In recent years, accompanying the swift and violent development of manufacturing industry of our country aviation and auto industry, punch mould is in every year with of 20% add fast progress. Punch mould is the tooling with punch indispensable production, it is technology intensive product. Be designed with the mould and make efficiency of the quality of stamping workpiece, production and manufacturing cost have immediate concern. If be in life of a model, periodic the shortest, change is the most frequent is automobile body, design and make what the key that automobile body develops depends on mould of automobile body punch, occupy a car to develop the 2/3 of time about, it is the crucial factor that restricts new model to appear on the market quickly. Be in our country, of market of mould of the high end in importing a mould to occupy home 50% the left and right sides. With large, nicety, complex advanced level photograph compares the respect of hi-tech content mould that is a delegate and international, we still have 5~10 year right-and-left difference. Inside punch mould production industry, main show is in difference precision, life, production cycle and the respect such as use stability and dependability, what mould digitlization designs production technology is backward it is one of the mainest reasons that cause a product to lag behind. If where,finite development delivers to mould of user high quality inside cycle, company of need punch pattern undertakes improvement from technology and management. Mould digitlization design is made reach enterprise informatization to manage a technology (include to digitlize design, treatment, analysis and the information management in production process, namely the CAD/CAE/CAM/DNC technology of the mould) it is the accepted raises level of mould industry whole effective technology measure on international, can raise a mould to produce efficiency and product quality greatly, promote the integrated level of the enterprise and benefit. Mould digitlization design and the crucial technology in making develop quickly as what digitlize a technology and gain ground, digitlization had used the whole process that the mould makes. By the graph 1 analysis is informed, mould digitlization technology is a when restrict punch mould development main factor. The digitlization technology of the mould, it is computer technology or computer the application in assisting a technology to design production process in the mould. Summary provides company application computer domestic and internationally to assist successful experience of the technology to tool set, make circuit according to punch mould, technology of digitlization punch mould basically is reflected in 4 respects. The application of technology of CAE of 1 punch figuration in products plan synchronous project is synchronous craft of the punch in development is perforative the whole process at new product, from the technology that understands a product, to the punch analysis for technological efficiency of the product, need the whole journey of punch technologist to participate in to the development of the mould again. Punch CAE technology is from the actual physics of process of strike out form the rule sets out, mould of report of bona fide of computer of have the aid of and the interaction relation of board makings reach board makings actual metabolic whole process. As nonlinear academic, finite the rapid development of yuan of method and computer hardware, the CAE of process of figuration of board makings punch analyses a technology to had entered industry to use level through long-term development, formed a few general or appropriative software, wait like AutoForm/PAM-STAMP. These software provide the following analysis and imitate result: The change of the flow of material, ply, destroy, corrugate, spring back, and leftover stress and meet an emergency. Use CAE technology to be able to make pattern company right in product idea design phase the figuration sex of each spare parts, craft sex offers the product rapid, accurate foreknow. Put forward to evaluate an opinion to the appearance of the spare parts inside cutty time, give out the analytic report of accurate full and accurate, include digital-to-analogue to revise basis, modification method and the influence to follow-up working procedure, the basis that as the structure design branch undertakes improvement to the product or plan determines [1] . 2 be based on modular fast design system to punch mould, what structural design often occupied design workload is very big one part. As the rapid development of computer technology, CAD/CAE/CAM unifinication technology got applied extensively. And the application of technology of punch mould CAD in home, still stay in support mould to design the experience of personnel, alternant plot and formative administrative levels make go up on system of general CAD software, cannot discover the flaw in designing a process in time thereby, the design that extended a pattern is periodic, going up to also affect design quality somehow. Be based on a series of computers such as UG/PROE to digitlize modelling software to make the parameter of the mould changes module design to let " the mould is designed quickly " become a possibility. Want to undertake the parameter of the mould changes module design, standard component library and pattern plate are a foundation. Pass software, guide pillar, guide plate, will strong first class a series of put in storage of standard component statistic, so that be called when the design; In the meantime, written guarantee its corresponding mould compose parameter is changed according to different spare parts make pattern plate, enter structural library likewise. After taking a mould to design the job, predigest task asks (manufacturer home requirement, punch requirement) ; Combine the spot to produce experience actually next, call mould structure library, make be designed first; Undertake modular face is designed again, reentry calls standard component library all right, assemble standard component; Close finally fit a whole pattern [2] . Change module to design implementation to typical structure pattern plate is changed and repeat working intelligence to change through parameter. (1) typical structure pattern plate is changed. Be based on the mind that pattern plate changes, punch pattern all sorts of typical structures have classified summing up, extraction can realize parameter to spend the part of control among them, generate intelligence to change pattern plate to give in the process building a model of whole design application. (2) repeat working intelligence to change. Make the serious go back to work in designing a process, shorten through be record in intelligence to change pattern plate and 2 development tool to achieve the purpose that designs cycle. 