Definitions

  • the invention relates to a hydraulic handheld device according to the features of Preamble of claim 1.
  • Such hydraulic hand tools are already in different Embodiments have become known.
  • Such a trained Handheld device can not only be used as a portable punching device, for example for punching of holes in sheet metal plates, but can, with more special Design, such as use as a blind riveter. Regarding The latter is based, for example, on a prior art according to EP B1 62 206 directed.
  • DE-A-19512 594 is a hydraulic handheld device a push / pull device known in the form of a punching device, with a hydraulic piston movable relative to a cylinder housing, a Counterholder and an anchoring device for the punch, in which the anchoring device is firmly connected to the cylinder housing and the counter-holder part by the hydraulic piston relative to the anchoring device is movable.
  • the arrangement of the counter holder surface is still not considered satisfactory.
  • the invention deals with the technical Problem, the well-known hydraulic handheld device, in particular constructively, improve and to simplify as much as possible.
  • the device can also be more compact be formed.
  • the counterhold in is essentially annular.
  • the anchoring device can, so far, also agree with the known design, central to the counter holder be arranged. Enforced according to the invention the counter-holder the anchoring device , So is the application of force in a simple way the counterholder by means of the hydraulic piston nevertheless central arrangement of the anchoring device possible.
  • the hydraulic piston can in this case Detail the anchoring means Push the push rods through, which are placed on the counter holder act. To hold the counter holder together with the Hydraulic pistons can further separate screw connections be executed.
  • the hydraulic piston at the anchoring device in his Rest position is spring-supported.
  • a simple one is enough Compression spring between the top of the hydraulic piston and the underside of the anchoring device.
  • a specific design also provides for how already mentioned basically that the hydraulic piston essentially over an entire cross-sectional area is acted upon.
  • a hydraulic handheld device 1 with a counter holder 2 and an anchoring device 3.
  • the anchoring device 3 has an internal thread 4, in which in the device according to the embodiment, one Sheet metal punch device to attach a punch.
  • the counter holder part 2 is relative to the anchoring device 3 movable, namely extendable.
  • the anchoring device 3 is fixed attached to a housing 6 of the handheld device, namely by means of a cylinder housing 25 for a hydraulic piston 5. In the embodiment via a thread 7 and locking screws 8.
  • a hydraulic reservoir in a container 11 accommodated To act on the hydraulic piston 5 is in the Handheld device 1 a hydraulic reservoir in a container 11 accommodated.
  • the loading takes place in detail driven by means of an electric motor 12 Pump plunger 13.
  • the drive takes place via a the motor shaft 14 radially attached eccentric 15.
  • the Eccentric 15 interacts with a ball bearing, whereby the inner ring 16 of the ball bearing firmly with the eccentric is connected, however, the outer ring 17 on an underside 18 of the pump plunger 13 acts.
  • the pump plunger 13 is in its lower position by a compression spring 19th biased.
  • the hydraulic piston 5 has in further detail an upper piston surface 20 which acts on the counterholder 2 pushrods 21 are supported.
  • the push rods 21 are different on a lower surface 22 of the essentially circular counter-holder 2.
  • the counter-holder is offset at an angle from the push rods 21 2 by means of mounting screws 23 firmly with the hydraulic piston 5 connected.
  • the fastening screws 23 are in detail with an annular flange 24 of the hydraulic piston connected.
  • the Ring flange 24 extends in part overlap to the cylinder housing 25, which is device-fixed is.
  • the cylinder housing 25 has a counter holder side External thread 7, by means of which the anchoring device 3 is screw-connected to the hydraulic device. Accordingly, the anchoring device 3 is on the cylinder housing side also formed like a cylinder, on the opposite side a cylinder bottom or a Bracket plate is formed.
  • the cylinder bottom is on the one hand, accessible from the outside, with an internal thread 4 having anchoring opening formed and on the other hand has the through openings 26, 27 for the push rods 21 or fastening screws 23. In this respect, this also results from the cross-sectional representation 4, to which still further below is received.
  • the embodiment are in three push rods 21 each with the same angular distribution and three fastening screws 23 are provided.
  • the Counterholder is here with an internal thread 28 Cylinder housing 25 on the counter holder side of the cylinder housing connected. Furthermore, the counter holder part 2 2 to 4 an outer, according to the embodiment of FIGS. Ceiling-like protruding cover wall 29 on the housing side out. The cover wall 29 moves in the embodiment outside on the cylinder housing 25 at a Actuation stroke of the counter holder. 3 is the actuated position shown. So is a maximum Utilization with regard to the outer diameter for reached the counter support surface.
  • FIGS. 3 to 4 is a further modification 1 or FIGS. 3 to 4 shown.
