Abstract
The embodiment of the invention relates to the technical field of explosive welding, in particular to an explosive welding method and device for a rotation welding face and a duplex-metal sliding-contact-type electricity transmission and discharging device. The method comprises the steps of fixing a base plate; fixing a doubling plate, and keeping an explosion spacing between the base plate and the doubling plate, wherein a supporting piece and the base plate or doubling plate are prepared from the same material; arranging explosives, wherein the explosives are arranged on the side face, deviating from the base plate, of the doubling plate with uniform thickness; and conducting explosive welding, wherein under the effect of explosive shock waves, the doubling plate moves towards the base plate and is combined with the base plate. The embodiment of the invention has the advantages that the rotation welding face of the base plate and the rotation welding face of the doubling plate are inrigorous correspondence, and the positioning precision is guaranteed; the shearing performance of a combined face is not lower than the lower shearing strength between the base plate and the doublingplate; and meanwhile, the explosive welding device has excellent electrical conductivity (the base plate is prepared from silver, copper or aluminum with excellent electrical conductivity) and wear resistance (the doubling plate is prepared from a wear-resistance metal material), and therefore, mutual advantages of the doubling layer and the base layer are complemented.
Description
technical field [0001] The invention relates to the technical field of explosive welding, in particular to an explosive welding method and equipment for a rotary welding surface, and a bimetallic sliding contact discharge device. Background technique [0002] Explosive welding is a technology that uses the explosion of explosives as an energy source, and uses the explosive action to push two metals or multiple metals into high-speed collisions, so that the metal bodies are welded together. Explosive welding is a complex process. After the explosive is detonated, it will generate a shock wave that propagates along the surface of the doubler plate, causing the pressure of oblique collision at the collision point to be far greater than the dynamic yield strength of the metal at the point. Under the action of high pressure, the two The metals are firmly welded together. Explosive welding technology has been developed for a long time due to its uniqueness, and has the following ...
