学士学位论文题目：方形纸筒切管机设计哈尔滨远东理工学院学士学位论文PAGE\*MERGEFORMATII摘要方形纸管切割属于一个新的课题，目前国内尚无类似设备，也未见关于此类设备的论著，本课题研究的目的在于提供一种操作简便、高效率、高精度、成本低的方形纸筒切管机。本产品可以通过更换仿形凸轮的方式实现对多种规格方形纸管的仿形切割，更换凸轮快速、方便，针对不同规格纸管，使用对应规格的仿形凸轮，使切刀随纸管的转动同步进退，确保切刀对纸管圆周各处切割均匀；该产品具备一副对切刀架，有两把相对的切刀同时对纸管进行切割，可以使纸管的芯轴所受的径向力始终保持平衡而不致于弯曲，切刀的进给与返回采用气缸作为动力源，动作可靠、灵活。关键词：方形纸管；仿形凸轮；对切刀架；气缸；芯轴AbcstractSquarepapertubecuttingbelongstoanewproblem.Atpresent,there’snosimilarityequipmentortreatiseinourcountry.Thepurposetostudythisproblemistoaffordacheappapertubemachine.Itiseasytohandleandefficiencyandprecision.Thiskindofmachinecancutvariouskindsofpapertubebyreplacewithmodelcam.Andthisworkiseasyandfast.Accordingtothedifferentspecificationspapertube,Youcanusecorrespondingmodelingcam,Thepapertubeandtheknivesrunin-phase,Inordertocutthepapertubetoequality.Thismanufacturehaveadoublekniferest,whenthemachineworks,thispairofknivescutthepapertubeatthesametime.Itcanmaketheaxesofpapertubecameunderbalanceablestrength,andcann’tbeinbend.Thepowerofknives’advanceandbacktrackiscylinder,credibilityandagility.Keywords:QuadratePaperTube；ModelCam；DoubleKnifeRest；Cylinder；SpindlePAGE\*MERGEFORMATIV目录TOC\o"1-3"\h\uHYPERLINK\l_Toc8851摘要PAGEREF_Toc8851IHYPERLINK\l_Toc24266AbcstractPAGEREF_Toc24266IIHYPERLINK\l_Toc23393第1章绪论PAGEREF_Toc233931HYPERLINK\l_Toc28381.1课题背景PAGEREF_Toc28381HYPERLINK\l_Toc81831.1.1纸制品包装的特点的概述PAGEREF_Toc81831HYPERLINK\l_Toc307221.1.2纸包装的环境性能PAGEREF_Toc307222HYPERLINK\l_Toc255471.2生产现状PAGEREF_Toc255472HYPERLINK\l_Toc237831.2.1切深不均PAGEREF_Toc237832HYPERLINK\l_Toc132141.2.2刀具和芯轴的使用寿命短PAGEREF_Toc132143HYPERLINK\l_Toc171601.2.3芯轴刚度不足PAGEREF_Toc171603HYPERLINK\l_Toc33381.2.4生产效率低下PAGEREF_Toc33383HYPERLINK\l_Toc280201.3解决方案PAGEREF_Toc280203HYPERLINK\l_Toc233811.3.1切深不均的解决方案PAGEREF_Toc233813HYPERLINK\l_Toc176661.3.2刀具进给与返回PAGEREF_Toc176663HYPERLINK\l_Toc30711.4各工艺过
