What are the main functions of shrapnel
12-02 / 2019

Everyone knows about shrapnel, so what exactly does it do?


1. Control the movement of machinery, such as valve springs in internal combustion engines, control shrapnels in clutches, etc.

2. Absorb vibration and impact energy, such as the buffer shrapnel under the car and train carriage, the vibration-absorbing shrapnel in the coupling, etc.

3. Store and output energy as power, such as shrapnel from watches and firearms.

4. Used as a force measuring element, such as a force measuring device, shrapnel in a shrapnel scale, etc. The ratio of the load to the 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, shrink shrapnel, torsion shrapnel and zigzag shrapnel. According to the shape, it can be divided into disc-shaped shrapnel, ring shrapnel, plate shrapnel, spiral shrapnel, truncated cone scroll shrapnel and torsion bar shrapnel, etc. . Ordinary cylinder

   shrapnel is the most widely used due to its simple production, and can be made into various types according to the load conditions, and its structure is simple.

Generally speaking, the production materials of shrapnel should have high elastic limit, fatigue limit, impact toughness and good heat treatment function, etc. Commonly used are carbon shrapnel steel, alloy shrapnel steel, stainless shrapnel steel, copper alloy, nickel alloy and rubber Wait. There are cold rolling and hot rolling methods for shrapnel. Shrapnel wire diameter less than 8 mm generally uses the cold rolling method, and larger than 8 mm uses the hot rolling method. Some shrapnels need to be subjected to strong pressure or shot peening after they are made to improve the load-bearing ability of the shrapnel. Shrapnel is a kind of elastic element widely used in machinery and electronic industries. Shrapnel can produce greater elastic deformation when loaded, and convert mechanical work or kinetic energy into deformation energy. After unloading, the deformation of the shrapnel disappears and returns to its original shape. Deformation energy is converted into mechanical work or kinetic energy.

  Most data have varying degrees of flexibility. If you twist them, they will restore their original shape with great effort. In human history, we must have noticed that the branches of saplings and saplings are very flexible. Because many primitive civilizations use this feature, a stick is wedge behind a special door or cage, or a slipknot is used to wrap it. A rod is pulled up and down; once the tension is released, the stick or rod will rebound. Use this method to catch birds and beasts. In fact, the bow uses the elastic shrapnel of the young tree in this way; first pull the bow back, then let go to let it rebound. In the Middle Ages, this idea began to appear in machinery, such as textile machines, lathes, drilling machines, surface grinding machines, and saws.
