枝桠材用小型切片机设计说明书.doc

黑龙江工程学院本科生毕业设计I摘要为了适应我国木材资源严重不足且分布不集中的特点，设计了这种体积小、生产能力大且削片合格率高的枝桠材用小型切片机，来满足林区小型工厂的生产或木材家具厂的碎料加工，以节约木材资源。在此次设计中，机架、左右上盖都采用了焊接件，降低了整机的重心，有效地增强了整机的稳定性；电机和轴之间通过皮带传动，缓和了载荷冲击，防止过载给飞刀等主要部件带来的损坏；轴通过两个圆锥滚子轴承与机架连接，防止轴产生较大的跳动影响木片合格率；刀盘和轴之间配合紧密；飞刀用压块夹紧，牢固稳定，方便拆装和更换。此削片机最适合加工枝桠材和小径级的原木，投资小，价格低廉且见效快，非常适合作坊式工厂和小型个体企业生产。关键词：削片机；盘式削片机；木片；刀盘；飞刀黑龙江工程学院本科生毕业设计IIABSTRACTForadaptingthecharacteristicsoftheseriousshortageofthewoodresourcesandbad-distributedcondition,akindofbranchchipperisdesigned,whichhassmallphysicalvolume,highefficiencyandthequalificationratetomeettheneedsofsavingthewoodresourcesandprocessingfragmentsinmicroandfurniturefactory.Inthisdesign,framework,theleftcoverandrightcoverarecasting,whichcanlowerthecenterofgravityofthewholemachineandlargerthestabilityofthewholemachine.Themotorisconnectedwiththespindlebystalkbelt,whichcanmollifytheimpact,preventthedamagewhichcausedbyoverloadingcomponentssuchasthefly-cutteretc.Thespindleisconnectedwithframeworkbytwoconesrollsofsub-bearingspreventsrunoutofoperationprocessonthespindle.Thefitbetweenthecuttingdishandthespindleisthegradienttightmatch,whichistightmatch.Thestudboltsisusedtopressthefly-cutter.Themethodwhichiscone-shapedofconnectionisfirm.Itisconvenientfordismountingandreplacement.Thischipperisquitesuitabletoprocessbranchandthelogofthefootpathclass,whichhasasmallinvestmentandlowprice.Itcanbeusedinthesmallscaledindividualbusinessenterpriseproduceschip.Keywords:Chipper；DiscChipper；Chip；CuttingDish；Fly-cutter黑龙江工程学院本科生毕业设计目录摘要·············································································································IAbstract······································································································II第1章绪论································································································11.1课题背景、目的及意义············································································11.2国内外研究状况和相关领域中已有的研究成果············································21.3选题的设计设想、设计方法和改进····························································41.4预期结果·······························································································4第2章盘式削片机的总体设计··································································52.1盘式削片机的方案设计·············································································52.2盘式削片机的总体设计·············································································72.3削片原理································································································92.4本章小结······························································································14第3章主要技术参数的确定和计算·························································153.各树种单位切削力····················································································153.2切削功率的计算····················································································183.3电机的选择···························································································183.4飞刀伸出量的确定·················································································193.5生产能力的确定····················································································193.6本章小结·····························································································19第4章主要部件的设计计算····································································204.1刀盘结构设计及尺寸的确定····································································204.2装刀部分设计和底刀部分设计·································································214.3主轴的结构设计····················································································224.3.1轴的最小直径计算······································································224.3.2轴承的选择················································································234.4传动比计算和大、小带轮的计算······························································24黑龙江工程学院本科生毕业设计4.5进料槽设计计算····················································································274.6本章小结·····························································································27第5章各部件的校核和验算····································································285.1轴的强度校核························································································285.2刀盘的校核···························································································335.3轴承的校核··························································································365.4本章小结·····························································································38结论···········································································································39参考文献···································································································40致谢···········································································································41附录······························································································
