外文资料Research on Flexible Die Designing System Using ProE Abstract：Die designing is a demanding and hard workTo design a separate die for each product is time consuming and expensive taskThis paper presents an idea of sets of standard reference diesit gives a concept of flexible die designing using a reference standard die designed in a popular commercial CADCAM softwareProEngineerRather than designing a separate die for each part，just update the die design by selecting the die dimensions as requiredThe use of this concept will prove to reduce time and cost of product in manufacturing industry Key words：die；flexible die designing system ；standardization；ProZE；secondary developmentAt present, the industrial developed countries and regions in the mold industry has been gradually standardize and serialization. In China, although the majority die within the enterprises have business standards, but generally not high degree of standardization, standardization of stamping die in the die-limited parts of the parts. To achieve real savings stamping die design time and shorten the processing cycle, cost savings, reduce design and manufacturing staff workload purposes, it needs to develop a flexible stamping die design system. At the same time, stamping die serialization of the scope of standardization and can not be confined to die-part of the fixed panels, boards, the top plate unloading device commonly used components such as stamping or even die structure, we should achieve serialization and standardization.As CAD / CAM technology in the design and manufacture die in the course of extensive application, it should first be standardized stamping die from the CAD system began. Some large-scale commercialization of the CAD / CAM software, such as Pro / E, UG, and so on. Have developed a specialized injection mold design package. And stamping die design for the special software, users need to be developed.l The application tools Pro / E in stamping die design flexibility in the system development Pro / Engineer by the United States has developed a set of PTC CAD / cAM / CAE software. Pro / E using a single database And feature-based, the design parameters of the model, provides users with 1 The development is very convenient for stamping die flexible system of tools juice1.1 Family Table Fanaily Fable known as the Family Table, the structure used to create the same or similar parts of the size and characteristics of the standardized database tables, is devoted to the establishment of a standard parts library tool. The use of the former first family table to create a generic representation of the components (the generic), according to the need to target and then added to the family table a series of management.Family sheet management can be the object of a size (dimension), features (feature), parameters (parameter) and assembly parts (component), and so on.A family table can have multiple levels, that is a generic parts can contain multiple sub-components (instance, also known as examples), and each Instance can contain their own Sub Instance. Discharge screw (stripper-bolt) the family table structure as shown in Figure 1.Figure 1 Family Table hierarchy1.2 RelationsRelations (relations) between mathematics and procedures, including grammar, and its main role is to be part or assembly of the relevance of the data by size symbols, and other parameters of grammar (syntax) to establish mathematical formula to meet the design requirements. Pro / E system of relations can be found in Sketch, Feature, Part and in the Assembly. Simple sentence, judgement and sentence is to establish relations of common format. Simple sentence that a simple mathematical relationship between the size of direct response associated situation. The use of simple format, such as d6 = L. BP 1 2 * d3. Judgement on the sentence for certain occasions, by specifying conditions to express design intent, grammar structure: IF ENDIF or IF ELSE ENDIF in the ELSE ENDIF between conditional statements can be multi-nested. Relations in the standardization and flexible stamping die design system in the building process plays a very important role, it has decided to parts of the geometric shape and characteristics of relations between the digital Xiao, parts relations between the assembly and parts assembly in the presence of middle - A number of features.1.3 ProProgramPro / Program (program) is