Now "precision shipbuilding" and "rapid shipbuilding" have become the main trends in the development of the shipbuilding industry, and the technology of CNC fiber laser cutting machine has developed rapidly, accounting for more than 70% of the entire laser processing industry. The continuous development of shipbuilding technology has driven major changes in shipbuilding materials and ship design. The application of CNC fiber laser cutting machine technology in shipbuilding has its own uniqueness, which is closely related to the processing and application characteristics of the ship itself and the characteristics of the laser manufacturing system.
In the shipbuilding industry, the main application material is steel.
Steel is the most common industrial raw material, and we have many years of history and experience in CNC cutting of steel. However, ships are tools that carry life, and the requirements for their manufacturing materials are very high. A small skew or a small problem in the cutting of the sheet can lead to disaster for a whole boat. Therefore, laser cutting machines with no effect on raw materials, high precision and high safety factor will soon become the mainstream of the entire shipbuilding sheet metal manufacturing industry.
What laser cutting technology brings to the shipbuilding industry is metal processing with excellent production efficiency, excellent production quality, ultra-short production cycles and lower production costs.
The marine steel plate cut by laser has good cutting quality, good verticality of the cut surface, no slag, thin oxide layer, smooth surface, no need for secondary processing, can be directly welded, and has small thermal deformation, high curve cutting accuracy, and reduced coordination Man-hours to achieve barrier-free cutting of high-strength ship plates. This guarantees the quality of raw materials in the shipbuilding industry, thereby reducing the workload of assembly, assembly cycle, and waste of material and labor costs.
At present, the cutting machines for hull plate parts in the shipbuilding industry are mainly divided into CNC flame cutting machines, CNC plasma cutting machine, CNC shearing processing machine and CNC fiber laser cutting machines. Compared with laser cutting, other cutting methods have many shortcomings. In the field of shipbuilding, laser cutting avoids the need to set a trimming allowance on the rib in order to ensure the assembly gap when the plasma is blanking the rib, and trim it manually, resulting in uneven trimming quality. occur. Thereby reducing the assembly workload, assembly cycle, material and labor cost waste.
In the domestic shipbuilding industry, CNC fiber laser cutting machines do not occupy a dominant position. The main reasons include:
①The cost of laser cutting is higher than that of traditional cutting methods;
②The large-scale laser cutting equipment is not suitable for the manufacturing characteristics of the shipbuilding industry, such as on-site construction, segmented operations, complex working environment, etc.;
③There is no obvious advantage in cutting efficiency, especially for thick plate cutting in the shipbuilding industry;
④The maintenance of laser equipment is complicated and requires high workers and high costs. In view of the special requirements of the cutting machine for the ship outfitting work and the diversity of the processing shapes of the profiles used in the hull structure, it is the current situation of the industry.
With the improvement of laser processing system equipment technology, it is expected to gradually open up China's shipbuilding market space in the future, and the large-scale popularization of CNC fiber laser cutting machine, laser welding and laser cleaning and rust removal technology in the shipbuilding industry is also just around the corner.
