Abstract
Abstract An improved insulated forming press for forming structures at elevated temperatures and pressures is disclosed. Vertical rams move vertical heated platens, vertical ram insulation blocks, and vertically oriented forming dies, to close about a workpiece. The workpiece, insulation blocks, platens, and dies are supported by two sets of interlocking support members. One ram is activated by a plurality of mechanical jack screws, and the other is activated by a plurality of hydraulic cylinders that utilize a nonflammable mixture of water glycol. After forming is completed, the tooling can be automatically separated by retracting the rams and the workpiece is removed vertically.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
131 words
An apparatus for sealing tooling about a workpiece, which comprises: two substantially rigid and vertical rams which oppose each other and are substantially parallel to each other, said rams being in a horizontally spaced relationship; support means under said tooling and said workpiece for supporting said tooling and said workpiece between said vertical rams; and pressure means for moving said rams to vary said spaced relationship and clamp said tooling about said workpiece such that said tooling is sealed about said workpiece, said pressure means including a mechanical means for moving one ram and a fluid pressure means for moving the other ram, said one ram movable by said mechanical means having a substantially greater range of horizontal movement than said other ram which is movable by said fluid pressure means.
Claim 2
Independent Claim
131 words
An apparatus for sealing tooling about a workpiece, which comprises: two substantially rigid and vertical rams which oppose each other and are substantially parallel to each other, said rams being in a horizontally spaced relationship; support means under said tooling and said workpiece for supporting said tooling and said workpiece between said vertical rams; and pressure means for moving said rams to vary said spaced relationship and clamp said tooling about said workpiece such that said tooling is sealed about said workpiece, said pressure means including a mechanical means for moving one ram and a fluid pressure means for moving the other ram, said one ram movable by said mechanical means having a substantially greater range of horizontal movement than said other ram which is movable by said fluid pressure means.
Claim 3
Dependent Claim
17 words
The apparatus of claim 1, further comprising a means positioned between said rams for heating said workpiece.
Claim 4
Dependent Claim
15 words
The apparatus of claim 1, wherein said pressure means employs a nonflammable water glycol solution.
Claim 5
Dependent Claim
42 words
The apparatus of claim 1, wherein said fluid pressure means selectively moves said other ram into a transverse orientation relative to said one ram so as to improve alignment with said tooling, whereby pressure can be applied more uniformly to said tooling.
Claim 6
Dependent Claim
21 words
The apparatus of claim 4, wherein said pressure means comprises a plurality of hydraulic cylinders attached to said other vertical ram.
Claim 7
Dependent Claim
20 words
The apparatus of claim 5, wherein pressure can be applied by said hydraulic cylinders differentially to effect said transverse orientation.
Claim 8
Dependent Claim
20 words
The apparatus of claim 6, wherein only a portion of said hydraulic cylinders are used to effect said transverse orientation.
Claim 9
Dependent Claim
13 words
The apparatus of claim 1, wherein said tooling rests on said support means.
Claim 10
Dependent Claim
27 words
The apparatus of claim 8, wherein said support means comprises two intermeshing support members, each of said support members comprising a plurality of substantially parallel spaced legs.
Claim 11
Dependent Claim
21 words
The apparatus of claim 8, wherein said support means is horizontally disposed and said workpiece and said tooling are positioned vertically.
Claim 12
Dependent Claim
21 words
The apparatus of claim 9, wherein said support means is horizontally disposed and said workpiece and said tooling are positioned vertically.
Claim 13
Dependent Claim
35 words
The apparatus of claim 11, wherein said tooling comprises two tooling members, one of said tooling members resting on one of said support members, and the other tooling member resting on the other support member.
Claim 14
Dependent Claim
103 words
The apparatus of claim 8, wherein said support means comprises two support members, each of said support members respectively attached to one of said vertical rams, and wherein said tooling comprises two tooling members, one of said tooling members resting on one of said support members, the other tooling member resting on the other support member, said workpiece positioned between said tooling members, said workpiece and said tooling members positioned vertically, whereby said workpiece can be vertically inserted and removed from between said tooling members when said tooling members are separated from each other by virtue of the horizontal positioning of said rams.
Claim 15
Dependent Claim
60 words
The apparatus of claim 12, wherein each of said support members is respectively attached to one of said vertical rams, said workpiece is positioned between said tooling members, whereby said workpiece can be vertically inserted and removed from between said tooling members when said tooling members are separated from each other by virtue of the horizontal positioning of said rams.
Claim 16
Dependent Claim
28 words
The apparatus of claim 8, wherein said support means comprises two intermeshing support members, and one of said support members is elevated relative to the other support member.
Claim 17
Dependent Claim
19 words
The apparatus of claim 14, wherein one of said support members is elevated relative to the other support member.
Claim 18
Independent Claim
190 words
An apparatus for sealing tooling about a workpiece, which comprises: two substantially rigid and vertical rams which oppose each other and are substantially parallel to each other, said rams being in horizontally spaced relationship; support means for supporting said tooling and said workpiece between said rams, said support means being under said tooling and workpiece and between said rams, said tooling resting on said support means, said support means comprising two support members, each of said support members respectively attached to one of said vertical rams, said tooling comprising two tooling members, one of said tooling members resting on one of said support members, the other tooling member resting on the other support member, said workpiece being positioned between said tooling members, said workpiece and said tooling members positioned vertically; and pressure means for moving said rams to vary said spaced relationship and clamp said tooling about said workpiece such that said tooling is sealed about said workpiece, whereby said workpiece can be vertically inserted and removed from between said tooling members when said tooling members are separated from each other by virtue of the horizontal positioning of said rams.
Claim 19
Independent Claim
190 words
An apparatus for sealing tooling about a workpiece, which comprises: two substantially rigid and vertical rams which oppose each other and are substantially parallel to each other, said rams being in horizontally spaced relationship; support means for supporting said tooling and said workpiece between said rams, said support means being under said tooling and workpiece and between said rams, said tooling resting on said support means, said support means comprising two support members, each of said support members respectively attached to one of said vertical rams, said tooling comprising two tooling members, one of said tooling members resting on one of said support members, the other tooling member resting on the other support member, said workpiece being positioned between said tooling members, said workpiece and said tooling members positioned vertically; and pressure means for moving said rams to vary said spaced relationship and clamp said tooling about said workpiece such that said tooling is sealed about said workpiece, whereby said workpiece can be vertically inserted and removed from between said tooling members when said tooling members are separated from each other by virtue of the horizontal positioning of said rams.
