Definitions

  • the invention relates to a device for bare grinding of scaled Hot strip or its free ends in a belt system especially in preparation a connection by welding, wherein the grinding device with two parallel guided endless sanding belts and equipped with support rollers is, of which the one endless sanding belt with the tape top, and at the same time the other endless sanding belt with the belt underside for grinding in working contact can be brought.
  • the upper endless sanding belt is at the top of the rolled strip and the lower rolled strip is in working contact with the underside of the rolled strip brought.
  • the invention is based on the object, a device for finish grinding specify of scaled hot strip, which the grinding process of the scaled Bandes in as short a time as possible to reduce downtime the band in the inlet part of a continuously operating conveyor system as possible largely to cut.
  • both endless abrasive belts are aligned transversely to the direction of the hot strip and that the Grinding device transverse to the direction of the hot strip by a distance accordingly at least the distance between two adjacent support rollers is formed movable back and forth
  • An embodiment of the grinding device provides that each abrasive belt over a this driven roller bench is stretched.
  • the grinding device is designed such that each roller bank for Belt grinding on an area of the upper side of the belt or the lower side of the belt Hot strip at its standstill with grinding force can be applied.
  • a further embodiment of the grinding device provides that the roller banks are mutually connected by guides with a variable spacing such that their supporting roles face each other.
  • the grinding device is aligned transversely to the direction of tape travel.
  • the roll banks are connected by guides, so that the support rollers exactly opposite each other.
  • An embodiment of the grinding device provides that the ends of the roller banks are connected to one another in a variable-spacing manner via guides, so that between the role banks an oblong-rectangular grinding space results, what causes the belt to be ground through this closed grinding space must be led in and out. If this is for technical reasons is considered disadvantageous, the invention provides in a further embodiment the grinder ago that they in shape at the front open fork with two spaced apart parallel distance tines is formed by which each with a continuous sanding belt having a roller bank and preferably with a belt clamping device and with means for mutual Distance adjustment is equipped.
  • the grinding device according to the invention shown in Figures 1 and 2 is once in the passage position (Figure 1) and in the working position ( Figure 2).
  • the grinding device is with two parallel Endlosschleifbändem 4 or 5 equipped, of which the one endless sanding belt 4 with the tape top 6, and at the same time the other endless sanding belt 5 with the band lower side 7 to Loops can be brought into working contact.
  • Each abrasive belt 4, 5 is about this one drivable roller bank 8, 9 stretched.
  • each roller bank 8, 9 for belt grinding to a surface of the tape top 6 and the band underside 7 of the Hot strip 1 at its standstill with grinding force can be applied.
  • the endless sanding belt is stretched over in each case a roller bank 8, 9, in which at least one Roller 12 or 13, preferably the first or last role, is driven.
  • the support rollers 12, 13 of two roller banks 8, 9 are mounted in frame 32 and are used for grinding as shown in Figure 2 against the stopped Band created.
  • the grinding device is transverse to the direction of strip 14th aligned.
  • roller banks 8, 9 are connected to one another via guides 10, 11 in such a way that that they face each other.
  • the aforementioned Arrangement of the grinding device slightly more than the distance of the Support rollers, that is to say around the area 15 back and forth.
  • the grinding device by a respective belt clamping device 19 and 20 supplements, as shown in Figures 3 and 4.
  • the band clamps 19, 20 hold the band 1 in the grinding device in a stable position.
  • the grinding device in a preferred embodiment in the form of a fork 16 open at the front two spaced apart parallel distance tines 17, 18 is formed be, each of which with a an endless belt 4, 5 having roller bank 8, 9, and preferably with a belt clamp 19, 20 and with Means 21, 22 is equipped for mutual distance adjustment.
  • FIG 7 is a kind of family tree a belt system 24 with two of Abrollhaspeln 30, 31 unrollable hot bands 1, 1 'shown, the pulleys over be merged at a point 25.
  • the first grinding station 29 Since the first grinding station 29 is arranged directly behind the dividing shear 23, can the cleaned after the grinding process point directly back into the scissors become. Thereafter, the partial section is done. This has the advantage that the tape in undivided Condition is ground and therefore when grinding an extraordinary has good stability.
  • the other positioning possibility is that a grinding device 28 arranged directly after the merger of the two inlet belt levels 25 can be.
  • the end of the tape 2 and the new beginning 3 in the band Grinding device can be positioned and ground simultaneously, as can be seen from the Figure 8 shows.
  • the general advantage of the invention with the aforementioned positioning options results from the fact that instead of a laser welding machine for welding of band ends 2, 3 a conventional roll seam welding machine can be used to hot strips 1 and their free ends 2, 3 with each other to weld. Roller seam welding machines are according to experience at least a factor of two cheaper. The advantage of this welding device is also that they in the conversion of an existing band line for the use of hot strip, the investment of a laser welding machine unnecessary power.
  • the invention increases the cost-effectiveness of welding two strips or tape ends and is also suitable for retrofitting to existing conveyor systems.
