In the 21st century, advancements in automation technology have strongly propelled the development of the machinery manufacturing industry. One of the most notable applications of automation technology in the sheet metal processing industry is the automatic panel bending center. This is a modern solution for the process of bending, pressing, and folding sheet metal.

I. INTRODUCTION TO AUTOMATIC BENDING AND FOLDING CENTERS.

A. Definition of automatic bending and folding centers:

Automatic bending and folding centers are designed to process thin sheet metal. With the support of modern CNC technology, these machines can operate accurately, quickly, and efficiently. This helps optimize mass production processes in the sheet metal processing industry.

B. Development of automatic bending and cutting centers worldwide:

This equipment has been widely applied due to its ability to improve productivity and product quality. Some well-known equipment providers include: Salvagnini, Prima Power from Italy, Trumpf from Germany, Amada from Japan, LVD Group from Belgium, and Dardontech from China. However, in Vietnam, this equipment is still in a new phase and not yet widely known.

C. The importance of automatic bending and folding centers in the modern sheet metal manufacturing and processing industry:

The application of automation technology can bring many benefits to the sheet metal processing industry. It helps increase productivity and product accuracy. With these advantages, automatic bending and folding centers become an important factor in enhancing competitiveness for factories operating in the field of sheet metal processing.

II. OPERATING MECHANISM OF AUTOMATIC BENDING AND FOLDING CENTERS.

A. Structure and operating principles of automatic bending and folding centers:

A.1 Structure

Automatic bending and folding centers are composed of 3 basic components, including:

+ Upper and lower bending blade system:

Controlled by linear interpolation and synchronized with other parts.

+ Automatic blankholder:

Works simultaneously with the upper and lower blades to bend and clamp the sheet accurately and effectively. It adjusts the tool length according to the size of the part being produced in the cycle to minimize dead time. The tool profile allows inward bending up to 45 degrees.
+ Counterblade:

Responsible for clamping the sheet throughout the bending, pressing, and folding process.

A.2 Operating principle:

The operating principle of automatic bending and folding centers is based on CNC control technology with synchronized interpolation of axes. The machine can identify, bend, and fold sheet metal accurately based on pre-programmed parameters.

The machine uses CNC control technology, feedback sensors, and 3D simulation software to automate the bending, folding, and pressing process. This ensures that all sheet metal parts are processed accurately and consistently.

B. Outstanding features of automatic bending and folding centers:

The features of the equipment include the ability to press, fold, and bend sheet metal with high precision and product uniformity. The machine can also operate 24/7, increasing productivity and minimizing labor costs.

In addition, automatic bending and folding centers can also integrate with other production systems in the factory, such as workpiece loading and unloading robots, monitoring and product counting systems. This allows for complete automation of the production process.

C. Performance comparison between automatic bending and folding centers and manual bending and folding:

Compared to manual processing methods, automation offers many superior advantages. The machine can operate continuously without an operator. Moreover, it minimizes labor, thereby significantly increasing production output. Therefore, using this equipment not only helps save labor costs but also improves product quality.

III. BENEFITS OF APPLYING AUTOMATIC BENDING AND CUTTING CENTERS IN SHEET METAL MANUFACTURING AND PROCESSING.

A. Increase productivity and production efficiency:

The use of this equipment in the production process helps improve productivity and work efficiency. The machine can operate with minimal labor and enhance production capacity.

B. Minimize errors and risks in the bending and cutting process:

Automatic bending and folding centers also help minimize errors and risks in the production process. By using CNC interpolation technology synchronized between axes, the machine can cut and bend sheet metal with high precision, reducing the risk of human error.

C. Save costs and resources in the long run:

Although the initial investment in this equipment can be expensive, in the long run, the machine will help save costs significantly. Because the machine can operate continuously, labor costs can be reduced. At the same time, minimizing production errors also helps save costs for repair and re-production.

D. Practical applications
For mass production with a variety of products and designs, the machine can handle many different types of products, from medical devices, electrical cabinets, household appliances, kitchen equipment, to shelves, server cabinets, and steel doors.

IV. POTENTIAL AND CHALLENGES OF APPLYING AUTOMATIC BENDING AND CUTTING CENTERS IN VIETNAM

A. Assessment of the automation machinery market in Vietnam:

Vietnam is witnessing strong growth in the manufacturing industry. At the same time, the demand for automation machinery is also increasing. However, the use of this equipment is still a new concept for many businesses and workers in Vietnam. Therefore, this is an opportunity for businesses to approach and make breakthroughs in production and business.

B. Challenges and opportunities when applying automatic bending and cutting centers:

The biggest challenge when applying automatic bending and folding machines in Vietnam may be the high initial investment cost. However, with the strong growth of the sheet metal processing industry and the trend of automation, Vietnam is also facing many opportunities to adopt and apply this new technology.

C. Solutions and development orientation:

To overcome the challenges, businesses need to develop a detailed and effective investment plan. At the same time, they need to focus on training human resources to operate and maintain machinery. Another important factor is support from the government to facilitate the import of machinery and equipment.

V. CONCLUSION AND ADVICE FOR BUSINESSES WANTING TO APPLY AUTOMATIC BENDING AND FOLDING CENTERS.

A. Overall assessment of automatic bending and folding centers:
