Definitions
- Energy-saving piston-cylinder unit (working cylinder), in particular for use in the bodywork of the automotive industry
- the invention relates to an energy-saving piston-cylinder unit (working cylinder), in particular for use in the bodywork of the automotive industry.
- Interchangeable tool parts for example conically tapering mandrels or the like, can be arranged on the free end emerging from the housing.
- the tensile and shear forces exerted on the respective cylinder mandrel are limited by the force that can be applied by the respective pressure-effective area on the piston and by the fluid pressure.
- the fluid pressure in particular pneumatic pressure, is limited and can not be changed at the individual workstations in the bodywork of the automotive industry usually.
- the construction dimensions of the piston-cylinder units, which drive the push rod in the prior art directly, are also limited by design.
- a device of this type is previously known from DE 20 2007 017 274.5, which is based on the applicant.
- This device has a centering mandrel, which is connected via a toggle joint assembly with the piston rod.
- the invention has for its object to provide an energy-saving piston-cylinder unit (working cylinder), in particular for use in the bodywork of the automotive industry. Furthermore, the invention has for its object to provide an inventive use (application) of such a working cylinder.
- the piston is acted upon by the same fluid pressure during extension of the piston rod, wherein, however, the amount of fluid in the cylinder annulus is forced back into the system, for example in the opposite cylinder chamber, so that only replaces the respective volume of the piston rod by a corresponding amount of fluid needs to be.
- the result is energy saving for fluid production, in particular for the production of compressed air, which is available for example in production lines of the body shop of the automotive industry everywhere. As a result, even when flowing out a much smaller amount of fluid into the environment.
- the piston and thus the piston rod can be locked in the respective position by a valve, so that even in case of power failure of the piston and so that the piston rod can not move unintentionally, for example, when putting a load such as a body. Therefore, such cylinders can be used with advantage in so-called Stiftziehzylindern as they go into the bodywork of the automotive industry for positioning and alignment of sheet-metal components for use.
- Claim 2 describes an energy-saving cylinder, in which a controlled check valve is associated with a so-called shuttle valve having two shut-off positions, which are alternately effective during retraction and extension of the piston and the piston rod.
- the controlled check valve and the shuttle valve are arranged in the bottom of the working cylinder, so that there is a compact design.
- This floor can be designed as a bottom cover - claim 4 -, in which also suitable channels or lines and the control lines for the controlled check valve are arranged so that there are no external lines that could be damaged.
- the controlled check valve and the shuttle valve with the associated channels and lines can be arranged in a removable and to be connected to the cylinder by pressure medium pressure lid - Claim 5.
- a channel can be arranged in a housing wall. This channel leads to the cylinder annulus and simultaneously connects via other lines or channels the cylinder annulus with the controlled check valve and this also the feed cylinder space, depending on the position of the valves.
- the working cylinder according to the invention can be used with advantage in so-called pin cylinder devices, as already described above.
- considerable forces can be expended, in particular when retracting the piston rod and thus the centering mandrel, depending on how suitable the sheet-shaped components are arranged with their openings or holes through which engages the centering mandrel with the piston rod to position and center these components.
- Claim 8 describes an advantageous embodiment of the use.
- Fig. 1 is an energy-saving piston-cylinder unit (working cylinder) in
- Fig. 2 shows the device of FIG. 1 in a retracted state.
- the reference numeral 1 denotes a housing in which a cylinder 2 is arranged, in which a by fluid pressure, for. B. by compressed air, in the direction X or Y, that is longitudinally displaceable and sealed by a sealing member 3 guided piston 4, is arranged.
- the piston 4 is functionally or materially integrally connected to a piston rod 5, which may be connected to the piston 4 by screw or the like. If necessary, the piston rod 5 can also be designed in several parts (not shown), for example consisting of nested or screwed individual parts.
- the piston rod 5 carries at its outer end portion a centering pin 6, which is connected to the piston rod 5 by screw or the like functionally or materially in one piece, connected.
- the centering pin 6 can be arranged interchangeable.
- Reference numeral 7 denotes a sealing element which seals the piston rod 5 against the housing 1 in a fluid-tight manner.
- the piston 4 divides the cylinder 2 into a feed cylinder space 8 and a return stroke or cylinder annulus 9.
- a channel or a conduit 10 and 11 are each connected, which serve the Fluidzu- or - discharge.
- a hydraulic or pneumatic medium in the bodywork of the automotive industry preferably compressed air, come into consideration, since compressed air in the automotive industry is available everywhere.
- 12 is a controlled check valve and 13 denotes a shuttle valve.
- the shuttle valve 13 has two different shut-off positions, which it can optionally assume.
- the check valve 12 is connected to the conduit 14. At the same time, the valve 12 is fluid-conductively connected via a control line 16 to the channel or line 15 and via a channel or line 17 to the shuttle valve 13. The line 14 is also connected via a channel or a line 18 to the shuttle valve 13.
- the two valves 12 and 13 with the various lines, such. B. 11, 16, 17 and 18 are arranged in a bottom part 19 of the housing 1.
- This bottom part 19 can also be designed as a removable and pressure-tight seal with the housing 1, in particular with the cylinder 2, connected bottom cover (not shown).
- suitable sealing elements can be provided in order to seal the relevant parts, fluid-tight, in particular compressed air-tight.
- the apparent from the drawing device is compact, since the various channels and lines are arranged with the valves 12 and 13 in the outer contour lines of the housing 1 and thus do not increase the dimensions thereof.
- piston rod 5 is to be moved in the direction Y, ie extended. Fluid is then supplied under pressure, for example compressed air, via the line, wherein the fluid pressure propagates via the controlled check valve 12 and the channel 11 into the feed cylinder space 8 and acts on the piston 4.
- pressure for example compressed air
- fluid for example compressed air
- the fluid pressure controls the shuttle valve 13 in accordance with and via the control line 16, the controlled check valve 12 in the open position, so that the located in the feed cylinder chamber 8 amount of fluid can escape via line 11.
- check valve 12 and the shuttle valve 13 are controlled by the fluid pressure in the illustrated embodiment, it is also possible to form these valves as remotely controlled valves.
- the features described in the summary, in the patent claims and in the description and apparent from the drawing features, both individually and in any combination for the realization of the invention may be essential.
