Product Description

Product Description

 

A flat spiral spring is a type of spring that is made by winding a flat strip of material, such as metal  , into a spiral shape. Unlike traditional coil springs, which are wound into a cylindrical shape, flat spiral springs have a flat profile.

These springs are often used in applications where space is limited or where a low profile is desired. They can be found in various devices such as clocks, watches, measuring instruments, and electrical contacts. Flat spiral springs offer advantages such as uniform force distribution, compactness, and the ability to store energy efficiently.

STRUCTURE OF SPIRAL SPRINGS:

A spiral spring is composed of a thin strip with a rectangular cross-section, wound in a spiral shape. The inner end of the wound strip is fixed to the center arbor, while the outer end is clamped to the retaining drum. When the arbor rotates, the spring winds up.

WORKING PRINCIPLE:

As the arbor rotates, the spring winds up, storing energy in the process. This stored energy is then released as mechanical torque through the drum when the spring unwinds due to rotation. The strip used in spiral springs is made of high-quality steel. Its thinness allows for high flexibility, enabling the arbor to have a larger angular deflection. In many applications, the arbor's angular deflection can span several dozen revolutions, resulting in the storage of a significant amount of energy. In many cases, the drum is integrated with a gear. The energy released by the rotation of this gear is then transferred to another gear, which drives a specific mechanism.

Parameters:
 

Here are some of the typical parameters:

1. Material: Steel is the most common material used for flat spiral springs due to its excellent strength, durability, and resilience.

2. Thickness: The thickness of the steel strip used to make the spring affects its stiffness and load-bearing capacity. Thicker strips provide greater stiffness and support heavier loads.

3. Width: The width of the steel strip determines the contact area with the mating surfaces and affects the distribution of force. Wider strips can handle higher loads but may require more space.

4. Outer Diameter (OD): The outer diameter of the spiral spring defines the overall size of the spring. It influences the space required for installation and the available deflection.

5. Inner Diameter (ID): The inner diameter is the diameter of the central opening of the spiral. It affects the spring's flexibility and deflection characteristics.

6. Number of Turns: The number of turns or coils in the spiral spring determines its overall length and the amount of deflection it can undergo.

7. Pitch: Pitch refers to the distance between adjacent coils. It affects the spring rate and the amount of force required for a given deflection.

8. Ends: The ends of the spiral spring can be customized for specific applications. Common end types include straight ends, hooked ends, or closed and ground ends.

9. Load Capacity: This parameter defines the maximum force that the spring can support without permanent deformation.

10. Fatigue Life: Fatigue life refers to the number of cycles (compressions and releases) that the spring can withstand before failure, usually expressed in terms of millions of c

2. Stainless Steel: Stainless steel is prized for its corrosion resistance, making it ideal for spiral springs used in harsh or corrosive environments. It also possesses good strength and elasticity properties, ensuring reliable performance.

3. High Carbon Steel: High carbon steel is another viable option for spiral springs, offering superior strength and hardness. It provides good spring properties and can withstand heavy loads, making it suitable for demanding applications.

4. Alloy Steels: Alloy steels, such as chrome vanadium or chrome silicon, offer enhanced mechanical properties compared to plain carbon steels. They provide excellent strength, toughness, and fatigue resistance, making them suitable for high-performance spiral springs.

5. Non-Ferrous Alloys: Some applications may require spiral springs made from non-ferrous alloys like bronze or brass. These materials offer good corrosion resistance and thermal conductivity, although they may have lower strength compared to steel alloys.

The choice of raw material depends on factors such as the application requirements, operating conditions, desired performance characteristics, and budget constraints. It's essential to select a material that can withstand the intended load, environmental conditions, and potential wear factors for optimal performance and longevity of the spiral spring.

Production facilities

By following these key points and maintaining strict quality control standards, we can produce high-quality spiral springs that meet the needs of various industrial applications.

1. **Material Selection**: Choose the appropriate raw material based on factors such as application requirements, load-bearing capacity, environmental conditions, and budget constraints. Common materials include spring steel, stainless steel, high carbon steel, alloy steels, and non-ferrous alloys like bronze or brass.

2. **Wire Forming**: The selected material is formed into wire of the desired diameter and shape. Precision wire forming machinery is used to ensure consistent dimensions and quality.

3. **Coiling**: The wire is fed into a coiling machine, where it is wound around a mandrel or central axis to create the spiral shape of the spring. The coiling process must be carefully controlled to achieve the desired pitch, diameter, and coil spacing.

4. **Heat Treatment**: After coiling, the springs are subjected to heat treatment to improve their mechanical properties, such as hardness, strength, and elasticity. This process typically involves heating the springs to a specific temperature and then quenching or tempering them to achieve the desired material properties.

5. **Surface Treatment**: Depending on the application requirements, the springs may undergo surface treatment processes such as shot peening, grinding, or polishing to improve surface finish, remove burrs, and enhance fatigue resistance.

6. **End Forming**: The ends of the springs are formed into various configurations to facilitate attachment to other components. Common end forms include closed loops, hooks, or threaded ends.
