Definitions
- the invention relates to a method and a device to control the connection of a contact with a conductor serving crimping process in which a Crimping tool of a crimping press from an initial position in a crimping position and then in a final position is movable.
- a disadvantage of this known device is that although there is an encoder and a height sensor, only a relatively imprecise statement about the crimp quality is feasible because of external influences and elasticities or stiffness of the mechanical drive elements be taken into account.
- the invention seeks to remedy this.
- the invention as characterized in claim 1, solves the problem to avoid the disadvantages of the known device and to create a procedure and an arrangement in which and in which the crimp quality of a crimp connection improves can be.
- the advantages achieved by the invention are in essential to see in the fact that when processing different crimp contacts with different Tool strokes no need to change the crimping press.
- the crimp height or the crimp stroke is adjustable.
- the control of the crimping press knows the exact time at all times Tool position, with which a simple evaluation of the Crimp force versus crimp stroke is feasible and others on Machines involved in the crimping process can be synchronized can.
- the crimping press according to the invention works with two Measuring systems by means of which the drive is regulated Position or a crimp height control can be realized. On rotary measuring system is with a linear measuring system coupled.
- the rotary measuring system allows a high one Positioning dynamics because of no dead times caused by There is play in the gearbox, levers or slide.
- the linear measuring system enables a precise Crimpnchnregelung. Mechanical deviations of the Crimping press, for example, by the crimping force or can open due to temperature fluctuations the crimp height control is compensated.
- the crimp height control moves the eccentric of the crimping press at most in an angular range between 0 ° and 180 °.
- the Crimp press stops at bottom dead center and reverses subsequently. Upper and lower dead center can be within this angular range depending on the crimping tool and Crimp contact can be approached as desired. intermediate positions are also possible. To realize these features is only a controlled axis is necessary.
- the sled lift or the Crimp height is programmable.
- the course of the Crimping force can be precisely represented in function of the crimping stroke and usable for quality control.

- Fig. 6 shows schematically the eccentric movement and the Carriage movement for a stroke H of, for example, 40 mm, whereby the eccentric pin 7 of 0 ° (top Start position or top dead center) to 180 ° (bottom Stop position or bottom dead center) rotates and back again to 0 °, the path between 180 ° and 360 ° not is driven through. Starting positions deviating from 0 ° as well Intermediate stops (split cycle) on the way between 0 ° and 180 ° are also possible. 180 ° of the eccentric pin 7 corresponds to the minimum crimp height (small crimp contacts with small wire cross sections). So a readjustment is possible, the crimp should be before 180 °.
- the Reversal point can be before 180 °, which is then the maximum Crimp height corresponds to (large crimp contacts with large Wire cross-sections).
