Abstract

The invention discloses a light lattice sandwich plate and a method for manufacturing the same by mechanical drilling, belongs to the field of mechanical processing and solves the problems that the structural performance of the sandwich plates formed by the conventional method is poor and batch production cannot be realized due to the process problems. In the light lattice sandwich plate, an upper top surface of a porous corrugated plate is fixed with an upper panel; a lower bottom surface of the porous corrugated plate is fixed with a lower panel; and a row of through holes are distributed on each inclined side surface of the porous corrugated plate. The method for manufacturing the light lattice sandwich plate by mechanical drilling comprises the following steps of: 1, fixing the corrugated plate with the upper and lower panels; 2, fixedly clamping the corrugated plate on a drilling machine and drilling; and 3, drilling to finish the manufacturing of the light lattice sandwich plate by a set procedure. Or the method comprises the following steps of: 1, performing pretreatment on the corrugated plate; 2, fixedly clamping the corrugated plate on the drilling machine and drilling; and 3, after finishing the drilling by the set procedure, fixing the drilled corrugated plate with the upper and lower panels to finish the manufacturing of the light lattice sandwich plate.

Description

technical field [0001] The invention relates to a lightweight lattice sandwich panel and a method for preparing the panel by mechanical drilling, belonging to the field of mechanical processing. Background technique [0002] At present, there are mainly two kinds of light-weight lattice sandwich panels: rolling method and investment casting method for lattice sandwich panels made of metal materials; mainly two methods for lattice sandwich panels made of fiber reinforced composite materials. There are mold hot pressing method, mold assembly method, fiber weaving method and mechanical assembly method. Analyze the existing problems in the following [0003] Rolling method: Due to the elastic deformation of the metal material during the rolling process, the nodes of the lattice core are often not on the same plane, and the node area of ​​the lattice structure prepared by the rolling method is relatively small. [0004] Investment casting method: Since the metal fluidity is not...
