What is the difference between stainless steel compression spring and extension springs?

 In our lives, many things use springs. Springs have become necessities for many things. These things are produced in different industries. Therefore, since objects cannot be separated from springs, industry cannot be separated from springs. . Springs are a kind of messy appearance, large and small, thick and thin, and some surfaces also have colors. In short, they are characterized by good elasticity, and some have different characteristics and use. The following Zhejiang spring manufacturer introduces the difference between compression spring and extension spring.

First of all, from a design perspective, there are many differences between the two in design

(1) The basic parameters required for compression spring design are outer diameter, inner diameter and length, which are also the space occupied by the spring. This is the first condition. Spring force, when the spring is in the working state, it is necessary to clearly understand the actual force (N) required in order to select the material, wire diameter and compression, that is, the compression stroke, so as to determine the number of turns.

(2) Spring working environment, working in a high humidity environment, the surface of the spring should be treated to prevent corrosion and moisture; working in a high temperature environment, because temperature has a great influence on the service life of the spring, so high temperature environment work needs to be selected High temperature R. Electrostatic material, working normally.

Second, the key elements of Extension spring design

(1) The required tension, that is, the weight that can be loaded, determines the material, wire diameter and adjustable length of the Extension spring. Space range, knowing the space range, you can determine the outer diameter, free length and winding times of the Extension spring.

Finally, in terms of shape

(1) For Extension spring, Extension spring is a coil spring under axial tension. For Extension spring, it is usually made of circular cross-section material. In the case of no load gravity, the tension between the coil springs is usually very tight, and there is no gap between the rings.

(2) For the compression spring, the compression spring is used under the pressure of the coil spring, and the material used in it is mostly circular in cross section. It is also useful to have a stroke made of rectangular and multi-strand steel. The spring is usually It is for the pitch. For example, the shape of the compression spring is: cylindrical, conical, convex and concave, and a small non-circle. When the amount is large, the compression spring has a certain gap between the circle and the circle. When the spring shrinks and deforms under the action of external load , Deformation energy storage.
