枝椏材用小型切片機(jī)設(shè)計(jì)說明書.doc

黑龍江工程學(xué)院本科生畢業(yè)設(shè)計(jì)I摘要為了適應(yīng)我國木材資源嚴(yán)重不足且分布不集中的特點(diǎn)，設(shè)計(jì)了這種體積小、生產(chǎn)能力大且削片合格率高的枝椏材用小型切片機(jī)，來滿足林區(qū)小型工廠的生產(chǎn)或木材家具廠的碎料加工，以節(jié)約木材資源。在此次設(shè)計(jì)中，機(jī)架、左右上蓋都采用了焊接件，降低了整機(jī)的重心，有效地增強(qiáng)了整機(jī)的穩(wěn)定性；電機(jī)和軸之間通過皮帶傳動(dòng)，緩和了載荷沖擊，防止過載給飛刀等主要部件帶來的損壞；軸通過兩個(gè)圓錐滾子軸承與機(jī)架連接，防止軸產(chǎn)生較大的跳動(dòng)影響木片合格率；刀盤和軸之間配合緊密；飛刀用壓塊夾緊，牢固穩(wěn)定，方便拆裝和更換。此削片機(jī)最適合加工枝椏材和小徑級(jí)的原木，投資小，價(jià)格低廉且見效快，非常適合作坊式工廠和小型個(gè)體企業(yè)生產(chǎn)。關(guān)鍵詞：削片機(jī)；盤式削片機(jī)；木片；刀盤；飛刀黑龍江工程學(xué)院本科生畢業(yè)設(shè)計(jì)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黑龍江工程學(xué)院本科生畢業(yè)設(shè)計(jì)目錄摘要IAbstractII第1章緒論11.1課題背景、目的及意義11.2國內(nèi)外研究狀況和相關(guān)領(lǐng)域中已有的研究成果21.3選題的設(shè)計(jì)設(shè)想、設(shè)計(jì)方法和改進(jìn)41.4預(yù)期結(jié)果4第2章盤式削片機(jī)的總體設(shè)計(jì)52.1盤式削片機(jī)的方案設(shè)計(jì)52.2盤式削片機(jī)的總體設(shè)計(jì)72.3削片原理92.4本章小結(jié)14第3章主要技術(shù)參數(shù)的確定和計(jì)算153.各樹種單位切削力153.2切削功率的計(jì)算183.3電機(jī)的選擇183.4飛刀伸出量的確定193.5生產(chǎn)能力的確定193.6本章小結(jié)19第4章主要部件的設(shè)計(jì)計(jì)算204.1刀盤結(jié)構(gòu)設(shè)計(jì)及尺寸的確定204.2裝刀部分設(shè)計(jì)和底刀部分設(shè)計(jì)214.3主軸的結(jié)構(gòu)設(shè)計(jì)224.3.1軸的最小直徑計(jì)算224.3.2軸承的選擇234.4傳動(dòng)比計(jì)算和大、小帶輪的計(jì)算24黑龍江工程學(xué)院本科生畢
