CNC Sheet metal folder

Large metal plates can be operated by one person

No indentation on bent products

Handles varying plate thicknesses without mold changes

Ensures consistent internal void sizes for box-shaped workpieces

Supports negative angle bending and leveling with the same mold

sheet metal folding machine

Fully electric CNC Folding Machine, featuring three servo motors that independently control positioning, clamping, and bending actions. Once positioning is complete, the clamping die secures the material, and the bending axis begins the bending process.

Introduction to the control axis of CNC sheet metal folder

  • 1 Axis (Left) / 2 Axis (Right): Primary positioning axes.
  • Z1/Z2 Axes: Clamping beam control axes, responsible for securing the material.
  • Y1/Y2 Axes: Bending beam control axes, responsible for bending the material.
  • A1/A2 Axes: Adjust for different plate thicknesses without changing gaps; also used for flip positioning.
  • B1/B2 Axes: Work with A axes to adjust gaps and height for precise positioning.
  • D1/D2 Axes (Optional): Die adjustment for reverse bending operations.
  • X1 Axis: Positioning axis for suction cups in material feeding.
  • X2 Axis: Back gauge stop finger positioning axis.
  • V Axis: Flip beam mechanical compensation axis.

Folding plate positioning method

sheet metal folding machine-Bending Beam Positioning
Suction Cup Positioning:
Back Gauge Positioning

Bending Beam Positioning:
The bending beam rotates to 90 degrees for positioning. The positioning size is determined by the stroke of the A-axis on the bending beam.

Suction Cup Positioning:
The bending beam rotates to 90 degrees for initial positioning. Subsequent bends are automatically positioned by the suction cups. Multiple processes in the same direction can be completed automatically.

Back Gauge Positioning:
Positioning is achieved by aligning the opposite side of the bending beam to ensure the internal void size of the product.

FOLDING TOOLING

The upper compression die for folded products, the angle and size of the upward bend depends on the avoidance position of the die.

folding tooling

The thicker the folded product is, the thicker the bending and turning mold will be, and the minimum thickness for forward and reverse folding depends on the thickness of the mold.
