Characteristic:

Constant force (constant force) springs are rolled by stainless steel strips. The high-strength steel strips are shaped by specific production spring equipment. When the external force straightens them, the spring will naturally wind back and produce elasticity, but it reaches us The goal can return to the starting point we specified after being shifted.

Advantage:

The advantages of constant force spring over traditional wire spring:

1. In a very small installation space, a very high elastic output can be achieved.

2. Maintain a constant elasticity in all strokes.

3. The pre-stroke stroke is short, and only a short stroke is needed to achieve the required elasticity.

4. The original length is less than the wire spring, and the stroke is unlimited.

The manufacturing range of Dingli Clockwork:

The thickness is 0.05~0.85mm, and the width is 2.0~60mm.

Principle of the scene:

The constant force spring has the characteristic of maintaining a constant force during a long stroke, and can achieve extremely high elastic output in a very small device space. It can be applied to the nailing device of the nail gun to push linearly.

When the constant force spring is straightened by an external force, the spring will naturally retract and generate elastic force. It has sports functions such as balancing or saving effort. It can be applied to the height adjustment of computer monitors and electric fans.

The constant force spring can achieve extremely high elastic output in a very small device space. Its function can be applied to product applications that require linear motion such as reciprocating, sliding, stretching, returning, balancing or labor saving, such as automobile cup holders.

Constant force spring assembly method:

Double-layer spring/three-layer spring (the solution for narrow space use)

Straight-line series connection (the total output of pulling force is added)
