Introduction to the Function of the Bending Machine
The bending machine is a kind of forging machinery. Its main function is to perform sheet metal processing on sheets, especially large sheets. By matching various molds, sheets can be bent, stretched, Rounded, punched, etc., and widely used in light industry, aviation, shipbuilding, metallurgy, instrumentation, electrical appliances, stainless steel products, steel structure construction, and decoration industries.
The bending machine includes a bracket, a workbench, and a clamping plate. The workbench is placed on the bracket. The workbench is composed of a base and a pressure plate. The base is connected to the clamping plate through a hinge. The base is composed of a seat shell, a coil, and a cover. In the depression of the seat shell, the top of the depression is covered with a cover plate.
When in use, the wire is energized to the coil, and after energization, an attractive force is generated on the pressure plate, to realize the clamping of the thin plate between the pressure plate and the base. Due to the use of electromagnetic force clamping, the pressure plate can be made into a variety of workpiece requirements, and it can also process workpieces with side walls. The bending machine can meet the needs of various workpieces by replacing the bending machine mold.
The hydraulic bending machine adopts a steel plate welding structure; vibration aging eliminates stress, and the frame has good rigidity and stability; it works smoothly, is safe and reliable, and is easy to operate; it achieves the ideal bending effect through coordinated control of the electrical and hydraulic systems.
What Are the Types of Bending Machines?
The bending machine is divided into three types: manual bending machine, hydraulic bending machine, and CNC bending machine. Manual bending machine is divided into mechanical manual bending machine and electric manual bending machine. According to the synchronous mode, the hydraulic bending machine can be divided into mechanical synchronous bending machine, torsion axis synchronous bending machine, machine-hydraulic synchronous bending machine, and electro-hydraulic synchronous CNC bending machine.
According to the movement mode, the hydraulic bending machine can be divided into an up-moving type and a down-moving type. The down-moving type is when the workbench and the workpiece on the workbench move upward together, and the slider does not move. At present, it is relatively rare in the domestic market, and most of them are up-moving. The workpiece does not move, and the slider moves downward. According to the control mode, it can be divided into ordinary hydraulic sheet metal bending machine, economical CNC bending machine, and electro-hydraulic synchronous CNC bending machine.

They are ideal for situations where complex bends and high throughput are required, significantly improving production rates while maintaining exceptional quality standards.
Core Components of a Hydraulic Bender
Hydraulic Cylinder and Pump System
The hydraulic cylinder and pump system form the core of any Hydraulic Bending Machine. The pump produces the required pressure, which is then conveyed to the hydraulic cylinder. This cylinder applies the force essential for bending the material. The efficiency and dependability of the machine are significantly influenced by the design and quality of these components. Hydraulic cylinders need to be durable and able to endure high pressures, while the pump system must guarantee efficient and smooth operation.
Control Systems: Manual, Semi-Automatic, and Fully Automatic
Control systems vary across different types of hydraulic bending machines. Manual machines typically have basic control mechanisms, while semi-automatic and fully automatic machines feature more sophisticated controls. These systems can include programmable logic controllers (PLCs), human-machine interfaces (HMIs), and other digital interfaces that allow precise control over the bending process.

Supporting Structures: Frames and Dies
Supporting structures, including frames and dies, are critical to the machine’s function. The frame provides the necessary stability and support, ensuring that the machine can handle the pressure exerted during the bending process. Dies are used to shape the material as it is bent, and they must be designed to meet specific bend requirements. The quality and maintenance of these structures are vital to the machine’s longevity and performance.
The Operational Workflow of a Hydraulic Bending Machine
The operational workflow of a hydraulic bending machine starts with the preparation of the material, which is securely clamped into place. The operator or automated system then sets the desired bending parameters. Once the settings are confirmed, the hydraulic system is engaged, and the pump generates the necessary pressure to the cylinder. The cylinder pushes the material into the die, achieving the specified bend. Upon completion, the material is released, and the cycle repeats as needed. This process ensures accurate, repeatable bends with minimal human intervention.
How to Correctly Use CNC Hydraulic Bending Machine
CNC Hydraulic Bending Machine for Angle Bending
A CNC hydraulic bending machine for angle forming allows the user to specify the exact length of a bend without the need for a reference. The machine features two bending bolds that rotate during the bending process, giving a signal to the computer that determines the final stroke required. This system compensates for the spring back of each bend and provides high angle accuracy of +/ 0.2o, instantly after the first workpiece is inserted. The machine reduces the material waste compared to manual adjustment.
