Definitions
- the present invention relates to a device for the pneumatic actuation of 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 particularly known in the automotive industry, where these pliers are used for clamping clamping rings when assembling hoses, bellows etc. on connecting pieces, cardan shafts and the like.
- German utility model 89 00 250.4 describes a similar pressure medium pliers in which a plurality of drive pistons arranged in series are provided for increasing the thrust, the piston rod of each individual piston being guided in a cylinder wall.
- Several pressure medium pliers arranged in series with pressure pistons are also described in DE 195 19 543 and G 295 09 976.
- Thrust has long been known, as described, for example, in European patent EP 0 997 647 and German utility model DE-GM 91 11 366.0.
- the conversion of the translational force, in particular in the case of pneumatic pliers, such as, for example, the pressure medium pliers mentioned above, into an arc-shaped force takes place in the pliers head by means of a feed tool, such as a wedge.
- the Compression force on the jaws depends, among other things, on the thrust of the feed tool.
- the object is achieved by means of a device according to the wording of claim 1.
- a device for the pneumatic actuation of a pressurized tool, such as in particular pneumatic pliers, comprising a cylinder with one or more pneumatically operated, non-positive pistons arranged in series to generate a translatory force, the respective piston rods of which are held in a guide ring or a cylinder wall and are guided and a feed element operatively connected to the piston or pistons for the actuation of the tool. It is proposed according to the invention that at least two rings are arranged around the circumference of the outer circumference of the piston or pistons against the inner wall of the cylinder tube.
- At least one of the rings is a piston guide band.
- At least one of the rings is a so-called lip seal.
- Lip seals have lower static friction and lower dynamic friction.
- 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. Ultimately, these measures contribute to the freedom from maintenance of the device according to the invention.
- the previous piston is guided in the follower piston and by means of a sealing element, e.g. an O-ring, sealed.
- a sealing element e.g. an O-ring
- the device according to the invention is particularly suitable for pneumatic pliers for arranging, pressing or clamping clamping rings, bolts, cable lugs, clips and the like.
- the great advantage of the device according to the invention is that the translational thrust remains constant at the same pneumatic pressure. However, this also results in constant pressing forces with identical pliers and with the same pneumatic pressure. Finally, the pressing forces remain constant over the entire life of the device proposed according to the invention.
- the device according to the invention can also be used universally for the actuation of pneumatic tools.
- the present invention is not limited to clamping tools, but can be used for any tools that can be operated by pneumatically operated feed elements that can be actuated by means of the translational thrust force.
- Fig. 1 in longitudinal section, a pneumatic pliers designed according to the invention, and
- Fig. 1 shows in longitudinal section a pneumatically operated and pressure-driven pliers 1 for the installation of pipe clamps, hose clamps, clamping rings etc.
- a plurality of pistons 5 arranged in series or in series are arranged.
- the advantage of these pistons arranged in a row is an increase in force, since the translational force that can be generated is significantly higher than when only a single piston is used.
- One reason for this is the increased piston area.
- connection 8 is provided for connecting the pliers to a pressure medium, such as compressed air, the pressure medium supply being able to be opened or vented by means of a valve lever 7 for the operation of a valve 9 " individual pistons 5 have a passage 10 for the passage of the pressure medium through the piston rods 6.
- outlet openings 11 are provided radially outward, for the discharge of the compressed air and for the actuation of the next one in the direction of the pliers tool Piston 5.
- the next piston 6 is driven forward by the compressed air, and the passage of the compressed air through the passage of the next piston rod is repeated in an analogous manner.
- each piston with its associated cylinder cover 13 represents a fluidic unit.
- the pliers head 38 is preferably exchangeably connected to the cylinder 3 by means of a union nut 43.
- the jaws 36 are laterally protected against contact (accident protection) or contamination by cover plates 46.
- the piston 5 has a piston seal 22 and a piston guide band 23 in the direction of the cylinder tube wall 3.
- the piston seal 22 is preferably a so-called lip seal.
- the use of lip seals in particular results in low static friction and low dynamic friction.
- the piston guide band 23 avoids touching the piston on the cylinder tube and thus contributes to the smooth running property of the pistons and furthermore leads to the maintenance-free 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 is sealed against the cylinder cover 13.
- the piston rod 6 extends further into the piston head 12 and has an additional seal 25 in the edge region of the front end, such as a so-called O-tube. This measure leads to constant translational thrust at the same pneumatic pressure.
- FIGS. 1 and 2 are of course only an example which is intended to serve to better explain the present invention.
- the invention is in no way limited to a pneumatic pliers, shown in FIGS. 1 and 2, but relates to any pneumatically actuated, pressure-driven tools, which a pressure cylinder tube with one or more pneumatically operable, non-positive piston arranged in series for Generate the translational force, as described according to the invention. 1 and 2, particular importance was attached to the presentation of the features essential to the invention, and all features, structural parts and the like known per se from the prior art for devices of the type described are corresponding to the features essential to the invention in any manner and Can be combined in different ways.
- the further configuration of the device according to the invention should not be dealt with at this point, such as electronic control, the attachment of monitoring sensors, the automated operation of the device according to the invention, the choice of material for the inventive direction, be it steel, aluminum or possibly the use of reinforced polymer materials etc.
- the in the Fig. 1 and 2 device can be replaced by changing the in Fig. 1 pliers tool can be used as any other pressure-operated tool, such as a drilling tool, punching tool, screwing tool, etc.
- piston seal between piston 5 and cylinder 3
- piston guide band for guidance