the Pro / E of a procedural tool, similar to its grammar VBA and Office software in the Macro (Acer). When users use of Pro / engineer to design .The product of various kinds of information to document the format will be recorded. Through the Pro / Progran document editing, can be achieved on the characteristics of the hide, delete and re-order the assembly of components to add and replacement operation. These features stamping dies for the establishment of standard parts library, standards and flexible design structure of the system is very useful.Program files in the structure can be broadly classified into the title, set of parameters relationship, to add features (parts) and updating the quality attributes, such as five parts. In INPUT END INPUT Xiao located between the parameters of the RE1 ATIONS ENDREALATIONS relations between the various add in the ADD END ADD and added features (part module) or parts (assembly module). Pro / Program provides three types of parameters: NUMBER (numerical) STRING (string) and YES-NO (it).2. Standards moldbase of the development2.1 Standards moldbase Classification and organizations Die-stamping die is an important part. The typical model-there are three types: rear-guided-mode (back pillar sets), the middle-guided-mode (center pillar sets) and the guided-mode-angle (diagonal pillarsets). Each type of die-also includes a variety of specifications. According to Die boundary demarcation size, rear-guided, in a L B-22 specifications, D0 specifications 6 (L = B), middle-guided, in the nine-D0 specifications, the guided-mode-Kok L B specifications 7 2-3.In order to facilitate the management and data calls, the standard mode of the directory of the best-established in the Pro / E installation directory. As three categories-the larger structural differences, it may die-the root of the establishment of three other subdirectories, each subdirectory contains all the component parts-mode, and each type of parts can be adopted Pro / E Software for the family table, and tools such as the establishment of standard procedures for the database.2.2 Standards moldbase library buildingDie-stamping die from the main mode on the Block (upper.shoe), nder-Block (1 ower.shoe), I. column (guide.pillar) and I. Case (guidebushing), and other components. In order to make structural integrity of mold, can also die stalk (shank) assembly to die-in. Here are rear-die I.Establishment of the standard method. First of all the various components to create three-dimensional model, and then the standard manual data in the table a series of symbolic dimension added to the group on January 1 Editor (can also use Excel for editing). Add in the size of symbols, Size will be the best symbol to revise the manual and the size of the same symbol. Because people can not distinguish between Table Capitalization is, when both the same size letters, proposed to use capital letters to distinguish between pairs of characters, such as that for the d D, and D that will become a DD.Standard on two-Block: When the L B 200 mm 160 mn-i have installed Boss, and when L B is less than or equal to the scope of non-installation of Boss, shown in Figure 2. Determine whether Boss in two ways: one way is to use Family Table, will generate the Boss Extrude Offset two characteristics and the way to Feature added to the family table, and in these two characteristics of the list Enter in the Y or N, to determine the specifications of a certain mode on the Block, whether these two features; Another method is to find these two features in the Pro / Program in the location and characteristics of the process to add Extrude His statement before the judge IF L 200 1 B 160, adding the Offset characteristics of the procedures used END IF the end of judgement.Figure2. die on the ground in two types2.3 The establishment of Standards moldbase for In Pro / Assembly in the same module can be generated by the use of family die-standard database. Family structure in the assembly, when selected COrnponent, select the mode of all the parts-and enter a different group in the table-model specifications required by the standards of sub-components of the name, as shown in Figure 3. Figure 3 rear-guided, in the standard mode of Family TableCommon mode handles four types: pressure-in-stalk, the flange-stalk, Screw-mode and floating stems die stalk. If the four types of module assembly to