Definitions
- the present invention relates to a method and an apparatus for producing a crimp.
- Crimping is a joining process in which two components are joined together by plastic deformation.
- a crimping that is, a difficult to release mechanical connection between a conductor and a connecting element, such as a plug or a sleeve, can be effected.
- Such crimping may be used as an alternative to conventional bonding techniques, such as brazing or welding, and, when properly fabricated, may provide a reliable electrical and mechanical connection between the two crimped components.
- a gas-tight connection between the two components can be effected, since in the plastic deformation of a crimp blank and, for example, a fine-wire line, a structure can be formed which is largely sealed off against the ingress of oxygen and thus in the interior is protected against corrosion.
- a crimp blank for example in the form of a plastically deformable sleeve element or plug element, is conventionally brought into contact with a second component to be crimped with the crimp blank, for example an end of a cable.
- the crimp blank is formed by pressing with a suitable mold on its side directed towards the crimp blank a suitably shaped crimp forming surface plastically deformed, wherein the second component is generally completely surrounded by the crimp blank and pinched by this.
- Forming tool is this generally displaced by a molding machine by a path in the direction of the crimp blank until the crimp blank with a
- the molding machine can be, for example, a hydraulic, pneumatic or electric press on which the molding tool can be fastened.
- fine-wire lines can be insufficiently permanently compressed. It can therefore come to the individual lines oxygen and increased by oxidation an increased
- Pressing should not be too high or be pressed with a too small mold, as this, for example, in massive and fine-wire lines the
- a quality assurance of a crimp usually conventionally by measuring external dimensions of the crimp, by an optical assessment of the grinding pattern z.
- the aim is to provide a method for producing a high-quality crimp and a device suitable for carrying out the method.
- the internal preload should be greater for stable electrical connections than natural aging relaxation of the materials during the crimping time of use.
- the position of the mold at maximum crimping force can be determined. This is generally directly in the reversal point of a travel of the mold. Furthermore, the position of the
- a force on the return path that is, one of the forming tool, exerted on the crimping blank when crimping from the forming tool onto the crimping blank achieved maximum press force has been reached and the mold is then shifted away from the crimp blank to measure.
- a force on the return path that is, one of the forming tool
- a distance is to be determined between a position in which presses the mold with the highest pressing force on the crimp blank, and a position which reaches the mold during the subsequent displacement away from the crimp blank and at the first time substantially no pressing force is exerted by the mold on the crimp blank more.
- Substantially free of pressing forces can be understood here to mean that, at most, forces are exerted on the crimp blank by the molding tool, which forces can be neglected in comparison with forces which are necessary for the plastic deformation of the crimp blank Essentially press-free "to the effect that a force exerted by the mold on the crimp blank pressing force should be smaller than forces that are experience exerted by the crimp blank by springs during the displacement of the mold on the way back to the mold.
- determining the return path length can be determined how strong the crimp blank after the actual crimping, that is after reaching the
- the return path length to be determined may be determined by measuring a distance between a first reference point, which correlates with the position of the crimp blank, and a second reference point, which correlates with the position of the forming tool.
- the crimp blank can be accommodated in a crimp blank receptacle in which it is held during the crimping process and
- a suitable reference point can be defined on the crimp blank receptacle, which correlates with the position of the crimp blank.
- a reference position may be defined on the mold, preferably in the vicinity of the crimp molding surface. Since the two defined reference points successively move away from one another during the displacement of the mold on the way back of the mold away from the crimp blank, by measuring the distance between the two
- Maximalpresskraft is exerted on the crimp blank, and on the other hand at a time when the mold for the first time no more force on the crimp
- Position measuring device to measure only the position of the mold or a second reference point, which correlates with the position of the mold or its crimp forming surface. It may be advantageous in this case to select the second reference point as close as possible to the crimp forming surface, which plastically deforms the crimp blank during the crimping process. It can thus be ensured that, by measuring the return path length, the resilience path of the deformed crimp blank, which is located between the crimp blank receptacle and the crimp forming surface, is actually determined, and influences, such as, for example, deformation of the mold or of the die Shaping tool moving
- the return path length is measured without contact.
- the distance between the two defined reference points can be measured optically, for example with the aid of a laser distance measuring device.
- a laser distance measuring device can be designed to emit a laser beam from one of the reference points to the other reference point and to re-detect a portion of the laser light reflected there, in order to detect a laser beam
- the non-contact measurement of the return path length can allow a reliable, wear-free determination of the quality of the crimping.
- an optical measurement for example by means of
- Fig. 1 shows an apparatus for performing a crimping method according to an embodiment of the present invention.
