冲压模具外文翻译

Punching die has been widely used in industrial production.In the traditional industrial production,the worker work very hard,and there are too much work,so the efficiency is low.With the development of the science and technology nowadays,the use of punching die in the industial production gain more attention, and be used in the industrial production more and more.Self-acting feed technology of punching die is also used in production, punching die could increase the efficience of production and could alleviate the work burden，so it has significant meaning in technologic progress and economic value. The article mainly discussed the classification,feature and the developmental direction of the pnnching technology. Elaborated the punching components formation principle, the basic dies structure and the rate process and the principle of design; and designed some conventional punching die:the die for big diameter three direction pipe which solved the problom of traditional machining,the drawing and punching compound die with float punch-matrix,the drawing and cutting compound dies with unaltered press,the compound die for the back bowl of the noise keeper,the design of the compound die which could produce two workpieces in one punching,the bending die for the ring shape part ,the bending die which used the gemel ,automate loading die for cutting, the drawing,punching and burring compound dies with sliding automated loading,the punching die for the long pipe with two row of hole,the drawing die for the square box shape workpiece and the burring die for the box shape workpiece.The punching dies that utilized the feature of the normal punch shaped the workpiece in the room temperature,and its efficiency and economic situation is excellent. The dies here discussed can be easily made,conveniently used, and safely operated.And it could be used as the reference in the large scale production of similar workpieces.CAD and CAM are widely applied in mould design and mould making. CAD allows you to draw a model on screen, then view it from every angle using 3-D animation and, finally, to test it by introducing various parameters into the digital simulation models(pressure, temperature, impact, etc.) CAM, on the other hand, allows you to control the manufacturing quality. The advantages of these computer technologies are legion: shorter design times(modifications can be made at the speed of the computer),lower cost, faster manufacturing, etc. This new approach also allows shorter production runs, and to make last-minute changes to the mould for a particular part. Finally, also, these new processes can be used to make complex parts. Computer-Aided Design(CAD)of Mould Traditionally, the creation of drawings of mould tools has been a time-consuming task that is not part of the creative process. Drawings are an organizational necessity rather than a desired part of the process. Computer-Aided Design(CAD) means using the computer and peripheral devices to simplify and enhance the design process .CAD systems offer an efficient means of design, and can be used to create inspection programs when used in conjunction with coordinate measuring machines and other inspection equipment.CAD data also can play a critical role in selecting process sequence. A CAD system consists of three basic components: hardware, software, users. The hardware components of a typical CAD system include a processor, a system display, a keyboard, a digitizer, and a plotter. The software component of a CAD system consists of the programs which allow it to perform design and drafting functions. The user is the tool designer who uses the hardware and software to