WT-60/80BS Mattress bonnell spring coiling machine 

A Bonnell coiling spring machine is a type of industrial machine used to manufacture Bonnell springs, which are commonly used in the production of mattresses, furniture, and bedding products. The Bonnell spring is known for its hourglass shape, providing good support and durability, which makes it a popular choice in the bedding industry.

Key Features of a Bonnell Coiling Spring Machine:

1. Automatic Coiling: The machine automatically coils wire into the characteristic hourglass shape of the Bonnell spring.
2. Wire Feed: It typically feeds wire through a series of rollers or guides, which then form the wire into coils with precise tension and shape.
3. Spring Formation: The machine is designed to create the precise dimensions required for the springs, including the correct pitch (spacing between coils), wire diameter, and overall spring height.
4. Welding: After the coils are formed, the ends of the wire are typically welded to secure the coils in place. Some machines have built-in welding capabilities, while others may require a separate welding machine.
5. Customization: Some machines allow the user to adjust parameters such as coil diameter, pitch, and wire tension to produce springs for different applications (e.g., softer or firmer mattresses).
6. Speed and Efficiency: Modern machines are highly automated and can produce springs at a high rate of speed, making them ideal for mass production of springs for large-scale bedding manufacturers.
7. Control Systems: Many machines come with advanced computer control systems to ensure accuracy in the coiling process and to monitor the quality of the springs being produced.

Advantages of Bonnell Coiling Spring Machines:

• High Production Efficiency: Once set up, these machines can produce a large number of springs in a relatively short amount of time.
• Consistent Quality: The automation and precise control over the coiling process ensure consistent quality and uniformity of the springs.
• Cost-Effective: Given their efficiency and the reduction in labor costs, these machines are cost-effective for large-scale manufacturers.
• Versatility: While the primary application is for mattress springs, Bonnell coiling machines can also be used to produce other types of springs, such as those used in seating or automotive applications.
