小型塑料挤出机设计和实现 机械知道专业VIP免费

小型塑料挤出机设计摘要在我国对外开放之后，国内经济得到较好的发展，效果显著，在经济的持续发展下，各个产业也需要加快脚步迅速发展起来，其中塑料工业便是其中之一。塑料工业在发展中不仅注重品质的发展，同时技术的进步也处于核心地位。在我国特色社会主义的发展中，该工业发挥了不可磨灭的作用。作为塑料工业的主要构成要素，塑料成型机械是生产塑料制品的主要工具，挤出成型就是目前普遍使用的主要方式。本文最先对成型理论、技术参数、辅助设备等主要知识开展叙述，之后对单杆塑料挤出机的功能、具体结构设计等进行充分且深入的分析，最终利用理论和现实相融合的形式对此技术开展后续的叙述和研究。关键词：挤出机；机械设计；塑料工艺。ABSTRACTOurcountryisstillintheprimarystageofsocialism,buttheeconomicdevelopmentofourcountryisadvancingrapidlyanddevelopingrapidly.Underthepowerfuleconomy,themajorindustriesaredevelopingrapidly,amongwhichtheplasticindustryisoneofthem.Thedevelopmentofplasticsindustrynotonlyfocusesonqualitydevelopment,butalsoadvancesintechnology.InthedevelopmentofsocialismwithChinesecharacteristics,theindustryhasplayedanindeliblerole.Plasticmoldingmachineryisanimportantpartoftheplasticsindustry,andanecessarymeanstocompletetheproductionofplasticproducts.Extrusionisoneofthemostimportantformingmethodsforplasticmolding.Thispapermainlydescribesitsbasicformingprinciple,structurecomposition,maintechnicalparameters,maincomponentsandrelatedcontrolsystemandauxiliarydevice.Onthebasisofexplainingtheworkingprinciple,basicstructureandrelevantprofessionalknowledgeofthesinglerodplasticextruder,itanalyzestheproblemsindepth,combinestheorywithpractice,andfromthemechanism,structureandplasticmoldingtechnology.Thesurfaceisdesigned.Keywords:extruder；mechanicaldesign；plastictechnology；目录1.绪论.....................................................................................................................................12挤出机总体方案的确定.....................................................................................................32.1螺杆挤出机的结构.......................................................................................................32.2挤出机总体布局的基本要求.......................................................................................42.3螺杆类型的确定...........................................................................................................42.3.1螺杆的工作性能指标评定...........................................................................42.3.2螺杆的选用原则..........................................................................................42.3.3螺杆的分类...................................................................................................52.3.4螺杆方案的确定...........................................................................................52.4机筒类型的确定...........................................................................................................52.5本章小结.......................................................................................................................53挤出机构设计.....................................................................................................................53.1聚苯乙烯的基本特性...................................................................................................63.2螺杆设计....................................................................................
