Our chain link mandrels are designed with a bolt in shank link which is superior to a pinned link because this design allows the leverage strength of a shank link, and the pencil strength of a bolt over the sheer strength of a pin. For those who need a tighter bend radius we have designed the Useful-Tools hand operated mandrel tube bender. can make an integral link or a chain link mandrel to provide internal support. can supply a plug mandrel, a formed end MANDREL, or a ball mandrel, whichever would be most beneficial to your individual bend job.įor square or rectangle tubing T.B.C.

Plug Mandrels or Formed End Mandrelsĭepending on what the Tube Bending Concepts Tube Configurator suggests, T.B.C. Tube Bending Concepts has mandrels in standard sizes or can make custom sizes to fit any tube size. Mandrels can also be made with a durable plastic, eliminating the need for lube. Working with different tubing materials requires different mandrel materials. For example, stainless steel must be bent with an aluminum bronze mandrel. Aluminum Bronze or Tool Steel With Chrome Standby assemblies are a complete string of ball segments which make it faster to rebuild the high wear section of a mandrel. Replacement ball segments and standby assemblies can be ordered as well.

This improved mandrel design is available to fit tubing from Ø.625” to Ø 8.0”.

In 2000, Tube Bending Concets received a patent on Dura Link® linkage for ball mandrels.

I know full sized benders have a wiper to reduce the kinking here, but I doubt that's going to scale down very well.Dura Link® Universal Flex Mandrel Linkage If that doesn't kink then it's just a consequence of the stainless being much harder to pull round the former than the ally. I still need to see if there is any way of reducing this. Our team at Tube Bend understand the importance of this and do our very best to deliver all jobs on time with very competitive pricing. Builders and customers we work with need their jobs completed in a very timely manner. There is still a kink in the i/d at the start of the bend. Mandrel Pipe Bending, Metal Rolling & Handrails.

I was hoping for the best one to be a bit closer to 14mm, but it's not too bad. Check out our large inventory of hydraulic benders, mandrel tubing benders, and manual benders. The dimensions written on the tubes is the thickness after bending, from the i/d to the o/d. Pushing the mandrel in any further than the last photo resulted in a lock up of the mandrel in the bend, so that dictated the limit of its forward position.
#Mandrel tube bending trial#
I did 4 trial bends, the first without the mandrel inside the tube, and 3 more with the mandrel pushed a bit further past the tangent point of the bend each time. Mandrel bending can be a great solution for these devices, though it’s important to utilize experts in manufacturing as well as a powerful machine such as a CNC tube bender to avoid wrinkles or breaks in the tubing. The mandrel bit, which goes inside the tube, is just hardened silver steel, sized to be as close a fit to the bore as possible. Mandrel tube bends with tighter radii are requested from medical device and semiconductor manufacturers, as technology demands smaller components. I cut the half diameters with a 14mm ball nosed end mill, after hogging as much steel away with plain end mills.

Hopefully the principle is self explanitory from the pics. Remembering what a nightmare the V8 exhaust manifolds were to make, I decided to have a go making a mandrel bender for the V10 exhaust. Whilst on a slow period with my V8 I have been designing my next engine, which will be a 1/3 scale V10.
