1. Automatic Tool Changing
The system automatically switches upper blank holders according to imported drawings, reducing manual tool setup for flexible sheet metal bending.
2. 3D Bending Simulation
The control system supports 3D simulation, bending feature recognition, process planning, and collision checking before production.
3. Flexible Auxiliary Tools
Optional auxiliary bending tools support positive and negative folding for local bends and complex panel structures.
4. Durable 38CrMoAl Tooling
The upper blank holder uses 38CrMoAl material for better wear resistance and stable long-term bending performance.
5. High-Precision Tool Assembly
The 5mm thinnest tool blade supports 5mm tool assembly accuracy with ±0.5mm tool changing tolerance.
6. Wrapped Tool Mounting Structure
The wraparound tool structure and pneumatic locking device help improve tool stability during repeated bending.
7. Heavy-Duty Fuselage
The 80mm mainboard, annealed frame, four-step machining, and lean assembly support stable machine operation.
8. Metal Lubrication Lines
Metal lubrication lines, grinding lead screws, and roller guides help improve motion stability and reduce maintenance risk.
The fuselage's mainboard is 80mm thick. The fuselage and all structural components undergo annealing, four-step machining, and lean assembly. It is independently designed and manufactured according to the tool changing system's requirements, ensuring stability and high efficiency.
Automatic tool changer refers to the automatic switching of the upper blank holder. STON automatic tool changer panel bender automatically calculates the arrangement of the upper blank holder according to the drawings, which is convenient for flexibly switching the bending requirements of the workpiece.
The 3D simulation system automatically identifies bending features, unfolds the sheet material in reverse, and plans the bending process, displaying a complete animated simulation of the entire bending action on the screen. It confirms process feasibility and performs collision detection, eliminating the need for physical trial bending.
An optional auxiliary bending tool can be selected according to the workpiece requirements, supporting both positive and negative folding. This is to meet the needs of partial bending that is shorter than the length of the entire sheet of material.
The upper blank holder is made of 38Cromoal material, making it wear-resistant and durable. All circuits and air passages are protected by guide plates, preventing compression and friction during W-axis movement.
The tool changing accuracy is determined by the thickness of the thinnest tool in the tool assembly. The thinnest tool in the panel bender of the STON automatic tool changer is 5mm thick, the tool changing accuracy is 5mm, and the tool changing accuracy tolerance is ±0.5mm.
All tools are mounted in a wraparound design, and with the help of a pneumatic locking device, bending is more stable and precise.
All components, including metal lubrication lines, grinding lead screws, and roller guides for pressure block mounting, are of our company's high specifications.
