  • harnesses in motor vehicles consist of a variety of different electrical lines that must be provided by crimping with plugs or Crimpanschlußbau former.
  • the quality assurance of the crimping processes takes place, for example, in that during the crimping the force-displacement characteristic curve of the tool parts is picked up and compared directly with a desired force-displacement characteristic stored in the crimping device or that from the measured force Path characteristic measured data to be compared with the stored target data.
  • the setpoint data or the setpoint force-displacement characteristic are determined during commissioning of the tool.
  • the invention has the object of developing a generic method to the effect that during operation of the crimping device with different tools despite short tool change times a perfect quality of the crimped connections is achieved.
  • the invention is further based on the object to provide a generic crimping tool for performing the aforementioned method. It is a further object of the present invention to provide a crimping apparatus for using such a tool.
  • the inventive method is further formed with the features of claim 2 in an advantageous manner.
  • the claim 3 is directed to the crimping tool, with which the corresponding part of the invention task is solved.

  • the crimping device according to claim 6 is further formed with the features of claims 7 and 8 in an advantageous manner.
  • Figures 1 and 2 are largely taken from the aforementioned DE 4 038 658 A1, the content of which is made as an example of a crimping apparatus and a crimping method to the content of the following application.
  • the generally designated 2 crimping device is formed by a crimping press, in which a means of a drive not shown in detail upwardly and downwardly movable punch in an adapter 4 ends.
  • the adapter 4 protrudes into a tool receiving space 6, which has a plate 8 below, which is supported on a foot 12 of the crimping device 2 via a load cell (only the line 10 leading to the load cell is shown).
  • a control panel 14 is provided which forms an interface to a data processing device 15 with microprocessor, data memory, program memory, etc. contained in the crimping device.
  • a total of 14 designated in Figure 2 tool can be used.
  • This tool includes a connectable to the adapter 4 connecting member 16 which is rigidly connected to a trained as an upper punch tool part 18 and together with this within a frame 20 up and down is movable.
  • a further tool part 24 Arranged opposite the tool part 18, in another base body 22, is a further tool part 24 designed as a lower punch.
  • a feed device 28 To feed the tool with initially formed as a flat sheet crimp connection components 20 is a feed device 28 which moves a belt 30 with the Crimpanschlußbau former 26 by means of a movably driven lever 32 gradually forward.
  • a Crimpanschlußbauteil 26 is disposed on the lower tool part 24, between the tool parts 18 and 24 an unillustrated cable end is arranged with stripped conductor wires and fixedly connected by crimping with the Crimpanschlußbauteil 26.
  • the force K applied to the tool by the adapter 4 is measured by means of the load cell connected via the line 10 and the path traveled by the adapter 4 (a corresponding displacement sensor is not shown), the force shown by dashed lines in FIG -way characteristic.
  • This force-displacement characteristic first passes through a preparation phase I within which the upper tool part 18 comes into firm contact with the Crimpanschlußbauteil 26 and the cable end, and then passes through the actual Vercrimpungsphase II.
  • the curve is specific for each type of Crimpanschlußbau former and cables and the tool.
  • the actual measurement evaluation takes place to suppress disturbances above a threshold force K S.
  • the dotted curve S indicates a setpoint curve, which represents a perfect crimping.
  • As a setpoint for detecting a perfect crimping curve S itself can be taken or integrated under the curve S surface F, which is a measure of the Crimparbeit done.
  • the data representing the curve S and / or the surface F are stored as desired data by the data processing device provided in the crimping device 2.
  • FIG. 4 shows a cross section through a provided with a Crimpanschlußbauteil cable, cut in the stripped wires.
  • the crimp connection component 26 is bent overall in the form of a sleeve and clamps the cores 32 of the cable in a form-fitting manner in its interior for secure contacting.
  • the tool 14 is provided with a data carrier 36, which is attached to the frame 20 in the example shown.
  • the task and function of this volume 36 is as follows: When the tool 14 is first inserted in the crimping device 2, the setpoint data, for example based on the setpoint curve S and / or the integral F, are determined and stored by the data processing device 15 in the crimping device 2, so that they are available as setpoint values for future crimping operations.
  • a crimp connection is tested for mechanical strength, electrical resistance and optical quality, and the measurement data of the crimp connection, which has been tested as faultless, is stored as setpoint data in the data processing of the crimping device.
  • the desired data of the tool 14 are read from the memory of the data processing device 15 of the crimping device 2 and read into the data carrier 36. In this way, the tool 14 itself carries its specific target data. Furthermore, upon removal of the tool 14, the number of crimp connections made with it can be read into its data carrier 36.
  • FIG. 5 shows a data carrier 36 which is inserted into a recess 38 of the frame 20 and has a base plate 40 fastened to the bottom of the recess, on which the actual data carrier is mounted.
  • the data carrier 36 is mounted protected on the frame 20.
  • the data carrier 36 may be a simple read / write memory which has a mechanically contactable or non-contact readable and readable interface with which data can be read in and out by means of a handheld device.
  • the data carrier 36 may include a complete microprocessor with program memory, data memory and input and output device, for example with antenna and transponder.
  • the data processing device 15 of the crimping device 2 accordingly has an input and output unit with which the data can be transmitted, for example, by means of a handheld device.

It is understood that in this case, advantageously, the entire disk 36 is disposed on the back of the frame 20 via the interfaces automatically when you insert or start up a tool 14 and when removing or decommissioning the tool. It is further understood that a variety of transmission techniques (with contacts, contactless with ultrasound, infrared, antenna with transmitter, etc.) can be applied.
  • the invention provides a way to monitor without loss of time and extremely safe the quality of crimp connections made with different tools, with the state of the tools can be detected even predictable.
  • the tool-specific desired data stored on the tool itself relate not only to the tool itself, but preferably also to the crimped terminal component and the cable for which the tool is to be used. They do not or only slightly depend on the particular crimping device and may, if necessary, contain a corresponding additional parameter.
  • the invention is applicable wherever multiple tools with tool-specific data used for quality control or for controlling a device operating with the tool are alternately used in one or more devices.
