Conical Close And Ground Square End Compression Coil Spring
The characteristics of Compression spring is under axial pressure of the spiral spring, can withstand the pressure, both ends can be open or closed or round flat or smooth, materials used in the cross section is round more, it is also useful for rectangular and multi-strand steel rolled a travelling, springs have a pitch and defect, such as the shape of the compression spring are: cylindrical, conical, convex and concave, and a small amount of noncircular and the variation of various end, All products need to be shaped in accordance with the design, etc. There is a certain gap between the rings of the pressure spring and the rings. When subjected to external load, the spring contracts and deforms, and the deformation energy is stored.
Design parameters
Compression spring necessary information:
(1) Pressure spring control diameter (a) outer diameter, (b) inner diameter, installation guarantee size (C) the inner diameter of the casing, (d) the outer diameter of the round rod.
(2) Wire or bar size.
(3) Materials (type and grade).
(4) number of turns :(a) total number of turns and (b) right or left.
(5) Style of ends
(6) Load at a certain length of torsion zone.
(7) Load ratios ranging from one inch to several inches in length.
(8) Maximum solid height.
(9) Minimum compression height when used.
Please indicate on the drawing: material diameter (D), outer diameter (D), free height (Ho), total circle (N 1), number of working circles (n), pitch (t), screw direction: there are left and right rotation, usually right rotation, if not indicated on the drawing, usually right rotation. Load is required to be loaded (p 1 p 2...... P I) and corresponding values (H1H2...... Hj) or (F1F2... Fj:).
Design and production
1. Choose spring material according to the standard according to the actual product demand.
2. According to the product force value and compression stroke, fatigue and other requirements, determine the inner and outer diameter of the pressure spring, the effective number of turns, and the value range of the line diameter.
3. Substitute relevant parameters into the design parameter formula..
4. It is also reasonable and feasible to design and produce spring manufacturers.
