What are the applications of laser pointer cutting technology in ships

The continuous development of shipbuilding technology has led to major changes in shipbuilding materials and ship design. The application of laser pointer technology in shipbuilding has its uniqueness, which is closely related to the processing and application characteristics of the ship itself and the characteristics of the laser pointer manufacturing system. So, what are the specific applications of lasers in ships?

In recent years, “precision shipbuilding” and “fast shipbuilding” have become the main trends in the development of the shipbuilding industry. Laser cutting technology has developed rapidly, accounting for more than 70% of the entire laser processing industry. The shipbuilding industry is mainly based on steel plate raw materials. The use of laser cutting plates can replace some punching processing methods that require the use of complex and large molds, greatly shortening the production cycle and reducing costs. After the laser cutting machine is used for blanking, the assembly margin is eliminated, the phenomenon of on-site repair and cutting is eliminated, the labor and material waste are reduced, the frame assembly speed is significantly accelerated, and the assembly quality is significantly improved.

At present, the cutting methods of hull plate parts in the shipbuilding industry mainly adopt flame cutting, plasma cutting, shearing processing and laser cutting. 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 ribs to ensure the assembly gap when the plasma is blanking the ribs, and the trimming is performed manually, resulting in uneven trimming quality. occur. Thereby reducing assembly workload, assembly cycle, material and labor costs.

The marine steel plate cut by laser has good cutting seam quality, good verticality of the cut surface, no slag, thin oxide layer, smooth surface, no secondary processing, direct welding, small thermal deformation, high curve cutting accuracy, and reduced coordination Working hours, to achieve barrier-free cutting of high-strength ship plates.

In the domestic shipbuilding industry, laser cutting does not occupy a dominant position. The main reasons include: ①green laser pointer cutting costs are higher than traditional cutting methods; ②Large-scale laser cutting equipment is not suitable for the manufacturing characteristics of the shipbuilding industry, such as on-site construction, block operation, The working environment is complicated, 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, which requires high workers and high costs. In view of the special requirements of the cutting machine for the ship’s outfitting work and the diversity of the processing shapes of the profiles used in the hull structure, the current situation of the industry is.

Multi-layer silo flat automatic loading and unloading laser cutting production line is an advanced automatic laser processing production line introduced by an industrial laser processing company in Dongguan to Teyu industrial chillers: multi-layer silo, saving floor space, automatic loading and unloading by robots , Improve production efficiency and reduce labor costs.

Because it is an automated operation, a special domain dual-temperature chiller that supports the communication protocol is selected as the cooling system. The special domain CWFL-2000 robot laser cutting machine chiller selected by the customer is specially designed for high-end automated laser production lines. It can realize the communication between the laser system and multiple chillers: monitor the working status of the chiller and modify the parameters of the dual-temperature chiller. When the working environment and working requirements of the chiller change, the user can modify the parameters of the chiller through the control program to adapt to the working environment and requirements.

Of course, it is also because the chiller of the special domain robot laser cutting machine has a dual-circulation refrigeration system: two independent temperature control systems, which separately cool the QBH connector (lens) and the body, which can effectively avoid the generation of condensed water. One machine has multiple uses and improves space. Utilization rate saves costs. In addition, the special dual-temperature chiller can also be equipped with a filter device to filter impurities such as ions in the water, which improves the convenience of users and really solves problems for users.
