中軸碗沖壓成形工藝與模具設(shè)計
摘 要
本設(shè)計題目為中軸碗沖壓成形工藝與模具設(shè)計，體現(xiàn)了板類沖壓零件的設(shè)計要求、內(nèi)容及方向，有一定的設(shè)計意義。通過對該零件模具的設(shè)計，進一步加強了設(shè)計者沖壓模具設(shè)計的基礎(chǔ)知識，為設(shè)計更復(fù)雜的沖壓模具做好了鋪墊并吸取了更深刻的經(jīng)驗。
本設(shè)計運用沖壓成型工藝及模具設(shè)計的基礎(chǔ)知識，首先分析了工件的成形工藝及模具成形結(jié)構(gòu)對制件質(zhì)量的影響。介紹了中軸碗沖壓模具設(shè)計時要注意的要點，通過對制件進行工藝分析，可確定制件的成形加工用一套復(fù)合模和一套沖孔模具即可。從控制制件尺寸精度出發(fā)，對中軸碗沖壓模具的各主要尺寸進行了理論計算，以確定各工作零件的尺寸，從模具設(shè)計到零部件的加工工藝以及裝配工藝等進行詳細的闡述，并應(yīng)用CAD進行各重要零件的設(shè)計。

the center bowl stamps forminghandicraft
and design for die
Abstract
The topic of this design is the center bowl stamps forming handicraft and design for die.The requirement，content and direction of the design of the stamps forming plate parts are embodied on this stamping die design. The designer’s foundation knowledge of the stamping die design is reinforced and is able to design more complex stamping die through the design.
This design the elementary knowledge which designs using the stamping formation craft and the die, first has analyzed the work piece formed craft and the die forming structure to the workpiece quality influence. Introduced the center bowl filling piece stamping die design when must pay attention to the main point, through carries on the craft analysis to the workpiece, may determine the workpiece the formed processing uses set of superposable dies and a punching die. Embarks from the control workpiece size precision, counter center bowl filling piece stamping die each main dimension has carried on the theoretical calculation, by determined each work components the size, designs from the die to the spare part processing craft as well as the assembly craft and so on carries on the detailed elaboration, and carries on each important components using CAD the design.
Key words: compound die；process analysis；processing of die parts.
