How do electric press brakes compare to hydraulic press brakes?

Electric bending machine and hydraulic bending machine are two common bending machinery and equipment in modern metal workpiece processing. They have certain differences in the use of technology, performance advantages and scope of application. So, what is the difference between these two types of bending machines? Which bending machine is more suitable for your needs? In this article, we will compare the electric bending machine and hydraulic bending machine from the following aspects and hope to be able to provide you with some reference.

principles of electric bending machine and hydraulic bending machine

First of all, the electric bending machine is a kind of bending machine driven by servo motors, through the frequency converter to control the speed and torque of the motor, to realize the accurate control of bending force, bending speed, bending angle and other parameters. It works by driving the beam, upper and lower molds so that the workpiece is bent between the upper and lower molds.
The main features of an electric bending machine are simple structure, easy to use, and flexible operation. It is suitable for simple bending processing, especially for small workpiece bending processing. The advantages of electric bending machines are relatively low price, low maintenance cost and simple operation. However, its bending accuracy and work stability are relatively low, and the scope of application is limited.

hydraulic press brake bending machine

Unlike an electric bending machine, a hydraulic bending machine is a kind of bending mechanical equipment controlled by the hydraulic system. The principle of hydraulic bending machine is to press the oil into the cylinder of hydraulic pump and use the change of oil pressure to make the workpiece bend. Hydraulic bending machine is characterized by stable work and high precision, suitable for large workpiece bending processing.
It is suitable for workpiece processing that requires high bending accuracy and work stability. The advantages of hydraulic bending machine is high bending accuracy, and the ability to withstand a large workpiece load, applicable to a wide range. However, the price of hydraulic bending machines is higher, the maintenance cost is relatively high, and the operation is relatively complex.

different technical characteristics

Electric bending machines and hydraulic bending machines have many different technical characteristics, take the following two examples:

hydraulic press brake bending machine

– Bending range: electric bending machine bending range is generally between 1-6 meters, suitable for the bending of different lengths of plate processing. Hydraulic bending machine bending range is generally between 1-12 meters, suitable for bending processing of longer plates.
– Bending mode: electric bending machine bending mode generally has two: synchronous mode and asynchronous mode. Synchronous mode refers to the upper and lower mold movement at the same time, to ensure the consistency of the bending angle. Asynchronous mode refers to the upper and lower mold movement, which can be realized in different positions of the bending angle adjustment. Hydraulic bending machine bending mode is generally only one: synchronous mode.

How to choose bending macine

When choosing the right bending machine, it is necessary to make comprehensive considerations based on specific needs.
If the workpiece is small, the accuracy requirements are not high, and the budget is limited, you can choose the electric bending machine; if the workpiece is large, the accuracy requirements are high, and the budget is sufficient, you should choose the hydraulic bending machine.
It should be noted that, in addition to considering the performance of the machine itself, but also needs to consider the supplier’s quality of service, after-sales service and reliability of the equipment, to ensure that the purchase of the bending machine suits their needs.

Conclusion

Electric bending machine and hydraulic bending machine are both a kind of excellent bending machine, as long as you choose the right bending machine according to your needs and conditions, you can realize the high quality bending processing of the plate.
