摘 要
多層熱壓機(jī)是生產(chǎn)膠合板、刨花板、中密度纖維板等人造板的主要設(shè)備。目前設(shè)備制造廠生產(chǎn)的熱壓機(jī)已基本定型，為了改進(jìn)熱壓機(jī)的結(jié)構(gòu)性能和降低制造成本，本文主要對(duì)五層側(cè)壓式熱壓機(jī)結(jié)構(gòu)進(jìn)行了設(shè)計(jì),并對(duì)熱壓機(jī)的重要部件下托板的結(jié)構(gòu)、強(qiáng)度和剛度進(jìn)行了設(shè)計(jì)分析和計(jì)算,使下托板在結(jié)構(gòu)上更加合理,降低了材料和能源消耗,提高了生產(chǎn)率。設(shè)計(jì)主要結(jié)合現(xiàn)有的設(shè)計(jì)理念，在符合設(shè)計(jì)要求的前提下，設(shè)計(jì)時(shí)熱壓機(jī)的機(jī)架整體上主要采用了鋼板焊接閉式結(jié)構(gòu)，這種結(jié)構(gòu)制造方便無需大型加工設(shè)備，并且，選材主要使用了工字鋼、角鋼等常用材料，使用鋼板焊接的加工工藝，因而，生產(chǎn)工藝性較好，一般機(jī)械廠均能制造。設(shè)計(jì)中主要使用了CAD、Pro\E等工程制圖軟件，使用了Pro\E軟件進(jìn)行受力分析。

關(guān)鍵詞： 側(cè)壓式， 熱壓機(jī) ，結(jié)構(gòu)設(shè)計(jì) ，受力分析
Abstract
The 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 steel plate welds, thus, the production technology capability is good, generally the machine shop can make. In the design has mainly used CAD, engineering drawing soft wares Pro \ E and so on, used the software Pro \ E to carry on the stress analysis.

Key words: lateral pressure type, thermal-pressing machine, structural design, stress analysis
