Hello, everyone. a question perhaps scema, with the common tools of bending there is possibility to make a ray fold like this? or if I ask something like that to a sheet metal supplier, does it make me pay a dedicated tool?

If there wasn't that funnel in the middle of the radius, maybe at fold strokes you can do (you might go under a press and with a punch you do it later).
But the one in the picture seems to be a piece made to be obtained with dedicated equipment.

difficult to do it well with bends
could be done with a first punching of the funnel on flat sheet and later central fold with punch with a cavity on which the protuberance falls.
looks like a commercial product then made in very large batches (google gives me as a result that it is a anti-rotation bracket of the cost of 0.60€) that could be obtained from press on mold or by casting with shelling machine

by fusion of what material? It seems to me that the thickness does not allow to be obtained by fusion, even if in shell.difficult to do it well with bends

You're right, I wrote a shit. No shelling.by fusion of what material? It seems to me that the thickness does not allow to be obtained by fusion, even if in shell.
the mold should be the best system in terms of production costs.
to obtain it by fold only if you make a few pieces and however between equipment, it needs a special central and one for the side folds, gear change and operator the costs are certainly not low.

Sorry I put an immagin I found online because I'm not in the office. was to give the idea, the request concerns only the ray fold, typical of these clamps

according to me of bending machine you can do; for the function that I imagine has that piece (type clamp for antenna poles), it could be fine even if it was made of only 4 folds to 45° (it would become a semi-octagon). then under a simple press (also a manual barbell), with a punch make the fun. the rest (the side wings) are normal administration for a bending machine. Of course, the holes must come out of the laser cut plate.You're right, I wrote a shit. No shelling.

Sure.according to me of bending machine you can do
perhaps what we see is only an example and the piece that must be done does not have the central funnel; Moreover to guess the reality of the demands is the standard.
Let's put it like this:
the piece quietly bends, however:
if you have the fun you need special equipment or some escamotage/compromise.
if it does not have the central embutitura and has a decent radius the sting makes it one tantum even with a trivial tube/tondino (thing from cellarers as someone would say, but optimizes the costs).
if it does not have the central embutitura and has strange radius the punch should be built specially
goes from if the price establishes the supplier according to how it works and the equipment it has in the house; the correct thing, as well as better, is to call it and compare it to be able to draw the detail making it as cheap as possible.

all these folds can be done with the normal bending tools, but also with the x axis back support, as long as the control is equipped with the lifting function (axis r) and automatic rear stop removal, as soon as the sheet is blocked by the punch.
it is necessary first to make the two extreme folds at 90° and the other two always at 90°.
the central curved part is done with twists, having the firmness to leave for the last 3 or 5 (if in odd number) or the 4 0 6 (if in even number) central folds, to avoid collision.
Last but not least, we make fun.
