IntroductionA 30-ton sheet bending machine is a powerful industrial device used for bending metal sheets into desired shapes with high precision. It operates using hydraulic or mechanical force to apply pressure on a sheet metal workpiece, shaping it according to a pre-set die or tooling arrangement.
Main ComponentsFrame Structure
Made of heavy-duty steel for rigidity and stability.Designed to withstand high bending forces without deformation.Hydraulic or Mechanical System
Hydraulic System: Includes a hydraulic cylinder, pump, motor, and valves to generate force.Mechanical System: Uses gears, levers, or screw mechanisms for force application.Bending Die & Punch
Die: A fixed lower part that shapes the metal sheet.Punch: The moving upper part that presses the sheet into the die for bending.Different dies (V-die, U-die, etc.) allow various bending angles.Ram (Pressing Beam)
Moves vertically to apply pressure on the sheet metal.Operated by a hydraulic piston or mechanical crank system.Back Gauge System
Used for positioning the metal sheet accurately before bending.Can be manually adjusted or CNC-controlled for precision.Control Panel
Includes buttons, levers, or a touchscreen interface.Controls the pressure, bending angle, and operation mode (manual, semi-auto, or automatic).Foot Pedal or Hand Lever
Used for operator control of the bending process.Safety Mechanisms
Emergency stop button to halt operations immediately.Safety guards to prevent accidental hand injuries.Light curtains & sensors for automatic stop if an obstruction is detected.
- Working PrincipleThe metal sheet is placed between the die and punch.The back gauge is adjusted for the desired bend position.The ram moves downward under hydraulic or mechanical force.The punch presses the sheet into the die, forming the desired bend.The ram retracts, and the bent sheet is removed.
