Abstract
A method for producing pressure vessels, including pressure accumulators, such as hydraulic accumulators and parts of the parts of the accumulator (24). The parts produced by a 3D printing method can include one or more or all of two housing parts and a separating element separating the interior chamber of the two hosing parts are at least partially produced by a 3D printing method.
Claims10
A method for producing pressure vessels, the method comprising the steps of:
- producing a first housing part with a first internal chamber by 3D printing;
- introducing a separating element in the first housing part after the producing of the first housing part;
- producing a second housing part with a second internal chamber on the first housing part after the introducing of the separating element such that the separating element separates the first and second internal chambers from one another preventing fluid communication therebetween and such that the first and second housing parts form an overall housing of a pressure vessel;
- attaching a closure part to an inner wall of the first housing part to retain the separating element at a location in the first housing part spaced from an end of the first housing part to which the second housing is coupled to the first housing part;
- and
- removing the closure part from the first housing part and the second housing part after coupling of the first and second housing parts, thereby forming an accumulator.
