Springs . There is no doubt the importance of springs in solving problems and needs that arise daily in the lives of users and for that there are companies dedicated to the manufacture of springs in stainless , medium and high carbon or alloy steels .

Its use
Springs are used to weigh objects on scales , to store mechanical energy , such as on winding watches ; They are also used to absorb impacts and reduce vibrations, like those used in car suspensions . The concrete shape of a spring depends on its use; in fact, the service conditions of the springs are many times extremely severe, either due to the loads and types of stresses they will endure, or due to the temperatures, corrosive media, vibration , etc., to which they may be subject.
Types
We generally consider two types of springs: helical or coiled springs and semi-elliptical springs ; the former comprise the following subdivisions:
- Compression spring
They are open coil or spiral , designed to withstand compression and shock efforts, this property that allows them to decrease their volume when the pressure exerted on them is increased, making them the most efficient energy storage devices available; they represent the most common configuration used on the market today. Its manufacture is made from round wire , and its shapes can be: cylindrical, conical barrel , convex and other types of profile.
- Extension spring
They are characterized by being a closed coil or spiral , intended to withstand tensile stresses when subjected to the action of opposing forces that attract it, a multitude of configurations and hook length can be used, where the united turns supply the initial tension in the spring to help manipulate load and speed .
Its applications range from small medical equipment to brake springs for heavy machinery or automotive .
- Torsion spring
Their turns are generally closed, they are intended to withstand lateral stresses or helical deformation when a pair of parallel forces of equal magnitude and opposite direction is applied to it, offering resistance to the application of external torque.
The torsion springs special type include double twist and having a space between the turns to minimize friction .
Diversity
They are made from round wire, but do not have a wound body. These incorporate hooks and folds that act as fixing points in the application.
They are designed to perform functions that go beyond those of a normal spring, for example, to act as locks or to hold a part in place.
