Abstract
The disclosure relates to a hydraulic control block for controlling a pressure medium supply of a hydraulic cylinder of a hydraulic spindle. The hydraulic control block includes a generic hydraulic switching structure electively configurable in each of a plurality of specific hydraulic switching structures, each of the plurality of specific hydraulic switching structures having a respective hydraulic cylinder with a number of piston areas which differs from a number of piston areas in the respective hydraulic cylinders of each of the other of the plurality of specific hydraulic switching structures.
Claims10
A hydraulic control block for controlling a pressure medium supply of a hydraulic cylinder of a hydraulic spindle, comprising:
- a generic hydraulic switching structure electively configurable in each of a plurality of specific hydraulic switching structures, each of the plurality of specific hydraulic switching structures having a respective hydraulic cylinder with a number of piston areas which differs from a number of piston areas in the respective hydraulic cylinders of each of the other of the plurality of specific hydraulic switching structures;
- a first supply interface configured to be electively fluidically connected to at least one of a high-pressure side of a hydraulic machine of the hydraulic spindle and a low-pressure side of the hydraulic machine;
- a second supply interface configured to be electively fluidically connected to at least one of the high-pressure side and the low-pressure side of the hydraulic machine;
- a first working flow path configured to be electively fluidically connected to the first supply interface;
- a second working flow path configured to be electively fluidically connected to the second supply interface;
- a third working flow path configured to be electively fluidically connected to the first supply interface in parallel with the first working flow path;
- at least one first working port branched off from the first working flow path;
- at least one second working port branched off from the second working flow path;
- at least one third working port branched off from the third working flow path;
- and
- a valve in the third working flow path configured to electively close and open said third working flow path.
