Heat Treatment of Die and Mould Oriented Concurrent Design

Abstract:

Many disadvantages exist in the traditional die design method which belongs to serial pattern. It is well known that heat treatment is highly important to the dies. A new idea of concurrent design for heat treatment process of die and mould was developed in order to overcome the existent shortcomings of heat treatment process. Heat treatment CAD/CAE was integrated with concurrent circumstance and the relevant model was built. These investigations can remarkably improve efficiency, reduce cost and ensure quality of R and D for products.

Key words :die design; heat treatment; mould

ong desires for precision,service life,development period and cost,modern die and mould should be designed and manufactured perfectly.Therefore more and more advanced technologies and innovations have been applied,for example,concurrent engineering,agile manufacturing virtual manufacturing,collaborative design,etc.

Heat treatment of die and mould is as important as design,manufacture and assembly because it has a vital effect on manufacture，assembly and service life．Design and manufacture of die and mould have progressed rapidly，but heat treatment lagged seriously behind them．As die and mould industry develops，heat treatment must ensure die and mould there are good

state of manufacture，assembly and wear—resistant properties by request. Impertinent heat treatment can influence die and mould manufacturing such as over—hard and—soft and assembly．Traditionally the heat treatment process was made out according to the methods and properties brought forward by designer．This could make the designers of die and mould and heat treatment diverge from each other，for the designers of die and mould could not fully realize heat treatment process and materials properties，and contrarily the designers rarely understood the service environment and designing thought. These divergences will impact the progress of die and mould to a great extent. Accordingly，if the process design of heat treatment is considered in the early designing stage，the aims of shortening development period，reducing cost and stabilizing quality will be achieved and the sublimation of development pattern from serial to concurrent will be realized．

Concurrent engineering takes computer integration system as a carrier,at the very start subsequent each stage and factors have been considered such as manufacturing，heat treating，properties and so forth in order to avoid the error．The concurrent pattern has dismissed the defect of serial pattern,which bring about a revolution against serial pattern．

In the present work．the heat treatment was integrated into the concurrent circumstance of the die and mould development，and the systemic and profound research was performed．

1 Heat Treatment Under Concurrent Circumstance

The concurrent pattern differs ultimately from the serial pattern(see Fig．1).With regard to serial pattern，the designers mostly consider the structure and function of die and mould，yet hardly consider the consequent process，so that the former mistakes are easily spread backwards．Meanwhile，the design department rarely communicates with the assembling，cost accounting and sales departments．These problems certainly will influence the development progress of die and mould and the market foreground．Whereas in the concurrent pattern，the relations among departments are close，the related departments all take part in the development progress of die and mould and have close intercommunion with purchasers．This is propitious to elimination

of the conflicts between departments，increase the efficiency and reduce the cost．

Heat treatment process in the concurrent circumstance is made out not after blueprint and workpiece taken but during die an d mould designing．In this way，it is favorable to optimizing the heat treatment process and making full use of the potential of the materials．

2 Integration of Heat Treatment CAD／CAE for Die and Mould

It can be seen from Fig．2 that the process design and simulation of heat treatment are the core of integration frame．After information input via product design module and heat treatment process generated via heat treatment CAD and heat treatment CAE module will automatically divide the mesh for parts drawing，simulation temperature field microstructure analysis after heat—treatment and the defect of possible emerging (such as overheat,over burning)，and then the heat treatment process is judged if the optimization is made according to the result reappeared by stereoscopic vision

technology．Moreover tool and clamping apparatus CAD and CAM are integrated into this system．

The concurrent engineering based integration frame can share information with other branch．That makes for optimizing the heat treatment process and ensuring the process sound．

