1、译文一:译文一: 模具的发展趋势模具的发展趋势 1模具CAD/CAE/CAM 正向集成化、三维化、智能化和网络化 方向发展 (1)模具软件功能集成化 模具软件功能的集成化要求软件的功能模块比较齐全, 同时各功能模块采用 同一数据模型, 以实现信息的综合管理与共享, 从而支持模具设计、 制造、 装配、 检验、测试及生产管理的全过程,达到实现最佳效益的目的。如英国 Delcam 公 司的系列化软件就包括了曲面/实体几何造型、复杂形体工程制图、工业设计高 级渲染、塑料模设计专家系统、复杂形体 CAM、艺术造型及雕刻自动编程系统、 逆向工程系统及复杂形体在线测量系统等。集成化程度较高的软件还包括: P

2、ro/ENGINEER、UG 和 CATIA 等。国内有上海交通大学金属塑性成型有限元分 析系统和冲裁模 CAD/CAM 系统;北京北航海尔软件有限公司的 CAXA 系列软 件;吉林金网格模具工程研究中心的冲压模 CAD/CAE/CAM 系统等。 (2)模具设计、分析及制造的三维化 传统的二维模具结构设计已越来越不适应现代化生产和集成化技术要求。 模 具设计、分析、制造的三维化、无纸化要求新一代模具软件以立体的、直观的感 觉来设计模具,所采用的三维数字化模型能方便地用于产品结构的 CAE 分析、 模具可制造性评价和数控加工、成形过程模拟及信息的管理与共享。如 Pro/ENGINEER、UG 和

3、 CATIA 等软件具备参数化、基于特征、全相关等特点, 从而使模具并行工程成为可能。另外,Cimatran 公司的 Moldexpert,Delcam 公 司的 Ps-mold 及日立造船的 Space-E/mold 均是 3D 专业注塑模设计软件,可进行 交互式 3D 型腔、型芯设计、模架配置及典型结构设计。澳大利亚 Moldflow 公 司的三维真实感流动模拟软件 MoldflowAdvisers 已经受到用户广泛的好评和应 用。国内有华中理工大学研制的同类软件HSC3D4.5F 及郑州工业大学的 Z-mold 软件。 面向制造、基于知识的智能化功能是衡量模具软件先进性和实用性的重要 标

4、志之一。如 Cimatron 公司的注塑模专家软件能根据脱模方向自动产生分型线 和分型面,生成与制品相对应的型芯和型腔,实现模架零件的全相关,自动产生 材料明细表和供 NC 加工的钻孔表格,并能进行智能化加工参数设定、加工结果 校验等。 (3)模具软件应用的网络化趋势 随着模具在企业竞争、合作、生产和管理等方面的全球化、国际化,以及计 算机软硬件技术的迅速发展, 网络使得在模具行业应用虚拟设计、敏捷制造技术 既有必要,也有可能。美国在其21 世纪制造企业战略中指出,到2006 年要 实现汽车工业敏捷生产/虚拟工程方案, 使汽车开发周期从40个月缩短到4个月。 2.模具检测、加工设备向精密、高效

5、和多功能方向发展 (1)模具检测设备的日益精密、高效 精密、复杂、大型模具的发展,对检测设备的要求越来越高。现在精密模具 的精度已达 23m,目前国内厂家使用较多的有意大利、美国、日本等国的高 精度三坐标测量机,并具有数字化扫描功能。 如东风汽车模具厂不仅拥有意大利 产 3250mm3250mm 三坐标测量机,还拥有数码摄影光学扫描仪,率先在国内 采用数码摄影、 光学扫描作为空间三维信息的获得手段,从而实现了从测量实物 建立数学模型输出工程图纸模具制造全过程, 成功实现了逆向工程技术的 开发和应用。 这方面的设备还包括: 英国雷尼绍公司第二代高速扫描仪(CYCLON SERIES2)可实现激光

6、测头和接触式测头优势互补,激光扫描精度为 0.05mm,接 触式测头扫描精度达 0.02mm。另外德国 GOM 公司的 ATOS 便携式扫描仪,日 本罗兰公司的PIX-30、 PIX-4台式扫描仪和英国泰勒霍普森公司TALYSCAN150 多传感三维扫描仪分别具有高速化、廉价化和功能复合化等特点。 (2)数控电火花加工机床 日本沙迪克公司采用直线电机伺服驱动的 AQ325L、AQ550LLS-WEDM 具 有驱动反应快、 传动及定位精度高、 热变形小等优点。 瑞士夏米尔公司的 NCEDM 具有 P-E3 自适应控制、PCE 能量控制及自动编程专家系统。另外有些 EDM 还 采用了混粉加工工艺、

7、微精加工脉冲电源及模糊控制(FC)等技术。 (3)高速铣削机床(HSM) 铣削加工是型腔模具加工的重要手段。 而高速铣削具有工件温升低、切削力 小、加工平稳、加工质量好、加工效率高(为普通铣削加工的 510 倍)及可加工 硬材料(60HRC)等诸多优点。因而在模具加工中日益受到重视。瑞士克朗公司 UCP710 型五轴联动加工中心,其机床定位精度可达8m,自制的具有矢量闭环 控制电主轴,最大转速为42000r/min。意大利RAMBAUDI 公司的高速铣床,其 加工范围达 2500mm5000mm1800mm,转速达 20500r/min,切削进给速度达 20m/min。HSM 一般主要用于大、

8、中型模具加工,如汽车覆盖件模具、压铸模、 大型塑料等曲面加工,其曲面加工精度可达 0.01mm。 1 外文原文外文原文: : Die trendDie trend 1mold CAD / CAE / CAM being integrated, three-dimensional, intelligent and network direction (1) mold software features integrated Die software features of integrated software modules required relatively complete, whil
