What is a tension spring?

What is a tension spring? In fact, extension springs are springs that are commonly used in daily life. Extension springs are also called extension springs and extension springs. Extension springs are coil springs that accept axial tension. Extension springs are generally made of round cross-section materials. , When the load is not accepted, the coils of the tension spring are generally tight and there is no gap.

First, the characteristics of the extension spring

Extension springs, also known as spiral extension springs, are generally of equal pitch and mostly circular in cross section. They can be used in many occasions, such as production and assembly, testing, research and development, and maintenance. Tension springs occupy an important position in the global market and are widely used in national defense, marine, computers, electronics, cars, molds, medicine, biochemistry, aerospace, railways, nuclear power, wind power, thermal power, construction machinery, mining machinery, construction machinery, Elevator and other fields.

Second, the characteristics of the extension spring

Many different terminal devices may be used to ensure the origin of the tension of the tension spring. The working principle of the tension spring is opposite to that of the compression spring. The compression spring has a reverse effect when it is compressed, and the extension spring has a reverse effect when it expands or swings. When the ends of the tension spring swing apart, the spring will try to pull them back together. Like compression springs, extension springs also absorb and store energy. But unlike compression springs, most extension springs are usually under a certain degree of tension, even without any load. This initial tension determines how tightly the tension spring wraps around without any load. Craft spring

Three, the effect of the tension spring

The effect of extension springs, extension springs are mainly used for daily hardware accessories. The lamps, water heaters, electronic scales, sockets, etc. in the house all involve the use of extension springs. Tension springs also occupy a place in the electronic and electrical industry, such as vacuum cleaners, washing machines, televisions, cameras, etc. The accessories of the craft design also include the application of some tension springs such as toys, handbags, leather goods and other small crafts. Various machinery such as mining machinery and construction machinery are used in the industry and car fields. Although the tension of the spring is very small, the effect is quite large, which can reduce the shock of some instruments and protect the instruments. Extension springs do not have high requirements for the operating environment, so they can be used in a wide range of corrosion resistance, high and low temperature environments. Mechanical spring
