Embodiment Construction

[0013] Such as figure 1 As shown, the wave blocking device for explosive welding air shock wave of the present invention adopts steel structure welding to manufacture a hemispherical container 2, the top of the container 2 is provided with a smoke exhaust port 3, and the front end of the container is provided with an access door through an access channel 6.

[0014] Container 2 is preferably 20mm structure 20# steel welded main body, which is strengthened by tension bars to make the structure have mechanical stability and mechanical strength (marker 1 in the figure is a rib plate). The entrance and exit adopt arch lengthening and cross-shaped arch reinforcement structure. The whole container is fixed and strengthened with backfill soil after construction. During the explosive welding process, after the explosively processed plate enters through the entrance and is installed, the smoke exhaust port 3 is covered with a steel frame 4 and covered with a water bag 5 above the stee...

Abstract

The invention discloses a wave blocking device for explosive welding air impact waves. The wave blocking device comprises a semispherical steel container (2) fixed and reinforced by backfill soil, wherein reinforcing rib plates (1) are arranged vertically and transversely on the outer part of the container in a crossed manner; one side of the lower part of the container is connected with a barrel-shaped wave blocking device exiting and entering channel (6) and an exiting and entering door is additionally arranged; a smoke exhausting opening (3) is formed in the top of the container; a water bag (5) for completely covering the smoke exhausting opening is arranged on the smoke exhausting opening by arranging a covering object supporting frame (4). According to the wave blocking device, the water bag at the top of the smoke exhausting opening of an air wave blocking device is additionally arranged to cover, so that an influence range of the air impact waves caused by explosive welding is reduced effectively and the strength of the air impact waves is weakened obviously; the influences on people, buildings and the like in a certain range of the periphery by the explosive welding are controlled in a safe range; meanwhile, the influences of smoke dust and harmful gas, caused by explosion, are reduced by breaking and scattering the water bag under the effect of the impact waves, so that the aim of green and environment-friendly explosive machining is realized.

Description

technical field [0001] The invention relates to the technical field of explosive welding, and more specifically, relates to the improvement of explosive welding protection equipment. Background technique [0002] The composite steel plate produced by explosive welding technology has been widely and widely used in petroleum, chemical industry, metallurgy, machinery, aerospace, national defense construction and other industries and fields. The demand for special or rare and expensive functional metal materials also saves the manufacturing costs of these materials and equipment, making an important contribution to social development. However, the current explosive welding technology is characterized in that explosives are laid flat on the surface of functional metal plates for naked explosion. After the explosion, air shock waves, earthquake effects, smoke and harmful gases have become an important restrictive factor for the development of this technology. Especially the blast...
