Definitions

  • the invention relates to a pressure vessel according to the preamble of the main claim.
  • the upper part to be crimped has the same wall thickness everywhere, which has the disadvantage that when crimping the wall thickness thickens in the upper part and is even so massive that the other housing parts, in particular in the lower region of the Housing thickening result, which are completely undesirable. This stems from the fact that the upper part has become more solid than the lower part.
  • the pressure vessel according to the invention with the characterizing features of the main claim has the advantage that the upper housing part receives the same wall thickness everywhere by crimping and that there is no effect on the wall thickness in other container regions. This gives a particularly stable housing that is also simple and therefore economical to manufacture.
  • Figure 1 shows a pressure accumulator in longitudinal section
  • Figure 2 shows the housing after a certain process step.
  • the pressure accumulator essentially consists of a closed housing 10, in the interior of which a membrane 11 made of elastic material is arranged, which divides it into a liquid space 12 and a gas space 13.
  • the membrane 11 is pressed with its edge 15 against a housing shoulder 16 by a metallic expansion ring 14 and is held there.
  • a nozzle 18 At the lower part of the housing there is a nozzle 18 with a continuous liquid hole 19. On the opposite part of the housing there is a gas inlet opening 20 which is closed by a screw 21. At the connector 18, the pressure accumulator is connected to a hydraulic system.
  • the housing 10 is made by extrusion from a metallic board.
  • a first operation under certain circumstances and depending on the size of the housing, two or more operations may be required for this - a hollow cylindrical structure is produced by extrusion with an approximately hemispherical lower housing part with a nozzle 18 formed thereon.
  • This pre-formed housing part is shown in FIG. 2.
  • the upper part 10 'of the housing is conical in such a way that the wall thickness tapers significantly upwards.
  • This taper can be produced by turning, by the extrusion process itself or by an ironing process. The taper is much greater than is necessary, for example, to pull out a press ram.
  • the shoulder 16 can also be produced by extrusion or again by turning.
  • the membrane 11 is inserted into the housing and fastened with the expansion ring 14. Then the upper part 10 'of the housing, ie the conical part, which extends over approximately half or a third of the housing interior, is crimped, so that a closed, approximately spherical housing results, as shown in FIG. 1. In this crimping process, the done by a special tool, the previously tapered wall thickness is now the same everywhere.
  • the lower part 10 "of the housing is shaped so that the wall thickness increases approximately evenly from the equator to the nozzle.
  • the taper in the region 10 'of the upper container part can of course also be on the outside, while the inner part is cylindrical, or on the outside and inside.
