Precision stamping manufacturing process has become an important part in the parts industry. Most stamping hardware is used in aerospace, automobile, ship, machinery, chemical industry and other fields. How does the precision stamping manufacturing process produce and process? The precision stamping process has high production efficiency, convenient operation, and is easy to realize mechanization and automation. As for the precision stamping manufacturing process as a whole, the precision stamping process is mainly affected by two factors: equipment type and workpiece material.
1、 Technological Advantages of Precision Stamping
Precision stamping parts are manufactured by stamping on the premise of low material consumption, and the parts produced are light in weight and good in stiffness. It also has high scale accuracy, uniform and common scale with the module, and good interchangeability. During the stamping process, because the appearance of the material is not easy to be damaged, it can retain good appearance quality, and the appearance is lubricated and beautiful, which provides convenient conditions for subsequent surface treatment.
2、 Material Selection for Precision Stamping
There are three main stamping processes: blanking, bending and stretching. Different processes have different requirements for plates. The selection of materials should also be based on the general shape of the product and processing technology.
1. Blanking requires that the sheet should have enough plasticity to ensure that the sheet will not crack during blanking. Soft materials have good blanking performance, so that parts with smooth section and small inclination can be obtained after blanking
2. The plates to be bent shall have sufficient plasticity and low yield limit. The plate with high plasticity is not easy to crack when bending. The plate with low yield limit and low elastic modulus has small rebound deformation after bending, and it is easy to obtain accurate bending shape. The material with greater brittleness must have a larger relative bending radius when bending, otherwise it is easy to crack during bending.
3. Deep drawing is one of the most difficult processes in precision stamping. Therefore, it is not only required that the drawing depth should be as small as possible, the shape should be as simple and smooth as possible, but also that the material should have good plasticity. Otherwise, it is easy to cause the overall distortion, local wrinkling, and even tension cracking of parts.
