Product Description

Product Description

 

 

A flat spiral spring is a type of spring that is made by winding a flat strip of material, such as metal  , into a spiral shape. Unlike traditional coil springs, which are wound into a cylindrical shape, flat spiral springs have a flat profile.

These springs are often used in applications where space is limited or where a low profile is desired. They can be found in various devices such as clocks, watches, measuring instruments, and electrical contacts. Flat spiral springs offer advantages such as uniform force distribution, compactness, and the ability to store energy efficiently.

STRUCTURE OF SPIRAL SPRINGS:

A spiral spring is composed of a thin strip with a rectangular cross-section, wound in a spiral shape. The inner end of the wound strip is fixed to the center arbor, while the outer end is clamped to the retaining drum. When the arbor rotates, the spring winds up.

WORKING PRINCIPLE:

As the arbor rotates, the spring winds up, storing energy in the process. This stored energy is then released as mechanical torque through the drum when the spring unwinds due to rotation. The strip used in spiral springs is made of high-quality steel. Its thinness allows for high flexibility, enabling the arbor to have a larger angular deflection. In many applications, the arbor's angular deflection can span several dozen revolutions, resulting in the storage of a significant amount of energy. In many cases, the drum is integrated with a gear. The energy released by the rotation of this gear is then transferred to another gear, which drives a specific mechanism.

Parameters:
 

Here are some of the typical parameters:

1. Material: Steel is the most common material used for flat spiral springs due to its excellent strength, durability, and resilience.

2. Thickness: The thickness of the steel strip used to make the spring affects its stiffness and load-bearing capacity. Thicker strips provide greater stiffness and support heavier loads.

3. Width: The width of the steel strip determines the contact area with the mating surfaces and affects the distribution of force. Wider strips can handle higher loads but may require more space.

4. Outer Diameter (OD): The outer diameter of the spiral spring defines the overall size of the spring. It influences the space required for installation and the available deflection.

5. Inner Diameter (ID): The inner diameter is the diameter of the central opening of the spiral. It affects the spring's flexibility and deflection characteristics.

6. Number of Turns: The number of turns or coils in the spiral spring determines its overall length and the amount of deflection it can undergo.

7. Pitch: Pitch refers to the distance between adjacent coils. It affects the spring rate and the amount of force required for a given deflection.

8. Ends: The ends of the spiral spring can be customized for specific applications. Common end types include straight ends, hooked ends, or closed and ground ends.

9. Load Capacity: This parameter defines the maximum force that the spring can support without permanent deformation.

10. Fatigue Life: Fatigue life refers to the number of cycles (compressions and releases) that the spring can withstand before failure, usually expressed in terms of millions of c

 

Our production

 

Our quality control

Quality control during the spiralspring production process mainly includes the following aspects:

Material selection: The material of the spiral spring needs to have good elasticity and toughness to ensure the durability and stability of the spring. Therefore, the selection and inspection of materials during the production process is very important.

Production process: During the production process of spiral springs, parameters such as the size, shape and wire diameter of the spring need to be strictly controlled to ensure the performance and quality of the spring.

Heat treatment: spiral springs usually require heat treatment after production to enhance their elasticity and wear resistance. In this process, parameters such as temperature and time of heat treatment need to be strictly controlled.

Inspection: After the spiral spring is produced, it needs to undergo comprehensive quality inspection, including hardness test, elasticity test, fatigue test, etc., to ensure that the performance of the spring meets the requirements.

Traceability mechanism: In the production process of scroll springs, it is also necessary to establish a complete product traceability mechanism so that when quality problems occur, the causes can be found in time and improvements can be made.

In general, quality control in the spiral spring production process is a comprehensive task, which requires comprehensive control from material selection, production process, heat treatment, testing and traceability to ensure the quality and safety of scroll springs. The performance meets the requirements.
