Definitions

  • the invention relates to a hand-held tacker according to the preamble of claim 1.
  • the cooling system generates an air flow for the flow of at least the electric motor.
  • the cooling air can enter and exit the housing through suitably positioned slots.
  • the air flow can be in thermal exchange with at least one further component of the tacker, in order to also cool this component as required.
  • the component may preferably, but not necessarily, be an electrical energy store, for example a replaceable battery insert, and / or power electronics.
  • the deactivation of the electric motor can be carried out as long as required, until the engine had sufficient time to cool down. But it can also be a targeted lengthening of the possible beat frequency, so that a user of the tacker is not interrupted in his activity, but at most slowed down. With appropriate dosing of deactivated times of the engine, this slowing down can be imperceptible or at least not in a disturbing way.
  • At least parts of the cooling system are mounted Schlage coupled via an attenuator.
  • the high mechanical loads in the housing of a tacker is taken into account.
  • a possibly provided fan may be accommodated in rubber mounts so that the rubber mounts form the muffler.
  • a fan wheel arranged on a motor shaft of the electric motor is not provided.
  • Such fan wheels are widely used for permanently operated electric motors for cooling purposes.
  • these fan wheels are not very effective in Eintreibellan, since the motors run only for a short time under high load and - depending on the design of Eintreibuzes- also change their sense of rotation.
  • the provision according to the invention of a cooling system makes it possible to dispense with such a fan. In particular, the space required for the engine can be kept small thereby.
  • a mechanical energy store is designed as a tensionable spring 31, in this case a helical spring made of metal.
  • the tacker 10 has a handle 20 on which a trigger switch 19 is arranged to trigger a driving operation with the tacker 10.
  • the triggering is electromechanical, whereby a control of the device state by a control electronics before a release of the mechanical energy storage is possible in a simple manner.
  • the trigger switch 19 is connected via a switch line 57 to the control unit 23 for this purpose.
  • the electric motor 51 is connected via a control line 54 to the control unit 23 and can be put into operation via this, z. B. when a contact pressure, a pressure switch (not shown) is actuated at a mouth portion 12 or already after successful Eintreibvorgang when the tacker 10 is lifted again from a workpiece.
  • the fan 55 causes an air flow along the arrows 61, which cools not only the fan motor 56, but subsequently also the control electronics 23 and the power supply 21.
  • the air is sucked in an upper, front housing portion 50 through air slots 41.
  • An inner housing wall 22 separates the intake region from the housing region of the remaining drive arrangement 30, so that an air duct is formed, in which the electric motor 51 is arranged.
  • the sucked air is primarily first led to the electric motor 51.
  • the air is deflected by the housing wall 22 by 90 ° down, after which it flows through the interior of the handle 20 from top to bottom and the previously operated suction fan 56, 57 passes.
  • the air Downstream of the fan 56, 57, the air enters a lower extension, in which the control electronics 23 is received.
  • a lower extension In the lower end of the handle 20 and in an upper cover of the mounted under the handle power supply 21 overlapping openings 41, 42 are provided, by means of which the cooling air flows from the handle 20 into the power supply 21. After overflowing the battery cells, the cooling air then exits through an opening 44 in the housing of the power supply back to the outside.
  • the fan 56, 57 operated in the reverse direction, so that the air flow with otherwise identical design of the housing exactly the opposite way. Accordingly, first the power supply 21, then the control electronics 23 and finally the electric motor 51 is cooled here. In this reverse order, the air temperature for cooling the electric motor 51 is higher, whereas the power supply is better cooled. This may be desirable in particular for temperature-sensitive and high-quality accumulators, such as lithium-ion accumulators.
  • the engine is cooled by being deactivated upon reaching a corresponding engine condition.
  • a cooling system by deactivation of the engine may be provided as an alternative or in addition to a cooling fan 56, 57.
