Definitions

  • clamps to be used with different sizes of rope must themselves be of different sizes. Thus, it is important that it be possible to tell positively the size of a given clamp, and hence the rope for which it is intended to be used. If the wrong size clamp is used, it is quite possible that the resulting joint will not stand up under the loads and stresses applied to the rope.
  • roll stamps or similar devices may be used to mark the pipes or tubes with a colored marker prior to or during the cutting-off operation of the individual rope clamp,
  • marking punches can be used to emboss characteristic marks upon the finished blanks once they have been cut off.
  • Embossed marks have the great advantage over color marks that they cannot be wiped off or otherwise obliterated at a later date.
  • creation of such embossed marks was complicated and therefore disadvantageous.
  • embossed marks has been solved in accordance with the present invention without the necessity of any special operational steps, i.e. marking occurs at the same time as the tube or pipe is cut off into the individual rope clamp blanks.
  • clamping jaws are used to clamp the pipe during severing of the individual rope clamp blanks therefrom, and at least one of the clamping jaws is provided with means for embossing the identification during the clamping step which is essential in any event.
  • the required permanent marking for rope clamp blanks is obtained without any additional operating step. Because of this, the marking is in the identical position in each instance, the distance between successive marks being identical with the cutoff length of rope clamp blanks, regardless of the size of the rope clamp. Therefore, even if many blanks aae subsequently mixed up together, it is easy to tell with surety what each size is.
  • the embossed marks are provided by raised projections on an insert which is releasably secured in the clamping jaws.
  • opposed inserts can be provided in the opposed clamping jaws, thereby to mark two blanks simultaneously.
  • the insert may be insertable at a right angle to the clamping direction, or may be see.- cured to the clamping jaw by screwing to the clamping jaw, or may be a flat headed screw having raised spots or projections thereon to form the required indicia.
  • each insert may carry several markings of the same type, which therefore become embossed into correspondingly clamped tubes located on top of one another.
  • Large nuubers of pipes or tubes may be clamped simultaneously, particularly with the smaller sizes thereof, and a number of marking dies is provided equal to the number of tubes or pipes clamped, whereby each rope blank clamp is provided with the necessary indicia.
  • FIG. 1 is a plan view of a clamping device with the clamping jaws indicated somewhat schematically. The position being somewhat unrealistic in that one jaw is shown as clamping against a tube or a pipe while the other is retracted;
  • FIG. 2 is a front view taken in the longitudinal direction of the tubes or pipes with the latter shown in crosssection;
  • FIG. 3 is a plan view of the clamping area of one clamping jaw
  • FIG. 4 is a plan view similar to FIG. 3 showing a different embodiment of the invention.
  • FIG. 5 is likewise a plan view corresponding to FIG. 3, showing yet another embodiment.
  • FIG. 6 is a partial section taken along the line VIVI of FIG. 5.
  • FIG. 1 two clamping jaws l and 2 are shown somewhat schematically, being mounted on punch or piston rods 3 for advance and retraction in the direction of the adjacent arrows.
  • the guides for the clamping jaws and the specific driving devices are not shown, but may be conventional.
  • a table 13 (FIG. 2) supports the pipes or tubes which are to be cut, and which are moved in the direction of the arrow 14 in FIG. 1 and thus fed into the clamps 1 and 2 for cutting off by a suitable cutting device such as a saw 15, which is also advanceable and retractable toward and away from the tubes or pipes
  • the left clamping jaw l is shown in clamping position in FIG. 1, but the right clamping jaw is shown in retracted position.
  • the clamping area 4 of the clamping jaw l is shown in FIG. 3.
  • An insert or die 5 is mounted in the clamping area 4, and in the present instance fits in a recess and is held in place by screws 6.
  • the outer surface of the insert 5 is flush with the clamping area 4.
  • Indicia 7 protrude from the surface of the die, and impress into the faces of the pipes or tubes 8 (FIGS. 1 and 2) when the pipes or tubes are clamped between the clamping jaws 1 and 2.
  • four pipes or tubes 8 are clamped at the same time, being in pairs atop one another.
  • the die 5 is engageable with only one pipe or tube, and hence four dies or inserts are provided in accordance, with the setup of FIG. 2.
  • the legend D 20 is impressed into the tube section which ultimately becomes a rope clamp.
  • the insert 9 which slides into place from the side. It comprises a wedge-shaped platelet with dovetail edges, and is inserted in the direction of the arrow 10 into the clamping jaw 2.
  • the outer surface of the insert 9 is flush with the adjacent clamping area 4 of the clamping jaw, with the exception of its protrusions 7 extending therefrom, the protrusions in this instance providing indicia S 6 in the rope clamp blank.
  • the insert may remain in place from being a tight fit, or may be provided with retaining means, as desired.
  • Two groups of protrusions 7 are provided on the single die in FIG. 4, whereby two adjacent tubes or pipes 8 (FIG. 2) may be marked simultaneously by the same die. As will be apparent, the protrusions 7 have the same spacing on centers as the tubes or pipes 8.
  • FIGS. and 6 utilizes a die or insert comprising a screw 11 with a flat head having the protrusions 7 on the outer face or surface thereof, bearing the legend SK 18.
  • Small bores 12 are provided in the outer face of the screw head for engagement by a tool for turning of the screw and hence for replacement thereof.
  • several screws 1 1 may be provided above one another for simultaneous stamping of a like number of tubes or pipes.
  • the inserts 5, 9, and 11 are subject to wear aad tear, and therefore at least in the region of the protrusions 7 are preferably of a wear resistant material such as hardened steel.
  • Apparatus for producing rope pressure clamps and simultaneously providing identifying markings thereon comprising: opposed clamping means for clamping a readily collapsible elongated tube, said clamping means including a clamping surface for applying sufficient holding force without causing collapsing of said elongated tube, severing means positioned adjacent said clamping means for cutting off said tube to form rope clamp blanks, and at least one die removably inserted in said clamping means such that its surface is coplanar with said clamping surface, said die having indicia extending above said co-planar surface for forming permanent marking on the surface of a tube as it is clamped for severing.
  • Apparatus as set forth in claim 3 wherein the die comprises a screw having means on the head for forming the permnnent markings on the surface of a tube as it is clamped for severing.
