The invention belongs to the technical field of structural part
processing, and discloses a preparation method of a corrugated sheet sandwich partition board
assembly. The preparation method comprisesthe following steps that finish milling is carried out on a rough material, after holes are punched in the rough material by using electric sparks, linear
cutting is carried out to obtain an inner cavity and the
peripheral shape of a concentric-square-shaped square frame, then surface burrs are removed,
grinding is carried out to remove an electric
ablation layer, the inner cavity is subjected topolishing treatment, and an outer partition board is obtained; a blank is subjected to fine milling, linear
cutting is carried out on the blank according to the size requirement to obtain a corrugated shape, surface burrs are removed,
grinding is carried out to remove the electric
ablation layer, the surface is subjected to
polishing treatment, and a corrugated sheet is obtained; and the obtainedouter partition board and corrugated sheet are cleaned, amorphous foil-shaped
brazing filler metal of 0.05 mm is prearranged on the surface of the corrugated sheet through
spot welding treatment, then the corrugated sheet and the
brazing filler metal are pressed into an inner cavity of the outer partition board together, the outer partition board is pressed through a pressing plate tool, the corrugated sheet is welded into the inner cavity of the outer partition board through
brazing treatment, and the corrugated sheet sandwich partition board
assembly is obtained. The preparation method is simple and scientific in link.
