Rectangular duct Y, symmetrical: flat patterns
A rectangular trunk splits into two equal branches either side of its centre line, at whatever angle the run needs, the outer corners rounded and the crotch sharp. Five plates: the top and the bottom cut to the Y, the crotch bent once, and two sides pressed round their corners.
A rectangular trunk splitting into two branches either side of its centre line, the outer corners rounded; five plates.
Sizes you enter
- Trunk width (W): Across the trunk, seen from above, on the surface chosen under Sheet.
- Branch width (w): Across each branch, square to its centre line.
- Angle between the branches (A): Between the two branches' centre lines, half of it either side of the trunk's; more than 0°, up to 180°.
- Branch reach (R): Along a branch's centre line, from where it leaves the trunk's to its end.
- Trunk length (L): From the trunk's open end up its centre line to where the branches' centre lines leave it.
- Height (H): Across trunk and branches, seen from the front, the same all along.
- Corner radius (r): Of the outer corners where the branches leave the trunk, on the surface chosen under Sheet. 0 for sharp.
What you get
The exact flat pattern of the part, worked out for the sheet thickness measured on the inside, the mean or the outside, with numbered press lines, the part in 3D, its weight and cutting length, and a DXF for laser, plasma or waterjet cutting (STEP as well).
