From the earliest handdrawing, and now the widespread use of puteraided design for product design, and later there will appear a more advanced design tools. The design on the main application of advanced graphics software, such as CAXA,CAD,Proe and so on. Secondly, the modern equipment industry in the mold industry is a technologyintensive, capitalintensive,high input of industry, and it is an integral part of the processing equipment industry. Mold industry and the national economy must adapt to the pillar industries such as machinery, automobile, electronics, munications, electronics, petrochemical, construction. The mold from the pillar industry needs, we can see the mold industry has an important position. Highprecision, high plexity, high consistency, high productivity and low consumption of other processed products that can not be pared with the mold. In the die design of cold stamping die design is avery important issue. The design mainly through the cylindrical part of the drawing, bulging process analysis and calculation, deeper understanding and application of the position of the mold and molding process requires the design of its mold. This design uses diagonal pillar die sets, the use of sliding guide pins and bushings and orientation. Key words: cold pressing, mold, cylindershaped, stretching, bu lging 設(shè)計(jì) （論文）專用紙 第 5 頁 全套設(shè)計(jì)，請加 12401814 設(shè)計(jì) （論文）專用紙 第 1 頁 目 錄 前 言 ........................................................................................................................................................................1 第一章 緒論 ..........................................................................................................................................................2 沖壓工藝的特點(diǎn)及應(yīng)用 ..............................................................................................................................2 沖壓工藝的基本工序及模具 .....................................................................................................................3 沖壓工藝技術(shù)的發(fā)展現(xiàn)狀及方向 .............................................................................................................4 第二章．零件的工藝性分析 ..................................................................................................................................9 對沖壓件的工藝分析 ................................................................................................................................9 確定工藝方案 .......................................................................................................................................... 10 判斷直徑為 34 的圓能否通過脹形成形 ....................................................................................... 10 毛坯尺寸計(jì)算 ................................................................................................................................... 13 計(jì)算拉深次數(shù) ................................................................................................................................... 14 排樣方式和利用率的計(jì)算 .............................................................................................................. 15 板材的選用 ....................................................................................................................................... 16 沖壓工序性質(zhì)和工序次數(shù)的選擇 ................................................................................................. 16 第三章 模具結(jié)構(gòu)分析 ......................................................................................................................................... 21 確定模具的類型 ...................................................................................................................................... 21 采用彈簧系統(tǒng)提供脹形力 .............................................................................................................. 21 采用橡皮提供脹形力 ...................................................................................................................... 22 零件的定位方式 ....................................................................................................... 錯(cuò)誤 !未定義書簽。 卸料力及壓邊力的計(jì)算 ......................................................................................................................... 24
