Hydraulic Sheet Metal Bending Machine (63 Ton x 2500 mm)

Hydraulic Sheet Metal Bending Machine 

Below are the typical specifications and factors to consider:

1. Tonnage

• Range: Typically 40 to 1000+ tons.
• Function: Determines the maximum force the press brake can exert on the material. The tonnage needed depends on the material thickness, length, and type.

2. Bending Length

• Range: Usually between 4 and 20 feet (1.2 - 6 meters).
• Function: Refers to the maximum length of material that can be bent at once. Longer lengths are used for larger sheets and parts.

3. Stroke Length

• Range: Often between 6 to 15 inches (150 - 380 mm).
• Function: Determines the distance the ram can travel during bending, affecting how deep the material can be pressed.

4. Throat Depth

• Range: Typically from 6 to 16 inches (150 - 400 mm).
• Function: Refers to the distance from the frame to the center of the ram. A larger throat depth allows for more complex shapes to be bent.

5. Open Height (Daylight)

• Range: Often between 10 and 20 inches (250 - 500 mm).
• Function: The maximum opening between the bed and ram when fully retracted, allowing for larger or taller dies to be used.

6. Approach, Bending, and Return Speeds

• Speeds: Expressed in inches per second (or mm/s).
• Function: Defines how quickly the press brake moves toward the material, how fast it bends, and how quickly it returns.

7. Backgauge

• Features: Manual or CNC-controlled.
• Function: Positions the workpiece precisely for repeated bends. Multi-axis backgauges allow complex part bending.

8. Control System

• Options: Manual, NC (numerically controlled), or CNC (computer numerical control).
• Function: Defines how the machine's operation is controlled, with CNC systems allowing for more precise, automated, and complex bending sequences.

9. Power Requirements

• Range: Varies widely based on tonnage and size (typically 3-phase, 220V/440V).
• Function: Determines the electrical power needed to run the machine.

10. Frame and Bed Type

• Types: C-frame or closed frame; welded steel or cast iron.
• Function: Determines the structural rigidity of the machine, affecting accuracy and durability.

11. Material Thickness Capacity

• Range: Dependent on tonnage (typically from thin sheet metal up to 1 inch or more for higher-tonnage models).
• Function: Dictates the maximum thickness of material that can be bent.

12. Optional Features

• Examples: Hydraulic clamping, crowning system, angle measurement systems, quick-release tooling, etc.
• Function: Enhances productivity, accuracy, and flexibility in operation.
