Zusammenfassung: | The press comprises a container defining a cylindrical free volume in which is placed a billet and a punch. The container is clamped onto a tool arrangement which contains a die with an opening corresp. to the cross-section of the profile. The tool arrangement also includes a rear part called a 'porthole' which has channels for feeding the reinforcement and between the porthole and the die a feeder head with guide nozzles extending the feed channels. The nozzles open out opposite the opening of the die, the feed channels being curved so that they emerge between the container and the porthole. The press. is used for producing Al, Cu, or Zn profiles reinforced with high strength metals such as steel, W, Mo or an alloy based on these metals. Profiles with part or discontinuous reinforcement can be obtd. |
