What Are The Stamping Performance Requirements For Metal Materials?

Stamping performance requirements for metal materials

(1) Has good mechanical properties and large deformation resistance

The mechanical properties of metallic materials refer to tensile strength, yield strength, elongation, hardness, plasticity, strain ratio, and the like.

(2) has an ideal metallographic structure

Metallographic structure is the microscopic quality characteristic of the material. Its main sign is: the degree of spheroidization of cementite or carbide.

The requirements for stamping materials are:

1 thickness is accurate and uniform. The stamping die is precise, the gap is small, the thickness of the sheet is too large to increase the deformation force, and the jam is caused, and even the die is cracked; if the sheet is too thin, the quality of the finished product is affected, and even the crack occurs even when the drawing is deep.

2 The surface is smooth, no spots, no flaws, no scratches, no surface cracks, etc. All surface defects will remain on the surface of the finished workpiece, and the crack defects may be deepened and expanded in the process of bending, deep drawing, forming, etc., resulting in waste.
