Wire springs, Flat springs
Springs are mechanical devices that pull, push, wind, support, lift, or protect. Springs are commonly wound from wire, but can be machined from solid steel, built as cylinders, formed as bags, stamped from steel, or assembled from other springs. Ordinary wire springs exhibit a force whose magnitude increases linearly as the spring is pushed, pulled, or twisted. Springs are often made to order using dedicated wire winding machines that can wind wire through a given number of turns over a specific length to produce the necessary force constant for the particular application.
Torsion types of springs are used to store twisting force. They are used where rotational motion less than 360ยบ is required.
Torsion type helical spring are used in:
Compression Springs are designed to operate in compression load. IN Compression Helical Springs, Helical coils are spaced at relatively larger distance. When a compression force is applied, their length reduces.
Compression Helical Spring Applications include:
Extension Springs are helically coiled wires designed to provide an opposing force when stretched. Key specifications include the spring rate, helix type, spring ends type, wire diameter, material, and free and maximum extended lengths.
Extension Spring Applications include:
