Introduction to Four-Column Cold Extrusion Forming Hydraulic Press

The four-column cold extrusion forming hydraulic press is specifically designed for cold extrusion, a metal plastic forming process. It is a key piece of equipment in modern manufacturing for producing high-precision, high-strength, and complex parts. Below, Jianlong Hydraulic Technology will share a summary of its core features and provide a clear explanation using a typical technical parameter table for reference.

1. Core Structure: Four-Column Guiding

The equipment adopts a classic three-beam, four-column structure (the upper crossbeam, movable crossbeam, and lower worktable are connected by four columns). This structure provides extremely high rigidity and resistance to eccentric loads, accurately guiding the slider movement (accuracy up to ±0.03mm), which is crucial for handling the enormous asymmetric lateral forces during cold extrusion.

2. Working Principle: High-Pressure Hydrostatic Forming

The hydraulic system drives the main cylinder piston downwards, applying powerful static pressure (nominal force typically 63 tons to over 1000 tons) through the mold to the metal billet (such as steel, aluminum, and copper) at room temperature. This causes plastic flow under triaxial compressive stress, filling the mold cavity and forming a complex part in one step.
