摘 要
本次設(shè)計(jì)了一套沖孔，落料的模具。經(jīng)過查閱資料，首先要對零件進(jìn)行工藝分析，經(jīng)過工藝分析和對比，采用沖孔落料工序，通過沖裁力，頂件力，卸料力等的計(jì)算，確定壓力機(jī)的型號。在分析對沖壓件加工的模具適用類型選擇所需的模具。得出將設(shè)計(jì)的模具類型后將模具的各個工作零件部件的設(shè)計(jì)過程表達(dá)出來。在文檔中第一部分，主要敘述了沖壓模具的發(fā)展?fàn)顩r，說明了沖壓模具的重要性與本次設(shè)計(jì)的意義，接著是對沖壓件的工業(yè)分析，完成了材料利用率的計(jì)算。在進(jìn)行沖裁工藝力的計(jì)算和沖裁模工作部分的設(shè)計(jì)計(jì)算，對選擇沖壓設(shè)備提供依據(jù)。最后是對主要零部件的選擇。
本次設(shè)計(jì)闡述了沖壓落料復(fù)合模的結(jié)構(gòu)設(shè)計(jì)及工作過程。本模具性能可靠，運(yùn)行平穩(wěn)，提高了產(chǎn)品質(zhì)量和生產(chǎn)效率，降低勞動強(qiáng)度和生產(chǎn)成本。

ABSTRACT
The design of a punching, blanking die. Through access to information, we must first process the parts analysis, technology analysis and comparison by using the punch blanking process, through the blanking force, the top pieces of force, discharge force of the calculations to determine the type presses. In the analysis of the stamping process to select the desired type of mold for the mold. Types obtained after the design of the mold die parts of the various working parts of the design process of expression.
In the first part of the document, the main account of the development of stamping die, stamping die shows the importance and significance of this design, then is the stamping industry analysis, completed the material utilization rate calculation. Calculation of force during the blanking process and the work of some of blanking die design calculation, provide the basis for the selection of stamping equipment. Finally, the choice of the main components.
The design described blanking compound die stamping design and working process.Reliable performance of the mold, smooth operation, improved product quality and production efficiency, reduce labor intensity and production costs.
Keywords: Stamping: Blanking punch: Compound Die: die structure