2.1 3-D model and stereoscopic vision technology for heat treatment

The problems about materials，structure and size for die and mould can be discovered as soon as possible by 3-D model for heat treatment based on the shape of die and mould．Modeling heating condition and phase transformation condition for die and mould during heat treatment are workable，because it has been broken through for the calculation of phase transformation thermodynamics，phase transformation kinetics，phase stress,thermal stress，heat transfer，hydrokinetics etc．For example，3-D heat —conducting algorithm models for local heating complicated impression and

asymmetric die and mould，and M ARC software models for microstructure transformation was used．Computer can present the informations of temperature，microstructure and stress at arbitrary time and display the entire transformation procedure in the form of 3-D by coupling temperature field,microstructure field and stress field．If the property can be coupled,various partial properties can be predicted by computer．

2.2 Heat treatment process design

Due to the special requests for strength，hardness，surface roughness and distortion during heat treatment for die and mould，the parameters including quenching medium type，quenching temperature and tempering temperature and time，must be properly selected，and whether using surface quenching or chemical heat treatment the parameters must be rightly determined．It is difficult to determine the parameters by computer fully．Since computer technology develops quickly in recent decades,the difficulty with large—scale calculation has been overcome．By simulating and weighing the property，the cost and the required period after heat treatment．it is not difficult to optimize the heat treatment process．

2.3 Data base for heat treatment

A heat treatment database is described in Fig．3．The database is the foundation of making out heat treatment process．Generally，heat treatment database is divided into materials database and process database．It is an inexorable trend to predict the property by materials and process．Although it is difficult to establish a property database，it is necessary to establish the database by a series of tests．The materials database includes steel grades,chemical compositions，properties and home and abroad grades parallel tables．The process database includes heat treatment criterions，classes，heat preservation time and cooling velocity．Based on the database，heat treatment process can be created by inferring from rules．

2.4 Tool and equipment for heat treatment

After heat treatment process is determined，tool and equipment CAD／CAE system transfers the information about design and manufacture to the numerical control device．Through rapid tooling prototype，the reliability of tool and the clamping apparatus can be judged．The whole procedure is transferred by network，in which there is no man—made interference．

3 Key Technique

3.1 Coupling of temperature，microstructure，stress and property

Heat treatment procedure is a procedure of temperature-microstructure—stress interaction．The three factors can all influence the property (see Fig．4)．During heating and cooling，hot stress and transformation will come into being when microstructure changes.Transformation temperature-microstructure and temperature—microstructure—and stress-property interact on each other．Research on the interaction of the four factors has been greatly developed,but the universal mathematic model has not been built．Many models fit the test nicely，but they cannot be put into practice．Difficulties with most of models are solved in analytic solution，and numerical method is employed so that the inaccuracy of calculation exists．

Even so，comparing experience method with qualitative analysis，heat treatment simulation by computer makes great progress．

3.2 Establishment and integration of models

The development procedure for die and mould involves design,manufacture，heat treatment，assembly，maintenance and so on．They should have own database and mode1．They are in series with each other by the entity—relation model．Through establishing and employing dynamic inference mechanism ，the aim of optimizing design can be achieved．The relation between product model and other models was built．The product model will change in case the cell model changes．In fact，it belongs to the relation of data with die and mould．After heat treatment model is integrated into the system，it is no more an isolated unit but a member which is close to other models in the system．After searching，calculating and reasoning from the heat treatment database,procedure for heat treatment，which is restricted by geometric model,manufacture model for die and mould and by cost and property，is obtained．If the restriction is disobeyed，the system will send out the interpretative warning．

All design cells are connected by communication network．

3.3 Management and harmony among members

The complexity of die and mould requires closely cooperating among item groups．Because each member is short of global consideration for die and mould development，they need to be managed and harmonized．Firstly,each item group should define its own control condition and resource requested,and learn of the request of up-and-down working procedure in order to avoid conflict．Secondly，development plan should be made out and monitor mechanism should be established．The obstruction can be duly excluded in case the development is hindered．

Agile management and harmony redound to communicating information，increasing efficiency，and reducing redundancy．Meanwhile it is beneficial for exciting creativity，clearing conflict and making the best of resource．

4 Conclusions

(1) Heat treatment CAD／CAE has been integrated into concurrent design for die and mould and heat treatment is graphed,which can increase efficiency，easily discover problems and clear conflicts．

