Types of springs and the history of springs

Spring is one of the parts that can be seen widely in all industries in different dimensions, shapes, applications and materials. Springs have the ability to be flexible and return to their original state and can withstand or transmit different forces. Springs are used in industrial machines, cars, home appliances, watches, toys, weapons and many other products.
As said; Springs are made in various shapes and sizes and are classified based on the type of shape, material, application and manufacturing method.

Springs can be divided into two general categories: bending springs and compression springs. Flexural springs bend when a force is applied to them and return to their original state when the force is removed. Compression springs are compressed when a force is applied to them and return to their original state when the force is removed. Some types of bending and compression springs are:

Spiral springs:
These types of springs are made of metal wires in a spiral shape and can be tension springs, compression springs, and torsion springs. includes These springs are used in many machines and devices. For example, spiral springs are widely used in combustion engines, car brakes, heat exchangers and suspension systems. and can withstand different bending forces. These types of springs are used in some watches, all kinds of switches, locks and electronic devices.

Ring springs:
Ring springs are made of metal wires in the form of connected rings and can bear pressure forces and quickly return the applied force. These springs are used in some chairs, sofas, mattresses and pillows.

Adjustable springs:
Adjustable springs are another type of springs that are made of metal wires in a spiral shape and have an adjustable part that can be changed by changing the length or diameter. The spring changed the amount of force they could withstand. These springs are used in some car suspension systems, sports equipment and precision tools.

The spring industry is one of the oldest and most important industries in human history, which has been developing and progressing since ancient times. The first use of springs can be seen in the construction of bone slingshots, which were made more than 60,000 years before Christ. The ancient Egyptians also used flat and bending springs in the construction of various tools.
In the 15th century, Leonardo Da Vinci used torsion springs in the design of various weapons, machines and tools. In the 18th century, Hooke's law on the relationship between force and deformation of springs was discovered, and the first spiral spring was made by Richard Tradeskin in 1763.

With the beginning of the modern era, the spring industry made significant progress with the introduction of new technologies and the establishment of larger factories. In recent years, according to domestic and foreign needs, Iran's spring industry has reached the stage of localization and industrialization and has provided quality and competitive products. Today, reliable and successful companies in the field of producing all kinds of springs Iran, and using technical knowledge, practical experience and creativity, they produce springs with various shapes, materials, dimensions and applications. These companies have customers in various industries such as automotive, oil and gas, defense, medicine, electronics, etc., and they satisfy them by providing high quality and reasonable prices.
