Introduction to Small Radius Tube Benders

Small radius tube benders are specialized machinery designed for precise bending of tubes and pipes with relatively tight radii. They are frequently utilized in industries where space constraints and intricate designs require compact bends.

Mechanical Principles of Tube Bending

Tube bending involves transforming the straight and often rigid tubes into a desired angle or shape without compromising their structural integrity. This is typically achieved through mechanical force in a controlled manner, ensuring the tube's wall thickness remains consistent.

Key Components of Small Radius Tube Benders

Small radius tube benders comprise several essential components:

• Die: Shapes the tube as it is bent, ensuring the desired radius is achieved.
• Clamp: Holds the tube in place during bending to maintain precision and accuracy.
• Pressure Dies: Apply force evenly on the tube to prevent deformities.

Process Description and Parameters

The tube bending process involves several key steps and parameters that influence the outcome:

• Tube Diameter: A crucial factor in determining the bending force required.
• Bending Radius: Small radius bends typically range between 1 to 5 times the tube diameter.
• Material Properties: Different materials, such as steel, copper, and aluminum, have unique stress-strain characteristics.

During bending, the tube is positioned in the bender using the clamp. The die, coupled with hydraulic or electric force, then bends the tube around a predetermined radius while the pressure dies provide necessary support to counteract the forces that might cause kinks or flattening.
