冲压木块机的设计说明书.doc

I摘要冲压木块机在国外发展了十几年取得了一定的成果,该项技术在国外已经趋于成熟,而在我们国内还处于起步阶段,一旦获得成功将填补国内空白,发展前景十分广阔。冲压木块机是由链传动联系起来构成一个整体。本文摘要介绍了木块机的起源和发展现状,分析了该机器的结构特点制定了冲压木块机系统的总体布局和结构方案。同时还进行了电动机的选择计算、链传动的相关计算以及主轴的计算等。本文以结构设计为主。关键词冲压木块机主轴链轮园林机械2AbstractStampingblockmachinedevelopmentinforeigncountriesformorethantenyearshasachievedsomeresults,thetechnologyinforeigncountrieshasbecomemature,whileinourcountryisstillatthestartingstage,oncesuccessfulwillfillthegaps,andverybroadprospectsfordevelopment.Stampingblockmachineiscomposedofchaintransmissionlinkstoformawhole.Thispaperintroducestheoriginanddevelopmentoftheblockmachine,analyzesthestructurecharacteristicsofthedevelopedmachinestampingblockmachinesystemsoveralllayoutandstructureoftheprogramme.Alsoonthemotorselectionandcalculation,thecalculationofchaindriveandmaincalculation.Thispapermainlytostructuredesign.KeywordsStampingblockmachineaneccentricwheelsprocketgardenmachinery3目录摘要.........................................................................................................................IAbstract................................................................................................................II第1章绪论........................................................................................................11.1冲压木块机概述...................................................................................11.1.1冲压木块机发展现状........................................................................11.2冲压木块机的主要特点.......................................................................41.3冲压木块机设计的目的和意义...........................................................4第2章系统设计总体方案................................................................................72.1冲压木块机的结构设计.......................................................................72.2刀具体的确定.......................................................................................92.3拨料装置.............................................................................................122.4机架结构...............................................................................................14第3章机械系统设计方案的确定..................................................................163.1设计参数设定.....................................................................................163.2运动系统的设计计算.........................................................................163.2.1电动机的选择计算..................................................................163.2.2减速机的确定..........................................................................173.2.3链传动的特点与应用..............................................................183.2.4链传动的设计计算..................................................................193.2.5轴的设计说明..........................................................................223.2.6主轴的的结构设计..................................................................233.2.6轴的强度校核计算..................................................................273.2.7校核轴承寿命..........................................................................28第4章冲压木块机的使用说明书MJB205..................................................304.1主要用途及适用范围.........................................................................304.2主要规格及技术参数.........................................................................314.3主要结构及性能.................................................................................314.4安装与调整.........................................................................................324.5使用与操作.........................................................................................3344.6维护与保养.........................................................................................33结论..................................................................................................................34致谢..................................................................................................................35参考文献..............................................................................................................36CONTENTSAbstract................................................................................................................IIChapter1Introduction.....................................................................................11.1Overviewofstampingpiecesofwoodmachine....................................11.1.1Stampingpiecesofwoodmachinedevelopmentstatus.....................11.2Themainfeaturesofthemachineofstampingpiecesofwood............41.3Thepurposeandsignificanceofthedesignofstampingpiecesofwoodmachine..........................................................................................................4Chapter2Systemdesignoftheoverallprogram.........................................72.1Thestructuraldesignofstampingpiecesofwood................................72.2Theknifeconcretetodetermine............................................................92.3Dialfeedingdevice..............................................................................122.4Framestructure................