handle all the common-mode model (Figure 3 in the assembly only two kinds), in the group table by the need to enter the module handles parts of the name, set the parameters of INPUT, with Regenerate Called when the parameters of renewable order to choose the mode of different types of handles. Of course, people can also die of the table do not have to handle characters with N to curb, as shown in Figure 3-mode system is used in this method.3 The development of standard stamping die 3.1 The typical combination of stamping dieStamping die in the larger structural differences and establish flexible stamping die design systems using the best combination of the typical mold. Use of combinations to determine the structure of the typical mold of the structure, and thus determine the composition of the various components die sizes and assembly relations. Commonly used combination of stamping die typical structure: a fixed combination of unloading, Tanya unloading combinations, composite model portfolio, such as plate-portfolio. Mold can not be separated from the structure of ISO standardization of parts, in the Pro / Engineer Dies in the standardization of parts can be used in the design of the bottom-up approach can also be used top-down design.3.2 die in the process of assembling data transferBecause of complicated, so stamping die by the standardization of the factors to consider-Modulus than standardized by many more factors to consider, one of the most important factor is the size of the correlation between the components. In the mold of a standard combination, assembly and components, parts and components between the need for data transmission, and in the Pro / Assembly can be very easy to achieve this objective.3.2.1 by the assembly of components to the data transferPro / Program can use the assembly EXECUTE statement will be down the parameters in a sub-assembly or parts delivery, the use of syntax is as follows: EXECUTE PART / ASSEMBLY file name components or sub-assembly of the parameters in the assembly of = END EXECUTE EXECUTE statement parameters can not leapfrog data transmission, not by the assembly to sub-assembly of components in the direct transmission of data.3.2.2 data transfer between the componentsWhen added to the assembly of components are in a Id, it can complete the assembly of components between the data transfer. Id assembly of components, can be used in the menu RELATIONs Session Id command to query. Figure 4 is the combination of Tanya discharge standards in the spring of unloading assembly diagram. As assembly to die in the spring have a pre-compression and thus the length of its assembly (Hs) are no longer equal to the length of freedom (H.). In determining H, you can use the following mathematical relationship:Hs:38= L:32一tbp:0 In this way can always guarantee equal to the length of spring assembly from the surface to Dianban discharge board under the surface height, thus eliminating the relevant parts were replaced after the size of Laws. In the design of this mold is very practical, because the mold assembly in a similar situation there are many. Again, in determining the discharge screw on the seat-hole diameter (dI34), they can use the following mathematical relationship：d134:8=D:32+2This Id, established by the mathematical relationship between the need to use Regenerate order to take effect, so different parts on the size of the location of as little as possible in this way, so as not to die in the initial call model will appear at the wrong result will be displayed. But if the parts in between and parameters to transfer data, the location of the various components of size parameters to create a mathematical relationship, the trouble can be avoided.3.2.3 standard replacement partsFamily Table used to establish the standard parts can lookup. inst Replacement statement. Lookup inst allows users to find the standard parts that match the sub-components, if not find the results, then return to a generic 4 J.Lookupinst ： lookup inst(genericname，match-mode，paramnamel，matchvaluel，param-name2， matchvalue2) One match. preferred mode of three, representing different meanings: one is to find parameters of less than or equal to find the value of components; parameter values 0 to find an exact match to find value of the sub-components; to find parameters of greater than or equal to find value The sub-components.3.3 