Definitions

  • the invention relates to pressing pliers, in particular for pressing cable lugs or the like onto electrical conductors, with two pressing jaws that can be pivoted relative to one another, with a pressing die that is designed with a plurality of different pressing depressions over a circumference relative to an axis of rotation being rotatably mounted in each pressing jaw, and one pressing die related to the Axis of rotation between two back plates is added.
  • Crimping pliers of the type in question are known, both as hand-operated and as motor-driven tools. These are used, for example, to attach cable lugs to electrical conductors.
  • an in particular tubular workpiece is pressed together between the two press jaws with, for example, hexagonal press depressions of the press dies.
  • a different pressing profile i.e. a different opening cross-section of the pressing troughs of both pressing dies, is usually required for each cable cross-section.
  • a corresponding adjustment of the press dies is carried out in known tongs by rotary displacement of the press dies about their axes of rotation, with the press troughs of both press dies having to be matched to one another for proper pressing of the workpiece.
  • Such a crimping pliers is, for example, from DE 196 28 752 A1 ( US 5,802,908 A1 ) known, also from the WO 2016/096732 A2 .
  • a pressing tongs is known, in which the pressing dies are acted on by means of a leaf spring transversely to an axis of rotation of the pressing dies, the pressing dies also being adjustable under the action of the leaf spring.
  • the invention is concerned with the task of further improving a pressing tongs of the type in question, in particular with regard to the pressing result on the workpiece.
  • Free rotational mobility is necessary to enable the press dies to be able to rotate relative to the jaw plates flanking them. This is the case with the known press jaw solutions due to a left axial play of the press die between the jaw plates.
  • the press die is accordingly arranged between the jaw plates so that it can be moved in the direction of its axis of rotation by a dimension of preferably a few tenths of a millimeter.
  • the press dies can be set according to the bracing. This definition takes place at least in the pressing position of the pressing tongs, more preferably over a large pivoting angle of the pressing jaws up to almost every pivoting position of the pressing jaws outside of an open position of the pressing jaws. The axial play that occurs when the press jaws are in the open position is eliminated.
  • the pressing results in a bracing position of the press dies between the jaw plates, between which the (respective) press die is accommodated. In any case the open position of the pressing jaws, the pressing tongs open position, the pressing dies are in the release position enabling an adjustment.
  • the bracing can be released and the release position with respect to the pressing die can be given accordingly. In this release position, the axial play necessary for the rotary displacement of the press die can be present.
  • the press dies can thus be fixed in a strictly opposite orientation in the course of the pivoting of the press jaws in the direction of the pressing position, although these press dies can nonetheless be freely rotated when the press jaws are open.
  • the press die In the bracing position, the press die is fixed in the direction of the axis of rotation by bracing the jaw plates.
  • the jaw plates of the opposing pressing jaws work together with a common connecting link.
  • the connecting strap can offer the axis of rotation for the press jaw or the pair of jaw plates to form a press jaw.
  • the jaw plates of both press jaws which are assigned to a connecting strap, are each articulated on the common connecting strap such that they can be pivoted about an axis of rotation. This results in a relative movement between the jaw plates and the connecting link.
  • This relative movement is used according to the invention to generate the tension.
  • one of the parts, the connecting strap or the jaw plate can have an elevation in the direction of the axis of rotation and the other part can have a recess adapted to the elevation.
  • a surface can be formed on the relevant part. At the same time, this surface can form a parting plane directed transversely to the axis of rotation between the connecting strap and the facing cheek plate.
  • An imaginary extended extension of the surface up to the area of the recess, corresponding to an imaginary surface extension spanning or penetrating the recess, can be penetrated by the elevation in the non-tensioned state (release position) of the jaw plates.
  • the elevation can accordingly lie in the recess or engage in it.
  • both parts namely preferably the connecting strap and the facing jaw plates, can also have an elevation projecting beyond the surface facing the respective opposite part in the axial direction.
  • the two elevations of both parts can work together to achieve the braced position.
  • a surface touching a first elevation and parallel to a pivoting plane of the parts for example a free contact surface of the elevation pointing in the direction of the other part, can in the release position in an imaginary extension of this (contact) surface in the pivoting direction of the parts increase the elevation of the other part prevail.
  • the two elevations viewed in the pivoting direction can at least partially overlap.
  • This overlap can be completely eliminated in the bracing position.
  • a partial overlapping in the pivoting direction can also be provided in this bracing position, but with an overlapping dimension viewed perpendicularly to the geometric axis of rotation, which is smaller than the overlapping dimension in the release position.
  • the elevation In the clamped state or in the clamped position, the elevation can have completed a relative movement in the direction of the imaginary extended extension of the surface in the area of the recess or beyond. According to a preferred embodiment, the elevation can completely leave the area of the recess during the pivoting displacement of the pressing jaw from the open position in the direction of the pressing position, after which the elevation is supported on the surface of the part surrounding the recess.
  • This can, as is also preferred, lead to compressive stress on the jaw plate having the recess or the elevation lead, which compressive stress acts essentially in the direction of the orientation of the axis of rotation.
