When using a spring machine to produce springs, special attention should be paid to the following aspects to ensure the quality, stability and service life of the finished product:

1. Material Considerations

1. Choose the Right Material

• Common materials include high-carbon steel (e.g., 65Mn, SK5) and stainless steel (e.g., SUS301, SUS304).

• The material must have excellent elasticity, fatigue strength, and corrosion resistance.

2. Material Treatment Requirements

• Surface oxides, burrs, and oil must be removed before processing.

• Thickness and width must be uniform and within tolerance limits.

2. Spring Machine Setup and Adjustment

1. Tension Control

• Mainsprings require highly consistent tension; a tension control system must be used to ensure uniform force throughout the process.

2. Precision Feeding

• Ensure stable feeding length and speed to avoid accumulated errors that may affect spring performance or shape.

3. Forming Die Adjustment

• Dies must be precisely adjusted to match the spring dimensions.

• Prevent issues such as wire jumping, edge folding, or misalignment during coiling.

4. Winding Direction Selection

• Choose single-direction or bi-directional winding based on the specific design of the mainspring.

3. Heat Treatment

1. Stress Relief Annealing

• After forming, springs must undergo low-temperature annealing to eliminate internal stress and prevent deformation.

2. Quenching and Tempering (if required)

• Enhances strength and fatigue life. Parameters must be set according to the material and application.

4. Inspection and Quality Control

1. Dimensional Inspection

• Check critical dimensions such as outer diameter, inner diameter, thickness, and total length.

2. Performance Testing

• Test for torque, tension, and rebound force to ensure they meet design specifications.

3. Fatigue Testing

• Perform life cycle testing on samples to confirm long-term durability.

5. Safety and Maintenance

1. Operator Training

• Operators must be well-trained, especially in handling automated coiling systems.

2. Regular Equipment Maintenance

• Regularly lubricate, clean, and inspect key components such as guides and dies for wear.

3. Prevent Material Recoil Injuries

• Mainsprings store mechanical energy; operators should wear protective gear to prevent injury from sudden recoil.
