Bending tools from manufacturer - ALBROMET

SYSTEM-LINK MANDRELS

Our system link mandrels in best quality achieve high quality bending. They are exchangeable and can be used for a long time due to spare part sets.

Depending on the application and tube material ALBROMET offers tube bending tools made of different materials. In particular, bending mandrels and wiper dies are produced. We place value on highest material quality in order to minimize abrasion.

All tube bending tools are manufactured according customer drawings or designed by ALBROMET. As a manufacturer of tube bending tools, we place the highest value on function and design. The bending process is simulated by CAD, tested on function and collision. Most of the tools are made of hard aluminum bronze, therefore we achive a very good formability.

For other applications, for example non-ferrous metals, tube bending tools are produced from steel with coatings suitable for the application. The high-precision links between shaft and balls are made of tool steel in high-strength top quality.

Designs of system link mandrels

Standard System link mandrel - with NORMAL LUBRICATION

Advantage

  • fast delivery time
  • affordable price

Inquiry system link mandrel

Standard System link mandrel - with MINIMAL QUANTITY LUBRICATION

Advantage

  • low oil consumption
  • oil exit closer to bending area
  • better oil distribution due to compressed air feed of fluids
  • LBI lubrication system compatible 

Inquiry system link mandrel

sd-desing "small distance" (normal & minimal quantity lubrication)

Advantage

  • with 40% reduced ball distance
  • large contact area
  • wrinkle-free bending for thin-walled tubes

Inquiry system link mandrel

x-sd-design "extra small distance" (minimal quantity & normal lubrication)

Advantage

  • with 80% reduced ball spacing
  • reduced ball spacing due to smaller connecting links
  • for extremely thin-walled tubes
  • for difficult bending jobs
  • ​connecting links one size smaller

Inquiry system link mandrel

Plug mandrel

Advantage

  • for tubes with thick walls or
    diameter / wall thickness ratio >10%
  • available in different grades from ALBROMET

Inquiry plug mandrel

Formed mandrel

Advantage

  • for tubes with thick walls or
    diameter / wall thickness ratio >10%
  • 3D milled contour in the bending area
  • larger contact surface
  • for perfect bending result
  • available in different grades from ALBROMET

Inquiry formed mandrel

Spare parts system link mandrels

Bending segment (balls) different designs

Bending ball "standard design"

Bending ball "sd design"

Bending ball "x-sd design"

Attention! Variants can NOT be combined with each other.

 

 

Connecting links

Your Advantage

  • tensile strength > 1000 N/mm2
  • Elongation > 10%
  • Precise design
  • Metric system
  • Compatible with inch system
  • Accessories included
  • From stock, including standard part

 

The high-precision connecting links between the shaft and between the balls are manufactured from a heat-treated tool steel in high-strength top quality with extremely high strength and thus reduced operating costs. Due to in-house production, the investment costs stay affordable.

Spare part set

Your Advantage

  • Ready installed spare part
  • Replaceable with only one screw
  • Quick installation
  • Can be used again immediately
  • Short machine downtime
  • Available from ALBROMET in all variants