3 parameter change Cheng to make up the high speed that realizes a mould to machine what make rhythm as the mould to accelerate, CNC Machining already by pure model face treatment develops model the comprehensive treatment of face and structural range, by in development of low speed treatment is machined to high speed. Application of high speed processing technique basically is like next advantages in mould manufacturing industry: (1) small cut deep, tall feed; (2) improve workpiece to machine exterior quality, reduce burnish; (3) precision rises, reduce workload trying a model; (4) use penknife provides treatment mould detail, reduce cutting tool norms. Reduce use cost; (5) finish with the means of high accuracy, big feed quench the finish machining of steel, and achieve very high mould surface quality, can reduce conventional treatment to cause a mould to be out of shape because of quenching again after finish machining, replace certain technology thereby. Mould of processing technique application makes high speed basically involve machine tool, cutting tool and numerical control process designing 3 respects, specific work flow is shown 2 times like the graph. Want to realize mould safety, efficient treatment, safer contrail taking a knife and sound treatment strategy appear particularly important. Press use cutting tool and machine tool facility library of cutting tool of objective dimension make it and machine tool library, become the technical requirement enumerate of different spare parts the library again (spare parts library) , the digital parameter of 3 libraries is worth CAM of the make it in arranging conformity to write software to Cheng to machine pattern plate, numerical control Cheng is made up meet safer, fast. General component is the outfit recipe law that 4 digitlization assemble a technology to debug medium applied mould in the mould 4 kinds: Crossing-over assembles law, cent to assemble match law, fitting assembly method and attune to get ready match a law. The earliest, the mould is machined in machining center hind, the assembly of the spot uses more assemble a law in group: The worker consults spare parts of guide plate of guide pillar of essence of life undertakes assembly drawing of 2D spare parts directly classification, have a model next by what guide pillar installs after installing guide plate first early or late orderly the assembly of other part, precision work has directly after been assemble, there also are pair of sheets after finish machining the guide pillar precision of condition / guide sliding surface position is spent did not have effective contrast and examination, such, in sheet after finish machining is over, fluctuation model combine a model, the lower mould on discovery oriented error is very big, bring about guide pillar guide plate to be pulled, standard component attaint. Now, mould sheet after having precision work online measure (OMV) measure an outcome (than as above model guide pillar is oriented data and lower mould guide pillar is oriented data) record and statistic have inside software, undertake contrast, discover out of tolerance undertakes changing immediately. Graph 3 build for engine of some project engine inside board press standard of the fluctuation that extend a pattern after treatment is over survey error distributinging plan. According to such measurement the result can is opposite fluctuation model the error is bigger before combining a model area undertakes rectifying and reform, assure oriented clearance, make sure the mould combines modular quality. Nextpage is current, the mould of home of United States of a few Europe is made can use fitting assembly method directly (the method that repairs the quantity of obligate make repairs and supply replacements that goes appointing a spare parts to go up to assemble precision in order to achieve when assemble, call way of make repairs and supply replacements) the assembly that has a pattern. They are passed measure data, the means that deserve to wear guide plate directly or assembles quality undertakes the model is assembled closing. This kind of method increased the rate of progress planned speed combining a model of the mould, be follow-up mould debug won cycle. It is a basis in order to measure data, application software undertakes analytic handling, the means of this kind of fitting assembly method should be met the tendency that after becoming, the mould develops. The application that system of informatization of punch pattern company digitlizes a technology to make a trade in punch mould is wider and wider, it is market government, design, analysis, make, detect the integrated application technology that waits for a mould to make each link unifinication inside whole lifecycle, want to manage each link effectively, need to rely on enterprise informatization construction. The application of enterprise informatization can be generalized simply for 2 respects, namely technical management informatization and manufacturing management informatization. What technical management informatization points to is the application of the CAD/CAE/CAM technology that is based on PDM/CAPP, implementation mould design, production copy true informatization or digitlization; Manufacturing management informatization is a delegate with ERP/MES system, the foundation that the informatization of technical management is