1、模具设计与制造外文翻译 The mold designing and manufacturing The mold is the manufacturing industry important craft foundation, in our country, the mold manufacture belongs to the special purpose equipment manufacturing industry. China although very already starts to make the mold and the use mold, but long-ter
2、m has not formed the industry. Straight stabs 0 centuries 80s later periods, the Chinese mold industry only then drives into the development speedway. Recent years, not only the state-owned mold enterprise had the very big development, the three investments enterprise, the villages and towns (indivi
3、dual) the mold enterprises development also rapid quietly. Although the Chinese mold industrial development rapid, but compares with the demand, obviously falls short of demand, its main gap concentrates precisely to, large-scale, is complex, the long life mold domain. As a result of in aspect and s
4、o on mold precision, life, manufacture cycle and productivity, China and the international average horizontal and the developed country still had a bigger disparity, therefore, needed massively to import the mold every year . The Chinese mold industry must continue to sharpen the productivity, from
5、now on will have emphatically to the profession internal structure adjustment and the state-of-art enhancement. The structure adjustment aspect, mainly is the enterprise structure to the specialized adjustment, the product structure to center the upscale mold development, to the import and export st
6、ructure improvement, center the upscale automobile cover mold forming analysis and the structure improvement, the multi-purpose compound mold and the compound processing and the laser technology in the mold design manufacture application, the high-speed cutting, the super finishing and polished the
7、technology, the information direction develops . The recent years, the mold profession structure adjustment and the organizational reform step enlarges, mainly displayed in, large-scale, precise, was complex, the long life, center the upscale mold and the mold standard letter development speed is hi
8、gher than the common mold product; The plastic mold and the compression casting mold proportion increases; Specialized mold factory quantity and its productivity increase; The three investments and the private enterprise develops rapidly; The joint stock system transformation step speeds up and so o
9、n. Distributes from the area looked, take Zhejiang Delta and Yangtze River delta as central southeast coastal area development quickly to mid-west area, south development quickly to north. At present develops quickest, the mold produces the most centralized province is Guangdong and Zhejiang, places
10、 such as Jiangsu, Shanghai, Anhui and Shandong also has a bigger development in recent years. Although our country mold total quantity had at present achieved the suitable scale, the mold level also has the very big enhancement, after but design manufacture horizontal overall rise and fall industry
11、developed country and so on Yu De, America, date, France, Italy many. The current existence question and the disparity mainly display in following several aspects: (1) The total quantity falls short of demand Domestic mold assembling one rate only, about 70%. Low-grade mold, center upscale mold asse
12、mbling oneself rate only has 50% about. (2) the enterprise organizational structure, the product structure, the technical structure and the import and export structure does not gather in our country mold production factory to be most is from the labor mold workshop which produces assembles oneself (
13、branch factory), from produces assembles oneself the proportion to reach as high as about 60%, but the overseas mold ultra 70% is the commodity mold. The specialized mold factory mostly is large and complete, small and entire organization form, but overseas mostly is small but, is specially small an
14、d fine. Domestic large-scale, precise, complex, the long life mold accounts for the total quantity proportion to be insufficient 30%, but overseas in 50% above 2022 years, ratio of the mold import and export is 3.7:1, the import and export balances the after net import volume to amount to 1.32 billi
15、on US dollars, is world mold net import quantity biggest country . (3) The mold product level greatly is lower than the international standard The production cycle actually is higher than the international water broad product level low mainly to display in the mold precision, cavity aspect and so on
16、 surface roughness, life and structure. (4) Develops the ability badly, economic efficiency unsatisfactory our country mold enterprise technical personnel proportion low The level is lower, also does not take the product development, and is frequent in the passive position in the market. Our country
17、 each mold staff average year creation output value approximately, ten thousand US dollars, overseas mold industry developed country mostly 15 to10, 000 US dollars, some reach as high as 25 to10, 000 US dollars, relative is our country quite part of molds enterprises also continues to use the worksh
18、op type management with it, truly realizes the enterprise which the modernized enterprise manages few To create the above disparity the reason to be very many, the mold long-term has not obtained the value besides the history in as the product which should have, as well as the most state-owned enter
19、prises mechanism cannot adapt the market economy, but also has the following several reasons: . (1) Country to mold industry policy support dynamics also insufficiently Although the country already was clear about has promulgated the mold profession industrial policy, but necessary policy few, carri
20、ed out dynamics to be weak. At present enjoyed the mold product increment duty enterprise nation 185; the majority enterprise still the tax burden is only overweight. The mold enterprise carries on the technological transformations introduction equipment to have to pay the considerable amount the ta
21、x money, affects the technology advancement, moreover privately operated enterprise loan extremely difficult. (2) Talented person serious insufficient, the scientific research development and the technical attack investment too urine mold profession is the technology, the fund, the work crowded indu
22、stry, along with the time progress and the technical development, grasps the talented person which and skilled utilizes the new technology exceptionally short, the high-quality mold fitter and the enterprise management talent extremely is also anxious. Because the mold enterprise benefit unsatisfact
23、ory and takes insufficiently the scientific research development and the technical attack, the scientific research unit and the universities, colleges and institutes eye stares at is creating income, causes the mold profession invests too few in the scientific research development and the technical
24、attack aspect, causes the mold technological development step doe not to be big, progresses does not be quick. (3) The craft equipment level is low, also is not good, the using factor is low. Recent years ,our country engine bed profession progressed quickly, has been able to provide the quite compl
25、ete precision work equipment, but compared with the overseas equipment, still had a bigger disparity. Although the domestic many enterprises have introduced many overseas advanced equipment, but the overall equipment level low are very more than the overseas many enterprises. As a result of aspect t
