Product Description

Product Description

Spiral torsion springs are versatile components that can be found in a wide range of mechanical and electronic devices, providing a reliable means of energy storage and release through rotational movement.

1. **Torsional Deformation**: When a spiral torsion spring is twisted, it undergoes torsional deformation. This means the spring's coils twist relative to each other, storing energy in the process.

2. **Direction of Twist**: The direction of the initial winding (clockwise or counterclockwise) determines the spring's direction of winding when it is subjected to torque. This is important for applications where the direction of the return force is critical.

3. **Spring Rate**: The spring rate, or torsional stiffness, is a measure of how much torque is required to twist the spring a certain amount. It is a key parameter in the design of torsion springs.

4. **Applications**:
   - **Clocks and Watches**: They are used in the winding mechanisms of clocks and watches to store and release energy over time.
   - **Control Mechanisms**: In various control systems where a rotational force is needed, such as in steering systems or robotic arms.
   - **Toy Mechanisms**: They are used in toys that require a winding mechanism, like wind-up toys.
   - **Retractable Devices**: In devices that need to be wound up for storage and then released, such as some types of retractable badge reels or measuring tools.

5. **Design Considerations**:
   - **Wire Diameter**: The thickness of the wire used to make the spring affects its strength and the amount of energy it can store.
   - **Number of Coils**: The number of active coils (the coils that are involved in the twisting action) influences the spring's performance.
   - **Material**: The material chosen for the spring (such as stainless steel, music wire, or other alloys) affects its durability, resistance to corrosion, and ability to withstand repeated use.

6. **Load Characteristics**: The torque required to twist the spring is proportional to the angle of twist, following a relationship similar to Hooke's Law for linear springs, but adapted for rotational motion.

7. **End Treatments**: The ends of torsion springs can be designed in various ways, such as hooks, loops, or eyes, to fit the specific application.

8. **Safety**: Because torsion springs can store a significant amount of energy, they can be dangerous if they break or are released suddenly. Proper design and handling are essential to ensure safety.



 

Our production

Winding a spring is an art that begins with feeding a spring flat strip into a high-tech spring-winding machine. This semi-automatic whiz straightens out the strip material, getting it ready for its new shape. The machine then takes over, bending and shaping the strip material into the form needed, whether that's a coil, a twist, or something more complex.

Coiling is done with a spring coiler, a machine that's basically a wizard with the flat strip.  

Forming is where a spring former comes into play, bending and shaping the wire into more complex designs. This machine's got a bunch of slides that can make all sorts of bends, hoops, and radii, perfect for more intricate spring shapes.

Bending uses a CNC strip bender, a computer-controlled machine that's all about precision. It pulls the wire through a series of rollers and guides, then a movable tooling head takes over, bending the strip into the desired shape.

Once a spring is shaped, it's often heat-treated to give it that bounce-back quality. This involves heating the spring to a specific temperature for a set amount of time, then quenching or cooling it. The process can repeat, depending on the material and the desired outcome.

Grinding comes next for certain springs, smoothing down the ends so they stand upright without a wobble. This is done with a spring grinder that has two horizontal wheels that grind the spring's ends flat.

Finally, we get to coating and finishing, where springs get a little TLC. This can involve shot peening, which hardens the surface and boosts resistance to fatigue and corrosion, or plating, which adds a thin layer of metal for extra protection and can even improve the spring's appearance. Powder coating is another option, giving springs a rust-resistant finish and sometimes a pop of color.

So, that's the journey from a simple strip to a finely tuned spring, ready to bring its best to whatever product it's a part of.
 

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.
