Classification of hardware shrapnel

The hardware spring is a mechanical part that uses elasticity to work. Generally made of metal shrapnel steel. It is used to control the movement of parts, alleviate impact or vibration, store energy, measure the size of force, etc. It is widely used in machines and meters. The types of hardware shrapnel are complex and diverse. According to the shape, there are mainly spiral hardware shrapnel, scroll hardware shrapnel, and plate hardware shrapnel.　　Hardware shrapnel belongs to the category of metal stamping parts and electronic hardware materials. It is made of stainless steel or manganese after heat treatment. It is an important part of the switch. With the help of the conductivity of the metal shrapnel, it acts as a high-quality switch between the operator and the product. At the same time, using the stable resilience of the guozi (automatically return after pressing), and the long life, provide the operator with high-quality tactile feedback.　　Stainless steel or metal manganese material is made of heat-treated shrapnel, which has a long life. It can also be gold-plated, chrome-plated or silver-plated depending on the occasion of use. Do surface treatment.　　 Main materials: 301, 304, 430, 409L, 410, 316L, and other stainless steel materials with complete varieties and reasonable prices. The surface has: 2B, BA, frosted, oiled wire drawing, 8K mirror panel, and film. Specification range: Thickness 0.01mm—3.0mm * Width 3 mm—　　 Material hardness: Vickers (HV) 180—more than 550 Hardness status: ANN, 1/4H, 1/2H, 3/4H, H, EH, 　　 shrapnel is The only metal component in the membrane switch is widely used. In the current situation, the use of shrapnel in many products is confusing, especially in flexible circuits, where it is only used as a component that provides hand feeling (tactile feedback), so that the performance of the membrane switch has many disadvantages, and even the membrane switch loses its due The role of. Hardware shrapnel is a kind of elastic element widely used in machinery and electronic industries. The hardware shrapnel can produce large elastic deformation when loaded, and convert mechanical work or kinetic energy into deformation energy. After unloading, the deformation of the hardware shrapnel disappears and recovers. In its original state, transforming deformation energy into mechanical work or kinetic energy.
