Hereinafter, a manufacturing process of the dry enclosure frame according to the present invention will be described. In this regard, FIG. 7 is a development view for explaining a manufacturing process of the dry enclosure frame.

Referring to Figure 7, the border of the side edge inner plate (14, 24) and the folding plate (36, 37, 46, 47, 56, 57) and the side edge inner plate (14, 24) and the side edge front plate (13) , 23) is the boundary of the first bent portion (C1), the side edge front plate (13, 23) and the side edge outer plate (12, 22) and the side edge outer plate (12, 22) and the outer support plate (11) , 21) is the second bent portion D1, the boundary between the upper border front plate 33 and the upper folding plates 36 and 37 and the lower border front plate 43 and the lower folding plates 46 and 47. The boundary lines each form a third bent portion G1.

Referring to this, the process for manufacturing the dry enclosure frame will be described. In the same way as in the wet enclosure frame manufacturing process described above, first, after folding a sheet of sheet material, the central portion (A1) forming the inner accommodation space of the enclosure frame is punched Remove and cut the outer portion B1 to cut the plate (step a). In this process, punching and cutting processes are performed simultaneously.

Then, in the plate material cut as described above, after sequentially bending the first bent part (C1), the second bent part (D1) and the third bent part (G1), the side edge inner plates (14, 24) And the folding line (F1) consisting of the boundary of the folding plate (36, 37, 46, 47, 56, 57) is folded to form a side edge by interviewing the inner side plate and the folding plate of the side edge (step c) . At this time, each of the side edge inner support plates 15 and 25 is hammed by the incision H cut in advance, so that it maintains a right angle to the folding surface without a separate bending process.

In addition, the process of interviewing the side edge inner plates 14 and 24 and the folding plates 36, 37, 46, 47, 56, and 57 may be performed in the same manner as in the case of the wet enclosure frame described above. On the other hand, in the present invention, the square folding and the reverse folding are basically based on right angle folding of 90 °, but the side edge inner plate and the folding plate are completely folded to face each other. Therefore, while the side edge inner plates and the folding plates are face-to-face, the side edge inner plates 14 and 24 and the side edge inner support plates 15 and 25 are reverse-folded at right angles.

According to the present invention, the bending process of the first bent part (C1) and the second bent part (C2) is characterized in that it is performed using a molding mold having a two-step bending surface.

In addition, according to the present invention, by forming the two-step bending surface obliquely in the inclined direction as described above, there is an effect of minimizing the working space as the bent member is disposed in the 45 ° direction of the molding mold after molding. In addition, it is possible to minimize the vertical movement distance between the upper mold and the lower mold for bending, thereby reducing the installation space of the equipment.

In this case, the first bent portion C1 is bent on the first two-stage bent surface, and then the second bent portion D1 is bent on the second two-stage bent surface. At this time, the second bent portion D1 may also be bent on the first two-step bending surface. In this case, the upper and lower surfaces of the plate material are turned over to perform the bending process.

In addition, contrary to the forming mold, the forming mold is rotated counterclockwise with the first two-step bending surface ' It is formed in the form of ', and the second 2nd cut surface is rotated clockwise ' ' can be formed.

In this case, the first bent portion C1 is bent on the second two-stage bent surface, and then the second bent portion D1 is bent on the first two-stage bent surface. At this time, the second bending line D1 may be bent on the second two-step bending surface. In this case, the upper and lower surfaces of the plate material are turned over to perform the bending process.

As described above, when the side edges 10 and 20 are formed by the bending process, a bending process for forming the upper edge 30 and the lower edge 40 is then performed (step e).

To this end, referring to FIG. 7 again, the upper edge 30 of the enclosure frame includes the boundary line between the upper edge outer support plate 31 and the outer plate 32 and the upper edge outer plate 32 and the front plate 33.

Accordingly, the upper edge 30 and the lower edge 40 are formed by sequentially bending the bent parts E1 , E2 , E3 , and E4 . At this time, the upper edge 30 and the lower edge 40, as described in the manufacturing process of the side edges 10 and 20, each of the upper and lower bent portions E1 and E3 formed on the upper and lower edges and the lower bent The parts E2 and E4 are formed by a single press process using a forming mold having a double-ended curved surface. 'and' ' It is formed by sequentially bending the shape.
