Next, let's talk about the correct design steps for tension springs.
Let's take a look at the correct design steps for tension springs together.
What is a tension spring? In fact, tension springs are a type of spring that we often use in our daily lives. Tension springs, also known as extension springs, are a type of helical spring that accepts axial tensile forces. They are generally made from materials with a circular cross-section, and when not under load, there is no gap or tightness between the coils of the spring.
There are two basic designs of tension springs: pre-tensioned springs and springs without internal pre-tension. The correct design steps for tension springs are as follows: 1. Pre-tensioned cold-bent springs are suitable for prestressing processing, so the working coils are closed. Preloaded springs can increase the load-bearing capacity of the spring. For specified lengths of spring deformation, high loads without preloading should be used. Pre-compression occurs during the winding process of the spring coils, and the dimensions depend on the materials used, spring index, and winding method. 2. If there is no internal pre-tension spring and it is not needed for technical reasons, loose-wound springs can be used without pre-tension. There will be gaps between the working coils. The task of spring design is to determine the geometric dimensions of the spring wire, such as diameter D and number of working coils N, to meet strength constraints, stiffness constraints, and stability constraints. The progress also requires corresponding design indicators (such as volume, weight, vibration stability, etc.) to achieve better results. The correct design steps for tension springs are as follows: Based on working conditions and requirements, try to choose materials for tension springs. The spring index is usually assumed in advance, and then calculate the diameter d of the spring wire, followed by calculating the values of d and n along with other corresponding geometric dimensions. If the results do not meet design conditions, the above process should be repeated.
Many different terminal devices can be 'hooks' to ensure the starting tension of the tension spring. The working principle of elastic springs is opposite to that of compression springs; when a stretched spring is compressed, it acts in an opposite manner. When a tension spring opens or expands, it acts in an opposite manner as well. When both ends of a tension spring expand, the spring will try to pull them back together. Like compression springs, elastic springs absorb and store energy; however, unlike extension springs, most extension springs typically operate under a certain amount of tension even without any load. This initial tension determines how tight or loose the elastic spring is when there is no load.
The above is what I explained about 'the correct design steps for tension springs.' I believe everyone has gained some understanding.
