What is a panel bending machine?

A panel bander is a machine used to bend sheet metal by applying pressure to the sheet through an upper and lower die to bend the metal into a specific geometric shape. The V-angle of the lower die is always adjusted according to the thickness of the sheet.

Types of Panel bending machine

Panel bending machines can be categorized into plate and tube bending machines. For the panel bending machines discussed in this article, we can categorize them into mechanical and hydraulic drive bending machines.

1. Mechanical bending machine: using a mechanical drive system to allow the machine to operate at high speeds and produce excellent bending accuracy. This is one of the more traditional types of bending machines. It is suitable for simple, repetitive bending tasks on very thin materials.
2. Hydraulic bending machine: The main feature of this machine is that it is equipped with a hydraulic cylinder that controls the pressure applied by the punch by varying the pressure of the cylinder. The hydraulic bending machine is more suitable for thick plates and has a higher bending accuracy. Compared to mechanical bending machines, it does not require much maintenance in the later stages of use.

Structure of a panel bending machine

Panel bending machine usually consists of the following parts:

1. Body: The body is the main body of the panel bending machine, usually made of steel or cast iron, with sufficient strength and rigidity to withstand the pressure and vibration of the process.
2. Upper and Lower Dies: The upper and lower dies are the core parts of a panel bending machine and are used to bend sheet metal into the desired shape. The upper and lower dies are usually high-strength alloy steel, resistant to abrasion and corrosion.
3. Pendulum arm: The pendulum arm is the part that connects the upper and lower molds and makes the upper and lower molds move relative to each other during the process through the pendulum movement.
4. Operating system: the operating system is usually composed of a CNC system and hydraulic system, which is used to control the operation of the panel bending machine and various parameters during the processing, such as bending angle, bending radius, bending speed, etc.
5. Support device: support the metal sheet to be processed to ensure the stability and accuracy of the sheet during processing.
6. Clamping device: tight metal plate to be processed to ensure that the processing process does not occur during the plate movement or sliding.

In short, the structure of the panel bending machine is complex, but through the synergistic effect of the various components, it can realize efficient and accurate metal sheet processing.

Features of Panel bending machine

Common Bending Methods

Free Bending:

Free bending, also known as air bending, is simpler than other methods. The depth of the upper mold controls the bending angle into the V-groove of the lower mold.
The accuracy of a bent part depends on various factors, such as Y1, Y2, V-axis upper and lower molds, and plate.
However, it is widely used due to its versatility and wide processing range. It is suitable for simple, large or less productive structures.

Three-point bending:

Three-point bending, also known as mold bending (bottoming), has a bending angle determined by the height of the wedge in the lower mold.
The upper die provides only sufficient bending force and eliminates non-parallelism between the dies using hydraulic pads on the ram.
This method allows the production of high-precision parts, i.e., with low angular and straightness errors. It is used for complex structures, small sizes and batch processing.

Corrective bending:

Corrective bending is formed in the cavity formed by the upper and lower molds, which can obtain the desired cross-section shape. However, it requires a larger bending force and repeated mold repair, and the generality of the mold could be better. When special requirements or cross-section shapes can not be realized by free bending, often use this bending method.
