Abstract

A die assembly for forming finished parts from blanks includes an upper die section and a lower die section. The upper die section includes an upper segmented die having a plurality of upper die segments releasably coupled to each other. The lower die section includes a lower segmented die having a plurality of lower die segments releasably coupled to each other. The die assembly is usable with a movable gantry press configured to move to a location of the die assembly and operate the die assembly.

First claim

The invention claimed is:

1. A die assembly for forming finished parts from blanks, the die assembly comprising:
an upper die section comprising an upper segmented die comprising a plurality of upper die segments releasably coupled to each other; and
a lower die section comprising a lower segmented die comprising a plurality of lower die segments releasably coupled to each other,
wherein the plurality of upper die segments is arranged in a linear array,
wherein each upper die segment comprises a coupling structure configured to releasably couple the upper die segment to an adjacent upper die segment,
wherein the coupling structure inhibits movement of the upper die segment with respect to the adjacent upper die segment in a longitudinal direction substantially parallel to the linear array, and
wherein the coupling structure allows movement of the upper die segment with respect to the adjacent upper die segment in a transverse direction substantially orthogonal relative to the longitudinal direction.

2. The die assembly of claim 1 , wherein, for each upper die segment, the coupling structure comprises:
a groove formed in the upper die segment, wherein the groove of the upper die segment corresponds to the groove in an adjacent upper die segment of the plurality of upper die segments, and

wherein the upper die section further comprises:
a retainer structure configured to simultaneously engage with the grooves of at least two adjacent upper die segments to inhibit movement of the at least two adjacent upper die segments with respect to each other in the longitudinal direction.

3. The die assembly of claim 2 , wherein the retainer structure comprises a ring-shaped element, and
wherein the grooves of the at least two adjacent upper die segments form a ring-shaped recess configured to releasably receive the ring-shaped element in the transverse direction to releasably couple the at least two adjacent upper die segments to each other.

4. The die assembly of claim 1 , wherein the coupling structure of a first upper die segment of the plurality of upper die segments comprises a protrusion,
wherein the coupling structure of a second upper die segment of the plurality of upper die segments comprises a groove that corresponds to the protrusion of the first upper die segment,
wherein the first upper die segment is configured to be lowered in the transverse direction into the linear array adjacent to the second upper die segment, wherein the groove of the second upper die segment releasably receives the protrusion of the first upper die segment to releasably couple the first upper die segments to the second upper die segment.

5. The die assembly of claim 1 , further comprising a plurality of heating elements coupled to at least one of the upper segmented die or the lower segmented die, wherein the plurality of heating elements are configured to heat the at least one of the upper segmented die or the lower segmented die to at least a predetermined temperature.

6. The die assembly of claim 5 , wherein the predetermined temperature is at least about 900 degrees F.

7. The die assembly of claim 5 , wherein the plurality of heating elements are coupled to the upper segmented die and the lower segmented die to heat the upper segmented die and the lower segmented die to at least the predetermined temperature.

8. The die assembly of claim 5 , wherein each upper die segment comprises a heating element recess,
wherein each lower die segment comprises a heating element recess; and
wherein a respective heating element of the plurality of heating elements is disposed in each of the heating element recesses in each of the upper die segments and the lower die segments.

9. The die assembly of claim 1 , further comprising:
a transfer plate releasably coupled to the upper segmented die, the transfer plate comprising an attachment point for an upper platen of a movable gantry press.

10. The die assembly of claim 9 , further comprising:
an upper insulation subassembly comprising:
an upper insulation material disposed around the upper segmented die; and
an upper cladding material disposed around an outer surface of the upper insulation material; and

a lower insulation subassembly comprising:
a lower insulation material disposed around the lower segmented die; and
a lower cladding material disposed around an outer surface of the lower insulation material.

11. The die assembly of claim 10 , further comprising:
a chill plate thermally coupled to at least one of the upper insulation material or the lower insulation material to facilitate cooling the die assembly.

12. The die assembly of claim 11 , wherein the chill plate further comprises:
exposed tubing for transporting a cooling fluid to facilitate cooling the die assembly.

13. The die assembly of claim 10 , further comprising a plurality of fastener assemblies, wherein each fastener assembly is configured to releasably attach a respective upper die segment to the transfer plate.

14. The die assembly of claim 13 , wherein each fastener assembly comprises a hanger pad and a hanger rod,
wherein each upper die segment comprises:
a hanger pad recess for receiving a respective hanger pad; and
a lower hole portion transverse to the hanger pad recess for receiving the hanger rod,

wherein the upper insulation subassembly comprises a plurality of upper hole portions corresponding to each of the lower hole portions of the upper die segments, and
wherein each hanger rod is configured to be inserted through a respective upper hole portion of the upper insulation subassembly and through a respective lower hole portion of a respective upper die segment to couple to the respective hanger pad of the fastener assembly in the hanger pad recess of the respective upper die segment, to releasably attach the transfer plate to the respective upper die segment.

15. A system for fabricating finished parts, the system comprising:
a plurality of die assemblies located at a plurality of respective locations, each die assembly being configured to fabricate a respective finished part, each die assembly comprising:
an upper die section comprising an upper segmented die comprising a plurality of upper die segments releasably coupled to each other; and
a lower die section comprising a lower segmented die comprising a plurality of lower die segments releasably coupled to each other;

a robot configured to move between the plurality of respective locations and selectively load blanks into the plurality of die assemblies; and
a movable gantry press configured to move between the plurality of respective locations and selectively operate the plurality of die assemblies to form finished parts from the blanks.

16. A die assembly for forming finished parts from blanks, the die assembly comprising:
an upper die section comprising an upper segmented die comprising a plurality of upper die segments releasably coupled to each other;
a lower die section comprising a lower segmented die comprising a plurality of lower die segments releasably coupled to each other;
a transfer plate releasably coupled to the upper segmented die, the transfer plate comprising an attachment point for an upper platen of a movable gantry press;
an upper insulation subassembly comprising:
an upper insulation material disposed around the upper segmented die; and
an upper cladding material disposed around an outer surface of the upper insulation material; and

a lower insulation subassembly comprising:
a lower insulation material disposed around the lower segmented die; and
a lower cla
