Definitions

  • the invention relates to a continuous extrusion process for a metal-containing bulk material for producing an extruded body, comprising the following steps:
  • Introducing the metal-containing bulk material into a press channel of a metal powder extrusion press which is delimited by a rotating extrusion wheel and press tool components, which comprise a gasket plate having an inlet region and a deflection region with a counter-holder and a feed plate,
  • metal-containing bulk material used in this application includes, inter alia, metal-containing powders, powder mixtures, granules, and chips, and may also be mixtures of metal powders with ceramic fibers or particles, that is, composites.
  • Components made of powder metallurgy materials can be used for example in the automotive industry, aerospace engineering and general engineering.
  • Continuous extrusion is a cost effective alternative to compact metal bulk materials, especially metal powders.
  • this process which is also referred to as the "conforming process”
  • Pressing processes have been developed to process granules or powders. It has been found that a stable process is difficult. An industrial use of such extrusion processes for metal-containing bulk materials therefore does not yet take place.
  • a conventional powder extruder suitable for the extrusion molding process comprises a rotary extrusion wheel with a circumferential groove and a stationary shoe comprising the feed plate arranged in the deflection region and the counter holder. At the opening having a feed plate, the die joins.
  • the crimping tool components forming the lead-in area and the deflection area extend over approximately one quarter of the circumference of the extrusion wheel.
  • the metal-containing bulk material in particular a metal-containing powder, is drawn into the inlet region and the deflection region by friction in the case of a rotating extrusion wheel. The metal-containing powder is thereby accumulated and compacted on the counter-holder.
  • the compacted powder is deflected at the anvil to the feed plate having the opening and to a die.
  • the individual cold powder particles weld into a fully compacted strand due to shear forces without the powder particles melting.
  • the friction and deformation forces that occur due to the rotation of the extrusion wheel generate the required temperatures and pressures for the continuous extrusion through the die.
  • WO 2008/003275 A1 describes a process for the production of molded parts from dispersion-hardened metal alloys.
  • Extrusion methods for metal powder mixtures are not yet implemented industrially, since usually no stable process control is possible.
  • powder adhesions occur in the area of the powder feed which clog the press channel and prevent a constant replenishment of the powder mixture. If the flow stress becomes too low during the extrusion process, complete compaction of the powder is not possible. It then builds on a sufficiently high pressure, which is required to completely weld particles of the metal-containing bulk material, in particular powder particles together.
  • the transported during the supply of the metal-containing bulk material flow per wheel revolution is reduced by the given bulk density.
  • the strand exit speeds therefore differ significantly from those with wire feed. This in turn causes longer residence times of the metal-containing, partially compacted bulk material in the pressure channel of the die, so that the risk of adhesions and thus pressing errors is higher on the sealing plates and on the die.
  • the invention is therefore based on the object to provide a continuous extrusion process for a metal-containing bulk material, which allows a stable process management.
  • an extruded body can be produced in a continuous process with high quality. It has been found that by cooling the inlet region of the press channel, powder adhering to the gasket plates can be avoided. This ensures a continuous powder feed and a uniform pressure build-up.
  • cooling of the pressing-tool components, in particular of the feeding plate causes a sufficiently high pressing pressure to be built up, which leads to break-up of oxide skins and welding of metal particles of the metal-containing bulk material.
  • a cooling in the area of the counter-holder would cause high compression pressures and increased chip formation, which may hinder or stop the entire process.

  • the pressing tool components form a pressing channel with the extrusion wheel.
