【導(dǎo)讀】本次設(shè)計主要設(shè)計了沖壓模具中的落料模具和彎曲模具。經(jīng)過老師的提示和。指導(dǎo)，我首先分析制件的工藝性，根據(jù)工件的工藝尺寸，算出沖壓力，選壓力機(jī)，沖壓力，最后用CAD、ProE畫圖。本次設(shè)計是把一個鋼板沖壓成一個帶缺口的圓。了大學(xué)期間所學(xué)的一切專業(yè)知識，最終設(shè)計出了比較理想的兩套模具。就直接沖裁，彎曲模具根據(jù)材料的彎曲特性，算出彎曲前得半徑，設(shè)計凸凹模，用，讓我對理論應(yīng)該與實(shí)踐相結(jié)合有進(jìn)一步的理解了、也鍛煉了自己提出了問題，分析問題和解決問題的能力。

　　

【正文】 extremely wide range of applications in the industrial sector. Now, technology has bee a country39。s products in the manufacture of the die level one of the important symbols of, research and development of mould technology, promoting the development of the national economy has a special significance. Mold industry to promote the development and the improvement of the quality of industrial production, and to have a great economic benefit, resulting each country attaches great importance to and appreciated. In Japan, mould was known as into the motivity of affluent society, in Germany called Kings in the metal processing industry, in Romania as mold is gold. So it can be asserted, as the rapid development of industrial production, mould industry position in the national economy will be growing, mold technology will also continue to develop and play an increasingly important role in the development of the national economy. Mold is the content of high technology products, is designed for industrial production, and for a specific product is special production process 洛陽理工學(xué)院畢業(yè)設(shè)計論文 33 equipment, with the development of industrial products to diversify, mold production, material from the shape, size, quantity, structure, accuracy, conditions of use and terms of life, towards diversified development trends are being increasingly apparent. Single piece production mold is essentially according to the order contract, therefore, mold product diversity and single piece production technique features very prominent. Therefore, design, technology, process and equipment of the factory and management, has to adapt to the characteristics of this technology. Most sophisticated die requires highprecision machining, testing devices require high precision. Mold processing technology of mechanical, electronic and chemical and optical industry technical elite. At the same time, die reliance on skilled craftsmen is far greater than that of other processing industries. Therefore, advanced technology and skilled techniques rely on the mold technical characteristics of the product. With the rapid development of technology, especially information technology, and other hightech applications in mould design and manufacture an increasingly widespread and increasingly demanding hightech made to die, die of hightech features will bee increasingly apparent, and for skilled techniques rely on will gradually fade. As a basis for industrial production technology and equipment, mold occupy an important position in the national economy, mold technology has also bee a country39。s level of product manufacturing one of the important symbols. Since the 80 39。s, China39。s mould industry development was very rapid. Rapid development of the national economy put increasingly higher demands on the mould industry, also provided a great impetus for its development. Over the years, China die and mould industry has been 15% the growth rate of around rapid development. At present, more than 17,000 more mold production plant in China, numbers of employees is about more than 500,000. 1999 China mold industrial output value reached billion yuan. Gross output value of industrial enterprises accounted for captive use in twothirds, as the sale of goods of about onethird. 洛陽理工學(xué)院畢業(yè)設(shè)計論文 34 In die and mould industry in GDP, stamping mould design about 50%, about 33% plastic mould, die about 6%, other types of mould about 11%. Since reform and opening up, China die and mould industry enterprises ownership position of tremendous changes have taken place. In addition to Stateowned professional mould factory, mould manufacturers of other forms of ownership, including collective enterprises, joint ventures, whollyowned enterprises and private enterprises, have achieved rapid development, collective Mold, and private enterprises in Guangdong and Zhejiang provinces have developed most rapidly. For example, and huangyan area, Ningbo, Zhejiang, collective enterprises and private enterprises engaged in mold manufacturing up to thousands of homes, became the wellknown mould town and one of the most dynamic region in the development. In Guangdong, some group panies and the rapid rise of township and town enterprises, to enhance the market petitiveness of its products , joining the die manufacturing inputs, for example, kelon, midea, KONKA and power group has established its own mould manufacturing center. Sinoforeign joint ventures and wholly foreignowned enterprises concentrated in coastal industrialized areas of the mould, is now on thousands of homes. For example, Wuxi micro research is a Japanowned enterprises, employees have more than 200 employees, with precision CNC mold processing equipment more than more than 60, 1998 the die output of more than 200 million Yuan. Technical level of China die and mould industry have also made considerable progress in recent years. At present, the country can produce precision precision multiposition progressive die for up to 2 microns, maximum number of stations has reached 160, life 1~2 billions. In a large plastic mould, now has been able to produce 48inch TV plastic shell and of large capacity washing machine plastic moulds, as well as auto mold such as bumpers, dashboards as a whole. In terms of precision plastic mo ld, the domestic plastic mould, has been able to produce a camera multiplecavity mould and plastic mould and small modulus gear. In terms of large precision 洛陽理工學(xué)院畢業(yè)設(shè)計論文 35 diecasting die for the plex, is capable of producing escalators in China overall pedal die and Diecasting die for automobile rear axle gearbox. In terms of auto mould, is now part of Panel die manufacturing new cars. Other types of mold, such as segmented radial tire mold, aluminum alloy and plastic door and window profile Extrusion die, also reach
