​Mandrel Bending Titanium Tubing

Mandrel Bending Titanium Tubing

Mandrel bending is a common method used to bend titanium tubing while maintaining its inside diameter and preventing distortion. When mandrel bending titanium tubing, proper techniques must be followed to ensure successful and accurate bending. The following are the general steps for mandrel bending titanium tubing:

Features and Functions

1. Select the proper mandrel: A mandrel is a solid rod or insert that is inserted into the tube during bending to maintain the inside diameter and prevent collapse. Select a mandrel with a diameter that matches the desired bend radius. 2.

2. Prepare the tube: Cut the titanium tube to the desired length, making sure there is enough extra length to accommodate the bend radius. Remove any burrs or sharp edges from the cut to prevent damage during the bending process.

3. Lubrication: Apply lubricant to the inside and outside of the tube. This helps reduce friction and prevents galling or scratching of the titanium surface during the bending process.

4. Set up the bending machine: Place the tube in the bending machine so that it is aligned with the bending die. Make sure the mandrel is properly inserted into the tube, extending along the desired bend line.

5. Bend the tube: Use the bender to slowly and smoothly bend the tube to the desired angle. Ensure that the tube is aligned with the bending die and that the mandrel is properly supported throughout the bending process. Take care to apply even pressure to avoid kinking or squashing of the tube.

6. Inspect the bend: After the bend is complete, carefully inspect the tubing for signs of distortion, cracking or defects. If any problems are found, the tubing may need to be cut and re-bent.

It is important to note that titanium is a strong and heat sensitive material. It is critical to use proper machinery and techniques when bending titanium tubing from the backshaft to prevent overheating or stress concentrations, which can lead to material failure. Maintain proper control of the bending process to ensure slow and controlled bending without excessive force.