The CNC bending machine for angle forming comes with many features. One of these is its ability to bend aluminum in different orientations. The machine comes with up to fifteen independent servo axes, allowing the operator to control the bending process in a three-dimensional manner. Another feature is the ability to fine-tune roll positions to minimize unbent flat sections. By using the BIT angle roller, operators can reconfigure the machine to bend smaller workpieces without wasting material.
CNC Bending Machine for Imprint Bending
A CNC Bending Machine for imprint bending is the ideal machine for a wide range of applications. The machine has all the benefits of CNC technology, including a modern touchscreen colour display and two axes of control. Programming is easy and intuitive, with the user interface enabling 200 different programs to be stored and swapped at any time. Stroke settings can be changed in steps of +/-0.1deg. The machine is easy to operate using a foot switch or a special manual control cable. It can be run in automatic or jogging modes.
The software allows the operator to program bends by dragging and dropping bend steps. It is error-proof thanks to the scanning of the part ID code. The graphical tool mapping displays provide information on tooling locations and types, allowing the operator to load the correct part program. The upper ram is equipped with LED mapping for accurate tooling positions. A CNC Bending Machine for imprint bending can also be fitted with spiral bending devices for heat exchanger production.
Back Gauge Adjustment
During a CNC bending job, a back gauge must be adjusted on a CNC bending machine to accurately gauge the material bending. The bend line is set at the nose of the punch, and a half of the material elongation goes to either side of the center. The backgauge location can be determined after performing the calculations. The backgauge position must be set from the front face of the die, a distance one-half of the width of the die body.
The back gauge adjustment is used to position the sheet in the length direction during the bending process. The adjustment value is obtained by pushing a button on the front button box. The table shows the conversion value of the adjustment value, and the machine also has a hand wheel for fine adjustments. A typical CNC bending machine comes with a hand wheel and an electric quick-adjustment lever for the backgauge.
Stroke Adjustment
In order to adjust the stroke, a CNC bending machine should have an oil pump. Start the machine and press the button to activate the pump. After starting the machine, adjust the stroke and make sure the plates are lined up with the bottom mold. You must remember that the upper die must have sufficient clearance, or you will end up damaging the mold. The machine’s stroke adjustment features manual fine tuning as well as electric quick adjustment.
When adjusting the stroke on a CNC bending machine, you should know the open height and closed height of the bending machine. The open height is the height of the upper and lower beams when the upper beam is fully opened. The closed height is the height of the upper and lower beams when closed. You must remember that some of the materials in the machine will come in contact with the variable die when changing the opening. For safety reasons, you should not stand behind the CNC bending machine while working.
CNC Hydraulic Bending Machine for Bending Prisms with Electronic Angle Measurement
The CNC Bending machine for prisms with angular measurement features electronic angular measurement and two flattened bending bars. It has high accuracy of +/ 0.1o, and it is a popular choice for small batches and single pieces. The bending tool rotates while the material is being bent, allowing the operator to set the required final stroke. The system also has an impact system, which allows the user to define the angle of rotation from which the stroke is calculated.
The manufacturing process of glass prisms begins with a block of glass called a “blank” that is ground by a metal diamond bonded wheel. During this step, the majority of the glass is removed quickly, leaving flat but coarse surfaces. Once the prism-to-be is close to the desired dimensions, the machine will perform a fine grinding process to remove scratches and subsurface breaks. The smoothened glass surface should appear cloudy.
How Does Hydraulic System in CNC Machines
The hydraulic system in CNC machines, including CNC bending machines, plays a crucial role in providing the force necessary to carry out precision operations. Hydraulic systems are commonly used in CNC machines for their ability to generate high amounts of force while maintaining smooth, controlled movements. Here’s an overview of how the hydraulic system works in CNC machines:
1. Hydraulic Power Source
The hydraulic system is powered by a hydraulic pump, which is typically driven by an electric motor. The pump takes hydraulic fluid (usually oil) from a reservoir and pressurizes it, creating the force needed to operate the machine's various components.
2. Hydraulic Fluid
The hydraulic fluid (oil) is the medium that transmits the force within the system. The fluid travels through a network of hoses, valves, and cylinders to transfer power and enable precise movements of machine components. The choice of fluid is critical as it needs to have proper viscosity and lubricating properties to ensure smooth operation and to prevent wear on the system.
3. Hydraulic Cylinder
The hydraulic cylinder is one of the core components. It's responsible for converting hydraulic pressure into linear motion. Inside the cylinder, a piston moves back and forth depending on the direction of hydraulic fluid flow. The piston movement generates the force needed to perform tasks such as bending, pressing, or lifting on a CNC machine.
