Definitions

  • the invention relates to a crimping machine according to the preamble of claim 1.
  • Such a crimping machine is for example from the patent DE 44 40 835 C1 known to the applicant and is used, for example, to crimp wire end sleeves with a stripped cable end.
  • these wire end sleeves are rolled up as a belt on a drum magazine and conveyed from this via a transport unit to a crimping head.
  • the wire end sleeves or contact elements can also be received individually in a storage unit and then conveyed to the crimping head in a defined position via a suitable feed device.
  • a feed device is for example in the DE 198 31 588 A1 described.
  • the ferrule to be crimped is placed on the stripped cable end by means of a holding unit and then pressed over the crimping head.
  • the cable end can be stripped either externally or using a stripping head integrated in the crimping machine.
  • the crimping machine is used to crimp different cable cross-sections and / or
  • a machine designed as a stripper, crimper
  • a drum magazine and an associated crimping device are provided for each type of ferrule, to which a common drive is assigned, which can optionally be brought into operative engagement with one of the crimping devices.
  • This crimping machine has a storage arrangement with a plurality of drum magazines to which a common transport unit and a common crimping head are assigned, so that the outlay in terms of device technology is significantly reduced compared to the solution described above.
  • This crimping machine is characterized by high productivity.
  • a certain disadvantage is seen, however, in the fact that the required shuttle has a comparatively complex structure and accordingly takes up space and it is not possible to strip the insulation.
  • the invention is based on the object of creating a machine suitable for stripping (stripping) and crimping, by means of which a flexible production is made possible with a comparatively simple structure.
  • the crimping machine is used to press contact elements with an end section of a conductor, for example a cable end.
  • the crimping machine has a storage arrangement comprising a plurality of magazines, each magazine being assigned a transport unit for transporting the contact element, for example a wire end sleeve, to a cutting device.
  • the crimping machine also has a centering device for positioning the conductor end section with reference to a crimping head, via which the contact element is crimped to the end section of the conductor (cable end).
  • a guide device is arranged between the crimping head and the cutting device, via which the separated contact element is guided towards the crimping head.
  • This guide device has a large number of entrances, each of which is assigned to a transport unit or a contact element cross-section. These inputs open into an output on the crimping head via channels along which the contact element to be crimped is guided. There the contact element is taken over and inserted into the crimping head.
  • the contact element to be crimped is thus made without the interposition of a complex shuttle or the like led directly into the effective area of the crimping head.
  • This guidance is implemented with a minimum of outlay in terms of device technology by the described guidance device, which essentially manages without moving components and conveys the contact element by the action of gravity, possibly supported by the application of compressed air or the like.
  • the guide device is designed like a funnel, the entrances being designed on the one hand to lie next to one another. From these, the channels then extend in a converging manner to the opposite common outlet.
  • these channels in the crimping machine are preferably oriented in the direction of gravity, i.e. in the vertical, so that the transport of the contact elements within the guide device is at least supported by gravity.
  • the transport can be accelerated if a suitable acceleration device is provided, via which the movement of the contact element in the guide device is supported.
  • a suitable acceleration device can, for example, have a compressed air channel via which a compressed air jet is directed onto the contact element. Accordingly, each channel can then be assigned a compressed air channel or all channels can be assigned a common compressed air channel.
  • the operational safety can be further improved if a sensor is arranged in the area of the exit of the guide device, which sensor detects the approach of a contact element.
  • the crimping head and the associated functional elements are then controlled by means of a control unit via the sensor signal that is then generated.
  • a stripper is also integrated into the crimping machine.
  • the crimping machine can be provided with a control panel / display via which the cable cross-section / contact element type can be selected. Depending on this input, the transport unit and the cutting device, the stripping unit and the crimping head and other functional elements are then controlled via the aforementioned control unit.
  • the crimping machine is preferably operated pneumatically. In principle, however, an electric motor actuation can also be implemented.
  • Figure 1 shows a three-dimensional representation of a crimping machine 1, with which five different wire end sleeves or other contact elements and corresponding cable cross-sections can be processed.
  • the wire end sleeves 2 are each provided as a strap.
  • these belts are wound onto five drum magazines 4a, 4b, 4c, 4d and 4e, which are rotatably mounted on a housing 8 of the crimping machine 1 via a magazine holder 6.
  • the belt straps with the wire end sleeves 2 are then each unwound from the drum magazine 4 via a transport unit, these transport units being combined to form a transport module 10 which is placed on the housing 8.
  • a display 12 is arranged on the visible housing front, which is designed, for example, as a touch display in order to be able to make appropriate inputs for selecting the cable cross-section or the like.
  • a centering and guiding device 14 is provided approximately in the middle of the illustrated front side, which bulges inwardly in an approximately funnel-shaped manner and via which the cable ends 16 to be processed can be fed.
  • five different cable cross-sections can be processed with the illustrated crimping machine 1.
  • the crimping machine 1 can also be designed for processing more or fewer cable cross-sections and a corresponding number of ferrules.
  • FIG 2 shows a rear view of the crimping machine 1 according to Figure 1 .
  • the five drum magazines 4a, 4b, 4c, 4d, 4e can be seen in this illustration, the belt straps not being shown. These then run from the aforementioned drum magazines 4a, 4b, 4c, 4d and 4e into the transport module 10, which is placed on the housing 8.
  • the crimping machine 1 described is operated by compressed air.
  • a corresponding compressed air supply 18 is at the in Figure 2 arranged rear side shown.
  • a power connection 20 with an on / off switch and further sockets / connections for signal transmission or power supply are then provided.