(2) Die and mould development is performed on the same platform．When the heat treatment process is made out，designers can obtain correlative information and transfer self-information to other design departments on the platform．

(3) Making out correct development schedule and adjusting it in time can enormously shorten the development period and reduce cost．

模具热处理及其导向平行设计

摘要：

在一系列方式中，传统模具设计方法存在许多缺点。众所周知,热处理对模具起着非常重要的作用。为了克服模具热处理工艺存在的缺点，一种新的模具热处理工艺并行设计方法已经被开发出来了。

热处理CAD/CAE技术是集成了并行环境和有关模型而建立的。这些调查研究可以显著提高效率，降低成本，并保证产品质量达到R和D级。

关键词：模具设计；热处理；模具

传统模具设计主要是依照自身实践经验或依照部分实践经验，而不是制造工艺。在设计完成之前，模具方案通常要被一次又一次的改进，于是有些缺点便出现，例如开发时期长，成本高和实际效果不明显。由于对精确性、使用寿命、开发期和费用的严格要求，先进的模具要求设计和制造得十分完善。因此越来越先进的技术和创新方法被应用其中，例如并行工程、敏捷制造业、虚拟制造业、协同合作设计等。

模具的热处理与模具设计，制造和装配同样重要。因为它对模具的制造装配和使用寿命又及其重要的影响。模具设计与制造发展十分迅速，但是热处理发展却严重滞后它们。随着模具工业的发展，热处理必须保证模具有良好的制造装配和磨损耐热性能。不切实际的热处理将导致模具材料过硬或过软，同时影响模具装配性能。传统的热处理工艺是按照设计师提出的方法和特性制作出来的。这样会使模具设计师和热处理工艺师意见产生分歧，而模具设计师却不能充分地了解热处理工艺和材料的性能，相反热处理工艺师却很少了解模具的使用环境和设计思路。这些分歧将在很大程度上影响模具的发展。因此，如果把热处理工艺设计放在设计阶段之前，则缩短开发周期，减少花费和保证质量等目标将会被考虑，而且从串行到并行的发展模式也将会实现。

并行工程是以计算机集成系统作为载体，在开始以后，每个阶段和因素都被看作如制造、热处理、性能等等，以避免出现错误。并行模式已经摒除了串行模式的缺陷，由此带来了一场对串行模式的革命。

在当前的工作中，热处理被集成到了模具开发的并行环境中，同时也正在进行这种系统性和深入性的研究。

1.热处理下的并行环境

并行模式与串行模式存在根本的不同（见图1）。对于串行模式，设计者大多考虑的是模具的结构与功能，但很难考虑相关的工艺，以致前者的错误很容易蔓延到后面。与此同时，设计本门很少与装配，预算会计和销售部门沟通。这些问题当然会影响模具的开发进度和市场前景。然而在并行模式中，不但以上部门关系联系密切，所有参加模具开发的部门都与买家有密切的交流。这有助于协调各部门消除矛盾，提高工作效率，同时降低成本。

Injection Molding The basic concept of injection molding revolves around the ability of a thermoplastic material to be softened by heat and to harden when cooled .In most operations ,granular material (the plastic resin) is fed into one end of the cylinder (usually through a feeding device known as a hopper ),heated, and softened(plasticized or plasticized),forced out the other end of the cylinder, while it is still in the form of a melt, through a nozzle into a relatively cool mold held closed under pressure.Here,the melt cools and hardens until fully set-up. The mold is then opened, the piece ejected, and the sequence repeated. Thus, the significant elements of an injection molding machine become: 1) the way in which the melt is plasticized (softened) and forced into the mold (called the injection unit); 2) the system for opening the mold and closing it under pressure (called the clamping unit);3) the type of mold used;4) the machine controls.

