Abstract
A metallic material 27 is placed between an upper die 6 and a lower die 13. Inert gas is fed into the processing chamber 17 defined by a transparent quartz tube 16. The dies 6 and 13 are heated together with the metallic material 27 by infrared lamps 20. The dies 6 and 13 are closed to form the material 27.
Claims6
A method of forming a metallic material comprising:
- placing a metallic material between dies;
- covering the metallic material and the dies with a transparent enclosure to define a sealed space accommodating the metallic material and the dies;
- heating the metallic material together with the dies with an infrared lamp arranged outside the transparent enclosure;
- and
- forming the metallic material by using the dies.
2 more elements
A forming apparatus comprising:
- first and second die supports, each adapted to retain a die for forming a metallic material;
- a drive arranged to cause relative movement between the die supports to form the metallic material;
- an infrared lamp adapted to heat the dies together with the metallic material;
- and
- a transparent tube adapted to define therein a sealed space that accommodates the die supports with the infrared lamp being located outside the transparent tube, whereby the dies retained by the die supports and the metallic material located between the dies are collectively heated by infrared light emitted by the infrared lamp and transmitted through the transparent tube.
