Widely used in motor vehicles, machinery, aerospace, aviation, light industry, electronics, electric appliances, instruments and other industries. With the rapid development of China's automobile industry, The car's performance to improve, Auto parts of high precision, complicated shape of forging an increasing demand for, Forging new craft, material, energy saving technology province technology development for new type of car parts production is especially important. Our country stamping die in the number no matter, or in quality, technology and ability are already has great development, But with the national economy needs and the advanced world level, compared toa gap still, Some large, sophisticated, complex, the long life of high-grade die every year in the importation of large still, Especially in high-grade car covering mould, at present still mainly rely on imports. The paper is an inert round of forging production, Processing techniques, Design and manufacturing, some mould, including, fall round of forgings upsetting, eventually forging, and trimming punching production processing again, trimming punching the design of posite film.
