In the process of making metal folding tables, there are multiple key process links involved, among which the application of laser pipe cutting machines, pipe bending machines and laser welding machines greatly improves production efficiency and product quality. This article will focus on the role played by laser pipe cutting machines, pipe bending machines and laser welding machines in this process.
1. Laser pipe cutting machine: precise cutting of metal tubes
Laser pipe cutting machines are important equipment in the current metal processing field, especially when producing metal frame products (such as the bracket of the folding table), which can provide high-precision cutting effects.
The laser pipe cutting machine uses the high temperature of the laser beam to make the metal tube melt and evaporate rapidly during the cutting process, thereby completing precise cutting.
1.1 Working principle of laser pipe cutting machine
The working principle of laser pipe cutting machine is to focus a high-power laser beam on the surface of the metal pipe, heat the metal to the melting point through the high temperature of the laser, and then achieve cutting.
1.2 Advantages of laser pipe cutting machine
1. High-precision cutting: The laser pipe cutting machine can provide high-precision cutting effects, and the error can be controlled within millimeters or even smaller, which is suitable for the production of complex-shaped metal parts.
2. High degree of automation: The laser pipe cutting machine is usually equipped with an automatic loading and unloading system, which can greatly improve production efficiency, reduce manual intervention, and reduce production costs.
3. No tool wear: Unlike traditional mechanical cutting methods, the laser pipe cutting machine does not have the problem of tool wear, so after long-term operation, it can still maintain a high cutting accuracy.
4. Adapt to a variety of materials: The laser pipe cutting machine can not only cut steel pipes, but also cut stainless steel, aluminum alloy, copper and other metal materials.
1.3 Application of laser pipe cutting machine in the production of folding table
In the production process of metal folding table, laser pipe cutting machine is mainly used to cut the tubes of frame structure. For example, the four supporting legs, beams and metal parts of folding mechanism of the table need to be cut by laser pipe cutting machine. Through laser pipe cutting machine, various shapes of pipes can be accurately cut according to the design drawings, and the cuts are smooth, which reduces the difficulty of subsequent processing.
2. Pipe bending machine: precise forming of metal tubes
In the production of metal folding table, pipe bending machine is another indispensable equipment. Pipe bending machine can accurately bend metal tubes into the required shape by controlling the stress of pipes during bending.
2.1 Working principle of pipe bending machine
The pipe bending machine bends metal pipes through a set of dies and roller devices. Modern pipe bending machines are usually equipped with CNC systems, which can be operated automatically according to CNC programs to ensure the accuracy of bending angles.
2.2 Advantages of pipe bending machine
1. High-precision forming: Pipe bending machine can accurately bend metal pipes without cracks or deformation.
2. Adapt to a variety of pipe materials: Different pipe materials, diameters and thicknesses can be processed by adjusting the parameters of the pipe bending machine.
3. Improve production efficiency: Modern CNC pipe bending machines can process automatically, which not only improves production efficiency but also reduces the need for manual intervention.
2.3 Application of pipe bending machines in folding table production
The bracket of the metal folding table requires multiple bending parts to ensure that the table is both stable and easy to fold. The pipe bending machine plays an important role in this process.
Through the pipe bending machine, the production line can quickly bend the pipe into the required shape, such as the bending part of the table leg, the connecting part of the folding structure, etc.
3. Laser welding machine: precision connection of metal parts
After completing the cutting and bending of the metal pipe, the next step is to assemble the various components. The laser welding machine plays a vital role in this process.
3.1 Working principle of laser welding machine
The laser welding machine generates high temperature at the metal joint by focusing the laser beam to melt the metal locally. As the cooling process proceeds, the molten metal solidifies rapidly to form a strong welding point.
The laser welding process is very precise and can achieve micron-level positioning, so it is particularly suitable for welding work that requires high precision.
3.2 Advantages of laser welding machine
1. High welding quality: the weld is flat, without pores, and the welding strength is high.
2. Small heat-affected zone: The heating zone of laser welding is very small, avoiding deformation caused by overheating.
3. High degree of automation: Laser welding reduces the error of manual operation and improves production efficiency.
4. Strong adaptability: Laser welding is not only suitable for metal materials such as stainless steel and aluminum alloy, but also can perform fine welding on thin-walled materials.
3.3 Application of laser welding machine in folding table production
In the production of metal folding tables, laser welding machines are mainly used for connecting various parts of the frame. Laser welding technology can achieve high-precision welding, ensuring that each joint is firm and intact, and the appearance is smooth.
In addition, the high precision and low heat impact of laser welding also reduce the need for subsequent grinding and finishing, further improving production efficiency and product quality.
4. Summary
With the continuous development of manufacturing technology, the combination of laser technology, CNC technology and automation equipment will further promote the progress of the metal furniture manufacturing industry, continuously improve product quality and production efficiency, and promote the emergence of more innovative designs.
