2. Safety Instructions

To prevent injury and ensure proper operation, observe the following safety guidelines:

• Always wear appropriate personal protective equipment (PPE), including safety glasses and gloves, during operation.
• Ensure the bending machine is securely mounted to a stable workbench or floor before operation. Instability can lead to accidents.
• Keep hands and fingers clear of moving parts and the bending area during operation.
• Do not attempt to bend materials that exceed the machine's specified capacity. Refer to the specifications section for limits.
• Inspect dies and machine components for damage or wear before each use. Replace worn or damaged parts immediately.
• Maintain a clear, well-lit, and organized work area to prevent tripping hazards and ensure visibility.
• Do not operate the machine under the influence of drugs, alcohol, or medication that may impair judgment or coordination.
• Children and unauthorized personnel must be kept away from the operating area.

3. Product Overview

The VEVOR Manual Bending Machine UM30 is engineered for precision and durability. Key features include:

• Exceptional Bending Capability: Supports up to 2-inch wide flat steel or steel plates, 0.65-inch O.D. hollow round pipes, and 1-inch O.D. round steel tubes. Capable of bending low-carbon steel under 0.2'' thick and aluminum under 0.4'' thick, with a maximum bending angle of 200 degrees.
• 14 High-Quality Dies: Includes 7 bending dies (1", 1-1/4", 1-1/2", 1-3/4", 2", 2-1/2", and 3") and 7 round pipe dies (1", 1-1/4", 1-1/2", 1-3/4", 2", 2-1/2", and 3"), suitable for various material shapes and sizes.
• Durable Carbon Steel Construction: Made from high-strength carbon steel for long service life and reliable performance.
• Ergonomic Design: Features a long handle with a non-slip rubber grip for secure handling and reduced effort during bending operations.

4. Setup

Follow these steps to set up your VEVOR Manual Bending Machine:

1. Unpacking: Carefully remove all components from the packaging. Verify that all parts listed in the packing list are present and undamaged.
2. Base Mounting: Secure the machine's base to a sturdy workbench or concrete floor using appropriate bolts and anchors (not included). Ensure the machine is stable and does not wobble during operation.
3. Handle Assembly: Attach the long operating handle to the main bending arm. Ensure it is securely fastened with the provided hardware.
4. Die Installation: Select the appropriate bending die and round pipe die for your material. Insert them into their respective positions on the bending arm and secure them with the provided pins. Ensure they are correctly aligned and seated.

5. Operation

Operating the bending machine requires careful attention to detail:

1. Material Preparation: Measure and mark the precise bending point on your pipe or tube. Ensure the material is clean and free of obstructions.
2. Die Selection: Choose the correct bending die and counter die (round pipe die) that precisely matches the outer diameter of your material. Incorrect die selection can lead to material damage or improper bends.
3. Material Insertion: Place the pipe or tube between the selected dies. Ensure the marked bending point aligns with the center of the bending die.
4. Bending: Slowly apply steady, continuous force to the long operating handle. Observe the material as it bends. The machine allows for a maximum bending angle of 200 degrees. Avoid sudden jerks to ensure a smooth bend.
5. Inspection: After bending, release the pressure and carefully remove the bent material. Inspect the bend for accuracy and any signs of material stress or damage.
6. Repeat: For multiple bends, reposition the material and repeat the process as needed.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your bending machine:

• Cleaning: After each use, clean the machine and dies to remove metal shavings, dust, and debris. Use a dry cloth or brush.
• Lubrication: Periodically apply a light machine oil to all pivot points, pins, and the surfaces of the dies to ensure smooth operation and prevent rust.
• Inspection: Regularly inspect all components, especially the dies, pins, and handle, for signs of wear, cracks, or damage. Replace any worn or damaged parts immediately to maintain safety and performance.
• Storage: Store the bending machine and its dies in a dry, clean environment to prevent corrosion. Keep dies organized to facilitate quick selection.

7. Troubleshooting

Address common issues with the following troubleshooting steps:

• Pipe Crushing/Deformation:
  • Cause: Incorrect die size, material too thin for the die, or excessive force applied too quickly.
  • Solution: Ensure the selected dies precisely match the outer diameter of the pipe. For thinner materials, consider using a filler or a different bending method if the issue persists. Apply force gradually.
• Inconsistent Bends/Spring-back:
  • Cause: Material properties (e.g., spring-back in harder metals), inconsistent force, or improper die alignment.
  • Solution: Over-bend slightly to compensate for spring-back. Ensure dies are securely installed and aligned. Apply consistent pressure throughout the bend.
• Difficulty Bending:
  • Cause: Material exceeds machine capacity, insufficient leverage, or lack of lubrication.
  • Solution: Verify the material's dimensions and type are within the machine's specifications. Ensure the handle is fully extended for maximum leverage. Lubricate moving parts and dies if resistance is high.
• Machine Instability:
  • Cause: Improper mounting of the base.
  • Solution: Re-secure the machine's base to a stable surface. Check all mounting bolts for tightness.