26、he and so on system and fund reason, introduces the equipment not necessary, the equipment and the appendix not necessary phenomenon are extremely common, the equipment utilization rate low question cannot obtain the comparatively properly solution for a long time . (4) Specialization, standardizati
27、on, commercialized degree low, the cooperation ability Because receives large and complete small and entire the influence since long ago, mold specialization level low, the specialized labor division is not careful, the commercialized degree is low. At present domestic every year produces mold, comm
28、odity mold minister 40% about, other for from produce uses for oneself. Between the molds enterprise cooperates impeded, completes the comparatively large-scale mold complete task with difficulty. Mold standardization level low, mold standard letter use cave rare is low also to the mold quality, the
29、 cost has a more tremendous influence, specially has very tremendous influence. (5) To the mold manufacture cycle) the mold material and the mold correlation technology fall The mold material performance, the quality and the variety question often can affect the mold quality, the life and the cost,
30、the domestically produced molding tool steel and overseas imports the steel products to compare has a bigger disparity. Plastic, plate, equipment energy balance, also direct influence mold level enhancement. At present, our country economy still was at the high speed development phase, on the intern
31、ational economical globalization development tendency is day by day obvious, this has provided the good condition and the opportunity for the our country mold industry high speed development. On the one hand, the domestic mold market will continue high speed to develop, on the other hand, the mold m
32、anufacture also gradually will shift as well as the transnational group to our country carries on the mold purchase trend to our country extremely to be also obvious. Therefore, will take a broad view the future, international, the domestic mold market overall development tendency prospect will favo
33、r, estimated the Chinese mold will obtain the high speed development under the good market environment, our country not only can become the mold great nation, moreover certainly gradually will make the powerful nation to the mold the ranks to make great strides forward. 15 period, the Chinese mold i
34、ndustry level not only has the very big enhancement in the quantity and the archery target aspect, moreover the profession structure, the product level, the development innovation ability, enterprises system and the mechanism as well as the technology advancement aspect also can obtain a bigger deve
35、lopment . The mold technology has gathered the machinery, the electron, chemistry, optics, the material, the computer, the precise monitor and the information network and so on many disciplines, is a comprehensive nature multi-disciplinary systems engineering. The mold technology development tendenc
36、y mainly is the mold product to larger-scale, precise, more complex and a more economical direction develops, the mold product technical content unceasingly enhances, the mold manufacture cycle unceasingly reduces, the mold production faces the information, is not having the chart, is fine, the auto
37、mated direction develops, the mold enterprise to the technical integration, the equipment excellent, is producing approves the brand, the management information, the management internationalization direction develops. Mold profession in 十15 period needs to solve the key essential technology should b
38、e the mold information, the digitized technology and precise, ultra fine, high speed, the highly effective manufacture technology aspect breakthrough Along with the national economy total quantity and the industry product technology unceasing development, all the various trades and occupations to th
39、e mold demand quantity more and more big, the specification more and more is also high. Although mold type many, but its development should be with emphasis both can meet the massive needs, and has the comparatively high-tech content, specially at present domestic still could not be self-sufficient,
40、 needs the massive imports the mold and can represent the development direction large-scale, precise, is complex, the long life mold. Standard letter type, quantity, level and the production of the mold have significant influence to the entire mold profession development. Therefore, some important m
41、old standard letters also must prioritize, moreover its development speed should quickly to the mold development speed, like this be able unceasingly to raise our country mold standardization level, thus improves the mold quality, reduces the mold production cycle, reduces the cost. Because our coun
42、try mold product holds the bigger price superiority in the international market, therefore regarding the exportation prospect good mold product also should take key develops. According to the above required quantity big, the technical content is high, represents the development direction, the export
43、 prospect good principle choice prioritize product, moreover chooses the product to have at present to have the certain technology base, belongs has the condition, has the product which the possibility develops . Die trend 1. Mold CAD / CAE / CAM being integrated, three-dimensional, intelligent and
44、network direction (1) Mold software features integrated Die software features of integrated software modules required relatively complete, while the function module using the same data model, in order to achieve Syndicated news management and sharing of information to support the mold design, manufa
45、cture, assembly, inspection, testing and production management of the entire process to achieve optimal benefits. Series such as the UK Delcams software will include a surface / solid geometric modeling, engineering drawing complex geometry, advanced rendering industrial design, plastic mold design
46、expert system, complex physical CAM, artistic design and sculpture automatic programming system, reverse engineering and complex systems physical line measurement systems. A higher degree of integration of the software includes: Pro / ENGINEER, UG and CATIA, etc. Shanghai Jiao tong University, China
47、 with finite element analysis of metal plastic forming systems and Die CAD / CAM systems; Beijing Beihang Haier Software Ltd. CAXA Series software; Jilin Gold Grid Engineering Research Center of the stamping die mold CAD / CAE / CAM systems . (2) Mold design, analysis and manufacture of three-dimens
48、ional Two-dimensional mold of traditional structural design can no longer meet modern technical requirements of production and integration. Mold design, analysis, manufacturing three-dimensional technology, paperless software required to mold a new generation of three-dimensional, intuitive sense to
49、 design the mold, using three-dimensional digital model can be easily used in the product structure of CAE analysis, tooling manufacturability evaluation and CNC machining, forming process simulation and information management and sharing. Such as Pro / ENGINEER, UG and CATIA software such as with parametric, feature-based, all relevant characteris
