[0032] Hull structure parts coding rules: Small molding: the process of combining two or more parts of smaller volume together; Large forming: the process of combining two or more parts of larger volume; Secondary assembly: the process of welding parts or components together; Mid-assembly: The process of assembling parts or components by welding them together in sections in a certain area of ​​the hull.

[0033] By adopting the above technical solutions: After the hull structure parts are extracted from the 3D modeling software, they are CAD part blocks with the hull structure part code as the block name. According to the coding rules, the CAD part blocks are rearranged through program processing and arranged according to different middle assemblies. Different middle assemblies are then arranged according to secondary middle assemblies, small molding, and large molding. When cutting and nesting, they are nested in different lanes according to the rearranged parts. The production is distributed according to the assembly and other construction processes according to the nesting diagram of the nesting lanes. After nesting by this method, the rhythmic production is well met, the poor circulation of the cutting site is reduced, the turnover efficiency of the surplus materials is reduced, the assembly efficiency is improved, the economic benefits are obvious, and the cost is saved.

[0034] Example 2: Based on Example 1, this example introduces the specific structure of the blanking mechanism 2 in a hull structure parts cutting device. The fourth adjustment seat 21, the fifth adjustment seat 22, the sixth adjustment seat 23 and the seventh adjustment seat 24 all include a U-shaped seat, a motor, a screw rod and a sliding rod, and the output shaft of the motor is fixedly connected to the screw rod through a coupling, and the sliding rod is located on one side of the screw rod.

[0035] In some examples, the first blanking assembly 25 and the second blanking assembly 26 both include a second connecting seat 251, a second electric cylinder 252 is installed on the second connecting seat 251, one end of the push rod of the second electric cylinder 252 is fixedly connected to the driving seat 253, a rotating motor 254 is installed on the driving seat 253, the output shaft of the rotating motor 254 is fixedly connected to the second vacuum pump assembly 255, and the second vacuum pump assembly 255 is connected to the second suction cup 256.

[0036] When the second vacuum pump assembly 255 is working, the second suction cup 256 generates a negative pressure adsorption force, which relies on the negative pressure adsorption force to adsorb and fix the cut material, thereby picking up the cut material and separating the cut material from the remaining material. When the second electric cylinder 252 is working, it drives the driving seat 253 at one end thereof to move axially to adjust the height position of the second suction cup 256. After the second suction cup 256 reaches the specified position, it first moves up to pick up the cut material, then drives the cut material to move down, and finally moves the cut material out of the cutting area under the drive of the adjustment seat. When the rotating motor 254 is working, it drives the second vacuum pump assembly 255 at one end thereof to rotate. The second vacuum pump assembly 255 drives the second suction cup 256 to rotate. After the blanking assembly moves the cut material out of the cutting area, it flips the blanking.

[0037] In some examples, the second connecting seat 251 of the first blanking assembly 25 is sleeved on the screw rod and the sliding rod of the sixth adjustment seat 23, and the second connecting seat 251 of the first blanking assembly 25 is slidingly connected to the sliding rod of the sixth adjustment seat 23.

[0038] When the motor of the fourth adjustment seat 21 is working, it drives the screw at one end thereof to rotate, thereby driving the sixth adjustment seat 23 to slide along the sliding rod of the fourth adjustment seat 21, thereby adjusting the position of the first blanking component 25 in the Y-axis direction. When the motor of the sixth adjustment seat 23 is working, it drives the screw at one end thereof to rotate, thereby driving the second connecting seat 251 of the first blanking component 25 to slide along the sliding rod of the sixth adjustment seat 23, thereby adjusting the position of the first blanking component 25 in the X-axis direction.

[0039] In some examples, the second connecting seat 251 of the second blanking assembly 26 is sleeved on the screw rod and the sliding rod of the seventh adjustment seat 24, and the second connecting seat 251 of the second blanking assembly 26 is slidingly connected to the sliding rod of the seventh adjustment seat 24.

[0040] When the motor of the fifth adjustment seat 22 is working, it drives the screw at one end thereof to rotate, thereby driving the seventh adjustment seat 24 to slide along the sliding rod of the fifth adjustment seat 22, thereby adjusting the position of the second blanking component 26 in the Y-axis direction. When the motor of the seventh adjustment seat 24 is working, it drives the screw at one end thereof to rotate, thereby driving the second connecting seat 251 of the second blanking component 26 to slide along the sliding rod of the seventh adjustment seat 24, thereby adjusting the position of the second blanking component 26 in the X-axis direction.

[0041] The first blanking component 25 blanks the cut material from one side of the sheet 4 , and the second blanking component 26 blanks the cut material from the other side of the sheet 4 , thereby achieving cutting and blanking at the same time and improving processing efficiency.

[0042] In some examples, the fourth adjustment seat 21 and the sixth adjustment seat 23 are perpendicular to each other, and the fifth adjustment seat 22 and the seventh adjustment seat 24 are perpendicular to each other.

[0043] By adopting the above technical solutions: When cutting the material sheet 4, the lower part of the material sheet 4 is not contact-blocked. The cutting material in the area on one side of the material sheet 4 is cut through the first cutting component 25, and the cutting material in the area on the other side of the material sheet 4 is cut through the second cutting component 26. After the second suction cup 256 of the cutting component reaches the specified position, it first moves up to pick up the cutting material, then drives the cutting material to move down, and finally moves the cutting material out of the cutting area under the drive of the adjusting seat, and then flips the cutting. The cutting and cutting can be achieved by the cutting components on both sides, which improves the processing efficiency, reduces the accumulation of hull parts, and improves the efficiency of hull parts sorting.

According to the coding rules, the CAD part blocks are rearranged through program processing and arranged according to different mid-assemblies. Different mid-assemblies are then arranged according to secondary mid-assemblies, small molding, and large molding. When cutting and nesting, the rearranged parts are nested in different lanes.