Interaction design Moggridge Bill Interaction design，Page 1-15 USA Art Press, 2008 Interaction design (IxD) is the study of devices with which a user can interact, in particular computer users. The practice typically centers on "embedding information technology into the ambient social complexities of the physical world."[1] It can also apply to other types of non-electronic products and services, and even organizations. Interaction design defines the behavior (the "interaction") of an artifact or system in response to its users. Malcolm McCullough has written, "As a consequence of pervasive computing, interaction design is poised to become one of the main liberal arts of the twenty-first century." Certain basic principles of cognitive psychology provide grounding for interaction design. These include mental models, mapping, interface metaphors, and affordances. Many of these are laid out in Donald Norman's influential book The Psychology of Everyday Things. As technologies are often overly complex for their intended target audience, interaction design aims to minimize the learning curve and to increase accuracy and efficiency of a task without diminishing usefulness. The objective is to reduce frustration and increase user productivity and satisfaction. Interaction design attempts to improve the usability and experience of the product, by first researching and understanding certain users' needs and then designing to meet and exceed them. (Figuring out who needs to use it, and how those people would like to use it.) Only by involving users who will use a product or system on a regular basis will designers be able to properly tailor and maximize usability. Involving real users, designers gain the ability to better understand user goals and experiences. (see also: User-centered design) There are also positive side effects which include enhanced system capability awareness and user ownership. It is important that the user be aware of system capabilities from an early stage so that expectations regarding functionality are both realistic and properly understood. Also, users who have been active participants in a product's development are more likely to feel a sense of ownership, thus increasing overall satisfa. Instructional design is a goal-oriented, user-centric approach to creating training and education software or written materials. Interaction design and instructional design both rely on cognitive psychology theories to focus on how users will interact with software. They both take an in-depth approach to analyzing the user's needs and goals. A needs analysis is often performed in both disciplines. Both, approach the design from the user's perspective. Both, involve gathering feedback from users, and making revisions until the product or service has been found to be effective. (Summative / formative evaluations) In many ways, instructional

拉深是从凸缘型坯料考虑的，即通过模具上冲头的向下作用使材料被水平拉深。一个凸缘板料上的单元体在半径方向上被限定，而板厚保持几乎不变。板料成形的原理如图2所示。 拉延通常是用来描述在板料平面上的两个互相垂直的方向被拉长的板料的单元体的变形原理的术语。拉延的一种特殊形式，可以在大多数成形加工中遇到，即平面张力拉延。在这种情况下，一个板料的单元体仅在一个方向上进行拉延，在拉长的方向上宽度没有发生变化，但是在厚度上有明确的变化，即变薄。 图2 板料成形原理 弯曲时当板料经过冲模，即冲头半径加工成形时所观察到的变形原理，因此在定向的方向上受到改变，这种变形式一个平面张力拉长与收缩的典型实例。 在一个压力机冲程中用于在一块板料上冲出一个或多个孔的一个完整的冲压模具可以归类即制造商标准化为一个单工序冲孔模具，如图3所示。

This study aims to develop a method of controlling costs and time in relation to mold development, and also to improve product design. This investigation comprises two parts: functional-ity coding, and establishing a standard operation procedure, specifically designed for beverage-container injection mold design and manufacturing. First, the injection mold is divided into several modules, each with a specific function. Each module is further divided into several structural units possessing sub-function or sub-sub-function. Next, dimen-sions and specifications of each unit are standardized and a compatible interface is constructed linking relevant units. This work employs a cup-shaped beverage container to experimentally assess the performance of the modular design approach. The experimental results indicate that the modular design approach to manufacturing injection molds shortens development time by 36% and reduces costs by 19 23% compared with the conventional ap-proach.

