Definitions

  • the invention relates to a device for guiding blanks emerging from a cross-rolling mill, in particular woodloom, rotating about their longitudinal axis.
  • At least two chains running endlessly in the direction of the runout are arranged evenly distributed on the circumference of the runner, on the chain links of which freely rotatable support rollers are mounted on the lateral surface of the runner in the circumferential direction of the runner.
  • the outlet guide thus consists of two or more, preferably three, chains arranged in the longitudinal axis direction of the roller, which, arranged parallel to the rolling direction, support the outlet movement of the roller and, at the same time, allow the roller to move in rotation. In this way, the torsional moment can be eliminated and, at the same time, it can be ensured that the slug is securely guided and supported in the entire outlet area.
  • a discharge guide designed in this way also enables higher batch speeds without impairing the tolerance and thus the quality of the batch which runs out. Higher carriage speeds enable a good spreading of the system, even if the transport angle determining the feed is smaller due to other system parameters.
  • the support rollers are preferably mounted about axes of rotation running parallel to the direction of rotation of the chains. The superimposed movement of the chain and the rolling movement of the support rollers ensure safe guiding and support of the slug.
  • two chains are provided, on the chain links of which the support rollers are each arranged in pairs with parallel axes lying side by side.
  • two pairs of rollers i.e. four rollers, support the blank at its circumference and thus ensure precise guidance.
  • the support rollers are resiliently supported radially to the slab, so that shocks are mitigated and vibrations are damped.
  • a tensile force can be applied to the slug by increasing the rotational speed of the chains in relation to the sledding speed.
  • the idling movement of the slug is supported in the axial direction by the moving chains, compressions and torsions being prevented by the applied axial pull.
  • the device according to the invention is drawn roughly schematically in FIG. It consists of two endlessly rotating chains 1, 2, which are offset by 180 ° to the slug and are guided around deflection wheels 3 in the longitudinal direction of the slug denoted by 4.
  • a funnel guide 9 is provided between the chains 1, 2 and the rollers (not shown) of the cross-rolling mill, which guides the slug 4 leaving the rolling mill in the direction of arrow 10 between the rollers 7 of the chains 1, 2.
  • FIG 2 a cross section through the chains 1, 2 and the plate 4 is shown. It can be seen that two rollers 7 are arranged on the carrier 6 around axes 11 which are parallel to one another and support the plate 4 on the circumference. The rollers 7 are (not shown) resiliently supported in the carrier 6, the chains 1, 2, as indicated by the arrow 12, are radially adjustable to the plate 4.
  • FIG. 3 shows a cross section through a plate 4 and three chains 1, 2, 2a, each distributed around the circumference by 120 °, the carriers 6 on the chain links 5 each carrying only one support roller 7, which rotates about axes 11 parallel to the longitudinal axis 12 of the plate are freely rotatable.
  • the slug 4 runs out of the rolling mill (not shown), the slug moves in the feed direction 10 and simultaneously rotates in the direction of rotation 13. While the feed direction 10 is caught by the revolving chains 1, 2, 2a in the direction of the arrow 8, the rotation movement 13 by the freely rotatable rollers 7 enables.
  • the slice is through its length in wide ranges Rollers 7 and the chains 1, 2, 2a supported and guided so that even very thin-walled slugs can be transported and supported safely and without problems.
