With the continuous improvement of industrial processing technology, laser cutting technology has also been developed and gradually evolved into the main laser processing technology in the sheet metal fabrication industry.
Laser cutting machines have been widely used in this field, which can ensure both cutting quality and efficiency.
In this article, we will give a brief introduction to the working principle of laser cutting machines and clarify their practical application paths.
1. Analysis of the Working Principle of Laser Cutting Machines
1.1 Laser Analysis
Laser cutting machines mainly use laser beams to cut materials. The lasers used in the machines are coherent light, which generally has outstanding monochromaticity and significant advantages in energy density.
Compared with ordinary light beams, laser beams have more prominent overall performance and can be applied on a large scale in different fields, such as laser treatment, drilling and welding, and sheet metal cutting.
Therefore, laser analysis technology has a very bright application prospect. When using laser cutting machines, it is required to fully utilize the density and heat advantages of the laser beams to carry out cutting operations to ensure that the sheet metal material can be sufficiently processed to cause vaporization and oxidation reactions.
At the same time, this processing process can also effectively ensure the cutting effect of the sheet metal material. Therefore, a comprehensive analysis of the working principle of the cutting machine is required.
1.2 Working Principle of Laser Cutting Machines
To use a laser cutting machine for cutting and processing elevator sheet metal structures, it is necessary to fully integrate the laser beam in the cutting machine equipment, so that it can be highly concentrated in the sheet metal material and play a role in a specific position.
This ensures that the laser is treated promptly when it is emitted and can immediately be converted into heat energy. The energy of the concentrated beam is generally relatively high, and the concentrated energy is significantly higher than can be accumulated in a single beam.
Therefore, the melting point of the material can often be reached in a short time, and the temperature will rapidly rise and gradually reach the boiling point of the material.
If the external temperature environment is high, the sheet metal material can be directly melted, causing vaporization and forming precise holes.
Once the hole device appears, it is necessary to make full use of the laser cutting machine equipment, play the guiding performance advantages of the equipment and carry out equipment management operations accordingly, so that the laser beam can obtain the specified path information and move freely along a fixed path. In this process, wherever the laser beam moves, a cut will be created on the surface, which accomplishes the laser cutting operation.
2. Application Examples of Laser Cutting Machines in Elevator Sheet Metal Fabrication
Taking a certain company as an example, as a professional elevator production enterprise, the laser cutting machines used in this company are imported from Italy and are L1Xe fiber laser cutting machines.
The generator power can reach 2kW, and the maximum thickness of the cut plate is 18 millimeters. The main purpose of introducing this equipment is to cut escalator, elevator door panels, and support plates.
It is necessary to make full use of the laser cutting machine equipment to promote the processing quality improvement of elevator support plates and fish-shaped plates in sheet metal fabrication.
Furthermore, because the cutting speed of a laser cutting machine is relatively fast, with no need for multiple clampings, it can achieve automatic edge-finding and thus shorten the processing cycle of the project, reduce the processing operation costs of the company, and shorten the R&D cycle of elevator products.
When using laser cutting machines for sheet metal fabrication, the materials used in the fish-shaped plate processing process often show an irregular distribution. If conventional machine tool machining cannot be completed with high quality, the application of laser cutting machines may be limited.
Therefore, it is necessary to make full use of laser cutting machine programming software, play the advantages of auxiliary rotary support and optimized material layout, and efficiently carry out workpiece processing to ensure high-quality elevator workpiece processing when using laser cutting machine equipment.
At the same time, corresponding steps can be simplified and the processing cycle can be reduced, which simplifies the installation difficulty of laser cutting machine equipment workpieces and continuously improves the processing accuracy level of workpieces.
In the elevator sheet metal fabrication process, mold design is usually carried out for the device.
This may significantly increase the processing cycle, and, due to the types and forms of molds, it may directly affect the processing quality and efficiency of workpieces, rendering them of no use and leading to serious economic losses and time consumption.
Through the use of laser cutting machine equipment, processing without using molds can fully save mold design and production links, thus reducing the processing time and costs of workpieces and enabling enterprises to comprehensively improve their new product development capabilities and market competitiveness.
3. Analysis of the Application of Laser Cutting Machines in Elevator Sheet Metal Fabrication
Generally, in elevator sheet metal fabrication, companies commonly use fiber laser cutting machines. These machines usually have good performance and can achieve high-quality cutting operations when used properly.
Laser cutting machines are also used in structures such as elevator support frames, escalator fish plates, and elevator door panels to obtain good cutting results.
In general, mold design is necessary to achieve good workpiece design results when carrying out elevator sheet metal work, and this mold design work is often very complicated and may require a large economic cost in the actual design phase.
In this context, most companies often use laser cutting machine equipment to perform elevator sheet metal fabrication, which does not require mold restrictions and is flexible in both cutting range and cutting form.
Thus, the processing cycle can be shortened, construction costs can be saved, and the risk of material waste can be reduced.
In addition, it is necessary to fully use laser cutting machine equipment in the processing of elevator support plate workpieces and fish-shaped plate structures to achieve good processing results and ensure high-quality processing results by comprehensively using programming software and material layout functions, with a premise of reducing processing costs.
Compared with traditional sheet metal cutting technology, laser cutting technology has significant application advantages, specifically: First, the cutting speed advantage of this technology is obvious.
It requires the laser beam to be irradiated onto the material surface to induce rapid melting and gasification reactions, and the cutting operation can be completed in a generally fast speed, usually only taking a few microseconds to reach the material melting and boiling point and to complete subsequent perforation and cutting operations. Second, the cutting quality of laser cutting machines is relatively high.
Utilizing the laser beam form, cutting and processing operations can be realized in a short time, with a relatively fast cutting speed, and the cutting quality is relatively high.
The operation speed of the equipment generally does not affect its cutting quality, and the cut slit in the sheet metal material is generally small, making the cut surface position smooth and uniform, with very few problems such as cut surface concavity or unevenness, with outstanding overall cutting quality advantages.
Third, during cutting processing, the material is not significantly affected. When using traditional cutting processes, the material’s overall application may be limited due to the influence of the cutting tool nature, which in turn affects the material’s overall performance.
However, the use of laser cutting machines for cutting does not cause too much negative impact on the material. Fourth, the cutting operations are relatively flexible, and the cutting range of the device is flexible and can fully adapt to the requirements of different shaped cutting machines, thus reducing the material requirements for cutting.
For most materials, laser equipment can be used for cutting, and it does not significantly affect the shape of the cut device, which can fully meet the requirements of contemporary numerical control technology.
At the same time, when using this equipment, it can show good cutting speed advantages, and usually, no polishing treatment is required to produce the required finished tools, which does not affect the tool structure and quality.
It can be determined that laser cutting technology has a certain cost advantage with excellent technological and economic benefits. If the company requires high efficiency in technical management, laser cutting technology can be used appropriately.
In general, laser cutting machine equipment is a relatively excellent choice, and the technology has been widely used in different social fields and is gradually becoming more mature, with good application prospects.
In conclusion, the application advantages of using laser cutting machines in elevator sheet metal fabrication are relatively prominent.
By using this technology, processing efficiency can be comprehensively improved, and the limitations of molds can be overcome, thus reducing the processing cost of enterprises. The rotary support function of the device can be fully utilized, and material processing can be carried out accordingly, allowing for the full satisfaction of irregular material processing needs and aiming for more substantial economic benefits while reducing the impact on other operations.
Therefore, relevant practitioners need to actively explore laser technology and laser cutting machine equipment, promote their application, and better serve society, thus promoting social development.
