冷沖連接片級進(jìn)模模具設(shè)計,連接,片級進(jìn)模,模具設(shè)計 湖南理工大學(xué)畢業(yè)生設(shè)計專用 前言 冷沖模是實(shí)現(xiàn)冷沖壓加工的基本工藝裝備，沖壓件的表面質(zhì)量尺寸精度，生產(chǎn)效益均于模具結(jié)構(gòu)及其合理關(guān)系很大，模具的設(shè)計水平直接反映了冷沖壓技術(shù)水平的高低，因此，冷沖模的合理設(shè)計具有重要的意義。 我國在機(jī)械加工行業(yè)比其他發(fā)達(dá)國家落后很多，這不僅僅是技術(shù)上的落后，人才的緊缺也是我國機(jī)械加工行業(yè)的一個難以逾越的瓶頸。所以近年來，國家在機(jī)加工方面不斷加大投入力度，在引進(jìn)一批先進(jìn)技術(shù)的同時，不斷投入人力、物力，以培養(yǎng)最新一代數(shù)控型人才做好堅實(shí)基礎(chǔ)。 而作為我們一個機(jī)械專業(yè)的學(xué)生，怎樣才能設(shè)計一副合格、優(yōu)秀的沖模設(shè)計呢？ 首先，我們的基礎(chǔ)知識一定要扎實(shí)。俗話說，百年基業(yè)，始于基石。沒有了豐富和扎實(shí)的機(jī)加工知識，怎么可以設(shè)計出一副好的模具呢？其次便是要求我們要有嚴(yán)謹(jǐn)?shù)淖鍪略瓌t和認(rèn)真的學(xué)習(xí)態(tài)度，在不斷的錯誤和進(jìn)步中找到最適合自己的設(shè)計要求的方案。最后，我們對自己的設(shè)計要不斷的進(jìn)行檢驗(yàn)，直到合格為止。 目 錄 一、論文－我國機(jī)械制造業(yè)管理信息化特點(diǎn)及發(fā)展趨勢…………（1） 二、工藝分析………………………………………………（13） 三、確定工藝方案…………………………………………（13） 四、工藝與設(shè)計計算………………………………………（14） 五、計算各主要零件的尺寸………………………………（16） 六、受力部件的受力計算與設(shè)計 沖裁力……………………………………………（16） 卸料力……………………………………………（16）推件力……………………………………………（16）頂件力的計算……………………………………（16） 七、壓力中心的確定與計算………………………………（17） 八、排樣圖與搭邊值及條料寬度計算……………………（17） 九、沖模主要零部件的設(shè)計與選用………………………（18） 十、模架及零件……………………………………………（19） 十一、其它支承零件………………………………………（19） 十二、緊固件………………………………………………（20） 十三、繪制模具裝配圖……………………………………（20） 十四、繪制模具工作零件圖………………………………（20） 十五、畢業(yè)設(shè)計心得………………………………………（21） 十六、參考文獻(xiàn)……………………………………………（23） 論文 我國機(jī)械制造業(yè)管理信息化特點(diǎn)及發(fā)展趨勢 1． 前言? 制造業(yè)特別是機(jī)械制造業(yè)是國民經(jīng)濟(jì)的支柱產(chǎn)業(yè)，現(xiàn)代制造業(yè)正在改變著人們的生產(chǎn)方式、生活方式、經(jīng)營管理模式乃至社會的組織結(jié)構(gòu)和文化。由于中國潛在的巨大市場和豐富的勞動力資源，世界的制造業(yè)正在向中國轉(zhuǎn)移，中國正在成為世界的制造大國。我國在家電等若干產(chǎn)品的產(chǎn)量已居世界第一位。但是在自主知識產(chǎn)權(quán)的創(chuàng)新設(shè)計、先進(jìn)制造工藝和裝備及現(xiàn)代化管理等方面仍然存在很大差距，所以我們還不是制造強(qiáng)國。本文僅就機(jī)械制造企業(yè)目前管理中存在的問題、如何利用信息技術(shù)提高管理水平、管理信息化的特點(diǎn)和技術(shù)發(fā)展趨勢作一些研究，供機(jī)械制造企業(yè)制定信息化方案時參考。? 1. forewords The manufacturing industry specially is the mechanical manufacturing industry is the national economy pillar industry, the modern manufacturing industry is changing people's production method, the life style, the management management pattern and even society's organizational structure and the culture. As a result of the Chinese latent giant market and the rich labor force resources, the world manufacturing industry is shifting to China, China is becoming the world the manufacture great nation. Our country and so on certain products output has occupied the first in the world in the electrical appliances. But in independent aspect and so on intellectual property rights innovation design, advanced manufacture craft and equipment and modern management still had the very big disparity, therefore we make the powerful nation. Does this article only at present manage the question on the machine manufacture enterprise which exists, how using the information technology enhancement management level, the management information characteristic and the technological development tendency does some research, formulates when the information plan for the machine manufacture enterprise refers. 2．機(jī)械制造企業(yè)目前管理中存在問題? 中國機(jī)械制造業(yè)經(jīng)過幾十年的努力已經(jīng)具有相當(dāng)?shù)囊?guī)模，積累了大量的技術(shù)和經(jīng)驗(yàn)。但是隨著世界經(jīng)濟(jì)一體化的形成，由于中國潛在的巨大市場和豐富的勞動力資源，國外的技術(shù)、資金、產(chǎn)品大量涌入中國，中國企業(yè)面臨前所未有的國內(nèi)外激烈的競爭局面。競爭要求企業(yè)產(chǎn)品更新?lián)Q代快、產(chǎn)品質(zhì)量高、價格低、交貨及時、服務(wù)好。這些市場競爭的武器與企業(yè)管理的模式、管理方法、管理手段、組織結(jié)構(gòu)、業(yè)務(wù)流程密切相關(guān)。然而中國企業(yè)及人們的思想意識由于受到30-40年計劃經(jīng)濟(jì)的影響，上述競爭武器與發(fā)達(dá)國家相比存在很大差距。? （1）生產(chǎn)計劃控制的模式落后? 尚未實(shí)施ERP的機(jī)械制造企業(yè)幾乎100%采用臺套計劃的方式。即以產(chǎn)品最長生產(chǎn)周期作為構(gòu)成產(chǎn)品各種物料的采購提前期和生產(chǎn)提前期。過分夸大的提前期是造成庫存和在制品儲備高，流動資金占用大的根本原因。生產(chǎn)計劃與采購計劃脫節(jié)，零件成套水平差，不能準(zhǔn)時交貨?；蛘哂酶邇鋪肀＝回浧?。距離現(xiàn)代管理方法物料需求計劃MRP、準(zhǔn)時生產(chǎn)JIT、供應(yīng)商管庫房VMI、同步生產(chǎn)相差甚遠(yuǎn)。? （2）企業(yè)應(yīng)變能力差? 今天的市場瞬息萬變，需求多樣化。按訂單裝配MTO，按訂單制造MTO，按訂單設(shè)計MTD，大規(guī)模定制MC。