This product is one of the proprietary products developed by Inno. The machine tool adopts a welded structure made of high-strength steel plates, designed using CAE/multiphysics engineering simulation software (Ansys). It is equipped with specialized high-load ball screws, guide rails, and imported bearings. Heat treatment technology is applied to eliminate residual stress, and sufficient reinforcing ribs are arranged to enhance the machine's load capacity, positioning accuracy, lifespan, rigidity, and reliability of precision.
This multi-sided panel bender is quick and easy to program, allowing for concurrent movement of multiple axes. It controls the suction cups to hold the sheet metal, manages the feeding or rotation of the material, and, using a versatile bending tool, enables multi-sided and multi-tool bending and forming of the workpiece. The bending efficiency, precision, and consistency are significantly improved. Compared to traditional press brakes, the overall efficiency of the multi-sided panel bender is 3 to 5 times higher, and energy consumption is reduced by 50%. It is the ideal equipment for the efficient and stable production of sheet metal parts such as box components and large panels. It is widely used in industries such as cabinets, air conditioning and refrigeration, elevators, kitchen equipment, aluminum panels, solar water heaters, automotive and bicycle parts, audio equipment, household appliances, and other equipment sectors.
Overall Layout and Structural Features of the Machine Tool
The LA-2500 polygonal panel bender is primarily composed of the bending mechanism and the feeding mechanism. The bending mechanism consists of six axes: front and rear bending axes X1/X2, upper and lower bending axes Y1/Y2, and upper and lower clamping axes Z1/Z2. The X-axis controls the forward and backward movement of the movable blade holder; the Y-axis controls the vertical movement of the movable blade holder; and the Z-axis controls the vertical movement of the upper pressing blade slide.
The feeding mechanism consists of five axes: front and rear positioning axis U1, left and right positioning axes D1/D2, workpiece rotation positioning axis C, and ejection lifting axis H1. The U-axis controls the forward and backward movement of the suction cup; the D1/D2 axes achieve the left and right positioning of the workpiece; the C-axis controls the workpiece rotation; and the H-axis controls the lifting of the workpiece.
In total, the machine is equipped with 11 axes by default. Through programmed control, the machine can perform combination bending processes such as forward/reverse angle bending, forward/reverse flattening, and forward/reverse large arc bending. An optional automatic tool changer can also be added, allowing for the automatic replacement of tools by adjusting the bending width through parameter settings.
Drive System
The X, Y, Z, and U axes of the machine tool use AC servo motors directly connected via couplings, providing strong rigidity and smooth, flexible movement. This drives the ball screw for stepless transmission, ensuring no crawling at low speeds and no vibration at high speeds, thus guaranteeing feeding accuracy of the screw. The Y and Z axis servo motors are equipped with an automatic braking function, which ensures that in the event of a power outage, the motor shafts are automatically clamped for safety protection.
C-Axis for Workpiece Rotation Positioning
The C-axis uses an AC servo motor paired with a high-precision reducer, ensuring positioning accuracy during rapid rotation with a repeat positioning accuracy of 5 arc seconds. The rotating spindle is integrated with the air circuit in a sealed design, ensuring airtightness of the air circuit during high-speed rotation at any angle. The rotating shaft is equipped with a vacuum suction cup assembly, which can be matched to different sizes based on needs.
D1/D2 Left and Right Positioning Axes
Both the D1/D2 left and right positioning axes use AC servo motors paired with high-precision reducers and high-precision timing belts. The left and right positioning blocks can move or lift, meeting the requirements for precise positioning and placement of the workpiece. After positioning is complete, the blocks automatically lower to avoid collisions during workpiece rotation.
Vision Detection Device
The system uses laser vision for online detection, capable of detecting angles and automatically compensating for them, resulting in higher product forming accuracy.
Bending Tools
This machine uses universal bending molds, allowing for the completion of various shapes of bends without needing to stop the machine to change molds. Polygonal bends can be formed in a single operation.
Machine Protection
The machine is equipped with a fully enclosed sheet metal casing. According to customer requirements, safety fences and safety light curtains can be added to prevent unauthorized personnel from entering the working area, eliminating potential safety hazards.
Electrical System
The main electrical components of this system are imported, and it adopts a closed electrical cabinet with a slot board wiring structure and air conditioning for heat dissipation. A mobile control panel is also provided. The system features self-diagnostic functions, enabling operators to understand the operating status of various parts of the machine through indicator lights and displays. The machine is equipped with an alarm system and an emergency stop button to prevent various unexpected malfunctions.
