Definitions
- the present invention relates to a method and a device for Quality assurance of crimp connections on crimping devices.
- the electrical line must be from Electrical connection tightly encloses around a good power transmission ensure and also to prevent cavities that corrode being able to lead.
- the closing height of the tool in relation to the thickness of Electric line is particularly important here. If the closing height is too high, so the compound may have too low a tensile strength. Is the Closing height too low, it can lead to a termination of the strands and also in this case too low a tensile strength. The setting of the Correct crimp height is therefore an important issue in crimping devices.
- DE 43 37 796 A1 discloses a method for monitoring the quality of Crimp connections specified, in which the temporal force curves of a Plurality of reference measurements are captured as traces and a averaged measuring curve is formed, to which an upper and a lower spaced curve are created, so that therefrom a tolerance band arises.
- a crimping process to be monitored it is checked whether the off This crimping process determined entirely within the surface of the Tolerance band is. Faulty crimping can be determined by this become.
- the invention is therefore based on the object, a method for Quality assurance of crimps to create, with that too Long-term operations can be detected safely.
- the actual value becomes during the crimping operations the crimping force and / or crimp height are constantly within predetermined upper and / or lower tolerance masses of the crimping force and / or crimping height measured and after reaching a correction reading by several Measured actual values, a corrected readjustment of the crimp height carried out.
- commissioning a crimping device is at the beginning of Production start the machine temperature approximately constant. With the However, time heats the device and it is an extension of the Machine body, which is an increase in the crimp height and at the same time Reduction of the crimping force has.
- correction value a correction measure is given, which is preferred is about half of a tolerance measure. This correction reading is at the same time the mean of the measured actual values of the individual Crimps.
- the heating phase of the crimping device usually find several corrected new settings of crimp height instead. This will be as long as possible carried out until the crimping device has reached its temperature stability and the desired value of the crimp height in a predetermined minimum range is complied with.
- the apparatus for performing the method is with a via a Drive connecting rod back and forth offset movable die part and a fixed die part with a device for pressing height adjustment Mistake. It is characterized by the fact that the drive connecting rod with a in this case in its longitudinal direction displaceable die part and with a die Displacement causing adjusting drive for fine adjustment of the pressing height is provided, wherein the adjusting drive via a comparative target lst control is controlled.
- the actual value of the control is determined by an actual value detector attached to the adjusting drive tapped.
- the setpoint can be at the control unit of Device can be adjusted or even from a calculated Reference size of the Crimpkraftwait be specified.
- the target value The regulation is then about the force curve during the crimping process determined.
- a comparator is provided, in which the desired value from control unit or the crimp force during the crimping process is stored.
- the adjustment consists of a stepper motor and a gearbox.
- the adjusting element itself is a perpendicular to the Direction of movement of the drive connecting rod in a hole located therein inserted eccentric pin.
- the axis of rotation of the eccentric pin is with the Is-Wertermittler connected, which indicates the position value of the eccentric pin transmitted the comparator.
- the adjustment accuracy of the eccentric pin is 0.002 mm.
- the actual value of the Crimpkraftverlaufs is throughout the Crimping process measured and with the predetermined in the comparator Target value of the Crimpkraftverlaufs compared. In case of deviations between the Actual and the desired value, a correction of the Crimpkraftverlaufs to the target value, by changing the pressing height.
- the method is as it takes place in a production process shown schematically.
- X the target amount of the crimp height H is designated. On the time axis Z this is a straight line.
- X1 the lower one Tolerance measure of the crimp height H and with X2 the upper tolerance of the Crimp height H is called.
- the within this tolerance dimensions X1 or X2 produced crimp are qualitatively not too objectionable.
- the production process is divided into phases 1 to 6. In the Phase 1 after commissioning of the crimping device is the Device temperature approximately constant. The actual values of the crimp height H are not drawn here and move in a narrow Tolerance range around the nominal dimension X.
- phase 2 a first warming occurs and thus also extension of the device body instead of what a Increasing the crimp height H leads.
- the actual values l of the individual Crimping processes tend to look down on the graph, that is for a higher crimp height H or a lower crimp force.
- the correction reading Y represents an average value several measured actual values 1. This correction measured value Y amounts to about half of a tolerance measure, as here the tolerance X2.
- phase 2 can be repeated several times, and while until the crimping device has reached its operating temperature and a Process stability is given, as shown in the phase 6.
- the Heating E of the crimping device in the present example comprises the Phases 2 to 5.
- the temperature stability T has occurred.
- the entire production process P consequently comprises Phase 1 with approximately constant Temperature of the crimping, the phases 2 to 5 the area E in the Heating of the crimping takes place and the phase 6 at the Crimping device their operating temperature T and thus their process stability has reached.
- the means for pressing height adjustment is shown as to a device for carrying out the method is used.
- the Device consists essentially of the drive rod 11, the Die part 10, the adjustment 14 and the comparative set / lst control 15.
- the drive connecting rod 11 is driven by the eccentric 30. Of the Eccentric itself gets its drive via the shaft 31.
- the die part 10 is held in the guide 32 and is slidable in its longitudinal direction.
- the tool holder 33 is attached.
- the underlying second tool part is omitted.
- the pressing height H is the distance between these two tool parts when open Tool.
- the bore 17 is included, in which the adjusting member 12 is inserted.
- the adjusting member 12 simultaneously represents the Connection between the drive connecting rod 11 and the die part 10.
- the adjusting member 12 Im Area of the bore 17 of the drive connecting rod 11, the adjusting member 12 as Eccentric bolt 18 is formed.
- the adjusting member 12 is connected to the adjustment 14, which is driven by the stepping motor 20. Between connected is the transmission 21.
- the axis of rotation 22 of the Eccentric pin 18 is connected to an actual launcher 23, which the Position value of the eccentric pin 18 is transmitted to the comparator 24.
- the Comparator 24 In the Comparator 24 is the setpoint value X of the crimp height H from the control console via the line 26 entered.
- the comparator 24 compares the actual values 1, with the setpoint value X and indicates corresponding control signals via the line 27 the stepper motor 20. At the same time the comparator 24 via the line 28th the actual value 1 entered by the Crimpkrafttechnikwachung, so that the Crimping force can be used for the regulation of the device.
