The characteristics of the spring
12-30 / 2019
The characteristics of the spring leaf: 1. It can absorb the energy of vibration and impact, such as the buffer shrapnel under the car and train carriage and the vibration-absorbing shrapnel in the coupling. 2. It can store and output energy as power, such as watch shrapnel and Shrapnel in firearms. 3. It can control mechanical movement, such as valve shrapnel in internal combustion engine and control shrapnel in clutch. 4. It can be used as a force measuring component, such as force measuring device and shrapnel in shrapnel scale. 5 , Good sound insulation, excellent fire resistance, light weight and high strength, strong nail-holding power, good flatness, low moisture content, small expansion ratio, good durability, strong workability, easy to cut and easy to seam, and the surface of the seam is smooth , Not easy to crack. Generally speaking, the manufacturing materials of springs should have high elastic limit, fatigue limit, impact toughness and good heat treatment performance. Commonly used are carbon shrapnel steel, alloy shrapnel steel, stainless steel shrapnel, copper alloy, nickel alloy and rubber, etc. . Shrapnel manufacturing methods include cold rolling and hot rolling. Shrapnel yarns with a diameter of less than 8 mm generally use the cold rolling method, and those with a diameter greater than 8 mm use 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 capacity of the shrapnel. Spring leaf is a kind of elastic element widely used in machinery and electronic industries. Stainless steel shrapnel can produce large elastic deformation when loaded, converting mechanical work or kinetic energy into deformation energy, and after unloading, the deformation of the shrapnel disappears and returns to its original state. , Transforming deformation energy into mechanical work or kinetic energy.
