A press brake bending machine is an industrial equipment used for sheet metal processing, mainly used to bend sheet metal into the desired shape and angle. The bending machine bends the sheet metal by applying mechanical force and is widely used in various fields in the manufacturing industry.
Through the relative movement of the upper die and the lower die, the bending press machine applies pressure to the sheet metal placed therein, causing it to plastically deform along the shape of the die, and finally achieve the predetermined bending angle and shape.
The press bending process of sheet metal is a process in which a sheet metal is bent along a straight line into a specific angle or shape by applying external force. Bending is widely used in the forming of various metal components in the manufacturing industry, such as automotive parts, building structures, aerospace components, etc.
- Automobile manufacturing: production of automobile bodies, chassis, brackets and other parts.
- Aerospace: manufacturing high-precision parts such as aircraft fuselages, wings, brackets, etc.
- Construction engineering: production of building steel structures, steel plates, etc.
- Home appliance manufacturing: production of home appliance housings, internal brackets, etc.
- Shipbuilding: processing hull structural parts and support parts.
The principle of bending is based on the plastic deformation characteristics of metal materials. Under the action of external force, metal sheets can be permanently deformed within a certain stress range without breaking. Bending uses this characteristic to bend metal sheets into the desired shape through mechanical force. The following is a detailed working principle:
The press brake bending machine applies pressure perpendicular to the plate surface to the metal sheet through the upper and lower dies. The upper die (punch) moves downward and presses the metal sheet into the lower die (die).
The applied vertical pressure generates a bending moment near the bending line of the sheet, causing the metal sheet to plastically deform along the bending line.
Under the action of the bending moment, the inner layer of the metal sheet is subjected to compressive stress, while the outer layer is subjected to tensile stress. The different stresses of the inner and outer layers cause the metal sheet to bend at the bending line.
As the upper die continues to move downward, the metal sheet gradually bends into an angle and shape consistent with the shape of the die. The bending angle and radius are determined by the shape and relative position of the upper and lower dies.

The Ultimate Guide: Metal Sheet Bending Process
The plasticity, hardness and thickness of different metal materials affect the difficulty of bending processing and the quality of finished products. For example, materials with greater hardness require greater force for bending.
The thicker the sheet, the greater the bending force required, the larger the bending radius, and the higher the bending difficulty.
The shape of the upper and lower dies determines the bending angle and bending radius. Different mold combinations can achieve different bending effects.
The force applied by the press brake bending machine must be large enough to ensure that the sheet undergoes plastic deformation rather than elastic deformation or fracture during the bending process.
The appropriate bending speed can improve processing efficiency and quality, and avoid material cracks or uneven deformation caused by too fast or too slow.
The most common bending method, suitable for a variety of thicknesses and materials. It is achieved by a V-shaped lower die and a corresponding upper die.
Used to form a workpiece with a U-shaped cross-section, usually requires multiple processes to complete.
By rotating the upper die, pressure is applied to the sheet to bend it into shape. It is suitable for high-precision and complex-shaped bending.
The upper die does not fully enter the lower die, and the bending is completed by the elastic reset of the sheet itself. It is suitable for bending of large angles and special shapes.
Bending is one of the key forming processes in the manufacturing industry. By reasonably selecting equipment, molds and process parameters, the bending of various complex metal sheets can be completed efficiently and accurately. Let's take a look at the bending machine.
