Definitions

  • the present invention relates to a method for producing a hollow body for high internal or external pressure according to the preamble of claim 1.
  • Known hollow bodies for high internal pressure are known in the form of steel gas cylinders for technical gases such as oxygen, hydrogen, nitrogen, helium or the like, for example for welding purposes. These hollow bodies are designed for pressures up to over 200 bar. High-pressure bottles of this type must be checked for strength at certain intervals, since the weld seams in particular represent a particular source of danger. High pressure tanks made of steel or aluminum are also used in the automotive industry, for example for inflating air bags or for storing natural gas (CNG) or hydrogen (H 2 ) for alternative drives. These high pressure tanks are relatively heavy and expensive to manufacture for the required operating pressures of up to about 600 bar and the specified burst pressure of up to about 700 bar.
  • CNG natural gas
  • H 2 hydrogen
  • the object of the present invention is to be able to produce a hollow body for very high internal or external pressures economically, economically in terms of production technology, inexpensively and with low weight.
  • the gas-tight layer can be made relatively thin and also made of plastic and can be produced very inexpensively with a low weight.
  • FIG. 1 is a side view of a hollow body according to the invention, partly in section,
  • Fig. 1 denotes a hollow body with an opening 2.
  • the opening 2 is sealed gas-tight with a pressure-resistant membrane 3.
  • the hollow body 1 consists of an inner gastight preform 4 which has undergone the processes listed below and an outer layer 5 which surrounds it without inclusion and which essentially determines the compressive strength of the hollow body 1.
  • the hollow body 1 is produced by the following process steps according to the invention:
  • a preform 6, a so-called preform, is produced for an inner container 4 to be produced therefrom from metal or in particular from a gas-tight plastic, that is to say highly resistant to gas permeation.
  • a gas-tight plastic that is to say highly resistant to gas permeation.
  • the preform 6 has a size of only about 1/3 or 1/4 the size of the inner container 4 to be produced or even less.
  • the preform 6 has a handling part 7, for example for holding and manipulating the inner container 4 and a section 8 to be expanded, which later forms the actual inner container 4.
  • Method step 3 inserted into an at least two-part first mold and inflated or expanded by applying a high internal pressure to the shape of the inner container 4.
  • Molecular orientation occurs in the plastic, which significantly increases the strength of the plastic.
  • the inner container 4 obtained in this way can then be provided with a reinforcement 9 in an optional method step 4), depending on the required load capacity, which is indicated in FIG. 1 by the cross hatching.
  • This reinforcement 9 can be made of metal, for example made of high-strength steel, chrome steel, chrome-nickel steel, copper, brass, bronze or of another high-strength metal or a metal alloy, for example in the manner of cans as are commercially available for lemonades or beer. or consist of a high-strength plastic.
  • the reinforcement 9 is pushed in the form of wire, fabric, braid, as a corrugated tube, fabric hose, in a spiral shape or the like over the inner container 4 or wound onto the inner container 4.
  • a high internal pressure is generated in the inner container 4, which completely or almost completely prevents the same from being deformed.
  • a process step 5 the inner container 4 or the reinforced inner container 4 is inserted into a further at least two-part form which is larger than the inner container 4 or the reinforced inner container 4 and encapsulated therein with a heavy-duty plastic 10.
  • the optionally reinforced inner container 4 can also be immersed in a polymerizable and hardening plastic made in particular of epoxy or polyester resin. It can also be wet-wrapped with a reinforcing material that is soaked or surrounded with a polymerizable and hardening plastic compound. In both of these cases, the polymerization and curing take place while the inner container 4 is rotating in the horizontal position thereof.
  • the encapsulation or wet wrapping takes place at such high internal pressure in the inner container 4 that the external pressure does not deform it, or at most only slightly deforms it, in particular it is not pressed in.
  • a plastic is preferably used, the degree of shrinkage of which is equal to or greater than that of the preform 6. Threads, fabrics, braids, felt or the like made of glass and / or carbon and / or minerals and / or plastic, in particular aramid, are suitable.
  • the overmolded, dipped or wet-wrapped and possibly also reinforced inner container 4 is introduced into a further, slightly larger, at least two-part form in the still warm-elastic state or after heating to a corresponding temperature and in the inner container 4 creates a high internal pressure.
  • the structure expands slightly, a firm connection of the molded plastic or applied by dipping or wet wrapping with the inner container 4 being achieved.
  • the hollow body 1 thus formed is removed in process step 7) cooled down.
  • the cooling can be controlled according to certain criteria according to a certain curve in order to achieve the highest possible strength of the hollow body 1 and not to deteriorate the strength of the inner container 4.
  • test pressure is approximately 120% to 180% of the operating pressure, which can reach up to 600 bar.
  • the pressure is suitably chosen so that it is about 30% to 80% less than the bursting pressure, which can reach up to 700 bar.
  • the burst pressure can e.g. 15% to 200% greater than the operating pressure.
  • method step 5 is replaced by the following method steps:
  • the expanded inner container 4 is surrounded or wrapped with a reinforcement, which is impregnated with an impregnating agent made of a hardenable plastic or - similar to the so-called known prepregs. Threads, fabrics, braids, felt or the like made of glass, carbon, mineral and / or plastic fibers are also used for reinforcement. If plastic is used, aramid is preferably used. When reinforcing, especially when winding, such a high internal pressure is generated that a deformation of the inner container 4 is prevented or almost prevented.
  • the impregnating agent is polymerized and hardened or hardened by suitable measures, for example by heating.
  • the degree of shrinkage during polymerisation and hardening or hardening and / or during cooling is preferably equal to or greater than that of the material or in the case of a multi-layer construction of the materials of the inner container 4. It can namely be advantageous to produce the inner container 4 from several layers of material, the individual layers are firmly connected.
  • Polyethylene (PE) and / or polyethylene terephthalate (PETP) are preferably suitable as materials for this.
  • Epoxy and / or polyester resin is preferably used as the material for the overmolded outer layer 5 or for the impregnating agent.
  • the reinforced inner container 4 is impregnated with a hardenable plastic or the inner container 4 or the reinforced inner container 4 is immersed in a hardenable plastic and then polymerized and cured with constant rotation of the inner container 4 in its horizontal position.
  • Process steps 1) to 9) can be carried out in individual steps, or - as indicated in FIG. 3 - in a cyclic process or - as shown schematically in FIG. 4 - in a linear process sequence.

Abstract

Pour produire un corps creux (1) comportant au moins une ouverture (3) pour pression intérieure ou extérieure élevée, une ébauche (6) (ou préforme) en métal ou notamment en plastique est élargie à l'aide d'une pression intérieure élevée pour former un récipient intérieur (4) et est éventuellement à l'extérieur, armée, recouverte par extrusion, trempée ou enrobée sous pression intérieure élevée. A cet effet, la pression intérieure est choisie de manière que pendant la formation de l'armature, le recouvrement par extrusion, la trempe ou l'enrobage, il n'intervienne qu'une légère déformation du récipient intérieur (4).
