Cage Body: Length Range 300-1500 mm, Diameter Range 200-800 mm

Component Specifications

Definition

The Cage Body is a cylindrical or barrel-shaped structural component that forms the outer shell of a Pressing Cage assembly. It provides containment for pressing elements (such as rollers, plates, or dies), maintains alignment under operational loads, and transfers mechanical forces during pressing operations. Designed to withstand high compressive and torsional stresses while maintaining dimensional stability.

Working Principle

The Cage Body operates by containing and guiding pressing elements within its structure. During operation, it maintains geometric integrity while transmitting mechanical forces from the pressing mechanism to the material being processed. The body's design ensures uniform pressure distribution and prevents deformation under load.

Materials

High-strength alloy steel (typically AISI 4140 or equivalent), heat-treated to HRC 28-32 for optimal strength-to-toughness ratio. May include wear-resistant surface treatments like nitriding or hard chrome plating for extended service life.
