墊板沖壓模具設計
摘要：本設計題目為墊板沖壓成形工藝與模具設計，體現(xiàn)了板類沖壓零件的設計要求、內容及方向，有一定的設計意義。通過對該零件模具的設計，進一步加強了設計者沖壓模具設計的基礎知識，為設計更復雜的沖壓模具做好了鋪墊并吸取了更深刻的經驗。
本設計運用沖壓成型工藝及模具設計的基礎知識，首先分析了工件的成形工藝及模具成形結構對制件質量的影響。介紹了墊板沖壓模具設計時要注意的要點，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合模即可。從控制制件尺寸精度出發(fā)，對墊板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，并應用CAD進行各重要零件的設計。
關鍵詞：復合模；工藝分析；模具零部件的加工工藝。
The pad stamps forminghandicraft and design for die
Abstract：The topic of this design is the pad 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 pad 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. Embarks from the control workpiece size precision, counter gear bolt 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.
