Definitions

  • the innovation relates to a device for aligning in a cooling bed position on a transport roller table in front of a cross-cut shear in a corresponding number of round rolled rods placed next to one another to the division of the profiled shear knife.
  • Small-caliber and medium-sized bars are usually divided into commercial lengths after leaving the cooling bed on cold shears. It is customary here to feed the shears a large number of roll bars next to one another, which are cut at the same time.
  • scissors knives are used, the cutting of which is adapted to the profile of the rolling stock to be cut. For this purpose, it is necessary to insert the rods into the openings formed by the profile recesses in the knives in order to then start the scissors.
  • the object of the present innovation is to create a device for aligning round rolling stock on the division of the cross-cut shear, with which an automatic threading into the profiled shear blades is possible.
  • the features described in the protection claim are provided which make it possible to automate the process and increase the shear throughput by eliminating the manual insertion of the rolled stock.
  • FIG. 1 denotes 1 of the roller table rollers on which the rolled stock bars indicated at 2 are placed.
  • the profile strip 3 can be seen, which is provided with a multiplicity of recesses 4, the spacing and division of which corresponds to the division of the profiled scissor knife, not shown.
  • the profile bar 3 can be raised and lowered in the direction of the arrow 5. In the direction of the rolling stock there are several at least 2 of these profile strips are arranged at a distance from one another in order to ensure a proper support of the profile bars 2.
  • one of the distribution devices 6 can be seen to the left of it, each of which consists of a first carrier 7 and a second carrier 8. Both carriers are designed to be freely cantilevered in the horizontal direction, the second carrier 8 being able to be raised and lowered in the vertical direction relative to the first carrier 7, as indicated at 9. At the free end of the first carrier 7, a downwardly projecting driver nose 10 is formed, the function of which will be described below.
  • the second carrier 8 is adjustable in the axial direction relative to the first carrier 7.
  • the distribution device is shown retracted into the area of the roller table, the first carrier 7 projecting over the rolling stock bars 2 and the second carrier 8 engaging under the rolling stock bars 2. In this position, the actual distribution function of the new device begins, the operation of which is described below:
  • the rolled stock bars 2 are first pushed close together.
  • the number of rolled bars 2 corresponds to the number of profile recesses in the scissor knife, not shown, and the effective length of the beams 7 and 8 of the distribution device.
  • the second carrier 8 is first raised, whereby the rolling stock 2 is lifted off the roller table 1.
  • the profile bar 3 is also raised ben, in a plane above the roller table 1 but only so far that the receptacles 4 of the profile strip 3 are closed by the second carrier 8 in a lateral overlap, as can be seen in Figures 2 and 3.
  • the distribution cycle begins.
  • both the first and the second carrier 7 and 8 the receptacles 4 in the profile strips are released in succession from the right to the left by the second carrier 8.
  • the second carrier 8 is set relative to the first carrier 7 in the axial direction in such a way that between the driving lug 10 and the end 11 of the second carrier 8 there remains a passage which is open at the bottom and corresponds to the diameter of one of the rolled stock bars 2 to be distributed (FIG. 3a).
  • the rolling stock 2 is placed on the roller table 1 and can be fed to the cold shears in the corresponding division.
  • the device is ready for use again and can start a new working cycle according to FIG. 2 after the divided rolled bars 2 have been separated and removed.
