Analysis of Plastic Deformation of Metal Materials by Precision Stamping Parts

Lithium battery small aluminum nails are a common type of precision hardware in Metal Stamping parts. These lithium battery small aluminum nails are formed through precision stamping processing, which includes different processing techniques such as ordinary stamping and precision stamping. Stamping refers to the processing of metal materials through a mold cavity under the punching of a punch, causing plastic deformation and forming the size and shape of the metal material.

The analysis of plastic deformation of metal materials is as follows: 1. Slip: the more slip systems there are, the better the plasticity; 2. The slip surface is affected by temperature, composition, and deformation; 3. The slip direction is relatively stable. 4. Twinning: fcc, bcc, hcp can all undergo plastic deformation as twinning; Generally occurs under low temperature and high speed conditions; Small deformation, adjust the direction of the sliding surface. 5. Yield phenomenon: Annealing, normalizing, and tempering are common in medium and low carbon steel and low alloy steel, which can be divided into discontinuous yield and continuous yield; Yield point: The stress value corresponding to the tensile yield of a material, σ s.

The above is an analysis of the plastic deformation of the metal material of precision stamped parts such as lithium battery small aluminum nails. In addition to the incomplete introduction of the above points and related theories, they will not be introduced one by one. The small aluminum nails of lithium batteries ultimately form a qualified precision hardware component, which requires better stamping knowledge and the characteristics of various raw materials, as well as professional technology to produce more stable and qualified precision stamping components.
