S1: the sealed bulkhead 1 is selected and the shape of the temporary fabrication hole 2 in the sealed bulkhead 1 is determined.
specifically, the sealed bulkhead 1 selected in the present embodiment is numbered FR29, and a sealed space is formed in the sealed bulkhead 1. In this embodiment, the shape of the temporary fabrication hole 2 is determined to be a waist shape, and it should be noted that, in order to facilitate the access of a constructor to the temporary fabrication hole 2, in this embodiment, the orientation of the waist shape length needs to be considered when determining the temporary fabrication hole 2, that is, it should be ensured that the waist shape length direction of the temporary fabrication hole 2 in the using process is in the vertical direction.
S2: a circle of inner ring wire 202 and a circle of outer ring wire 203 are planned on the sealed bulkhead 1 according to the determined shape of the temporary fabrication hole 2.
Specifically, since the temporary process holes 2 defined in this embodiment are waist-shaped, the shapes of the inner ring line 202 and the outer ring line 203 in this embodiment are also waist-shaped, the inner ring line 202 in this embodiment is located inside the outer ring line 203, the shapes of the inner ring line 202 and the outer ring line 203 are similar, and the difference between the two is only the size difference. In this embodiment, the inner ring line 202 and the outer ring line 203 are concentrically arranged, and the inner ring line 202 and the outer ring line 203 are integrally formed in an elliptical ring shape. In this embodiment, the vertical distance between the inner ring line 202 and the outer ring line 203 is 8mm, and in other embodiments, the vertical distance between the inner ring line 202 and the outer ring line 203 may be any value between 5mm and 15mm, for example, 5mm, 6mm, 7mm, 9mm, 11mm, 12mm, 14mm, 15mm, and the like.
S3: more than two bridging connections 201 are determined between the inner ring line 202 and the outer ring line 203, each bridging connection 201 is arranged at intervals along the outer peripheral side of the inner ring line 202, and the inner ring line 202, the outer ring line 203 and any two adjacent bridging connections 201 surround a cutting part 204 on the sealed bulkhead 1.
specifically, in the present embodiment, two gap bridge connections 201 are provided, two gap bridge connections 201 are symmetrically provided on two sides of the inner ring line 202, and since each cutting portion 204 needs to be cut, each gap bridge connection 201 in the present embodiment is a portion left behind in the sealed bulkhead 1 connected between the inner ring line 202 and the outer ring line 203 after cutting. As shown in particular in figure 3. In other embodiments, the bridge connections 201 between the inner loop 202 and the outer loop 203 may be provided with three, four, five, etc., and these bridge connections 201 are spaced along the outer circumference of the inner loop 202. In this embodiment, in order to ensure the connection strength of the bridge connection 201, the width of the bridge connection 201 is 20mm, and in other embodiments, the width of the bridge connection 201 may be any value between 10mm and 40mm, for example, 10mm, 15mm, 25mm, 30mm, 40mm, and the like. Setting the width of the bridge connection 201 within this range is based on the consideration of the connection strength, and it should be ensured that the bridge connection 201 is easily cut and ground at a later stage. It should be noted that the width of the bridge connection 201 in this embodiment is the distance between two adjacent cutting portions 204.
S4: each cutting portion 204 is cut by a hole-forming device.
Specifically, since there are two bridge connections 201 in the present embodiment, there are two corresponding cutting portions 204 separated by each bridge connection 201, and specifically, as shown in fig. 3, in the present embodiment, the two cutting portions 204 are both U-shaped and the U-shaped openings are disposed oppositely. In this embodiment, the hole forming device is a numerical control device (numerical control machine), and in other embodiments, the hole forming device may be a common machining tool.

Specifically, the sealed bulkhead 1 of the present embodiment needs to be installed and fixed according to a normal installation manner after being processed, when a corresponding sealed cabin needs to be accessed, each bridge connection 201 needs to be cut first, after each bridge connection 201 is cut, the remaining portion of the sealed bulkhead 1 connected to the inner side of each bridge connection 201 can be removed, at this time, each outer ring line 203 separated by each bridge connection 201 is connected into a complete ring, and the through hole located at the inner side of the outer ring line 203 is the temporary fabrication hole 2.
S6: the bridging connection 201 remnants left on the sealed bulkhead 1 after cutting are ground to form the temporary tooling holes 2.
Specifically, since each bridge connection 201 has a part of residues after cutting, the residues may cause the local part of the temporary fabrication hole 2 to be relatively sharp and may be easily scratched when the constructor passes through the temporary fabrication hole 2, and therefore, after each bridge connection 201 is cut, the sharp residues need to be polished to be flat by a polishing tool.
S7: and processing the corresponding sealing plate according to the shape of the determined temporary fabrication hole 2.
Specifically, in this embodiment, because the inside construction of the sealed cabin is finished, the temporary fabrication holes 2 need to be sealed and plugged, and in order to facilitate later-stage welding and plugging, in this embodiment, after the gap bridge connection 201 is processed, sealing plates corresponding to the temporary fabrication holes 2 need to be processed according to the shape and size of the temporary fabrication holes 2. The edge of the sealing plate needs to be subjected to welding groove processing in the processing process of the sealing plate, the welding groove processing is performed only on one side of the sealing plate in the embodiment, the angle of the welding groove is 45 degrees, and the angle of the welding groove can be any value between 30 degrees and 60 degrees in other embodiments, such as 30 degrees, 35 degrees, 40 degrees, 50 degrees, 55 degrees and 60 degrees.
s8: after the construction in the sealed cabin is finished, the temporary fabrication holes 2 are welded and sealed back through the sealing plates.
Specifically, after the construction is completed in the sealed cabin, the sealing plate is welded and fixed at the temporary fabrication hole 2 by arc welding in the embodiment.
To sum up, the embodiment of the invention provides a hole opening operation method for a temporary process hole 2 of a ship bulkhead, which greatly reduces the operation intensity of a subsequent hole opening process and a subsequent sealing process, simplifies the field operation process, improves the construction efficiency, and eliminates the safety risk of the field operation to a certain extent. In addition, the standardized and unified processing of the hole patterns is realized, the automatic and streamlined production process of the temporary fabrication hole 2 is improved to a certain extent, and the hole patterns of the temporary fabrication hole 2 are attractive and low in manufacturing cost.
