The fully automatic production line for laser cutting and bending includes coil rack, leveling device, laser machine, material receiving platform, panel bender（or turret punch press）,centering platform and truss（or robot arm）.Customized,the parameters of the production line are determined according to the customer's steel coil size, weight, plate material and thickness as well as product drawings.
Cutting efficiency is higher by reducing the time for plate loading, and waste pick-up efficiency increases by 50%. Plate utilization is improved by cutting only the required amount, avoiding the disadvantage of sizing and compensating each sheet. Manual labor intensity is reduced—no pre-sizing cuts and no manual plate lifting—greatly improving work efficiency. A single control system enables automatic sorting and processing with manual/automatic integration, and the operation is simple and user-friendly compared with ordinary machines that require importing graphics every time.

Automatic Laser Bending Production Line delivers high-precision, high-quality cuts for a wide range of sheet-metal applications. See how it’s used across industries to create parts with perfect consistency and accuracy:
The fully automatic production line for laser cutting and bending includes coil rack, leveling device, laser machine, material receiving platform, panel bender（or turret punch press）,centering platform and truss（or robot arm）.Customized,the parameters of the production line are determined according to the customer’s steel coil size, weight, plate material and thickness as well as product drawings.
The coil rack feeds steel coils into the production line, supporting continuous uncoiling for automated operation. As a critical step in a coil fed laser cutting system, this stage ensures seamless material preparation for downstream modules.
The leveling equipment straightens uneven sheet metal coils using multiple sets of precision rollers. It eliminates surface waves and twists to ensure high flatness—crucial for high-precision laser cutting automation and reliable downstream forming.
The leveled sheet enters the laser cutting unit, where advanced laser cutting technology delivers precise cuts per pre-programmed designs. Whether cutting complex geometries or intricate part contours, the sheet metal production line ensures clean edges and millimeter-level accuracy using high-energy-density lasers.
The robotic system works in tandem with the laser cutting unit. Its flexible robotic arm provides precise gripping and positioning for fast, stable loading and unloading. This automation significantly enhances the productivity of the coil-to-cut production process.
After cutting, sheet metal parts are transferred to the panel bender by a robot. This station bends sheets into required angles or curves with high precision. Whether for straight angles or complex folds, it ensures accurate automated sheet metal bending as part of the complete production line.
For high-mix and complex bending needs, the flexible bending center integrates CNC control and smart algorithms. It allows rapid switching of bending dies and process settings, enabling efficient sheet metal forming across a wide range of sizes and geometries—seamlessly connected via robotic handling systems.
The bent sheet metal parts are transferred by the robot to the manipulator welding forming station. The manipulator welding forming equipment is equipped with a high-precision welding system and a visual tracking system, which can automatically select the appropriate welding process (such as argon arc welding, spot welding, etc.) and welding parameters according to the welding requirements of the sheet metal parts. During the welding process, the visual tracking system monitors the weld position in real time and guides the manipulator to accurately complete the welding operation, ensuring that the weld is uniform and firm, and the welding quality is stable and reliable.
There are two forms of automated loading and unloading: truss and robotic arm
（1）The robotic arm grabs the sheet metal parts that have been processed by leveling, laser cutting and other preliminary processes from the processing area with its flexible joints and precise positioning capabilities. The grabbing device at the end of the robotic arm can be adaptively adjusted according to the shape and size of the sheet metal parts to ensure a smooth and reliable grabbing process and avoid damage to the workpiece. After grabbing, the robotic arm quickly transfers the sheet metal parts to the starting position of the truss conveyor track.
（2）The truss automation system offers a cost-effective solution for stable, high-load transfer of sheet metal components. Powered by servo drives, it ensures fast and precise positioning along predefined tracks—enhancing the speed and reliability of the overall sheet metal production line.
