The use of puter automatic programming, control CNC machine tools to improve the efficiency in the use and scope. In recent years, has developed a puter to timesharing by the way a group of direct management and control of CNC machine tools NNC system. With the development of puter technology, puters have gradually into the mold in all areas, including design, manufacturing and management. I。s to high speed, launch technology, precision, security, development of the second stage. Continue to emerge in this process a variety of high efficiency, business life, highprecision multifunctional automatic school to help with. Represented by the number of working places as much as other progressive die and dozens of multistation transfer station module. On this basis, has developed both a 北方民族大學(xué)學(xué)士學(xué)位論文 25 continuous pressing station there are more slide forming station of the press bending machine.

The 19th century, with the arms industry (gun39。 in aircraft, automobiles, agricultural machinery and radio industries, the proportion exceeded 60%. Such as aircraft manufacturing, the use of a certain type of fighter dies more than 30,000 units, of which the host 8000 sets, 2020 sets of engines, auxiliary 20 000 sets. From the output of view, since the 8039。第 1卷 .北京：機(jī)械工業(yè)出版社， 1997. [9] 強(qiáng)毅 .《技術(shù)制圖》國家標(biāo)準(zhǔn)應(yīng)用指南 .北京：機(jī)械工業(yè)標(biāo)準(zhǔn)化技術(shù)服務(wù)部， 1995.

With mold ponents, with high efficiency, good quality, low cost, saving energy and raw materials and a series of advantages, with the mold workpieces possess high accuracy, high plexity, high consistency, high productivity and low consumption , other manufacturing methods can not match. Have already bee an important means of industrial production and technological development. The basis of the modern industrial economy. The development of modern industrial and technological level depends largely on the level of industrial development die, so die industry to national economic and social development will play an increasing role. March 1989 the State Council promulgated on the current industrial policy decision points in the mold as the machinery industry transformation sequence of the first, production and capital construction of the second sequence (after the largescale power generation equipment and the corresponding power transmission equipment), establish tooling industry in an important position in the national economy. Since 1997, they have to mold and its processing technology and equipment included in the current national focus on encouraging the development of industries, products and technologies catalog and to encourage foreign investment industry directory. Approved by the State Council, from 1997 to 2020, more than 80 professional mold factory owned 70% VAT refund of preferential policies to support mold industry. All these have fully demonstrated the development of the State Council and state departments tooling industry attention and support. Mold around the world about the current annual output of 60 billion . dollars, Japan, the United States and 北方民族大學(xué)學(xué)士學(xué)位論文 23 other industrialized countries die of industrial output value of more than machine tool industry, beginning in 1997, China39。謝謝老師！ 由于我的水平有限 ,設(shè)計(jì)書中難免有缺點(diǎn)和錯誤 ,敬請讀者批評指正?，F(xiàn)在才明白這是非常必要的，我 們似乎更加專業(yè)了，當(dāng)然我們以后在這方面要更加關(guān)注和學(xué)習(xí)。 經(jīng)過這段時間的學(xué)習(xí)， 從收集資料，擬訂多種方案，分析比較技術(shù)方案，到?jīng)_壓設(shè)備的選擇再到板料設(shè)計(jì)及模具總體結(jié)構(gòu)設(shè)計(jì)等環(huán)節(jié)，使 我更深刻的理解了 拉深 模具的基礎(chǔ)知識，通過實(shí)踐操作所掌握的是無法通過上課可以學(xué)到的 ， 同時又讓我溫習(xí)了solidworks和 ATUOCAD的制圖知識，熟練了 cad的操作技巧，加強(qiáng)了我與同學(xué)間的學(xué)習(xí)交流，這些都是非?？少F的。 利用 solidworks 或 AUTOCAD 完成裝配圖和部分零件圖 見附錄 3 第 7 章 結(jié)論 北方民族大學(xué)學(xué)士學(xué)位論文 20 收獲及體會 充滿艱辛和快樂 的 畢業(yè) 設(shè)計(jì)，眼看就要結(jié)束了。 (5)零件的檢測、驗(yàn)收、包裝等要求。 (3)零件的 尺寸公差 、形狀和位置公差 。 技術(shù)要求主要包含以下內(nèi)容 ： (1)零件的材料及毛坯要求。 (4)毛坯 面與加工面應(yīng)分別標(biāo)注。 (2)一般尺寸應(yīng)從工藝基準(zhǔn)出發(fā)標(biāo)注。標(biāo)注尺寸時，既要考慮設(shè)計(jì)要求，又要考慮工藝要求。 (2)工藝 基準(zhǔn) 根據(jù)零件的加工、測量要求所選定的基準(zhǔn) 。在選擇尺寸基準(zhǔn)時，必須根據(jù)零件在機(jī)器中的作用、 裝配 關(guān)系、以及零件的加工方法、測量方法等情況來 確定。 1．尺寸基準(zhǔn) 北方民族大學(xué)學(xué)士學(xué)位論文 19 度量尺寸的起點(diǎn)，稱為尺寸基準(zhǔn)。 零件圖上所標(biāo)注的尺寸不但要滿足設(shè)計(jì)要求，還應(yīng)滿足生產(chǎn)要求。主要包括： （ 1） 表面粗糙度 （ 2） 公差與配合 （ 3） 形狀與位置公差 （ 4） 零件的表面處理、熱處理 、檢驗(yàn)要求等 4．標(biāo)題欄 說明零件的名稱、材料、數(shù)量、日期、圖的編號、 比例 以及描繪、審核人員簽字等 。 2． 完整的尺寸 用以確定零件各部分的大小和位置。因此，它是指導(dǎo)零件生產(chǎn)的重要技術(shù)文件 。 . 北方民族大學(xué)學(xué)士學(xué)位論文 18 零件圖的繪制 零 件圖是表達(dá)單個零件形狀、大小和特征的圖樣，也是在制造和檢驗(yàn)機(jī)器零件時所用的圖樣，又稱零件工作圖。 檢驗(yàn)要求 裝配過程中及裝配后必須保證其精度的各種檢驗(yàn)方法 。 、部件序號、標(biāo)題欄和明細(xì)欄 按國家標(biāo)準(zhǔn)規(guī)定的格式繪制 標(biāo) 題欄 和 明細(xì)欄 ，并按一定格式將零、部件進(jìn)行編號，填寫標(biāo)題欄和明細(xì)欄 。 標(biāo)注出反映產(chǎn)品或部件的規(guī)格、外形、裝配、安裝所需的必要 尺 寸 和一些重要尺寸。 在產(chǎn)品或部件的 設(shè)計(jì) 過程中，一般是先設(shè)計(jì)畫出裝配圖，然后再根據(jù)裝配圖進(jìn)行零件設(shè)計(jì)，畫出 零 件圖 ；在產(chǎn)品或部件的制造過程中，先根據(jù)零件圖進(jìn)行零件加工和檢驗(yàn)，再按照依據(jù)裝配圖所制定的裝配工藝規(guī)程將零件裝配成機(jī)器或部件；在產(chǎn)品或部件的使用、維護(hù)及維修過程中，也經(jīng)常要通過裝配圖來了解產(chǎn)品或部件的工作原理及構(gòu)造。
