"A Hydraulic Press Brake Operates In Multiple Stages To Bend And Shape Metal Sheets With Precision. The Stages Of Operation Typically Include"
1. Clamping Stage
The Metal Sheet Is Placed On The Press Brake Bed.
The Back Gauge Is Adjusted To Ensure Correct Positioning.
The Upper Punch (Ram) And Lower Die Are Aligned.
Hydraulic Clamps Secure The Sheet In Place.
2. Preparation
Material Selection: Choose The Appropriate Metal Sheet Based On Thickness, Type, And Required Bend.
Tooling Setup: Select And Install The Correct Punch And Die Based On The Desired Bend Angle And Material Properties.
Machine Calibration: Ensure The Press Brake Is Calibrated For Accurate Bending, Including Back Gauge Positioning And Ram Alignment.
3. Programming
Input Parameters: Enter The Required Dimensions, Bend Angles, And Sequence Into The CNC Controller.
Simulation: Run A Simulation To Verify The Program And Avoid Collisions Or Errors.
4. Positioning
Sheet Placement: Position The Metal Sheet On The Press Brake Table, Aligning It With The Back Gauge For Accuracy.
Clamping: Secure The Sheet In Place To Prevent Movement During Bending.
5. Bending Stage
The Hydraulic System Activates, And The Ram (Punch) Moves Downward.
The Punch Presses The Sheet Into The Die, Applying Force To Create The Bend.
The Hydraulic System Regulates The Force And Speed To Achieve The Desired Angle.
6. Holding Stage
The Press Holds The Material Under Pressure To Ensure Proper Bending.
The Dwell Time (Holding Duration) Depends On Material Thickness And Bending Requirements.
7. Return Stage
The Hydraulic System Releases Pressure.
The Ram Retracts To Its Original Position.
The Metal Sheet Is Released And Repositioned If Further Bends Are Required.
8. Unloading Stage
The Operator Removes The Bent Metal Piece.
The Piece Is Inspected For Accuracy.
The Process Is Repeated For Additional Bends Or New Workpieces.
9. Inspection
Measurement: Use Tools Like Protractors Or Angle Gauges To Verify The Bend Angle And Dimensions.
Adjustment: Make Any Necessary Adjustments To The Machine Or Tooling If The Bend Does Not Meet Specifications.
10. Completion
Unloading: Remove The Bent Part From The Press Brake.
Post-processing: Perform Any Additional Operations, Such As Deburring Or Finishing, If Required.
11. Maintenance
Tooling Check: Inspect The Punch And Die For Wear And Replace If Necessary.
Machine Maintenance: Regularly Check Hydraulic Fluid Levels, Seals, And Other Components To Ensure Optimal Performance.
