MANDRELS

Inserted And Cable Mandrel Assemblies With Components For Rotary-Draw Tube Bending

Thirty years ago we introduced inserted mandrel and wiper tooling to the tube-bending industry. Our continuous improvement of inserted tooling design and manufacture (via Datafacturing®) has set the standard.

Our flex-link mandrel tooling line features the following:

  • Standard tooling available for round, square, and rectangular tubing with tube diameters from 1.000″ to 6.000″ (25mm to 152mm).
  • Plug mandrels available for smaller diameters; custom ball mandrels for larger diameters.
  • 1-“D” bending capacity.
  • Tough, long-life, single-piece, snap-together poppet-style links with heavy-duty detent systems for reliable “snap-back” upon the mandrel’s retraction from the tube bend.
  • Vented mandrel bodies for automated “through-the-mandrel” lubrication.
  • Standard with four wrench flats on mandrel bodies for easier installation to the machine.
  • Dozens of mandrel thread specifications (both inch and metric) are standard at no extra cost.
  • Long-life nickel-aluminum-bronze* nose inserts and mandrel balls for bending high-carbon steel, stainless steel, titanium, and nickel alloy tubing.
  • PVD coated steel nose inserts and mandrel balls for bending low-carbon steel, aluminum, copper, and aluminized stainless tubing.
  • Available as complete assemblies, sub-assemblies, and individual replacement components.

Our cable mandrel tooling line features the following:

  • Most durable multi-core wire rope for both greater flexibility and greater strength with tube diameters from 2.000″ to 4.000″ (51mm to 102mm).
  • Inserted or solid-body configurations available.
  • Tough alloy steel body (an aluminum-bronze body available at an additional cost).
  • Long-life nickel-aluminum-bronze nose inserts and mandrel balls for bending high-carbon steel, stainless steel, titanium, and nickel alloy tubing.
  • PVD coated steel nose inserts and mandrel balls for bending low-carbon steel, aluminum, copper, and aluminized stainless tubing.
  • Vented mandrel cables for automated “through-the-mandrel” lubrication.
  • Standard with four wrench flats on mandrel bodies for easier installation to the machine.
  • Available as complete assemblies, sub-assemblies, and individual replacement components.

* For mandrels smaller than 4″ (101.6mm) in diameter. For larger mandrels, non-nickel aluminum-bronze is available.

Instructional Video for Mandrel Assembly

Step-by-step video demonstrating the assembly and disassembly of Bend Tooling’s tough high-performance poppet-link mandrel assemblies. Includes information on how to do it and what tools you need to do it. For complete printed instructions, download our “Rotary Draw Tube Bending Guide”.

The Mandrel Nose Placement Calculator

This is a very helpful interactive utility that calculates the ideal placement of the mandrel nose. It also generates the ideal mandrel nose diameter for your specific application. This set-up tool should be used in conjunction with the “Forward Mandrel, Low Pressure” set-up technique outlined in our “Rotary Draw Tube Bending Guide”.
