Because of its characteristics, spring pieces are widely used in mechanical equipment manufacturing, electronics, electrical appliances, computers, high-tech product parts, etching, auto parts, kitchen supplies, adjusting gaskets, stainless steel foil and other industries. What are the functions of metal stamping parts and spring shrapnel?
(1) It can control the mechanical movement, such as the valve spring in the internal combustion engine and the control spring in the clutch.
(2) It can store and output energy as power, such as the shrapnel of clocks and watches and the shrapnel of firearms.
(3) It can absorb the energy of vibration and impact, such as the cushion elastic pieces under cars and train cars and the vibration absorbing elastic pieces in couplings.
(4) It can be used as a force measuring element, such as the force measuring device and the shrapnel in the shrapnel scale.
The ratio of load and deformation of shrapnel is called the stiffness of shrapnel. The greater the stiffness, the harder the shrapnel. According to the nature of the force, the shrapnel can be divided into compression shrapnel and bending spring shrapnel, etc.; according to the shape, it can be divided into dish shrapnel, annular shrapnel, truncated cone scroll shrapnel and torsion bar shrapnel, etc.