前言 在目前激烈的市场竞争中，产品投入市场的迟早往往是成败的关键。模具是高质量、高效率的产品生产工具，模具开发周期占整个产品开发周期的主要部分。因此客户对模具开发周期要求越来越短，不少客户把模具的交货期放在第一位置，然后才是质量和价格。因此，如何在保证质量、控制成本的前提下加工模具是值得认真考虑的问题。模具加工工艺是一项先进的制造工艺，已成为重要发展方向，在航空航天、汽车、机械等各行业得到越来越广泛的应用。模具加工技术，可以提高制造业的综合效益和竞争力。研究和建立模具工艺数据库，为生产企业提供迫切需要的高速切削加工数据，对推广高速切削加工技术具有非常重要的意义。本文的主要目标就是构建一个冲压模具工艺过程，将模具制造企业在实际生产中结合刀具、工件、机床与企业自身的实际情况积累得高速切削加工实例、工艺参数和经验等数据有选择地存储到高速切削数据库中，不但可以节省大量的人力、物力、财力，而且可以指导高速加工生产实践，达到提高加工效率，降低刀具费用，获得更高的经济效益。 1.冲压的概念、特点及应用 冲压是利用安装在冲压设备（主要是压力机）上的模具对材料施加压力，使其产生分离或塑性变形，从而获得所需零件（俗称冲压或冲压件）的一种压力加工方法。冲压通常是在常温下对材料进行冷变形加工，且主要采用板料来加工成所需零件，所以也叫冷冲压或板料冲压。冲压是材料压力加工或塑性加工的主要方法之一，隶属于材料成型工程术。 冲压所使用的模具称为冲压模具，简称冲模。冲模是将材料（金属或非金属）批量加工成所需冲件的专用工具。冲模在冲压中至关重要，没有符合要求的冲模，批量冲压生产就难以进行；没有先进的冲模，先进的冲压工艺就无法实现。冲压工艺与模具、冲压设备和冲压材料构成冲压加工的三要素，只有它们相互结合才能得出冲压件。 与机械加工及塑性加工的其它方法相比，冲压加工无论在技术方面还是经济方面都具有许多独特的优点，主要表现如下； (1) 冲压加工的生产效率高，且操作方便，易于实现机械化与自动化。这是

Design Without Designers 网站截图： https://www.sodocs.net/doc/a913997413.html,/baidu?word=%B9%A4%D2%B5%C9%E8%BC%C6%D3%A2%CE%C4%CE%C4%CF%D 7&tn=sogouie_1_dg 原文： Design Without Designers I will always remember my first introduction to the power of good product design. I was newly arrived at Apple, still learning the ways of business, when I was visited by a member of Apple's Industrial Design team. He showed me a foam mockup of a proposed product. "Wow," I said, "I want one! What is it?" That experience brought home the power of design: I was excited and enthusiastic even before I knew what it was. This type of visceral "wow" response requires creative designers. It is subjective, personal. Uh oh, this is not what engineers like to hear. If you can't put a number to it, it's not important. As a result, there is a trend to eliminate designers. Who needs them when we can simply test our way to success? The excitement of powerful, captivating design is defined as irrelevant. Worse, the nature of design is in danger. Don't believe me? Consider Google. In a well-publicized move, a senior designer at Google recently quit, stating that Google had no interest in or understanding of design. Google, it seems, relies primarily upon test results, not human skill or judgment. Want to know whether a design is effective? Try it out. Google can quickly submit samples to millions of people in well-controlled trials, pitting one design against another, selecting the winner based upon number of clicks, or sales, or whatever objective measure they wish. Which color of blue is best? Test. Item placement? Test. Web page layout? Test. This procedure is hardly unique to Google. https://www.sodocs.net/doc/a913997413.html, has long followed this practice. Years ago I was proudly informed that they no longer have debates about which design is best: they simply test them and use the data to decide. And this, of course, is the approach used by the human-centered iterative design approach: prototype, test, revise. Is this the future of design? Certainly there are many who believe so. This is a hot topic on the talk and seminar circuit. After all, the proponents ask reasonably, who could object to making decisions based upon data? Two Types of Innovation: Incremental Improvements and New Concepts In design—and almost all innovation, for that matter—there are at least two distinct forms. One is

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-term has not formed the industry. Straight stabs 0 centuries 80's 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 (individual) the mold enterprise's 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 so 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 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 structure 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 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 higher than the common mold product; The plastic mold and the compression casting mold proportion increases; Specialized mold factory quantity and its productivity increase;
