Problems solved by technology

The above-mentioned method of determining the spacing s is different from the angle of consideration of the problem, and the spacing s determined by it is also different to a certain extent.
At the same time, these methods of determining the spacing only give the spacing range, and do not point out the parameters of the optimal spacing

Embodiment Construction

[0025] A user needs 20 pieces of composite materials made of 4mm*2000mm*8000mm304 stainless steel and 30mm*2000mm*8000mmQ235 ordinary steel as the base material.

[0026] In this case, according to the above formula, the distance between the base and cladding plates is about 8-12mm, and the actual explosive welding distance is 12mm, which not only reduces the thickness of the charge, but also successfully realizes the explosive welding of such composite materials. , the recombination rate is 100%, the interfaces are micro-wavy interfaces, and the bonding strength has reached 320MPa.

[0027] The parts not involved in the present invention are the same as the prior art or can be realized by adopting the prior art.

Abstract

The invention provides an explosive welding optimal interval charge parameter determining method. In other words, the quantitative relation between a base and compound plate interval S, a collision speed V and compound plate movement acceleration a is established. According to an upper limit principle, the upper limit interval calculated by taking the maximum collision speed of a compound plate is the optimal interval, and the charge thickness parameter is decreased at the moment so that the explosion welding interface can be in tiny wavy high-quality combination.

Description

technical field [0001] The invention relates to a method for determining the optimal spacing charge parameters for explosive welding, and belongs to the technical field of explosive welding metal composite material charge methods and techniques. Background technique [0002] The explosive welding spacing refers to the distance between the doubler board and the base plate. In order for the doubler board to obtain the collision speed required for explosive welding, it is necessary to ensure a certain board spacing. Some researchers believe that the distance between two plates is generally 0.5 to 1.0 times the thickness of the doubler plate; Ezra believes that the distance is related to the specific gravity of the doubler plate material. When the specific gravity of the doubler plate material is less than 5, between 5 and 10, greater than At 10 o'clock, the spacing is 1 / 2~2 / 3, 1 / 2~1, 2 / 3~2 times of the doubler board thickness respectively. In addition, Stivers and Wittman gave...
