We are a professional manufacturer of bending machines with over 10 years of industry experience. Today, we would like to introduce you the application of bending machine in railroad transportation manufacturing:

Rail transportation equipment manufacturing is a field that requires high precision and quality. As the key equipment for sheet metal processing, bending machine plays an irreplaceable role in the production process of rail transportation vehicles. From the body structure to the interior components, the bending process runs through the entire manufacturing process, which directly affects the safety and reliability of the products.

1, Structural parts processing of car body

The body of a rail vehicle is mainly composed of aluminum alloy or stainless steel plates. Bending machines are used to process these large metal sheets, bending them into the required shapes and angles. Key components such as roof curved surfaces and side wall panels need to go through precise bending processes. CNC bending machines are able to ensure the consistency of large structural parts and ensure that the dimensional error of each part is controlled within the permissible range during mass production. In the manufacture of high-speed trains, the streamlined shape of the car body can not be separated from the high-precision bending process.

2, Bogie components production

Bogie is the core component of rail transportation vehicle, carrying the weight and running load of the whole vehicle. The bending machine is used to process all kinds of connecting plates and supporting parts of the bogie. These components are usually made of high-strength steel, and have strict requirements for bending accuracy and angular stability. The servo-electric bending machine can accurately control the bending process to avoid stress concentration within the material and ensure the fatigue life of the bogie. Meanwhile, the mold system of the bending machine can be changed quickly to adapt to the production needs of different types of bogies.

3, Manufacture of interior components

The interior decoration of rail transit vehicles includes many metal parts such as seat brackets, luggage racks, handrails, etc. These parts not only need to meet the functional requirements, but also take into account the aesthetics. These parts not only need to meet the functional requirements, but also take into account the aesthetics. Bending machine can process a variety of complex shapes of interior parts to meet the needs of personalized design. Especially CNC bending machine can realize continuous processing of multi-angle and multi-process, which greatly improves the production efficiency and consistency of interior parts. For standard parts that need to be mass-produced, the bending machine can ensure that the size of thousands of parts is completely uniform.

4, Electrical equipment case molding

Rail transit vehicles are equipped with a large number of electrical control equipment, and the metal cases of these equipment need to be molded by bending process. The dimensional accuracy and surface quality of electrical enclosures are very strict, and any deformation or scratches may affect the assembly quality. Modern bending machines are equipped with a laser inspection system that monitors the bending angle in real time to ensure the machining accuracy of each case. Meanwhile, the surface of the bending machine's mold is specially treated to avoid damaging the material surface during processing.

5, Maintenance and modification applications

In addition to newly built vehicles, bending machines also play an important role in the maintenance and modification of rail transportation equipment. Vehicle overhaul often need to replace local sheet metal parts, bending machine can be based on the actual measurement data to process the exact match of the replacement parts. In the vehicle modification, bending machine can quickly realize the design change requirements, greatly reducing the modification cycle. Portable bending machine can also be used in the maintenance site, for emergency maintenance to provide convenience.

6, Technology development requirements

With the progress of rail transportation technology, the bending process has put forward higher requirements. A new generation of bending machines need to have a stronger intelligent function, can automatically adapt to changes in the characteristics of different materials. Multi-axis bending technology can process more complex spatial surfaces to meet the needs of future train design. At the same time, energy saving and environmental protection have also become an important direction for the development of bending machines, reducing energy consumption and material waste in the production process.

From car body manufacturing to interior processing, bending machine through the various aspects of rail transportation equipment production. With the improvement of CNC technology and automation level, the application of bending process in the field of rail transportation will be more extensive and in-depth. Selecting suitable bending equipment and optimizing the processing technology is of great significance to improve the level of rail transportation manufacturing. In the future, intelligence and flexibility will become the main direction of the development of bending machines, providing stronger technical support for rail transportation manufacturing.
