Yes it is different from extrusion. Because in extrusion, a material is pushed through a die, but in this case, Drawing, the material is pulled. I mean in drawing process a material is stretched by applying tensile force...
Yes the mandrel has to be as long as (actually longer) than the tube itself. From what I have seen in CDS mills, the tubes are commony less than 20'. I'm sure in other mills, that length can increase.
What I don't understand is how far back the mandrel shaft can extend if the tube feed is continuous. For example, if the tube length is 50 feet, is the mandrel shaft 50 feet as well? For a tube that is made continuously, the mandrel shaft length would be continuous - a ridiculous construction. Would the tubing material - as in coiled copper tubing (500 foot rolls, let's say) formed around the mandrel shaft. Surely the shaft wouldn't be 500'!
Well for putting internal couplings on firehose there's a cone in the center of a bunch of shaped plates so when the cone retracts the plate expand. sort of like an umbrella. I doubt that makes sens but...

THIS IS ALUMINIUM DRAWING PROCESS IT IS DIFFRENT FROM MAIN STREAM DRAWING
So how was the initial tube made to be made into the smaller one?

夹头是怎么实现随着管材内径改变而缩小? 这样抽管之前就不用先缩管了

Should it be 50 feet long or simply move on a rail ?
normally a drawing process involved max 6 mt long bar. for continous tubing process is used something call floating drawer
Nice, keep up the awsome work
Nice video
how does the gripper diameter increase can somebody please explain?

Wow!
that is just perfec for my exposition thank you very much =D
thoda explain b krte..but good one
it just show general cold drawing theory principle，if you want grasp more detail information ,pls contract me
kudos for the upload !
Nice video! Why it has two mandrels?
one is gripper
how is the gripper supposed to increase its size then ??
some cam system. the video is stupid.

This is stupidity. Swag the one end for about 250 mm and insert this 250 mm end in die.now grip this with any two piece grip and now draw it
Its really weird, as the video shows us that...

hence we get infinite of material supply :D
thxz!
Certanly I m joining Mr Jeremy.Can anybody explain that?
How is the original tube made? Extruded?
A slab is thinned into a skelp which is then passed through rollers
It can be obtained either by extrusion( seamless tubes) or ERW method( welded).
This process and the call conform? someone can tell me
What software u use it?
Solid works I think
Who knows which software please
how is that different from Extrusion! Ugghh exams are tomorrow and I still dont get this
IB design is a pain ain't it
@@tonysen5583 yea ,, passed the exam tho
DO I need to tell you what the FUCK you can do with ALUMINUM TUBE? ALUMINUM!