品種規(guī)格繁多，生產(chǎn)、采購異常復(fù)雜。從客戶—銷售—設(shè)計—生產(chǎn)—采購—財務(wù)—成本，需要一個完整的供應(yīng)鏈管理，才能動態(tài)快速地響應(yīng)客戶需求，適應(yīng)千變?nèi)f化市場和客戶定制化的要求。? （3）成本計算不準(zhǔn)確，成本控制差? 人工成本核算一般只能計算產(chǎn)品成本，無法計算零部件成本。成本費(fèi)用分?jǐn)偤艽郑罅砍杀緮?shù)據(jù)采集是人工歸集的，數(shù)據(jù)準(zhǔn)確性很差，使得成本計算不準(zhǔn)確。一般不進(jìn)行標(biāo)準(zhǔn)成本的計算，也很少進(jìn)行成本分析，因此成本控制差。? （4）信息分散、不及時、不準(zhǔn)確、不共享? 制造業(yè)產(chǎn)、供、銷、人、財、物是一個有機(jī)的整體，他們之間存在大量信息交換。然而人工管理信息分散、缺乏完善的基礎(chǔ)數(shù)據(jù)，信息分散、不及時、不準(zhǔn)確、不共享、大大影響管理決策的科學(xué)性。? （5）科層式的組織機(jī)構(gòu)而不是面向業(yè)務(wù)流程的扁平化的組織，一般業(yè)務(wù)流程不合理，業(yè)務(wù)流程的管理和控制不規(guī)范，隨意性大。? （6）缺乏標(biāo)準(zhǔn)化、規(guī)范化、制度化、程式化的管理，管理的優(yōu)劣因人而異。盡管通過ISO9000制定了一系列的程序文件，執(zhí)行的效果可因企業(yè)和管理者而異。? （7）管理工具落后，大部分企業(yè)仍處于手工分散管理或微機(jī)單項管理的階段。有的企業(yè)也建立了全廠的計算機(jī)網(wǎng)絡(luò)，但應(yīng)用仍是分散的，沒有實(shí)現(xiàn)信息的共享和資源的優(yōu)化配置。? （8）現(xiàn)代化管理的新思想、新方法、新技術(shù)的應(yīng)用差。例如：敏捷制造AM、虛擬制造VM、準(zhǔn)時生產(chǎn)JIT、客戶關(guān)系管理CRM、供應(yīng)鏈管理SCM、商業(yè)智能BI、電子商務(wù)EC、企業(yè)資源計劃ERP等。 ?2. machine manufactures enterprise at present manages has the problem The Chinese mechanical manufacturing industry passed through for several dozens years diligently already to have the suitable scale, accumulated the massive technologies and the experience. But along with the world economics integration formation, as a result of the Chinese latent giant market and the rich labor force resources, the overseas technology, the fund, the product massively wells up into China, the Chinese enterprise faced with the unprecedented domestic and foreign keen competition aspect. The competition request enterprise product renewal quick, the product quality high, the price low, the delivery is prompt, serves. These market competitions weapons and business management pattern, management, management method, organizational structure, service flow close correlation. However Chinese enterprise and people's ideology because receives 30-40 year planned economy the influence, the above competition weapon and the developed country compare the existence very big disparity. (1) productive plan control pattern backwardness not yet implements ERP the machine manufacture enterprise nearly 100% to use the wrap plan the way. Namely proposes the earlier period and the production by the product longest production cycle as the constitution product each kind of material purchase proposes the earlier period. Excessively exaggerating proposes the earlier period is creates the stock and the goods in process stockpiles high, the floating capital takes the big basic reason. The productive plan and purchases the plan to come apart, the components complete set level error, cannot punctually deliver. Or with high stockpiles guarantees the date of delivery. Plans MRP from the modern management material demand, punctually produces JIT, the supplier manages storehouse VMI, the synchronized production is far from. (2) the enterprise strain capacity difference today market is fast changing, demand diversification. Assembles MTO according to the order form, makes MTO according to the order form, designs MTD according to the order form, large-scale has custom-made MC. Variety specification many, the production, the purchase exceptionally is complex. From the customer - sale - design - production - purchase - finance - cost, needs a complete supply chain management, can dynamic fast respond the customer demand, adapts the ever changing market and the customer has custom-made request. (3) cost finding, the cost control difference artificial cost accounting generally only cannot calculate the product cost, is unable to calculate the spare part cost. The cost expense shares very thickly, the massive costs data acquisition is artificially gathers together, the data accuracy is very bad, causes cost finding plate