Problems solved by technology

[0003] The flanges in the prior art need to meet a certain thickness requirement. The flanges on the explosion-proof box or cover are usually welded, and the flange is welded to the box or cover along the edge of the circle, and the production efficiency is extremely high. Low, so the production cost is high, and once the welding effect is not good, there will be gaps, which will affect the explosion-proof effect and poor safety performance

Embodiment Construction

[0030] The invention provides an explosion-proof box, which includes a box body 2 and a cover body 3 .

[0031] The box 2 includes a main body of the box and a flange structure 1 arranged on the main body of the box. The flange structure 1 includes a flange core 11 and a flange body formed by casting and wrapped on the flange core 11 12. The flange core layer 11 is embedded in the flange main body 12, and the flange core layer 11 and the flange main body 12 form an integral body. The flange core layer 11 is formed by stamping the edge of the main body of the box through flanging process.

[0032] In the same structure, the cover body 3 also includes the main body of the box cover and the flange structure 1 arranged on the main body of the box cover. The flange structure 1 includes a flange core layer 11, which is cast and wrapped on the flange core layer 11. The flange main body 12 on the top, the flange core layer 11 is embedded in the flange main body 12, the flange core la...

Abstract

The invention relates to a flange structure of a box body or a cover body, an explosion-proof box and a manufacturing process. The flange structure comprises a flange core layer and a flange main body which is formed by pouring and arranged on the flange core layer in a wrapping mode, the flange core layer is embedded in the flange main body, and the flange core layer and the flange main body form a whole. According to the flange structure of the box body or the cover body, the explosion-proof box and the manufacturing process, the flange main body is poured on the flange core layer on the edge of the box body and the flange core layer on the edge of the cover body according to the actual size of the flange core layer on the edge of the box body and the actual size of the flange core layer on the edge of the cover body, so that the flange core layer is embedded in the flange main body, the flange core layer and the flange main body are combined to form the flange structure, the flange structure is processed and manufactured rapidly, the manufacturing efficiency is higher, the safe connection between the flange core layer and the flange main body is not influenced by the thickness, and the thicker the flange main body is, the tighter the cooperation between the flange core layer and the flange main body is, the stronger the rigidity is, and the better the explosion-proof effect is.

Description

technical field [0001] The invention relates to a flange structure of a box body or a cover body, an explosion-proof box and a manufacturing process. Background technique [0002] Explosion-proof boxes in the prior art include a box body and a cover set on the box body. Electronic products or electrical products that require explosion-proof treatment are arranged in the box body, and then the flange and cover on the box body Flange connection on the body, and a flameproof space is formed between the box body and the cover body. [0003] The flanges in the prior art need to meet a certain thickness requirement. The flanges on the explosion-proof box or cover are usually welded, and the flange is welded to the box or cover along the edge of the circle, and the production efficiency is extremely high. Low, so that the production cost is high, and once the welding effect is not good, there will be gaps, which will affect the explosion-proof effect and poor safety performance. ...
