Torsion bar synchronize CNC press brake
Torsion bar synchronize CNC press brake
The base frame comprises a housing, a coil, and a cover plate. The coil is located within a recess in the housing, the top of which is sealed by the cover plate. During operation, the coil is energized by a wire. When energized, the coil generates an electromagnetic attraction force on the pressure plate, thus firmly clamping the thin sheet between the pressure plate and the base frame.
Because clamping is achieved through electromagnetic force, the pressure plate can be easily adjusted to accommodate various workpiece shapes. This design also makes it possible to process workpieces with sidewalls. By simply changing the bending dies, the machine can be configured to meet the processing needs of various different workpieces.

1.Introduction for Torsion bar synchronize CNC press brake:
A bending machine is a device designed for bending thin metal sheets. Its structure primarily consists of a base, a worktable, and a clamping plate. The worktable is mounted on the base and comprises a base frame and a pressing plate, which are connected to each other through a hinge.
The base frame is made up of a housing, a coil, and a cover plate. The coil is seated within a recess in the housing, and the recess is closed at the top by the cover plate. During operation, the coil is energized through electrical wiring. Once energized, it generates an electromagnetic attractive force on the pressing plate, securely clamping the thin sheet between the pressing plate and the base frame.
Because clamping is achieved through electromagnetic force, the pressing plate can be easily adapted to accommodate various workpiece shapes. This design also enables the processing of workpieces with side walls. Additionally, by simply changing the bending die, the machine can be configured to meet the requirements of a wide range of different workpieces. The entire operation is straightforward and user-friendly.

3.Characters for Torsion bar synchronize CNC press brake:
3.1 Structural Design
The machine frame is constructed from full steel welding, ensuring high strength and rigidity to withstand heavy-duty bending operations.
3.2 Hydraulic Drive System
Hydraulic transmission is employed, with oil cylinders positioned at both ends of the machine directly mounted on the slider. This configuration provides direct and efficient sliding operation.
3.3 Slider Synchronization
The slider synchronization mechanism utilizes a torsion shaft forced synchronization system, ensuring precise and balanced movement of the slider during operation.
3.4 Mechanical Stop Mechanism
A mechanical stop block structure is adopted, offering stable and reliable positioning for consistent bending results.
3.5 Stroke Adjustment
The slider stroke can be flexibly adjusted through either automatic or manual control, with the current position clearly displayed on the counter for easy monitoring.
3.6 Deflection Compensation
A wedge-type deflection compensation mechanism is incorporated to effectively counterbalance frame deflection, thereby ensuring high bending accuracy throughout the entire process.

A hydraulic press brake uses hydraulic cylinders to generate bending force, offering high tonnage capacity and smooth, powerful operation—ideal for thick and heavy plates. A servo-electric press brake uses servo motors and ball screws for motion, providing higher speed, lower energy consumption (up to 50% savings), and cleaner operation (no hydraulic oil). Servo-electric models are best suited for light-gauge sheet metal and high-speed production, while hydraulic models remain the standard for heavy-duty fabrication.
The machine supports three primary bending methods:
Air bending – the punch does not fully press the material into the die; angle is controlled by stroke depth. Most common, flexible, and requires less tonnage.
Bottoming – the punch forces the material fully into the die for high accuracy and minimal springback.
Coining – extreme pressure deforms the material permanently; highest accuracy, used for precision parts.
Typical press brakes offer bending lengths from 1,500mm to 16,000mm, with pressing forces from 400 kN to 20,000 kN (40 to 2,000 tons). Maximum bending thickness depends on material type, tooling, and machine capacity—for mild steel, this can range from 1mm up to 25mm or more. Customized models are available for thicker or longer plates.
Crowning is a compensation mechanism that counteracts deflection of the frame and table during bending. As the ram applies force, the frame tends to flex slightly in the center, causing a bend angle that is shallower in the middle than at the ends. Auto-crowning systems (mechanical or hydraulic) raise the table or adjust the ram in the center to compensate, ensuring a uniform bend angle along the entire workpiece length. This is critical for long parts where consistent accuracy is required.