perform the design process. Based on the 3-D data of the product, the core and cavity have to be designed first. Usually the designer begins with a preliminary part design, which means the work around the core and the cavity could change. Modern CAD systems can support this with calculating a split line for a defined draft direction, splitting the part in the core and cavity side and generating the run-off or shut-off surfaces. After the calculation of the optimal draft of the part, the position and direction of the cavity, slides and inserts have to be defined .Then in the conceptual stage, the positions and the geometry of the mould components-such as slides, ejection system, etc.-are roughly defined. With this information, the size and thickness of the plates can be defined and the corresponding standard mould can be chosen from the standard catalog. If no standard mould fits these needs, the standard mould that comes nearest to the requirements is chosen and changed accordingly-by adjusting the constraints and parameters so that any number of plates with any size can be used in the mould. Detailing the functional components and adding the standard components complete the mould(Fig.23.1).This all happens in 3-D. Moreover, the mould system provides functions for the checking, modifying and detailing of the part .Already in this early stage, drawings and bill of materials can be created automatically. Through the use of 3-D and the intelligence of the mould design system, typical 2-D mistakes-such as a collision between cooling and components/cavities or the wrong position of a hole-can be eliminated at the beginning. At any stage a bill of materials and drawings can be created-allowing the material to be ordered on time and always having an actual document to discuss with the customer or a bid for a mould base manufacturer. The use of a special 3-D mould design system can shorten development cycles, improve mould quality, enhance teamwork and free the designer from tedious routine work. The economical success, however, is highly dependent upon the organization of the workflow. The development cycles can be shortened only when organizational and personnel measures are taken. The part design, mould design, electric design and mould manufacturing departments have no consistently work together in a tight relationship. Computer-Aided Manufacturing(CAM)of Mould One way to reduce the cost of manufacturing and reduce lead-time is by setting up a manufacturing system that uses equipment and personnel to their fullest potential. The foundation for this type of manufacturing system is the use of CAD data to help in making key process decisions that ultimately improve machining precision and reduce non-productive time. This is called as computer -aided manufacturing (CAM).The objective of CAM is to produce, if possible, sections of a mould without intermediate steps by initiating machining operations from the computer workstation. With a good CAM system , automation does not just occur within individual features. Automation of machining processes also occurs between all of the features that make up a part, resulting in tool-path optimization. As you create features ,the CAM system constructs a process plan for you .Operations are ordered based on a system analysis to reduce tool changes and the number of tools used. On the CAM side, the trend is toward newer technologies and processes such as milling to support the manufacturing of high-precision injection moulds with 3-D structures and high surface qualities. CAM software will continue to add to the depth and breadth of the machining intelligence inherent in the software until