Problems solved by technology

[0012] This technology has the following characteristics: ① It overcomes the explosion-proof ball produced by single-layer metal material. The wall thickness of the shell is usually more than 30mm, and the material used must be high-strength steel. It can only be pressed after heating, and the surface of the metal plate caused by heating will produce a series of problems such as oxide layer, alloy burning loss, and material strength decrease.

Embodiment Construction

[0014] The present invention can be realized by the following process: 1. the sheet metal with thickness less than 3 millimeters, through calculation blanking respectively is the required rectangular material of rolling a joint cylinder and the fan-shaped material ( It is also possible to cut all the metal plates into several pieces and roll them into fan-shaped materials required for the frustum body), and then weld the rolled metal plates into a spherical inscribed polyhedron according to the requirements of the design structure, and then weld the first The metals of the second layer, the third layer.....are sequentially assembled and welded on the outer end of the polyhedral metal shell inscribed in the ball of the previous layer. Thus at first obtain a multilayer spherical inscribed polyhedron that is formed by layering of multilayer metal materials, such as (6), (8), (12), (13) among accompanying drawing 2; 2. with many groups, (each The group is two metal discs) to seal ...

Abstract

The present invention relates to the field of metal ball type explosion-proof container manufacture technology, and belongs to a manufacture technique of ball type explosion-proof container formed by using thin-sheet multi-layer metal material and adopting mouldless explosion process. The production cost of the multi-layer metal ball type explosion-proof container produced by adopting said invention only is 1 / 50 of that of single-layer metal ball type explosion-proof container made up by traditional technique, and its production period is 1 / 100 of that of single-layer metal ball type explosion-proof container, and its protective performance also is greatly superior to existent other explosion-proof materials.

Description

(1).Technical field [0001] The invention relates to the technology of the spherical explosion-proof container which is made of thin-plate multi-layer metal material without mold explosion in the field of metal spherical explosion-proof container manufacturing. The multi-layer metal spherical explosion-proof container produced by this technology can be widely used to prevent damage to surrounding personnel and buildings when dangerous goods such as explosives explode. (2). Background technology [0002] The situation of comprehensive social security is becoming more and more severe, and various forms of explosive crimes are frequently sabotaged on different occasions. In response to this phenomenon, the departments in charge of public security of various governments have tried various methods to strengthen security protection and have mentioned the entire agenda. [0003] Putting explosion-proof blankets, explosion-proof fences, explosion-proof barrels, and explosion-proof b...
