【正文】 at Treatment of Die and Mould Oriented Concurrent Design LI Xiong,ZHANG Hongbing,RUAN Xue— yu,LUO Zhong— hua,ZHANG Yan 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 overe the existent shortings of heat treatment process. Heat treatment CAD/CAE was integrated with concurre nt 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。 關(guān)鍵詞 ： 模具設(shè)計；熱處理；模具 傳統(tǒng)模具設(shè)計主要是依照自身 實 踐 經(jīng)驗或 依照 部分 實踐 經(jīng)驗，而不是制造工藝。不切實際的熱處理將導致模具材料過硬或過軟，同時影響模具裝配性能。 并行模式與串行模式存在根本的不同（見圖 1）。 CAD/CAE 一體化 從圖 2 中可以看出，熱處理工 藝的設(shè)計與模擬是一體化模式的核心。計算機能夠在任何時間提交溫度，微觀結(jié)構(gòu)和應(yīng)力的信息，并通過連接溫度場微觀結(jié)構(gòu)領(lǐng)域和力場來顯示三維形式的全部改變過程。通過材 料和工藝來預(yù)測特性已成為一種必然的趨勢。 技術(shù) 溫度，微觀結(jié)構(gòu)，應(yīng)力和特性的聯(lián)系 熱處理程序是一個溫度，微觀結(jié)構(gòu)和應(yīng)力互相作用的程序。 模型的建立和融合 在模具的開發(fā)過程中，涉及到設(shè)計、制造、熱處理、裝配、維修等。如果這種限制不服從，系統(tǒng)會發(fā)出解釋性的警告。同時這有利于激發(fā)人的創(chuàng)造力，消除阻礙和制定出最好的方法。 ⑵模型的開發(fā)已在同一個平臺運行。 各部分之間的管理和協(xié)調(diào) 復(fù)雜的模具需要其中各項目組之間密切合作。它們通過事物的內(nèi)在聯(lián)系建立模型，互14 相串聯(lián)起來，盡管建立和運用動態(tài)推理機制，但其目的在于完成優(yōu)化設(shè)計。在加熱和冷卻期間，當微觀結(jié)構(gòu)轉(zhuǎn)變時熱應(yīng)力和相變遲早會出現(xiàn)。材料數(shù)據(jù)庫包括材料牌號、化學成分、性能和國內(nèi)外同級別目錄表。 熱處理工藝設(shè)計 由于對強度和硬度，表面粗糙度和模具熱處理變形的特殊要求，淬火介質(zhì)的種類、淬火溫度、回火溫度和時間等參數(shù)特性必須經(jīng)過適當?shù)倪x擇，以及是否使用表面淬火或化學熱處理，這種特性必須準確的制定下來。而且工具與夾具的CAD 和 CAE 也集成于這種系統(tǒng)中 。與此同時，設(shè)計本門很少與裝配，預(yù)算會計和銷售部門溝通。這樣會使模具設(shè)計師和熱處理工藝師意見產(chǎn)生分歧，而模具設(shè)計師卻不能充分地了解熱處理工藝和材料的性能，相反熱處理工藝師卻很少了解模具的使用環(huán)境和設(shè)計思路。由于對精確性、使用壽命、開發(fā)期和費用的嚴格要求，先進的模具要求 設(shè)計和制造得十分完善。 mould Traditional die and mould design,mainly by experience or semi— experience， is isolated from manufacturing process .Before the design is finalized， the scheme of die and mould is usually modified time and again， thus some disadvantages e into being,such as long development period,high cost and uncertain practical e to strong desires for precision,service life,development period and cost,modern die and mould should be designed and manufactured 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. 1 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