- In CNC bending machines, hydraulic cylinders control the motion of the ram that holds the tooling (die and punch). The force exerted by the hydraulic cylinder bends the material with great precision.
4. Control Valves
The hydraulic system is equipped with control valves that direct the flow of hydraulic fluid into the cylinders. These valves can be manually or electronically controlled, depending on the CNC machine. The valves regulate the pressure, speed, and direction of fluid flow, which in turn controls the movement of machine parts like the ram or the back gauge.
In CNC machines, the hydraulic valves are often operated through the machine’s programmable logic controller (PLC), allowing the machine to perform automated sequences with high precision.
5. Hydraulic Pressure and Force Control
The hydraulic pressure is adjustable, typically controlled by a pressure relief valve. This ensures the system operates within safe limits and prevents overloading. For CNC machines, the pressure can be precisely set to achieve the desired force for bending or pressing the material.
- For example, in a CNC hydraulic bending machine, the force applied by the ram needs to be adjusted based on the material thickness, bend angle, and tooling configuration.
6. Hydraulic Accumulators
Some CNC machines use hydraulic accumulators to store pressurized fluid. This helps to maintain steady pressure and smooth operation, even if there are fluctuations in the system's demand for power. Accumulators can provide additional pressure during moments of high demand, which is useful for tasks requiring rapid or heavy movements.
7. Maintenance of the Hydraulic System
Hydraulic systems in CNC machines require regular maintenance to ensure efficiency and longevity. This includes:
- Monitoring fluid levels: Ensuring there is enough hydraulic fluid for proper operation.
- Changing the fluid: Periodically replacing the hydraulic oil to prevent contamination.
- Inspecting hoses and seals: Checking for leaks, cracks, or wear.
- Cleaning the filters: Keeping the hydraulic filters clean to avoid contamination of the fluid.
How the Hydraulic System Works in a CNC Bending Machine:
- Ram Movement: In CNC hydraulic bending machines, the ram that holds the bending tool is moved by hydraulic cylinders. The pressure of the hydraulic fluid determines the force applied to the material being bent. The system allows for precise adjustments to the ram's speed and position.
- Back Gauge Adjustment: The back gauge, which positions the material accurately before bending, is often adjusted hydraulically to ensure the proper placement of the material for every bend. The hydraulic system provides the necessary force for quick and accurate back gauge movements.
- Bending Force: The machine’s hydraulic system is designed to apply a controlled bending force, depending on factors like material thickness, type, and desired bend angle. The CNC controller typically adjusts the pressure of the hydraulic system to match these requirements for optimal results.
- Automatic Stroke Control: The stroke of the hydraulic cylinder can also be adjusted, allowing for the fine-tuning of the bending process. This helps the machine achieve different types of bends, from shallow angles to more complex shapes.
Automated CNC Bending Machine
An Automated CNC bending machine is a modern manufacturing solution that can produce parts with high accuracy. It combines dedicated equipment with flexibility, such as mandrels, compression tooling, and a workbench. The machine is equipped with a hopper, a coil feed, and a bending modulus. The machine can also be equipped with robots and transfer units. These features enable the user to program parts easily and increase productivity.
The bending process began thousands of years ago with manually operated hammers and other hand tools. As metal sheets became abundant, this manufacturing process was quickly mechanised. The first bending machines, called “sheet metal bending brakes,” were large, heavy, and heavy. Eventually, the advent of hydraulics helped make work easier. Hydraulics powered the bending tool and a lever valve. At first, shears were powered solely by momentum. Similarly, the position of the bend was defined by a folding rule or a template.
The first generation of automatic benders came about when the steel rule became a common feature. These steel rules were hardened to maintain their shape even after undergoing several processes. Today, automatic benders are capable of several innovations, including side broaching and perforating rules.
CNC bending machines are used for the manufacturing of metal parts. These machines are equipped with three rolls – one fixed and two adjustable. The rotary part manipulator will move the workpiece to the desired position and bend the metal sheet into the desired shape. These CNC bending machines can also produce truncated cones and coils. This means that the price of CNC bending machines is highly competitive, as long as a qualified team is employed to perform the process.
Comparing Hydraulic Technology with Other Bending Technologies
Differences Between Hydraulic and Mechanical Bending Machines
Hydraulic and mechanical bending machines have distinct operational principles and use cases. Hydraulic Bending Machines utilize fluid power to apply consistent pressure, enabling them to handle various material types and thicknesses with high precision.
