Spring material and allowable stress

Springs are often subjected to variable loads or impact loads during work. In order to ensure that the springs can work reliably for a long time, their materials must have high elastic limits and fatigue limits, and at the same time should have sufficient toughness and plasticity, as well as good heat treatment. For spring materials and properties, please refer to relevant manuals, specifications and standards (GB/T129.6-92, GB4357-89). Commonly used spring steel mainly includes:

What is the role of each element in the spring

We know that stainless steel hardware springs are more beautiful in appearance and corrosion-resistant than ordinary springs. However, there is no difference between stainless steel hardware springs and ordinary springs in terms of elastic properties. The main thing depends on the material composition of the spring. This also determines the price difference of stainless steel hardware springs.

Scroll spring processing technology

Everyone is familiar with springs. We usually use rectangular compression springs. This kind of spring is often used on ballpoint pens. Other types of springs may not be too common for everyone. Springs will be used in many products, such as presses and some bouncers, because the spring has a relatively good rebound ability and just meets the needs of these products. As mentioned above, there are many types of springs. What I want to introduce here is scroll springs. With the development of scroll springs in recent years, there have been many advancements in processing technology. Let me learn about them together.

The magical use of springs in these industries!

Let's take a look at the application of springs in these industries

How to avoid improper use of springs

1. Avoid applications that exceed the maximum compression. The pressure will cause breakage and close to long use. This will make the hardware spring wire gradually close, so the higher the fixed number of the hardware spring will cause the load curve to follow It will cause the spring to break at this time, so it cannot be used more than 300,000 times.
