Metal stamping parts
Stamping the sheet surface and intrinsic properties on stamping a great influence on the quality of the finished product, need accurate, uniform thickness stamping materials surface, smooth, no spots, no scars, no bruises, no cracks on the surface; the yield strength even without obvious direction; high uniform elongation rate; low yield ratio; work-hardening low.
In practice, common and stamping process similar to the process of testing, such as deep drawing performance tests, performance tests, such as bulging stamping properties of test material, to ensure product quality and a high pass rate.
Die direct effects of stamping forming and precision and accuracy. Mould manufacturing costs and the effect of stamping parts long life cost and quality is an important factor. Mold design and manufacturing needs more time, that extended the new stamping production preparation time.
Die seat, and die frame, and oriented pieces of standardization and development simple mold (for small production), and composite die, and more station level into die (for large production), and development fast for die device, can reduced stamping production prepared workload and shortened prepared time, can makes applies Yu reduced stamping production prepared workload and shortened prepared time, can makes applies Yu big production of advanced stamping technology reasonable to should for small bulk more varieties production
Stamping equipment in addition to outside plate press forming with water, is used for mechanical presses. With modern high speed multi-position mechanical presses as the Center, configure the uncoiling-leveling-product collection, transportation machinery and the mould and quick set-up devices, and the use of computer controlled, can be composed of highly productive automatic press line.
Per minute produced dozens of cases, hundreds of pieces of stamping parts, completed in a short time feeding, stamping, and discharge waste processes, often personal, equipment, and the quality accident occurs. Therefore, safety is a very important problem in stamping.
