Screw Type Sheet Bending Machine

About Screw Type Sheet Bending Machine

A screw type sheet bending machine uses a mechanical screw mechanism to apply pressure on a clamped sheet metal, forcing it to bend along a straight edge. It is ideal for making boxes, trays, panels, enclosures, and other fabricated sheet metal components.

Key Components:

1. Bending Beam (Bottom Tool): Holds the base where the metal is supported.

2. Clamping Beam (Top Tool): Applies pressure on the sheet using screws to fix it in position.

3. Screw Mechanism: Two mechanical screws (one on each side) move the clamping beam down to press the sheet.

4. Handle or Flywheel: Operates the screw mechanism (manually or motor-driven).

5. Angle Indicator (optional): Helps set the desired bending angle.

Working Principle:

1. The metal sheet is placed on the bending bed.

2. The clamping beam is brought down using the screws to hold the sheet tightly.

3. The bending beam is then lifted manually or with a lever to bend the sheet to the required angle.

Common Specifications:

Advantages:

• Low cost and easy to maintain

• Accurate and repeatable bends

• Suitable for custom or small-batch production

• No need for hydraulic or pneumatic systems

Limitations:

• Not ideal for thick or high-volume bending

• Manual effort is required

• Bending precision depends on operator skill
