奔驰机油泵壳体0件模具上模CAD/CAM
摘要：目前国外模具行业广泛采用CAD/CAM技术，并通过数控机床进行加工，大大的缩短了产品开发周期和制造周期，提高了模具的技术含量，降低了成本。相比之下，我国模具行业还有很大差距，特别是在汽车0部件生产制造方面还不具备为国产汽车(尤其是轿车)全面配套供货的能力，参与国际竞争的能力很弱。针对目前国内汽车0部件行业情况，我们必须根据国际汽车0部件工业的发展，综合分析国外经验,结合我国实际情况，采取有利措施，提高我国汽车0部件工业的竞争力。
本课题通过对机油泵壳体0件设计过程的分析，以Pro/E、AutoCAD软件为基础，进行了机油泵壳体0件模具的开发；对上模样进行了工艺分析；同时运用MasterCAM软件仿真了机油泵壳模具的数控加工，实现了从实物到生产的1体化。利用参数化实体造型的方法，突破了AutoCAD3维实体造型功能不足的局限，为汽车0部件更加高速、快捷的造型、生产提供了1种切实可行的办法。

Male Die of The Pumps Shell Parts of Benchi Automobile CAD/CAM
ABSTRACT: Now foreign mould industry has greatly shortened the mould of making period, heightened the mould of technical content and reduced the cost by making use of CAD/CAM technical and numerical control tool. To the contrary, mould industry in our country has lagged support behind, especially in the automobile part industry. Which doesnt has the ability to suppot complete parts for automobiles made in china. Chinas ability to compete with international automobile industry is weak. Considering the actual complexion in our country and the development of international automobile part industry, we must make powerful measures to improve abilities to tap product and to compete with international automobile part in dustry.
Base on commercial software-Pro/E and CAD, we open up the mould of shell of pump parts and the Process Design, simulate the numerical control with the soft of MasterCAM and also realize the process from practicality to production.The method which is created by parameters breaks through the limits in the three-dimension shaping of AutoCAD, so that a feasible method is supported.
