Concering About Spring, What You Should Know?

Although the spring is a very small part of the entire manufacturing industry, the role it plays is important. We will find a variety of springs, such as extension springs used for fitness equipment, the battery springs in the remote controls, the compression springs applied in the ballpoint pen and the bicycle. But how much knowledge such as its characteristics, applications, categories and customization, etc, do you learn about these springs? This article will take you a basic introduction to the spring.

What is the Spring?

• Definition

Spring is a mechanical part using elasticity to work. The parts made of elastic materials are deformed under the action of external force and the original state is restored after removing the external force.

• Characteristics

Spring has the characteristics of elongation and compression. The rigidity of the spring can be determined according to the application. The rigidity depends on the diameter of the steel wire, the elastic modulus of the material, and the length according to the stress and expansion.

• Manufacturing materials

Spring manufacturing materials generally should have high elasticity, high impact toughness and good thermal treatment performance. The spring is commonly made of carbon spring steel, alloy spring steel, stainless spring steel, copper alloy, nickel alloys and rubber materials.

The Main Functions of The Spring

1. Control the movement of the machinery, such as the valve spring in the internal combustion engine and the control spring in the clutch.
2. Absorb vibration and impacting energy, such as the buffer springs used in the cars and trains, torsion springs used in the couplings.
3. Storing and outputting energy as power, such as clock springs, springs in firearms, etc.
4. Used as measuring components, such as the springs used in the dynamometer, spring scales, etc.
5. Tightly pressing function. You will find one of the two contacts in the switch must be equipped with springs after observing various electrical switches, which ensures that the two heads are in tight contact.
6. Buffer function. Springs are installed between the locomotive frame and the wheels, and the elasticity of the spring is used to slow down the bumping of the vehicle.

Wide Applications Of The Spring

In the development of the national industry, spring products play an important role. The expansion and the improving quality of the spring are the requirement for mechanical equipment upgrading and the improved performance of supporting the host machine. The spring is widely used in the daily product, hardware industry, automobile industry, etc, including toys, locks, staplers, ballpoint pens, fitness equipment, mattress, sofa, suspension springs for passenger cars and small vehicles, detection instruments, automatic devices, pressure meters, etc.

The Main Categories of The Spring

According to the mechanical properties, the spring can be divided into tension springs, compression springs, torsion springs and bending springs.

According to the shape, it can be divided into disc springs, ring springs, leaf springs, coil springs, truncated cone scroll springs, torsion bar springs, etc.

Compressed springs and tension springs are most widely applied, most of which can be customized by professional spring manufacturers that adopt CNC computer control or mechanical spring machinery for the manufacturing process, ensuring automatic and labor-saving production.

1. Torsion Spring

It is a spring that stands for torsion deformation. The end structure of the spring is a torsion arm that are processed into various shapes. Torsion spring uses the principle of leverage by twisting or rotating elastic material with soft and high toughness, so that it has great mechanical energy.

2. Extension Spring

It is a coil spring bearing axial tension. When there’s no load, The coils of the extension spring are generally tight without any gap.

3. Compression Spring

It is a coil spring and the used material often has a circular cross-section. It is made of rectangular and multi-steel rolls. Their shapes usually are cylindrical, conical, medium convex, medium concave. It has a stable rigidity, simple structure, convenient manufacturing process, wide application, mostly used in machinery equipment with buffer, vibration damping, energy storage and control activities functions.

4. Disc Spring

Disc spring has a strong capacity for bearing buffer and damping. Different combinations can obtain different characteristics, widely used for the pressure safety valves, automatic transfer devices, reset devices and clutch.

5. Wire Spring

The elasticity coefficient of the thickness and density of the wire spring from top to bottom, is a fixed value. This design of this spring can make the vehicle get a more stable and linear dynamic response, which is conducive to the driver and better controlling the car. It is mainly used for performance-oriented modified vehicles and competitive vehicles.

6. Lowering Spring

The lowering spring is shorter and thicker than the original spring. Installing the spring can effectively reduce the gravity of the car body and inclination when turning, making the turning more stable and smooth and improving the handling of the vehicle in curves.

Spring Customization

Customized spring and inventory spring, which is better?

When you need a precise size for the spring, a custom spring will be better. On the other hand, if you need the spring urgently, the inventory spring may be an ideal choice. If you do not need to customize it, the stock spring can reduce costs.

However, these two types of springs have cost-effectiveness. In some cases, the customized spring is actually a more cost-effective choice, because you can get the spring with accurate size for the first time.
