Gibraltar DCIM40-114 Die Spring 4-1/2 in Medium-duty Blue

Product Description

The GIBRALTAR DCIM40-114 is a medium-duty die spring designed for use in stamping dies, punch presses, and similar tooling applications where consistent, repeatable spring force is required. Built from chromium alloy steel with a trapezoidal wire cross-section, this spring delivers a maximum deflection load of 694.00 pounds across a maximum deflection of 1.82 inches. The 4-1/2-inch free length, 1-1/2-inch hole diameter, and 3/4-inch rod diameter make it a direct fit for standard die set configurations. The blue color coding indicates medium-duty load classification per industry standards. This part is installed by tool and die makers, maintenance machinists, and press technicians.

This die spring is suited for industrial tooling environments including metal stamping, forming, and punching operations. It is used in die sets where a guided spring operating over a rod or inside a bore is required to maintain consistent pressure or return force during press cycling. The medium-duty rating positions it between light and heavy classifications, making it appropriate for moderate-load tooling where controlled deflection and predictable spring rate are critical to die performance and part quality.

Key Features

• Trapezoidal wire profile increases load capacity and fatigue life compared to round wire springs of equivalent size
• Maximum deflection load of 694.00 pounds with a spring rate of 382.00 pounds per inch
• Maximum deflection of 1.82 inches with a travel to solid load of 1.8071 inches
• Chromium alloy steel construction for durability under repeated cycling
• Blue color coding identifies medium-duty load class at a glance
• Meets NAAMS, ISO 10243, and ISO 9001:2015 standards

Compatibility

Designed as a standard replacement die spring for medium-duty tooling applications requiring a 1-1/2-inch hole diameter, 3/4-inch rod diameter, and 4-1/2-inch free length configuration per NAAMS and ISO 10243 specifications.

Installation Notes

Installation is typically performed by qualified tool and die technicians or maintenance machinists during die set assembly or scheduled die maintenance. Before servicing a die set, ensure the press is fully de-energized, locked out, and the ram is blocked in the down position per applicable OSHA lockout/tagout procedures. The spring should be seated squarely over the guide rod and within the counterbore without lateral preload. Do not compress the spring beyond its rated maximum deflection during setup or operation.
