Definitions

  • the present invention relates to a device for pneumatic Operating a pressurized tool according to the preamble of claim 1 and a pneumatic pliers.
  • Pneumatic pliers for pressing and clamping clamping rings, Bolts, cable lugs, clips etc. are known.
  • pneumatic pliers are known in the automotive industry, where these pliers are used for clamping clamping rings the assembly of hoses, bellows etc. on sockets, cardan shafts and the like can be used.
  • DE 37 42 782 is a pressure medium pliers for spring band clamps known, with a valve-controlled pressure medium connection and a wedge-shaped feed member.
  • the object is achieved by means of a device solved according to the wording of claim 1.
  • a device for pneumatic actuation is proposed a pressurized tool, such as one in particular pneumatic pliers, comprising a cylinder with one or several pneumatically operated, non-positive, arranged in series Pistons for generating a translatory force, their respective piston rods in a guide ring or one Cylinder wall are held and guided and one with the or the piston operatively connected feed member for actuation of the tool. It is proposed according to the invention that at least peripherally encompassing the piston or pistons two rings directed against the inside of the cylinder tube are arranged.
  • At least one of the rings has a piston guide band.
  • At least one is the rings a so-called lip seal.
  • Piston guide bands avoid touching the piston or the piston crown or plate on the cylinder and thus contribute to the smooth running properties of the piston at. Ultimately, these measures contribute to the freedom from maintenance of the device according to the invention.
  • Guaranteeing pistons the previous piston guided in the follower piston and by means of a sealing element, e.g. an O-ring, sealed.
  • the device according to the invention is particularly suitable for a pneumatic pliers for arranging, pressing or clamping of clamping rings, bolts, cable lugs, clips and the like.
  • the great advantage of the device according to the invention lies in that the translational thrust with the same pneumatic Pressure remains constant. But this also results constant pressing forces with identical pliers and with same pneumatic pressure. Ultimately, the compression forces remain over the entire life of the invention proposed device constant.
  • the inventive Device also universal for actuation usable with pneumatic tools.
  • the present invention is not restricted to clamping tools, but can be used for any tools which by pneumatically operated and by means of translatory Pushable actuable feed elements are operated can.
  • Fig. 1 shows in longitudinal section a pneumatically operated and pliers 1 which can be driven by pressure for the installation of pipe clamps, Hose clamps, clamping rings etc. in a cylinder 3 are several in series or in a row Piston 5 arranged.
  • the advantage of this arranged in series Piston lies in an increase in power by the producible translatory force is significantly higher than when used just a single piston.
  • One reason for this is the enlargement the piston surface.
  • connection 8 is provided for connecting the pliers a pressure medium, such as compressed air, the Pressure medium supply by means of a valve lever 7 for actuation of a valve 9 can be opened or vented.
  • the individual pistons 5 have a passage 10 through the piston rods 6 on, for the passage of the pressure medium.
  • the front end of the piston rods 6 are radial outward openings 11 provided for the Escape the compressed air and for actuating the in the direction Pliers tool next piston 5.
  • the next piston 6 driven forward, and the passage the compressed air through the passage of the next piston rod repeats itself in an analogous manner.
  • wedge piston 34 On the front of a wedge-shaped Feed member 35 is arranged for actuating the pliers head 38.
  • the pressure medium such as the Compressed air, forward-driven wedge 35, for example, the two pliers jaws 36 mounted in the pin 39 in the rear Area separated by the wedge surface between pushes two rollers 40.
  • the two Pliers jaws 36 driven together in the closing direction on the front, for example for clamping a clamping bracket or for pressing ear clips or the like by pressing of pliers 42.
  • the pliers head 38 is preferably by means of a union nut 43 interchangeably connected to the cylinder 3.
  • the jaws 36 laterally by means of cover plates 46 against contact (Accident protection) or pollution protected.
  • the piston 5 points in the direction of the cylinder tube wall 3 a piston seal 22 and a piston guide band 23.
  • at the piston seal 22 is preferably a so-called Lip seal.
  • the piston guide band 23 avoids touching of the piston on the cylinder tube and thus contributes to the smooth running property the piston and leads to freedom from maintenance of the pliers tool proposed according to the invention.
  • Another inventive feature is the use of a Lip seal 24, by means of which the piston rod 6 opposite the cylinder cover 13 is sealed. Further extends the piston rod 6 into and into the piston crown 12 has an additional seal in the edge area of the front end 25, such as a so-called O-tube. This Measure leads to constant translatory thrust same pneumatic pressure.
  • FIG. 2 parts analogous to FIG. 1 are the same Provide reference numerals, thereby repeating the operation the pressure medium device according to the invention is dispensed with can be.
  • FIGS. 1 and 2 it is of course only an example, which serve to better explain the present invention should.
  • the invention is in no way limited to pneumatic pliers, shown in FIGS. 1 and 2, limited, but relates on any pneumatically operated means Pressure drivable tools which have a pressure cylinder tube one or more pneumatically operated non-positive piston to generate the translatory Force, as described according to the invention.
  • FIGS. 1 and 2 particular emphasis was placed on the presentation of the features essential to the invention, and all in itself known features, structural parts and the like for devices of the type described correspondingly with the features essential to the invention in x-arbitrary Can be combined in different ways.
  • the device shown in Figs. 1 and 2 can by Replacing the pliers tool shown in Fig. 1 as any other pressure-operated tool used, such as a drilling tool, Punching tool, screwing tool etc.
