What is the principle of a spring machine?

Industry News-

A spring machine is a mechanical device used to make springs, and its working principle is based on the manufacturing process of springs. Spring is an elastic element that can store energy and return to its original shape when released. The following is the basic working principle of a spring machine:

1. Material supply: The spring machine needs to supply the material (usually metal wire or rod) into the machine.

2. Wire straightening: Before making the spring, the wire needs to be straightened to ensure the accuracy and performance of the spring.

3. Wire feeding: The wire is fed into the spring forming area through the wire feeding mechanism.

4. Spring forming: In the spring forming area, the wire is wound into the required spring shape. This process can be achieved in different ways, such as winding, torsion, compression, etc.

5. Dimension control: During the spring forming process, the machine controls the parameters of the spring such as diameter, wire diameter, number of turns, free length, total length, etc. to meet the design requirements.

6. End Treatment: The ends of the spring may require special treatment, such as sharpening, chamfering, welding, etc., to suit specific application requirements.

7. Heat Treatment: To improve the performance of the spring, such as increasing elasticity and durability, the spring may need to undergo a heat treatment process, such as quenching and tempering.

8. Surface Treatment: After the spring is formed, it may also need surface treatment, such as electroplating, spraying, or oiling, to provide additional protection and performance.

9. Quality Inspection: After the spring is manufactured, it will be quality inspected to ensure that it meets the design and performance standards.

10. Packaging and Storage: Finally, qualified springs will be packaged and stored, ready for shipment or further use.

Spring machines can be manually operated or automated. Automated spring machines can improve production efficiency and spring consistency. Different types of spring machines are suitable for manufacturing different types of springs, such as compression springs, extension springs, torsion springs, and flat scroll springs.
