### Various parts of the CNC spring machine

- Mar 20, 2018 -

Various parts of the CNC spring machine are:

(1) The spring wire diameter of the CNC spring machine d: the wire diameter of the spring.

(2) Spring Outer Diameter D: The maximum outer diameter of the spring.

(3) Spring inner diameter D1: The minimum outer diameter of the spring.

(4) The diameter of the spring D2: the average diameter of the springs, their calculation formula

The name of each part in the numerical control spring machine is:

(1) The diameter of the spring wire of the numerically-controlled spring machine d: The wire diameter of the spring is manufactured.

(2) Spring Outer Diameter D: The maximum outer diameter of the spring.

(3) Spring inner diameter D1: The minimum outer diameter of the spring.

(4) Spring diameter D2: the average diameter of the springs, their calculation formula is: D2 = (D + D1) ÷ 2 = D1 + d = D-d

(5) t: In addition to the support ring, the axial distance between the corresponding points of the adjacent two rings of the spring on the middle diameter becomes the pitch, denoted by t.

(6) Number of effective springs of NC spring: n The number of turns of the spring can be kept at the same pitch.

(7) Number of support rings n2: In order to make the springs work evenly, ensure that the axis is perpendicular to the end face, when manufacturing, often the two ends of the spring are tight, and the number of tight turns only serves as the support, which is called the support ring. Generally 1.5T, 2T, 2.5T, 2T is commonly used.

(8) Total number of laps n1: The sum of the effective laps and the support ring. That is n1=n+n2.

(9) Freedom High H0: The height of the spring under no external force. Calculated from the equation: H0=nt+(n2-0.5)d=nt+1.5d (when n2=2)

(10) The spring deployment length L of the numerical control spring machine: the length of the required steel wire when winding the spring. L≈n1 (ЛD2)2+n2 (compression spring) L=ЛD2 n+ hook extension length (tension spring)

(11) Spiral direction: There is a left and a right rotation. The common right-handed rotation is used, and the drawing does not indicate the general use of right-handed rotation.
