Associated Spring Raymond 105-728 Die Spring 7 in Gold

Product Description

The ASSOCIATED SPRING RAYMOND 105-728 is a heavy-duty die spring designed for use in stamping dies, metal forming tooling, and industrial press applications. It features a 1-1/2 inch hole diameter, a 3/4 inch rod diameter, and a 7 inch free length, making it suited for applications requiring high load capacity in a compact form factor. The trapezoidal wire shape delivers a maximum deflection load of 1041.6 pounds with a maximum deflection of 2.1 inches and a spring rate of 496 pounds per inch. Constructed from chromium alloy steel and finished in gold, this spring meets demanding cycle and load requirements found in production tooling environments. Tool and die makers, machine builders, and maintenance professionals install this component in die sets and press tooling.

This die spring is used in industrial stamping and forming operations where consistent spring force and long service life are critical. The gold color coding indicates a heavy load class per common die spring classification standards, allowing quick identification during tooling setup and maintenance. It is appropriate for use in both new die builds and replacement applications where a 1-1/2 inch bore and 7 inch free length are specified. Typical environments include metal fabrication shops, tool rooms, and automated press lines.

Key Features

• 1-1/2 inch hole diameter and 3/4 inch rod diameter for standard die set fitment
• 7 inch free length with 2.1 inch maximum deflection
• Maximum deflection load of 1041.6 pounds at full compression
• Spring rate of 496 pounds per inch for predictable, linear force output
• Trapezoidal wire cross-section for higher load density versus round wire springs
• Chromium alloy steel construction for fatigue resistance and long cycle life
• Gold finish for heavy-load-class identification per standard die spring color coding

Compatibility

Designed as a replacement or new-build die spring for industrial stamping and forming tooling requiring a 1-1/2 inch hole diameter, 3/4 inch rod diameter, and 7 inch free length in the heavy load class.

Installation Notes

Die springs are installed and replaced by tool and die makers or maintenance technicians working on stamping presses and forming equipment. Always de-energize and lockout the press before accessing die sets. Ensure the mating hole diameter and guide rod diameter match the spring specifications before installation. Inspect the guide rod and bore for wear or misalignment that could cause uneven loading or premature spring failure.