out of true. Generally does not carry on the standard cost the computation, also very little carries on the cost analysis, therefore cost control difference. (4) the information disperses, is inferior to when, does not share the manufacture immovable property, for, sells, the person, the wealth, the thing is an organic whole, between them has the massive exchange of information. When artificially manages the information to disperse, to lack the consummation the foundation data, the information disperses, is inferior to, does not share, the tremendous influence management decision-making scientific nature. (5) the branch level -like organizations and agencies but are not face the service flow the flat organization, the general service flow is unreasonable, the service flow management and the control is not standard, is at will big. (6) lacks standardized, standardized, the institution, the formula management, the management fit and unfit quality is different from person to person. Although has formulated a series of procedures document through ISO9000, the execution effect may because of the enterprise and the superintendent but different. (7) manages the tool to be backward, the majority of enterprises still were in the manual disperser management or the microcomputer single item management stage. Some enterprises have also established the entire factory computer network, but applied was still dispersible, has not realized information sharing and the resources optimized disposition. (8) modern management new thought, new method, new technical application difference. For example: Agilely makes AM, hypothesized makes VM, punctually produces JIT, the customer relations manages CRM, supplies the chain to manage SCM, commercial intelligence BI, electronic commerce EC, the enterprise resources plans ERP and so on. 3．用信息技術(shù)提高機(jī)械制業(yè)管理水平? 上述目前管理中存在的問題嚴(yán)重地影響著企業(yè)管理水平、管理效率和企業(yè)的競爭能力。采用現(xiàn)代化的管理思想、方法和計算機(jī)網(wǎng)絡(luò)通信技術(shù)，實(shí)現(xiàn)機(jī)械制造企業(yè)的管理創(chuàng)新、制度創(chuàng)新和技術(shù)創(chuàng)新是擺在每個企業(yè)面前刻不容緩任務(wù)。所以建立聯(lián)接廠內(nèi)外的計算機(jī)網(wǎng)絡(luò)通信系統(tǒng)，選擇先進(jìn)、成熟、適合企業(yè)管理需求的企業(yè)資源計劃ERP、客戶關(guān)系管理CRM、供應(yīng)鏈管理SCM、商業(yè)智能BI、電子商務(wù)EC等軟件系統(tǒng)，通過管理咨詢和業(yè)務(wù)流程重組，優(yōu)化設(shè)計企業(yè)的組織機(jī)構(gòu)、管理模式、業(yè)務(wù)流程，應(yīng)用上述軟件系統(tǒng)，實(shí)現(xiàn)企業(yè)管理的信息化。以克服目前企業(yè)管理中存在的問題，提高企業(yè)管理水平、管理效率和企業(yè)的競爭能力，是企業(yè)面對知識經(jīng)濟(jì)和全球經(jīng)濟(jì)一體化做出的必然選擇。系統(tǒng)建設(shè)的目標(biāo)是：? （1）建成一個覆蓋全公司的計算機(jī)網(wǎng)絡(luò)化的管理信息系統(tǒng)。該系統(tǒng)使企業(yè)的生產(chǎn)經(jīng)營實(shí)現(xiàn)物流、資金流、信息流和工作流的高度統(tǒng)一與并行運(yùn)作，并通過Intranet、Internet?實(shí)現(xiàn)企業(yè)內(nèi)、外部充分的信息交流及企業(yè)與外界的聯(lián)系，形成有效的敏捷供需鏈系統(tǒng)。? （2）?采用先進(jìn)的生產(chǎn)計劃控制方法。打破臺套計劃的方式，按各種物料的采購提前期和生產(chǎn)提前期編制物料需求計劃。建立一個有效、靈活的由主生產(chǎn)計劃、物料需求計劃和車間作業(yè)計劃的三級計劃所組成的生產(chǎn)計劃管理體系，最大限度的縮短產(chǎn)品生產(chǎn)周期、采購周期、準(zhǔn)時交貨，快速響應(yīng)客戶需求，最大限度的降低庫存和成本，提高售后服務(wù)水平。有條件的企業(yè)推行準(zhǔn)時生產(chǎn)JIT、供應(yīng)商管庫房VMI、同步生產(chǎn)等先進(jìn)管理方法。? （3）實(shí)現(xiàn)全公司基礎(chǔ)數(shù)據(jù)（如物料數(shù)據(jù)、產(chǎn)品結(jié)構(gòu)數(shù)據(jù)、產(chǎn)品設(shè)計工藝數(shù)據(jù)、生產(chǎn)能力數(shù)據(jù)等）統(tǒng)一生成、統(tǒng)一維護(hù)和統(tǒng)一管理，供經(jīng)授權(quán)的各相關(guān)部門使用，真正做到數(shù)出一家、數(shù)據(jù)共享，避免冗余。通過ERP系統(tǒng)的建立和實(shí)施進(jìn)一步理順企業(yè)的管理程序，做到管理的制度化、規(guī)范化和科學(xué)化。? （4）針對目前各管理部門中信息分割的情況，建立以客戶為中心的動態(tài)信息反饋和監(jiān)控體系，實(shí)現(xiàn)對每項任務(wù)從合同簽訂、設(shè)計、生產(chǎn)、采購、成本核算到成品發(fā)貨全過程的動態(tài)跟蹤，使每項任務(wù)處于有效的監(jiān)控之下。? （5）加強(qiáng)財務(wù)管理和健全成本核算功能。真正建立起二級成本核算體系，采用先進(jìn)的成本核算方法，較為準(zhǔn)確地核算出零部件成本和產(chǎn)品成本，為銷售報價和財務(wù)核算提供可靠依據(jù)。進(jìn)行成本分析，找出降低成本的因素，有效降低成本。? （6）使用計算機(jī)加強(qiáng)質(zhì)量數(shù)據(jù)的統(tǒng)計分析。充分利用質(zhì)量檢測數(shù)據(jù)，利用多種分析方法，進(jìn)行深入的統(tǒng)計和分析。有力地監(jiān)督和提高質(zhì)量水平。? （7）通過計算機(jī)實(shí)現(xiàn)企業(yè)的信息化管理，將廣大管理人員從繁瑣的手工勞動中解放出來，使他們有機(jī)會學(xué)習(xí)管理理論和提高管理技能，從本質(zhì)上提高企業(yè)管理人員的管理水平。? 