Definition of hardware shrapnel
   metal shrapnel is a kind of elastic element widely used in mechanical and electronic industry. When loaded, metal shrapnel can produce large elastic deformation, which converts mechanical work or kinetic energy into deformation energy. After unloading, the deformation of metal shrapnel disappears and returns to its original state, which converts deformation energy into mechanical work or kinetic energy.
Production technology of metal shrapnel
    metal shrapnel production is a special process to process materials (metal or non-metal) into parts (or semi-finished products) through cold stamping of stamping dies. Stamping is a kind of pressure processing method which uses the die installed on the press to exert pressure on the material at room temperature to produce separation or plastic deformation, so as to obtain the required parts.
Application field of metal shrapnel
   1. Storage and output of energy as power, such as clock hardware shrapnel, mechanical hardware shrapnel, etc.
   2. Control the movement of machinery, such as valve hardware spring in internal combustion engine, control hardware spring in clutch, etc.
   3. Absorb vibration and impact energy, such as buffer metal shrapnel under car and train carriage, vibration absorbing metal shrapnel in coupling, etc.
   4. It is used as force measuring element, such as force measuring device, metal shrapnel in metal shrapnel scale, etc. The greater the stiffness of the hardware, the greater the stiffness of the shrapnel.
