Reinforced press base, strengthening ring, and method of reinforcing a press base
View Patent ↗Embodiments of the present invention include a press base assembly, a strengthening ring for use with press bases and related methods. In one embodiment, a press base assembly includes a press base having a body that includes a piston cavity at one end. The body, at a second end opposite that of the piston cavity, may exhibit a desired geometry. A strengthening ring may be shaped, sized and configured to substantially mate with the geometry of the second end of the body and be placed thereover. For example, the geometry of the second end may be substantially circular exhibiting a particular diameter and circumference. The strengthening ring may have substantially circular internal surface sized and configured such that the strengthening ring is positioned on the second end of the body in a manner that results in an interference fit between the two components.
1. A press base assembly comprising:
a press base comprising:
a first end having a first outer diameter and first outer circumference;
a second end opposite the first end;
a piston cavity;
at least one tie rod receiving hole located between the first end and second end; and
a strengthening ring positioned around, and configured to maintain contact with, the first outer circumference of the press base.
2. The press base assembly of claim 1 , wherein the strengthening ring is pre-stressed.
3. The press base assembly of claim 1 , wherein the strengthening ring further comprises:
a first annular surface;
a second annular surface opposite the first annular surface;
an inner diameter wall substantially perpendicular to each of the first annular surface and the second annular surface; and
an outer diameter wall opposite the inner diameter wall and substantially perpendicular to each of the first annular surface and the second annular surface.
4. The press base assembly of claim 1 , wherein the strengthening ring is secured to the press base.
5. The press base assembly of claim 4 , wherein the strengthening ring is secured to the press base by an interference fit between the strengthening ring and the press base.
6. A press base assembly comprising:
a press base comprising:
a first end having a first outer diameter and first outer circumference;
a second end opposite the first end;
a strengthening ring positioned around the first outer circumference of the press base; and
a support bar coupled with a first portion of the strengthening ring and a second portion of the strengthening ring.
7. The press base assembly of claim 1 , wherein the strengthening ring comprises steel.
8. The press base assembly of claim 1 , wherein the strengthening ring is formed as a single, continuous structure.
9. The press base assembly of claim 6 , wherein the strengthening ring is pre-stressed.
10. The press base assembly of claim 6 , wherein the strengthening ring further comprises:
a first annular surface;
a second annular surface opposite the first annular surface;
an inner diameter wall substantially perpendicular to each of the first annular surface and the second annular surface; and
an outer diameter wall opposite the inner diameter wall and substantially perpendicular to each of the first annular surface and the second annular surface.
11. The press base assembly of claim 6 , wherein the strengthening ring is secured to the press base.
12. The press base assembly of claim 11 , wherein the strengthening ring is secured to the press base by an interference fit between the strengthening ring and the press base.
13. The press base assembly of claim 6 , wherein the strengthening ring comprises steel.
