Abstract
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.
Description
technical field [0001] The invention belongs to the technical field of structural parts processing, and relates to a preparation method of a corrugated sheet sandwich diaphragm assembly. Background technique [0002] Honeycomb structure or composite sandwich structure material is an important class of engineering structural materials. It can be seen everywhere in aviation, aerospace, ships and people's daily life, such as construction, decoration, rail transit and other industries, and plays an important functional and structural role. Therefore, the molding process and manufacturing process of various composite sandwich structure materials or honeycomb core structure materials are constantly innovating and developing, which in turn leads to the development and application of new sandwich honeycomb structure materials. [0003] Among the many sandwich honeycomb structure materials, the corrugated sheet sandwich diaphragm assembly is widely used in the field of mechanical st...
