基于HDPEPVC 塑料管材无屑切割机结构设计毕业论文.doc

徐州工程学院毕业设计论文I摘要通过对国内外塑料管材机械生产线的研究分析,确定了无屑切割机做为本课题的主要设计内容。无屑切割机用于塑料管材的定长切割,在切割过程中机架上的移动台可以沿着管材挤出方向移动,并保持与管材的同步进给速度。在切割机的前部装有托轮装置,托轮起到支撑和导向的作用,针对不同管径时要予以调节。当翻料架上的行程开关或编码器发出切割信号后,机器夹紧装置上的夹紧控制装置夹牢管材,使管材在切割过程中相对固定,夹紧装置为夹紧块哈夫夹紧,在切割不同规格的管材时,调换相对应的哈夫块。切割工作指令的实现由电机通过V带传动,而刀片的切削进给由气缸活塞杆缓缓推进而进行的,气缸推力的大小可由气缸的调节阀调节。刀片的无屑切割进给由移动盘和左右移动架来完成的,其中筒轴由轴承支承和定位,所以旋转中心不变使切割机切割管材端面平整,尺寸规范。进刀深度由气缸导向杆旁边的限位调节丝杆调节控制。不同规格的厚度管材,调节丝杆的调节量大小不同。设计过程中查阅了大量国内外的相关资料,所做的设计运用所学的所有专业课程。下文主要阐述塑料管材无屑切割机总体结构设计。切割机设计主要包括,带传动机构、夹紧机构、切割机构、切屑工作台移动导轨、机架设计。关键词塑料管材切割机无屑式徐州工程学院毕业设计论文IIAbstractThroughtothedomesticandforeignplasticstubingmechanicalproductionlineresearchanalysis,haddeterminedthenonfilingscutterdoesforthistopicmaindesigncontent.Thenonfilingscutterusesintheplastictubingtodecidelongcuts,incutsprocessrackfromthemovingplationtobeallowedtosqueezeoutthetraversealongthetubing,andthemaintenanceandtubingsynchronizationentersforthespeed.Isloadedwithinthecutterfrontpartholdsaturnofequipment,holdsthewheeltoplaythestrutandtheguidancerole,inviewofdifferentcaliberwhenmustgivetoadjust.Afterturnsmaterialonthelimitswitchortheencodersendsoutcutsthesignal,machineclampclampsthecontrolequipmentfirmtubing,causesthetubingintocutintheprocesstoberelativelyfixed,theclampforclampsblockHafftoclamp,whencutsthedifferentspecificationthetubing,exchangesHaffblockwhichcorresponds.CutstheworkingordertherealizationbytheelectricalmachinerythroughVbelttransmission,butthebitcuttingforslowlypushesbythecylinderpistonrodthencarrieson,theaircylinderthrustforcesizemaybytheaircylinderregulatingvalveadjustment.Thebitnonfilingscutforbymove,casingofaxiswhichtheshiftingplateandaboutmovingplationcompletesbybearingsupportingandlocalization,thereforethecenterofrotationinvariablelycausesthecuttertocutthetubingendsurfacetobesmooth,sizestandard.Bitthedepthguidesnearbythepolebytheaircylinderthespacingadjustmentleadscrewregulatingcontrol.Thedifferentspecificationthicknesstubing,adjuststheleadscrewtheadjustmentquantitysizetobedifferent.Inthedesignprocesshasconsultedthemassivedomesticandforeigncorrelationdata,doesthedesignutilizationstudiesallspecializedcurricula.Asfollowsmainelaborationplastictubingnonfilingscutteroverallstructuraldesign.Thecutterdesignmainlyincludes,bringsthetransmissionsystem,tocuttheorganization,toclamptheorganization,Cuttingfilingstheworktablemovestheguiderail,therackdesign.keywordsPlastictubingCutterNonfilingstype徐州工程学院毕业设计论文III目录1绪论......................................................................11.1引言及HDPE/PVC简介...................................................11.2塑料管材生产线工作流程简介............................................21.2.1塑料管材生产线结构组成(本文仅以PVC波纹管为例)..................21.2.2塑料管材生产过程...................................................21.3PVC管材生产线特点....................................................31.4设计方案的选择比较....................................................31.5设计方案综述..........................................................42带传动机构设计............................................................62.1V带机构设计..........................................................62.1.1V带的选择..........................................................62.1.2带传动的分类(根据截面形状不同)和性能比较..........................62.2V带传动的设计计算....................................................72.3带轮结构设计.........................................................102.3.1V带轮的设计要求................................................102.3.2带轮材料的选用....................................................102.3.3结构尺寸的设计....................................................102.3.4带轮的轮槽尺寸....................................................112.3.5带传动的弹性滑动与打滑............................................123夹紧机构设计.............................................................143.1夹紧装置组成部件.....................................................143.2夹紧块材料的选择.....................................................143.3托轮装置.............................................................153.3.1组成部件..........................................................153.3.2托滚材料的特殊选择................................................154切割机构设计.............................................................164.1切割机构概要.........................................................164.1.1切割部件的组成....................................................164.1.2工作原理..........................................................164.2传动旋转装置的设计...................................................164.2.1旋转部件..........................................................164.2.2传动体的尺寸计算..................................................16徐州工程学院毕业设计论文IV4.3轴承的选用及润滑.....................................................174.3.1轴承的类型........................................................174.3.2轴承材料选择......................................................174.3.3设计中所选轴承介绍................................................174.4轴承验算校核.........................................................184.4.1轴承的润滑........................................................194.4.2轴承的密封装置....................................................205切屑工作台导轨设计...