3. raises the mechanical system industry management level with the information technology The above at present manages the question which exists seriously to affect the business management level, the management efficiency and enterprise's competitive ability. Uses modernized the management thought, the method and the computer network communication, realizes the machine manufacture enterprise's management innovation, the system innovation and the technical innovation is suspends in front of each enterprise the urgent duty. Therefore inside and outside the establishment joint factory computer network communications system, the choice advanced, is mature, the suitable business management demand enterprise resources plansERP, the customer relations managesCRM, supplies the chain to manageSCM, commercial intelligenceBI, software systemand so onelectronic commerce EC, through management consultation and service flow reorganization, optimized design enterprise's organizations and agencies, management pattern, service flow, application above software system, realization business management information. Overcomes the question which in at present business management exists, raises the business management level, the management efficiency and enterprise's competitive ability, is the enterprise the inevitably choice which makes facing the knowledge economy and the whole world economic integration. The system construction goal is: (1) completes to cover the entire company the computer network management information system. This system causes the enterprise the production management realization class, the fund class, the information flow and the work flows is highly unified and the parallel operation, and throughIntranet,in the Internet realization enterprise, exterior full information exchange and the enterprise and the outside relation, forms the effective agile supply and demand chain system. (2) uses the advanced productive plan control method. Breaks the wrap plan the way, proposes the earlier period and the production according to each kind of material purchase raises the earlier period establishment material demand plan. Establishes effectively, is nimble the productive plan management system which by the host productive plan, the material demand plan and the workshop work plan three levels of plans is composed, maximum limit reduces the product production cycle, the purchase cycle, the punctual delivery, the fast response customer demand, maximum limit reduces the stock and the cost, raises the post-sale service level. Has the condition the enterprise to carry out punctually producesJIT, the supplier manages storehouseVMI, the synchronized production and so on the advanced management. (3) realizes the entire company foundation data (for example material data, product structure data, product design craft data, productivity data and so on) unifies the production, the unification maintains and unifies the management, for uses after authorized each related department, truly achieves several, data sharing, avoids the redundancy. Furtherstraightens outthe enterprise through the ERP system establishment and the implementation the executive program, achieves the management the institution, the standardization and the scientific style. (4) in view of at present each control section in the information division situation, establishes take the customer as the central dynamic information feedback and the monitoring system, realizes signs, the design, the production, the purchase, the cost accounting end product to each duty from the contract delivers goods the entire process dynamic track, causes each duty to be in under the effective monitoring. (5) strengthens the financial control and the perfect cost accounting function. Truly establishes two levels of cost accounting system, uses the advanced cost accounting method, a more accurate core figures out the spare part cost and the product cost, is the sales quoted price and the financial calculation provides the reliable basis.

