變尺寸要求紙張裁剪機(jī)設(shè)計(jì)畢業(yè)論文.doc

大連輕工業(yè)學(xué)院2006屆本科生畢業(yè)設(shè)計(jì)（論文）I摘要紙張裁剪機(jī)是一種通用的設(shè)備，應(yīng)用范圍非常廣泛，幾乎每個(gè)印刷企業(yè)都要配置紙張裁剪機(jī)，紙張裁剪機(jī)在印刷機(jī)械產(chǎn)品中占重要的地位。隨著社會(huì)的進(jìn)步和科學(xué)的發(fā)展，造紙業(yè)、印刷業(yè)對紙張裁剪機(jī)提出了更高要求。該文針對國內(nèi)紙張裁剪機(jī)只能單方向剪裁、只能剪裁固定尺寸紙張的缺陷，將橫向剪裁與縱向剪裁分開，從縱向滾刀的安裝方式和橫刀的剪裁時(shí)間控制為突破口，設(shè)計(jì)了一種可以縱橫雙向剪裁、可以按照商家要求剪裁可變尺寸紙張的紙張裁剪機(jī)。用于從事商標(biāo)、名片和各種印刷制品的剪裁工作。該紙張裁剪機(jī)結(jié)構(gòu)簡單、動(dòng)作簡潔快速，全套工作流程由PLC控制，具有剪裁質(zhì)量高，生產(chǎn)效率高的優(yōu)點(diǎn)。整個(gè)設(shè)計(jì)過程詳細(xì)論證了其原理方案的可行性和機(jī)構(gòu)的合理性，結(jié)構(gòu)設(shè)計(jì)全用先進(jìn)的CATIA軟件造型、裝配，真實(shí)地展示了整個(gè)系統(tǒng)的結(jié)構(gòu)尺寸和工作原理。在設(shè)計(jì)過程中，通過對實(shí)際應(yīng)用產(chǎn)品的設(shè)計(jì)，增強(qiáng)了對所學(xué)專業(yè)知識的掌握，提高了對設(shè)計(jì)思想理念的理解和實(shí)際運(yùn)用能力，同時(shí)培養(yǎng)了自己獨(dú)立完成設(shè)計(jì)任務(wù)的能力，認(rèn)識到了嚴(yán)謹(jǐn)?shù)墓ぷ鲬B(tài)度對設(shè)計(jì)產(chǎn)品質(zhì)量的重要作用。當(dāng)然，在本設(shè)計(jì)中，仍然存在許多不完善的地方，在以后的設(shè)計(jì)中會(huì)加以借鑒，逐步改進(jìn)。關(guān)鍵詞：變尺寸；雙向剪裁；CATIA軟件；紙張裁剪機(jī)大連輕工業(yè)學(xué)院2006屆本科生畢業(yè)設(shè)計(jì)（論文）IIAbstractPaperscuttingmachineisakindofgeneralusedequipments,itsapplicationisveryextensive,almosteachprintingbusinessenterpriseshaveinstalledpapercuttingmachine,thepapercuttingmachinehasanimportantpositioninprintingmachineproduct.Alongwiththeprogressofthesocietyandthedevelopmentofscience,therewillbeahigherrequesttothepaperinpapermakingindustryandprint.Thistextaimatthelimitationthatthelocalpapercuttingmachinecancutonlyonesideandonlyfixeddimension,separatingacrosscuttingandverticalcutting,breakingfromtheinstallationoftheverticalhobandthetimecontroloftheacrosshob.Designakindofcuttingmachinewhichcancutfrombothacrossandverticalandcancutalterablesizeaccordingtotherequestofthemerchant.Usedintheworkofcuttinglabel,businesscardandmanykindsofpresswork.Thestructureofthiskindofcuttingmachineisverysimpleanditsmotionisprompt.ThecompleteworkflowiscontrolledbythePLCsystem,havingtheadvantageofhighqualityofcuttingandworkingwithefficiency.Thewholedesignprocessdemonstratesthefeasibilityofthistheoryandtherationalityoftheinstitution.AllofthestructuredesignusetheCATIAsoftwaretoshapeandassemble,displayingthesizeofthestructureandworkprincipleofthewholesystemreally.Duringthedesign,throughthedesignoftheactualapplyproduct,enhancethecomprehensionofspecialtyacknowledgeandimprovethecomprehensionandactualapplyabilityofthedesignidea.Atthesametime,developtheabilityofcompletingdesignmissiononeselfandunderstandtheimportanteffectofthereligiousworkingattitudetodesignthequalityoftheproduct.Certainly,theremustbesomeplacesnotperfectinthisdesign.Iwillusethemforreferenceinthelaterdesigntoimprovegreatly.Keywords：Variationsize；bidirectionalcutting；CATIAsoftware；thepapercuttingmachine大連輕工業(yè)學(xué)院2006屆本科生畢業(yè)設(shè)計(jì)（論文）III目錄摘要.IAbstract.II第一章前言.11.1紙張裁剪機(jī)的簡介.11.2紙張裁剪機(jī)國內(nèi)外情況介紹.11.2.1國內(nèi)情況.11.2.2進(jìn)口情況.21.3紙張裁剪機(jī)市場前景.21.4紙張裁剪機(jī)的發(fā)展趨勢.3第二章可調(diào)尺寸紙張裁剪機(jī)原理方案的設(shè)計(jì).42.1現(xiàn)有紙張裁剪機(jī)的結(jié)構(gòu)原理分析.42.1.1模切機(jī).42.1.2直刃裁紙機(jī).52.1.3滾刀裁剪機(jī).82.2可調(diào)尺寸紙張裁剪機(jī)原理方案的設(shè)計(jì).82.2.1功能原理分析：.92.2.2運(yùn)動(dòng)原理分析：.112.2.3總結(jié)分析：.12第三章可調(diào)尺寸紙張裁剪機(jī)結(jié)構(gòu)尺寸的設(shè)計(jì).133.1縱向裁紙機(jī)構(gòu)設(shè)計(jì).133.1.1縱向裁紙刀的結(jié)構(gòu)設(shè)計(jì).133.1.2縱向裁紙刀的安裝設(shè)計(jì).143.2橫向裁紙機(jī)構(gòu)設(shè)計(jì).163.2.1橫向裁紙刀的結(jié)構(gòu)設(shè)計(jì).16大連輕工業(yè)學(xué)院2006屆本科生畢業(yè)設(shè)計(jì)（論文）IV3.2.2橫向裁紙刀的安裝設(shè)計(jì).173.3控制裝置、總體結(jié)構(gòu)的設(shè)計(jì).183.3.1控制裝置的設(shè)計(jì).183.3.2總體結(jié)構(gòu)的設(shè)計(jì).18第四章零部件設(shè)計(jì).254.1縱向裁紙機(jī)構(gòu)零件尺寸的設(shè)計(jì).254.1.1軸的設(shè)計(jì).254.1.2電動(dòng)機(jī)功率選擇：.274.1.3刀具設(shè)計(jì)：.274.1.5儀器儀表滾動(dòng)軸承的選擇.294.2橫向裁紙機(jī)構(gòu)零件尺寸的設(shè)計(jì).294.2.1絲杠設(shè)計(jì).294.2.2光杠設(shè)計(jì).314.2
