The characteristics design and material advantages of automobile stamping parts: compared with castings and forgings, stamping parts have the characteristics of thin, even, light and strong. Stamping can make workpiece with reinforcement, rib, rolling or flanging to improve its rigidity. Other methods of these artifacts are difficult to produce. Because the stamping parts adopt precision die, the precision of the workpiece can reach micron level, and the repeated precision is high and the specification is consistent, so the hole socket and boss can be punched out, so the more and more widely used the stamping parts are.
In the design of metal stamping parts, not only the structure of the stamping parts should meet the requirements of use, but also the requirements of the structure and technology of the metal stamping parts must be considered, that is, the structure of the metal stamping parts should be suitable for the stamping process. The metal stamping parts with good structure and technology can reduce or avoid the production of stamping defects, and can easily ensure the quality of stamping parts, and also simplify stamping process, improve productivity and reduce production cost. The main factors affecting the technological performance of metal stamping parts are the shape, size, accuracy and materials of the metal stamping parts.
Stamping parts are parts that can be processed by stamping, bending, stretching and other means. Metal stamping parts are widely used in all fields of our life, including some electronic devices, automobile accessories, decorative materials, etc.
The structural and technological properties of metal stamping parts are as follows:
1. Stamping parts are made by stamping under the premise of small material consumption. The parts are light weight and good rigidity. After the sheet metal is plastic deformation, the structure of the metal interior is improved, and the strength of the stamping parts is improved.
2. Stamping parts have high dimensional accuracy, uniform size with the die, and have good interchangeability. No further machining is required to meet the general assembly and use requirements.
3. In stamping process, the surface of the material is not damaged, so it has good surface quality and smooth appearance. This provides convenient conditions for surface painting, electroplating, phosphating and other surface treatment.