  • the compressively stressed jaw plate acts in the axial direction directly on the press die or, for example, on a hub or the like carrying the press die, for the corresponding bracing of the press die between the two jaw plates.
  • the elevation can be spherical in a cross section in which the axis of rotation is represented as a line.
  • a contour of the elevation resulting in this cross section and pointing in the direction of the other part can also be depicted in the form of a segment of a circle, for example in the shape of a semicircle.
  • the elevation can be formed by a ball caught on the relevant part. If necessary, the ball can be freely rotatably supported in the relevant part, for example by being received in a correspondingly shaped socket-like recess.
  • the elevation can also be wedge-shaped in a cross-section, correspondingly having a run-on slope for interaction with a portion of the recess provided in the other part or a counter wedge formed on the other part.
  • a manually operated pressing tongs 1 in a working position, ie a pressing position showing top view.
  • the pressing tongs 1 are constructed essentially symmetrically to an axis xx and have two pressing jaws 2, 3 and two handles 4, 5 designed as angle levers. The latter are connected to one another at their angled ends by a pivot pin 6 arranged on the axis of symmetry xx.
  • the pressing jaws 2, 3 are articulated with their free end regions on the handles 4, 5, with the pressing jaws 2, 3 and the handles 4, 5 passing through bolts 7, 8 being provided, which are secured with spring washers 9, 10 .
  • the pressing jaws 2, 3 are preferably connected both on the top and on the underside, corresponding to the outwardly facing flat side of the jaw plates, by connecting straps 15, 16, which in turn are connected to one another by axle bolts 17, 18 passing through the pressing jaws 2, 3 are connected.
  • a connecting strap can also be provided only on one side and opposite, for example, a rivet head formed on an axle bolt.
  • the geometric axes of the bolts 7, 8, the pivot pin 6 and the axle bolts 17, 18 are aligned transversely to the axis x-x and perpendicular to a plane extension of the pressing jaws 2, 3 with respect to their broad sides.
  • the axes of rotation of the pressing jaws 2, 3 are formed by the axle bolts 17, 18, as a result of which the pressing jaws 2, 3 are divided into short front lever arms 19, 20 and longer rear lever arms 21, 22 facing the hinge bolts 7, 8.
  • a respective press die 23, 24 is rotatably mounted on an axis 25, 26.
  • the axes 25, 26 each pass through both jaw plates of the pressing jaws 2, 3 and are secured on both sides, for example by means of a screw connection.
  • the geometric axis of rotation of the press dies is denoted by y.
  • the press dies 23, 24 have the outline shape of an even polygon. In the exemplary embodiment shown, the press dies 23, 24 are designed as regular hexagons in plan.
  • FIG. 1 In a top view, for example according to FIG figure 2 show the press troughs 27, 28 the shape of half an equilateral hexagon.
  • the working position ie in the pressing position according to the figures 1 , 2 and 9 to 12 two press depressions 27, 28 with the same opening cross-section together form a regular hexagon for pressing cable lugs, connectors or the like onto electrical conductors, etc.
  • pressing depressions 27, 28 of the same size and adapted to the pressing are to be brought into the working position. This is done by rotating the press dies 23, 24 about the axes 25, 26.
  • a press die 23, 24 is provided with an associated driven wheel 31, 32, which is connected to it in a rotationally fixed manner, in the direction of the axis of rotation y, in each case in a side-by-side arrangement.
  • Output gear 31, 32 and press die 23, 24 extend essentially in the space delimited by the jaw plates 11 and 12 and 13 and 14, respectively.
  • a distance a remains, particularly in the open position of the pressing tongs, which results from the fact that the clear distance between the inner surfaces facing one another of two jaw plates 11 and 12 or 13 and 14 forming a pressing jaw 2 or 3, viewed in the direction of extension of the axis of rotation y, is greater than the sum of the thicknesses of output wheel 31, 32 and press die 23, 24, also viewed in the direction of the axis of rotation y.
  • a position in which the said distance is given is referred to as the release position.
  • the distance a is a few tenths of a millimeter, for example up to 3 tenths of a millimeter or just up to 2 tenths of a millimeter.
  • this axial play is practically no longer present in order to prevent the pressing dies 23 and 24 from not being exactly aligned with one another when viewed transversely to the direction of the axis of rotation y, namely possibly having an offset in the magnitude of the distance a.
  • the pressing dies 23 and 24 are fixed in the pressing tongs pressing position. This fixing takes place as a result of a tensioning of the jaw plates 11, 12 or 13, 14 flanking the press die 23 or 24 in the direction of the axis of rotation y.
  • the press jaws are thus in any case in the pressing tongs pressing position in the bracing position.
  • This bracing is achieved by a relative movement between one of the connecting lugs 15, 16, in the illustrated embodiment the connecting lug 16, and the cheek plate 12 or 14 immediately following in the direction of the axis of rotation y.
  • a change between the release position and the bracing position takes place in the case of a ready-to-use mounted pressing tongs, as is considered throughout here, preferably with each change between the pressing tongs pressing position (compare, for example, figure 2 ) and the pressing tongs open position (compare e.g figure 3 ).
  • one of the parts that interact in this respect namely the jaw plate 12 or 14 or the connecting strap 16, has an elevation 47 pointing in the direction of the other part.
