Definitions

  • the invention relates to a control block with logic valves according to the preamble of patent claim 1.
  • Such control blocks are used, for example, for controlling hydraulic cylinders, wherein for controlling the pressure medium flow to and from the hydraulic cylinder logic valves - or according to DIN standard: 2-way cartridge valves - are used.
  • Such logic valves - also called logic - can take on a path, current and / or pressure function and, at high flow rates, for cost reduction instead of conventional conventional elements, i. Wegschieber-, barrier, pressure and flow control valves used.
  • To retract and extend a cylinder for example, at least 4 logic valves are required, via which each pressure chamber can be connected to the pump (pump logic) or to the tank (tank logic).
  • the invention has for its object to provide a control block with logic valves, which can be produced in a simple manner.
  • control block is designed with a basic block on which at least one pressure connection and a tank or return connection are formed.
  • the logic valves are attached to the base block via one or more block disks, the associated load port being formed on each block disk and each block disk carrying at least pump logic and tank logic.
  • Such a control block can be produced in an extremely simple manner, since the pressure and tank channels can be easily formed in the base block and the connection to the block discs can be produced by short connection channels, which can be introduced already during the casting process or subsequently by drilling. Since the consumer connections are each formed on a block disc, the connection-side piping is much simpler than in the conventional monoblock construction.
  • the basic block can be in principle manufacture as a cast block and can be cut off from this ingot as needed, ie according to the number of block slices to be used, so that the delivery time of individually adapted solutions compared to the conventional solutions, in each case a separate new cast construction was required, can be significantly shortened.
  • the control block according to the invention is preferably used for controlling a differential cylinder (but also different kind of consumer), wherein both the piston-side cylinder chamber and the piston rod side annular space is associated with a respective block disk, each with a tank and pump logic.
  • the construction of the basic block is particularly simple if the tank and pump channels run parallel and the corresponding connections open at the front.
  • the amount through the two pump logic is always the same regardless of the direction of movement of the differential cylinder.
  • pressure medium supply into the cylinder chamber only half the amount of pressure medium is displaced according to the area ratio of the differential cylinder (for example, two to one) from the piston rod side space, while twice the amount is displaced from the cylinder space at a pressure medium supply to Kolbenstangen suem space.
  • the pump logic be greater than the tank logic in the unit associated with the piston rod-side pressure chamber and the tank logic larger than the pump logic in the unit assigned to the cylinder chamber.
  • the basic block of the tank channel has a larger effective cross section than the pump channel.
  • this is achieved by two interconnected tank channels are connected in parallel with approximately the same cross-section.
  • these two tank channels extend in a parallel plane to a side surface and the pump channel is arranged in a central plane to the plane defined by the tank channels level.
  • the basic block is approximately cuboid, with the tank and pump and possibly control ports preferably open at the front.
  • the axis of a logic associated with the pump port is formed in parallel and the axis of logic associated with the tank port is perpendicular to the axis of the load port.
  • the axis of the load port may also be perpendicular to the axis of the pump logic and parallel to the axis of the tank logic.
  • the consumer connections can be formed on the large block of the block disc facing away from the base block or on the side surfaces, wherein the arrangement of the consumer connection on the smaller side surface of a block-shaped block disc is preferred.
  • the production of the basic block can be further simplified if the tank and pump channels through at a casting inserted tubes are formed. Unused channels could then be shut off, for example by screw plugs.
  • connection channels preferably run at right angles to the parallel tank or pressure channels.
  • FIG. 1 shows in a greatly simplified form a circuit in which a hydraulic cylinder 1 can be connected via a control block 2 to a pressure connection P or a tank connection T.

  • the associated pressure chamber 10 and 12 with a pump channel 22 and each tank logic 18, 20 of the associated pressure chamber 12th or 10 are connected to a tank channel 24.
  • These two channels 22, 24 extend in the basic block 4 and are connected to the logic 14, 18; 16, 20 via connecting channels 26, 28, 30, 32 connected.
  • a conventional 4/3-way valve for controlling a differential cylinder with additional functions (check valve function, pressure and flow control) can be provided by the selection of suitable logic valves and pilot controls.
  • Each of the indicated tank / pump logic has a 2-way cartridge valve and one or more pilot valves (not shown), via the latter in the closing direction of a closing cone of the cartridge valve effective pressure chamber can be acted upon with pressure medium or connected to a tank.
  • the logic valves are designed with different control covers to connect the required pilot valves.
  • the base block 4 is formed as a rectangular ingot, at its visible in Fig. 2 end face 34 two interconnected tank channels 24a, 24b and the pump channel 22 open so that the front side via corresponding connection images a tank connection T or a pressure port P is formed.

  • each side of the base block 4 may be occupied by block disks or valves.
  • the length L of the control block depends on the number of block disks to be fastened, a basic block 4 of this length L being cut off as required from a prefabricated cast block in which at least the channels 22, 24 are already formed.

  • connection channels 26, 28; 30, 32 formed as perpendicular to the respective side surfaces 40, 42 extending bores, so that they can be incorporated in a simple manner subsequently in the prefabricated basic block 4. Due to the triangular offset of the channels 24a, 24b, 22, the connection channels can be formed extremely easily without the risk of overlapping.
