- 電視機(jī)后蓋沖件級(jí)進(jìn)模畢業(yè)設(shè)計(jì)電視機(jī)后蓋沖件級(jí)進(jìn)模畢業(yè)設(shè)計(jì)
中文摘要：本次設(shè)計(jì)了一套級(jí)進(jìn)模。經(jīng)過查閱資料，首先要對(duì)零件進(jìn)行工藝分析，經(jīng)過工藝分析和對(duì)比，采用沖孔落料工序，通過沖裁力、頂件力、卸料力等計(jì)算，確定壓力機(jī)的型號(hào)。再分析對(duì)沖壓件加工的模具適用類型選擇所需設(shè)計(jì)的模具。得出將設(shè)計(jì)模具類型后將模具的各工作零部件設(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(duì)沖壓件的工藝分析，完成了工藝方案的確定。第二部分，對(duì)零件排樣圖的設(shè)計(jì)，完成了材料利用率的計(jì)算。再進(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(duì)選擇沖壓設(shè)備提供依據(jù)。最后對(duì)主要零部件的設(shè)計(jì)和標(biāo)準(zhǔn)件的選擇，
為本次設(shè)計(jì)模具的繪制和模具的成形提供依據(jù)，以及為裝配圖各尺寸提供依據(jù)。通過前面的設(shè)計(jì)方案畫出模具各零件圖和裝配圖。 本次設(shè)計(jì)完成沖模分析與設(shè)計(jì)，繪制整套裝配圖及零件圖。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(dòng)強(qiáng)度和生產(chǎn)成本

Abstract：This design carries on blanking, the piercing progressive dies design. The article has briefly outlined the press die at present development condition and the tendency. It has carries on the detailed craft analysis and the craft plan determination to the product. According to general step which the press die designs, calculated and has designed on this set of mold main spare part, for example: The punch, the matrix, the punch plate, the backing strip, the matrix plate, stripper plate, stop pin, pilot pin and so on. The die sets uses the standard mould bases, has selected the appropriate press equipment. In the design has carries on the essential examination computation to the working elements and the press specification. In addition, this die employs the finger stop pin and the hook shape stop pin. The mold piercing and blankin...
