An Overview of Electric Press Brake Machines and Purchasing Tips

As the name implies, a press brake is a mechanical device that bends and forms metal sheets (especially sheet metal). It uses advanced CNC systems to accurately calculate and press flat metal into various preset shapes, and eventually becomes various parts of the modern sheet metal manufacturing industry, including metal parts, components, shells, crafts, etc.
With the advancement of science and technology, the research and development technology of press brakes has also grown with each passing day, and electric press brake machines that are green, environmentally friendly, energy-saving and efficient have also emerged. Next, I will introduce the definition, working principle, advantages, and purchase methods of electric press brakes one by one, and discuss its future trends in the development of the industry.

What is an electric press brake

Unlike traditional hydraulic/mechanical press brakes that rely on oil pumps or mechanical energy, electric press brakes are a type of equipment that uses electric motors and screws to bend sheet metal. It has a compact structure, 100% pure electric operation, 0 fuel consumption, more energy-saving and environmentally friendly, and simpler maintenance. It is known as a “bending artifact” in high-repeatability, fine sheet metal processing production lines.

Basic principles and structure of electric press brake

1. Basic working principle

Basic working principle
The servo motor drives the servo system through the screw rod, directly drives the upper beam (slider) to move up and down quickly, and uses the shape of the mold to achieve accurate bending of metal sheets. Because the return stroke is directly driven by the spring or motor, its response speed and accuracy are guaranteed, which is suitable for large-scale and rapid production of lightweight workpieces.

2. Composition of the electrical drive system

The main components include screw, back gauge, servo motor, Fast Clamp、Front Plate Support、4V Concentric Die、Crowning、Grating Ruler、Foot Switch and Enclosed Cabinet, etc.

Main features of electric press brake

1. Energy efficiency improvement

Pure servo electric press brake works on demand, and saves at least 30% energy in electricity consumption compared with hydraulic type;

2. High precision and repeatability

Strong controllability, the precision can usually reach 1 micron repeating action;

3. Green and environmentally friendly

Pure servo motor drive, 0 noise, 0 oil pollution, quiet and environmentally friendly;

4. Safe and friendly

Equipped with multiple safety protection devices, and the operation interface is simple and friendly, the operator works safely and is easy to use.

Advantages of electric press brake

1. Energy saving and cost-effectiveness

Long-term electric drive reduces the operating cost caused by production oil consumption;

2. Low maintenance requirements

No complex hydraulic system, basically 0 maintenance can be achieved;

3. High production efficiency

Super motor response speed, fast switching and adjustment, small batch and multi-variety production efficiency is significantly improved.

Classic application field

Electric servo press brake is more used in light sheet metal processing industries such as household appliances, metal crafts, hardware parts, kitchen equipment, etc.

The difference between electric press brake and hydraulic CNC press brake

I have introduced the detailed hydraulic CNC press brake in the previous article. If you are interested, you can check it out: Definition, working principle and selection guide of hybrid press brake, Here I will only analyze the two in terms of applicable occasions:

Electric press brake machine has a compact appearance, energy-saving and precision, suitable for high-precision processing of small and medium-sized parts and areas that call for energy conservation and emission reduction;
Hydraulic CNC press brake can be designed according to customer needs. It is suitable for large-tonnage, heavy-load and large-volume bending occasions;

Precautions for purchasing electric press brake

If you have planned to buy an electric press brake, then we need to pay attention to the following matters when purchasing:

Conclusion

With the globalization of climate warming and increasingly serious environmental pollution, local governments have successively introduced energy-saving and emission reduction policies. Electric press brakes are becoming an important discovery direction and future mainstream equipment in the sheet metal industry. They are high-precision, high-speed, and high-configuration. At the same time, they are green, environmentally friendly, energy-saving and low-consumption, subverting tradition! If you are in the sheet metal processing industry, I look forward to it working with you for a better future! The above is my overview of electric press brakes today, I hope it will be helpful to you!
