Rectangular duct branch, 90°, rounded corners: flat patterns
A rectangular branch leaves a rectangular trunk square, the two corners where it leaves rounded for a smoother flow. The top and the bottom are cut to the plan with the rounds; the sides run from the trunk round each corner, pressed in facets, up the branch.
A rectangular branch square off a rectangular trunk, of one height, the corners where it leaves rounded; five plates.
Sizes you enter
- Trunk width (W): Across the trunk, seen from above, on the surface chosen under Sheet.
- Trunk, first end (A1): From the trunk's first end to where the branch's centre line crosses the trunk's.
- Trunk, second end (A2): From that crossing to the trunk's second end.
- Branch width (w): Across the branch, square to its centre line.
- Branch reach (R): Along the branch's centre line, from the trunk's centre line to the branch's end.
- Height (H): Across trunk and branch, seen from the front, the same all along.
- Corner radius (r): Of the two corners where the branch leaves the trunk, on the surface chosen under Sheet.
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).
