Definitions

  • the invention relates to a tool assembly according to the preamble of claim 1.
  • a hand tool of the type described above, but without Control switch and control line and only with one connection for one Pressure hose is known from DE-PS 21 36 742. This well known Tool can only be used with an external control switch.
  • the hand tools described above include examples Crimping pliers and pushing pliers used to connect pipe ends with the interposition of coupling pieces that serve from a sleeve and two sleeve-shaped parts, between which the Pipe ends are positively and absolutely tight have to.
  • Crimping pliers and pushing pliers used to connect pipe ends with the interposition of coupling pieces that serve from a sleeve and two sleeve-shaped parts, between which the Pipe ends are positively and absolutely tight have to.
  • Commercial clutch units are developed, which are divided into two groups have it divided.
  • DE 42 07 764 A1 is a generic tool assembly known, in which an electric motor, a hydraulic pump, a hydraulic cylinder and a switch integrated are. This makes the device very heavy, especially when when high hydraulic power as when pressing pipes be requested and the operator has the whole Carrying weight with your hands and in the required Bring work positions, i.e. possibly in a unfavorable location below a ceiling. The ratios would deteriorate even further if in such a device also integrated a power storage would.
  • the invention is therefore based on the object of a tool assembly Specify the type described above, in which the hand tool reliable, before, during and after the machining process can be held without fatigue with both hands, so that a more precise Tool use is made possible.
  • the subject of the invention ensures that the operator does not wait until after one control switch lying around or hanging around, but finds this in the grip area of the hand tool itself.
  • the subject of the invention is therefore not only the hydraulic hand tool via a pressure hose, but also via a control line with the hydraulic pump and its control devices connected and has thus even the smallest possible weight.
  • the operator cannot only use the tool with regard to the perform the required work carefully and accurately and about the The duration of the work process also last, but still more Manipulate the tool yourself, if this is the case with certain Tool types should be required.
  • the handling is also there largely fatigue-free, although most are hydraulically driven Tools have a considerable weight.
  • the hand tool has at least one Has grip surface and when the control switch is so close to the Grip surface is integrated in the hand tool that he without letting go of the Grip surface is actuated.
  • hydraulic pump its electric Drive motor and a rechargeable power source in a portable case are built in, that with holding devices for fastening on the back is provided to an operator.
  • the hydraulic drive in this way is designed so that the portable, via a rechargeable power source driven hydraulic pump and the Deformation properties of the line connection of the pressing process in a maximum of 6 seconds, preferably in a maximum of 4 seconds.
  • the tool assembly consists of a hand tool 1 and a portable case 2 in which a rechargeable power source 3, a Pump sump 4, a hydraulic pump 5 and a drive Electric motor 6 are arranged.
  • the electric motor 6 is in accordance Control fed by the current source 3.
  • the housing 2 is on his an end face with a connecting piece 7 for a coupling 8 a Pressure hose 9 and with a connector 10 for the connection a clutch 11 a control line 12 is provided.
  • the housing 2 has a handle 13 and holding devices not shown here for Attach to the back of an operator.
  • the hand tool 1 consists of a so-called basic device 14 and an interchangeably attachable tool head 15
  • Basic device 14 includes a housing 16 with a handle 17 that opens its circumference forms a gripping surface 18.
  • an electrical control switch 19 in housing 16 arranged, which is connected to the control line 12.
  • Gland screw connection 20 for moisture-proof implementation of the control line 12 is used Gland screw connection 20.
  • a hydraulic drive 21 which consists of a hydraulic cylinder 22 with a piston 23, piston rings 24 and one Piston rod 25 is made.
  • the hydraulic cylinder 22 is in the housing 16 screwed in and fixed by a lock nut 26.
  • a compression spring 27 which is partially from the Piston rod 25 is partially guided by a guide sleeve 28.
  • On the End of the hydraulic cylinder 22 is also an intermediate piece 29 with a Screwed flange part 30, the one in a coaxial bore Bearing ring 31 for the piston rod 25 carries.
  • flange part 30 With said flange part 30 is a plurality of screws 32, of which only one is visible, the already mentioned tool head 15 connected which a press jaw housing 33 belongs to, which has a further flange part 34 is provided.
  • a Cross head 35 Inside the press jaw housing 33 is a Cross head 35 with two control rollers 36, of which because of the chosen Only the top cut is visible.
  • the two steering roles are open parallel pins 37 stored, the ends of which in turn Cross head 35 are set.
  • the cross head 35 stands with the piston rod 25 in the manner shown and is driven by this.
  • the press jaw housing 33 consists of two bowl-shaped halves are held together by a screw 38.
  • the press jaw housing 33 is fork-shaped and with a diametrically continuous recess 39 provided in the two Double-armed press jaws 40 and 41 partially protrude.
  • the press jaws 40 and 41 are on two parallel pivot pins 42 and 43 and are supported by a compression spring 44 in the shown kept stable.
  • the pivot pins 42 and 43 are at the end of the Press jaw housing 33 stored.
  • a pliers mouth 45 to radial pressing so-called line connector is used.
  • the Control switch 19 actuates the hydraulic pump via the control line 12 5 puts into operation, so that the piston 23 under the pressure hose 9 Pressure is set and shifted to the right.
  • This piston movement follow the control rollers 36, which in this case run onto two control surfaces 48, only the upper one is visible.
  • the control surfaces 48 have in relation to the tool axis A-A the effect of inclined planes, i.e. under the action of the control rollers 36 and the control surfaces 48 Forceps jaw 45 closed with great force and the pressing process carried out. This serves - after releasing the grip surfaces 46 and 47 - the outer surface of the die housing 33 as another Grip area to hold the tool reliably in the selected position to be able to. In other words, the operator has both hands on Hand tool 1.
  • the press jaws 40 and 41 are together with the pivot pins 42 and 43 exchangeable as a structural unit and for this purpose by means of a tab 49 and a cylinder pin 50 held in the press jaw housing 33. After this Loosening the cylinder pin 50, it is easy to remove the outer Part of the tool head 15 and replace by a set of Press jaws with a jaw 45 different diameters or to replace differently shaped pressing surfaces.
  • Tool assembly is an easily transportable tool with which Cable connections made reliably, quickly and with little effort can be.