manufacturing management informatization [3] (graph 4) . Optimize a product to develop mode and technological process through this system framework, the centralized management that realizes product data and share, design knowledge and treatment technology knowledge accumulate and put sb in a very important position; Build with the workshop exercise attempers for core, the manufacturing process system that gathers information of the plan in producing a course, quality, stock in real time. Adopt systematic measure, swim pattern company up and down business course, technology communication process and business of pattern company interior run a course, with the form of informatization solid comes down surely, thereby sufficient tapping the potentiality of enterprise, answer ability what use efficiency and company what raise company natural resources quickly, final the administrator pattern company is put from the solution in the general affairs of loaded down with trivial details. 1 build the product data set that is a center with mould structure to knit mode, maintain product data consistency to use PDM/CAPP to manage the of all kinds record of all moulds, build the BOM structure of of all kinds mould in the system, at the same time the of all kinds file related to mould spare parts, three-dimensional model, check has assignment certificate of the digital-to-analogue that comes over like leader plant, design, pattern data, change sheet to wait to rise with product structure correlation. Design engineer can pass an input the technical data that the step such as name of part drawing date, spare parts will come inquire place needs, also can get product data through chasing a layer to develop product structure, in inquiring a process design engineer need not know the physical place that documentation deposits, requires product documentation can be searched inside short time. Use PDM/CAPP system, all mould design data centralized management is in structured database, the system will maintain mould data synchronism automatically, assured the uniqueness of mould data and seasonable sex. Design engineer and downstream and other department can get newest mould data and historical record at any time through PDM/CAPP system, can assure consistency of data. 2 build collect the project management platform that is core with control with project plan, optimize a workshop to attemper the workshop government that runs pattern company is one catastrophe problem, manufacturing management is the typical project that implements according to single order, every pay a mould from accept the order, the design arrives production, debug reflect its independent character, need special project controller to make entering spending collection manage with control. Because every project is included a few even about a hundred mould, every mould needs the time of a few months, need at the same time monitoring is designed ten times, make and consign node, the plan of mould project is collected and managing is a complex and trival job. Use ERP/MES system, implementation has order government on unified platform (business is typed) , plan platoon is produced, stock dogs, production attempers the means that waits for a function, through running a system with what plan a layer (ERP) with control system (MES) compositive, plan, production and control close connection rises, established a communication bridge and tie between plan layer and control layer thereby. Plan mould project every medium node, collect as data with pilot node, realize what the workshop manages to optimize attemper. The 3 knowledge that build based database run a system, sharing trade of mould of intellectual inheritance punch is very depend on " experience " industry, abroad each are big the company forms the mould design that has his, technological process and manufacturing parameter database. Through building a part the design of whole pattern, craft is mixed those who make the CAD of can mutual butt joint, CAPP and CAM system is compositive change platform, form a centralized data management system, the punch craft that runs a company effectively and structural design library, typical craft library and tone we should like to ask inscribe the information such as the record, accumulate a mould to develop experience, achieve enterprise intelligence capital fund accumulate. 4 build an electron to change technological process, those who realize a process but the electron that date from sex builds relevant documentation in PDM/CAPP system is examined and approve / extend flow model, all electronic documentation that are examined and approve vote automatically according to examining and approve in flow regulation has flow, flow will examine and approve the task automatically to distribute relevant personnel. Participate in different the examination that examines and approve link undertakes voting in the technological process that personnel can change in the electron, if agree, object or waive the right, be determined of importable watch sees. Systematic general record is whole the information that examines and approve a process, examine and approve the documentation that the documentation that pass will turn into automatically to extend formally, realize a process thereby but date from sex. The place on last word put together is narrated, the punch pattern company of our country has begun will advanced digitlization technology to apply at the mould make in, and development is rapid in last few years, partial enterprise has begun to carry on to Euramerican market order. But, digitlize a technology gain ground to still remain in our country thorough, our punch mould industry develops a standard, especially complex, large in high-grade punch mould and developed country photograph have very big difference than returning. Ought to begin a mould to digitlize design and the research of production technology energetically, make digitlize a technology to apply generally at mould industry, use the mould industry that transforms a tradition, the hasten of general trends place that this is development of industry of our country mould.
