the rake cooling bed R has raised walls W for fastening the brake channel elements.
  • the common drive for all brake channel elements is described. This includes a pivot axis 3 which extends over the entire length of the brake channel and with which at least one drive lever is rotationally connected.
  • the piston rod 5 of a actuating cylinder 6 operated by pressure medium acts on this angle lever 4.
  • the actual brake channel comprises a plurality of pivoted levers 7 which are wedged on the pivot axis 3 and which carry a channel part 8 with two chambers 8a, 8b open at the bottom at the lower end.
  • both chambers 8a, 8b are closed by a uniform, stationary slide part.
  • the sliding surfaces of the sliding part 9 are circular arc shaped according to the circular movement of the channel part 8 is curved, ie 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 8a, 8b and the sliding surface of the sliding part 9.
  • the brake trough shown in Figures 1 and 2 is designed for single-core operation of the upstream rolling mill, i. H. the chambers 8a, 8b of the channel part 8 are alternately fed with the rolling rods 1 and 1a cut by rotating scissors in succession.
  • FIG. 3 shows a preferred exemplary embodiment of the brake trough according to the invention with a sliding part 37 designed as a pendulum body in the central position, which can be periodically pivoted to the right or 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 circularly curved slide 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 part 38.
  • FIG. 3 corresponds in principle to that of the above-described development according to FIGS. 1 and 2, with the difference that it is the sliding part 37 provided with sliding surfaces, the ejector openings 40 of which alternately contain the chambers 38a and 38b for ejecting the ones running therein and for Open the quiet rolled bars.
  • the ejector openings 40 can be arranged so close together that simultaneously running and ejected rods without deflection can occasionally get into the first two catches R1 and R1 of the cooling bed.
