As the HPHT Hydraulic Cubic Press scales up, continuous improvements in its design and manufacturing process have resulted in significant structural advantages, particularly in the design and manufacturing of the main frame structure.

1. Main Frame Structure Design and Optimization

 More Rational and Compact Structure: The design aims to reasonably reduce overall dimensions, which reduces equipment costs, makes the design more user-friendly, and ensures operability.

Optimized Hinge Beam: The Finite Element Method (using software like ANSYs) is employed to optimize the hinge beam design, leading to a more rational force distribution and structure.

Thin-Walled Work Cylinders: Thin-walled work cylinders are adopted to reduce the piston stroke while ensuring sufficient operating space.

2. Fundamental Improvement in Work Cylinder Load-Bearing Structure

In traditional presses, the work cylinder was the main load-bearing component, leading to frequent "cylinder cracking". Modern designs have shifted the load-bearing mechanism from the original flange support to bottom support or double support.

The core advantage of this modification is the transfer of the main load-bearing function from the work cylinder to the hinge beam. This change has successfully and completely solved the common problem of "cylinder cracking".

A. "Double Support Structure" (Example: Guilin Metallurgical Machinery General Factory):

1. Thin-Walled, Live-Bottom, Split-Type Work Cylinder: Reduces the work cylinder wall thickness from over 80mm to 30mm.

2. Facilitates Scaling Up: Significantly reduces the overall dimensions of the main machine, which is favorable for large-scale development.

3. Rational Force Distribution: The double-support structure allows the force to be rationally distributed between the bottom and the upper end face of the hinge beam.

4. Improved Piston Durability: A wear-resistant band is designed on the piston to prevent scratching the work cylinder.

B. "Bottom Support Structure" (Example: Designed by Lü Fengnong):

1. Improved Overall Machine Concentricity: Achieves a gap-free fit between the work cylinder and the hinge beam, significantly improving the concentricity (centering accuracy) to within 0.1mm.

2. Improved Stress Distribution: The specially shaped bottom of the work cylinder rationally improves the stress distribution of both the work cylinder and the hinge beam.

3. Long-Term Stable Synchronicity: An anti-scratch ring is designed on the piston, ensuring that the synchronicity of the entire machine remains stable over the long term.
