Constant force springs for tension and compression forces Constant force springs are characterized by a very uniform force-displacement curve. This curve can be adjusted within defined limits to the specific application. The machinery for production is developed and manufactured internally by KERN-LIEBERS.Custom manufacturer of constant force springs in the form of flat strip and wire. Stainless steel, copper, alloy and alloy steel materials used. Spring end types include closed end ground, closed end unground, double torsion, straight offset, squared and hinge.Nov 07, 2016 Die springs are compression springs, but differ from most in that they are a type of high force compression spring. Engineered to consistently give predetermined pressure at a given compression, die springs are well-suited for applications involving high loads or extreme conditions, like high temperatures.A die spring is commonly used in clutches, brakes and other heavy machinery applications. Use precision compression springs and conical compression springs in mechanical applications like welding, valve and pipe-fitting and automotive engine systems. Stock up on compression and die springs from Grainger in the types and sizes you need.Alibaba.com offers 792 constant force compression springs products. About 94% of these are Springs.

Constant Force Compression Spring, Constant Force
Hershey Constant Force Spring A constant-force spring is a spring for which the force it exerts over its range of motion is a constant. Generally constant-force springs are constructed as a rolled ribbon of spring steel such that the spring is relaxed when it is fully rolled up.
Constant Force Springs The extension type of constant force spring represents the most basic, yet most versatile, type of constant force spring. It is a pre-stressed flat strip of spring material which is formed into virtually constant radius coils around itself or on a drum.
Die Springs Because of their ability to handle heavy-duty compression applications, die springs can be used in any heavy-load and heavy-stress application, including aircraft
The spring constant is also known as your spring rate or compression spring rate. How to measure spring rate: enter your inputs into our spring force calculator and review your answers. Outputs include spring ratings and spring constant. Spring ratings are a constant, example: If your spring rate is 10 lbsf/in then it will take you 10 lbsf to
Elastic limit is maximum compression a die spring can handle before deformity. Preload is the distance of free length reduced by a consistent load on the spring. Operating travel is the distance subtracted from the spring length after operating load has been applied.
Constant Force Springs for Application Enhancement. Constant force springs have the ability to extend across their performance range, while maintaining a constant force and position. The constant force allows the spring to resist uncoiling in an application, and remain tightly wrapped. SMSC designs and provides standard and custom constant
This calculator computes the force exerted by a compression spring (with a known spring constant k) when given the spring length before and after loading. Calculator for Finding Forces in Compression Springs
HEFTY ™ Die Springs. HEFTY™ Die Springs are heavy duty metal compression springs manufactured using round wire, specifically designed to be used as Die Springs or as heavy duty coil springs in any heavy stress, heavy load application. Lee Spring offers FIVE different types of HEFTY™ Die Springs, based on Load, for applications requiring Medium Duty up through Extra Heavy duty Die Springs.
Jun 10, 2014 Die springs are sometimes referred to as ‘high force compression springs’ or ‘heavy duty compression springs’, and that really goes a long way towards describing how the two products differ. They excel even when under significant environmental stress, and they usually use rectangular wire (as opposed to the round wire used in most ‘traditional’ compression springs).
Spring Design Menu - Spring Suppliers and Manufacturers. This calculator will determine the spring rate constant related to a compression spring from basic geometry and material data input. Default units are shown in inches, etc however SI (metric) can be used. This equation will determine (estimate) the Spring Rate (k) of a compression spring.
Variable Rate: These springs offer a constant, or uniform pitch, and have an increasing force rate instead of a constant force rate (regular compression springs). The larger coils gradually begin to bottom as a force is applied. A variable pitch can be designed to give a uniform rate if necessary.
A constant force spring is a roll of pre stressedstrip which exerts a nearly constant restraining force to resist uncoiling (Figures 1 and 2). The force is constant because the change in the radius of curvature is constant. This is true if the change in coil diameter due to buildup is disregarded.

Compression Springs. Compression Springs are open-coil helical springs wound or constructed to oppose compression along the axis of wind. Helical Compression is the most common metal spring configuration. Learn more about Compression Springs.
Constant Force Springs
A constant force, or “clock” spring, is a roll of prestressed strip which exerts a nearly constant restraining force to resist uncoiling. The force is constant because the change in the radius of curvature is constant. This is true if the change in coil diameter, due to buildup, is disregarded.
Calculating Constant Force on a Coil Compression Spring
Definition. The calculation of the amount of constant force it takes a coil compression spring to compress down to a loaded height is calculated by multiplying the force by the distance the coil compression spring is expected to travel. The unit of measurement for constant force is lbf/in which stands for pounds of force per inch.
Cone shaped compression springs have a spring radius that decreases towards the end of the spring. This is a common shape used for battery springs. Hour glass compression springs taper tighter towards the center and the outer coils have a larger diameter. Barrel shape compression springs have a design that is reduced at the ends and wider in the center.
