【正文】 als sent from the mold after the entrance, step in the strictly controlled conditions, accuracy, forming process in accordance with the order arranged by the continuous pressing of the station, at the last station, or by punching cut off, the system can be washed to meet the requirements of stamping products. To ensure multiposition progressive die work, die must have a highprecisionoriented and accurate fixed pitch system, equipped with automatic feeding, automatic parts, safety testing and other devices is characterized by progressive die for high production efficiency, production short cycle, the operator takes less well suited for mass production. Progressive Die Design is one of the main points of the rough layout, layout program on the utilization of materials, stamping and mold processing technology of the structure and longevity have a significant impact. This time, the graduation project from the practice factory, the mold structure is also more mon, is an exercise for us beginners. In the design of the mold die design were summarized in the past the general methods and procedures monly used in mold design formula, data, die structure and ponents. The basis of previously learned to integrate the graduate design programs in the past. In this graduation design is also used in the CAD, UG and other software. Because the limited practical experience and theoretical techniques, design errors and deficiencies hope that teachers criticized the correction.Keywords: Progressive die, layout, process analysis, mold manufacturing 目 錄引言在這次畢業(yè)設(shè)計(jì)中同時(shí)還用到了CAD、UG等軟件。級(jí)進(jìn)模設(shè)計(jì)的要點(diǎn)之一就是毛坯排樣,排樣方案對材料的利用率、沖壓加工的工藝性以及模具的結(jié)構(gòu)和壽命等有著顯著的影響。多工位級(jí)進(jìn)模是在普通級(jí)進(jìn)模的基礎(chǔ)上發(fā)展起來的一種高精度、高效率、長壽命的模具,是技術(shù)密集型模具的重要代表,是沖模發(fā)展方向之一。 畢業(yè)設(shè)計(jì)用紙中文摘要目前,我國經(jīng)濟(jì)仍處于高速發(fā)展階段,國際上經(jīng)濟(jì)全球化發(fā)展趨勢日趨明顯,這為我國模具工業(yè)高速發(fā)展提供了良好的條件和機(jī)遇。這種模具除進(jìn)行沖孔落料工作外,還可根據(jù)零件結(jié)構(gòu)的特點(diǎn)和成形性質(zhì),完成壓筋、沖窩、彎曲、拉深等成形工序,甚至還可以在模具中完成裝配工序。 本次的畢業(yè)設(shè)計(jì)課題來源于工廠的工作實(shí)踐, 模具結(jié)構(gòu)也較為常見,對于我們初學(xué)者是一種鍛煉。 由于實(shí)際經(jīng)驗(yàn)和理論技術(shù)有限,設(shè)計(jì)的錯(cuò)誤和不足
