Die springs - ISO

All of the manufacturing steps are closely monitored by rigid quality controls, inspection and testing to ensure that the long services life engineered into every die spring in constant.

Spring manufactured in accordance with ISO 10243.
Green = Light Duty
Blue = Medium Duty
Red = Heavy Duty
Yellow = Extra Heavy Duty
DIE spring features
  • Superior materials & Wire Profile
  • All Raymond die springs are made from high tensile strenght chromium alloy steels
  • Optimal wire cross section
  • Spring ends are ground square
  • Other raw materials are available for special conditions and environments
Dimensional Consistency
  • Dimension requirements remain consistent and measurably the same from one batch of springs to the next.
Longer Spring Life
  • Engineered to better withstand shock loading
  • Designed to endure constant high-speed deflections
  • Shot-peened to increase fatigue life
  • Less downtime
Excellent Deflection
  • Springs provide greater available travel to solid
  • More travel in each spring
Common DIE Spring Terminology

Hole Diameter: This identifies the outside diameter (Do) of the die spring. Raymond die spring are available in eight different hole sizes matched to standard drill sizes. Each spring is made to fit in the hole, so the Do of the spring is actually less than the hole diameter.

Rod diameter: This is a nominal identification of the inside diameter (Di) of the die spring. raymond die springs are available in eight different hole size mached to standard stripper bolts. Each spring is made to fit over the rod, so te Di of the springs is actually greather than the rod diameter.

Free Lenght: The lenght of a die spring before it is subject to any operating force to load.

Preload: The distance to free lenght of the die spring is reduced by the pressure of assembled tool.

Operating travel: The distance which is subtracted from the spring lenght after operating force has been applied.

Deflection: The amount of change in spring lenght after operating force has been applied. The compressed lenght is computed by subtracting the initial compression and the operating travel from the free lenght.

Solid height: The lenght of a spring when it is compressed by enought load to bring all the coils into contact with each other.

Load: This is the force built up by compressing the spring. Load is expressed in terms of total Newtons, which is the load on the spring per a specific unit of deflection. Load is generated and stress on the coils increases.
