Mobile phone shrapnel TP 008

The shrapnel is a kind of elastic element widely used in the mechanical and electronic industries. When the shrapnel is loaded, it can generate large elastic deformation, transforming mechanical work or kinetic energy into deformation energy, and the deformation of the shrapnel disappears and returns to the original state after unloading. The deformation energy is converted into mechanical work or kinetic energy.

The shrapnel is complex and diverse, and is divided into shapes, including battery shrapnel, copper shrapnel, and stainless steel shrapnel. Shrapnel is generally used

1. Control the movement of the machine, such as the valve shrapnel in the internal combustion engine, the control shrapnel in the clutch, and so on.

2. Absorb vibration and impact energy, such as cushioning shrapnel under the car, train compartment, and shock absorbing shrapnel in the coupling.

3. Storage and output of energy as power, such as clock shrapnel, shrapnel in firearms, etc.

4. Used as a force measuring component, such as a force gauge, a shrapnel in a shrapnel scale, and the like.

The ratio of load to deformation of the shrapnel is called the stiffness of the shrapnel. The stiffer the stiffer the harder the shrapnel.

The elastic piece can be divided into a tension spring, a compression spring, a torsion spring and a bending spring according to the nature of the force; the shape can be divided into a disc spring, a ring spring, a leaf spring, a coil spring, a truncated cone scroll spring, and Torsion bar springs, etc. Ordinary cylindrical springs are widely used because they are simple to manufacture and can be made into various types according to the load conditions.

Spring manufacturing materials should generally have high elastic limit, fatigue limit, impact toughness and good heat treatment properties. Commonly used are carbon spring steel, alloy spring steel, stainless spring steel, and copper alloy, nickel alloy and rubber. Wait. Springs are manufactured by a cold roll method and a hot roll method. The general-purpose cold-roll method in which the spring wire diameter is less than 8 mm and the hot-roll method in which the spring wire diameter is larger than 8 mm. Some shrapnel are also subjected to strong pressure or shot peening after being manufactured, which can improve the bearing capacity and service life of the spring.

Most materials have varying degrees of elasticity, and if they are bent, they will return to their original shape with great strength. In human history, it has long been noted that the branches of saplings and saplings are very flexible, because many primitive cultures use this feature to wedge a stick behind a special door or cage, or with a slip knot. The sleeve is pulled down on a rod; once the tension is released, the stick or rod will rebound.

The ratio of load to deformation of the shrapnel is called the stiffness of the shrapnel. The stiffer the stiffer the harder the shrapnel. According to the nature of the force, the shrapnel can be divided into stretch shrapnel, compression shrapnel, torsion shrapnel and curved shrapnel. According to the shape, it can be divided into disc shrapnel, ring shrapnel, shrapnel, spiral shrapnel, truncated cone scroll and torsion shrapnel. . Ordinary cylindrical shrapnel is widely used because it is simple to manufacture and can be made into various types according to the loaded condition.

The manufacturing data of shrapnel should generally have high elastic limit, fatigue limit, impact toughness and good heat treatment performance. Commonly used are carbon shrapnel steel, alloy shrapnel steel, stainless shrapnel steel, and copper alloy, nickel alloy and rubber. Wait. The manufacturing method of the shrapnel is a cold roll method and a hot roll method. The general-purpose cold-roll method in which the shrapnel wire diameter is less than 8 mm and the hot-roll method in which the shrapnel diameter is larger than 8 mm. Some stainless steel shrapnel are also subjected to strong pressure or shot peening after being made, which can improve the load-bearing capacity of the shrapnel.
