Embodiment

[0114] The glass microspheres and the emulsification matrix are mixed according to the mass fraction of 25% and 75% to prepare the emulsion explosive, and put into a 250*200*10mm drug frame. Cut 0.2mm, 0.1mm copper foil and 0.1mm stainless steel foil to a size of 200mm×150mm, as cladding, substrate and intermediate layer. And glue the copper foil of 200*150*0.2mm on the aluminum plate of 250*200*1mm thickness with PET double-sided adhesive (the adhesive of the substrate 6 and the bottom protection plate 7, and the cover plate 5 and the top protection plate 3 adhesives). From bottom to top aluminum plate and 0.2mm copper foil bond-0.1mm stainless steel foil-0.1mm copper foil-0.1mm stainless steel foil-0.1mm copper foil-0.1mm stainless steel foil-0.2mm copper foil and aluminum plate bond - The explosives are arranged in order, and the brackets 8 are used to fix and maintain a gap of 1mm between each layer. The brackets 8 are coated with adhesive and bonded and fixed with the me...

Abstract

The invention discloses an energy control method capable of being applied to multi-layer explosive welding. According to the method, metal protection plates are bonded with a cladding plate and a substrate, so that damage of explosion to a composite material is avoided, and control of welding parameters is achieved. A cladding is bonded with the top metal protection plate, the substrate is bonded with the bottom metal protection plate, and a PET double-sided adhesive, a common double-sided adhesive, glue or butter is adopted as a bonding material. Through selection of the top protection plate, the bottom protection plate, materials and sizes, the welding process of each layer can be controlled. Fixed distances are reserved between the middle layers, between the middle layers and the cladding plate and between the middle layers and the substrate through spacing bars, and the thin middle layers are prevented from drooping and bending through mechanical fixing or bonding fixing. The metal protection plates can regulate and control parameter changes in the explosive welding process, so that the performance of the multi-layer composite material is more uniform, and meanwhile, the influence of boundary sparse waves is reduced.

Description

technical field [0001] The invention relates to the technical field of explosive welding, in particular to an energy control method applicable to multilayer explosive welding. Background technique [0002] Laminated metal composites (laminated metal composites) have been found to have excellent properties since ancient times; for example, ancient Indians used multiple folding and forging techniques to make Damascus swords from mild and hard steels, nanoscale multilayer structures and dispersed The carbides give the Damascus sword its exceptional strength and toughness. Other examples exist, including composites from China, Thailand, Indonesia, Germany, Great Britain, Belgium, France and Persia. To provide better performance has also found the expression of modern materials. Laminated materials have unusual properties and have broad application prospects as engineering composite materials, such as the design of laminated composite materials in the former Soviet Union has be...
