Definitions

  • the invention relates to semi-finished products with a metal foam core and methods for their production.
  • US 30 87 807 A and DE 40 18 360 C1 for producing a metal foam body.
  • US 30 87 807 A shows that a hollow body can be filled with a metal foam by producing the metal foam inside the hollow body.
  • DE 44 43 840 C2 shows a pra l I protection for a motor vehicle trim part.
  • a cushion made of light metal foam is completely enclosed in a coat.
  • the publication does not indicate whether and how the light metal foam is attached to the inside of the jacket.
  • rotating rollers are e.g. B. in the form of Papi he Le twa Izen or z. B. hollow cylinder known as molded or rubber tuchzy li nder.
  • paper guide rollers are driven by the web to be guided by them itself. This can lead to an undesired influencing of the print carrier web, ie for example a paper web or film web, since, as said, the energy for acceleration or braking must be applied to the rollers themselves via the print carrier web.
  • the paper web widths are getting larger (e.g. 3.80 m) and, on the other hand, the paper web widths are getting larger (e.g. 3.80 m) and, on the other hand, the paper web widths are getting larger (e.g. 3.80 m) and, on the other hand, the paper web widths are getting larger (e.g. 3.80 m) and, on the other hand, the paper web widths are getting larger (e.g. 3.80 m) and, on the other hand,
  • Print carrier web speeds are also increasing and are now 18 m / sec. achieved.
  • the invention has for its object to provide semi-finished products for rollers and cylinders intended for rotating operation with a metal foam core and methods for their production.
  • rollers, cylinders and the like can be created with a metal foam core for rotary operation at high speeds, which can have a jacket that is dependent on the high temperatures (e.g. 500 ° C), which are necessary for the production of metal foam, is not burdened.
  • Metal pairs, e.g. B. rolls of steel can be filled with an aluminum foam, without it during rotation of the rolls / cylinders during acceleration and braking to a relative movement between the inner surface of the roll and
  • the Papi he Lei twa Izen can be dispensed with.
  • the tubular body - called coat below - can be made of any material, for. B. of metal (steel, aluminum, brass, etc.), plastic, for. B. consist of polyamide, ceramic or paper. Its interior cross-section can have any geometric shape: circular, square, single, multiple, longitudinally grooved, as a counterpart to a spline shaft (single spline, multiple spline), serrated shaft, K-Prof i Iwe l le etc.
  • the interior cross-section of the jacket can therefore be any. However, it must be designed so that one or more metal foam core (s) can be introduced from one of the openings on the end faces of the rollers / cylinders or, in the case of multi-part metal foam cores, from both end faces.
  • the metal foam core is made spatially separate from the jacket and later brought into the interior of the jacket.
  • the metal foam core can be manufactured in various ways known per se, e.g. B. by the methods as described in DE 40 18 360 C1. However, the foaming in the method according to the invention takes place outside the jacket to be filled. According to the invention, the metal foam core is introduced into the interior of the jacket in a quasi finished state and is fastened to the inside wall of all or only parts of the inside surface of the jacket.
  • the connection between the outer surface of the metal foam core and the inner surface of the jacket must be designed in such a way that it at least partially enables a force transmission between the jacket inside and the metal foam core via its outer surface.
  • This connection can be designed as a detachable connection or non-detachable connection.
  • the detachable connections can be positive connections, e.g. B. are profile connections, spring connections, but screw connections are also suitable.
  • the inner surfaces of the shell of the semi-finished product and the surface of the metal foam core must be adapted to one another, for. B. internal thread in the jacket, external thread on the metal foam core, metal foam core surface provided with a longitudinal wedge or as a "spline shaft” and the inner surface of the jacket with a corresponding groove (s).
  • Non-positive connections in the form of a cone connection would also be possible (outer cone for the metal foam core, inner cone for the jacket).
  • These releasable connections can also be made non-positively by additionally using a shrink bond.
  • the sheath is heated and the metal foam core is introduced into the inside of the sheath.
  • the metal foam core can also be cooled. After the temperature equalization between them, a very stable, form-fitting, force-fitting connection is created.
  • connection between the jacket and the metal foam core can also be seen as a material connection, e.g. B. Adhesive connection or as a visually lüss i ge connection, z. B. shrink connection or as a combined sto f- / kra t seh lüss i ge connection.

  • anaerobic adhesives are particularly suitable, which allow a connection of different metals in a simple manner.
