本科毕业论文（设计）机械设计制造及其自动化摘 要多层热压机是生产胶合板、刨花板、中密度纤维板等人造板的主要设备。目前设备制造厂生产的热压机已基本定型，为了改进热压机的结构性能和降低制造成本，本文主要对五层侧压式热压机结构进行了设计,并对热压机的重要部件下托板的结构、强度和刚度进行了设计分析和计算,使下托板在结构上更加合理,降低了材料和能源消耗,提高了生产率。设计主要结合现有的设计理念，在符合设计要求的前提下，设计时热压机的机架整体上主要采纳了钢板焊接闭式结构，这种结构制造方便无需大型加工设备，并且，选材主要使用了工字钢、角钢等常用材料，使用钢板焊接的加工工艺，因而，生产工艺性较好，一般机械厂均能制造。设计中主要使用了 CAD、Pro\E 等工程制图软件，使用了 Pro\E 软件进行受力分析。关键词： 侧压式， 热压机 ，结构设计 ，受力分析AbstractThe multi-layered hot press is the production plywood, the shaving board, building board and so on density fiberboard major installations. At present the equipment factory production's hot press has finalized basically, to improve hot press's structure performance and reduce the production cost, this article mainly has carried on the design to five side thrust type hot press structure, and to hot press's important part under carrier's structure, the intensity and the rigidity has carried on the project analysis and calculates, causes the carrier to be more reasonable in the structure, reduced the material and the energy consumption, raised the productivity. The design main union existing design idea, in conforms to under the design requirements premise, in the design in press's rack whole has mainly used the steel plate welding closed type rack, this kind of structure manufacture convenience does not need the large-scale processing equipment, and, the selection has mainly used the I-steel, the angle steel and so on commonly used material, uses processing craft which the st...
