- at least one safety valve via which the respective working flow path can be shut off, is arranged in the first working flow path and / or in the second working flow path.
- Figure 1 shows a hydraulic axis with a hydraulic control block with a generic hydraulic switching structure and two configurable, specific switching structures
- FIG. 2 shows the hydraulic control block according to FIG. 1 in a perspective, partially transparent view
- Figure 3 shows the hydraulic control block according to Figure 1 and 2 in a partially transparent
- FIG. 4 shows the hydraulic control block according to the previous figures in one
- a hydraulic axis 1 has a hydraulic control block 2 and a hydraulic machine 4 connected to it and a hydraulic cylinder 6 or 8 which is supplied with pressure medium and optionally connected to the control block 2.
- the control block 2 has a generic hydraulic switching structure.
- control block 2 contains all the necessary fixed and switchable hydraulic means, in particular components and pressure medium channels, in order to be able to configure several specific switching structures.
- a respective switching structure A, E is a specific hydraulic cylinder 6
- hydraulic cylinder 6 has two working connections and the optionally shown hydraulic cylinder 8 has three working connections.
- Each working connection has a specific piston area or a specific working space of the respective one Hydraulic cylinder 6, 8 fluidly connectable.
- Two different types of hydraulic cylinders can be connected to switching structure A (B) (synchronous / differential).
- control block 2 has a first supply interface 10, from which a first working flow path 12 originates, and a second supply interface 14, from which a second working flow path 16 originates.
- the supply interfaces 10, 14 are designed as supply connections. Alternatively, they can be designed as openings in the control block 2 or the like.
- a high-pressure and low-pressure side of the is fluidically connected to them
- the first supply connection 10 can be fluidically connected to the high pressure side and the second supply connection 14 to the low pressure side, or vice versa.
- the former is the case.
- the first working flow path 12 has a branch 18 at which a third
- Working flow path 20 branches off.
- a valve 22 which is designed as a 2/2-way switching valve, is arranged.
- the first working flow path 12 extends further, a filter 24 being arranged in it.
- a filter 24 being arranged in it.
- two series-connected safety valves 26 are arranged, via which the first working flow path 12 can be shut off in redundancy. They are too
- a shut-off valve 32 is arranged, via which the second working flow path 16 can be blocked. Starting from the second supply connection 14, via the shut-off valve 32, the second working flow path 16 continues up to one Branch 34 continues. Two second working connections 36A, 36E branch off from it, each on different sides of the control block 2.
- the third working flow path 20 continues beyond the valve 22, up to a branch 38, from which only a third working port 40E branches off to that side of the control block 2 where the ports 30E and 36E belonging to the specific circuit or configuration E are already provided.
- the hydraulic cylinder 6 with two piston surfaces or the hydraulic cylinder 8 with three piston surfaces can optionally be supplied via the control block 2, depending on the configuration.
- a connecting flow path 42 is provided, via the first
- Working flow path 12 is fluidly connectable to the third working flow path 20 downstream of the valve 22.
- a receptacle 44E is provided in the connecting flow path 42.
- a receptacle 44A configured identically in the exemplary embodiment is in the first
- a closure means 46 designed as a screw, in particular M18 x 1.5 (in this case according to DIN906) can be inserted or inserted into the respective receptacle 44E, 44A.
- Closure means 46 can be inserted into the corresponding receptacle 44E, 44A.
- the closure means 46 is inserted into the receptacle 44A, whereby the circuit structure A is configured to supply hydraulic cylinders with two working spaces or piston surfaces at the working connections 30A, 36A. Then the working connections of the circuit structure E are 30E, 36E and 40E
- the pressure medium can therefore no longer flow directly via the first working flow path 12 to the first working connection 30A, but instead must flow via a section of the third working flow path 20, the valve 22 and the connection flow path 42 activated in this configuration A.
- the valve 22 has the function of either supplying the annular space of the hydraulic cylinder 6 supplied by the first working connection 30A with pressure medium or blocking it.
- the hydraulic control block 2 has an accumulator flow path 48 which can be fluidically connected to the respective working flow path 12, 16 via pressure limiting valves 50 preset to a pressure value.
- a gas-loaded hydraulic accumulator 52 is connected to the accumulator flow path 48.
- the hydraulic cylinder 8 which has three working spaces or piston surfaces, can be supplied with pressure medium.
- the closure means 46 is then released from the receptacle 44A and removed and inserted into the receptacle 44E.
- the working connections 30A and 36A are closed and the working connections 30E, 36E and 40E are open, the third working flow path 20 being on the part of the im
- Embodiment provided blind hole is still closed.
- outlets or working connections 30A, 30E, 36A, 36E, 40E can each be designed in the control block 2 as an individual pressure medium channel.
- Working connections can increase the variability of the control block, in particular to meet market requirements.
- pressure medium can then flow via the first working flow path 12 via the branch 18 and the filter 24 directly to the first working connection 30E and thus into the left annular space of the tandem cylinder 8. Since the connecting flow path 42 is blocked by the closure means 46 in the configuration E, this is decisive Position of the valve 22 now, as to whether the annular space which is connected to the third working connection 40E is supplied with pressure medium or not.
- the hydraulic pump delivers pressure medium from the second
- the circulation valve 54 is closed for this purpose.
- the working connections 36E and 40E are fluidly connected via the circulation valve 54 and short-circuited.
- the hydraulic pump then delivers pressure medium from the working chamber connected to the second working connection 36E to the working chamber connected to the first working connection 30E.
- the very small piston area of the piston delimiting this leads to the high travel speed.
- Circulating volume flow through the circulation valve 54.
- Hydraulic cylinder 8 matched to one another in such a way that, apart from in particular leakage-related volumes, no differential volume has to be absorbed by the hydraulic accumulator 52.
- pressure medium can flow between the working flow paths 12 and 16 via the circulation valve 54.
- the differential volume when the differential cylinder 6 is retracted, the differential volume must always be conveyed into the accumulator 52.
- the circulation valve 54 enables the differential cylinder 6 to be extended at the same speed as it is retracted with a low displacement force.
- Figures 2 and 3 show the hydraulic control block in perspective and in a partially transparent side view, the receptacles 44A and 44E being indicated. They are arranged inside the control block 2 and are accessible from the outside via mounting holes.
- the closure means 46 an M18 screw, can also be inserted via this and be removed.
- the receptacles 44A and 44E can be seen in a cross section of the control block.
- a hydraulic control block with a generic hydraulic circuit structure for a selection of possible hydraulic cylinders and for controlling the pressure medium supply of the hydraulic cylinders, which is prepared so that one of the means can be switched from one specific circuit structure to the other by rearranging one of the means.
- a hydraulic or servohydraulic axis is also disclosed therewith.
