Whether in industrial manufacturing or daily work life, we can see that all kinds of springs are suitable for various places. There are many types of springs. Compression springs and tension springs are two common forms of spring products. These two forms of springs have certain similarities in appearance and function, but in essence, these two springs have certain differences. Below spring contact manufacturers share what is the difference between compression spring and tension spring.

1. Tensile spring

A tension spring is a coil spring that is subjected to axial tension, and a circular cross-section material is usually used to make the production stock. When gravity is not loaded, the circle and the circle of the extension spring are usually very hard and there is no gap.

2. Compression spring

The compression spring is a compressed coil spring, and the material used is mostly circular in cross-section. However, rectangular and multi-strand steel are wound together, the spring is usually of equal pitch, and the shape of the compression spring is usually composed of cylindrical, conical, middle convex, middle concave, a small amount of non-circular, etc. There is usually a certain interval between the circle and the circle of the compression spring.

What parameters will affect the spring force?

(1) Within the elastic limit, the elasticity of the spring is proportional to the deformation (tension or compression value) of the spring. Write: f = k x

(2) The "f" in the expression represents the spring force, that is, the force exerted on the object when the spring is deformed.

(3) "x" is the length of the spring extension or shortening. "X" is based on the length of the spring when it is not visible (that is, X = X'-x0 or X = x0-X).

(4) "k" is the stiffness coefficient of the spring, which is used to explain the elasticity caused by unit deformation. The greater the value of k, the greater the force required to deform a unit length, or the spring becomes "stiff". k is related to spring material, length and thickness. The international unit of k is N/m.

spring contact manufacturers share cleaning spring:

1. Take a proper amount of clean water and mix and dilute according to the ratio of cleaning agent A and clean water 1:1 or 1:2. The diluted solution is prepared in a plastic container. The stainless steel spring to be cleaned cannot be soaked in the container for too long. There is no oil on the surface of the spring. After restoring the original metal color, take it out and rinse with clean water, the surface can achieve the actual effect of matt.

2. Take some rough abrasives, put in the cleaning agent, and then put in the hexagonal roller. The volume ratio of spring and rough abrasive is 1:3, and the amount of cleaning agent is 1%-2% of the weight of the spring. The spring contact manufacturer believes that if the spring contact is fully ground and cleaned with clean water, the scratch on the surface of the spring will not exist.

Spring contact manufacturers talk about cleaning spring precautions:

Remove dust and its easy dirt, wash with soap, weak detergent or warm water, wipe labels and stickers with warm water, weak detergent, wipe fat, oil, lubricating oil pollution with a soft cloth or paper, use neutral detergent, ammonia solution or special detergent.
