Application of laser cutting machine in shipbuilding industry
With the continuous development of shipbuilding manufacturing technology, shipbuilding materials and designs have also changed. Laser cutting machine has unique properties in shipbuilding manufacturing applications. This is also related to the actual application of the transmission itself. The characteristics of high-precision cutting and high plasticity of laser cutting machine are highly consistent with the shipbuilding industry. What are the applications of laser cutting machine in the shipbuilding industry?
The shipbuilding industry has high requirements for the accuracy of hull segment transfer, and the frame transfer gap must be controlled within 1mm. In the past, shipbuilding enterprises generally used plasma to cut ribs. In order to ensure the assembly gap, the ribs were set with a trimming allowance. This required manual trimming during on-site assembly. The trimming quality was uneven, and oxides remained in the cut seam. At the same time, the assembly workload was increased, and the assembly cycle increased, resulting in the extension of the entire segment construction cycle.
The application of high-power laser cutting machine perfectly solves this problem. Laser cutting machines can ensure high-precision production of workpieces. The error of workpieces produced by laser cutting machines is within ±0.05mm. Since high-power laser cutting machines can achieve high-speed cutting, their heat-affected zones are much smaller than those of plasma cutting machines, which effectively improves the problem of workpiece deformation.
In addition, since the laser cutting machine has a small workpiece processing error (within ±0.05mm), there is no need to reserve cutting surplus materials on the ribs, which not only saves materials and reduces the consumption of excess labor, but also saves time and shortens the manufacturing cycle of ships, which is more in line with the development trends of the two major industries of "precision shipbuilding" and "fast shipbuilding".
At present, my country's laser manufacturing technology continues to break through, and the level of laser manufacturing is also constantly improving. With the further localization and industrialization of lasers, the price of lasers is gradually reduced. At the same time, the application effect of laser cutting technology is gradually stable, which promotes the further popularization of laser cutting machines in the shipbuilding industry.
Compared with the traditional production methods (flame cutting, plasma cutting), laser cutting machines have the following advantages:
1. Low processing cost, fewer processing steps, and high efficiency
The traditional process generally includes 5 steps + 4 parts handling, while laser cutting can simplify the process to: plate entering the factory, laser cutting (laser cutting + laser beveling + laser drilling) 2 steps, which not only improves the processing speed and saves labor, but also greatly reduces the cost of shipbuilding.
In addition, laser cutting machines are very advantageous in dealing with medium and thick plate processing. The speed is faster than traditional plasma cutting, and as the power increases, the speed of cutting 10mm carbon steel plates will continue to increase. Similarly, as the power increases, the limit cutting thickness of carbon steel plates is also increasing.
2. Flexible and intelligent production is more suitable for the shipbuilding industry
The combination of laser cutting machines and robot machines can help users achieve intelligent and flexible production. The plate laser cutting machine is equipped with a hydraulic lifting auxiliary feeding mechanism and a lifting exchange platform to achieve flexible feeding and plate fine-tuning, fast cutting, and reduce non-production time. Combined with the high-intelligence CNC bus system, the laser cutting machine can realize the functions of changing the cutting process settings, real-time monitoring of the cutting status, and full detection and recording of cutting data parameters. It is an important help for engineers to continuously optimize the cutting process parameters and optimize the cutting effect of the workpiece.
3. Easy to maintain, saving time and effort
The light source of the fiber laser cutting machine is the laser beam transmitted through the optical fiber. Compared with the traditional mechanical optical path, this optical fiber transmission method is simpler, clear at a glance, and easy to maintain. Combined with the laser cutting machine distribution cabinet, it is safe, dust-proof, and anti-static, which greatly saves the time, energy and cost of maintenance.
