Advantages of Volute Springs

 
 
01
 

Progressive Load-Deflection Rate:

Unlike cylindrical springs, which exhibit a linear load-deflection relationship, volute springs provide a progressive spring rate. This means that the force required to compress the spring increases as the compression distance increases. This progressive nature is particularly beneficial in applications where a controlled, soft initial load is required, followed by a stiffer response at higher loads.

 
02
 

Space Efficiency:

The conical shape of volute springs allows them to occupy a relatively small footprint compared to cylindrical springs of equivalent load capacity. This makes them ideal for applications where space constraints are a concern.

 
03
 

High Load Capacity:

Volute springs can withstand significant compressive loads due to their optimized geometry and material selection. This makes them suitable for applications that demand high load-bearing capabilities.

Manufacturing Process of Volute Springs
 

The manufacturing of volute springs involves several steps to ensure precision and quality. Here is an overview of the typical manufacturing process:


Material Selection: The first step in manufacturing a volute spring is selecting the appropriate material. Steel is commonly used due to its strength and durability. The material is chosen based on factors such as load requirements, temperature tolerance, and corrosion resistance.

 

Strip Formation: The selected material is then processed to form a flat strip of the desired dimensions. This can be achieved through techniques such as cutting, rolling, or stamping.

 

Winding: The flat strip is wound in a spiral shape using specialized machinery. The number of turns and the pitch of the spiral are determined by the design requirements and the intended application.

End Formation: The ends of the volute spring are shaped and formed to create loops or hooks. This step enables easy attachment and installation of the spring.

 

Heat Treatment: To enhance the spring's mechanical properties, a heat treatment process may be applied. This process involves subjecting the spring to controlled heating and cooling cycles to improve its strength and flexibility.

 

Surface Treatment: Depending on the application and desired aesthetics, the volute spring may undergo surface treatments such as painting, plating, or coating to enhance its corrosion resistance and appearance.

 

Quality Control: Throughout the manufacturing process, rigorous quality control measures are implemented to ensure that the volute springs meet the specified standards and requirements. This includes dimensional checks, load testing, and visual inspections.

FAQ

 

 

Q: I need a customized fastener, but it's not on your website. What do I do?

A: Please send us your request with detailed drawings or photos, then we will make the quotation for you accordingly.

Q: In general, how long can delivery be made after receiving an order?

A: Regular orders can be completed and shipped within 15-20 working days after receiving the deposit and confirming product details.

Q: During the product usage process, if we encounter technical problems, can you provide technical support?

A: Sure. We have a professional technical team that can provide you with technical consultation and guidance through methods such as telephone, email, or video conference.

Q: What is the packaging method of the product?

A: 50KG bag and pallet.

Q: What is the difference between conical and volute springs?

A: Volute compression springs have a cone shape that is similar to conical compression springs. The difference between them is the form of the materials used to make them. Volute compression springs, unlike other springs, do not use curled or swirled wire.

Q: How does a volute spring work?

A: A volute spring is a compression spring in the form of a cone (a volute). Under compression the coils slide over each other, affording a long travel. The result is more stable and powerful than any leaf, coil, or torsion bar spring in the same volume.

Q: How to make a volute spring?

A: Cold Coiling: The most common method for manufacturing volute springs involves coiling wire around a mandrel to achieve the desired shape. The spring is then heat-treated to enhance its strength and durability.

Q: When to use conical springs?

A: Conical compression springs are used in applications that require additional stability and resistance to buckling under load, as a large base provides good stability during compression and relaxation of the spring.
