Embodiment 1

[0027] as attached Figure 1-3 As shown, a kind of IIC level welded explosion-proof box body, comprises box body 1, the loam cake 2 that covers is arranged on box body 1, box body 1 comprises enclosure body 11, bottom plate 12 that is fixed on enclosure body 11 bottom, is fixed on enclosure body 1. A top plate 13 with a hole in the middle of the upper part of the body 11.

[0028] Surrounding body 11 is to use two pieces of metal plates to bend and put together, welded at seam to form, and surrounding body 11 comprises four plane walls 111, is positioned at every adjacent two plane walls 111 between four planes. The corner wall 112 , the corner wall 112 is located at the corner, and its area is obviously smaller than the plane wall 111 . The base plate 12 is quadrilateral, and the lower edge of the surrounding body 11 is welded with the base plate 12 to form a whole, and the corners of the base plate 12 protrude outwards from the lower edge of the corner wall 112 .

[0029] ...

Embodiment 2

[0038] as attached Figure 4 , 5 As shown, the difference between the second embodiment and the first embodiment is that the upper cover 2 is hinged.

[0039] The upper cover 2 is connected to the box body 1 through two hinges, and the two hinges are located on the outer sides of two adjacent corner walls 112 and above the corresponding two corners of the bottom plate 12 .

[0040] Specifically, the upper cover 2 has a stop cover flange 22, and the shape of the top plate 13 corresponds to the upper side of the enclosure 11 and is welded together to form a whole. The opening of the top plate 13 is welded with a ring to match the stop cover flange 22 The flange 15 of the spigot body extends outward from the welding of the two corner walls 112 to form two hinge installation angles 131, and the hinge installation angle 131 is fixed with a hinge seat 161, and the two hinge seats 161 slide along the up and down directions respectively. The hinge rods 162 are connected, and the upp...

Abstract

The invention discloses an IIC-grade welded explosion-proof box and a manufacturing technology of a box body of the IIC-grade welded explosion-proof box. The IIC-grade welded explosion-proof box comprises the box body and an upper cover, the box body comprises an enclosing body, a bottom plate and a top plate fixed to the upper portion of the enclosing body and provided with a hole formed in the middle, and the enclosing body is formed by welding metal plates at a seam after the metal plates are bent, and comprises a plurality of plane walls and a plurality of corner walls located between every two adjacent plane walls; and the bottom plate is a polygon with the number of edges being equal to that of the plane walls, the lower edge part of the enclosing body is welded to the bottom plate to form a whole, and the corner parts of the bottom plate extend outwards from the lower edge parts of the corner walls. The enclosing body is a polygonal enclosing body formed by the plane walls and the corner walls located at the corner parts, the pressure resistant effect is good, using is safer, and the size of an exterior package is greatly reduced secondly, but the practical size cannot be affected; and a manufacturing mode of shape bending and then tailor-welding is adopted, the size dimension can be manufactured freely according to needs of customers, compared with a mould-opening manufacturing technology, the flexibility is higher, and the production cost is greatly reduced.

Description

technical field [0001] The invention relates to a manufacturing process of a class IIC welding explosion-proof box body and the box body. Background technique [0002] The IIC level welded explosion-proof box in the prior art includes a box body and an upper cover set on the box body. The box body includes an enclosure, a bottom plate fixed to the lower part of the enclosure, and a Top plate with a hole in the upper part and a hole in the middle. Holes are opened on the explosion-proof box for making explosion-proof distribution boxes, explosion-proof control boxes and the like. Explosion-proof enclosures are usually square and upright, as shown in the open document of patent publication number CN301483532S, with a roughly square enclosure, and the square enclosure is fixed on the corresponding bottom plate and top plate on the upper and lower sides. The explosion-proof box is used to install on the wall and other parts, so the installation feet are indispensable. Usually,...
