Effect of Mechanical Properties of Metal Materials on Stamping Performance

Aug. 30, 2019

The stamping properties of metal materials refer to the adaptability of metal materials to various stamping processes. The mechanical properties of metallic materials are the main determinants of the stamping properties of metallic materials. As an Aluminum Stamping Lids Supplier, let us explain to you.

1) Effect of elasticity on stamping performance

Separation processes such as blanking, punching, trimming, and trimming are more suitable for metal materials with better elasticity. Because of the separation of metal materials with good elasticity, the good quality cross-section can be obtained. Metal materials, due to their elasticity, will rebound after bending, so that the curved parts do not meet the predetermined shape and size requirements. And the better the elasticity, the bigger the rebound. The rebound of the bent parts caused difficulties in production and it took a lot of man-hours to repair the working part of Stamping Mould.

2) Effect of plasticity on stamping performance

Deformation processes such as bending, drawing, and forming are all based on the plasticity of the metal material. Metal material with good plasticity allows a large degree of deformation, and the number of process steps and the number of intermediate annealings can be reduced in the stamping, and even the intermediate annealing is not required as one of the indexes of the plastic deformation ability of the metal material. The uniform elongation of the metal material directly determines the stamping properties of the material. In practice, such as the degree of extreme deformation of press forming, such as the flanging coefficient, the necking coefficient, the minimum bending radius, the bulging coefficient, etc., can be expressed directly or indirectly by the uniform elongation. The separation process requires that the material has appropriate plasticity, too high plasticity, too soft material, large burrs for punching, and the size is not easy to meet the requirements. The plasticity is too low, the material is too hard and brittle, and the mold is easy to wear.

(3) Influence of strength and hardness on stamping performance

Metal materials have high strength and high hardness. The material has high strength and hardness, and its plasticity must be low. Therefore, a metal material having high hardness is disadvantageous for a deformation process such as bending, drawing, and molding. In general, the hardness of the material used in the deformation process is low, but the metal material having a certain strength and hardness can obtain good cross-sectional quality in the separation process.
