With the development of science and technology, modern production lines for metal folding doors have widely introduced advanced equipment such as laser plate cutting machines, laser welding machines, laser pipe cutting machines, and pipe bending machines. In this article, we will analyze in detail the specific application of technical equipment such as laser plate cutting machines, laser pipe cutting machines, pipe bending machines, and laser welding machines in the production of metal folding doors.
1. Raw material preparation and pretreatment
The production of metal folding doors starts with the preparation of raw materials. Commonly used metal materials include steel plates, stainless steel plates, aluminum alloys, etc.
1.1 Material selection
Steel plates and stainless steel plates are often used in situations where higher strength and corrosion resistance are required, while aluminum alloys are suitable for doors that require lighter weight.
1.2 Material pretreatment
Before processing, the surface of the material must be pretreated by degreasing, rust removal, cleaning, etc. This link has an important impact on the processing accuracy and welding quality of metal folding doors.
2. Processing process of metal folding doors
The processing link of metal folding doors is the most critical part of its production process, involving many processes and equipment.
Modern production lines use high-precision equipment such as laser plate cutting machines, laser pipe cutting machines, and pipe bending machines, which greatly improves production efficiency and processing accuracy.
2.1 Application of laser plate cutting machines
The laser plate cutting machine is one of the core equipment in the production of metal folding doors, responsible for cutting metal plates. Laser cutting uses a high-power laser beam to precisely control the CNC system for cutting, punching, engraving and other operations. Its biggest advantage is:
High precision: The laser plate cutting machine can cut within the millimeter-level accuracy range, which can ensure that the size of the metal plate is very accurate and reduce the error of manual operation.
Fast cutting speed: The laser plate cutting machine can efficiently complete large-scale cutting tasks, significantly improving production efficiency.
Non-contact processing: The laser beam of the laser plate cutting machine does not directly contact the surface of the material, avoiding scratches, deformation and other problems caused by mechanical processing, and ensuring the smoothness and neatness of the cutting edge.
In the production of metal folding doors, laser plate cutting machines are generally used to cut door panels, door frame components and other components that require precise cutting.
2.1.1 Laser cutting process
The laser cutting process is controlled by a CNC system. The operator inputs the drawings to be cut through the CNC system, and the laser plate cutting machine starts automatic cutting according to these parameters.
2.2 Application of laser pipe cutting machine
For the frame and supporting structure of metal folding doors, laser pipe cutting machines are used to accurately cut metal tubes.
Laser pipe cutting machines can cut various pipes quickly and with high precision, especially for cutting complex shapes.
The supporting frame of metal folding doors often uses metal pipes, and laser pipe cutting machines can accurately cut and punch holes according to design requirements.
2.2.1 Working principle of laser pipe cutting machine
The laser pipe cutting machine irradiates the surface of metal pipes with laser beams. The strong energy of the laser beam quickly heats the metal to the melting point at the cutting point, thus forming precise cutting marks.
Unlike traditional mechanical pipe cutting, laser pipe cutting machine can complete high-precision pipe cutting, and can also complete operations such as punching and grooving during the cutting process, reducing the need for multiple processing.
2.3 Application of pipe bending machine
The frame part of metal folding doors usually requires some bent metal tubes, which requires a pipe bending machine.
The pipe bending machine accurately controls the angle and radius of the bending pipe through the CNC system, so that the pipe can be accurately bent according to the design requirements.
Modern pipe bending machines can bend pipes of various materials, including stainless steel, aluminum alloy and steel, and are especially suitable for the production of metal folding door frames.
2.3.1 Advantages of pipe bending machines
The advantage of modern pipe bending machines is that they can quickly and accurately complete complex pipe bending tasks.
CNC pipe bending machines can be programmed by computers to complete bending of multiple angles and radii at one time, with higher precision and efficiency.
2.4 Application of laser welding machine
In the production of metal folding doors, welding is a crucial link. Laser welding machine is used for welding door frames and other components. Its main advantages are:
High-precision welding: Laser welding machine can accurately control the welding area, the welding seam is fine and beautiful, and it is not easy to produce welding defects.
Small heat effect: Laser welding machine has a smaller heat-affected zone, which reduces the thermal damage and deformation of metal materials.
Fast welding speed: The welding speed of laser welding machine is fast, which is suitable for mass production and improves production efficiency.
2.4.1 Laser welding process
The working principle of laser welding machine is to locally heat the metal surface to a molten state through a high-intensity laser beam to form a welded joint.
In the production of metal folding doors, laser welding machine is mainly used to connect the various components of the frame to ensure that the welded joint is firm and beautiful.
Conclusion
The production process of metal folding doors is a precise system engineering. In this process, the application of laser cutting, laser welding, laser pipe cutting and pipe bending technology provides strong technical support for the high-quality production of metal folding doors. The future production of metal folding doors will be more intelligent, automated, and move towards a more efficient and precise direction.