  • the elevation 47 is formed on the connecting strap 16, with the elevation 47 protruding over the surface 48 of the connecting strap 16 facing the jaw plate 12 or 14 in the direction of the axis of rotation y, as shown in FIG figure 11 shown with a dimension which corresponds to the distance dimension a for the axial play.
  • the elevation 47 protruding over the surface 48 of the connecting strap 16 plunges into an associated and adapted recess 49 of the other part, here the jaw plate 12 or 14 .
  • the recess 49 is to that of the connecting strap 16
  • Pointing surface 50 of the jaw plate 12 or 14 is open and has a depth viewed in the direction of the axis of rotation y, which allows the elevation 47 to be completely accommodated.
  • the elevation 47 passes through an imaginary extended extension e of the surface 50 surrounding the recess 49 within the recess 49.
  • the axial gap dimension (distance a) results in the area between the facing inner surfaces of the associated jaw plates of a press jaw 2, 3.
  • the press die 23 or 24 can be rotated to set a correct press trough 27, 28.
  • the pressing jaws 2 and 3 are moved from the open position of the pressing tongs into a pressing tongs pressing position as shown in FIG figure 9 pivoted. At the same time, this causes a pivoting displacement of the recesses 49 on the jaw plate, which causes the elevations 47 on the connecting lug side to emerge. Along with this, with the elevations 47 being supported on the facing surface 50 of the jaw plate 12 or 14, there is an elastic deformation of the jaw plate in the direction of the opposite jaw plate of the same press jaw 2 , 3.
  • the relevant jaw plate 12 or 14 is deformed in the direction of the axis of rotation y by the extent of the increase, corresponding at least approximately to the extent of the distance a, in such a way that with appropriate tensioning of the press die and the associated output wheel between the jaw plates of a press jaw 2 , 3 the axial play of the press die is eliminated.
  • the pressing dies 23 and 24 are aligned with one another in the pressing tongs pressing position due to the elimination of the axial play given in the open position.
  • each jaw plate 12 and 14 Associated with each jaw plate 12 and 14, at least one elevation 47 and one recess 49 can be provided. In addition, a plurality of elevations and recesses can bring about the desired bracing.
  • two elevations 47 arranged diametrically opposite one another with respect to the axis of rotation y are formed on the connecting plate 16 for each jaw plate 12 or 14, to which correspondingly positioned recesses 49 in the jaw plates 12 or 14 are assigned.
  • a total of four such elevations 47 can be provided on the inside, i.e. assigned to the surface 48 of the connecting strap 16, which are arranged along a geometric line that runs in the longitudinal extension of the connecting strap 16 and transversely to the axis of rotation y, which geometric line more preferably the geometric axis of rotation y of both axes 25, 26 intersects.
  • the elevation 47 can be formed by a ball 51 caught in the connecting bracket 16 .
  • This can lie in a corresponding socket-like receptacle 52 of the connecting strap 16 (cf figure 14 ), wherein the depth of this receptacle 52 viewed perpendicularly to the plane of the surface 48 is selected such that the ball 51 protrudes beyond the surface 48 by a dimension viewed perpendicularly to the surface 48, which projection dimension essentially corresponds to the axial play dimension (distance dimension a ) corresponds to the press die.
  • the elevation 47 can also be an integral component, for example, of the connecting strap 16, further, for example, as a result of an elevation formed from the same material and protruding over the surface 48.
  • This can be further illustrated in a cross-section in which the axis of rotation y is represented as a line (cf figure 16 ), be designed in the shape of a circular disk.
  • the increase 47 according to the sectional views in the Figures 19 and 20 be formed by a wedge formation 53 projecting beyond the surface 48, having a ramp 54 which, starting from the surface 48, merges into a bearing surface 55 which runs parallel to the surface 48 and is spaced perpendicularly to the surface 48.
  • the wedge formation 53 can dip into a correspondingly adapted recess 49, for example in the back plate 12 or 14 (cf figure 20 ).
  • the mode of operation corresponds to the mode of operation described above with regard to a spherical elevation 47.
  • an elevation 58 protruding over the relevant surface 50 for example in the form of a counter-wedge formation 56, can be provided, which in the pressing tongs open position or release position can rest with a ramp 57 against the ramp 54 of the wedge formation 53.
  • the contact surface 55 of the elevation 47 or the contact surface 59 of the elevation 58 viewed in the direction of rotation of the pressing jaw, penetrates the elevation of the other part.
  • the respective increase is increased Education compared to the associated surface 48 or 50, which essentially corresponds to about half the axial play, ie about half the distance a.
  • the contact surface 55 also acts on the jaw plate 12 or 14 for elastic deformation in the pressing tongs pressing position (bracing position), either directly over its surface 50 in a configuration according to FIG figure 20 or on the facing contact surface of the counter-wedge formation 56 in an embodiment according to Figures 17 to 19 .
  • the rotary displacement of the press dies 23, 24 is synchronized. This is achieved by a constant geared coupling of the pressing dies 23, 24, which coupling is independent of the pivoting position of the pressing jaws 2, 3.
