Dimensional relationship

 

 

 

 

 

(1) Spring wire diameter d: The diameter of the copper wire used to manufacture the spring wire;

 

 

 

(2) Spring coil diameter D: The outer diameter of the coil of the spring wire;

 

 

 

(3) Spring wire inner diameter D1: The inner diameter of the spring wire;

 

 

 

(4) Spring wire spiral length L: The static length of the spring wire under no external force;

 

 

 

(5) Spring wire working length L0: The dynamic length of the spring wire under external force sitting down;

 

 

 

(6) Spring wire unfolding length A: The total length of the straight line required to wind the spring wire;

 

 

 

(7) Spring wire tail length: The tail length at both ends is represented by L1 and L2, respectively;

 

 

 

(8) Spiral direction: There is a distinction between left and right rotation, commonly using right rotation. For areas not specified on the drawing, right rotation is generally used.

 

 

 

 

 

Comparison between Folding Mist Spring Wire and Bright Spring Wire

 

 

 

Mist surface spring wire, bright surface spring wire; Under normal circumstances, foggy spring wire is easier to form than glossy spring wire. And during the heat treatment process, the fog surface spring wire will not turn yellow, so the fog surface spring wire is more expensive than the bright surface spring wire!
