Spring is an elastic mechanical parts to work . Spring is just an accumulator , which has the function of storing energy , but can not release energy slowly , slowly release to achieve this function should rely on " Spring + large transmission ratio mechanism " to achieve common in mechanical watches . Early spring there long before the application of the ancient bow and crossbow is spring two broad sense. Spring inventor in the strict sense should be British scientist Hooke (RobertHooke), although at that time there have been a helical compression spring and widely used, but Hooke proposed " Hooke 's Law" - the spring elongation and suffered size is proportional to the force , is based on this principle, in 1776 , the use of a helical compression spring balance advent of spring . Soon, according to the principle of making springs designed for clocks are also Hooke himself invented. The accord " Hooke 's Law " in the spring is a spring in the true sense . French disc springs Belleville invention is material or forging blanks made of spring washers truncated conical section of the metal plate . After the emergence of modern industry , in addition to disc springs also appeared gas springs, rubber springs, spiral spring , die springs , stainless steel spring, air springs, and other new memory alloy spring spring .
Like most other basic mechanisms exist Bronze Age metal spring long . Even metal, wood is used as a structural member flexible bows and military catapult . In precise clocks Renaissance , makes precision springs first became inevitable. Fourteenth century saw a revolutionary astronomical clock accurate navigation development. Explore and conquer the world of European colonial powers continue to provide power watchmaker " Science and Art . Another area of firearms , and promote the development of the spring . Advent of the industrial revolution of the eighteenth century the occasion , presented to a large , accurate and inexpensive spring . Given the watchmaker ' spring often hand-made , mass-produced material for spring piano wire or similar material . advanced manufacturing methods to make today's spring is everywhere . computer control lines and plate bending machine allows custom spring processing, obviously this is a special-purpose machinery.
