How are the parts produced using the stamping process?

Stamping is a forming and processing method that relies on presses and dies to apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, so as to obtain workpieces (stamping parts) of the desired shape and size.

The car body, chassis, fuel tank, radiator fins, boiler drum, container shell, motor, electric appliance iron core silicon steel sheet, etc. are all stamped and processed. There are also a large number of stamping parts in products such as instruments, household appliances, bicycles, office machinery, and living utensils.

How are the parts produced using the stamping process?

is divided into hot stamping and cold stamping according to the stamping processing temperature. The former is suitable for sheet metal processing with high deformation resistance and poor plasticity; the latter is carried out at room temperature and is a commonly used stamping method for thin plates.

Sheets, molds and equipment are the three elements of stamping processing.

Sheet: The surface and internal properties of the sheet used for stamping have a great influence on the quality of the stamped product.

6 requirements for stamping materials

  • ① The thickness is accurate and uniform.
  • ② The surface is smooth, no spots, no scars, no scratches, no surface cracks, etc. Prevent the generation of waste products.
  • ③ The yield strength is uniform without obvious directionality. In order to reduce the occurrence of defective products or waste products
  • ④ High uniform elongation. To prevent uneven deformation.
  • ⑤ The yield ratio is low. In order to improve the accuracy of bending parts.
  • ⑥ Low work hardenability. In order to prevent future deformation

Mould: The precision and structure of the mould directly affect the forming and precision of the stamping parts. Mold manufacturing cost and life are important factors that affect the cost and quality of stamping parts.

How are the parts produced using the stamping process?
