Radial compression element for a HTHP cartridge
View Patent ↗A cartridge assembly for connection to a frame of a high temperature, high pressure press, having an anvil at a front end of a cylindrical body of the cartridge and a hydraulic chamber within the body adapted to apply axial pressure to the anvil. A radial compression element is disposed around an outer diameter of the body and is adapted to limit radial expansion of the body proximate the hydraulic chamber.
1. A cartridge assembly for connection to a frame of a high temperature, high pressure press, comprising:
an anvil at a front end of a cylindrical body of the cartridge and a hydraulic chamber within the body adapted to apply axial pressure to the anvil; and
a radial compression element disposed around an outer diameter of the body and adapted to limit radial expansion of the body proximate the hydraulic chamber.
2. The assembly of claim 1 , wherein the radial compression element is a solid annular ring.
3. The assembly of claim 1 , wherein the radial compression element is a wrap.
4. The assembly of claim 3 , wherein the wrap is wound at an angle with respect to a central axis of the assembly.
5. The assembly of claim 1 , wherein the radial compression element comprises a varying thickness in an axial direction.
6. The assembly of claim 1 , wherein the radial compression element comprises an axial length from 4 to 16 inches.
7. The assembly of claim 1 , wherein the radial compression element comprises a thickness from 1 to 5 inches.
8. The assembly of claim 1 , wherein the radial compression element comprises an interference fit around the body of 0.001 to 0.150 inches.
9. The assembly of claim 1 , wherein the radial compression element is made of a material with a hardness from 200 to 450 HB.
10. The assembly of claim 9 , wherein the material is steel.
11. The assembly of claim 9 , wherein the material is softer than the cylindrical body.
12. The assembly of claim 1 , wherein the radial compression element comprises an outer surface with at least one groove.
13. The assembly of claim 1 , wherein the radial compression element comprises a chamfered outer surface.
14. The assembly of claim 1 , wherein the radial compression element comprises a protrusion adapted for alignment of the assembly within the frame.
15. The assembly of claim 1 , wherein the assembly comprises a grit between the body and the radial compression element.
16. The assembly of claim 1 , wherein the assembly comprises a plurality of radial compression elements disposed around the outer diameter of the body.
17. A method for use in high temperature, high pressure processing, comprising:
providing a cartridge adapted for connection to a frame of a high temperature, high pressure press with an anvil at a front end of the cylindrical body of the cartridge and a hydraulic chamber within the body adapted to apply axial pressure to the anvil; and
compressing an outer diameter of the body proximate the hydraulic chamber by fitting a radial compression element around the outer diameter.
18. The method of claim 17 , wherein the step of compressing the outer diameter includes thermally expanding the radial compression element.
19. The method of claim 17 , wherein the step of compressing the outer diameter includes thermally shrinking the cylindrical body.
20. The method of claim 17 , wherein the step of compressing the outer diameter includes wrapping a material around the cylindrical body.