- Fig. 2 shows a typical course of pressing forces during a crimping process.
- the figures are only schematic and not to scale.
- a device 1 is shown, with the aid of a crimp blank 3 can be crimped.
- the device 1 has a mold 5 in the form of a punch and a crimp blank receptacle 7 in the form of an anvil.
- the molding tool 5 is fastened to a molding machine 9 which is shown only schematically.
- the molding machine 9 can move the mold 5 in the vertical direction back and forth, as indicated by the arrows 1 1, 13. At its bottom, to the
- Crimp blank receptacle 7 directed side, the mold 5, a crimp forming surface 15 which defines the contour into which the crimp blank is to be plastically deformed during crimping.
- the molding machine 9 is designed by means of a force measuring device 19, the
- Transmitter 17 to transmit.
- a position measuring device 21 is provided for the device 1, by means of which the position of the mold 5 can be measured.
- the position measuring device 21 is realized by means of a laser distance measuring device 23 which is fixedly attached to the crimp blank receptacle 7.
- the laser distance measuring device 23 emits a schematically illustrated time-modulated laser beam 27 in a direction corresponding to the direction of movement 11 1, 13 of the mold 5 during the crimping operation.
- the laser beam 27 is reflected on a reflector 25 attached laterally projecting to a lower end of the mold 5 in the vicinity of the crimp forming surface 15.
- the reflected portion of the laser beam 27 is then detected by a detector of the position measuring device 23. From a phase shift to be measured between the emitted modulated laser light and the detected reflected laser light can be measured over a travel time measurement on the distance x between the
- Laser distance measuring device 23 and the reflector 25 are closed.
- the laser distance measuring device 23 thus allows to determine the position of the crimp forming surface 15 of the mold 5 during the crimping process very accurately.
- a corresponding information is forwarded to the transmitter 17.
- the undeformed crimp blank 3 is first placed on the crimp blank receptacle 7.
- the crimp blank 3 has two tabs 29, 31, which together with a bottom 33 of the crimp blank 3, a space 35 substantially enclose.
- the crimp blank 3 may be one end of a plug or socket to which a cable is to be crimped. In the space 35, the cable or the plurality of exposed strands 37 of the cable is then inserted.
- the forming tool 5 is now successively displaced vertically downward in the direction of the arrow 11 by the forming machine 9.
- the crimp-forming surface 15 comes into contact with the tabs 29, 31 and deforms them during the further descent of the forming tool 5. Deformation takes place largely plastically in this initial stage.
- the material of the tabs 29, 31 partially plastic flows into spaces between the strands 37.
- the deformation of the crimp blank 3 including the strands 37 received therein takes place partially plastically and partially elastically.
- the force F exerted on the crimp blank 3 by the mold 5 is continuously measured.
- the magnitude of the force is not decisive for these measurements, only the points of maximum pressing force and minimum pressing force are to be determined. In order to avoid possible defects due to deformations of the molding machine and / or the molding tool, the measuring device should be close to the crimp blank to be placed.
- the Laserabstandsmessignt 23 may be advantageously mounted close to the support surface of the crimp blank on the crimp blank receptacle 7 and serving as a counterpart reflector 25 may for example be mounted in the vicinity of the Crimpformungs constitutional 15 on the mold 5.
- the mold 5 is displaced vertically downwards until the force measuring device 19 indicates that the force with which the crimping tool 5 presses on the crimp blank 3 corresponds to a maximum pressing force F max . After a defined Zufahrweg the mold moves back up until it leaves the crimp blank.
- a typical curve of the applied pressing force F as a function of the downward displacement x is represented by the curve 39.
- the pressing force F increases slowly during the plastic, elastic deformation of the crimp blank 3. and comes with further relocation in an area in which the press force with the relocation increases more and more. This can be regarded as an indicator that, in addition to the plastic deformation, an increasingly contributing elastic deformation of the crimp blank 3, together with the strands 37 received therein, takes place.
- the maximum pressing force F max is reached, the downward movement of the forming tool 5 is ended.
- the mold 5 is again moved vertically upward, as indicated in Fig. 1 by the arrow 13, to move away on a return path away from the crimp blank 3. Also during this way back is the of the
- Position measuring device 21 continuously the distance x between the
- Laser distance measuring device 23 and the reflector 25 measured.
- the distance x max is measured at the instant in which the maximum pressing force F max is exerted on the crimp blank 3 by the forming tool 5.
- the distance x 0 is measured at which the of the pressing tool 5 during the
- the path difference .DELTA. ⁇ x max - x 0 is an information about the elastic deformation of the crimp blank, that is, about the springing of the crimp blank during the return travel of the mold 5 at.