structure of the assemblyDie parts to complete the establishment and rationalize the assembly relations between the components, you can generate mold assembly model. Figure 5 for the development of the author Tanya unloading combination of specifications for the 200 mm 160 mm of die structure (omit all the characteristics of thread).3.4 stamping die callStamping die in the Pro / Assembly call directly, but also can be used Pro / TOOLKIT development of visual user interface to call. Pro / TOOLKIT Pro Ecuador is the second development system software package, its main purpose is to allow users or third parties through the expansion of C code Pro / E function, based on the development of Pro / E system of application modules to meet user Special needs. Pro/T00LKIT use of the UI dialog, the menu VC + + and Visual Interface technology, designed to facilitate flexible and practical stamping die design system for interactive interface. Use interface called the structure of various stamping dies, the choice of different specifications of the parts, enter a different parameters to determine sheet parameters as well as their positioning in the mold, and further in the system design punch, die and other structures, Thus greatly enhance the efficiency of stamping die design.4 ConclusionSince stamping process a wide range of complex processes, and the shape of various parts die, stamping dies in achieving standardization and development of flexible design system and the process is very complicated, but flexible stamping die design system of stamping die CAD is to improve the level of the cornerstones . Pro / E powerful components, the assembly of the criteria for the establishment of the functions of stamping dies for the standardization and flexible design of the feasibility of developing systems to provide a strong guarantee. In the development of flexible design system, should ingenious application of Pro / E software provided by an effective tool, considering the different types of standard structural composition of the assembly relations. Between the parts and components meet requirements of size structure changes, and the best use RELATIONS Pro / Program prepared by the mathematical relations systems and procedures to increase the flexibility and practicality. Die flexible design and application development system to avoid a mold designers unnecessary duplication of labor, so that the programme will focus on the concept, process optimization, and other creative work, thus mold the rapid design and production standards have a practical application Significance.8外文翻译冲压模具柔性设计系统的研究摘要：冲压模具设计是一项十分复杂的工作。根据不同的冲压件 单独设计模具需要很 长时间，模具的制造成本也会大大增加。介绍 了应 用模具设计软件ProEngineer开发 冲压模具柔性设计 系统的具体方法，先建立模具零部件的标准数据库 ，调 用标准零件 生成典型的冲压模具组合。在根据冲压件与工艺需要选取不同规格的模具后 ，只需进行 少量的工作 即可完成整个模具的设计过程。这样将使设计时间缩短、制造成本降低，因而对冲压模具的快速设计与规范生产具有重要的现实意义。 关键词：冲压模具；柔性设计系统；标准化；ProE；二次开发目前，在工业发达的国家和地区，模具工业已逐步实现标准化 和系列化。而在我 国，虽然大部分模具企业也有内部 的企业标准，但是普遍标准化程度 不高，冲压模具的标准化也仅限于模架部分的一些零部件。如果要真正地达到节省冲压模具设计时间 、缩短加工周期 、节约成本、减少设计人员与制造人员工作量的目的，就需要开发出冲压模具的柔性设计系统。同时 ，冲压模具标准化和系列化的范 围 也不能只局限于模架部分 ，对固定板 、垫板 、卸料板 、顶料装置等常用零部件甚至是冲压模具结构，都要实现标准化和系列化1。 由于 CADCAM 技术在模具设 计与制造 过程 中广泛应用，因此标准化首先应该从冲压模具 CAD 系统开始。一些大型的商品化 CADCAM软件，如 ProE、UG等。都已开发出专门的注射模具设计软件包。而用于冲压模具设计的专用软件则有待于用户自行开发 。 1 ProE在冲压模具柔性设计系统开发中的应用工具 ProEngineer是 由美 国 PTC公 司开发的一套 CADcAMCAE软件。ProE采用单一的数据 库以及基于特征的、参数化的设计模式，为用户提供 了十分方便的开发冲压模具柔性设汁系统的工具 1.1 Family Table Fanaily Fable称为族表，用来建立结 构相 同或相近零件的尺寸与特征的标准化数据库表 ，是一 个专门用于建立标准零件库的工具 。使用族表前要先创建具有代表性的通用零件(the generic)，然后根据需要将对象添加到族表中进行系列化管理。可以用族表管理 的对象有尺寸 (dimension)、特征(feature)、参数 (parameter)和装配部 件 (component)等。 一个族表可以有多个层次，即一个通用零件可以包含多个子零件 (instance，又称实例)，而每个Instance又可以包含自己的Sub Instance。卸料螺钉(stripperbolt)的族表结构如图 1所示。.图 1 Family Table的层次结构1.2 Relations Relations(关系 )包括数学关系与程序语 法 ，其主要作用是将零件或装配中具有关联性的数据通过尺寸符号 、参数及其他语 法(syntax)建立数学关系式 ，以满足设计要求。ProE系统 中的关系可存在于 Sketch、Feature、Part及 Assembly中。简单句 和判断句是建立关系的常用格式。简单句表示单纯的数学关系，直接反应尺寸之间的关联情况。其使用格式简单，如 d6=LBP一2*d3。判断句适合于一些特定的场合，通过 指定条件来表达设计意图，语法结构为：“IFENDIF”或“IFELSEENDIF”。在“ELSEENDIF”之间条件语句可以多层嵌套。关系在 冲压模具标准化与柔性设计系统的建立过程 中起着十分重要的作用，它具有决定零件的几何形状以及特征之间的位嚣关系 、部件之间的装配关系以及部件是否存在于装配体中等多项功能。 1.3 ProProgram ProProgram(程序)是 ProE提 供的一 个可程序化的工具 ，其语法类似于 VBA和 Office软件中的Macro(宏 )。 当用 户 运用 ProEngineer进 行 设 计时 ，产品的各种信息 会以文件的格式记 录下来。通过对 ProProgran文件编辑 ，可 以实现对特 征的隐 藏、删除与重新排序、对装配部件的添加和替换等操作。这些功能对于建立冲压模具标准件库、标准结构库和柔性设计系统是非常有用的。程序文件在结构上大致可分为标题 、参数设置、关 系式 、添加特征 (部 件)和更新质量属性等 5个部分 。在“INPUTEND INPUT”之 间进行 设嚣参数
