  • the clamping force for the particular type of hose clamps can not be brought about by such a worm drive but by means of a plastic deformation produced by a pressing tongs according to the invention.
  • hose clamps is used, for example, in the automotive sector, for example for fixing an axle collar on an axle shaft via a plastically deformed hose clamp.
  • the clamping force in this case determines a sealing force between the sleeve and the axle shaft and a holding force or fixing force.
  • Another field of application of such hose clamps is, for example, the "white goods" with all products in which a hose must be clamped onto a nozzle to produce a sealing effect.
  • the maximum pressing force during pressing of a workpiece by means of a pressing tool by the applied operating force for example, manually applied to the hand lever of a pressing tongs applied hand forces or the force of an actuator in a pressing machine.
  • the extent of pressing a workpiece by means of a manually operated pressing tongs is thus dependent on the skills and a reproducible, sensitive operation of the user on the hands.
  • the reproducible pressing of a workpiece with a predetermined set pressing force by means of an actuator of a pressing machine requires the use of sensors for detecting the pressing force during the pressing stroke and / or a control or regulation of the actuation by the actuator.
  • DE 42 41 971 C1 discloses a hydraulic crimping tool according to the preamble of independent claim 1, in which the hydraulic pressure used to actuate the crimping tool is monitored by means of a pressure sensor. Upon reaching a predetermined limit value, a drive motor for a pump, which generates the hydraulic pressure, switched off, whereby ultimately the pressing force of the pressing tool is specified.
  • a pressure relief or pressure relief valve may be present, which limits the hydraulic pressure and thus the pressing force.
  • DE 101 40 270 B4 discloses a manually operated crimping tool for pressing a plurality of notches on the circumference of a contact element.

  • the action of the compression springs and thus the distance of the two hand lever parts changed.
  • each of the hand lever parts associated contact elements come to rest against each other, whereby the pressure springs acting on the degree of freedom of the two hand lever parts is eliminated.
  • the contact of the two contact elements leads to the closing of a circuit, whereby the vibration of a vibrator is triggered to signal the user that the desired pressing force is reached.
  • this electric pressing force limiting device does not lead to a limitation of the predetermined desired pressing force, since the user is not prevented, despite vibrating vibrator bring about a further increase in the pressing force.
  • the relative position of said contact elements on the hand lever parts is adjustable, whereby the target pressing force for which the vibration of the vibrator is triggered, is adjustable.
  • US 5,129,350 discloses a pressing tool in which the pressing force is generated via the rotation of a spindle via a spoke-like hand wheel.
  • a mechanical pressing force indicator is activated. This consists in a display pin, which is released upon reaching the desired pressing force, so that it can be pushed out by a spring from a housing of the pressing tool.
  • the indicator pin is visible to the user, which should serve as an indication of the achievement of the desired pressing force.
  • the desired pressing force, for which the indicator pin is released is adjustable here.
  • the indicator pin is pushed so far out of the housing, that it engages in the plane of rotation of a spoke of the operating wheel, so that after a further rotation of the actuating wheel and an increase in the pressing force on the desired pressing force beyond a movement the operating wheel can be blocked.
  • US 4,947,672 A discloses a pressing tool with a hydraulic pressing force limiting device.
  • FR 2 317 051 A1 discloses a pressing tongs in which a hand lever is formed with two hand lever parts, which are coupled together via a hinge. A relative pivoting of the two hand lever parts to each other is limited by the playful receiving a mounted on a hand lever part pin in a bore of the other hand lever part with a larger diameter. For a rotational angle at which the pin rests on one side of the bore, the relative angle of rotation of the hand lever parts is secured by a spring-loaded latching device. If a sufficiently large actuating force is applied to the hand lever, the latching device is released, whereby a relative movement of the hand lever parts is made possible until the pin comes to rest on the opposite wall of the bore.
