Features Of Our Springs

Volute springs, often referred to as bamboo springs, embody a rectangular cross-section and conical winding. They are designed to generate substantial load capacity and energy absorption relative to their compact volume, making them ideal for shock absorber applications. Our plate thickness ranges from under 1 mm to 32 mm, with large volute springs capable of withstanding loads up to 500 kN.

Thorough Data Management

For decades, we have been crafting volute springs, receiving numerous requests for replicating existing designs. Our meticulous storage of manufacturing data enables us to consistently reproduce volute springs identical to those crafted in the past.

Key Points on Our Devotion to Handmade Springs

Tokai Spring is the sole manufacturer preserving the art of creating large volute springs. Our craftsmen shape heated metal plates into spirals, employing expertise acquired over many years to define crucial gaps essential for desired load characteristics. This process is both majestic and meticulous, demonstrating true craftsmanship. If you encounter any issues with volute springs, don’t hesitate to reach out to us at Tokai Spring.

How to Make a Volute Spring?

a. Preparations for materials
The raw materials for volute springs consist of long and thin boards.
We coil these around a coiling arbor to form the basic structure.

b. Coiling
Upon coiling the materials into a spiral, we apply high heat.
At this point, the gaps become vital.

c. After coiling
The defined gaps significantly influence the shape, dimensions, and load properties. It's during this stage that the skill and experience of our craftsmen shine through. The volute spring emerges from the coiling process with refined characteristics. If you're curious, check out our YouTube channel where you can witness the coiling of volute springs!

Volute springs are a vital component in various applications, including secateurs. Their spiral shape, crafted from spring steel, mimics a snail shell structure. This article delves into volute springs for secateurs, providing insights into their significance.

Why are volute springs important for secateurs?

Volute springs play a crucial role in secateurs, delivering the force necessary to close the blades. When the secateurs are engaged, the volute spring compresses, drawing the coils closer together. Conversely, when the secateurs are opened, the springs expand, pushing the coils apart.

The force that the volute spring exerts to shut the secateurs relies on factors like the coil count, spring material, and diameter.

Commonly utilized in diverse applications, volute springs are essential in secateurs for several reasons:

• They provide the necessary force to close the blades. Absent the volute spring, the secateurs would struggle to function effectively.
• They are durable and long-lasting. With proper maintenance, volute springs can serve for many years.
• They provide ease of maintenance. Volute springs can be effortlessly cleaned and replaced if damaged.

What are the different types of volute springs used for secateurs?

Secateurs typically incorporate two primary types of volute springs: single-coil and double-coil volute springs.

• Single-coil volute springs: As the most prevalent type, single-coil volute springs consist of a singular coil of spring steel wound around a mandrel, secured with a retaining ring or clip.
• Double-coil volute springs: In contrast, double-coil volute springs incorporate two coils of spring steel wrapped around one another, also held in place by a retaining component.

Although double-coil volute springs come at a premium compared to their single-coil counterparts, they offer superior durability and fatigue resistance, decreasing the likelihood of breakage over time.

The choice of volute spring for secateurs is application-dependent; single-coil springs are generally reserved for light-duty tasks, while double-coil springs are ideal for strenuous tasks like tree pruning.

Conclusion

Volute springs are a resilient and long-lasting solution that can endure years with adequate care. However, these springs can suffer damage from excessive loads or improper use.

For heavy-duty applications involving secateurs, it’s essential to select a volute spring tailored to meet those demands. Avoid exceeding the load capacity to prevent damage. If you suspect your secateurs' volute spring is compromised, replace it promptly, as continued use of a damaged spring may impair functionality and pose safety risks.

Overall, volute springs remain a pivotal feature in secateurs, ensuring efficient operation and performance. By adhering to straightforward guidelines, you can prolong the lifespan of your volute springs and maintain your secateurs in optimal condition.
