Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical manufacturing, and in particular relates to a disassembly tool for an ultra-high pressure container with a shear ring structure, which is used when assembling and disassembling a four-ring of an ultra-high pressure container with a shear ring structure. Background Art

[0002] Ultra-high pressure vessels have become very important and indispensable tools in chemical industry, petrochemical industry, artificial crystal, synthetic diamond and other hydrostatic processing, ultra-high hydrostatic pressing, powder metallurgy, metal forming, as well as geophysical and geomechanical research.

[0003] Ultrahigh-pressure vessels operate under extremely high pressures and stress levels. Therefore, ensuring long-term, stable, and safe operation is a crucial factor in their design and structural selection. Ultrahigh-pressure vessels are primarily cylindrical vessels, and their stress distribution is characterized by the following characteristics: ① Of the three principal stresses, the circumferential stress is the greatest. ② The circumferential stress distribution is highest at the inner wall and is uneven along the wall thickness, becoming more severe as the diameter ratio (k) increases. Furthermore, when the operating pressure exceeds 0.05, the inner wall will inevitably yield. Based on these stress characteristics, when considering how to reduce stress levels in ultrahigh-pressure cylindrical vessels under operating conditions, it is not enough to simply increase thickness or improve material strength. Instead, structural changes must be considered to alter the stress distribution. A shear ring is a circular ring composed of four or eight components. This structure provides relatively dispersed stress and facilitates assembly and disassembly, making it suitable for vessels requiring quick opening. Utility Model Content

[0006] The disassembly frame is connected to the central cylindrical boss of the support frame through a matching hole opened in its center. The disassembly frame can be rotated arbitrarily along the circumferential direction. When in use, when there are many shear ring pieces, the shear rings in different directions can be disassembled by rotating the disassembly frame.