Chinese mechanical manufacturing industry management characteristic The mechanical manufacturing industry has the general character with other manufacturing industries management also to have the individuality; Mechanical manufacturing industry itself along with production type, production batch, production organization way different its management existence difference; China's manufacturing industry and the developed country compare, because the enterprise culture, the law, the system different also have its particularity. Under performs on these characteristics to elaborate: (1) the mechanical manufacturing industry is the typical separate manufacturing industry, its management software basis enterprise's production type, the production batch, the production organization way is different, needs the different solution. The next chart lists the production type division: These manufacture types characteristics: The separate manufacture - different material passes through the non- continual migration, through the different way, produces the different material and the product. If automobile, engine bed, airplane, computer, electrical appliances and so on. The flow industry - material after the mix, the separation, takes shape or the chemical reaction, the material mostly continuously through the same way, produces the valuable product. It divides into the continuous production, the volume production and the mix makes several kind of types. Requests the formula management, the wastage, the payment proportional to production in the management, the many kinds of measuring unit, the identical goods many quality rank, the batch number track, guarantees characteristic and so on nature time, generally uses specialized flow industry software. The piecework - product according to the order form design, according to the customer demand production, the product is very complex. The product production cycle all very is generally long. Sometimes a contract many times delivers according to the part. If three big power plants (big electrical machinery, steam turbine, boiler) heavy duty machinery, shipbuilding and so on. The production organization according to the craft division, the equipment is general. In the production management besides applies the multi- varieties small volume production the entire wrap method, must increase the network plan (project management), essential resources arrangement. HereCRMcertainly is unimportant. The multi- varieties small volume production - product is standard or selects and matches. The demand may be the forecast, or according to order form production, according to order form assembly. The production organization according to a craft characteristic minute workshop, the construction section, the teams and groups, like casts, hammers, the riveting, welds, the vehicle, the mill, digs, rubs, the assembly and so on. The productive plan characteristic is typicalMRPIIadds the disposition control. They also needCRM,SCMand so on. The mass production - product is the standard or minority selects and matches. The demand mainly depends on the forecast, also considers the order form. The production equipment is take the material (components, part) as the object composes a strip running water production line. The productive plan characteristic is traditionalMRPIIandthe JITmix manufacture, center the long-term plan and the volume production components use the material demand to planMRP, the execution plan useJIT, looked the board (el
