The ratio of load and deformation of the shrapnel is called the stiffness of the shrapnel. The greater the stiffness, the harder the shrapnel. According to the nature of the force, the shrapnel can be divided into stretch shrapnel, compression shrapnel, torsion shrapnel and bending shrapnel, according to the shape can be divided into disc-shaped shrapnel, ring shrapnel, shrapnel, spiral shrapnel, truncated cone spiral shrapnel and torsion shrapnel . Ordinary cylindrical spring leaf because of simple manufacturing, and can be made according to the load situation of various types, simple structure, so the most widely used.
Shrapnel manufacturing materials in general should have a high elastic limit, fatigue limit, impact toughness and good heat treatment properties, commonly used carbon steel shrapnel, alloy steel shrapnel, stainless steel shrapnel and copper alloy, nickel alloy and rubber Wait. Shrapnel manufacturing methods are cold roll method and hot roll method. Shrapnel wire diameter less than 8 mm commonly used cold roll method, more than 8 mm with the hot roll method. Some shrapnel made even after the pressure or shot peening can improve the bearing capacity of the shrapnel. Shrapnel is widely used in the mechanical and electronic industries as an elastic element. The shrapnel can generate large elastic deformation when being loaded, and transform the mechanical work or kinetic energy into deformation energy. After the unloading, the deformation of the elastic sheet disappears and returns to its original shape. Deformation can be transformed into mechanical work or kinetic energy.
Shrapnel's main features:
① control the movement of machinery, such as valve shrapnel in the internal combustion engine, clutch control shrapnel and so on.
② absorption of vibration and impact energy, such as cars, train cars under the buffer shrapnel, coupling shock absorber shrapnel and so on.
③ storage and output of energy as a driving force, such as watch shrapnel, firearms and other shrapnel.
④ as a force measuring device, such as dynamometer, shrapnel in the shrapnel and so on.
