Tools for tubebending

Read more about the most important tools for our tubebending machines. All tools are manufactured in our own production in Värnamo.

Bend die

Made of hardened steel and with the fixed jaw screwed or welded for optimal transition between straight part and radius. For increased quality, the profile can be deepened or made elliptical

Clamp die

Made of hardened steel. Recommended lock length 3 x pipe diameter. For shorter lock lengths, the profile can be grooved for a better grip. In other cases, recesses are milled for bracket in bracket. In some cases without a straight span.

Pressure die

Made of hardened steel. If a fixed (stationary) support rail is used, the support rail length is recommended to be 4 x the diameter of the pipe. In case of running support rail or support rail push-on, the length is recommended to be 2 x the pipe diameter plus half the circumference of the profile board (bending to 180 degrees).

Mandrel

For tight radius and thin wall thicknesses. Manufactured from steel or Ampco.

Wiper die

For tighter radius and thinner wall thicknesses. Made in steel or Ampco.

Bend die

The bending die is mounted so that the fixed jaw is parallel to the bending direction.

Clamp die

Check that the height matches the bending die and that the jaw is parallel to the bend die’s jaw. Adjust the locking pressure so that the pipe does not slip in the jaws during bending.

Pressure die

Insert a pipe into the clamp die and lock it in place. Slide the pressure die against the pipe and lock it in place. In principle, the pressure die should lie against the pipe without pressure. If necessary, re-adjust in small steps.

Mandrel

Select the type of mandrel according to the table. Set the mandrel so that a part of the mandrel body, max. approx. 0.5 x the inner diameter of the pipe, is in front of the center of the tool. Try different positions for best results.

Wiper die

Lock a tube between the clamp die and place it next to the pressure die. Then push the wiper die forward as far as possible, the tip should then be almost in front of the center of the bend die, and lock it in place. The wiper die should be parallel to the bend die or with the rear part slightly further away from the pressure die.
