    Spring is a kind of elastic element widely used in the mechanical and electronic industries. Spring can produce greater elastic deformation when loaded, and convert mechanical work or kinetic energy into deformation energy. After unloading, the deformation of spring disappears and returns to its original state, and the deformation energy is transformed into mechanical work or kinetic energy.The ratio of load and deformation of the spring is called spring stiffness.  There are many kinds of springs. They are used in various fields. According to the deformation condition, they can be divided into three kinds: spring, spring and spring.Compression spring compression spring (springs) is under axial pressure of the spiral spring, it is used in the data section for more rounded, useful...

    Compression springs are frequently seen and used in daily life. The main principle of compression springs is to provide a hand to the machine and drive it to work.The compression spring has a certain damping capacity, because the product's elastic force is not a fixed value, so every time it is used, there will be a return force, and the force is not a fixed size, which to some extent has the ability to slow down the vibration.As an example, now the car is installed above a compression spring, you will find when driving, its speed is greatly improved, and the movement process there is no sound, you don't need to use a lot of power, can make the speed of the car, this is the charm of compression spring, because it's there, so now in the car production technology is more and more...

    The corrosion of spring can be divided into chemical corrosion and electrochemical corrosion according to the type of reaction.They are the result of changes in the metal atoms on the surface of the spring or the loss of electrons to an ionic state.If the metal on the surface of the spring simply reacts with the surrounding medium, and the spring causes corrosion, it is called chemical corrosion.For example, the spring is oxidized in the particularly dry atmosphere to form an oxidation film, and the spring is chemically changed with the liquid or impurity in the non-electrolyte liquid, which is a chemical corrosion.If the spring is in contact with the electrolyte solution, the corrosion caused by the action of the micro battery is called electrochemical corrosion.For example, the spring is...

Springs are ubiquitous in all kinds of machines—from consumer products to heavy industrial equipment, take apart anything that involves a mechanism, and chances are, you’ll find a spring inside. Springs are storage devices for mechanical energy—think of them as analogous to batteries! The earliest spring-driven clocks appeared in the 1400s. Fast-forward some 600 years, you still have to charge the Apple Watch everyday, and it’s not nearly as fast as winding a clock…but I digress.My personal fascination with springs began with Slinkies and wind-up toys, and countless mechanical pencils were sac...

The spring is often subjected to variable load or impact load. In order to ensure that the spring can work permanently and reliably, the material must have high elastic limit and fatigue limit. At the same time, it should have enough toughness and plasticity and good heat treatment.Spring materials and properties can be consulted in relevant manuals, specifications and standards (GB/T129.6-92, GB4357-89). The common spring steel is mainly:1: carbon spring steelThis kind of spring (such as 65, 70 steel, etc.) has the advantages of cheap price, convenient source of raw materials, low elastic limit, easy to lose elasticity after repeated deformation, and can not work at 130 degrees.2: low manganese spring steelCompared with carbon spring steel, the spring steel, such as 65Mn, has the advantag...

Like most other basic mechanisms, metal springs have existed for a long time in the bronze age. Even for metals, wood is used as a structural member of flexible bow and arrow and military catapult. In the Renaissance, precise clocks made precision springs the first necessity. In Fourteenth Century, we saw the precise clock of revolutionary astronomical navigation developed. The world's exploration and conquest of European colonial powers continue to provide impetus for watchmakers "science and art." The other area of the firearm promotes the development of the spring. At the dawn of the industrial revolution in eighteenth Century, a large, accurate and cheap spring was proposed. Whereas the watchmaker's spring is often made by hand, the spring mass production is made of p...

Torsional springs are a kind of helical springs, which mainly produce torque or rotational force. The end of the torsion spring is fixed to other components. When other components rotate around the center of the spring, the spring pullback them back to the initial position. Although this spring is called torsion spring, it is subject to bending stress rather than torsional stress. The torsion spring can store and release angular energy or fix a device in a static way by rotating the force arm around the middle axis of the spring body. Torsion springs are usually tight, but there is pitch between spring rings to reduce friction. They produce resistance to rotating or rotating external forces. According to the application requirements, the rotation direction (clockwise or counterclockwise) o...

Springs can also be classified by how they’re made. The first spring that comes to most people’s minds is probably a metal coil spring, also known as a helical spring. However, there are many other types. Even an elastic band can be considered a variable rate spring, since it stores mechanical energy.Coil SpringsLightweight coil springs are made by forming metal wires on an CNC coiling machine. The multi-axis CNC control allows you to create variable pitches and end conditions only limited by your imagination. Springs that come off the coiling machines do not have springy properties. They need to be heated to a high temperature (typically 500 degrees Fahrenheit or more) to relieve stress, then quenched to create shape memory.In contrast, when making heavy duty coil springs, the wire is hea...

We can look at the relationship between the force applied to a spring and its resulting displacement. Again, there are three classes of springs: linear (or constant rate) springs, variable rate springs, and constant force springs.Linear springsLinear springs obey Hooke’s Law (F=k*x), which means that the force needed to extend or compress such a spring by distance x is proportional to the distance, as long as the force doesn’t exceed the elastic limit of the spring. Torsion springs obey an analogous version of Hooke’s Law (F=k*θ, where θ is an angle). In both cases, k is the spring rate, and it stays constant, no matter the spring’s deflection. This is why linear springs are also known as constant rate springs.Variable rate springsOn the other hand, a variable rate spring doesn’t have the ...
