Rectangular duct Y, asymmetrical: flat patterns
A rectangular trunk splits into two branches of different sizes, each leaning off the trunk's centre line at its own angle and running its own length, 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, each at its own angle, width and length, the outer corners rounded; five plates.
Sizes you enter
- Trunk width (W): Across the trunk, seen from above, on the surface chosen under Sheet.
- Trunk length (L): From the trunk's open end up its centre line to where the branches' centre lines leave it.
- Left branch angle (A1): Between the trunk's centre line and the left branch's.
- Left branch width (w1): Across the left branch, square to its centre line.
- Left branch reach (R1): Along the left branch's centre line, from where it leaves the trunk's to its end.
- Right branch angle (A2): Between the trunk's centre line and the right branch's.
- Right branch width (w2): Across the right branch, square to its centre line.
- Right branch reach (R2): Along the right branch's centre line, from where it leaves the trunk's to its end.
- 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).
