锻造模具设计
摘要
模具是机械制造业中技术先进、影响深远的重要工艺装备,具有生产效率高、材料利用率高、制件质量优良、工艺适应性好等特点,被广泛应用于汽车、机械、航天、航空、轻工、电子、电器、仪表等行业。随着我国汽车工业的迅猛发展，汽车性能不断提高，汽车零部件中对高精度、形状复杂锻件的需求量越来越大，锻造新工艺、省材、节能工艺等技术的开发对于新型汽车零件的生产尤为重要。我国冲压模具无论在数量上，还是在质量、技术和能力等方面都已有了很大发展，但与国民经济需求和世界先进水平相比，差距仍很大，一些大型、精密、复杂、长寿命的高档模具每年仍大量 进口，特别是中高档轿车的覆盖件模具，目前仍主要依靠进口。
本文主要是以轴类锻件的生产，加工工艺等，设计制造了，一些模具，包括，堕轮锻件的镦粗，终锻等后期加工模具。
首先介绍了，模具的一些简单情况，模具的分类，发展现状和趋势等，其次介绍了，零件的工艺性，毛坯的制定，镦粗，终锻模膛的设计，包括飞边槽的设计。

An inert wheel forging the design specification
Abstract
Mold is mechanical manufacturing technology advanced, profoundly important technical equipment，High production efficiency, material with high efficiency and good quality, technology parts good adaptability etc. Characteristics. 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 to a 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 mould.
Firstly introduces, die some simple case, the classification of mould, development situation and trends, Secondly introduces, the technology of parts, blank the formulation, the upsetting, and the design of the chamber forging die, Including flash slots of design, Introduced again, trimming punching the design of the composite film.
Key words: Mould, Finally bore, Flash tank, Clamp mouth, Upsetting, Trimming, punching
