What are the characteristics of stamping parts

Stamping parts are mainly formed by stamping metal or non-metallic sheets with the help of the pressure of the press and through the stamping die. They mainly have the following characteristics:
⑴ Stamping parts are manufactured by stamping under the premise of small material consumption. The parts are light in weight and have good stiffness. After plastic deformation of the sheet metal, the internal structure of the metal is improved, so that the strength of the stamping parts is improved.
⑵ Stamping parts shall have high dimensional accuracy, uniform and consistent dimensions with the module, and have good interchangeability. General assembly and use requirements can be met without further machining.
(3) During the stamping process, the surface of the stamping parts will not be damaged, so they have good surface quality, smooth and beautiful appearance, which provides convenient conditions for surface painting, electroplating, phosphating and other surface treatment.
Flange stamping
⑴ The designed stamping parts must meet the product use and technical performance, and be easy to assemble and repair.
⑵ The designed stamping parts must be conducive to improving the utilization rate of metal materials, reducing the varieties and specifications of materials, and reducing the consumption of materials as much as possible. If allowed, materials with low price shall be used to make the parts blanking without waste and with less waste as far as possible.
(3) The designed stamping parts must be simple in shape and reasonable in structure, which is conducive to simplifying the mold structure and the number of processes. That is, the minimum and simplest stamping process is used to complete the processing of the whole part, and the use of other methods is reduced. It is also conducive to stamping operations, so as to facilitate the organization of mechanized and automated production and improve labor productivity.
(4) Under the condition that the designed stamping parts can be used normally, the requirements for dimension accuracy grade and surface roughness grade should be as low as possible, which is conducive to product interchange, reducing waste products and ensuring stable product quality.
⑸ The designed stamping parts shall be conducive to the use of existing equipment, process equipment and process flow to process them as much as possible, and to the extension of the service life of the stamping die.
