Spring Coiling Machines

For many industrial sectors such as automotive, motorcycle, sports, and 3C consumables, spring coiling is an important component in nearly every aspect. In this sector, a spring coiling machine is the machinery that produces coil spring, which is also known as a helical spring, and is a mechanical device which is typically used to store energy and subsequently release it. It can be used to absorb shock, or to maintain a force between contacting surfaces. 

They are normally made of an elastic material formed into the shape of a helix which returns to its natural length when unloaded. The precision and accuracy of springs affect directly the accuracy and precision of the installed machineries, realizing the machinery performance. When it’s under tension or compression, the material, that is, the wire, of a coil spring undergoes torsion. The spring characteristics, therefore, depend on the shear modulus. Spring coil machines varies from model to model, and customers all over the world prefer Taiwan’s spring coiling due to their cost-effective ratio and reasonable prices that promises the productivity for users in different industrial sectors.

Type of Metal Forming Machine

Coils & Springs

In the industry, a coil spring is a practical mechanical device which is commonly utilized to store energy and then subsequently release the energy force, to absorb shock, or to maintain a force between the contacting surfaces. They are made of an elastic material formed into the shape of a helix that returns to its natural length when it is unloaded. When it is under tension or compression, the material of a coil spring will undergoes torsion effects. As a result, the features of the spring therefore depend on the shear modulus rather than Young's Modulus, and a coil spring may also be utilized as a torsion spring. In this case the spring works as a whole is subjected to torsion about its helical axis. The composition material of the spring is thereby subjected to a bending moment, either reducing or increasing the helical radius. In this mode, it is the Young's Modulus of the material that determines the spring characteristics.

Applications

Regarding the most commonly known applications, for instance, coil springs are adopted in mechanical devices from car shocks to even watches, since coil springs are commonly called compression springs, torsion springs or helical springs based on the functional phase of their works. Springs can store energy and release it to absorb shock or maintain a force between two contacting surfaces, so a coil spring is a spiral or helix of metal wire that is usually made of steel materials for the best use of the spring structure. The spring rates is a key feature, which is the measurement of how much a coil spring can hold until it compresses 1 inch, that is around 2.54 centimeter long. The spring rate is normally specified by the manufactures which is based on their customers’ industrial demands. Here we have an example for the spring rates: If there is a spring that has a spring rate of 100, then this number means that the spring would compress 1 inch with 100lbs of loading. Based on this calculation, this is the conditions for using such springs.

Weight energy absorption

Springs are popular mechanical devices that can accept an energy or weight from one object to absorb the energy and to prevent the surface from being damaged, and compression coil springs are designed to push back on a surface when it comes into contact with it, as that offers resistance to a compressive force and are usually coiled as a constant diameter cylinder, or one that has the same size curves to its helix forms. For other model, such as expansion coil springs, which pull on two surfaces, like the spring found on screen doors that pulls it shut after it has been opened. In addition, expansion coil springs are also named as torsion springs by users.

In fact, coil springs are widely utilized in vehicle suspension system. These springs are compression springs and can differ greatly in strength and in size depending on the applications. A coil spring suspension can be stiff to soft depending on the vehicle it is applied. Coil spring can be either mounted with a shock absorber or mounted separately, depending on the design. Coil springs in trucks allow them to ride smoothly when they are unloaded and once loaded the spring compresses and become stiff. This allows the vehicle to bounce less when they are loaded. Coil spring suspension is also used high performance cars so that the car can absorb serious bumps and have low body roll. For some off-road vehicles, they are used due to their better range of travel that they allow at the wheel. These features are all different and all of them are dependent on both customers’ requests and manufacturers’ capacity.
