How Many Types of Coil Springs are there?

Springs are mechanical tools that wind, pull, push, lift, support, or protect. They're primarily employed in working frameworks to deliver force—compressive, torsion, or tensile—for things like lifting engine valves, opening die sets, and holding batteries in position, to mention a few. Springs are often coiled from wire, although they can also be made as cylinders, stamped steel, bags, or assemblies of other springs.

Based on their form, you can categorize springs as coil or non-coil. Coil springs have a spiral design, living up to their name. They are generally built from a single metal strand wound into a coil and spiral pattern. To create coil springs, you wrap the metal strand around a cylinder.

Whereas all coil springs have the same helical structure, a few stand out from the others thanks to particular qualities. The choice of a particular spring type will rely on the torque or force required by the user and the practical circumstances. The most typical kinds of springs are:

Torsion

 

The type of coil springs known as torsion springs is made to resist or withstand twisting motions. These springs are frequently used as clothespins and mouse traps. A torsion coil spring is used in the construction of conventional mousetraps. The spring will maintain its mechanical power when rotated around its axis. Whenever the lock is opened, it then unleashes this energy.

To store potential energy, you coil the torsion springs. Although tension springs operate at an angle and are intended to resist twisting motions rather than expanding or compressing, they adhere to Hooke's Law. Using tension springs, angular distance in radians takes the place of linear distance, and torque takes the place of force.

Torsion springs come in various forms, with uses that range from motion controls in mechanical machinery to watches and clocks. Although they can be found in-stock quantities and as part of assortment kits, torsion springs are frequently coiled to order.

Extension Springs

 

Helically wound wires are used in extension springs to produce an opposing force when expanded. The criteria are essential for the spring rate, wire diameter, helix kind; spring ends type, material, and maximum and free extended lengths. Extension springs are generally employed in production settings where a changeable, opposing friction between two parts is necessary.

Based on the holding forces necessary, a wide range of sizes, materials, and spring rates are available. You can custom make the end or typically shape them like hooks or loops.

Extension springs employ a variety of spring endpoints, many of which are specified for specific uses. The spring ends are often constructed in the loop or hook shape, although they can also be created to order. You can read more about the spring end possibilities in this linked information on the many types of extension spring ends.

Extension springs are often made of wires and aren't self-limiting; because of this, they are only suitable for uses where loss is not a severe problem. Although extension springs are frequently coiled to order, they can also be found in stock sizes and selection kits.

Spring Drawbars

 

Coil compression springs called drawbar springs have U-shaped cable forms incorporated and used in extension operations. The compression spring's positive stop characteristic and the extension spring's tension application are combined in a drawbar spring. The wire diameter,  free length, and maximum spring deflection are essential characteristics.

Drawbar springs are typically utilized when you need a tension-producing spring and require a compression spring's self-limiting property. A drawbar spring is frequently used to support porch swings because of the compression spring's self-limiting feature, preventing the spring from being loaded beyond the failure point.

Compression spring

 

The most prevalent form of springs used in the business is compression springs. The mechanical helix-shaped energy storage or release gadgets are created using spring wire. You can employ compression springs to maintain energy between two areas or absorb shock.

Because the name involves the spring's activity when a force or load is applied to it, thus the name compression springs; pitch is positioned between the coils to store energy whenever you apply a force or load to a compression spring. When the weight or force is lifted, the object releases the stored energy and resumes its original shape. It "springs back," in other terms.

 

Wire diameters for compression springs typically range from 0.006 to 1.250 inches. Around 0.06 to 0.6 are the sizes of more common stock springs. Compression springs are used in various devices that need a bouncing action, including pogo sticks, pens, and many buttons.

Volute Springs 

 

Volute springs are helical spirals made of flat metal strips usually used for compression purposes. The essential criteria are the diameter, intended application, material, stroke, and end attachment type.

Volute springs are typically employed when a compression spring with a long fatigue life or high repeatability of the spring force is needed. Based on the use, the force needed, and materials, they are available in various sizes. 

Volute springs can be single-ended or double-ended. The compression spring seen in pruning shears or premium nail clippers is one prominent application of the volute spring.

Take away

 

A mechanism for storing mechanical potential energy is the coil spring. In the modern world, springs are widespread and used in almost every industry. Many brands design and produce standard, customized springs for commercial and industrial applications. Contact professionals, and they'll be pleased to answer your question about what a coil spring is if you still have one.

You can order any of the spring kinds as a stock spring or customized and bought as a one-of-a-kind item to meet particular requirements. At GL Metal, you may locate any spring required, including compression, torsion, and extension springs. Along with a wide selection of torsion and tension springs, they stock many compression spring models. Start using one of their spring discovery tools to get the ideal spring right now.
