基于HDPEPVC 塑料管材無屑切割機結(jié)構(gòu)設(shè)計畢業(yè)論文.doc

徐州工程學院畢業(yè)設(shè)計(論文)I摘要通過對國內(nèi)外塑料管材機械生產(chǎn)線的研究分析，確定了無屑切割機做為本課題的主要設(shè)計內(nèi)容。無屑切割機用于塑料管材的定長切割，在切割過程中機架上的移動臺可以沿著管材擠出方向移動，并保持與管材的同步進給速度。在切割機的前部裝有托輪裝置，托輪起到支撐和導(dǎo)向的作用，針對不同管徑時要予以調(diào)節(jié)。當翻料架上的行程開關(guān)或編碼器發(fā)出切割信號后，機器夾緊裝置上的夾緊控制裝置夾牢管材，使管材在切割過程中相對固定，夾緊裝置為夾緊塊哈夫夾緊，在切割不同規(guī)格的管材時，調(diào)換相對應(yīng)的哈夫塊。切割工作指令的實現(xiàn)由電機通過V帶傳動，而刀片的切削進給由氣缸活塞桿緩緩?fù)七M而進行的，氣缸推力的大小可由氣缸的調(diào)節(jié)閥調(diào)節(jié)。刀片的無屑切割進給由移動盤和左右移動架來完成的，其中筒軸由軸承支承和定位，所以旋轉(zhuǎn)中心不變使切割機切割管材端面平整，尺寸規(guī)范。進刀深度由氣缸導(dǎo)向桿旁邊的限位調(diào)節(jié)絲桿調(diào)節(jié)控制。不同規(guī)格的厚度管材，調(diào)節(jié)絲桿的調(diào)節(jié)量大小不同。設(shè)計過程中查閱了大量國內(nèi)外的相關(guān)資料，所做的設(shè)計運用所學的所有專業(yè)課程。下文主要闡述塑料管材無屑切割機總體結(jié)構(gòu)設(shè)計。切割機設(shè)計主要包括，帶傳動機構(gòu)、夾緊機構(gòu)、切割機構(gòu)、切屑工作臺移動導(dǎo)軌、機架設(shè)計。關(guān)鍵詞:塑料管材；切割機；無屑式徐州工程學院畢業(yè)設(shè)計(論文)IIAbstractThroughtothedomesticandforeignplasticstubingmechanicalproductionlineresearchanalysis,haddeterminedthenon-filingscutterdoesforthistopicmaindesigncontent.Thenon-filingscutterusesintheplastictubingtodecidelongcuts,incutsprocessrackfromthemovingplationtobeallowedtosqueezeoutthetraversealongthetubing,andthemaintenanceandtubingsynchronizationentersforthespeed.Isloadedwithinthecutterfrontpartholdsaturnofequipment,holdsthewheeltoplaythestrutandtheguidancerole,inviewofdifferentcaliberwhenmustgivetoadjust.Afterturnsmaterialonthelimitswitchortheencodersendsoutcutsthesignal,machineclampclampsthecontrolequipmentfirmtubing,causesthetubingintocutintheprocesstoberelativelyfixed,theclampforclampsblockHafftoclamp,whencutsthedifferentspecificationthetubing,exchangesHaffblockwhichcorresponds.CutstheworkingordertherealizationbytheelectricalmachinerythroughVbelttransmission,butthebitcuttingforslowlypushesbythecylinderpistonrodthencarrieson,theaircylinderthrustforcesizemaybytheaircylinderregulatingvalveadjustment.Thebitnon-filingscutforbymove,casingofaxiswhichtheshiftingplateandaboutmovingplationcompletesbybearingsupportingandlocalization,thereforethecenterofrotationinvariablelycausesthecuttertocutthetubingendsurfacetobesmooth,sizestandard.Bitthedepthguidesnearbythepolebytheaircylinderthespacingadjustmentleadscrewregulatingcontrol.Thedifferentspecificationthicknesstubing,adjuststheleadscrewtheadjustmentquantitysizetobedifferent.Inthedesignprocesshasconsultedthemassivedomesticandforeigncorrelationdata,doesthedesignutilizationstudiesallspecializedcurricula.Asfollowsmainelaborationplastictubingnon-filingscutteroverallstructuraldesign.Thecutterdesignmainlyincludes,bringsthetransmissionsystem,tocuttheorganization,toclamptheorganization,Cutting-filingstheworktablemovestheguiderail,therackdesign.keywords:PlastictubingCutterNon-filingstype徐州工程學院畢業(yè)設(shè)計(論文)III目錄1緒論.11.1引言及HDPE/PVC簡介.11.2塑料管材生產(chǎn)線工作流程簡介.21.2.1塑料管材生產(chǎn)線結(jié)構(gòu)組成（本文僅以PVC波紋管為例）.21.2.2塑料管材生產(chǎn)過程.21.3PVC管材生產(chǎn)線特點.31.4設(shè)計方案的選擇比較.31.5設(shè)計方案綜述.42帶傳動機構(gòu)設(shè)計.62.1V帶機構(gòu)設(shè)計.62.1.1V帶的選擇.62.1.2帶傳動的分類（根據(jù)截面形狀不同）和性能比較.62.2V帶傳動的設(shè)計計算.72.3帶輪結(jié)構(gòu)設(shè)計.102.3.1V帶輪的設(shè)計要求：.102.3.2帶輪材料的選用.102.3.3結(jié)構(gòu)尺寸的設(shè)計.102.3.4帶輪的輪槽尺寸.112.3.5帶傳動的彈性滑動與打滑.123夾緊機構(gòu)設(shè)計.143.1夾緊裝置組成部件.143.2夾緊塊材料的選擇.143.3托輪裝置.153.3.1組成部件.153.3.2托滾材料的特殊選擇.154切割機構(gòu)設(shè)計.164.1切割機構(gòu)概要.164.1.1切割部件的組成.164.1.2工作原理.164.2傳動旋轉(zhuǎn)裝置的設(shè)計.164.2.1旋轉(zhuǎn)部件.164.2.2傳動體的尺寸計算.16徐州工程學院畢業(yè)設(shè)計(論文)IV4.3軸承的選用及潤滑.174.3.1軸承的類型.174.3.2軸承材料選擇.174.3.3設(shè)計中所選軸承介紹.174.4軸承驗算校核.184.4.1軸承的潤滑.194.4.2軸承的密封裝置.205切屑工作臺導(dǎo)軌設(shè)計.
