Introduction

Bending a 10mm tube requires precision and the right approach to maintain integrity and achieve the desired shape. This article discusses methods and solutions for effectively bending a 10mm tube, with specific references to Hongli Pipe Machinery's solutions.

Preparation

Before bending a 10mm tube, you must consider the material composition, tube wall thickness, bending radius, and elongation capacity. Metal tubes like steel, aluminum, or copper each have unique properties affecting how they should be bent.

• Material Considerations: Understand the yield strength and ductility.
• Wall Thickness: Measure the tube's wall thickness, as thinner walls are more prone to buckling.
• Bending Radius: Use a suitable bending radius to avoid cracking.

Bending Methods

Mandrel Bending

Mandrel bending involves using a mandrel inserted into the tube to prevent collapse. Ideal for maintaining a precise radius and roundness in tubes.

Rotary Draw Bending

This method employs a rotating die and a pressure die to form precise bends, offering high accuracy for complex shapes.

Compression Bending

Involves pushing the tube against a stationary bend die. Suitable for larger radii but less precise than other methods.

Roll Bending

Uses a set of rollers to form large-radius bends. Not ideal for tight or complex bends but efficient for gradual curves.

Numerical Analysis

An understanding of stress distribution and deformation mechanics is essential for effective bending. Simulations show that:

• Yield Strength: A 10mm steel tube with yield strength of 250 MPa can be bent with a minimum radius of 40mm.
• Elongation At Break: Aluminum tubes with an elongation of >10% show minimal surface imperfections when bent.
• Springback: Account for springback, typically 2-3% of the bend angle for metals.