the CNC programming process becomes completely automatic. This is especially true for advanced multifunction machine tools that require a more flexible combination of machining operations. CAM software will continue to automate more and more of manufacturings redundant work that can be handled faster and more accurately by computers , while retaining the control that machinists need. With the emphasis in the mould making industry today on producing moulds in the most efficient manner while still maintaining quality, moludmakers need to keep up with the latest software technologies-packages that will allow them to program and cut complex moulds quickly so that mould production time can be reduced. In a nutshell, the industry is moving toward improving the quality of data exchange between CAD and CAM as well as CAM to the CNC, and CAM software is becoming more intelligent as it relates to machining processes_resulting in reduction in both cycle time and overall machining time. Five-axis machining also is emerging as a must-have on the shop floor-especially when dealing with deep cavities.And with the introduction of electronic data processing(EDP)into the mould making industry, new opportunities have arisen in mould-making to shorten production time, improve cost efficiencies and higher quality.冲压模具已广泛应用于工业，在传统的工业生产，工人工作很辛苦，有太多的工作，所以效率是很低.在科学和技术的今天，使用的冲压模具开发在实业生产获得更多的关注，并在工业生产中越来越被关注.冲压模具用饲料技术也可用于生产，冲压模具可提高生产的有效性，可以减轻工作负担，因此在科技进步和经济价值具有重要意义。 本文主要讨论了分类，特征以及技术的发展方向。阐述了冲压零件的形成原理，基本结构和死亡过程的速度和设计的原则，设计了一些传统的冲压模具：对大直径管这三个方向解决了传统的机械加工，拉丝模及冲压模具复合使用打孔矩阵，绘图和切割复合冲压模与不变，复合模噪声的门将回碗，复合模具设计，可产生一冲，为两个环形工件弯曲模的一部分，它使用的弯曲模铰链，自动加载成形模具进行切割，绘图，冲压，翻边复合滑动自动化装车模具，冲压模具为两排孔长管，拉丝模框形状为正方形工件为箱形.冲压翻边模具模具是利用了形，在正常室温冲压工件的特点，其效率和经济形势一片大好。 这里讨论的模具可以轻松完成，方便使用和安全分离.它可以作为类似工件的大规模生产提供参考。 CAD和CAM的广泛应用在模具设计和模具制造。民航处让您在屏幕上画一个模型，然后查看从每使用3 - D动画，最后以测试引入数字仿真模型（压力，温度，影响等）CAM技术，对各种参数，它的角度审视另一方面，可以控制生产质量。这些计算机技术的优势是多方面的：更短的设计时间（修改可以在计算机的速度制造），降低成本，更快的制造等这种新方法还可以缩短生产运行，并作出最后一分钟改变为特定的部分模具。最后，同时，这些新工艺可用于制造复杂的零件。 计算机辅助设计（CAD）模具 传统上，工具，模具图纸创建以来，一直一项费时的任务，是不是创作过程的一部分。图纸是一个组织的必要性，而不是过程所需的部分。 计算机辅助设计（CAD）是指使用电脑及周边设备，以简化和增强的设计过程。CAD系统设计提供了有效手段，可用于创建检查方案一起使用时，用坐标测量机和其他检验设备 。CAD数据也可以在选择过程中发挥关键作用的顺序。 CAD系统包括三个基本组成部分：硬件，软件，用户。一个典型的CAD系统的硬件组成包括一个处理器，系统显示器，键盘，数字化仪，绘图仪和一。一个CAD系统软件组件组成的方案，允许它执行设计和绘图功能。用户是谁使用的工具设计的硬件和软件进行了设计过程。 对产品的3 - D数据为基础，核心和型腔必须首先设计。通常情况下，设计师开始了初步设计的一部分，这意味着围绕核心和腔可以改变的工作。现代CAD系统可以支持计算定义为一本草案的方向分割线，分裂和模腔中的核心部分和发电侧运行关闭或关闭表面。后的部分，位置和方向的最佳腔草案计算，幻灯片和插入定义，则必须在概念阶段，位置和几何形状的模具组件-。如滑梯，弹射系统等-是一个粗略的定义。有了这个信息，大小和可以定义板块和相应的标准模具厚度可以选择从标准目录。如果不符合这些标准的模具需求，模具标准件你最近的选择和改变相应的要求，通过调整约束和参数，使任何与任何大小牌的数目，可在模具中使用-。详细介绍了功能性成分和添加标准组件的完整的模具（Fig.23.1）。这一切都在3 - D发生。此外，模具系统提供了检测功能，修改和细节的部分已经在这个早期阶段。，图纸和材料清单可自动生成。 通过对3 - D使用和模具设计的智能系统，典型的2 - D的错误-如冷却和组件之间/腔或一洞错了位置-碰撞可以消除在开始。在任何阶段的材料和图纸条例草案能创造-让材料可以下令时间，始终有一个实际的文件，讨论与客户或为模架制造商投标。 一个特殊的三维模具设计系统，可缩短开发周期，提高模具质量，增强团队从繁琐的日常工作和自由设计师。经济的成功，但是，是高度依赖工作流的组织而定。开发周期可缩短只有在组织人事采取措施。零件设计，模具设计，电气设计和模具制造部门一直没有一起在紧张的关系。 计算机辅助制造（CAM）的模具 一种方法，以减少生产成本，缩短交货时间是由设立生产系统，采用的设备和人员的最大潜能。此类型的制造系统的基础是利用CAD数据，以帮助作出决定的关键工序，最终提高加工精度，减少非生产时间。这就是所谓的电脑辅助制造（CAM）。CAM的目的是对生产，如果可能的话，没有中间步骤，由计算机工作站启动从一个模具加工操作的部分。 凭借良好的CAM系统，自动化并不仅仅发生在个别功能。自动化的加工流程也发生之间的特征，构成了一个部分的，在刀具路径的优化结果。当您创建的特点，构建了CAM系统在处理计划。行动是有序的系统上的分析，以减少刀具的变化和所用的工具的数量为基础。 在CAM方面，趋势是如铣床，支持3 - D结构和高表面质量的高精密注塑模具制造对新技术和工艺。 CAM软件将继续增加的深度和加工情报软件固有的广度，直到数控编程过程变得完全自动化。这是特别先进的多功能机床所要求的加工操作更灵活的组合如此。 CAM软件将继续越来越多的自动化生产的多余的工作，可以由计算机处理速度更快，更准确地多，同时保留了控制机械师的需要。 随着模具制造行业的重点生产模具的最有效的方式，同时保持品质的今日，需要跟上最新的软件技术，封装，使它们的方案，减少复杂模具快速模具生产时间，使可以减少。概括地说，这个行业正朝着提高数据的CAD和CAM以及CAM的数控交流的质量，和CAM软件正变得更“聪明”，因为它涉及到机械加工，导致在这两个周期的时间和减少总的加工时间。五轴加工也正在成为一个“必须拥有”的车间，特别是在处理与深洞。 而随着电子数据处理（EDP）到模具制造行业介绍，新的机会已经出现 在模具制作，以缩短生产时间，提高成本效率和质量更高。朗读显示对应的拉丁字符的拼音字典 - 查看字典详细内容
