軸架沖壓工藝及模具的設(shè)計(jì)
學(xué)生姓名:李皓東 班級(jí)：0781052
指導(dǎo)老師：賀紅林
摘要:沖壓成型是金屬成型的一種重要方法，它主要適用于材質(zhì)較軟的金屬成型，可以一次成型形狀復(fù)雜的精密制件。本課題就是將軸架作為設(shè)計(jì)模型，將冷沖模具的相關(guān)知識(shí)作為依據(jù)，闡述冷沖模具的設(shè)計(jì)過(guò)程。
首先，對(duì)軸架的工藝性能進(jìn)行分析，提出了三種可行的沖壓工藝方案。通過(guò)對(duì)三種方案的分析比較，最終確定采用第二種方案，選定“沖孔-彎曲-落料，級(jí)進(jìn)模生產(chǎn)”的沖壓工藝路線。然后，按選定的工藝路線進(jìn)行主要參數(shù)的工藝計(jì)算。確定模具的結(jié)構(gòu)。即模架型式、導(dǎo)向方式、毛坯定位、卸料、推料、壓料、出件方式等。隨后，確定模具主要零部件的結(jié)構(gòu)與尺寸。并在此基礎(chǔ)上繪制裝配圖和零件工作圖。最后，確定壓力機(jī)類型及主要參數(shù)。以達(dá)到預(yù)期效果。

Axis frame stamping process and die design
Student name:Li Haodong Class：0781052
Supervisor:He Honglin
Abstract: Stamping is an important method of metal forming, it is mainly applied to relatively soft metal forming, can be a molding of precision parts of complex shape. This topic is to stand as a design axis model, Die related knowledge as a basis to explain the design process of Die.
First, the performance of the shaft frame analysis of the process, put forward three possible solutions stamping process. Through analysis and comparison of three programs, and ultimately determine the use of the second option, select "Punching - Bending - Blanking, progressive die production of" stamping process route. Then, according to the selected process route for the main parameters of the process calculation. Determine the structure of the mold. The mold pattern, oriented approach, rough positioning, unloading, pushing material, press materials, the pieces of methods. Subsequently, to determine the main components of the mold structure and size. On this basis, assembly drawing and parts on the working drawings. Finally, determine the type and presses the main parameters. To achieve the desired effect.
