底座沖孔落料彎曲模具的設(shè)計
摘 要：本設(shè)計題目為底座沖孔落料彎曲成形工藝與模具設(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)計運用沖孔落料彎曲成形工藝及模具設(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。介紹了底座沖孔落料彎曲模具設(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兩套模具即沖孔落料正裝復(fù)合模和一次彎曲成形模具。從控制制件尺寸精度出發(fā)，對該底座沖孔落料彎曲模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。
關(guān)鍵詞：復(fù)合模；工藝分析；模具零部件的加工工藝。
The foundation punch holes fall the material
Curving mold the design
Abstract：The topic of this design is the foundation punch holes fall the material to be curvingforming process and die design. 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.
The design of the use of the punch holes fall the material curving forming process and die design of the basic knowledge, First, we analyze the shape of workpiece forming process and die structure of the parts quality. Introduced The foundation punch holes fall the material curving mold design to the main points of attention, through the process of parts for analysis, to determine parts of the forming die with two sets of molds are the punch holes fall the material true thing superposable die and one time form the mold curving. Embarks from the control workpiece size precision, To the foundation punch holes fall the material bending die of the main dimensions of the theoretical calculation to determine the size of the working parts. Parts from the mold design to the processing technology as well as the assembly process, such as described in detail, and the application of CAD for the design of the important parts.
Key words: compound die；process analysis；processing of die parts.
