Precision Tension Spring Manufacturer
Tension Springs are familiar to many people and are widely used in life. Springs include tension springs and compression springs. In this article, we need to explain the characteristics of tension springs, which are often used in hand tools, shock absorption equipment, switch equipment machines, control valves and other tools. They are useful in various fields, and have various materials. Here, I will explain the characteristics of the tension spring and how to detect its characteristics to help you understand the tension spring.
The tension spring is a spiral spring that bears axial tension. It uses the tension after stretching to store energy. It will try to pull back to the original position after pulling away, and generate resistance. When not bearing load, the coils of the tension spring are tight, so the tightness of the coil of the tension spring is determined by the initial tension. Its production materials usually include stainless steel, piano steel, high carbon steel, phosphor copper, oil tempered alloy spring steel, etc.
The closure of the extension spring usually includes thread embedded, cross center pull ring, pull hook, enlarged small hole, reduced small hole, rectangular closure and water drop-shaped closure. The length from the closure to the spring body can be determined according to the specific situation. The more common is the hook tension spring, whose “hook” is the source of tension, and its shape is usually circular section, which is convenient to fix to the connected components.
