Claims
- 1. An extrusion die comprising:
a mandrel; a member positioned about said mandrel; an extrusion orifice between said mandrel and said member; a first device which positions said member and said mandrel relative to each other, wherein said device moves the member and the mandrel relative to each other and fixes the positions of said member and said mandrel.
- 2. An extrusion die as claimed in claim 1, wherein said first device modifies a geometry of said extrusion orifice.
- 3. An extrusion die as claimed in claim 1, wherein said first device shifts said member in a direction transverse to a longitudinal axis of said member.
- 4. An extrusion die as claimed in claim 1, further comprising a mounting plate, wherein said mandrel is mounted to said mounting plate, and wherein said first device engages said mounting plate.
- 5. An extrusion die as claimed in claim 1, wherein said positioning device comprises an outer die structure which is comprised of said member and a support portion, wherein said support portion is attachable to the mounting plate.
- 6. An extrusion die as claimed in claim 1, wherein said first device comprises a lug and a bolt wherein said lug is attached to said mounting plate, wherein said bolt is supported by said lug, and wherein said bolt engages an outer die structure of said first device.
- 7. An extrusion die as claimed in claim 1, wherein said first device comprises a slip hole and a locking apparatus, said locking apparatus comprises a fastener which extends through the slip hole.
- 8. An extrusion die as claimed in claim 1, wherein said first device comprises a plurality of shifting apparatuses for moving said member relative to said mandrel.
- 9. An extrusion die as claimed in claim 1, wherein said first device comprises a plurality of locking apparatuses for fixing the position of said member relative to said mandrel.
