The application of efficient equipment such as laser pipe cutting machines, pipe bending machines, and laser welding machines has greatly improved the production efficiency and precision of road guardrails and ensured the stability of their quality. This article will introduce the production process of road guardrails in detail, and focus on analyzing the key roles played by laser tube cutting machines, tube bending machines, and laser welding machines in this process.
1. Application of laser pipe cutting machine
Laser pipe cutting machine is a core equipment in the production of modern road guardrails, especially suitable for cutting processes with complex shapes. Compared with traditional mechanical cutting methods, laser pipe cutting machine has significant advantages such as high precision, high efficiency and low heat affected zone.
1.1 Working principle of laser pipe cutting machine
Laser pipe cutting machine irradiates the surface of the pipe with a high-power laser beam, and uses the high temperature of the laser to melt or evaporate the tube locally, so as to achieve precise cutting.
1.2 Advantages of laser pipe cutting machine
High precision and high efficiency: Laser pipe cutting machine can complete high-precision cutting in a short time, especially in the complex processing of pipes, which can avoid problems caused by human errors. Compared with traditional mechanical cutting, the processing speed of laser pipe cutting machine is much faster.
Strong adaptability: Laser pipe cutting machine is suitable for cutting tubes of various materials, whether it is steel tube, stainless steel tube or aluminum tube, it can achieve efficient cutting without damaging the surface of the tube.
Reduce material waste: The edges after laser pipe cutting machine are smooth and neat, which greatly reduces material waste and improves material utilization.
1.3 Application in road guardrail production
In the production of road guardrails, laser pipe cutting machine is usually used to cut steel pipes to the required length and shape, especially for some complex pipe cutting, such as T-type, cross-type, bevel and other special cutting processes, the advantages of laser tube cutting machine are particularly obvious.
In addition, laser pipe cutting machine can also be combined with automatic conveying system to further improve production efficiency and reduce manual intervention.
2. Use and technical requirements of pipe bending machine
The pipe bending process is an indispensable part of road guardrail manufacturing, especially when the curve design of the pipe needs to be realized in the production process, the role of pipe bending machine is particularly important.
The pipe bending machine applies pressure to the pipe to cause plastic deformation of the pipe to form the required curve.
2.1 Working principle of pipe bending machine
Pipe bending machines are generally divided into two categories: hydraulic pipe bending machines and CNC pipe bending machines. Hydraulic pipe bending machines generate pressure through the hydraulic system to deform the pipe along the direction of the bending die; CNC pipe bending machines use computer numerical control systems to accurately control the bending angle and radius of the pipe.
The main working process of the pipe bending machine is to put the pipe into the pipe bending machine fixture and bend the pipe along the predetermined trajectory to the required angle through mechanical or hydraulic action.
For some complex bending requirements, modern CNC pipe bending machines can be programmed to ensure the bending accuracy and consistency of each pipe.
2.2 Advantages of pipe bending machines
High precision: pipe bending machines can accurately control the bending angle and radius to ensure that each pipe meets the design requirements.
Strong adaptability: pipe bending machines can handle pipes of different materials and sizes to meet the design requirements of various road guardrails.
Improve production efficiency: CNC pipe bending machines can automatically complete the bending of pipes, reduce manual intervention, and improve production efficiency.
2.3 Application in the production of road guardrails
In the production process of road guardrails, pipe bending machines are often used to bend steel pipes to make the curved part of the guardrail. For example, urban traffic guardrails often need to adapt to different road surface shapes and turning requirements, and the application of pipe bending machines is particularly important at this time. Through precise bending, the pipe bending machine can ensure that the structure of the guardrail is stable and beautiful.
3. Use and process requirements of laser welding machines
Laser welding machines are a kind of high-efficiency welding equipment widely used in modern manufacturing. Especially in the welding process of road guardrails, laser welding machines can provide high-quality and high-efficiency welding effects.
Laser welding machines use high-power laser beams to heat the workpiece locally to a molten state, thereby achieving material connection.
3.1 Working principle of laser welding machine
Laser welding machines focus high-intensity laser beams on the welding part to quickly melt and fuse the material. It avoids problems such as overheating and deformation common in traditional welding methods.
3.2 Advantages of laser welding machines
High welding accuracy: laser welding machines can achieve precise welding line control, fine and uniform welding seams, and beautiful welding points.
Small heat-affected zone: Compared with traditional welding, the heat-affected zone of the laser welding machine is small, which can effectively prevent excessive deformation of the material.
Strong applicability: The laser welding machine can weld materials of different materials and thicknesses, and is particularly suitable for precision welding of thin-walled materials.
3.3 Application in the production of road guardrails
In the production process of road guardrails, laser welding machines are usually used to connect pipes and support columns and various parts of guardrails.
Laser welding machines can provide high-strength and smooth-surface welding effects to ensure the overall strength and appearance of guardrails. Especially when making large guardrails or guardrails with special shapes, the advantages of laser welding machines are particularly obvious.
Summary
The production of modern road guardrails is inseparable from the application of advanced equipment such as laser pipe cutting machines, pipe bending machines and laser welding machines. These equipment ensure the high-quality and efficient production of road guardrails by precisely controlling every link in the production process.
