subject: The Design Of Compression Coil Springs [print this page] Compression coil springs usually are open-coiled helical designed springs which are designed to oppose any kind of compression. These springs are usually made of metal and are either put over a rod or fit into some form of hole. Whenever you place any type of major compression onto these springs they naturally start to push back, seeking to regain their original length.
Compression coil springs are notable for being just about the most efficient energy storage devices currently in the marketplace. The straight metal coil spring is known for being the most common of the compression springs. Other forms of configurations include the hourglass and the conical and barrel.
Take a ball point pen as an illustration, the compression coil springs that are used are incredibly tiny and finely spaced. Hour glass shaped compression springs have a very special spacing where the external circular shape is wider than the middle. The adjustable pitch spring, on the contrary, has various levels of compression throughout its body while cone shaped springs can be used for more unusual materials that a standard spring cannot support.
Compression coil springs can be found in car engines and mowers in addition to large stamping presses and household appliances. With their straight forward design and closed ends, they can better compress energy as it moves through the coil, allowing the spring to withstand the force being placed on it. Many years ago, mattresses used these kinds of springs in order to better hold body weight and contour to an individual's body when they slept.
Steel alloys, which include oil tempered low carbon and stainless steel, are often utilized to manufacture compression coil springs. This permits them to better handle pressure and heat at high stress levels. The coil itself needs to be wound around a mandrel for appropriate spacing and shape in order to obtain optimum design. The coiling is reached by using special machines just like an electrical hand drill or lathe.
During the production process for compression coil springs, the wire is manipulated to take the desired shape. If a thicker coil is desired the steel will have to be heated to become soft enough to coil. When shaped, the coils are put in the oven for heat treatment. Applying heat is used to release the stress that's put on these coils in the production phase. Based on the type of alloy used, the cooling process could take many hours.
Compression coil springs need to be strengthened to be able to withstand cracking and corroding. Because they are often an integral part of a machine's inner workings, these types of springs have to be ground and coated. In the course of grinding, both ends are concurrently finished and the body of the spring will be hammered smooth, letting it compress automatically. Coating the coil is completed using several options like dipping, painting or plating it with another metal. This protects the metal from rust.
Our industry is growing rapidly and the demand for compression coil springs increases every day. Common items including cell phones, medical equipment and computer companies are requesting smaller coils to support their devices. No matter how much our industry advances through the years, this very simple spring has helped pave the way.
