Definitions

  • the present invention relates to a clamping device for clamping metal terminals on electric cables and a clamping press including the device.
  • prior devices for clamping metal terminals on electric cables conventionally comprise an assembly of knives or punches pressing the terminal against an anvil, so as to deform or crimp it to lock it both on the insulation and on the metal core of the electric cable.
  • an adjusting head is moreover provided, in turn including two ring-nuts allowing to respectively adjust the position of the knife clamping or crimping the metal portion of the cable and that affecting the insulation portion.
  • the knife positions must be set by the mentioned adjusting head, depending on the load to be applied to the cable portions, thereby providing the desired clamping or crimping.
  • a recovering to starting conditions is at present carried out by operating the adjusting head ring-nuts.
  • the main object of the present invention is to provide a novel clamping or crimping device, which, differently from prior art analogous devices, allows to hold optimum clamping conditions during the overall clamping operation, by quick and simple operating steps not requiring any interruptions of the operating cycle.
  • a further object of the invention is to provide a novel clamping or crimping device allowing to perform in an automatic manner any corrections to the clamping of metal terminals on electric cables, as required because of wear, cable size variations and the like.
  • the clamping or crimping device allows to adjust the load of the knives on the metal terminal and cable, thereby correcting any clamping or crimping defects, quickly and simply, without interrupting the operation.
  • the clamping device comprises control means for controlling the above mentioned correcting operations, which can be performed in a fully automatic manner, i.e. without any manual operations.
  • the reference number 1 shown in Figure 1 indicates the clamping press including, at the bottom thereof, the clamping or crimping device 2 according to the present invention, in turn having an adjustable height bottom or base 3, clearly shown in Figures 3 to 6.
  • Said device in particular, is of a type specifically designed to affix the insulation 14 and metal core 15 of an electric cable 10 to a metal terminal 9 as shown in Figure 10.
  • the device 2 comprises, at the top thereof, an adjusting head 6, including two controlling ring-nuts 12 and 13 for respectively controlling the knives or punches operating on the insulation portion and metal core of the electric cable 16.
  • Figure 2 shows only one of said knives, being herein indicated by the reference 7.
  • the counter-biassing element for counter-biassing the above mentioned knives comprise an anvil 8, thereon the terminal 9 and electric cable 10 are abutted.
  • the anvil 8 is, in turn, supported by the plate 29 of the clamping or crimping device 2.
  • An anchoring plate 4 for anchoring the plate 29 of the device 2 on the adjustable height bottom 3 being moreover provided.
  • the adjustable height bottom or base 3 shown in Figures 3 to 7 comprises a wedge element 11, housed and slidable between a bottom plane or plate 16 and a top plane or plate 17.
  • the sliding of the wedge element 11 can be carried out by a screw 18 provided for adjusting the height of the bottom 3, said screw being threaded inside the wedge element 11 and being adapted to freely turn in a fixed supporting element 19.
  • the rotary drive to the screw 18 is derived from an electric motor 20 ( Figure 5).
  • the bottom plate 16 of the bottom or base 3 of the clamping device 2 comprises a rectilinear wall metal plate, whereas the top plate or plane 17 is provided with an inner slanted wall 22, thereon a corresponding slanted wall 23 of said wedge element 11 slides (Figure 3).
  • Locating means 25, comprising preferably pins, pegs and the like, properly locate and guide on the vertical axis the plates 16 and 17 therebetween the wedge element 11 is slidably housed as controlled by said screw 18.
  • the clamping operation comprises, at the start thereof, an adjusting of the ring-nuts 12 and 13 thereby properly setting the positions of the knives and, accordingly the load provided thereby on the terminal 9 to clamp said terminal 9 to the insulation 14 and metal portion 15 of the electric cable 10.
  • the press 1 is started to operate the device 2 which, by its knives counter-biassed by the mentioned anvil 8 supported by the plate 9, will provide a proper clamping of the terminal 9 to the cable 10.
  • the height of the bottom or base 3 will be proportionately reduced to the amount ⁇ o - ⁇ .
  • the height of the bottom or base 3 will be proportionately increased up to a value ⁇ o + ⁇ .
  • Such a correction performed by also manually operating on the screw 18, can be carried out during the clamping or crimping operation itself, without interrupting it.
  • the clamping or crimping device is provided with means, generally indicated by the reference number 26 in Figure 9, for reading the position of the plate 4, thereby facilitating and making more accurate the correction of the bottom or base 3 height.
  • the above mentioned means can comprise, for example, suitable sensing means.
  • a sensing element adapted to detect or sense the clamping load can be added to the system, at a position suitable for sensing or detecting the clamping or crimping load.
  • such a sensing element could be located, indifferently, either under the plate 29 supporting the clamping device 2 ( Figure 2) or on the knif pushing axis or, simultaneously, in both the mentioned positions (which variations have not been shown).
  • Said sensing or detecting element in turn, would be suitably interfaced with a controlling unit 28 for controlling the height of the bottom or base 3.
  • the control unit 28 would modify in a corresponding manner the height of the base or bottom 3 to recover the starting load value.
