Claims20
A component of hydraulics configured for controlling a pressure medium connection or pressure medium flow, the component comprising:
- a first portion which is additively manufactured at least in part and on which at least one control geometry is formed, the at least one control geometry configured for controlling the pressure medium connection or pressure medium flow;
- and
- a second portion which is joined to the first portion by friction welding.
An arrangement comprising:
- a loose first portion of a component of hydraulics,
- wherein the loose first portion is configured to be joined by friction welding to a loose second portion to form a component,
- wherein the first portion is at least partially additively manufactured and has at least one control geometry configured for controlling a pressure medium connection or pressure medium flow, and
- wherein the first portion includes a clamping region configured to absorb a clamping force and/or a clamping moment during the joining by friction welding.
A method for joining a first portion and a second portion of a component of hydraulics to form said component, wherein the first portion is at least partially additively manufactured and includes (i) at least one control geometry configured for controlling a pressure medium connection or pressure medium flow and the (ii) a clamping region configured for attachment of a clamping device, the method comprising:
- clamping the first portion at the clamping region;
- clamping the second portions;
- positioning the first and second portions relative to and/or against one another;
- and
- joining the first portion to the second portion by friction welding to form a material-bonded connection between the first and second portions.
