Product Advantages
Exceptional Precision
High-precision ball screw back gauge system features an X-axis positioning accuracy of ±0.05 mm and a repeatability of ±0.02 mm, ensuring dimensional consistency across entire bending batches.
Enhanced Production Efficiency
Automated processes, combined with minimal time required for mold changes and back gauge adjustments-along with rapid approach speeds-boost single-shift production capacity by over 30%.
Robust and Durable Construction
The machine frame is welded from high-strength Q345B steel plates and undergoes integral tempering for stress relief; the guide rails and slider utilize heavy-duty roller guides, designed for a service life of ≥10 years.
Ease of Operation
A 7-inch touchscreen with icon-based parameter settings supports the storage of 99 programs, allowing new operators to independently perform mold changes and bending operations after just 2 hours of training.
Comprehensive Safety
Standard features include light curtains, dual-hand synchronous start buttons, emergency stop switches, and hydraulic overload protection, fully complying with CE safety standards.
Bending Process
Rapid Descent
The upper slider comes down fast. It is pulled down by gravity or extra hydraulic cylinders. As it gets close to the workpiece it switches to a slow coming down mode.
Slow Descent
The hydraulic system gives pressure. This pressure pushes the part into the workpiece. The workpiece then sits in the V-groove of the part. This action bends the material. How much it bends is decided by how deep it goes.
Pressure Holding
When the bending angle is right the system keeps the pressure on for a time half a second, to a second. This helps stop the material from springing
Return Stroke
The hydraulic valve changes direction. The upper ram then rises fast. This completes one cycle of bending.
Key Points for Routine Maintenance
Hydraulic System: You need to replace the oil with new ISO VG 46 anti-wear hydraulic oil every year. At the time you should clean the filter element. Also check the hose connections every month to make sure there are no leaks.
Guide Rails and Lead Screws: The guide rails and lead screws need some care too. You have to apply lithium-based grease on them every week. Then every two weeks you should clean the backgauge guide rails so that metal chips do not cause any problems.
Dies: After you change the dies you must clean the lower dies. Look for any indentations or cracks on the surfaces. If the wear on the V-groove of the die is than 0.3 mm you have to replace the die.
Light Curtain: During every shift take a cloth and wipe the light curtain windows. This will keep them free of oil stains or anything that might block them.
Precision Calibration: Every six months you have to calibrate the bending angle. You can use an angle tester or a standard test block to do this. If the bending angle is not correct by more, than ±1° you will have to adjust the compensation parameters.
