Gibraltar DCIB40-64 Die Spring 2-1/2 in Extra Heavy-duty

Product Description

The GIBRALTAR DCIB40-64 is an extra heavy-duty die spring designed for use in stamping dies, press tooling, and industrial forming equipment. Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers a maximum deflection load of 1,863 pounds and a spring rate of 2,586 pounds per inch. The 2.5-inch free length compresses to a solid length at 0.7008 inches of travel, giving technicians a precise, predictable stroke in tight tooling setups. The yellow color coding identifies this spring as an extra heavy-duty grade per industry standards. Toolmakers, die setters, and maintenance machinists are the primary installers.

This die spring fits applications where high compressive loads and controlled deflection are critical, including metal stamping dies, injection mold tooling, and heavy-duty industrial presses. The 1.5-inch hole diameter accepts guide posts, and the 0.75-inch rod diameter is compatible with standard die rod sizing. Its chromium alloy steel construction handles the cyclic fatigue demands of production press environments. The DCIB40-64 ships as a single-unit package, making it straightforward to spec and order as a direct replacement in existing tooling.

Key Features

• Extra heavy-duty rating with a maximum deflection load of 1,863 pounds (8,290.35 N)
• Trapezoidal wire cross-section maximizes load capacity within the coil envelope
• Chromium alloy steel construction for high fatigue resistance in cyclic press applications
• Yellow color coding for quick visual identification of extra heavy-duty grade
• Maximum deflection of 0.72 inches (18.29 mm) with a spring rate of 2,586 pounds per inch
• Meets NAAMS, ISO 10243, and ISO 9001:2015 standards

Compatibility

Designed as an OEM-style replacement die spring for stamping die and press tooling applications requiring a 1.5-inch hole diameter, 0.75-inch rod diameter, and 2.5-inch free length in an extra heavy-duty yellow-grade coil spring.

Installation Notes

Die spring replacement is typically performed by toolmakers or maintenance machinists during die maintenance or rebuild. Relieve all press pressure and lock out the press ram before removing or installing any die components. Ensure the guide post and rod diameters match the spring bore and rod specifications before installation to prevent coil binding or lateral loading. Inspect the spring seat surfaces for wear or damage that could cause uneven load distribution across the coil.
