High pressure press with tensioning assembly and related methods
View Patent ↗A high pressure press assembly along with related methods and components for the press assembly are provided. In one embodiment, a press assembly includes a first press base having one or more tie bar receiving holes extending therethrough. A second press base may also include one or more tie bar receiving holes extending therethrough. A tie bar extends between the first press base and the second press base. A tensioning assembly is operatively coupled to the tie bar to place the tie bar in tension.
1. A high pressure press assembly, comprising:
a first press base having a tie bar receiving hole extending therethrough;
a second press base having a tie bar receiving hole extending therethrough;
a tie bar having a first end and a second end opposite the first end, wherein the tie bar extends between the first press base and the second press base; and
a tensioning assembly comprising a multi-jack bolts tensioner coupled to the first end of the tie bar, wherein the tensioning assembly is sized and configured to place the tie bar within 1,000 pounds per square inch of a selected amount of tension.
2. The high pressure press assembly of claim 1 , wherein the multi-jack bolt tensioner includes a nut body and one or more jack bolts housed in the nut body.
3. The high pressure press assembly of claim 2 , further comprising a washer disposed between the nut body and the second press base.
4. The high pressure press assembly of claim 3 , wherein the one or more jack bolts are positioned and configured to press against the washer.
5. The high pressure press assembly of claim 2 , wherein the first end of the tie bar comprises threads and the nut body comprises threads compatible with the threads of the first end of the tie bar.
6. The high pressure press assembly of claim 2 , wherein the nut body and the first end of the tie bar are configured to effect a breech lock therebetween.
7. The high pressure press assembly of claim 6 , wherein the breech lock is effected through rotational engagement of one or more thread segments on the nut body with one or more thread segments on the first end of the tie bar.
8. The high pressure press assembly of claim 7 , wherein the one or more thread segments of the nut body and the one or more thread segments of the first end of the tie bar are sized and configured to engage or disengage by relative rotation of the nut body and the tie bar of a magnitude less than 360°.
9. The high pressure press assembly of claim 1 , wherein the second press base comprises a tie bar cavity and wherein the first end of the tie bar protrudes into the tie bar cavity.
