In today’s highly competitive manufacturing landscape, utilizing the right technology is crucial for success. Compared with other bending machine, panel benders have more complete functions, higher automation levels, and safer operation environment in the metal manufacturing industry. When choosing a press brake and a panel bender machine, manufacturers should consider the specific needs of their production process. In metal manufacturing, accuracy and efficiency are crucial, and panel benders perform excellently in both aspects. The use of panel benders can also reduce labor and material costs through efficient mass production. The production cost of a panel bender is much lower than that of a press brake in some working condition, but the operation of a panel bender is simple. The CNC (Computer Numerical Control) panel bending center represents the pinnacle of panel bender technology. This article explores the origin and development of panel bending machines, from basic operations to advanced automation, and how they fundamentally change metal manufacturing. Whether you are a small operator or a large industrial enterprise purchaser, understanding the functions of these machines can significantly improve your production efficiency and product quality.

The working principle of the panel bending machine is different from that of the hydraulic press brake. When operating a panel bender, the operator only needs to load the metal plate. The positioning, bending, and reversal of workpieces are controlled by machines and software.

The panel bending machine will not press the metal plate into the lower mold through a punch. The panel bender is a pair of blades that fix the sheet metal and bend it up and down to form the final contour. When bending a complex angle, the blade oscillates around a bending point until the desired angle is reached.

Panel bender molds will not move up and down in a straight line, which is different from a press brake tooling. After positioning the sheet, the panel bending machine can quickly adjust to the correct tool length. When bending, after positioning the workpiece, the clamping beam tool clamps the workpiece in place. Move the lower tool upwards to bend in the positive direction and move the top tool downwards to bend in the negative direction.

Initially, the preparation phase begins with selecting the metal plate to be bent. The operator inputs necessary parameters into the control system, including metal type, thickness, size, and required bending angle. This setup stage is crucial to ensure that the machine’s settings meet the specific requirements of the work at hand.

After setting up, place the metal plate on the workbench of the machine. The rear gauge is adjusted according to the programming settings to accurately align the sheet for the first bending. This positioning is crucial for the accuracy of bending position and angle.

Once the sheet is in place, the clamping system will activate to secure the metal sheet, preventing any movement during the bending process. This stability is crucial for achieving precise bending and maintaining material dimensional integrity.

The bending process begins when the panel bender blade applies force to the metal plate to produce bending at a specified angle. The control system carefully adjusts the force and angle to ensure precise execution of each bend. Based on the complexity of the parts, the machine may perform multiple bends in sequence, and if necessary, reposition the sheet with the help of a rear gauge.

Throughout the entire operation process, the control system continuously monitors the process and makes real-time adjustments to compensate for any changes in material properties or external factors. This adaptive ability ensures that the final product meets the specified dimensions and tolerances, demonstrating the accuracy and flexibility of the machine.

In summary, the panel bending machine operates through careful preparation, positioning, fixation, bending, and continuous monitoring processes. This process highlights the role of machines in modern manufacturing, where accuracy, efficiency, and adaptability are crucial. By understanding the working principles of these machines, operators can optimize their use, thereby improving the productivity and quality of metal forming operations.

A panel bending machine is a machine that functions similar to a press brake, but is more automated and has more functions. In the past, manual panel benders were used for metal bending.

Let’s explore different types of panel bending machines, their advantages and disadvantages, and determine the most suitable project for them.

The blade of the panel bending machine can form a flange in the horizontal direction, while the blank holder in the other direction can maintain the stability of the material. Standard curved blades can produce many types of radii. The bending of the panel bending machine will not leave any marks.

Compared to the bending workpiece of the CNC press brake machine, it will be more beautiful and cleaner. Compared with previous bending machines, this automatic panel bender has the advantages of being labor-saving and high-speed.

Panel bender is a widely used tool that can perform fully automatic bending processes, including automatic loading and unloading of tools, feeding, measurement, bending, and output. It has a short bending stroke and fast feed rate, which can produce highly accurate workpieces.

Special tools can be used for complex bending, such as crimping and offset bending. However, not all workpieces are suitable for panel bending machines. Generally speaking, it is more suitable for producing box shaped workpieces because it can bend the entire side of the box in one go.

Nowadays, press brake can also connect to robots to achieve complete automation, but their functions are not as complete as those of robot panel bending centers in some bending conditions.

A panel bender is a specialized machine used for bending metal sheets. It has an automatic tool changer, which reduces installation time. A complete set of tools can complete the complex bending of all workpieces. The tool of the panel bending machine has a very small interaction area on the surface of the metal plate.

The surface of the workpiece produced in this way has almost no scratches. The tool wear of the automatic panel bender machine is also minimal because there is little friction between the tool and the metal surface. The entire process of the sheet metal bending can be automated, saving human resources.

The bending angle variation of a panel bender is formed by the movement of the upper and lower blades, so its tools are not as complex as those of a bending machine. The fully automatic panel bending machine is equipped with an automatic tool changer, which can quickly change tools and adjust bending operations at various angles in various bending tasks.

Some large workpieces with positive and negative flanges are suitable for manufacturing using panel bending machines. If the panel bender can automatically set the billet gripper, only one operator can operate it. The panel bending machine only applies pressure to the metal plate through the upper and lower blades.

This bending method makes the changes and rebound of the metal plate less obvious, and can bend the entire box side in one go. The bending method of the panel bender is very suitable for producing boxes, lids, and similar items.

There are some safety issues when using modern pressure brakes to manufacture small parts. The panel bender can produce smaller profiles through clamping claws or manual operation.
