With the improvement of the quality of life,Automotive hardware stamping partshas penetrated into all areas. Whether in industrial production or daily life, there are many places where various metal stamping parts are used, which are closely related to our lives. What technological requirements do hardware processing plants need to produce automotive hardware stamping parts in order to produce hardware products that can meet the needs of consumers' production and life?
Process Requirements for Automotive Hardware Stamping Parts
1. The materials used in automotive hardware stamping parts must not only meet the technical requirements of product design, but also meet the requirements of stamping process and post-stamping processing.
2. When designing the structural shape of automotive hardware stamping parts, use simple and reasonable curved surfaces and their combinations, and at the same time reduce the number of processed surfaces and processed area as much as possible.
3. Choose a reasonable blank making method in mechanical manufacturing, which can directly use profiles, casting, forging, stamping and welding. The choice of blanks is related to the specific production technical conditions and generally depends on the production batch, material properties and processing possibilities. 4, metal stamping formability requirements. For the forming process, in order to facilitate stamping deformation and improve product quality, the material should have good plasticity, smaller yield ratio, larger plate thickness directivity coefficient, smaller plate plane directivity coefficient and smaller yield strength and elastic modulus ratio.
5. Specify the appropriate manufacturing accuracy and processing cost of parts with surface roughness. The processing cost of metal stamping parts will increase with the improvement of precision, especially in the case of high precision. Therefore, in the absence of sufficient basis, high precision should not be pursued. The surface roughness of the same automotive metal stamping parts should be appropriately specified according to the actual needs of the mating surface. The processing technology of automobile metal stamping parts is complex. In order to ensure the performance of metal stamping parts can meet the requirements of use, it is necessary to follow the corresponding process requirements to ensure the feasibility of production.
Technical Requirements for Automotive Hardware Stamping Parts
1, through chemical analysis and gold phase test analysis of the content of chemical elements in the material, to determine the material's grain size grade and uniformity, evaluation of the material in the level of free carburizing, ribbon tissue and non-metallic inclusions, check the material's shrinkage, loose and other defects.
2, material inspection stamping parts processing materials are mainly hot-rolled or cold-rolled sheet metal strip. The raw materials of metal stamping parts should have quality certificates to ensure that the materials meet the specified technical requirements. Metal stamping parts manufacturers can select raw materials for re-inspection according to their needs, when there is no quality certificate or other reasons.
3. Formability test: Bending test and cupping test were performed on the material, and the work hardening exponent N and plastic strain ratio R of the material were measured. The method for testing the formability of the steel sheet can be performed in accordance with the provisions of the steel sheet testing method and the formability.
Automotive metal stamping parts are thin, uniform, light and strong. Zhuhai Sanyuan Hardware Products specializes in the production of various metal stamping parts, using precision mold processing, focusing on the research and development and manufacturing of metal stamping parts, so that the precision of metal stamping parts Reach micron level.
