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 goo
