The Numerical Design System Of Precision Forging Die Of Straight Bevel Gear For Automobile Series Parts

Ever since these years, automobile manufacturing has gotten a great advancement. In the same time, its development puts forward a higher requirement to automobile parts manufacturing. At present, the development level is laggard in national mostly automobile parts enterprises. Total technique plane is not high. Die exploitation only aims at a single part. How to change currently actuality in more economic and efficiency methods becomes a very important study task for automobile parts manufacturing now.There are many parts in automobile parts which have similar watch and few differences in only several key sizes or types. We define them as series parts.Product watch, mechanical capability and design precision are super crucial factors in automobile parts produce. There are prodigious relation between these three factors with mould design, mould manufacture and debugging precision. This article exploits a numerical design system of precision forging die of straight bevel gear for automobile series parts to try to provide a more economic and higher efficient method for the die exploitation of automobile parts. This system spreads research through looking for series parts dies as a break. It regards Pro/E system as exploitation flat and takes Pro/toolkit and VC++ as tools.This article regards representative straight bevel gear as a example in automobile series parts and detailedly states the total exploitation process. This system applies parametric and numeric in the course of die exploitation of straight bevel gear. We can obtain all dies of this series from one suit of die template by amending parameters. In the process of exploitation, we use a new idea of "pitch cone radius not modification, reference cone angle modification." and order function of "Program" of Pro/E system to reach parametrical control of assembles of die. The towards of dentiform line is controlled through the standard relation of involute. This system conquers a disadvantage that die cavity from Pro/E system can't be controlled through parameter control.In the exploitation process of the interfaces of the system, this article puts up exploitation with synchronous mode of Pro/toolkit language, which lets this system run more steadily. In the same time, "UI" dialog boxes and menus with same style are gotten. This article designs facility and applied Human-Computer Interactional interfaces, which greatly increases the use and management rate of this system.This article simulates the entire production process of product with "DEFORM" CAE software. In addition, it simulates three different male dies (no convex, cylinder convex, sphere convex) because these three male dies have different infections to figuration load and effect in total shape procession of product. Sphere convex is regarded as the best project from the analysis results about stress distribution andLoad-Journey curve. The simulation results show that sphere convex project can effectively improve fluidity of metal, depress forging press and product favorable parts.This system combines parametric and numeric and management functions of Pro/E system with simulation function of DEFORM in dummy manufacture. These functions are used in die design and dummy production of automobile series parts, which improves die exploitation efficiency and management efficiency of die subassembly. This system solves existent disadvantages of traditional exploitation means. This system affords preferable instructional effect for die farther exploitation of automobile series parts.
