Spring we all know it, extension springs you understand? Extension springs are conceivably a kind of spring, extension springs in some care equipment, as well as some hand tools and computers and other industries will be used, that extension springs are so widely used, what are the advantages of extension springs?
Extension springs are generally equal-pitch, and most of the cross-section is round, extension springs are also not subject to pressure, each circle and each circle is no gap between the connection is very compact. Extension springs are used in a wide range of applications, in the medical field, not only respiratory equipment, mobile equipment applications, motion control, and some home care equipment are used, mechanical and electronic protective hardware, actuators, and hand tools, as well as some mechanical, switchgear are used to the extension spring.
Extension springs are very important to the world, the sea, national defense, as well as wind, railroads, aerospace and machinery, elevators and other fields, extension springs have an irreplaceable role.
What are the advantages of extension springs?
The working principle of extension springs is just the opposite of that of compression springs, which have a reverse effect when they are under pressure, while extension springs have a reverse effect when they are stretched. When the extension spring chants pull away, the spring tries to pull back, which creates force.
Extension springs can absorb and store energy, extension springs and compression springs, the difference is that the extension spring in a certain tension or no tension, this initial state determines the degree of tightness of the extension spring. In this way the initial force can be controlled to meet the needs of the inaccessible conditions.
The ends of the extension spring are fixed to other components at the time, and then when these components are separated, the extension spring comes into play, and the coils are tightened together to produce a strong tensile force, which connects the components together. These spring coils in the absence of tension tightly connected to the amount of spring closure including hooks hanging on the other components, as well as small holes and geometric interfaces, with these fixed in the need to connect the components will not be a problem, so that when there is tension will provide a certain amount of resilience for these components.
What are the common extension spring materials?
Extension springs often have the main material carbon spring steel, this is cheaper, but the elastic limit is low; low manganese spring steel, with good strength and hardenability, but quenching is prone to cracking; silicon-manganese spring steel, the elastic limit has improved, but also has good mechanical properties; chrome-vanadium steel, toughness and strength are better, the price is also slightly more expensive.
The above is for you to introduce a little bit of extension springs and often a few spring materials, you are not a certain understanding of it, I hope to help you.
