What are the functions of spring shrapnel for metal stamping parts

Netizens asked: What are the functions of spring shrapnel for metal stamping parts? 　　 Expert reply: Because of its characteristics, spring plates are widely used in mechanical equipment manufacturing, electronics, electrical appliances, computers, high-tech product parts, etching, auto parts, kitchen supplies, Industry fields such as adjustment gaskets, stainless steel foil packaging molds, etc. What is the function of the spring shrapnel of the metal stamping parts? 　　(1) It can control the mechanical movement, such as the valve shrapnel in the internal combustion engine and the control shrapnel in the clutch.　　(2) It can store and output energy as power, such as shrapnel from clocks and firearms and so on.　　(3) It can absorb the energy of vibration and impact, such as the cushion shrapnel under the car and train carriage and the vibration-absorbing shrapnel in the coupling, etc.　　(4) It can be used as a component for measuring force, such as force measuring device and shrapnel in 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 compressed shrapnel and curved spring shrapnel, etc. If divided according to the shape, it can be divided into disc-shaped shrapnel, annular shrapnel, truncated scroll shrapnel, torsion bar shrapnel and so on.
