摘要:擋片來源于機(jī)車配件有限公司連接設(shè)備上的一個(gè)零件，材料為10鋼。本課題首先從工藝的合理性出發(fā)，分析了擋片的結(jié)構(gòu)，精度等特點(diǎn)，然后在滿足加工精度的基礎(chǔ)上充分考慮節(jié)約成本確定了擋片最優(yōu)化的沖裁加工工序，通過對(duì)制件的形狀特點(diǎn)分析，特別是借助計(jì)算機(jī)對(duì)排樣方案的研究，最終提出了交叉對(duì)排的最佳排樣方案，從而有效地提高了材料利用率，降低了生產(chǎn)成本，提高了經(jīng)濟(jì)效益；同時(shí)結(jié)合加工特點(diǎn)，通過對(duì)模具各零件內(nèi)部結(jié)構(gòu)的優(yōu)化，改進(jìn)了加工工藝方案，方便了加工，減少了工時(shí)，起到了節(jié)能增效作用。針對(duì)擋片比較薄，產(chǎn)量較大等特點(diǎn)，最終設(shè)計(jì)出了這一副精度較高的復(fù)合模作為擋片零件模具，并完成了整副模具的裝配圖和非標(biāo)準(zhǔn)件的零件圖。

Abstract:The components originate locomotive fitting Limited company interconnection equipment's components, the material are 10 steel. 

　　　This topic first embarked from the craft rationality, analyzes has kept off the piece the structure, characteristics and so on precision, then in satisfied the working accuracy in the foundation to consider fully saved the cost to determine kept off the piece optimization the blanking working process, through to workpiece's shape characteristic analysis, specially drew support from the computer to the row of type plan research, proposed finally intersected to the row of best platoon type plan, thus raised the material use factor effectively, reduced the production cost, raised the economic efficiency. 

　　　Simultaneously unifies the processing characteristic, through to the mold various components internal structure's optimization, improved the processing craft plan, has facilitated the processing, reduced the man-hour, played the energy conservation synergized action. In view of keeps off the piece to be quite thin, the output is big and so on characteristics, designed this precision high superposable die achievement to keep off the piece components mold finally, and has completed the entire vice-mold's assembly drawing and the non-standard letter detail drawing.

Key words: Ramming craft；Economic efficiency；Arranges the quadrat law；Superposable die
