Gibraltar DCIM20-76 Die Spring 3/4 in Medium-duty Blue

Product Description

The GIBRALTAR DCIM20-76 is a medium-duty die spring designed for use in stamping dies, tooling fixtures, and industrial press applications. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers consistent force and long service life under repetitive load cycles. It features a 3/4-inch hole diameter, a 3/8-inch rod diameter, and a 3-inch free length. Maximum deflection load is 179.00 pounds, with a maximum deflection of 1.22 inches. The blue color coding identifies it as a medium-duty spring per standard die spring classification. Toolmakers, die setters, and industrial maintenance technicians are the primary installers.

This die spring is suited for use in stamping and forming dies, injection mold tooling, and general industrial clamping and stripping applications. The 3/4-inch hole diameter and 3/8-inch rod diameter make it compatible with standard die set configurations requiring medium-duty return force. It is sold individually and is a direct replacement for worn or failed springs in existing tooling setups. Applications span both light production and high-cycle manufacturing environments where consistent spring rate and load repeatability are required.

Key Features

• Chromium alloy steel construction for durability under high-cycle fatigue conditions
• Trapezoidal wire cross-section provides higher load capacity relative to round wire at the same outer diameter
• Blue color coding identifies medium-duty classification per standard die spring conventions
• Spring rate of 147.0 lb per inch for predictable, consistent deflection behavior
• Meets NAAMS, ISO 10243, and ISO 9001:2015 standards
• Maximum deflection load of 179.00 pounds with 1.22 inches of travel

Compatibility

Designed as an OEM-style replacement die spring for standard tooling and stamping die applications requiring a 3/4-inch hole diameter and 3/8-inch rod diameter in a medium-duty blue spring classification.

Installation Notes

Die spring replacement is typically performed by toolmakers or die maintenance technicians. Always relieve all press pressure and lock out the press before servicing any die components. Ensure the rod diameter and hole diameter of the replacement spring match the existing die set precisely before installation. Do not compress the spring beyond the rated maximum deflection to avoid permanent set or premature failure.
