1支撐板沖裁工藝及模具設(shè) 摘要：本文介紹了一種連續(xù)轉(zhuǎn)位多孔復(fù)合沖裁模具的設(shè)計(jì)，重點(diǎn)闡述了多品種中小批量生產(chǎn)中在平板上沖制密排多孔的工藝方法、模具結(jié)構(gòu)應(yīng)注意的問題。本設(shè)計(jì)運(yùn)用沖壓成型工藝及模具設(shè)計(jì)的基礎(chǔ)知識(shí)，首先分析了工件的成形工藝及模具成形結(jié)構(gòu)對(duì)制件質(zhì)量的影響。介紹了連續(xù)轉(zhuǎn)位復(fù)合沖裁模具設(shè)計(jì)時(shí)要注意的要點(diǎn)，通過對(duì)制件進(jìn)行工藝分析，可確定制件的成形加工用兩套復(fù)合模即可。從控制制件尺寸精度出發(fā)，對(duì)連續(xù)轉(zhuǎn)位復(fù)合沖裁模具的各主要尺寸進(jìn)行了理論計(jì)算，以確定各工作零件的尺寸，從模具設(shè)計(jì)到零部件的加工工藝以及裝配工藝等進(jìn)行詳細(xì)的闡述，并應(yīng)用CAD進(jìn)行各重要零件的設(shè)計(jì)。關(guān)鍵詞：板料 密排多孔 轉(zhuǎn)位連續(xù)沖裁 復(fù)合模The design of a continuous transferable lacunaris composite 2punch－mouldAbstract：The design of a continuous transferable lacunaris composite punch—mould is introdueed，and the technics，mould structure and the problems must noticed to punch close muhihode onplate in multibreed middling or small batch manufacture are dlssertated asemphases．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 gear bolt 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: plate—materiel；close multihode；transferable continuous punch;compound die.
